+# AI Disclosure
+
+This is a disclosure of the use of AI in this project.
+
+## AI Use
+
+Anyone who demands the dislosure of how AI was used in an engineering project,
+has no idea what AI is, or how it works. 
+
+AI was used in this project as a tool. Several contributors used AI in their
+commits, and so you will see like 7 commits by Claude or Codex or Cursor.
+
+However those commits were reviewed by human beings, and it was declared that
+the exact same fix would have been done by a human, so they were accepted.
+
+AI was not used to make decisions, or to create the project.
+
+If you would like to read more, well then continue reading:

-### 5. `mod.card`
+### 5. What a mod's code can reach
+
+Your code runs in a sandbox (`src/mods/Sandbox.lua`), not against the
+engine's globals. Every chunk you author gets it: `main.lua`, your
+`options_schema`, and anything you `load()` yourself.
+
+The globals the sandbox took away are still *reachable*, as compat
+stand-ins (`src/mods/LegacyCompat.lua`) that answer with the new API
+underneath. A mod written before the sandbox keeps working; it logs one
+warning per call it should migrate, and the mod manager lists them. What
+each stand-in actually does:
+
+| Pre-sandbox call | What it does now | Migrate to |
+| --- | --- | --- |
+| `io.open`, `io.lines`, `love.filesystem.read`/`lines`/`newFile` | reads your own shipped files, then your overlay, then `mod.storage` | `mod:read`, `mod.storage` |
+| `love.filesystem.write`/`append`, `io.open(…, "w")`, `os.remove`, `os.rename` | writes to a private per-mod overlay under `mod_compat/<your id>/` | `mod.storage` |
+| `love.filesystem.getDirectoryItems`/`getInfo` | your own directory plus your overlay | `mod:list`, `mod:info` |
+| `love.filesystem.getSaveDirectory` and friends | a virtual root; anything joined to it lands in your overlay | `mod.storage` |
+| `os.getenv` | `nil`, except home-like names, which answer with that same virtual root | nothing |
+| `love.filesystem.load`, `dofile`, `loadfile` | compiles the chunk into your sandbox | `require`, `mod:read` plus `load` |
+| `love.system` | `getOS`/`getPowerInfo`/`getProcessorCount` read through; clipboard and `openURL` do nothing | `mod.device:powerInfo()`, `mod.steps` |
+| `love.event` | passes through, except `quit`, which does nothing | `mod.events`, `mod.hooks` |
+| `love.mousemoved = fn` and the other callbacks | installs on the real `love` table, the way it always did | `mod.hooks`, `mod.events` |
+| `package` | an inert stub, so `package.path = …` does not crash | `require` |
+
+What has no stand-in, because there is nothing honest to reroute it to:
+
+| Still refused | Why |
+| --- | --- |
+| `love.thread` | a LÖVE thread is a fresh Lua state with the full standard library, which no environment-based sandbox in this state can reach. Use `mod.fetch` for background HTTP (`network`) or `mod.job` for background compute (`background`) — both run your code inside the sandbox instead of outside it |
+| `require("ffi")` | arbitrary C |
+| `debug`, `getfenv`, `setfenv` | each one undoes the sandbox from inside |
+| `io.popen`, `os.execute` | spawning a process |
+| `love.run`, `love.errorhandler` | the engine's own loop and its crash path |
+| replacing a `love` module table (`love.filesystem = {}`) | the engine reads those tables too |
+
+The rest of `love` passes through unchanged, so graphics, audio, timers and
+input work as they always have.
+
+Three consequences worth knowing before you write against it:
+
+- **Your globals are yours.** `_G` inside a mod is that mod's own table. Two
+  mods no longer share a namespace, and neither can reach the engine's. To
+  publish something to another mod, put it on `mod.exports` and let them
+  `mod.find("your_id").exports` — the channel that was always the intended
+  one. The same goes for the standard library: `string`, `table` and `math`
+  are per-mod copies, so patching one is a local decision.
+- **Paths cannot climb.** `mod:read`, `mod:list`, `mod:info`, `mod.assets:path`
+  and `mod.assets:image` join to your own directory, and `..`, absolute paths
+  and drive letters are refused. So are `entry` and `options_schema` in your
+  manifest. `mod:list("assets")` is the sandboxed `getDirectoryItems` for a
+  folder you shipped; `mod:info` tells file from directory so a walk can
+  recurse.
+- **Ship source, not bytecode.** A precompiled entry file is refused.
+
+`permissions` in the manifest is still a disclosure the manager shows the
+player. `network` gates `require("socket")` and friends plus `mod.fetch`
+(non-blocking HTTP), and `background` gates `mod.job` (compute on a worker
+thread). Those two are the sanctioned ways to work off the main thread now
+that `love.thread` is refused. There is no
+permission that grants raw filesystem access, because no mod needs one:
+everything a mod legitimately writes is already scoped by
+`mod.storage` or the asset-transform derived root.
+
+If your mod used one of the rerouted globals, the fix is almost always
+`mod.storage`. The overlay is a compatibility floor, not a second storage
+system: it is not scoped per playthrough, it does not migrate, and it is
+the first thing that will be dropped once the mods on the index have
+moved off it. Open an issue if you have a case `mod.storage` does not
+cover.
+
+### 6. `mod.card`

 The manifest is the *engine's* contract: identity, load order, dependencies,
-permissions, profile. The card is the *human-facing* one: who made this,
+permissions, profile (see [Manifest specification](docs/modding.md#manifest-specification-manifestjson)).
+The card is the *human-facing* one: who made this,
 what it changes, what it does not do yet. It is never read by the loader's
 merge — only by tooling and the manager's detail pane — so an absent or
 malformed card can never break a load.

-
-**Re-import the Gold cache.** Seven fixes live in the extractor and the manifest
-tool, so they do nothing until the ROM is re-imported. This was verified still
-outstanding on 2026-08-10: the default identity's
-`gold/data/generated/menu_gfx.lua` has no `trainerPics` key at all, so a trainer
-battle still opens on the mon rather than the trainer even though the Lua half
-is fixed and correct.
-
- trainer frontpics (`TrainerPicPointers` walk in `extractMenuGfx`), which is
-  the missing trainer intro image at the start of a trainer battle. The Lua
-  side is now right and re-import is the ONLY thing left: `Trainers.lookup`
-  returns a numeric `class` (36) beside a `classId` (`BUG_CATCHER`), and both
-  `menu_gfx.trainerPics` and `palettes.trainers` are keyed by the constant, so
-  the lookup had to move to `classId`. On a cache that carries the pics the
-  frontpic renders in the class's own palette.
- egg assets: `battle/front/egg.png` and `menu/egg_hatch.png`, feeding the
-  hatch cutscene and the summary screen's egg page. A fallback landed in the
-  meantime (`ICON_EGG` frame 0, which resolves to a real 16x16 frame), so the
-  egg page draws SOMETHING on a stale cache; `tools/rom_manifest_gold.json`
-  carries `EggPic` at `[20, 31363]` and that stream decompresses to exactly 400
-  bytes (a 5x5-tile pic), so a fresh import takes the real path.
- the Pokegear phone icon. `_LoadFontsExtra` (`engine/gfx/load_font.asm:8-15`)
-  puts `FontsExtra_SolidBlackAndUpArrowGFX` at `$60`/`$61` and
-  `PokegearPhoneIconGFX` at `$62`, ON TOP of `FontExtra`'s BOLD_A/B/C.
-  `src/import/RomExtractorGen2.lua:342-356` reads `FontExtra` straight in and
-  then blits only `Frames` over `$79-$7E`, so `$62` is still a bold "C" -- which
-  is what the new caller box draws where the telephone glyph belongs. Fix is two
-  files: add the two GFX symbols to `tools/rom_manifest_gold.json`, then blit
-  them at `$60`/`$61`/`$62` in the loop that already handles `Frames`.
- `PREDEFPAL_UNOWN_PUZZLE = 76`, which is why the Ruins of Alph puzzle rendered
-  grayscale instead of brown
- the tilemap pad `0x7f -> 0x4f` in `readTilemapRLE` / `readFlatTilemap`
- held-item icons (`HeldItemIcons` in the manifest, `out.heldItem` in
-  `extractIcons`), which is the held-item marker in the party menu
- the NPC-trade rows' `item` field, which is what made the Violet City Onix's
-  Bitter Berry print as "83"
-
-## Open: real unknowns, each needs a cache and a driver run
-
-1. **Magnet train renders a blank field.** Pushing `World:magnetTrain` directly
-   shows nothing for 90+ frames (see shot `03-magnet-train.png`). The screen's
-   surround is correct now; what was never investigated is whether
-   `drawBackground` needs setup that the direct push skips. This cannot be
-   settled by reading source.
-
-2. **The NPC that introduces Unown never appears.** Round 1 could not produce a
-   port ref that diverges from the asm, so it is filed `cannot_locate`, not
-   fixed. The cart chain is: solve a chamber puzzle, then
-   `setmapscene RUINS_OF_ALPH_INNER_CHAMBER, SCENE_RUINSOFALPHINNERCHAMBER_STRANGE_PRESENCE`
-   from `maps/RuinsOfAlphKabutoChamber.asm`. Walk that chain live rather than
-   statically: the static read came back clean twice.
-
-3. **Two pic sites still resolve an Unown off the species.**
-   `src/ui/gen2/PhotoStudio.lua:102` and `src/ui/gen2/EvolutionAnim.lua:460` use
-   `def.spriteFront` without going through `Unown.formSprite`. For EvolutionAnim
-   this is almost certainly dead (Unown does not evolve). For PhotoStudio it is
-   genuinely unclear: the cart's `engine/events/print_photo.asm` does not call
-   `GetUnownLetter` at all, so the port may already match. Check before changing.
-
-4. **Unown dex registration on obtain paths.** `engine/pokemon/evolve.asm:310`
-   runs `GetUnownLetter` then `callfar UpdateUnownDex` after
-   `SetSeenAndCaughtMon`, guarded by `cp UNOWN`. That is dex bookkeeping, not
-   rendering, and it was never audited across every path that gives the player a
-   mon. `GetUnownLetter` has 20 call sites on the cart; the port covers the pic
-   ones.
-
-## The 2026-08-10 mod-API round
-
-Six lanes closed the Gen 1 / Gen 2 mod-API boundary and a batch of reported
-gameplay bugs. What that round **closed**, so nobody re-opens it:
-
- Fifteen seams that had a Gen 2 site but no entry in the parity gate are now
-  listed and asserted: the four `intro.oak_speech.*` events plus the
-  `intro.oak_speech.build` hook, `battle.overlay`,
-  `battle.low_health_alarm`, `battle.catch_exp`, `pokemon.sprite`,
-  `input.step`, `input.pointer`, `render.zones`, `render.compose`,
-  `render.letterbox`, `render.hud`. Five more (`intro.boot.*`) are listed as
-  Gen 2-only. `tests/engine/gate_gen2_mod_api.lua` is 893/893.
- Two registries un-gated on Gold after their consumer landed:
-  `battle_sprite_scales` (`src/ui/gen2/BattleState.lua:imageScale`) and
-  `render_pipelines` (`src/core/Game2.lua:load` installs
-  `src/render/Pipelines.lua` on the merged dataset after `mods:load`). Both
-  keep the SHARED Gen 1 target, so one mod record serves both games. 40 of the
-  46 registries are now available on Gold.
- `hook:render.zones` came off the `gate_meta_coverage.lua` DEBT ledger, which
-  is now four entries, all M7/M12 link and give-mon seams.
-
-What that round **left open**, each verified on 2026-08-10:
-
-1. **`render_pipelines`' `drawWorld` half is inert on Gold.** Gold's overworld
-   draws straight to the window rather than into a canvas the way
-   `src/world/OverworldController.lua` hands one to `Pipelines.drawWorld`, so a
-   drawWorld-only pipeline renders nothing. It is not left switched on
-   pretending: `Game2:load` retires a restored level for one and re-applies
-   Tilt from the option the exclusion just cleared, leaving
-   `options.pipelines` untouched so the mode returns the day Gold grows a world
-   canvas. Related: `Pipelines.rows` is read only from
-   `src/ui/OptionsMenu.lua`, so a pipeline on Gold has a hotkey and no OPTION
-   row.
-
-2. **`transitions` stays gated and should.** `src/ui/gen2/BattleTransition.lua`
-   keys `STYLES` as a boolean SET of the four cart wipes (`spin`, `speckle`,
-   `zoom`, `sine`), not the `{ frames, draw, sound, flash }` record the
-   registry carries, and there is no styleDef lookup a mod id could reach --
-   a registered style would fail the membership test and fall back to vanilla.
-   Un-gating it before that changes would be the silent no-op the routing table
-   exists to prevent. Same for `rulesets`, `field`, `text_pointers`,
-   `link_fields` and `map_scripts`; `docs/mod-api-gen2-compat.md` carries the
-   per-registry reason.
-
-3. **`src/core/Game2.lua:joystickremoved` is half of Gen 1's.**
-   `src/core/Game.lua:867` does `self:recoverInput("joystickremoved", joystick)`
-   AND `TouchControls:joystickremoved()`; Game2 does only the pad half, so a
-   controller unplugged mid-hold leaves Gold's Input state stranded and a held
-   direction walks forever. It was a total noop before, so this is not a
-   regression -- it is a seam finished halfway. One line.
-
-4. **`Game2` noops five joystick callbacks.** `joystickpressed`,
-   `joystickreleased`, `joystickaxis`, `joystickhat` and `joystickadded` are
-   assigned `noop`, so a stick with no SDL game-controller-database entry
-   reaches neither Input nor `GamepadMap.RAW_BUTTON_BINDINGS` on Gold. Gen 1
-   handles all four (`src/core/Game.lua:764-797`). A DualSense is
-   SDL-recognized and takes the gamepad path, so this is not the reported
-   SELECT bug -- it is the raw-stick fallback.
-
-5. **`Game2:gamepadpressed` has no SELECT-held guard.** Gen 1
-   (`src/core/Game.lua:686-694`) suppresses the shoulder GAME SPEED cycle while
-   SELECT is held, because Select+L is a display chord on NX. Harmless today
-   (Gold has no display chord) but the two paths have diverged.
-
-6. **`hideCallerBox`'s fallback path skips the screen seams.**
-   `src/script/gen2/CallAsm.lua:217-231` pops through `stack:pop` when the
-   caller box is top (which it always is on a normal call, since `PhoneRing`
-   runs `closetext` before `InitCallReceiveDelay`) but falls back to a bare
-   `table.remove(states, index)` otherwise, which raises neither `exit` nor
-   `screen.popped`. Only a mod screen pushed over the box can reach it, and
-   then a listener that saw `screen.pushed` never sees the pop.
-
-7. **`src/core/gen2/Roamers.lua:338` says the wrong thing.** Its comment says
-   "the shared `encounter.species` hook still runs downstream and is where a
-   mod changes what appears". It does not: `World:tryWildEncounter` calls
-   `startBattle` on a roamer hit and RETURNS before it reaches
-   `World:rollEncounter`. The doc's partial-coverage list is right and the
-   comment is wrong; correct the comment, not the doc.
-
-8. **`src/world/gen2/World.lua:4318` still calls the pack's SEL row something
-   "this port has not built".** The pack submenu now offers SEL. Stale comment.
-
-Three partial coverages that are documented and still true, repeated here
-because "the hook exists" is not "the hook sees everything":
-`encounter.roll` / `encounter.species` are not wired into `World:tryHeadbutt`,
-`World:rockMonEncounter` or the roamer path; `src/ui/gen2/BattleState.lua`
-builds a flat `opts` for `Catching.attempt` with no `data` in it, so a
-mod-registered ball is readable through `Catching.recordFor` but is not
-resolved at the real throw site; and no Gen 2 UI file reads
-`Battle.statusRecordFor(data, status).hudLabel`, so a mod status shows no label
-in the battle HUD, the party menu or the summary page.
-
-## Open: cleanups declined on purpose
-
-These were skipped with reasons during the wiring pass. They are listed so the
-reasons survive, not because they are pending work.
-
-1. **`Vm:showRaw(body, stay)`** was proposed and declined. `showRawHeld` in
-   `Specials.lua` already answers the text lookahead correctly, so this trades
-   one working shape for another.
-
-2. **`tests/drivers/gold_egg_hatch.lua` summary push** was declined as
-   redundant: `gold_egg_hatch_shots.lua` already photographs both the cutscene
-   and the summary page.
-
-3. **Two `Battle.lua` divergences** were filed as notes by the file's own owner
-   rather than fixed, because no reported symptom drives either: text printed
-   for an already-statused target, and Future Sight taking STAB, type
-   effectiveness and weather. Both are real divergences from the cart. Fix them
-   when something actually depends on them.
-
-## Reported, investigated, and NOT defects: do not re-chase these
-
-Each of these came in as a bug report and came back disproved against the asm.
-Re-opening one costs another full investigation, so the reasoning is kept here.
-
- **SFX pointer table misalignment.** The table is aligned end to end. 188 `dba`
-  rows with no skips or padding, 188 constants, verified through the manifest
-  scraper, the extractor's `*3` stride, and 8 ids spot-checked against the live
-  cache. Two things that look like misalignment are how the cart is built:
-  `SFX_GET_EGG_UNUSED` and `SFX_GET_EGG` both point at `Sfx_GetEgg`, and
-  `Sfx_ReadText` / `Sfx_ReadText2` share one header address. **Do not repoint,
-  re-stride, or add an offset to the SFX, music, or cry tables.**
-
- **Bind letting you pick other moves.** This is Gen 1 behavior and does not
-  hold for Gen 2. `BattleCommand_TrapTarget` (`effect_commands.asm:5568-5605`)
-  writes only the TARGET's wrap count and trapping move. It touches nothing on
-  the user, so the user is free to switch moves. The port is correct. The real
-  Gen 2 move locks (Rollout, Thrash, Petal Dance) were genuinely missing and
-  have been added.
-
- **The Slowpoke Tail salesman not blocking progression.** He is Route 32's
-  `FISHER4` at (7,70), not an Azalea Town object, and the cart's refusal arm
-  only prints. `_OfferToSellSlowpokeTail` runs `setscene SCENE_ROUTE32_NOOP`
-  first, so the coord event never fires again. There is no pushback to port.
-
- **The rival being named BLUE.** Not reproducible. The whole chain is intact:
-  special 36 resolves to `H.NameRival`, `NamingScreen:accept` hands the typed
-  string through, and BLUE is the Gen 1 default that Gold never reaches. A
-  separate real defect on this seam (the rival being pre-named SILVER before the
-  officer asks, and the blank-entry fallback) was found and fixed.
-
- **Not Very Effective dealing 0 damage**, **status not shown in the battle
-  UI**, and **the Pokedex missing from the Start Menu** all came back
-  `already_fixed`: the damage floor is `MIN_DAMAGE` added after the cap and
-  before the type multiply, the HUD prints the status tag where the level goes,
-  and the menu row is gated on `save.engineFlags[11]` correctly.
-
-## Standing risks, not breakage
-
- **Four Gold test files are wired into no runner**, so a regression in them
-  will not turn `run_tests.lua` red: `gold_flag_names_test`,
-  `gold_route_validate_test`, `gen2_pokegear_unlock_test`,
-  `gen2_save_export_test`. All four pass standalone. The first two are the
-  pre-run route validators documented in `KANTO-CONTINUE.md`; the last two need
-  a `GOLD_CACHE` and are excluded by an in-file comment. This is deliberate, but
-  it is a coverage hole and worth knowing.
-
- **`mods/` must stay clean.** The 2026-08-10 round left temporary probe mods
-  behind mid-run (`mods/tmp_menus`, `mods/zz_verify_seams`); both are gone now
-  and `mods/` holds only `example_mew_starter`, `example_silly_oak`, `examples`
-  and `nuzlocke`. A stray `mods/tmp_*` loads on every Gold boot and changes what
-  a driver measures. `mods/example_silly_oak` carries only a `.modkitignore` and
-  warns "manifest.json does not exist" on every boot; that is pre-existing
-  (27 Jul) and unrelated.
-
- **`tests/drivers/gold_opaque_surround.lua` is stale.** It reads
-  `game.stack._items`; `src/core/StateStack.lua` has only `.states`. That branch
-  is covered instead by `gold_center_pc` and the letterbox-per-frame count in
-  `gold_frame_seams`.
-
- **`luac` on this machine is Lua 5.5**, so `luac -p` is a weak proxy for the
-  LuaJIT/5.1 semantics this engine targets. Use `luajit -b <file> /dev/null` for
-  a real syntax gate.
-
- **`docs/rfcs/0001-surfing-pikachu-sprite.md` and `0002-screen-render-visible.md`
-  are deleted** in the working tree, and both are still referenced by name from
-  live modkit case files that pass. Those deletions predate both parity runs.
-  Worth resolving before a commit.
-
-## The failure mode that actually bit, worth remembering
-
-Round 1 reported the Yes/No dialogue fix as landed. It was not. Two of its three
-lanes wrote their half, and the third left the hook closure at
-`World.lua:828` declared as `function(body, onDone)`, so the third argument
-`Vm:resume` passes was silently discarded and the entire `stay` implementation
-in `World:showText` and `World:askYesNo` was dead code. Lua drops extra
-arguments without complaint, so nothing failed and every suite stayed green.
-
-Round 2 caught it only because an investigator probed the boundary empirically
-instead of reading both sides and assuming they met. When work is split across
-agents by file, **the seams between the files are where the bugs live**, and a
-green suite does not prove a seam is connected.

-# KANTO-CONTINUE: executing the never-run half of Gold (sections 19-32)
-
-Deferred from the 2026-08-09 fix campaign by request. This doc is self-contained: the
-audit documents it was distilled from are being retired, so everything a future session
-needs is here.
-
-## What this is
-
-The Johto main line (walkthrough sections 00-18) is proven: the route bot beats Champion
-Lance with every row passing. Kanto (sections 19-32) is extracted and wired but has
-NEVER been executed by any bot row, driver, or human. Every entry below reads clean in
-static review (cache + code + cart source were cross-checked adversarially); the risk is
-purely runtime. The job: make each beat actually run, fix what breaks, and leave
-executable evidence (bot rows or assertion drivers) behind.
-
-## State after the 2026-08-09 campaign (what changed under you)
-
- ~80 defects fixed across the port; 91/91 gen2 suites, engine 128/128, T3 all green.
- The post-game handoff WORKS now: post-E4 credits end at the title screen, and
-  CONTINUE consumes the post-game spawn (HallOfFame.consumePostGameSpawn): after Lance
-  you continue in NEW_BARK_TOWN, after Red at SILVER_CAVE_OUTSIDE (23,20). Section 19
-  is reachable by normal play for the first time.
- The Snorlax wake chain is fully functional (engine-flag bridge unlocks the Pokegear
-  and EXPN card; the tuned radio song persists after closing the gear; SnorlaxAwake
-  fires; proven live by tests/drivers/gold_radio_persist.lua).
- Landed systems Kanto beats depend on: phone random/outgoing calls, field item use
-  (Escape Rope/Dig via save.backupWarp), Repel, swarms, Rock Smash encounters,
-  waterfall current tiles, roamer scatter on CONTINUE, trap volatiles + FORCESHINY
-  battle types (beast catching in section 32 is now mechanically possible), badge
-  boosts, held items, specialty balls (Lure Ball needs battleType 'fish', already
-  stamped by updateFishing).
- NPC HOUR WINDOWS are now enforced (they were not when the Johto route was authored).
-  Any Kanto row that talks to a time-gated NPC must pin the clock (POKEPORT_GOLD_HOUR /
-  POKEPORT_GOLD_DAY) or handle absence. Only 11 hour-gated objects exist on the whole
-  cart: CELADON_GAME_CORNER 6/7, GOLDENROD_GAME_CORNER 4/5, MOUNT_MOON_GIFT_SHOP 1-4,
-  and the three Moms in PLAYERS_HOUSE_1F; Celadon and Mt Moon are the Kanto exposures.
- The game clock now anchors on every new game (cart InitClock semantics), so time of
-  day no longer follows the host wall clock in driver runs; POKEPORT_GOLD_HOUR pins
-  the anchored base too. Runs are reproducible across day/night; a pre-existing flake
-  class (night runs catching HOOTHOOT where day runs catch PIDGEY, shifting grind
-  levels) died with it.
- Battles hit harder both ways since the cart MIN_DAMAGE floor landed; grind budgets
-  tuned for the old numbers may need a nudge.
-
-## Known bot weaknesses to expect (verified pre-existing, not campaign regressions)
-
- Pathfinding pocket: travel into ILEX_FOREST / SLOWPOKE_WELL bounces (probe
-  CHERRYGROVE_CITY>ILEX_FOREST reports no route), and route row 16.54 gives up the
-  walk to VICTORY_ROAD_GATE with the identical TELEPORT signature in every logged run.
-  Kanto routing should waypoint doors explicitly per the ops recipes above.
- Optional buy rows 04.5d and 18.g4/18.g5 fail whenever the wallet is empty at that
-  point in the run; they are budgeting gaps in the route, not engine bugs.
- Grind row 08.g (Route 41 water) has almost no margin; with the clock now anchored
-  its inputs are stable, but a low-level POLIWAG catch can still stretch it.
-
-## How to run things
-
-Identity/cache: gold-dev (~/Library/Application Support/LOVE/gold-dev/gold), rebuilt
-2026-08-09 with swarm/rock/roam tables. Checkpoints gold-ckpt-NN.lua exist per section;
-gold-ckpt-18-pristine.lua is the post-E4 seed. ROM: ../decprep/Pokemon - Gold
-Version.gbc. Cart source: ../pokegold (cite it in any hand-ported code).
-
-Headless love needs a pty on macOS; wrap every run:
-  perl -e 'alarm 900; exec @ARGV' python3 -c "import pty; pty.spawn(['love','.'])"
-
-Full bot run:  POKEPORT_IDENTITY=<id> POKEPORT_GAME=gold POKEPORT_SPEED=200 \
-  POKEPORT_GOLD_CKPT=1 POKEPORT_GOLD_STALL=20000 POKEPORT_GOLD_LOG=/tmp/b.log \
-  POKEPORT_DRIVER=tests/drivers/gold_bot.lua love .
-Resume a section: POKEPORT_GOLD_RESUME=NN (same identity, prior CKPT=1 run).
-Travel probe: POKEPORT_GOLD_PROBE="MAP_A>MAP_B" with tests/drivers/gold_travel_probe.lua.
-Map graph: luajit tools/goldwalk/mapgraph.lua path|map|reach|audit; regenerate
-tests/drivers/gold/map_regions.lua with `mapgraph.lua graph >` after ANY extractor map
-change, then re-check route region indices.
-Route validation (before any run): luajit tests/gold_route_validate_test.lua and
-luajit tests/gold_flag_names_test.lua.
-Suites: GOLD_CACHE="$HOME/Library/Application Support/LOVE/gold-dev/gold" luajit
-tests/gen2_<name>_test.lua; tiers run_engine/run_modkit/run_tests.
-Reimport after extractor/manifest changes: python3 tools/make_gold_manifest.py, then
-POKEPORT_IMPORT_TRACE=1 POKEPORT_IDENTITY=gold-dev POKEPORT_IMPORT_ROM="../decprep/\
-Pokemon - Gold Version.gbc" POKEPORT_IMPORT_ONLY=1 POKEPORT_FORCE_IMPORT=1 \
-POKEPORT_GAME=gold love .
-
-## Recommended shape of the work
-
-1. Extend tests/drivers/gold/route.lua with sections 19-32 (the row format, ops and
-   evidence rules are documented in the file head and bot.lua). Seed runs from
-   gold-ckpt-18-pristine plus the now-working post-credits CONTINUE. `expect` flags are
-   the only oracles; never make a row load-bearing on a soft-failing map.
-2. Highest-risk multi-map scripted chains first: S.S. Aqua voyage, Machine Part chain,
-   PASS/Magnet Train chain. Each deserves an assertion driver even if bot rows also
-   cover it.
-3. Time-gated beats (S.S. Aqua sailing days, Indigo rival Mon/Wed, Dragon's Den
-   Tue/Thu, Clefairy Monday night, TM03 night gate) need POKEPORT_GOLD_DAY/HOUR pins.
-4. Johto stragglers are folded in below (lighthouse descent, TM08 flake, and the
-   optional gift beats); they ride the same route-extension pass.
-5. Section 32 (beasts) last: it needs long roaming play; trap volatiles and FORCESHINY
-   landed this campaign, so Mean Look + Heavy/Fast Ball plans are now viable.
-
-## Also deferred (deliberate stubs, do not re-flag)
-
-Time Capsule trading, Trainer House CAL2/Mystery Gift visitor, Silver-version import,
-Cable Club link rooms, and Game Boy Printer output are deliberate product-level stubs,
-not campaign work.
-
-## The beats, in walkthrough order
-
-### Runtime coverage ends at the Hall of Fame: no bot row, driver, or human has run any Kanto beat (sections 19-32) or the section 14 Tin Tower/Whirl Islands content
-
-walkthrough section(s) 19,20,21,22,23,24,27,28,29,30,31,14 | missing
-
-One root cause: tests/drivers/gold/route.lua (1264 lines) ends at row 18.20 (settle HALL_OF_FAME, expect EVENT_BEAT_ELITE_FOUR); the campaign covers asm-walk sections 00-18 only and none of the 24/36 gold_* drivers reaches any Kanto map, so sections 19-32 have zero execution proof. Extend route.lua into sections 19-32 and/or add targeted drivers. Per section pair: (s19/20) next rows are the Elm ticket (needs the post-credits spawn fix or a fly detour from Indigo), the ship crossing as far as the docking events, the Surge fight, and a Saffron Gym pad-chain assertion. (s21/22) All 24 route/gym trainers resolve in cache with correct parties: Route 9 six (Edna, Sid, Dean, Sidney, Tim, Heidi); Route 25 seven plus Kevin, whose Nugget-then-battle script 50:488d is hand-shaped (a full bag aborts before the battle, cart behavior); Cerulean's three swimmers; Route 10 South's Jim and Robert (Robert's Quagsire holds a BERRY via TRAINERTYPE_ITEM); Route 8's five; Celadon Gym's five including the twins' shared beat flag. Sight-line engagement is Trainers.sees (proven by the Johto bot); prize money base x level x 4 is Prize.lua; Erika's class item extracts as HYPER_POTION (the walkthrough's 'three Full Restores' is a FAQ error, not a port gap); Gold-only wilds (Mankey line Route 9, Growlithe Routes 7/8) come from the ROM version branch; Route 8's PRZCureBerry fruit tree is a fruittree op (Vm.lua:1218) into Apricorns.lua daily reset. One Kanto smoke-run converts the whole block. (s23/24) Nothing touches Routes 11-19, Fuchsia City/gym, Vermilion Snorlax, Diglett's Cave, Route 2, Pewter; the report's three blocker findings (START menu row, Pokegear card flags, radio persistence) are exactly the UI-plumbing breaks data audits miss: a gold_snorlax_wake.lua that grants the gear and EXPN card the way the game does (setflag 4, setflag 0, setflag 3 through the VM, not by poking save fields), tunes the radio, closes the gear, and talks to the Snorlax would currently fail at three separate steps; gold_cycling_road.lua and gold_fuchsia_gym.lua are the other two cheap proofs (gold_menu_shots.lua:72-73 only ever hand-seeded save fields). (s27/28) Drive first: (1) Cinnabar Blue talk -> disappear -> clearevent 1910 -> Viridian Gym populated -> Blue beaten -> ENGINE_EARTHBADGE set -> VAR_BADGES answers 16 (a break anywhere makes the 16th badge unobtainable and the Mt.

Driver: surf Pallet -> Route 21 -> Cinnabar -> talk to Blue -> Route 20 -> beat Blaine -> fly to Viridian -> beat Blue. (s29/30) No rows for Kanto OAKS_LAB, ROUTE_22, ROUTE_28, SILVER_CAVE_OUTSIDE, or the Union Cave B2F Lapras revisit (route.lua's only Union Cave rows are 03.29/04.g); risk concentrates on composites never run together: the 16-badge Oak visit with ProfOaksPCBoot text chain, the double Cut approach to the Route 28 west strip, surf-to-talk on the drifting SWIM_WANDER Lapras (Lake of Rage Gyarados proves the shape via gold_lake_probe.lua), and the daily-flag consume-and-respawn cycle across a save reload; a targeted gold_lapras_probe driver (clockDay=5, walk in, assert object present, catch, walk out, re-enter, assert gone) plus route extension converts inspected to proven. (s31) All six Silver Cave maps decode (warps, item balls flags 1689-1693, hidden items, SILVER_CAVE_OUTSIDE flypoint callback, PALETTE_DARK on Room 1, grass/water tables including Room 2 water); Flash lifts PALETTE_DARK via Palettes.isDarkness + World flashUsed; Surf/Waterfall live in FieldMoves with the badge table; gen2 ledges landed via Permissions.ledgeFacings / World:tryLedgeJump (the asm-walk's 'ledge hop missing' row is stale, GOLD-NEXT-RUN records the fix); the flypoint is FieldMoves.lua:386 flag 75; but no driver has entered Silver Cave, used Waterfall on Room 2's two bands, hopped Room 1's Escape Rope ledge, or talked to Red (closest: gold_halloffame_shots, gold_hm07_probe which proved Waterfall only at Tohjo Falls). (s14) The bot covers sections 10,11,12,13,16,17,18 and never section 14 (Ho-Oh is optional); untested: the 4F-9F ladder/hop mazes (depend on the recently added ledge-hop and one-way-wall support), the Ecruteak entrance sage scene retarget from Morty's setmapscene, the 1F sage unmasking off EVENT_TEAM_ROCKET_DISBANDED (set on the Gold arm of the Radio Tower boss script), the roof save/reset loop, and the entire Gold-side Whirl Islands dive; needs one probe driver carrying a RAINBOW_WING save up the tower and one diving to the Lugia chamber.

The adversarial re-check ran on the s27/28 sub-claim, tried to refute and could not; its one correction: tests/drivers/gold/flag_names.lua and map_regions.lua DO name the Kanto maps (map_regions even carries CINNABAR/SEAFOAM/VIRIDIAN region graphs, so bot travel there is data-ready) but they are lookup tables, not executed coverage. 'Implemented statically, executed by nobody' matches the project's Roamers/Events:restore failure mode. GOLD-WALK-HANDOFF sections 1 and 4 already document the Johto-only scope.

-The date cutscene at Route 25 cells (42,6)/(42,7) is what clears EVENT_TRAINERS_IN_CERULEAN_GYM 1903 and populates the gym with Misty, three swimmers, and the guide; without it Misty never appears and the Cascade Badge is unreachable. Cache has both coord events with sceneId=1 (scripts 18305/18369) and full scripts 50:4781/50:47c1 (34-row cutscene: heart emote, boyfriend flees, Misty approach movement, clearevent 1903, setscene 0, special 60=RestartMapMusic), armed by gym grunt script 54:4336 row 27 (setmapscene group=7 map=16 scene=1). Engine deps: World:tryCoordScript (World.lua:5006) filters on the map scene id; mapScenes persist on the save (GOLD-INDEX tier note on World:loadPlayerData). CeruleanGymMistyScript 54:438a is in the cache; MISTY trainer 1 party (L42 Golduck, L42 Quagsire, L44 Lapras, L47 Starmie with full movesets) extracts correctly; baseMoney 25 so the 4700G payout follows from Prize.reward.

-
-*Notes:* Doc rating: unverified/blocker, new. Correction embedded in the doc: Misty gives NO TM on the Gold cart, only the badge plus retroactive swimmer beat flags; the walkthrough and the lead's 'TM from Misty' are wrong about the cart, nothing is missing in the port there.

-Copycat (COPYCATS_HOUSE_2F object 1, variable sprite slot 251) talk after the machine part return sets EVENT_MET_COPYCAT_FOUND_OUT_ABOUT_LOST_ITEM 206; Fan Club Clefairy guy (POKEMON_FAN_CLUB object 3, script 59:437b) then gives LOST_ITEM 130 and disappears the doll (flag 1908, correctly NOT in the initial seed; doc evidence line also cites POKEMON_FAN_CLUB object 5 flag 1908); returning it (Copycat branch 61:528b: takeitem 130, setevent 208, clearevent 1907 to re-show her shelf doll, then PASS 134 via 61:529d) yields the PASS. All bytecode in cache (61:5235/61:5270/61:528b); the mimicry gag's variablesprite slot 11 plus special 93 resolves to LoadUsedSpritesGFX (specialOrder[94], Specials.lua:1033); the Copycat's variable sprite slot is seeded through World.initialSprites/findInitialSprites (World.lua:1530, the fix GOLD-INDEX credits for the Copycat existing at all). Flag 1907 is in the initial seed so the shelf doll is hidden until the return; 1906 is seeded so the Saffron station stays empty until power is restored.
-
-*How to prove it:* Driver: after machine-part return, talk to Copycat (assert 206), get LOST_ITEM at the Fan Club (assert doll flag 1908 set), return it (assert 208 set, 1907 cleared, PASS 134 in bag).
-
-*Notes:* Doc rating: unverified/major, new. Correction embedded: the walkthrough's 'Rail Pass then Magnet Train Pass' is one item (PASS) on the cart, not a port gap. Merge-with hint: the s20 entry 'Copycat lost doll quest chain toward the rail PASS' (copycat-doll-pass-s20) describes the same quest from the section-20 audit with slightly different event ids cited (210/201 gate checks there vs 206/208 here).

-For a Gold cart, Lugia needs the SILVER_WING carried in the bag (WhirlIslandLugiaChamberLugiaCallback does checkevent EVENT_FOUGHT_LUGIA then checkitem SILVER_WING), and in Gold the wing comes from the Pewter City gramps (pokegold maps/PewterCity.asm PewterCityGrampsScript: checkver, Silver arm branches away, Gold falls through to verbosegiveitem SILVER_WING + setevent). Verified in cache: PEWTER_CITY object 3 (SPRITE_GRAMPS at 29,17) scriptKey 4d:583e = faceplayer / opentext / checkver / iftrue 4d:585c / checkevent 121 / verbosegiveitem item 71 / setevent 121 / closetext / end, all generic opcodes. The Lugia chamber map, its SPRITE_LUGIA object (scriptKey 47:41a0, eventFlag 1853), and its MAPCALLBACK_OBJECTS callback (47:418c) are in the cache using only implemented machinery. Route bot has no section 14/25 rows (grep 'id = "1[0-9]' shows 10,11,12,13,16,17,18). One mechanical gap on the dive path: the waterfall forced-down item, reported separately in the doc.
-
-*How to prove it:* Driver or bot rows: reach Pewter in Gold, talk to the gramps (assert SILVER_WING item 71 given, event 121 set), then the full Whirl Islands dive to the Lugia chamber.

ENGINE_FLYPOINT_VERMILION comes from MAPCALLBACK_NEWMAP on both VERMILION_PORT and VERMILION_CITY (setflag 57); the port's fly table carries the matching row (FieldMoves.lua:392) and World:runMapCallback has a live call site (World.lua:5659 plus the MAPCALLBACK_OBJECTS call in setMap). Fly deliberately stays region-locked exactly like the cart (FieldMoves.flyPoints, FieldMoves.lua:442: Kanto page only after SPAWN_INDIGO, no cross-region fly, verified against pokegold engine/pokegear/pokegear.asm .KantoFlyMap). Kanto music extracted: audio.lua songs has 92 entries, musicOrder includes Music_VermilionCity and Music_ViridianCity (musicOrder[63]=Music_VermilionCity), mapSongs carries all 362 map rows.

The engine mechanism exists and reads correct: pads are COLL_WARP_PANEL 0x7c, an immediate warp (Permissions.lua:311); World:takeWarp (World.lua:6022-6040) handles a destination equal to the current map through setMap; warpCooldown keyed on the landing cell (World.lua:6135 set, 6217-6222, 6240 suppression check) stops the landing pad from re-firing until the player steps off, exactly what a pad-to-pad maze needs. But the asm-walk's own port-coverage table flags that no driver has ever exercised a same-map warp chain, and no Kanto run exists. If this breaks, Sabrina is unreachable and the 10th badge (and eventually Red's gate) is lost.

-### Celadon side items: TM03 Curse night gate, Leftovers trash can, hidden PP Up (plus Berserk Gene, Route 9 Ether, Route 25 Potion) never run
-
-walkthrough section(s) 22 | unverified
-
-TM03 Curse: roof house pharmacist script 5e:5083 in cache with checktime mask 4 (NITE) at row 7; the Vm checktime opcode (Vm.lua:788) maps NITE to bit 4 off World:timeOfDayId, so the night-only gate should behave; the give branch 5e:509a is guarded by EVENT_GOT_TM03_CURSE 218. Leftovers: CeladonCafeTrashcan bg event at (7,1) key 5e:648c present, plain giveitem bytecode with the flag only set on success so a full pack retries, exactly the cart. Hidden PP Up at Celadon (37,21): BGEVENT_ITEM row present, handled by HiddenItems (fixed PP_UP; the walkthrough's 'random PP Up' is wrong on the cart too). Berserk Gene at Cerulean (2,12), hidden Ether Route 9 (10,5), and hidden Potion Route 25 (4,5) likewise extract. All generic and statically sound, none ever run.
-
-*How to prove it:* Kanto run collecting each: night visit for TM03 (checktime NITE), cafe trash can Leftovers with full-pack retry, hidden-item picks via HiddenItems.
-
-*Notes:* Doc rating: unverified/minor, new. Correction embedded: the PP Up is fixed, not random, on the cart.

-### Mt. Moon Square Clefairy dance (Monday night) + hidden Moon Stone + Rock Smash rock: all dependencies present, sequence never executed
-
-walkthrough section(s) 26 | unverified
-
-Coord event at (7,11) scene 0 runs 5b:676a, whose 45 rows extract completely: checkflag 87 (ENGINE_MT_MOON_SQUARE_CLEFAIRY), readvar var 11 (VAR_WEEKDAY, real in the port) ifnotequal 1 (MONDAY), checktime NITE, then the appear/follow/applymovement/cry/showemote dance, clearevent 236 (the hidden Moon Stone flag) and setflag 87. Both callbacks extracted (type 5 NEWMAP 5b:6763 re-hides the stone on entry; type 2 OBJECTS 5b:6767 hides the rock). The rock object (SPRITE_ROCK at 7,7, scriptKey 5b:67ee = jumpstd SmashRockScript) resolves to the real SmashRock/AskRockSmash bodies GOLD-INDEX.md:377-382 documents; follow/stopfollow are implemented (Vm.lua:1009,1026). Flag semantics match the cart: ENGINE_MT_MOON_SQUARE_CLEFAIRY lives in wDailyFlags2 (pokegold constants/engine_flags.asm:105-106) and the port clears id 87 in Apricorns.DAILY_ENGINE_FLAGS, so the dance is once per day, i.e. once per Monday night. Unproven in-game: (a) whether the appeared rock correctly blocks/receives the A press on the Moon Stone tile at (7,7) and Rock Smash then exposes the hidden item in the same visit, and (b) the full follow-chain animation. The stubbed RockMonEncounter (CallAsm STUB_ROWS) does NOT affect this rock: MOUNT_MOON_SQUARE is not in the cart's RockMonMaps (pokegold data/wild/treemon_maps.asm:43-48), so no encounter roll is owed here.
-
-*How to prove it:* Driver: force clockDay=MONDAY clockHour=NITE, walk to (7,11), watch the dance, smash the rock, take the Moon Stone.

-### Rival re-encounters after Mt Moon (Indigo Plateau Mon/Wed rematch, Dragon's Den Tue/Thu cameo) never run
-
-walkthrough section(s) 26 | unverified
-
-Both beats are pure extracted content keyed on EVENT_BEAT_RIVAL_IN_MT_MOON (set by the implemented Mt Moon script) and VAR_WEEKDAY (real in the port; World:readVar VAR_WEEKDAY at World.lua:1289): the cache carries INDIGO_PLATEAU_POKECENTER_1F's NEWMAP callback 5a:48b6 (23 rows of setmapscene/clearevent resets) plus its two coord events, and DRAGONS_DEN_B1F's callback 47:44e1 (checkevent 793 -> disappear object 4). The daily rematch flag ENGINE_INDIGO_PLATEAU_RIVAL_FIGHT (id 92) is in Apricorns.DAILY_ENGINE_FLAGS so it clears on the daily rollover. The rematch parties RIVAL2 members 4-6 (L45-50 with CROBAT) are in trainers.lua. Nothing looks missing, but the coord-event choreography in the Pokecenter (rival walks in as you leave) is the kind of scene worth a driver before trusting; filed unverified rather than implemented for that reason.
-
-*How to prove it:* Driver: set EVENT_BEAT_RIVAL_IN_MT_MOON via the Mt Moon fight, force weekday Monday/Wednesday, enter the Indigo lobby and assert the rematch triggers; force Tuesday/Thursday and assert the Dragon's Den object 4 state.
-
-*Notes:* Doc rating: unverified/minor, new. Merge-with hint: overlaps indigo-lobby-rival-rematch (s18), the same Indigo Plateau rematch filed from the section-18 audit; that filing cites World:weekday at World.lua:1247 and scriptKeys 5a:48ff/5a:4940.
-
-
-### Indigo lobby rival rematch (Monday/Wednesday, RIVAL2, post Mt. Moon) armed on tiles the walkthrough crosses, never run
-
-walkthrough section(s) 18 | unverified
-
-Not in the walkthrough text but armed on the lobby tiles it crosses: coord events at (16,4)/(17,4) run PlateauRivalBattle1/2 (cache scriptKeys 5a:48ff/5a:4940), which fight the RIVAL2 second-tier party when EVENT_BEAT_RIVAL_IN_MT_MOON is set, ENGINE_INDIGO_PLATEAU_RIVAL_FIGHT is clear, and VAR_WEEKDAY is Monday or Wednesday (pokegold maps/IndigoPlateauPokecenter1F.asm). Every dependency exists: coord events and scripts extracted, VAR_WEEKDAY answers the real weekday (World:weekday, World.lua:1247), the daily engine flag is registered for midnight reset (Apricorns.lua:88, id 92 ENGINE_INDIGO_PLATEAU_RIVAL_FIGHT), and RIVAL2 parties 4-6 (SNEASEL/45, CROBAT/48, MAGNETON/45, GENGAR/46, ALAKAZAM/46, starter/50) are in the trainers cache. But the gate flag EVENT_BEAT_RIVAL_IN_MT_MOON is Kanto content no run has ever set.
-
-*How to prove it:* Should be picked up when section 26 is audited/run: same driver as rival-rematch-mtmoon, entering the lobby on Monday/Wednesday with the Mt Moon flag set and asserting the coord-event battle fires.
-
-*Notes:* Doc rating: unverified/minor, new. Merge-with hint: same beat as rival-rematch-mtmoon (s26); kept separate because the doc filed both headings. Line-cite difference between filings: World.lua:1247 (weekday) here vs World.lua:1289 (readVar VAR_WEEKDAY) there.

-### Lighthouse descent and swim to Cianwood (route rows 08.50/08.51) never walked; collision data matches the cart, blame points at the bot's region graph
-
-walkthrough section(s) 08 | unverified
-
-The route bot has never completed the descent from Jasmine to Route 40, so the Surf crossing, all fourteen Route 40/41 swimmers, and Cianwood arrival are engine-unwalked (runs reach section 08+ by teleport; run 28 still failed rows 08.50/08.51). The handoff narrows it to the 3F seven-cell pocket: warps 8/9 at (8,3)/(9,3) 'do not take' when stood on. Verified in the current cache: OLIVINE_LIGHTHOUSE_3F (8,3)/(9,3) decode to COLL_FLOOR 0x00, and pokegold data/tilesets/lighthouse_collision.asm block $27 is FLOOR,FLOOR,FLOOR,FLOOR, so those two warp rows are one-way landing anchors for the 4F pits at (8,3)/(9,3) (which decode to COLL_PIT 0x60) and never fire on the cart either. The pocket's real exit is warp 3, the staircase at (9,5), which decodes to 0x72 and does fire ((13,3) also 0x72). Fix shape: correct the bot's region graph, which treats landing-anchor warp coordinates as exits (the exact trap GOLD-WALK-HANDOFF.md:593 documents), not the engine; a human following the walkthrough (drop beside Connie, fight Terrell, take the Ether, head up the stairs) uses the (9,5) staircase and should be fine.
-
-*How to prove it:* Something must walk 6F down to CIANWOOD_CITY in the engine (bot rows 08.50/08.51 passing, or a driver doing the descent and the Route 40/41 Surf crossing); until then the second half of section 08 stays a beat-completeness check rather than a proven path.
-
-*Notes:* Doc rating: unverified/major, already named in the ledger. The doc's own re-check corrected the suspicion of an engine defect: the cache collision matches the cart exactly, so the failing rows indict the bot's region graph, not the engine or the warp data.

-### TM08 Rock Smash give (route row 06.21) flaky across runs; ledger contradicts itself and the failure is unresolved
-
-walkthrough section(s) 06 | unverified
-
-The Route 36 fisher gives TM08 after EVENT_FOUGHT_SUDOWOODO (Route36RockSmashGuyScript, generic extracted bytecode with verbosegiveitem guarded by iffalse .NoRoomForTM). The ledger contradicts itself across runs: GOLD-WALK-HANDOFF section 8 says 'Everything before it now passes on merit: Sudowoodo, TM08, the ROCK SMASH teach', but run 28's failure table lists '06.21 ROUTE_36 EVENT_GOT_TM08_ROCK_SMASH not set' while the Sudowoodo row itself passed. Plausible causes: full TM pocket taking the iffalse arm, or the bot failing to stand adjacent. The script path is generic and the same give shape works everywhere else, so this is most likely route flake, but it is unresolved in the latest continuous run and TM08 gates all Rock Smash content downstream (Burned Tower rocks, Route 40/Cianwood rock items).
-
-*How to prove it:* Re-run route row 06.21 in a continuous run and assert EVENT_GOT_TM08_ROCK_SMASH gets set; instrument for TM-pocket fullness and adjacency to distinguish the two suspected causes.
-
-*Notes:* Doc rating: unverified/minor, already named in the ledger. Not given severity unverified-risk because the problem is a reproduced-once run failure (a live flake), not purely never-executed content.

-### New Bark rival push scene (talk to rival by the lab) unproven; low risk, zero coverage
-
-walkthrough section(s) 00 | unverified
-
-Walkthrough: 'If you talk to him, he'll push you out of the way.' NewBarkTownRivalScript is optional, repeatable (sets no flag) and uses follow PLAYER, applymovement with turn_head/step/fix_facing/jump_step, and SFX_TACKLE. Every opcode involved is implemented (follow/stopfollow in the VM, jump_step in Movement.lua which the ledge fixes exercised), and the sibling teacher-drag scene has a dedicated driver (tests/drivers/gold_teacher_scene.lua), but no driver or test touches this specific scene and the route bot never talks to optional NPCs. Cache maps.lua NEW_BARK_TOWN objects include the rival with a scriptKey and eventFlag.
-
-*How to prove it:* A short driver that talks to the rival by the lab and observes the push movement chain, mirroring gold_teacher_scene.lua.

-### Kiyo battle and Tyrogue gift (Mount Mortar B1F): fully wired, never exercised by any driver or bot run
-
-walkthrough section(s) 15 | unverified
-
-The game's only Tyrogue. Cache scripts['46:5eec'] holds all 29 rows of MountMortarB1FKiyoScript (checkevent 97 / 1193, winlosstext, loadtrainer class BLACKBELT_T member 6, startbattle, reloadmapafterbattle, setevent 1193, readvar var=1 VAR_PARTYCOUNT, ifequal 6, givepoke species 236 level 10, setevent 97); trainers cache has BLACKBELT_T[6] KIYO = L34 HITMONLEE + L34 HITMONCHAN (KIYO object at 13,4 with scriptKey 46:5eec); readvar VAR_PARTYCOUNT is a real read (World.lua:1271); givepoke is implemented at Vm.lua:443. The full dependency chain has never run: Surf across the 1F Outside lake, the in-cave Waterfall climb to warp 4 at (17,5), the 2F/1F-inside/B1F warp descent, the battle, and the gift. The waterfall climb mechanic itself is bot-verified only at Tohjo Falls; route.lua contains no MORTAR/KIYO/DARK_CAVE rows.
-
-*How to prove it:* A Mount Mortar driver: Surf the outside lake, Waterfall to warp 4 (17,5), descend to B1F, beat Kiyo, assert Tyrogue (species 236, L10) given with a party of <6 and events 97/1193 set.
-
-*Notes:* Doc rating: unverified/major, new. Correction embedded: GOLD-INDEX's claim that only VAR_WEEKDAY and VAR_FACING answer readvar is STALE; World.lua:1265-1330 now answers essentially every VAR_*.

-### Blackglasses pharmacist in Dark Cave Blackthorn entrance extracted exactly, never run (same for TM13 Snore and Revive balls)
-
-walkthrough section(s) 15 | unverified
-
-The script is fully extracted (cache scripts['47:436c'], 13 rows matching pokegold maps/DarkCaveBlackthornEntrance.asm exactly: checkevent / verbosegiveitem / iffalse pack-full arm / setevent), the spinning NPC object (SPRITE_PHARMACIST) is in the cache at (7,3) with that scriptKey, and verbosegiveitem is implemented in the VM. Reaching him also needs Flash plus Surf inside the cave, both implemented. The same unverified state covers the TM13 Snore and Revive item balls beside him (item ball arm is implemented and tested). No driver enters Dark Cave and the bot route bypasses it (grep DARK_CAVE in route.lua is empty).
-
-*How to prove it:* A Dark Cave driver: Flash + Surf to the Blackthorn entrance, talk to the pharmacist (assert Blackglasses given), pick up TM13 Snore and the Revives.

-### Master Ball from Elm after eighth badge: route rows exist but optional, no run log confirms the event ever set
-
-walkthrough section(s) 16 | unverified
-
-ProfElmScript's ElmCheckMasterBall gate is checkflag ENGINE_RISINGBADGE then verbosegiveitem MASTER_BALL then setevent EVENT_GOT_MASTER_BALL_FROM_ELM (pokegold maps/ElmsLab.asm:57-61). All generic extracted bytecode; checkflag over ENGINE_* badges works since the badge-store fix (GOLD-WALK-HANDOFF.md:502, badges routed into save.player.badges). The route bot has rows 16.24/16.24b for this beat but both are marked optional = true, and no run log or handoff note confirms EVENT_GOT_MASTER_BALL_FROM_ELM was ever actually set in a live run (no MASTER hits in GOLD-NEXT-RUN.md run logs). A full bag silently skips the setevent (verbosegiveitem iffalse), same as the cart.
-
-*How to prove it:* Make route rows 16.24/16.24b non-optional (or run them) and assert EVENT_GOT_MASTER_BALL_FROM_ELM set with bag space available.

-
-walkthrough section(s) 16 | unverified
-
-The gating special FindPartyMonThatSpeciesYourTrainerID is a real handler with the own-OT check (Specials.lua:1134), and the phone-call prerequisite is NOT required: pokegold maps/ElmsLab.asm ElmCheckTogepiEgg -> EVENT_TOGEPI_HATCHED -> ElmEggHatchedScript re-runs the same species scan, so a hatched Togepi in the party is sufficient (maps/ElmsLab.asm:62-95, engine/phone/scripts/elm.asm:46). Egg hatching has a driver (tests/drivers/gold_egg_hatch.lua) and PC withdraw exists (BoxMenu.lua / PcMenu.lua). The full chain (hatch with your OT, withdraw, talk, EVENT_SHOWED_TOGEPI_TO_ELM, verbosegiveitem EVERSTONE) has never run end to end. The .egghatched arm of ElmPhoneCalleeScript (sets EVENT_TOLD_ELM_ABOUT_TOGEPI_OVER_THE_PHONE) lives in the bank $41 callee scripts and only matters for the alternate entry path. No route row exists for the Everstone.
-

-The granny's script is extracted (cache scripts['60:6352'], 9 rows: checkevent, special id 88, ifgreater, sjump into the loyal/disloyal arms) and special id 88 resolves through constants.specialOrder with the VM's order[id+1] rule (Vm.lua:1773) to specialOrder[89] = GetFirstPokemonHappiness, a real handler at Specials.lua:1506 reading the first non-egg party member. The cart gate is happiness >= 150 on the FIRST party slot (ifgreater 150-1), not 'one of your Pokemon'. Happiness accrues via Happiness.lua stepped from StepEvents. No driver or bot row enters ROUTE_27_SANDSTORM_HOUSE.

-### Route 27 whirlpool island (Bird Keeper Jose, TM22 Solarbeam, Rare Candy) and Tohjo Falls Moon Stone never run; whirlpool mechanic only proven on Route 41
-
-walkthrough section(s) 16 | unverified
-
-The whirlpool mechanic is implemented and driver-verified, but on Route 41, not here: tests/drivers/gold_water_moves.lua:105-124 clears a real whirlpool block with GLACIERBADGE gating and asserts the block replacement. The Route 27 island content is all in the cache (TM_SOLARBEAM ball at (60,12) item id 213 with event flag, Rare Candy ball at (53,12), BIRD_KEEPER[14] JOSE = L35 FARFETCH_D with phone contact rows; maps.ROUTE_27 objects rows 6-8) and the item ball arm is implemented, but the bot route crosses Route 27 only via Tohjo Falls and never surfs south past Gilbert (route rows 16.42-16.43 skip the south water), so this specific whirlpool, the Jose fight, and the TM22 pickup have never run. Same for the Tohjo Falls MOON_STONE ball at (2,6) (maps.TOHJO_FALLS object 1), which the walkthrough itself never mentions.
-
-*How to prove it:* Driver or route rows: surf south past Gilbert, clear the Route 27 whirlpool, fight Jose, collect TM22 and the Rare Candy; separately pick up the Tohjo Falls Moon Stone.

Unconditional and repeatable like the cart. No driver or bot row ever enters ROUTE_26_HEAL_HOUSE; the bot route's Route 26 leg is a single travel row straight to the gate.

-### Victory Road item pickups (TM26 Earthquake pit, Full Restore shelf, Max Revive, Full Heal, X Special, two hidden items) never exercised

-The walkthrough collects five Poke Ball items (TM26 Earthquake via the one-way pit at (0,11), Full Restore on the ledge shelf via the (17,19) ladder, Max Revive and Full Heal in the entrance region, X Special on the HOP_LEFT column) plus two hidden items (Max Potion at (3,29), Full Heal at (3,65)). All pieces exist: cache maps.VICTORY_ROAD carries 6 objects (5 with itemball item/qty payloads), 2 bgEvents with hiddenItem tables, 10 warps, 2 coord events; World:interact consumes obj.itemball (World.lua:5483-5490, an earlier bot-found fix); HiddenItems handles BGEVENT_ITEM; Permissions models the COLL_PIT one-way warp, the six ladders, ledge hops (isLedge/ledgeFacings, Gold's own direction order where $a0 is HOP_RIGHT), and COLL_UP_WALL side walls (Permissions.lua:170-260 LEDGE_FACINGS/SIDE_BLOCKS/NEIGHBOR_ARM), with a test section at tests/gen2_world_test.lua:2936. But nothing has walked these routes: the bot's section 17 is only travel/walk rows 17.2, 17.11, 17.15 (no pickup rows), so the pit drop, the two HOP exits from the TM pocket, the HOP_DOWN off the shelf, and the X Special ball sitting ON a HOP_LEFT tile (the one placement the asm-walk flags as needing hardware confirmation) are all unproven end to end.
-
-*How to prove it:* Driver or route rows through Victory Road collecting all five balls and both hidden items, specifically exercising the (0,11) pit drop, the (17,19) ladder shelf with HOP_DOWN exit, the two HOP exits from the TM pocket, and interaction with the X Special ball on its HOP_LEFT tile.

+#
+# The launcher uses SHDIR-relative paths and bundles the LÖVE 11.5 aarch64
+# runtime so the device does not need a separate runtime download on first launch.
+#
+# Usage:
+#   ./build-linux-arm-sbc.sh [--version X.Y.Z]
+#   GEN1RECOMP_SOURCE_DIR="$PWD" ./build-linux-arm-sbc.sh --version X.Y.Z

+#   dist/linux-arm-sbc/gen1recomp-sbc-portmaster.zip
+#
+# Install on device:
+#   1. Install PortMaster for the handheld firmware.
+#   2. Unzip into the device's PortMaster ports folder so you have:
+#        Roms/Ports (PORTS)/gen1recomp-sbc.sh

+## gen1recomp-sbc (Linux ARM SBC / PortMaster)
+
+Native LÖVE 11.5 aarch64 PortMaster port of gen1recomp for compatible Linux ARM SBC handhelds, including H700-class devices. This pack was built from source release **__SOURCE_TAG__**.
+
+### Install
+
+1. Install PortMaster for your handheld firmware.
+2. Unzip so `gen1recomp-sbc.sh` and the `gen1recomp-sbc/` folder are siblings in the device's PortMaster ports directory.
+3. Copy a legal US Pokémon Red or Blue `.gb` into `gen1recomp-sbc/lovegame/`.
+4. Refresh the launcher and launch **gen1recomp-sbc** from Ports.
+
+### Controls
+
+| Input | Action |
+|--|--|
+| D-pad | Move cursor |
+| A | Click |
+| L1 / R1 | Switch tabs |
+| Start / Select | Play or choose ROM |
+
+Controls use the normal PortMaster / SDL pad map. Device-specific power/suspend behavior is supplied by the firmware and PortMaster runtime.
+
+### First run
+
+Put the `.gb` in `lovegame/`, then press **Choose ROM**. After import, the ROM-derived cache and saves stay beside the game (`portable.txt`).
+
+### Thanks
+
+LÖVE runtime binaries from [PortMaster](https://portmaster.games/). PortMaster device support and runtime integration are maintained by the PortMaster team.

-# Behavior porting notes
-
-What was ported from pokered's engine code and where it came from.
-
-## Overworld
-
- **Collision rule** (`home/overworld.asm` tile-in-front checks): a 16x16
-  cell is passable when its bottom-left 8x8 tile is in the tileset's
-  `coll_tiles` list. Verified against Pallet Town's fences/houses/water
-  and Oak's Lab furniture.
- **Warp activation** (`home/overworld.asm` CheckWarpsNoCollision /
-  ExtraWarpCheck): a warp fires when arriving on a warp whose standing
-  tile is in the tileset's door or warp tile list, or when standing on a
-  warp and walking off the map edge (interior exit mats). Both paths are
-  data-driven from `door_tile_ids.asm` / `warp_tile_ids.asm`.
- **LAST_MAP warps** return to the remembered outdoor map/position, like
-  `wLastMap`.
- **Connections** (`map_header` connection directives): crossing an edge
-  places the player at `destCoord = curCoord - offset*2` cells on the
-  destination's opposite edge.
- **Movement**: tile-by-tile, 1 px/frame at 60 fps (16 frames per step),
-  tap-to-turn without stepping, hold-to-walk, input locked mid-step.
- **Wild encounters** (`engine/battle/wild_encounters.asm`): per grass
-  step, encounter iff `rand(0..255) < rate`; slot picked via the
-  cumulative buckets 51/102/141/166/191/216/229/242/253/256.
- **Initial object visibility** from `toggleable_objects.asm` (e.g. Oak
-  hidden in his lab), with `show_object`/`hide_object` script commands
-  persisting to the save like the missable-object bits.
-
-## Pokémon math (`engine/pokemon/calc_stats.asm`, `experience.asm`)
-
- `stat = floor(((base + DV)*2 + floor(sqrt(statExp)/4)) * L / 100) + 5`
-  (HP: `+ L + 10`); HP DV from the low bits of the other four DVs.
- Growth curves use the exact cubic coefficients (MEDIUM_SLOW =
-  1.2n^3 - 15n^2 + 100n - 140, etc).
- Exp gain = `floor(baseExp * level / 7)` (x1.5 for trainer battles);
-  defeated species' base stats accumulate as stat experience.
-
-## Battle core (`engine/battle/core.asm`)
-
- Damage: `floor(floor(2L(x2 crit)/5 + 2) * power * atk / def / 50)`
-  capped at 997, `+2`, STAB x1.5, per-matchup type multipliers applied
-  sequentially (x10 fixed point), then `rand(217..255)/255` when
-  damage > 1.
- Critical hits: `rand(0..255) < baseSpeed/2` (x4 for Karate Chop, Razor
-  Leaf, Crabhammer, Slash, capped 255); crits double level and ignore
-  stat stages (gen1_faithful ruleset).
- Accuracy: `rand(0..255) < floor(acc*255/100)` after accuracy/evasion
-  stages,  including the 1/256 miss at 100% accuracy (toggleable via the
-  `modern_clean` ruleset).
- Stat stages use the 25/28/33/40/50/66/100/150/.../400 multiplier table
-  (`data/battle/stat_modifiers.asm`).
- Physical/special split by type (special = Water/Grass/Fire/Ice/
-  Electric/Psychic/Dragon).
- Status: paralysis speed/4 and 25% full para, burn halves physical
-  attack, poison/burn residual = maxHP/16, sleep 1-7 turns waking on the
-  lost turn, freeze permanent (as in Gen 1).
- Turn order: effective speed, coin-flip ties; Quick Attack first,
-  Counter last (Gen 1's only priorities).
- Run formula (`TryRunningFromBattle`): always escape if faster,
-  otherwise `floor(pSpd*32 / (eSpd/4)) + 30*attempts` vs `rand(0..255)`.
- Catching (`ItemUseBall`): ball-specific rand ranges (255/200/150),
-  status bonus 25/12, second roll `floor(maxHP*255/ballFactor) /
-  floor(HP/4)` capped 255.
- Prize money: class base money x last defeated mon's level
-  (`pic_pointers_money.asm`).
-
-## Battle move effects (engine/battle/core.asm, move_effects/*)
-
- Mimic via Metronome (effects.asm:1203-1273): MimicEffect's
-  .letPlayerChooseMove branch snapshots wCurrentMenuItem before the
-  copy-picker menu opens and restores it afterward as the write index
-  into wBattleMonMoves. Since SelectMenuItem always writes
-  wCurrentMenuItem/wPlayerMoveListIndex together at the FIGHT-menu
-  confirm and nothing (including MetronomePickMove) touches either
-  variable during mid-move resolution, the reused value is always the
-  calling move's own slot,  BattleState.lua's applyMimic fallback uses
-  self.moveIndex, frozen the same way, so a called Mimic (e.g. from
-  METRONOME in slot 3) overwrites the calling move's own slot, keeping
-  its PP, matching the Gen 1 quirk exactly.
- Multi-hit distribution 2/2/2/3/3/3/4/5 over rand(0..7); all hits reuse
-  the first damage roll (faithful).
- Recoil = damage/4 (Struggle /2); drain/Dream Eater heal = damage/2;
-  Dream Eater requires sleep.
- Fixed damage: SonicBoom 20, Dragon Rage 40, Seismic Toss/Night Shade =
-  level, Psywave rand(1 .. 1.5xlevel-1).
- OHKO deals 65535, fails against faster targets; Swift skips accuracy;
-  Jump Kick crash = 1 damage on miss; Explosion halves defense and
-  faints the user even on a miss; Hyper Beam skips recharge if it KOs.
- Charge moves (incl. Fly's invulnerable turn), trapping moves locking
-  the victim out of its turns, Thrash's 3-4 turn lock ending in
-  confusion, Bide's 2-3 turn store-and-double, Rage's permanent lock
-  with attack-up on being hit, Counter/Quick Attack priority.
- Side-effect chances: 26/256 (10%), 77/256 (30%), stat-down side
-  effects 85/256; Twineedle 20% poison.
- Substitute costs 1/4 max HP, absorbs damage, blocks status/stat/side
-  effects; screens double effective defense (bypassed by crits); Focus
-  Energy keeps the Gen 1 quarter-rate bug under gen1_faithful.
- Status: sleep 1-7 turns (wake turn is lost), freeze permanent, burn
-  halves physical attack, paralysis speed/4 + 25% full para, Toxic's
-  rising counter, Leech Seed transfer, confusion 2-5 turns with 50%
-  40-power typeless self-hit.
- Trainer Pokémon use fixed DVs 9/8/8/8 (TrainerAI.asm convention).
-
-## Items (engine/items/item_effects.asm)
-
- Potion family 20/50/200/full; drinks 50/60/80; status heals per item;
-  Revive half HP; Rare Candy = exact next-level exp with HP delta kept;
-  evolution stones use the extracted evos data; TMs single-use / HMs
-  reusable, gated by the species' real tmhm list; Repel 100/200/250
-  steps blocking wilds below the lead's level; Escape Rope returns to
-  the last heal point.
- Snorlax (Route 12/16) only wakes via `ItemUsePokeFlute` (item-use
-  menu, adjacent to it, not yet beaten),  talking to it with the POKé
-  FLUTE merely in the bag has no effect (`engine/items/item_effects.asm`,
-  `scripts/Route12.asm`/`Route16.asm`).
- Mart inventories come from the script_mart lists per clerk; selling
-  pays half price; TM prices from tm_prices.asm.
-
-## Overworld field systems
-
- Ledges from ledge_tiles.asm (facing + standing tile + ledge tile +
-  input direction -> two-cell hop).
- Counter talk-through uses the tileset's counter tiles
-  (tileset_headers.asm), which is how mart clerks and nurses work.
- Trainer sight (`home/trainers.asm` CheckFightingMapTrainers +
-  `engine/overworld/trainer_sight.asm`): extracted per-trainer range,
-  inclusive tiles along the facing line; detection runs only on
-  tile-aligned frames, before input handling, so on detection the d-pad
-  is dead (wJoyIgnore) and the player freezes on the spotted tile; the
-  "!" holds 60 frames (EmotionBubble), then the trainer walks
-  distance−1 steps to the adjacent tile (none if already adjacent) and
-  uses the real battle/won/after dialogue from the trainer headers.
-  Sight is a pure screen-coordinate comparison with no line-of-sight
-  obstruction check (TrainerEngage / CheckSpriteCanSeePlayer): an
-  aligned in-range trainer engages through interposed NPCs and
-  unwalkable tiles, and the walk-up (TrainerWalkUpToPlayer, a fixed
-  distance−1 MoveSprite_ script) has no collision either, so the
-  trainer simply walks/overlaps through anything on the line,  as OAM
-  sprites overlap on hardware.
- Elevator rides (`engine/overworld/elevator.asm` ShakeElevator →
-  `src/world/ElevatorShake.lua`): choosing a floor stops the music,
-  bounces the BG scroll ±1 px around rest for 100 two-frame cycles with
-  SFX_COLLISION retriggered every cycle, restores the scroll, plays
-  SFX_SAFARI_ZONE_PA to completion, and restarts the map theme before
-  the floor warp. Lead-in delays kept per script: 9 frames of Delay3s
-  inside ShakeElevator (Celadon farjps in), 12 with the Silph/Rocket
-  scripts' extra Delay3. The offset applies to the BG layer only, 
-  sprites are OAM and stay put. After the ride the port no longer
-  jump-cuts: choosing a floor rewrites the car's own exit-warp entries
-  to that floor (`engine/events/elevator.asm` DisplayElevatorFloorMenu
-  .UpdateWarp, per scripts/SilphCoElevator.asm /
-  CeladonMartElevator.asm / RocketHideoutElevator.asm), then the player
-  is walked out through the doorway onto that warp (ow:scriptMove →
-  ow:takeWarp), like the original.
- Field-move gates (engine/overworld/field_move_messages.asm +
-  start_sub_menus.asm): IsSurfingAllowed ported exactly,  SURF refuses
-  with _CyclingIsFunText while the Cycling Road's BIT_ALWAYS_ON_BIKE is
-  armed (save.forcedBike: set on the Route 16/18 forced-bike tiles,
-  cleared by the gates, Fly, dungeon/blackout warps; the forced mount
-  itself is silent, as in CheckForceBikeOrSurf) and with
-  _CurrentTooFastText on Seafoam B4F's stairs square (7,11) until both
-  EVENT_SEAFOAM4 boulders are down. Re-selecting SURF while surfing is
-  ItemUseSurfboard's dismount attempt: steps ashore silently if the
-  facing tile is land-passable and unoccupied, else "There's no place
-  to get off!",  and the menu closes either way (wActionResult stays 1).
-  STRENGTH's first page auto-advances after the cry + Delay3 (no
-  prompt); "can move boulders." prompts. The GBPalWhiteOutWithDelay3
-  white blink plays on every .goBackToMap closer: Strength, surf
-  mount/dismount/no-place, Flash (after its text), and Dig/Teleport
-  (Cut closes without a blink, per the asm).
- Wild slot table + rate per map; water encounter tables used while
-  surfing.
- Cut-tree block swaps from cut_tree_blocks.asm; surfable tilesets from
-  water_tilesets.asm (water tile $14, plus $32 on SHIP_PORT).
-
-## Story events (data/scripts/story.lua and friends)
-
- Every hand-ported script cites its scripts/*.asm source and reuses the
-  real extracted text and event-flag names.
- Custom flag names (audited equivalent): three port-internal flag
-  families have no pokered EVENT constant but mirror the original's
-  state exactly. EVENT_TRADED_* are per-trade names for
-  wCompletedInGameTradeFlags bits (engine/events/in_game_trades.asm:
-  FLAG_TEST before the offer → after-trade text, FLAG_SET on completion;
-  dialogset text families, party-menu pick, the received mon joins the
-  end of the party, ConnectCable→anim→TradedFor→Thanks all ported).
-  EVENT_GOT_EEVEE is bookkeeping alongside the real guard,  the hidden
-  ball object (scripts/CeladonMansionRoofHouse.asm HideObject, ≡
-  save.objectToggles),  and self-heals older saves; a full party+box
-  keeps the ball claimable (_BoxIsFullText). EVENT_BEAT_SS_ANNE_RIVAL
-  stands in for scripts/SSAnne2F.asm's saved wSSAnne2FCurScript NOOP
-  progression, including the lose-and-retrigger path (flag only set on
-  victory). Names are kept for save compatibility. Coverage:
-  tests/parity_trade_gift.lua.
- The Pallet Town intro follows pokered exactly: the trigger is
-  PalletTownDefaultScript's wYCoord==1 check, Oak appears at (8,5) and
-  takes FindPathToPlayer's zigzag to one tile below the player, and the
-  escort is RLEList_ProfOakWalkToLab against the reverse-order playback
-  of RLEList_PlayerWalkToLab (the 17th simulated press is eaten by the
-  door-warp frame), followed by the OaksLab walk-in and choose-mon
-  exchange with map music deferred like BIT_NO_MAP_MUSIC. Oak's speech
-  ends with the real shrink: RedPicFront collapses through the extracted
-  ShrinkPic1/ShrinkPic2 into the overworld walking sprite on
-  OakSpeech.asm's frame timings (SFX_SHRINK, 4/4/20/50-frame beats, fade
-  to white), with the closing text box held on screen. The escort's
-  scripted steps run 16 frames/tile (chained single-tile scriptMoves
-  start back-to-back, no idle frame); Oak marches in place on the door
-  mat for RLEList_ProfOakWalkToLab's trailing NPC_CHANGE_FACING beat
-  (movement.asm ChangeFacingDirection → zero-delta TryWalking); the "!"
-  EmotionBubble overlaps the still-shown "Hey! Wait!" box
-  (PalletTownOakText prints without a button wait, then DelayFrames 10 →
-  EmotionBubble before the box clears); and the shrink beat ramps the
-  music to silence over ~70 frames (wAudioFadeOutControl = 10;
-  home/fade_audio.asm FadeOutAudio steps rAUDVOL 7→0) rather than
-  hard-stopping.
- The 12 disguised static wild battles (Power Plant Voltorb/Electrode +
-  Zapdos, Articuno, Moltres, Mewtwo) follow TalkToTrainer/
-  EndTrainerBattle exactly: cry + battle text, after-battle text without
-  a rematch once EVENT_BEAT_* is set, and the flag/HideObject on any
-  non-blackout result (fleeing loses the legendary, as in Gen 1).
-  Snorlax hides before its battle and only shows the calmed-down/
-  returned line when not caught. Zapdos/Articuno/Moltres/Mewtwo's
-  battle text is a text_far string ending in a bare "...@" terminator
-  (no <DONE>/<PROMPT>) followed by text_asm PlayCry + WaitForSoundToFinish:
-  the box types with no ▼ prompt and auto-closes only once the cry
-  finishes, never on a button press,  ported via `Commands.play_cry`
-  stashing the pending cry for the following `Commands.show_text` to
-  consume as the TextBox's auto-close sound. Voltorb/Electrode's battle
-  text has no PlayCry call in the ROM at all and keeps the ordinary
-  button-wait close.
- Gym leader repeat dialogue (data/scripts/gyms.lua): each leader's
-  text_asm branches on EVENT_BEAT_<LEADER>,  pre-badge talk prints the
-  pre-battle text and engages the leader battle (badge/TM via
-  data/scripts/victories.lua); post-badge talk prints the leader's
-  post-battle advice text (Misty's is her TM11 explanation). The
-  originals' middle branch (beaten but TM not handed over,
-  CheckEventReuseA EVENT_GOT_TM*) is ported too: the victory's GiveItem
-  goes through the bag's capacity check, a full bag shows the leader's
-  "make room" text instead of the received lines and leaves
-  EVENT_GOT_TM* unset, and talking to the leader re-runs the ReceiveTM
-  script until the TM goes in (#797). Giovanni's
-  farewell (`ViridianGymGiovanniText` .afterBeat) hides him inside a
-  fade-to-black/fade-in Transition matching ViridianGym.asm's
-  GBFadeOutToBlack → HideObject → GBFadeInFromBlack, persisted
-  permanently via TOGGLE_VIRIDIAN_GYM_GIOVANNI in save.objectToggles.
- Cable Club receptionists (TX_SCRIPT_CABLE_CLUB_RECEPTIONIST →
-  CableClubNPC, all 12 Pokémon Centers): welcome, pre-Pokédex "making
-  preparations" brush-off, and the apply/save YES-NO are ported;
-  accepting saves the game and opens the link menu, declining prints
-  "Please come again!".
- Cinnabar fossil deposit follows GiveFossilToCinnabarLab: a menu of
-  carried fossils (FossilsList order), SeesFossilText with a Yes/No
-  confirm, ComeAgainText on either cancel.
- Hall of Fame induction: each party mon's front sprite scrolls in from
-  the left at 4px/frame, matching HoFShowMonOrPlayer's .ScrollPic
-  front-pic phase (engine/movie/hall_of_fame.asm); the back-pic's
-  enlarged/blurred pre-wipe is a VRAM-scroll-register trick not
-  replicated in this sprite-based renderer. The finale
-  (HoFDisplayPlayerStats) shows trainer name, play time, money, POKéDEX
-  seen/owned, and Prof. Oak's rating text (engine/events/
-  pokedex_rating.asm DexRatingsTable) from real save data.
- End credits + post-game reset (engine/movie/credits.asm,
-  scripts/HallOfFame.asm): screen-by-screen CreditsOrder pages (hlcoord
-  9,6 + signed columns), FadeInCredits' 4x5-frame ramp, 90/110/120/140-
-  frame holds, DisplayCreditsMon's 27-frame 8px/frame silhouette wipe,
-  LoadCopyrightTiles' three-row block, THE END at (4,8). While THE END
-  is up the HoF script autosaves (wLastBlackoutMap := PALLET_TOWN; the
-  player is saved in the HALL_OF_FAME room), waits 600 frames, then A/B
-  triggers `jp Init`,  the boot sequence replays into the title screen.
- Victory Road's boulder switches replicate the original's
-  ReplaceTileBlock data: 1F boulder at (17,13) -> block $1D at (4,6);
-  2F boulders at (1,16)/(9,16) -> $15 at (3,4) and $1D at (11,7); 3F
-  boulder at (3,5) -> $1D at (3,5), and the (23,15) hole drops the
-  boulder to 2F (hide/show toggle). Barriers are re-applied from flags
-  on map entry, exactly like the originals' map-load scripts.
- Item balls, static legendary encounters and trainer rewards
-  (badges + gym TMs, the Silph Giovanni flag) are generic systems driven
-  by the extracted object args and a hand-ported reward table
-  (data/scripts/victories.lua).
- In-game trades use the real data/events/trades.asm table (species in,
-  species out, original nickname).
-
-## Safari game (engine/events/hidden_events/safari_game.asm + engine/battle)
-
- ¥500 buys 30 SAFARI BALLs and 502 steps (scripts/SafariZoneGate.asm
-  sets `wSafariSteps = 502`); steps count down on the four outdoor zone
-  maps and hitting 0 (or throwing the last ball) ends the game at the
-  gate.
- Safari battles offer BALL / BAIT / ROCK / RUN; no player Pokémon
-  acts.  The working catch rate starts at the species rate; BAIT halves
-  it and adds 1-5 to the bait factor (zeroing the escape factor); ROCK
-  doubles it (cap 255) and adds 1-5 to the escape factor (zeroing bait)
-  -- ItemUseBait/ItemUseRock in engine/items/item_effects.asm.
- Each turn one factor decays ("is eating!" / "is angry!"); when the
-  escape factor decays to 0 the catch rate resets to the species rate
-  (PrintSafariZoneBattleText, engine/battle/safari_zone.asm).
- Flee check (engine/battle/core.asm): `b = 2 * (speed % 256)`; the mon
-  always flees when speed > 127; while eating `b /= 4`, while angry
-  `b = min(255, 2b)`; it flees when `rand(0,255) < b`.
- The SAFARI BALL rolls the ULTRA_BALL rand range (0-150) in the Gen 1
-  catch formula, against the BAIT/ROCK-modified rate.
-
-## Slot machines (engine/slots/slot_machine.asm)
-
- The three reels are the extracted 18-symbol wheel sequences
-  (data/events/slot_machine_wheels.asm); bet 1 plays the middle row,
-  bet 2 adds top+bottom, bet 3 adds both diagonals.
- Payouts: 7-7-7 = 300, BAR = 100, CHERRY = 8, MOUSE/FISH/BIRD = 15
-  (SlotRewardPointers).
- Per-wheel stop/slip rules ported exactly: wheel 1 spends up to 4 slip
-  charges, slipping past a centred CHERRY (in seven-and-bar mode it
-  always slips all 4 via pokered's `cp HIGH(SLOTS7)` bug); wheel 2 stops
-  as soon as wheels 1+2 line up any potential match (pairs checked b/b,
-  b/m, m/m, t/m, t/t) or, in seven-and-bar mode, on 7/BAR; wheel 3 rolls
-  past forbidden matches free and burns wSlotMachineRerollCounter
-  charges on winnable no-match spins, animated tile-by-tile. Luck flags
-  (SetFlags): seven-and-bar mode is sticky across spins; r==0 arms 60
-  allow-matches charges; a BAR win clears flags; a 300 win zeroes the
-  counter and clears flags with probability 128/256; 8/15 wins burn one
-  charge. Lines are checked in asm order with the first match taken;
-  A-presses are ignored while a prior wheel's slip counter is nonzero.
-  Machine and COIN CASE texts are byte-identical
-  (_GameCorner*Text; AbleToPlaySlotsCheck's no-coins gate included).
- Flow brackets: PromptUserToPlaySlots "A slot machine! Want to play?"
-  (YesNoChoice) and MainSlotMachineLoop's "One more go?" (TwoOptionMenu);
-  the x3/x2/x1 coin menu (CoinMultiplierSlotMachineText) defaults its
-  cursor to x3, bet = 3 - menu item. Static frame: the real
-  SlotMachineMap (gfx/slots/slots.tilemap, 20x12 tile ids < $25) blitted
-  from red_slots_1.png, extracted as field.slotSymbols.tilemap
-  (tools/extract/gfx.py extract_slots). Win flash:
-  SlotMachine_CheckForMatches.flashScreenLoop flips rBGP (shade 3->2) b
-  times at 5 frames each, b = 20/8/4/2 for the 300/100/15/8 rewards
-  (SlotReward{300,100,8,15}Func). Payout drip:
-  SlotMachine_PayCoinsToPlayer credits one coin every 8 frames (4 for a
-  7/BAR), SFX_SLOTS_REWARD per coin, rOBP0 symbol flicker every 5 coins.
-
-## Spinner arrow tiles (scripts/*.asm arrow movement tables)
-
- Viridian Gym and Rocket Hideout B2F/B3F keep per-coordinate RLE
-  movement lists (map_coord_movement); each list executes backwards
-  from its terminator (DecodeArrowMovementRLE), sliding the player and
-  chaining onto further arrows.
-
-## Cries (data/pokemon/cries.asm, audio/engine_1.asm)
-
- Each species = a base cry (one of 38 SFX_CryXX streams) + a frequency
-  modifier added to every note's frequency register
-  (Audio1_ApplyFrequencyModifier) + a tempo modifier
-  (`sfx tempo = $80 + length`, Audio1_SetSfxTempo).  All 151 cries are
-  rendered offline with those modifiers applied and play on battle
-  entry and Pokédex pages.
-
-## Hidden events & facility puzzles
-
- Card key doors (engine/events/card_key.asm): door tiles $18/$24
-  (SILPH_CO_11F: $5e) replaced with block $0e ($03 on 11F).
- Vermilion trash cans
-  (engine/events/hidden_events/vermilion_gym_trash.asm): the first-lock
-  can re-rolls on every Vermilion City map load (VermilionCity_Script's
-  Random & $e, even cans) and after every failed second-can guess; the
-  second lock uses the GymTrashCans table verbatim, including the
-  underflow bug that can place it in can 0 regardless of adjacency; a
-  wrong pick resets EVENT_1ST_LOCK_OPENED and re-rolls immediately; only
-  SuccessText3 prints on completion; the gym door block at (2,2) is
-  $24 closed / $5 open (scripts/VermilionGym.asm). SuccessText1/
-  SuccessText3/FailText play SFX_SWITCH/GO_INSIDE/DENIED from each
-  text's text_asm tail after the text prints (DisplayTextID's
-  WaitForTextScrollButtonPress then holds the box), so the port fires
-  them from an onDone on the TextBox, landing the beep as the box
-  closes rather than as it opens.
- Menu close-keys follow pokered's per-menu wMenuWatchedKeys mask, not
-  a single global rule: the shared Menu base (src/ui/Menu.lua) closes
-  on B only, and START-close is opt-in via opts.startCloses. Only the
-  start menu sets it, matching engine/menus/draw_start_menu.asm's
-  PAD_DOWN|PAD_UP|PAD_START|PAD_B|PAD_A; OptionsMenu also closes on
-  START via its own loop, matching engine/menus/main_menu.asm
-  DisplayOptionMenu's explicit B_PAD_B/B_PAD_START checks. Every other
-  menu (bag/PC item lists PAD_A|PAD_B|PAD_SELECT, party menu /
-  BUY-SELL-QUIT / USE-TOSS submenu / PC menus / Pokedex side menu
-  PAD_A|PAD_B) leaves PAD_START unwatched, so START does not close
-  them. START never replays SFX_PRESS_AB (HandleMenuInput_ beeps only
-  for the PAD_A|PAD_B branch).
- Old man tutorial hollow cursor: the item list is itself scripted in
-  pokered (DisplayListMenuID's old-man branch, home/list_menu.asm:65-91)
- ,  no input is read; the filled '▶' hovers POKé BALL for 80 frames,
-  auto-presses A, then PlaceUnfilledArrowMenuCursor leaves the hollow
-  '▷' on that row until ItemUseBall tears the list down for the throw.
-  Ported via ListMenu's opts.script hook (src/ui/ListMenu.lua) and
-  BattleState:openOldManBag driving the same beats. The MissingNo./
-  wGrassRate side effects of the OLD MAN name swap are not modeled, 
-  see docs/gameboy-hardware-limitations.md.
- Gym statues (gym_statues.asm): plaque with the city/leader from each
-  gym's script; the player joins WINNING TRAINERS with the badge.
- Route 22 gate / Route 23 guards: real trigger rows, badge order
-  (EARTH down to CASCADE) and EVENT_PASSED_*_CHECK skip flags.
- Game Corner poster (scripts/GameCorner.asm): block (8,2) $2a -> $43
-  on EVENT_FOUND_ROCKET_HIDEOUT.
- Seafoam Islands (scripts/SeafoamIslandsB3F/B4F.asm): reversed-RLE
-  current paths, Seafoam4HolesCoords boulder holes setting the
-  EVENT_SEAFOAM*_BOULDER*_DOWN_HOLE pairs, the forced pool exit rows.
- Rock Tunnel darkness: wMapPalOffset = 6 on entry, cleared by Flash
-  (BOULDERBADGE) or leaving (home/overworld.asm).
-
-## Battle extras
-
- GROWL/ROAR (GetMoveSound/IsCryMove, engine/battle/animations.asm
-  ~2196): the move's own MoveSoundTable tempo byte (Growl $c0, Roar
-  $40, both pitch $00) layers onto the cry via `Sound.playMoveCry`'s
-  `Source:setPitch(256/(128+tempoMod))`. Transform (engine/gfx/
-  palettes.asm DeterminePaletteID, bit TRANSFORMED): the swapped-in pic
-  is tinted PAL_GRAYMON via `PaletteFX.monPal(data, species,
-  transformed)`, not the copied species' own palette, in
-  `BattleState:speciesSprite`. Growl (DoGrowlSpecialEffects,
-  animations.asm ~928): AnimPlayer's GROWL frame-block branch keeps a
-  `growlNoteTrail` snapshot so each block's emitted sprites include the
-  previous block's note copy alongside the current one (GROWL skips
-  AnimationCleanOAM between blocks per the `cp GROWL` check ~line 145);
-  ROAR is unaffected since the asm never applies this quirk to it.
- Master/Ultra ball tosses flicker the OBJ palette: DoBallTossSpecial
-  Effects (engine/battle/animations.asm:685) XORs rOBP0 with %00111100
-  after every frame block while wCurItem <= ULTRA_BALL, so the 11 toss
-  blocks alternate the $F0/$CC shade maps starting normal; PlayAnimation
-  pushes/pops rOBP0 around each subanimation row, so the ambient
-  palette returns when the toss ends. GREAT/POKE/SAFARI balls never
-  flicker, and the toss arc always follows wCurItem via
-  TossBallAnimation, including the ghost-dodge throw.
- Anim-layer OBJ colorization is per 8x8 attribute cell: the SGB's
-  ATTR_BLK regions color the composited DMG picture per cell, not per
-  OAM entry, so an anim sprite overlapping a zone boundary takes each
-  cell's palette on the pixels inside it,  AnimPlayer samples the zone
-  under every cell an 8x8 tile touches and repaints differing cells
-  through a cell-clipped scissor (aligned tiles stay one draw).
- Ball wobbles (ItemUseBall): Z = X*Y/255 + status2 with
-  Y = rate*100/ballFactor2; <10/<30/<70 -> 0/1/2 shakes, else 3, with
-  the matching ItemUseBallText01-04 lines.
- Trainer class AI (data/trainers/ai_pointers.asm +
-  engine/battle/trainer_ai.asm): per-class item/switch routines with
-  wAICount uses per Pokémon, ported to data/scripts/ai_classes.lua.
- Exp (engine/battle/experience.asm): baseExp*level/7 divided by the
-  participant count, x1.5 for trainers, x1.5 for traded mons; stat exp
-  in full to each participant.
- Move sounds: data/moves/sfx.asm (sound + pitch/tempo per move). The
-  pitch/tempo modifiers are applied at synthesis time
-  (Audio2_ApplyFrequencyModifier adds pitch to every frequency write;
-  Audio2_SetSfxTempo scales tone-channel note lengths, noise skips it), 
-  128 variant WAVs keyed "<sfx>@<pitch><tempo>" that Sound.playMove
-  selects, exact rather than a playback-rate approximation. Per-row
-  sounds fire as PlayAnimation does; GROWL/ROAR (IsCryMove) play the
-  attacker's cry. Hit sounds by effectiveness (Damage/Super/NotVery).
- Screen-effect animations (engine/battle/animations.asm +
-  engine/gfx/screen_effects.asm): every SE_* is implemented per-routine, 
-  FlashScreen/FlashScreenLong (the FlashScreenLongSGB 12-entry table),
-  Dark/Light/DarkenMon/Reset palette ops (shade-map permutations of the
-  SGB zone palettes), all SlideMon variants, ShakeBackAndForth,
-  BoundUpAndDown, SquishMonPic, Minimize (real MinimizedMonSprite),
-  spiral/shoot-balls/water-droplets/leaves emitters compiled from the
-  asm trajectories, per-animation-id frame-block flashes (Explosion,
-  Rock Slide's rumbles, Blizzard's cadence...), AnimationWavyScreen with
-  true per-scanline offsets, PredefShakeScreenHorizontally/Vertically
-  and ShakeEnemyHUD. SE rows carry the faithful blocking durations.
- SGB battle colorization (SetPal_Battle, BlkPacket_Battle,
-  SetAnimationPalette): the battle screen is colorized by zone,  player
-  HUD, enemy HUD, player mon + message box, enemy mon; trainer front
-  pics and the player/old-man back pics take PAL_MEWMON (both species
-  IDs are zero at the intro, so MonsterPalettes[0]); the ghost keeps the
-  disguised species' palette; attack animation sprites and thrown balls
-  are colored through the OBJ palettes (wAnimPalette $F0 on SGB, ambient
-  $E4, OBP1 $6C). Headless/no-shader environments fall back to the flat
-  pipeline.
- Mimic resolves mid-move (MimicEffect): accuracy first, then the
-  player's copy menu (enemy/link copy a random slot); the copy
-  overwrites only the slot's move ID,  PP is shared with Mimic's slot, 
-  and reverts on switch/battle end.
- Old man tutorial (DisplayBattleMenu's BATTLE_TYPE_OLD_MAN branch): the
-  real scripted cursor,  ▶ beside FIGHT for 80 frames, beside ITEM for
-  50, ITEM force-selected into the POKé BALL x50 list; the throw always
-  catches at full HP (item_effects.asm jumps straight to .captured, 3
-  shakes, no party/dex add, no ball consumed); backing out of the bag
-  replays the script. The old man never attacks,  the original tutorial
-  is menu navigation + a guaranteed catch, nothing more.
-
-## Link battles (lockstep)
-
- Both sides simulate with a shared Park-Miller RNG stream (host deals
-  the seed), identical pack/unpack-clamped party copies, no badge
-  boosts, and a mirrored speed-tie roll (the guest inverts it); a
-  canonical host-side-first state hash is exchanged per turn and any
-  mismatch ends the match as a draw.
-
-## Music (audio/engine_1.asm)
-
- Note duration: `frames = length * speed * tempo / 0x100` with
-  fractional carry, at 60 fps (Audio1_note_length / CalculateDelay).
- Frequency: `reg = pitches[note] asr (octave - 1)` (CalculateFrequency;
-  the octave byte stores `8 - octave`), `f = 131072/(2048 - reg)` for
-  squares, halved for channel 3.
- note_type volume/fade renders as an NRx2-style envelope (step every
-  `fade/64` s); duty_cycle maps to 12.5/25/50/75% pulse widths;
-  sound_call/sound_loop honor the engine's one-level call stack and
-  loop counters.
-
-## Text & font
-
- The Pokédex height row uses the real ′/″ tiles: gfx/pokedex/pokedex.png
-  tiles 0/1 are patched over font-extra slots $60/$61 exactly as
-  engine/gfx/load_pokedex_tiles.asm loads them over vChars2 (they replace
-  glyphs charmap.asm marks unused); ASCII `"` aliases to the closing-
-  quote glyph $73 so stray hand-written quotes render.

-# Pokémon Gold, Silver, and Crystal: A Systematic Engine, ASM, and Behavioral Comparison
-
-## Executive summary
-
-Pokémon Gold and Silver are best understood as **two data-configured builds of one engine**, whereas Pokémon Crystal is an **expanded, reorganized, Color-only derivative of that engine**. The `pret/pokegold` repository reproducibly builds the international Gold and Silver ROMs byte-for-byte, while `pret/pokecrystal` separately builds multiple international Crystal revisions and debug artifacts. This makes the two repositories unusually strong primary evidence: their output hashes correspond to known retail binaries rather than merely reimplementing observed behavior.
-
-The largest technical conclusion is that Crystal is **not a ground-up engine rewrite**. Core subsystems (the frame-driven sound interpreter, hardware-derived RNG, synchronized link-battle PRNG, wild-encounter probability machinery, party-mon record size, and much of the RTC pipeline) remain recognizably inherited from Gold/Silver. Crystal instead adds new ROM banks, reorganizes routines, introduces Color-specific rendering paths, fills formerly reserved fields in Pokémon records, redesigns SRAM placement, and layers Battle Tower, Mobile System GB, animated sprites, the female protagonist, Buena, Move Tutor, Suicune story logic, and Virtual Console hooks around the inherited core.
-
-The most important behavioral differences are therefore caused less by wholesale algorithm replacement than by **changed control flow and data**:
-
-| Area | Gold and Silver | Crystal | Technical consequence |
-|---|---|---|---|
-| Edition structure | One shared engine with edition-selected encounter, sprite, title, and other data | One enhanced-version build with regional/revision conditionals | Gold-to-Silver ports are mostly data substitutions; Gold/Silver-to-Crystal ports are architectural merges |
-| Display target | Runtime distinguishes DMG/SGB/CGB modes | Explicit Color-only path | Crystal code can assume CGB palettes, VRAM banking, and related presentation behavior more aggressively |
-| RNG core | Divider-register accumulator plus synchronized link PRNG | Same algorithms | Different outcomes normally arise from different call timing or paths, not a different generator |
-| Party records | Two bytes after Pokérus are reserved | Those same bytes become caught-time/gender/level/location metadata | Pokémon records remain structurally compatible despite Crystal gaining metadata |
-| Save layout | Main and backup data are fragmented among SRAM sections | Main and backup records become more contiguous; Crystal/Battle Tower/Mobile blocks are added | Whole `.sav` files are not drop-in interchangeable |
-| Battles | Standard Gen II battle engine | Inherited engine plus Battle Tower branches and selective bug fixes | Link-compatible behavior is intentionally retained in some otherwise-fixed cases |
-| Roaming Pokémon | Raikou, Entei, and Suicune use the roaming system | Only Raikou and Entei roam; Suicune becomes a scripted encounter | Encounter-state conversion requires special handling |
-| Graphics | Static Pokémon fronts and DMG/SGB-compatible layouts | Animated fronts, revised sprites, richer Color layouts | Animation introduces new graphics data, decompression, frame, and timing requirements |
-| Audio | Shared four-channel Game Boy music interpreter | Same interpreter plus new songs and call sites | Music ports are mostly data/pointer work rather than synthesizer rewrites |
-| Major fixed defects | Coin Case arbitrary code execution, first-save Hall of Fame corruption, Lucky Number box limit, and several map/text defects | Corrected | Crystal is safer, but not "bug-fixed Gen II" in the broad sense |
-| Persistent defects | Many Gen II battle, capture, item, and badge defects | Many remain | Mechanical compatibility often outweighed cleanup |
-
-Gold and Silver themselves have almost no meaningful engine-level divergence. Their scientifically interesting comparison is principally **which tables and assets are selected at assembly time**. Crystal is the meaningful engine comparison.
-
-The report assumes a technically literate audience familiar with low-level programming but not necessarily Game Boy internals. Unless explicitly stated, "Crystal" means the international English code represented by `pret/pokecrystal`; Japanese Mobile System GB and Australian/revision-specific behavior are treated as regional variants. "Scientific" here means reproducible binary-derived comparison, explicit source hierarchy, and separation of direct evidence from inference, not laboratory experimentation involving original development source code, which has not been publicly released.
-
-## Scope, evidence, and reproducibility
-
-### Source hierarchy
-
-The strongest sources are the two pret disassemblies:
-
- [`pret/pokegold`](https://github.com/pret/pokegold), which builds exact Gold and Silver international ROM images.
- [`pret/pokecrystal`](https://github.com/pret/pokecrystal), which builds Crystal international v1.0, v1.1, Australian, and debug images.
-
-The repositories identify exact SHA-1 outputs. Gold builds to `d8b8a3600a465308c9953dfa04f0081c05bdcb94`, Silver to `49b163f7e57702bc939d642a18f591de55d92dae`, Crystal international v1.0 to `f4cd194bdee0d04ca4eac29e09b8e4e9d818c133`, and Crystal international v1.1 to `f2f52230b536214ef7c9924f483392993e226cfb`. Those reproducible identities are critical: a label such as `BadgeStatBoosts` is a reverse-engineered name, but the emitted bytes and resulting behavior are those of the retail ROM.
-
-Secondary sources such as Bulbapedia and Serebii are useful for player-visible cross-checking, release differences, encounter availability, and historical context. The pret bug documents are stronger than ordinary wiki summaries for defects because they identify the responsible instructions and provide corrective diffs. Official Nintendo and Pokémon sources are most valuable for release/Virtual Console behavior and supported transfer paths, but they do not publish the games' assembly architecture.
-
-### Reproducible comparison method
-
-A rigorous comparison should operate at four levels:
-
-| Level | Method | What it establishes | Main limitation |
-|---|---|---|---|
-| Binary identity | Build each repository with its pinned RGBDS-compatible toolchain and verify SHA-1 | The source corresponds to the target retail ROM | Does not explain why bytes differ |
-| Source topology | Compare `main.asm`, `home.asm`, bank sections, include graphs, WRAM/SRAM declarations | Architectural additions, removals, and relocation | File organization can change without behavioral change |
-| Routine semantics | Compare labels, branches, register use, calls, data offsets, and side effects | Control-flow and algorithmic differences | Labels and comments are community-derived |
-| Behavioral validation | Run controlled emulator tests with trace logging and fixed input timing | Observable consequences and RNG/cycle sensitivity | Emulator accuracy and RTC state must be controlled |
-
-For a formal experiment, the recommended independent variables are edition, ROM revision, initial SRAM, RTC register state, boot hardware mode, input sequence, and link mode. Dependent variables include RNG bytes, encounter choice, battle result, SRAM writes, audio commands, VRAM/OAM writes, and cycle/frame number. Because the ordinary RNG reads the divider register, deterministic comparisons must start from a controlled boot state and reproduce input timing at frame or cycle precision.
-
-### Gold versus Silver as a build-configuration comparison
-
-The fact that `pokegold` emits both Gold and Silver from one repository is itself strong evidence that the two versions share the same broad code architecture. Edition differences are implemented through conditional assembly and alternate data or assets rather than through separate engines. The obvious behavioral results are version-specific wild Pokémon, title graphics, mascot-facing presentation, and selected NPC or table data; battle arithmetic, saves, RTC processing, audio interpretation, and link handling come from the same shared source.
-
-This distinction matters for analysis. Treating Gold, Silver, and Crystal as three equally separate engines exaggerates Gold/Silver differences and understates Crystal's structural changes. A better model is:
-

-flowchart TD

-
-## ROM and engine architecture
-
-### Banked execution model
-
-The games execute on the Game Boy's LR35902-class CPU and are organized around a fixed home bank plus switchable ROM banks. Calls across banks generally pass through wrappers that save the current bank, select the target bank, call the routine, and restore the original bank. The `BattleRandom` wrapper is a concise example: `_BattleRandom` resides outside the home bank, so the wrapper saves `hROMBank`, uses the bank-switch restart vector, calls the routine, preserves its return value, and restores the previous bank.
-
-```asm
-BattleRandom::
-    ldh a, [hROMBank]
-    push af
-    ld a, BANK(_BattleRandom)
-    rst Bankswitch
-    call _BattleRandom
-    ...
-    pop af
-    rst Bankswitch
-    ret
-```
-
-Relevant sources: [Gold/Silver `home/random.asm`](https://github.com/pret/pokegold/blob/a0dad0957ac8a9ffa67e950ee3ab6715a212ded5/home/random.asm#L29-L46) and [Crystal `home/random.asm`](https://github.com/pret/pokecrystal/blob/8e8f7e20052a596371a77022f0392c285e51bbf1/home/random.asm#L29-L46).
-
-The repositories' top-level `main.asm` files are effectively link manifests for this architecture. Gold/Silver's file groups the battle core, encounters, party menu, RTC, phone, Pokégear, sprite animation, graphics loading, and other systems into named ROM sections. Crystal retains those categories but adds explicitly named feature sections and many additional modules.
-
-### Crystal as an extension and bank-layout rewrite
-
-Crystal's `main.asm` introduces a conspicuous `Crystal Features 1` section containing gender initialization, Kris-specific bag handling, Move Tutor, Crystal layouts, Celebi logic, the redesigned main menu, Mobile menu code, owned-Pokémon search, and Buena's menu. Nearby banks add Battle Tower trainer logic, caught-data handling, a revised stats screen, sliding battle intros, battle-scene checks, and the Color-only startup screen.
-
-That include topology supports three conclusions.
-
-First, Crystal preserves **vertical subsystem continuity**. The battle engine is still `engine/battle/core.asm`; encounters remain `engine/overworld/wildmons.asm`; Pokémon records still derive from the same party/box macros; and audio is still driven by the same interpreter.
-
-Second, Crystal adds **horizontal feature coupling**. Battle Tower touches battle setup, stat boosts, experience rules, saving, menus, SRAM, trainers, music, and link-like constraints. The female protagonist touches initialization, sprites, bag graphics, caught metadata, and menu presentation. Mobile support touches interrupts, SRAM, menus, communications, rankings, and audio.
-
-Third, code and data relocation is substantial enough that raw ROM addresses from Gold/Silver cannot generally be transplanted into Crystal. A symbolic port based on labels and structures is practical; a patch based on absolute offsets is brittle.

-
-The line counts of several Crystal files are larger, but line count alone is not a behavioral metric; comments, label quality, and source refactoring affect it. The stronger evidence is the presence of new branches, fields, tables, and externally observable side effects.
-
-### Hardware-mode divergence
-
-Gold/Silver initialization tests whether the console is a Game Boy Color and maintains non-CGB paths, including Super Game Boy initialization. Crystal includes an explicit `gbc_only.asm` module that displays the incompatibility message on non-CGB hardware. That is not merely marketing metadata: it changes what assumptions later rendering code may safely make about palettes, VRAM banking, and Color hardware.
-
-For a reverse port of Crystal features into Gold/Silver, every CGB-only feature falls into one of three categories: provide a monochrome/SGB fallback, disable it outside CGB mode, or intentionally convert the resulting ROM into a Color-only build. Skipping that decision produces subtle failures rather than one clean compile error: palette attributes, second-bank VRAM data, and tile-upload timing can all be implicated.
-
-## Save, RNG, clock, and entity state
-
-### Save architecture
-
-Gold/Silver divide their main game state into options, three player-data fragments, current-map data, Pokémon data, and a checksum. Backup pieces are distributed among several separately placed SRAM sections. The current PC box is separate, the fourteen inactive boxes occupy exactly two SRAM banks, and mail and Mystery Gift have dedicated regions.
-
-Crystal instead defines a contiguous `sGameData` consisting of player, map, and Pokémon data, pads the region, and stores a checksum. Its backup is similarly grouped. Crystal then adds a GS Ball flag, `sCrystalData`, Battle Tower progress and recent-trainer state, ranking records, Mobile communication data, offers, credentials, and Japanese Mobile-specific buffers. The source explicitly notes that the international `sCrystalData` location differs from Japanese Crystal.
-
-| Save component | Gold/Silver | Crystal |
-|---|---|---|
-| Options and corruption sentinels | Present | Present |
-| Main player/map/Pokémon data | Split into labeled player fragments inside the save region | Grouped into one contiguous main-game block |
-| Main checksum | 16-bit checksum after game data | 16-bit checksum after padded game-data region |
-| Backup | Fragmented among multiple SRAM sections | Consolidated backup game-data block |
-| Current box | Separate `curbox` structure | Separate full `box` structure plus padding |
-| Inactive boxes | Fourteen boxes over two SRAM banks | Same fourteen-box capacity over two banks |
-| Party and mailbox mail | Dedicated primary and backup regions | Same broad model |
-| GS Ball state | Absent | Primary and backup flags |
-| Battle Tower | Absent | Challenge state, streak, previous teams, reward |
-| Mobile/rankings | Absent | Several additional SRAM sections |
-| Full-file compatibility | Gold and Silver are closely related but still edition-specific | Not layout-compatible with Gold/Silver |
-
-Crystal's save routine makes the transactional sequence visible:
-
-```asm
-_SaveGameData:
-    farcall StageRTCTimeForSave
-    farcall BackupMysteryGift
-    call ValidateSave
-    call SaveOptions
-    call SavePlayerData
-    call SavePokemonData
-    call SaveBox
-    call SaveChecksum
-    call ValidateBackupSave
-    ...
-    farcall BackupGSBallFlag
-    farcall SaveRTC
-```
-
-Source: [Crystal `engine/menus/save.asm`](https://github.com/pret/pokecrystal/blob/8e8f7e20052a596371a77022f0392c285e51bbf1/engine/menus/save.asm#L255-L284). The routine stages RTC state, writes the primary data and box, computes the primary checksum, writes backup data and checksum, backs up party mail and GS Ball state, persists RTC state, and normalizes a completed Battle Tower reward state.
-
-The practical conclusion is precise: **do not migrate a Gold/Silver `.sav` to Crystal by copying the file or the main save block**. A converter should parse symbolic fields, validate checksums and sentinels, copy player/map/Pokémon/box/mail data field by field, initialize Crystal-only state, and regenerate Crystal checksums. Gold-to-Silver conversion is less structurally disruptive, but version-dependent event and encounter state should still be treated deliberately.
-
-### Party and boxed-Pokémon records
-
-One of Crystal's most elegant compatibility decisions is visible at the structure-definition level. In Gold/Silver, the two bytes after `MON_POKERUS` are simply reserved:
-
-```asm
-DEF MON_HAPPINESS rb
-DEF MON_POKERUS   rb
-                  rb_skip 2
-DEF MON_LEVEL     rb
-```
-
-In Crystal, the same positions are assigned to a two-byte caught-data field:
-
-```asm
-DEF MON_HAPPINESS  rb
-DEF MON_POKERUS    rb
-DEF MON_CAUGHTDATA rw
-DEF MON_LEVEL      rb
-```
-
-Sources: [Gold/Silver structure](https://github.com/pret/pokegold/blob/a0dad0957ac8a9ffa67e950ee3ab6715a212ded5/constants/pokemon_data_constants.asm#L83-L101) and [Crystal structure](https://github.com/pret/pokecrystal/blob/8e8f7e20052a596371a77022f0392c285e51bbf1/constants/pokemon_data_constants.asm#L83-L107).
-
-Crystal packs caught time and trainer gender into one byte and caught level and location into another. Because Game Freak repurposed reserved bytes instead of extending the record, `BOXMON_STRUCT_LENGTH` and `PARTYMON_STRUCT_LENGTH` remain compatible. Gold/Silver can carry those bytes without understanding them; Crystal can interpret them when present. This is a major reason Gen II Pokémon can move among Gold, Silver, and Crystal without a record-size translation layer.
-
-A second structure change appears in the base-species TM/HM compatibility bitset. Gold/Silver size it for `NUM_TM_HM`; Crystal sizes it for `NUM_TM_HM_TUTOR`, accommodating Move Tutor compatibility in the same species-data model. This means a straight copy of Gold/Silver base-stat records into Crystal must account for Crystal's expanded learnability domain even if the visible species stats are unchanged.
-
-### Item and party handling
-
-The basic inventory model (separate item pockets, held-item byte in each Pokémon record, party length of six, PC boxes, mail records, and item-dispatch routines) is inherited. Crystal's changes are concentrated in new consumers and UI behavior: Move Tutor eligibility, gender-specific player presentation, caught metadata, Battle Tower restrictions, and additional event items such as GS Ball state.
-
-Crystal did **not** comprehensively repair the item mechanics. Its documented defects still include Moon Ball not applying its intended multiplier, Love Ball checking the wrong gender relationship, Fast Ball applying to only a few species, three incorrect Heavy Ball weight cases, and status conditions failing to affect capture rate as intended. Those defects live in shared mechanical paths and are important when evaluating a "faithful" engine port: correcting them changes gameplay and may alter deterministic test vectors.
-
-### Ordinary RNG
-
-Gold/Silver and Crystal use the same ordinary RNG routine. It samples the hardware divider register and updates two one-byte accumulators, one by addition-with-carry and one by subtraction-with-carry:
-
-```asm
-ldh a, [rDIV]
-ld b, a
-ldh a, [hRandomAdd]
-adc b
-ldh [hRandomAdd], a
-
-ldh a, [rDIV]
-ld b, a
-ldh a, [hRandomSub]
-sbc b
-ldh [hRandomSub], a
-```
-
-Sources: [Gold/Silver](https://github.com/pret/pokegold/blob/a0dad0957ac8a9ffa67e950ee3ab6715a212ded5/home/random.asm#L13-L27) and [Crystal](https://github.com/pret/pokecrystal/blob/8e8f7e20052a596371a77022f0392c285e51bbf1/home/random.asm#L13-L27). The files are effectively identical, including the `RandomRange` rejection-sampling routine used to avoid simple modulo bias.
-
-This generator is not a self-contained seeded PRNG in the modern sense. Its output depends on divider phase, previous accumulator state, carry state, VBlank updates, and when the routine is reached. Consequently, adding an animation, menu delay, conditional call, or extra random-consuming feature can alter later outcomes even while the RNG instructions remain unchanged.
-
-### Link-battle PRNG
-
-Battles route randomness through `BattleRandom`. In non-link play, `_BattleRandom` ultimately uses the ordinary RNG. In linked battles, both systems consume a shared ten-byte random sequence and advance bytes with the recurrence:
-
-```
-x[n+1] = (5 * x[n] + 1) mod 256
-```
-
-The Gold/Silver and Crystal battle cores contain the same broad synchronization mechanism.
-
-This has a major compatibility consequence: a battle patch can be logically correct in isolation yet break link play if it causes one participant to make a different number or order of RNG calls. That is why Crystal sometimes preserves Gold/Silver behavior specifically in link battles. Synchronization depends on matching control flow, not merely using the same random-number formula.
-
-### RTC and time-of-day behavior
-
-Both codebases latch the MBC3-style real-time clock, read seconds, minutes, hours, and the low/high day registers, normalize time, add the player's selected starting offset, and derive the current time-of-day state. Crystal's `UpdateTime` remains a short chain of `GetClock`, `FixDays`, `FixTime`, and `GetTimeOfDay`.
-
-Crystal's source shows the day counter reduced modulo 140 for the game's weekly/event model, with status flags distinguishing an RTC count beyond 139 days and a hardware day-high overflow beyond 255 days. The displayed game time is formed by adding the new-game start offsets to RTC values with carry through seconds, minutes, hours, and day.
-
-The notable architectural addition is the Crystal timer interrupt's Mobile dispatch:
-
-```asm
-Timer::
-    push af
-    ldh a, [hMobile]
-    and a
-    jr z, .not_mobile
-    call MobileTimer
-.not_mobile
-    pop af
-    reti
-```
-
-Source: [Crystal `home/time.asm`](https://github.com/pret/pokecrystal/blob/8e8f7e20052a596371a77022f0392c285e51bbf1/home/time.asm#L2-L11). The ordinary RTC logic remains inherited; Japanese/mobile Crystal adds another timing consumer.
-
-For emulators, flash cartridges, and ports, SRAM alone is insufficient. RTC registers, halt/carry state, elapsed host time, and game offsets must be preserved consistently. A save imported without corresponding RTC state may be structurally valid yet produce incorrect daily events, phone behavior, berries, swarms, day-of-week encounters, or time-dependent evolutions.
-
-## Battles and encounters
-
-### Battle-engine inheritance
-
-The core Gen II battle model is shared: turn selection, speed ordering, accuracy, damage, stat stages, held items, status, volatile effects, experience, capture, AI, and link synchronization follow the same broad engine. Crystal's battle core is larger principally because it adds Battle Tower integration, additional presentation paths, and selective corrections.
-
-Crystal is therefore mechanically closer to a patched and extended Gold/Silver than to a later-generation ruleset. There are no abilities, natures, modern physical/special move split, or rewritten damage model. Its new content operates within Gen II's existing move and Pokémon structures.
-
-### Control-flow difference: Battle Tower exclusions
-
-Gold/Silver's `BadgeStatBoosts` exits for link battles and otherwise applies badge boosts. Crystal adds a second early return when `wInBattleTowerBattle` is nonzero:
-
-```asm
-ld a, [wLinkMode]
-and a
-ret nz
-
-ld a, [wInBattleTowerBattle]
-and a
-ret nz
-```
-
-Source: [Crystal `BadgeStatBoosts`](https://github.com/pret/pokecrystal/blob/8e8f7e20052a596371a77022f0392c285e51bbf1/engine/battle/core.asm#L6526-L6532). Gold/Silver have only the link-mode guard at the corresponding point.
-
-This tiny six-instruction addition is representative of Crystal's design. The stat algorithm was not replaced; Crystal introduced a new battle context and inserted a guard so adventure-only badge advantages do not leak into the standardized Battle Tower. Similar context checks appear around experience and other post-battle handling.
-
-### Selective fixes constrained by link compatibility
-
-The pret Crystal bug documentation explicitly states that Crystal fixed Gold/Silver's Reflect/Light Screen overflow and Present damage behavior only where doing so would not break ordinary cross-version link battles. Link-mode behavior retains the compatible path.
-
-That is an important historical engineering tradeoff. A fully corrected Crystal battle engine would disagree with Gold/Silver on intermediate values and potentially on RNG consumption, damage, fainting, or message sequence. Compatibility with the installed base was treated as a protocol requirement. Consequently, "Crystal fixed the bug" can mean **fixed in single-player but deliberately retained in linked simulation**.
-
-### Shared and persistent battle defects
-
-Crystal retains a substantial Gen II defect surface. Documented examples include:
-
-| Defect | Mechanical effect | Crystal status |
-|---|---|---|
-| "100%" secondary effects | Fail in 1/256 qualifying cases | Retained |
-| Belly Drum | May maximize Attack even when the HP requirement is not properly met | Retained |
-| Berserk Gene | Confusion duration can become 256 turns or inherit stale state | Retained |
-| Confusion damage | Can receive type-item and Explosion/Self-Destruct modifiers | Retained |
-| Beat Up | Can behave incorrectly and can desynchronize link battles | Retained |
-| Return/Frustration edge | Can produce zero damage at extreme happiness values | Retained |
-| Dragon boosting item | Dragon Scale is checked instead of Dragon Fang | Retained |
-| Glacier Badge | Special Defense boost depends incorrectly on overwritten accumulator state | Retained |
-| Capture status bonus | Burn, poison, and paralysis do not contribute as intended | Retained |
-| Specialty Balls | Multiple Apricorn-ball formulas target the wrong condition or table | Retained |
-
-These are documented against original Crystal code, not inferred from modern competitive summaries.
-
-The Glacier Badge defect is especially instructive at ASM level. The routine shifts a badge bitfield through register `b`, calls `BoostStat`, and later reuses register `a` as if it still contained the expected badge value. `BoostStat` can overwrite `a`, so whether Special Defense receives its boost depends on the Special Attack calculation's resulting register state. The bug survived Crystal even though the source gained an explicit comment identifying it.
-
-### Gold/Silver defects corrected in Crystal
-
-The `pokegold` bug document separates defects fixed in Crystal from defects still shared with it. It identifies seven clear Gold/Silver corrections: Coin Case arbitrary code execution, Hall of Fame corruption when no prior save exists, Lucky Number failure to inspect boxes 10-14, Present text overflow, surfing onto NPCs, fishing inside Cerulean Gym, and Route 15 capitalization.
-
-The Coin Case correction is one bytecode-level terminator change:
-
-```diff
- text "Coins:"
- line "@"
- text_decimal wCoins, 2, 4
-done
-+text_end
-```
-
-Source: [`pokegold/docs/bugs_and_glitches.md`](https://github.com/pret/pokegold/blob/a0dad0957ac8a9ffa67e950ee3ab6715a212ded5/docs/bugs_and_glitches.md#L20-L34). The Gold/Silver terminator permits text-command execution to continue into unintended memory under exploitable conditions; Crystal ends the text stream correctly.
-
-The Hall of Fame correction adds a saved-at-least-once check and erases/initializes previous-save structures before attempting the Hall of Fame write. The Lucky Number correction changes the loop bound from the Japanese box count constant to the international fourteen-box count. Both are good examples of Crystal correcting localization-sensitive state assumptions rather than changing game design.
-
-### Encounter-rate algorithm
-
-Gold/Silver and Crystal use essentially the same high-level encounter pipeline:
-
-```mermaid
-flowchart TD
-    STEP[Eligible movement step]
-    RATE[Read morning/day/night or water rate]
-    MOD1[Apply radio modifier]
-    MOD2[Apply Cleanse Tag modifier]
-    ROLL[Call Random and compare with rate]
-    SLOT[Choose encounter slot]
-    ROAM[Check roaming Pokémon]
-    REPEL[Apply Repel level check]
-    BATTLE[Stage wild battle]
-
-    STEP --> RATE --> MOD1 --> MOD2 --> ROLL
-    ROLL -->|pass| SLOT
-    SLOT --> ROAM
-    ROAM --> REPEL
-    REPEL --> BATTLE
-```
-
-In both engines, `TryWildEncounter` gets the map rate, applies Pokémon March/Ruins of Alph doubling or Pokémon Lullaby halving, applies Cleanse Tag halving, draws an RNG byte, chooses a slot from grass or water probability tables, and checks Repel.
-
-Grass records contain separate morning, day, and night slot blocks; the active block is selected through `wTimeOfDay`. Water uses a separate rate and three-slot table. The structure constants remain seven grass slots and three water slots in both codebases.
-
-### Encounter-table differences
-
-Gold and Silver primarily diverge through edition-conditioned tables. Crystal has its own consolidated tables and changes both availability and placement. It makes several former Gold/Silver exclusives obtainable in one edition, while removing some species available in both base versions; Mareep's evolutionary family is a prominent Crystal omission. Crystal also moves species such as Sneasel to different locations.
-
-The engine/table distinction is important. An encounter may differ because:
-
-1. the map's encounter-rate byte changed;
-2. a morning/day/night slot changed;
-3. the slot's level changed;
-4. a swarm override changed;
-5. a roaming Pokémon was removed from the roaming subsystem;
-6. the map itself gained or lost encounter-enabled tiles.
-
-A robust diff should therefore compare map headers, wild tables, swarm flags, and roaming initialization, not merely produce a Pokédex availability list.
-
-### Swarms and roaming state
-
-Gold/Silver's swarm lookup is comparatively generic: it compares the current map against `wSwarmMapGroup` and `wSwarmMapNumber`. Crystal's code has explicit Dunsparce and Yanma swarm flags and corresponding map state. That is a data-model specialization, not just a changed encounter table.
-
-The roaming difference is even clearer. Gold/Silver initialize three records:
-
-```asm
-ld a, RAIKOU
-ld [wRoamMon1Species], a
-ld a, ENTEI
-ld [wRoamMon2Species], a
-ld a, SUICUNE
-ld [wRoamMon3Species], a
-```
-
-Crystal initializes only Raikou and Entei:
-
-```asm
-ld a, RAIKOU
-ld [wRoamMon1Species], a
-ld a, ENTEI
-ld [wRoamMon2Species], a
-```
-
-Sources: [Gold/Silver `InitRoamMons`](https://github.com/pret/pokegold/blob/a0dad0957ac8a9ffa67e950ee3ab6715a212ded5/engine/overworld/wildmons.asm#L471-L511) and [Crystal `InitRoamMons`](https://github.com/pret/pokecrystal/blob/8e8f7e20052a596371a77022f0392c285e51bbf1/engine/overworld/wildmons.asm#L476-L506).
-
-Gold/Silver's subsequent selection logic describes an equal choice among three beasts after the roaming check succeeds; Crystal changes the corresponding comment and index range to two. Suicune's removal is tied to Crystal's expanded Eusine/Suicune plot and scripted Tin Tower encounter.
-
-For save conversion, a Gold/Silver Suicune roaming record cannot simply remain active in Crystal. The converter must map capture/defeat/event state into Crystal's scripted Suicune flags or deliberately define a hybrid behavior.
-
-## Graphics and audio
-
-### Tile, palette, and sprite model
-
-All three games retain the Game Boy's tile-oriented rendering model: graphics are stored as compact tile data, decompressed or copied into VRAM, arranged through background/window tilemaps, and supplemented by hardware sprites through shadow OAM. Pokémon and many UI images use four-color source palettes, with separate palette data determining their actual colors. The pokecrystal FAQ explicitly notes the four-color paletted-PNG convention and the distinction between image data and palette data.
-
-Gold/Silver must support original Game Boy-style output and Super Game Boy behavior as well as Game Boy Color enhancements. Crystal's explicit Color-only startup path lets it make stronger use of CGB layout and palette machinery. Its top-level architecture adds `crystal_layouts.asm`, dedicated player graphics, revised map and battle presentation, and other CGB-focused modules.
-
-### Animated Pokémon sprites
-
-Crystal's headline renderer change is animated front sprites. Every Pokémon receives an entrance animation, and the status/profile viewer can play a longer animation; several designs, palettes, and back sprites were also revised. Crystal additionally gives the legendary beasts distinct overworld sprites and introduces richer trade-screen presentation.
-
-At the engine level, this requires more than storing extra frames. A full animation path needs:
-
- a base front picture and additional frame or bitmask data;
- frame sequencing and duration state;
- tile-buffer reconstruction or differential tile updates;
- synchronization with battle intro control flow;
- palette and VRAM updates during safe LCD periods;
- fallback behavior for static contexts such as link displays or icons.
-
-Crystal's `load_pics.asm` is correspondingly larger and is integrated with dedicated animation and battle-intro modules, while Gold/Silver's loader primarily services static front/back pictures. The exact file-size difference should not be treated as a performance measurement, but the added code paths confirm a broader graphics pipeline.
-
-Animated fronts can also alter RNG-observable timing indirectly. The ordinary RNG is updated from divider timing and VBlank activity; therefore, any test that compares post-animation random outcomes must control whether animations are enabled and how many frames elapsed. This is an inference from the animation and RNG architectures, not evidence that every animation directly invokes `Random`.
-
-### Color and protagonist handling
-
-Crystal adds player-gender initialization and Kris-specific bag/player graphics. The Pokémon record's caught-data bits can record whether the catcher was the boy or girl protagonist. This is an example of a feature spanning UI, overworld sprites, menus, Pokémon metadata, and save state rather than existing in one isolated "female player" switch.
-
-A Crystal-to-Gold/Silver backport must decide how to handle caught-by-girl metadata when Gold/Silver have no female protagonist UI. Structurally the bytes can survive because they were reserved, but Gold/Silver will not natively display or generate the metadata.
-
-### Sound-engine architecture
-
-The most striking audio result is how little the interpreter changed. Both repositories' `audio/engine.asm` identify themselves as the entire sound engine, update once per frame, parse music commands, maintain eight software channel structures (four music and four sound-effect channels), and ultimately drive the four Game Boy audio channels. Both implementations handle duty, envelope, frequency, vibrato, noise sampling, channel muting, low-health sound, and fades through the same broad code.
-
-```mermaid
-flowchart LR
-    SONG[Song bytecode]
-    PARSE[ParseMusic]
-    STATE[Per-channel WRAM state]
-    FX[Vibrato / pitch / envelope / noise]
-    MIX[Music-SFX priority and routing]
-    APU[Game Boy audio registers]
-
-    SONG --> PARSE --> STATE --> FX --> MIX --> APU
-```
-
-Crystal therefore does not introduce a new synthesizer. It extends the music corpus and invokes new songs in new contexts.
-
-### Crystal's additional music
-
-Gold/Silver's song pointer table ends at `Music_PostCredits`. Crystal retains that ordering and appends ten entries:
-
-| Crystal-only pointer entry | Use |
-|---|---|
-| `Music_Clair` | Clair-related scene |
-| `Music_MobileAdapterMenu` | Japanese Mobile menu |
-| `Music_MobileAdapter` | Mobile connectivity |
-| `Music_BuenasPassword` | Buena's Password |
-| `Music_LookMysticalMan` | Eusine encounter |
-| `Music_CrystalOpening` | Revised opening |
-| `Music_BattleTowerTheme` | Battle Tower battle/context |
-| `Music_SuicuneBattle` | Legendary-beast/Suicune battle theme |
-| `Music_BattleTowerLobby` | Battle Tower lobby |
-| `Music_MobileCenter` | Japanese Mobile Center |
-
-The pointer table labels these explicitly as "new to Crystal."
-
-Bulbapedia independently notes that Crystal gives the legendary beasts a unique battle theme and presents it as the first core-series special legendary battle music.
-
-From a porting perspective, bringing Crystal music into Gold/Silver primarily requires assigning ROM space, importing sequence data, adding pointer/constants entries, and adding selection call sites. Replacing the audio engine is generally unnecessary. However, preserving existing numeric song IDs is wise because map headers, scripts, battle setup, radio state, and fades refer to those constants.
-
-## Bugs, compatibility, porting, and reverse-engineering timeline
-
-### Bug and quirk matrix
-
-| Category | Gold/Silver | Crystal | Engineering interpretation |
-|---|---|---|---|
-| Coin Case text terminator | Exploitable continuation can permit arbitrary code execution | Correct terminator | Parser/data correction |
-| First-save Hall of Fame | Can corrupt PC boxes | Guard and initialization added | Save-state precondition correction |
-| Lucky Number boxes | International boxes 10-14 omitted | Uses full box count | Localization constant corrected |
-| Surf onto NPC | Possible | Facing-object check added | Collision precondition corrected |
-| Cerulean Gym fishing | Enabled by map fish group | Disabled | Map-header data correction |
-| Reflect/Light Screen overflow | Incorrect | Fixed outside compatible link path | Context-dependent battle fix |
-| Present damage | Incorrect | Fixed outside compatible link path | Protocol-preserving fix |
-| Glacier Badge Special Defense | Bugged | Still bugged | Shared inherited defect |
-| Apricorn specialty balls | Multiple formula defects | Still defective | Shared inherited mechanics |
-| Beat Up synchronization | Vulnerable | Still vulnerable | Shared link-engine defect |
-| Secondary-effect 1/256 failure | Present | Present | Shared probability comparison defect |
-| Animated-sprite quirks | Not applicable | New animation-specific defects possible | Feature expansion creates new failure surface |
-
-The Gold/Silver and Crystal bug documents should be read together. The Gold/Silver document intentionally lists only bugs that Crystal fixed; any shared defects are documented in the Crystal repository instead.
-
-Crystal is thus more polished but not mechanically "corrected" in a comprehensive sense. A modern source port must choose a compatibility target:
-
- **Retail-faithful:** preserve all version-specific bugs and timing.
- **Crystal-faithful:** preserve Crystal's selective fixes and its link-mode exceptions.
- **Corrected Gen II:** repair documented defects, accepting that link compatibility and historical RNG traces may change.
- **Hybrid:** gate corrections behind flags or negotiate them between identical modified link peers.
-
-### ROM revisions and regional code
-
-The Crystal repository builds international v1.0, v1.1, and Australian releases. Its FAQ states that v1.1 corrected some issues in the initial international release, while the Australian build is based on v1.1 and censors gambling references. Thus "Crystal behavior" is not completely singular even within English-language retail ROMs.
-
-A serious test report should always state the target hash rather than merely "Pokémon Crystal." Otherwise, an observed difference may be edition-level, v1.0/v1.1-level, Australian localization, Japanese Mobile code, Virtual Console patching, emulator behavior, or an altered ROM.
-
-### Link and trade compatibility
-
-Gold, Silver, and Crystal share the Gen II Pokémon record length and battle/link architecture, allowing ordinary same-generation trading and battling. The retained two-byte record size, shared `REDMON_STRUCT_LENGTH` conversion constant for Time Capsule interaction, and synchronized battle RNG are all source-level evidence of compatibility-oriented design.
-
-However, three distinct notions of compatibility must not be conflated:
-
-| Compatibility type | Status |
-|---|---|
-| Pokémon record compatibility | Strong: same record length; Crystal fills reserved bytes |
-| Link protocol/battle simulation compatibility | Strong for retail games, partly because Crystal preserves old link behavior |
-| Whole-save-file compatibility | Weak: Crystal's SRAM organization and added state differ substantially |
-| ROM patch-address compatibility | Weak: bank layout and code placement differ |
-| Feature-source portability | Moderate: shared architecture helps, but dependencies are broad |
-| Gen I Time Capsule data compatibility | Supported through dedicated conversion structures and restrictions |
-| Modern transfer compatibility | Supported from 3DS VC releases through Poké Transporter and Pokémon Bank |
-
-Nintendo's support documentation lists the Virtual Console releases of Gold, Silver, and Crystal as compatible with Poké Transporter. Transfers proceed into Pokémon Bank and can then move onward to Pokémon HOME, but that modern path is not a raw Gen II save conversion and is effectively one-way at later stages.
-
-### Virtual Console modifications
-
-Crystal's save code contains an explicit `vc_hook` after Hall of Fame insertion. The hook sets the primary and backup GS Ball flags to make the GS Ball quest and Celebi encounter available, with compile-time assertions pinning the expected SRAM addresses and flag value.
-
-```asm
-vc_hook Enable_GS_Ball_mobile_event
-vc_assert BANK(sGSBallFlag) == $1
-vc_assert BANK(sGSBallFlagBackup) == $1
-```
-
-Source: [Crystal `engine/menus/save.asm`](https://github.com/pret/pokecrystal/blob/8e8f7e20052a596371a77022f0392c285e51bbf1/engine/menus/save.asm#L157-L167).
-
-This is a fascinating compatibility shim: the original international cartridge retained GS Ball-related structures but lacked the original Japanese distribution path, so the Virtual Console wrapper activates the event through a targeted runtime hook. The Pokémon Company confirms that the Virtual Console version permits the Celebi encounter at Ilex Forest's shrine.
-
-The pret repositories also contain `vc` build material, and community GitHub discussion has addressed preserving or generating Virtual Console patches. A port targeting 3DS VC behavior should therefore compare not only the retail ROM but the external patch/hook layer.
-
-### Japanese Crystal and mapper/SRAM concerns
-
-Crystal's SRAM source reserves several Mobile sections and explicitly comments that a Mobile Easy Chat initialization routine uses an "MBC30 bank" available to Japanese Crystal but inaccessible with ordinary MBC3 behavior. This is direct evidence that regional hardware assumptions matter when emulating or reproducing Japanese Mobile features.
-
-An implementation that supports only the common international MBC3-style SRAM/RTC configuration may run the international game correctly yet fail Japanese Crystal's extended Mobile storage accesses. Conversely, allocating the larger memory blindly does not implement Mobile Adapter protocols, timer behavior, ranking checksums, or server-era workflows.
-
-### Porting guidance
-
-The safest migration strategy between the two disassemblies is subsystem-oriented:
-
-| Port direction | Recommended approach | Main hazard |
-|---|---|---|
-| Gold <-> Silver data | Preserve shared engine; switch edition tables/assets | Conditional data references and event assumptions |
-| Crystal feature -> Gold/Silver | Import feature plus all WRAM/SRAM, graphics, script, audio, and menu dependencies | DMG/SGB fallback and bank-space pressure |
-| Gold/Silver behavior -> Crystal | Replace data or selectively restore old branch | Crystal story/event state may expect new semantics |
-| Gold/Silver save -> Crystal | Parse and rebuild symbolic fields | Relocated blocks and Crystal-only state |
-| Crystal save -> Gold/Silver | Strip Crystal state and preserve common Pokémon/player data | Caught metadata becomes opaque; Suicune/Battle Tower state has no target |
-| Retail battle fix | Gate by non-link mode or require identical modified peers | RNG/control-flow desynchronization |
-| Crystal graphics -> DMG-compatible engine | Create monochrome layouts or make build CGB-only | Palette attributes and animation timing |
-| Japanese Mobile feature port | Emulate mapper, extended SRAM, timer, and communication assumptions | Hardware and defunct-service dependencies |
-
-Bank space is a concrete constraint. The pokecrystal FAQ describes the international ROM as 2 MiB divided across banks and notes that adding features can overflow fixed bank placement, requiring sections to be moved through the linker script. Crystal's extra features already consume carefully arranged banks, so a port that compiles at the object level can still fail at link time.
-
-The deepest practical rule is: **port invariants before routines**. Before copying code, define the target's expected record lengths, bank-switch convention, WRAM variables, SRAM addresses, script command set, palette mode, RNG call contract, and link-mode semantics. Once those invariants match, most inherited Gen II routines are straightforward. Without them, a perfectly copied routine can read the wrong field, switch to the wrong bank, write outside a save block, or desynchronize a link battle.

-
-Gold and Silver launched in Japan on November 21, 1999 and in North America on October 15, 2000; Crystal followed in Japan on December 14, 2000 and internationally in 2001. Gold/Silver reached 3DS Virtual Console in September 2017 and Crystal followed in January 2018.
-
-The current reverse-engineering record is better described as an evolving evidence base than as a single "discovery date." pret's labels, comments, and bug documentation have accumulated over thousands of repository commits, while the exact-build hashes provide a stable anchor to the retail binaries. Crystal's repository currently has substantially more history and feature documentation than `pokegold`, reflecting its role as the community's principal Gen II hacking platform rather than evidence that Crystal's retail source was inherently better documented.
-
-### Final technical assessment
-
-Gold and Silver are functionally sibling configurations of one engine. Their meaningful differences are overwhelmingly table-, asset-, and version-flag-driven. Crystal preserves that engine's defining architecture but turns it into a more specialized platform: Color-only graphics, animated Pokémon, richer event scripting, expanded persistent state, Mobile-era infrastructure, Battle Tower contexts, caught metadata, additional music, and selective defect correction.
-
-At ASM level, the most consequential changes are not usually exotic algorithms. They are small branches with large semantic reach:
-
- a Battle Tower early return suppresses badge boosts;
- two reserved Pokémon bytes acquire caught metadata without changing record size;
- Suicune disappears from `InitRoamMons`;
- save blocks become reorganized and gain new persistent domains;
- a text terminator closes the Coin Case execution path;
- link-mode checks preserve old arithmetic to avoid desynchronization;
- a Virtual Console hook activates an otherwise inaccessible event;
- a Mobile timer branch attaches a new subsystem to the interrupt path.
-
-That pattern explains both Crystal's compatibility and its porting difficulty. It remains recognizably the Gold/Silver engine, but its new features are woven through banks, state structures, control-flow conditions, graphics timing, SRAM, scripts, and presentation. The code is cousin-shaped, not copy-paste-shaped: the classic reverse-engineering booby trap wearing a tiny Suicune hat.

-# ROM Extraction Notes
-
-There are two ROM-only extraction paths:
-
- The packaged app uses `src/import/RomImporter.lua` and
-  `src/import/RomExtractor.lua` on first boot.
- Developers can run `tools/build_data.py --rom <path> [--clean]` to generate
-  data in the source tree for audit and parity work.
-
-Both paths read only the supplied ROM and the checked-in
-`tools/rom_manifest.json`. Neither invokes RGBDS, Git, or a disassembly.
-
-## Validation
-
-Only the canonical US Pokemon Red ROM is supported. SHA-1 is checked before
-any cached output is removed or written.
-
-## Decoded Data
-
-| Area | ROM data |
-| --- | --- |
-| world | map headers, block maps, connections, warps, signs, objects |
-| tiles | tileset graphics, blocksets, collision, door and warp tile lists |
-| text | 2,584 text command streams and RAM/number substitutions |
-| Pokemon | names, stats, evolutions, learnsets, Dex data, compressed pictures |
-| battle | moves, detailed animations, OAM frames/tiles, effects, type chart, palettes, trainer parties/AI/pictures |
-| inventory | item names, prices, key-item flags, TM/HM data |
-| encounters | grass and water wild tables |
-| UI | fonts, icons, title/intro, trainer card, town map, slots, field effects |
-| audio | music, SFX and cry headers, channel programs, wave instruments |
-
-The Python and Lua picture decompressors implement the Gen 1 `pic` format.
-Graphics are converted to RGBA PNGs. OAM artwork uses transparent color 0;
-battle pictures use edge-connected white matting so white interior details
-remain visible.
-
-The in-app importer stores three audio ROM banks as a 48 KiB
-`programs.bin`. `src/core/ChipAudio.lua` interprets the channel bytecode and
-synthesizes music as a queueable stream; SFX and cries are synthesized on
-demand. This avoids shipping or generating a large WAV/OGG tree.
-
-## Metadata Boundary
-
-Names, dimensions, enum ordering, Lua script hooks, and hand-ported field
-behavior do not survive compilation in a form the Lua runtime can infer.
-Those relationships are bundled in `rom_manifest.json`. The manifest stores
-no dialogue strings, images, audio samples, or ROM bytes.
-
-`tools/make_rom_manifest.py` and `tools/verify_rom_data.py` are developer audit
-tools. They are not used by the packaged game.

-# Gen 2 link play: what it takes
-
-This is a design document, not a feature announcement. Gold cannot link today
-and nothing in this document changes that on its own. What it does is state
-honestly what Gen 2 link play requires, where the Gen 1 protocol in `src/link/`
-stops working on a Gen 2 record, what the cart itself did, and which pieces of
-the work are self-contained enough to have been built already.
-
-The short version: the transport, the handshake and the fingerprint are
-generation-agnostic or nearly so, and those are done. The party wire format is
-half done (a codec exists, nothing sends it). The trade session, the trade UI
-and the lockstep battle are not started, and each is a real piece of work.
-
-Read `docs/mod-api-gen2-compat.md` beside this: it is the reference for what a
-Gold mod may touch, and the link fingerprint's whole job is to hash exactly that
-surface.
-
-## 1. What Gen 1 link play is
-
-`src/link/` is nine files and about four thousand lines:
-
-| File | Job |
-| --- | --- |
-| `Net.lua` | lua-enet transport, LAN host/join plus a relay for online play. JSON messages, no game types. |
-| `CodeEntry.lua` | the online join code widget. |
-| `Handshake.lua` | the `hello` both peers exchange and the compatibility verdict drawn from the two of them. |
-| `Fingerprint.lua` | a deterministic digest of the link surface: the slice of merged Data whose value decides whether two lockstep simulations stay identical. |
-| `Protocol.lua` | mon serialization, the record-subset negotiation, and the trade session state machine. |
-| `LinkState.lua` | the LINK menu, pairing, and the trade/battle hand-off. |
-| `LinkBattle.lua` | lockstep battle: both machines run `src/battle/BattleState.lua` from mirrored perspectives on a shared seed, exchanging one action per turn and a per-turn state hash. |
-| `Tournament.lua` | bracketed online play over the relay. |
-| `Json.lua` | the encoder the wire and several unrelated callers share. |
-
-Only three of those nine are shaped around Gen 1 game content: `Fingerprint`,
-`Protocol` and `LinkBattle`. `Net`, `Json`, `CodeEntry` and most of `Handshake`
-never look at a Pokemon.
-
-## 2. What the cart did
-
-pokegold's link code is `engine/link/link.asm` (2508 lines), and it is worth
-being precise about, because several of the port's design questions have a cart
-answer.
-
-**Three rooms, one wire.** `wLinkMode` is `LINK_TIMECAPSULE`,
-`LINK_TRADECENTER` or `LINK_COLOSSEUM` (`constants/serial_constants.asm`).
-`LinkCommunications` branches once, at the top, on whether the mode is the Time
-Capsule: `Gen2ToGen1LinkComms` for the Time Capsule and `Gen2ToGen2LinkComms`
-for everything else (`engine/link/link.asm:33`). Everything after that branch is
-shared -- the same byte exchange serves trading and battling, and the mode only
-decides what is in the buffer and what the game does afterwards.
-
-**What crosses the wire, in order** (`Gen2ToGen2LinkComms`,
-`engine/link/link.asm:202`):
-
-1. `SERIAL_RN_PREAMBLE_LENGTH + SERIAL_RNS_LENGTH` bytes: the shared battle
-   RNG state. Seven preamble bytes and ten seeds.
-2. `SERIAL_PREAMBLE_LENGTH + NAME_LENGTH + (1 + PARTY_LENGTH + 1) + 2 +
-   (PARTYMON_STRUCT_LENGTH + NAME_LENGTH * 2) * PARTY_LENGTH + 3` bytes: the
-   player name, the party count and species list, the **trainer ID**, six party
-   structs, six OT names and six nicknames.
-3. `SERIAL_PATCH_LIST_LENGTH` bytes: the patch list (see below).
-4. In the Trade Center only, the mail block: six mail messages then six mail
-   metadata structs (`Link_PrepPartyData_Gen2`, `engine/link/link.asm:810`).
-
-**The shared PRNG is the whole trick behind lockstep.** `_BattleRandom`
-(`engine/battle/core.asm:6650`) refuses the normal RNG whenever `wLinkMode` is
-non-zero and pulls from `wLinkBattleRNs` instead: ten seeds, each advanced by
-`a[n+1] = (a[n] * 5 + 1) % 256` when the stream runs out, with the count in
-`wLinkBattleRNCount`. Both machines exchange those ten bytes once, before the
-battle, and never again -- the external-clock side adopts the internal-clock
-side's numbers (`Link_CopyRandomNumbers`, `engine/link/link.asm:1115`). The port
-does the same thing with a Park-Miller stream seeded by the host
-(`LinkBattle.makeRng`), which is the same idea in a different arithmetic.
-
-**The patch list exists because the wire has reserved bytes.**
-`SERIAL_NO_DATA_BYTE` (`$fe`) may not appear in the payload, so
-`FixDataForLinkTransfer` (`engine/link/link.asm:556`) walks the party block,
-replaces every `$fe` with `$ff`, and records the offsets it touched in a
-200-byte list that ships alongside. Mail gets its own smaller version of this in
-`Link_PrepPartyData_Gen2`. The port's wire is JSON over enet and has no reserved
-bytes, so this whole mechanism has no analogue and needs none. It is worth
-knowing about only so nobody reimplements it by accident.
-
-**The Time Capsule is the cart's own answer to a cross-generation link.**
-`CheckTimeCapsuleCompatibility` (`engine/link/link.asm:1970`) refuses the party
-outright for exactly three reasons, and returns which one in `wScriptVar`:
-
-1. a species at or above `JOHTO_POKEMON` (`constants/pokemon_constants.asm:168`,
-   the 152 boundary),
-2. a move above `STRUGGLE`, i.e. any move Gen 1 does not have,
-3. any party member holding mail.
-
-If the party passes, `Link_PrepPartyData_Gen1` (`engine/link/link.asm:640`)
-rewrites every mon into the 44-byte `REDMON_STRUCT_LENGTH` layout:
-`ConvertMon_2to1` remaps the species index through `Pokered_MonIndices`
-(`engine/link/time_capsule_2.asm:1`), the Special stat is recomputed from
-`KantoMonSpecials` because Gen 1 has one Special and Gen 2 has two, and
-Magnemite and Magneton are shipped as pure Electric because their typing changed
-(`engine/link/link.asm:731`). Coming the other way, `Link_ConvertPartyStruct1to2`
-(`engine/link/link.asm:930`) reads the Gen 1 catch rate byte as the held item
-slot -- garbage, which is why `TimeCapsule_ReplaceTeruSama`
-(`engine/link/link.asm:1078`) maps the handful of catch rates that collide with
-real items through `data/items/catch_rate_items.asm` and turns everything else
-into a Berry. `ValidateOTTrademon` (`engine/link/time_capsule.asm:1`) then
-re-checks the incoming mon's types against the local base data and refuses
-anything that does not agree, with Magnemite and Magneton carved out again.
-
-The lesson the port should take from all of that: a cross-generation link is not
-a compatibility mode, it is a lossy conversion with a validator on each end, and
-the cart wrote roughly 400 lines for it. Refusing the pairing is the honest
-default until somebody wants to write those 400 lines.
-
-## 3. Where the Gen 1 protocol breaks on a Gen 2 record
-
-`Protocol.packMon` / `Protocol.unpackMon` are shaped around
-`src/pokemon/Pokemon.lua`. Against `src/battle/gen2/Mon.lua`, every one of these
-is wrong:
-
-| Gen 1 assumption | Gen 2 reality | Where |
-| --- | --- | --- |
-| `mon.exp` | `mon.experience` | `Mon.new`, `Mon.gainExperience` |
-| five DVs including `special` | four rolled DVs (`attack`/`defense`/`speed`/`special`) with `hp` **derived** from their low bits | `Mon.hpDV` |
-| `special` is one stat | `specialAttack` and `specialDefense` are two stats off one DV | `Mon.stats` |
-| `statExp` has five words | five words still, but the fifth feeds both special stats | `Mon.stats` |
-| no held item | `mon.item` decides damage, healing and flinching | `src/battle/gen2/Battle.lua` `heldEffect` |
-| stats recomputed with `src/pokemon/Stats.lua` | must go through `Mon.stats`, which is a different formula shape | `Mon.stats` |
-| exp curve via `src/pokemon/Growth.lua` (code) | curve coefficients are **data**, at `data.pokemon.growthRates` | `Mon.experienceForLevel` |
-| `mon.status` is `"SLP"` / `"PSN"` / `"BRN"` / `"PAR"` / `"FRZ"` | `"sleep"` / `"poison"` / `"burn"` / `"paralyze"` / `"freeze"` / `"toxic"` | `src/battle/Status.lua:62` vs `src/battle/gen2/Battle.lua:65` |
-| `mv.ppUps` | Gen 2 has no PP Ups modelled yet; moves carry `id`, `pp`, `maxPp` | `Mon.movesAtLevel` |
-| nothing else on the mon | `happiness`, `pokerus`, `caughtLevel`, `isEgg`/`eggSteps`, and the derived `shiny` / `gender` / `unownLetter` | `Mon.new` |
-| mail does not exist | mail is a **separate** block keyed by party slot, not a mon field | `src/core/gen2/Mail.lua:84`, and the cart agrees (`Link_PrepPartyData_Gen2`) |
-
-The status spelling is the sharpest of these. `packMon` puts `mon.status` on the
-wire verbatim and `unpackMon` keeps it verbatim, so a shared codec would move
-`"PSN"` onto a Gold party where nothing recognises it -- a mon that arrives
-"poisoned" and never takes poison damage. Any Gen 2 codec has to be a separate
-function with the generation baked into it, not a Gen 1 function with extra
-optional keys.
-
-Two things are *not* a problem, and it is worth saying so:
-
- **Species and move ids are shared name spaces.** Both generations key
-  `data.pokemon` and `data.moves` by the same `TOTODILE` / `TACKLE` strings, so
-  the wire never needs the cart's index remap (`ConvertMon_2to1`). Ids, not
-  bytes, is what makes the port's protocol simpler than the cable's.
- **The derived fields do not travel.** `shiny`, `gender` and `unownLetter` are
-  all functions of the DVs (`Mon.isShiny`, `Mon.gender`, `Unown.letterFromDVs`),
-  so the receiver recomputes them and a tampered packet cannot claim a shiny it
-  did not roll. Same reasoning as `unpackMon` recomputing stats.
-
-`LinkBattle.lua` breaks in a larger way. It calls
-`BattleState.makeBattler`, `src/battle/TurnOrder.lua` and Gen 1's damage
-pipeline directly. Gold's battle is `src/battle/gen2/Battle.lua`, a different
-object with a different event shape. The one piece of good news is that
-`Battle.new` already takes `opts.random` (`src/battle/gen2/Battle.lua:220`) --
-the injection seam a lockstep battle needs is there and does not have to be cut.
-
-## 4. The wire format for Gen 2
-
-Message types stay the ones `Protocol.lua` already documents (`hello`,
-`records`, `party`, `pick`, `confirm`, `action`, `event`, `bye`). Gen 2 adds
-fields, never renames -- the same rule the mod seams follow.
-
-**`hello`** gains one field, `generation` (1 or 2). A peer that omits it is
-generation 1 by construction: no released build has ever had Gen 2 link, so
-absent means Red/Blue/Yellow. This is implemented.
-
-**`party`** carries a list of packed mons whose shape is the Gen 2 one:
-
-```
-{ species, level, experience, hp, status, nickname,
-  dvs = { attack, defense, speed, special },   -- hp derived
-  statExp = { hp, attack, defense, speed, special },
-  moves = { { id, pp } ... },
-  item, happiness, pokerus, caughtLevel,
-  ot, otId, isEgg, eggSteps, extra }
-```
-
-and, in a trade, a parallel `mail` array indexed by the same wire position --
-separate exactly as `Link_PrepPartyData_Gen2` keeps it separate, because mail is
-SRAM the cart copies out of `sPartyMail`, not part of the party struct. The
-codec for the mon half is implemented; the mail half is not.
-
-**`records`** gains a third map, `heldItems`, beside `pokemon` and `moves`, so a
-subset trade can refuse a mon whose held item the other game would rebuild
-differently. Implemented.
-
-**`action` / `event`** for a lockstep Gen 2 battle are not designed here, because
-the design is downstream of a decision nobody has made yet: whether
-`src/battle/gen2/Battle.lua` grows a "replay these two actions" entry point or
-whether the link battle drives it through the same UI path a local battle uses.
-Guessing at a message shape before that is exactly the half-built protocol this
-document is meant to avoid.
-
-## 5. The fingerprint on Gold
-
-The fingerprint is the one part of the design that is fully answerable today,
-because it depends only on what a Gold mod can reach, and `src/mods/Schemas.lua`
-answers that exhaustively.
-
-The Gen 1 surface is species, moves, the type chart, statuses, move effects,
-constants and mod-declared link fields. The Gen 2 surface is the same idea over
-different tables, plus one registry Gen 1 does not have:
-
-| What | Gen 1 | Gen 2 | Why it is surface |
-| --- | --- | --- | --- |
-| species | `data.pokemon` | `data.pokemon` (Gen 2 shape) | base stats decide every damage roll; `evolutions` decides what a traded mon becomes |
-| exp curves | code (`src/pokemon/Growth.lua`) | `data.pokemon.growthRates` | the level a traded mon's experience buys |
-| moves | `data.moves` | `data.moves`, **plus `effectChance`** | Gen 2 stores the secondary-effect odds per move rather than per effect |
-| type chart | `data.type_chart` | same, **plus `foresightMatchups`** | Foresight rewrites Ghost's immunities mid-battle |
-| statuses | `data.statuses` | `data.gen2Statuses` | `statPenalty`, `cureOnSwitch`, `beforeMovePriority` |
-| move effects | `data.move_effects` | `data.gen2MoveEffects` | which effect is primary, secondary, or accuracy-checked |
-| held items | -- | `data.gen2HeldItems` | Leftovers, King's Rock, the type boosters: pure battle math, and the item travels with a traded mon |
-| link fields | `data.link_fields` | none (gated) | a mod-declared extra mon field; see below |
-
-Deliberately **not** hashed on either generation, and the reasoning is the same
-in both:
-
- Names, dex entries, learnsets, TM/HM lists, sprite paths and `source`. None of
-  them changes a battle turn or a trade rebuild, and sprite paths differ between
-  two identical installs.
- `catchRate` (#511). A ball thrown in a link battle is refused; hashing it split
-  Red/Blue from Yellow over two bytes.
- Balls and item effects. Link battles allow no bag items on either cart.
- `data.gen2Constants`. It is the ROM's ordered name lists -- `mapOrder`,
-  `spriteOrder`, `speciesOrder`, `heldEffectOrder` -- and it is an *index* space.
-  Every dispatch in the Gen 2 simulation goes by name (`Battle.heldEffect`
-  compares `record.heldEffect` strings, `moveEffectRecordFor` keys by
-  `EFFECT_*`), so reordering a constants list moves no battle math. Hashing it
-  would split two peers over a list neither of them dispatches on.
- Breeding data (`eggGroups`, `eggMoves`, `eggSteps`). The Day-Care is local.
-  There is no link breeding and an egg's contents are decided before it is
-  traded.
- Everything in the Gen 2-only registries that is not `held_items`:
-  `phone_contacts`, `decorations`, `apricorns`, `landmarks`, `radio_channels`.
-  None of them can be observed from inside a link session.
-
-`genderRatio` **is** hashed, unlike anything in the breeding block, because Gen 2
-has Attract and a gender disagreement is a battle-math disagreement.
-
-`link_fields` stays gated on Gen 2 (`Schemas.GEN2`). It is a mod's declaration
-that an extra mon field must survive the wire, and it can only be un-gated once
-there is a Gen 2 mon wire format with a session behind it. A registry that hashes
-into the fingerprint but that no packer reads would be a lie the fingerprint
-tells.
-
-The hook keeps its Gen 1 name and its Gen 1 arity. `link.fingerprint` is called
-as `(data, mods)` on both generations, and the generation is captured in the
-vanilla closure rather than passed as a third argument -- a Gen 1 mod that wraps
-the hook and forwards `nxt(data, mods)` therefore works verbatim on Gold, which
-a third argument would have quietly broken.
-
-## 6. Cross-generation pairing
-
-`Handshake.checkCompat` refuses a pairing whose two `generation` fields differ,
-with reason `generation_mismatch`, before any other check. This is deliberately
-a refusal and not a Time Capsule: section 2 costs roughly 400 lines of lossy
-conversion plus two validators, and shipping a menu that pairs a Gold game with a
-Red one and then rebuilds a Cyndaquil as whatever species index 155 happens to
-be in Red would be worse than refusing.
-
-If somebody does want the Time Capsule later, the cart's own rules are the spec,
-and the port has an advantage the cart did not: ids rather than indices, so
-`ConvertMon_2to1`'s remap table is unnecessary. What remains is real work:
-refuse species above the Kanto 151, refuse moves Gen 1 lacks, refuse held items
-and mail, fold `specialAttack`/`specialDefense` back into one Special
-(`KantoMonSpecials`, `data/pokemon/gen1_base_special.asm`), and re-validate types
-on arrival with Magnemite and Magneton carved out.
-
-## 7. What is built, and what is left
-
-**Built (this change).**
-
- `Fingerprint.generationOf(data)`: reads `data.type_chart.generation`, then the
-  presence of the Gen 2-only Data namespaces, so the digest never has to be told
-  which game it is running in.
- A Gen 2 link surface in `Fingerprint.lua`, tagged `[gen2]` so a Gen 2 digest
-  can never collide with a Gen 1 one, covering the table in section 5.
- `Fingerprint.records(data, kind, generation)` for `pokemon`, `moves` and
-  `held_items` on Gold, which is what a subset trade negotiates on.
- `Handshake.hello` carries `generation`; `checkCompat` refuses a cross-generation
-  pairing; `describe` explains it in the screen's own voice.
- `held_items` counts as link surface for `Handshake.linkModified`, so a Gold mod
-  that gives Leftovers a different heal is correctly locked out of online play.
-  `growth_rates` counts too, and for a reason worth stating: a curve is an
-  `expForLevel` function, so the fingerprint serializes it as `?` and cannot
-  hash it at all. `Mon.growthFor` prefers the merged registry over the
-  extractor's coefficient rows, so a mod declaring `affects_link = false` could
-  otherwise rewrite every curve -- changing what level a traded mon's experience
-  buys -- and be caught by neither the digest nor the online gate.
- `Protocol.packMon2` / `unpackMon2`: the Gen 2 party-struct codec, with the
-  receiver recomputing stats, experience, shininess and gender from real species
-  data the way `unpackMon` does. Nothing sends it yet.
- `Protocol.recordsMessage` and `eligibleParty` understand held items, and
-  `TradeSession:_negotiate` builds our own side of the comparison by calling
-  `recordsMessage` rather than open-coding a subset of it. That is not a
-  refactor: the open-coded version left `heldItems` off our side only, and both
-  held-item arms of `eligibleParty` are guarded on our own map, so the whole
-  check was unreachable from the only caller that matters.
-
-**Not built.** Sized as honestly as I can:
-
-| Piece | Size | Why it is not here |
-| --- | --- | --- |
-| Mail on the wire | small (1-2 days) | needs `Mail.state(save).party` packed as a parallel array and the receiver writing it into its own slot; no consumer until the trade session exists |
-| Gen 2 trade session | medium (about a week) | `TradeSession` is generic in shape but `apply` calls `src/world/PikachuFollower`, Gen 1 pokedex fields and Gen 1 trade evolutions; Gold needs `src/core/gen2/TradeAnim.lua`, `src/core/gen2/Evolution.lua` (`EVOLVE_TRADE`) and the Gen 2 pokedex |
-| Gold LINK menu and trade UI | medium (about a week) | Gold's menus are `src/ui/gen2/`, its text box is Gen 2 chrome, and the Cable Club script needs the receptionist path; `LinkState.lua` draws with Gen 1 `TextBox` throughout |
-| Gen 2 lockstep battle | large (several weeks) | needs a deterministic-replay entry point into `src/battle/gen2/Battle.lua`, a Gen 2 action/event encoding, and a state hash over a much larger volatile-status set than Gen 1's; the `opts.random` seam exists, nothing else does |
-| Time Capsule | large | section 6 |
-| `link_fields` on Gen 2 | small, but blocked | needs the trade session first |
-
-The order matters: mail, session and UI are the trade half and can ship without
-the battle half, exactly as the cart's Trade Center and Colosseum are separate
-rooms. A Gold LINK menu that offers only TRADE is a complete feature. A Gold
-LINK menu that offers BATTLE before the lockstep battle exists is the failure
-this document was written to prevent.

-## Pipeline
-
-| Piece | Role |
-| --- | --- |
-| `src/import/Rom.lua` (`decompressLz3`) | Gen 2 graphics compression (`home/decompress.asm`) |
-| `tools/make_gold_manifest.py` → `tools/rom_manifest_gold.json` | pret/pokegold constants + `pokegold.sym` |
-| `src/import/RomExtractorGen2.lua` | Gen 2 extract (dispatched from `RomImporter` when `version == "gold"`) |
-| `src/core/GameVersion.lua` | `gold` entry (`gold/` cache, `_gold` saves) |

-| `src/core/gen2/Save.lua` | `save_gold.lua`, beside the Gen 1 saves |
-| `src/ui/gen2/` | Intro menu, naming keyboard, START menu + every submenu, battle screen |
-| `src/battle/gen2/` | Damage, stats/experience, HP bar, turn engine, catching, encounters |
-| `src/render/GbcPalette.lua` | One shader: a 4-shade sheet through a GBC palette |

-
-## Play
-
-Launcher → Gold tab → Play opens `Game2` (`src/core/Game2.lua`):
-
- Copyright → GameFreak Presents → GS intro stub → title (colored tilemap,
-  scrolling clouds, Ho-Oh flap, trails) → Oak speech (Marill cry + shrink)
-  → name pick → `src/world/gen2/World`
- Drivers (`POKEPORT_DRIVER`) skip cinema straight to the map
- New Bark Town with Johto tileset + roof overlay (outdoors only)
- Walk on `COLL_*` permissions; doors / stairs / carpets
- Elm's lab: scene walk-in, starter balls (`givepoke` + cutscene moves),
-  Elm phone number, aide Potion on exit (`verbosegiveitem`)
- Connected neighbor strips + seamless edge crossings (Route 29 / 27)
- Survey zoom (`-` / `=` / wheel / `4`)
- Chris + map/neighbor NPCs; `SPRITEMOVEDATA_*` walk / spin / stand
- New-game flags hide story NPCs (e.g. lab cop)
- A: talk to facing NPC or read `BGEVENT_READ` signs via Gen 2 VM + TextBox
-
-Escape is START, not quit: quitting is the START menu's QUIT row and the
-intro menu's EXIT GAME.  Title / map music and script SFX/cries use the Gen 2
-channel driver.
-
-## Colour
-
-Gen 2 is CGB-native, so colour is part of a tile's identity rather than a tint
-over a 4-shade image.  `engine/gfx/color.asm` LoadMapPals is ported whole in
-`src/world/gen2/Palettes.lua`:
-
-1. the clock hour picks a daytime (`engine/rtc/rtc.asm` TimesOfDay), which a
-   map's own `PALETTE_*` can override (`ReplaceTimeOfDayPals`)
-2. `EnvironmentColorsPointers[environment][daytime]` names eight entries in the
-   shared `TilesetBGPalette` pool
-3. outdoors only, `RoofPals[mapGroup]` overwrites `PAL_BG_ROOF` colours 1-2 --
-   one roof tile sheet, a different colour per town
-4. each tile's slot comes from its tileset's `PalMap`, and each OW sprite's OBJ
-   palette from `MapObjectPals[daytime]` plus its own `PAL_OW_*`
-
-The map bake runs one shader pass per BG slot (eight per map) rather than one
-per tile, and re-bakes when the clock rolls into a new daytime.
-`POKEPORT_GOLD_HOUR=21` pins the hour for screenshots.
-
-## Still to do
-
-About fifty of AI_Smart's seventy per-effect handlers are unwritten, fishing
-and headbutt have engine support but no input path, and Mart, the summary
-screen, `.sav` interchange, Silver and mod-replaceable Gen 2 screens are all
-still open.

-`POKEPORT_IMPORT_TRACE=1` prints each of the 26 stages as it starts, and a
-headless import that fails now says so and exits non-zero rather than sitting
-in an error state that looks exactly like a hang.
-
-A Gold cache without `palettes.lua`, `moves.lua`, `encounters.lua`,
-`trainers.lua`, `pokedex.lua`, `landmarks.lua`, `icons.lua`, `menu_gfx.lua`,
-`intro.lua`, `std_scripts.lua` or `battle/hud/*.png` needs a re-import -- as
-does one whose back pics are still the front pic's size rather than 48x48 (see
-below), and one whose trainer classes have no `encounterMusic` (the sixth
-pass added `TrainerEncounterMusic` to the manifest, so the manifest has to be
-regenerated as well).  So does one whose `text.lua` has no `labels` table: that
-is the by-name seed for the text no script pointer reaches (the Day-Care and
-breeding block, the mart conversation, the Hall of Fame headers), and it needs
-a regenerated manifest too, because the seed reads those symbols by name.
-
-## Traps this port has already fallen into
-
-Worth knowing before touching the extractor:
-
- **Back pics are always 6x6 (48x48).**  `BASE_PIC_SIZE`'s low nibble describes
-  the *front* pic only, so decoding a back at it reads the wrong tile count in
-  the wrong number of columns and produces garbage.
- **`#`, `<POKE>` and `<PKMN>` have no font tile.**  They are compression bytes
-  ($54/$24/$4a) that PlaceString expands; the manifest charmap has to expand
-  them or "#DEX" renders as "DEX".
- **FishGroups has no row for FISHGROUP_NONE**, so a group's row is its id minus
-  one.  Walking the constant list from the top reads every row shifted.
- **Trainer groups have no end marker** -- the next group's label follows
-  immediately -- so a party scan needs the class's own member list to bound it.
- **Pokedex entries are spread over four banks** and the cart derives the bank
-  arithmetically; take each species' own symbol instead.
- **`EvosAttacksPointers` is `dw`, not `dba`**: the blobs share the table's bank.
- Item ids past NUM_ITEMS (the TMs and HMs) have no ItemNames row; their name is
-  their TM number.
- **`TrainerClassAttributes` rows are SEVEN bytes**, not eight:
-  `NUM_TRAINER_ATTRIBUTES` is `_RS` after three `rb` and two `rw`.  An
-  eight-byte stride walks one byte further off with every class, so the AI
-  flags come out as noise for everything past the first trainer -- and it
-  produces plausible values rather than an error, which is how it survived two
-  passes.  The row is {item1, item2, baseMoney, aiLo, aiHi, switchLo,
-  switchHi}: the base money is byte THREE.
- **`dba_pic` does not store the real bank.**  For the three "Pics" sections
-  that sit above the 8-bit-friendly range it writes `$13`, `$14` or `$1f`, and
-  `FixPicBank` (engine/gfx/load_pics.asm) maps those back to `$1f`, `$20` and
-  `$2e`.  Any table of pic pointers -- `PokemonPicPointers`,
-  `UnownPicPointers`, `TrainerPicPointers` -- needs that mapping, or the read
-  lands in a completely different bank.
- **A pic can run over the top of its bank.**  `GetLZByte` bumps the bank and
-  drops back to `$4000` when the read pointer passes `$8000`, so a compressed
-  pic near the top of a bank keeps going into the next one; slicing only to
-  `$8000` stops short of nine of the Unown letters.
- **`BattleAnimObjects` rows are SIX bytes**, because `BATTLEANIMOBJ_LENGTH` is
-  `_RS - 1` -- the struct's runtime INDEX byte is not in the table.
- **Unown has no `PokemonPicPointers` row of its own**; its twenty-six forms
-  come out of `UnownPicPointers` instead, and letter A stands in for the
-  species.

-# ASM Walk output format
-
-Every `section-NN-*.md` in this folder follows the structure below. The goal is a
-single place a bot author can look at to answer "for this stretch of the
-walkthrough, which maps, warps, objects, scripts, flags, items and trainers are
-involved, and where in the pokegold disassembly do they live?"
-
-Conventions:
-
- Disassembly paths are written relative to the pokegold checkout root, e.g.
-  `maps/NewBarkTown.asm`, `data/maps/maps.asm`, `constants/event_flags.asm`.
- Port paths are written relative to this repo root, e.g. `src/world/gen2/Map.lua`.
- Coordinates are the raw asm values (map-block coordinates as written in the
-  `warp_event` / `object_event` / `bg_event` rows), not screen pixels.
- Anything not verified by opening the file is omitted rather than guessed. If a
-  walkthrough claim could not be located in the asm, it goes under
-  "Unresolved / verify by hand".

-clearing `EVENT_PLAYERS_HOUSE_MOM_2`, which swaps in the three time-of-day Moms
-on the next map load.

-**Scripts of interest**
-
- `MeetMomScript` (the whole Pokegear beat, `maps/PlayersHouse1F.asm:21`):
-  1. `applymovement PLAYER, PlayersHouseDownstairsMovement` (one `step DOWN`, i.e. off the stair tile).
-  2. `playmusic MUSIC_MOM`, `turnobject PLAYERSHOUSE1F_MOM1, UP`, `showemote EMOTE_SHOCK, PLAYERSHOUSE1F_MOM1, 15`.
-  3. `applymovement PLAYERSHOUSE1F_MOM1, MomWalksToPlayerMovement` (`slow_step RIGHT, RIGHT, UP`: (7,3) -> (9,2), beside the player at (9,1)).
-  4. `writetext ElmsLookingForYouText`, `getstring STRING_BUFFER_4, PokegearName` ("#GEAR"), `scall PlayersHouse1FReceiveItemStd` -> `jumpstd ReceiveItemScript` (`engine/events/std_scripts.asm:656`).
-  5. `setflag ENGINE_POKEGEAR`, `setflag ENGINE_PHONE_CARD`, `addcellnum PHONE_MOM`.
-  6. `setscene SCENE_PLAYERSHOUSE1F_NOOP`, `setevent EVENT_PLAYERS_HOUSE_MOM_1`, `clearevent EVENT_PLAYERS_HOUSE_MOM_2`.
-  7. `special SetDayOfWeek`, then the DST loop: `IsItDSTText` -> `yesorno` -> `special InitialSetDSTFlag` / `special InitialClearDSTFlag`, each confirmed by a second `yesorno` that loops back to `.SetDayOfWeek` on "no".
-  8. Phone-instructions branch (`.KnowPhone` / `.ExplainPhone`, both fall into `.FinishPhone`), then `applymovement PLAYERSHOUSE1F_MOM1, MomWalksBackMovement` and `special RestartMapMusic`.
-  Crucially the #GEAR is **not** an inventory item: it is two engine flags. There
-  is no `giveitem` in this script.
- `MomScript` (talking to Mom afterwards): checks, in order,
-  `EVENT_FIRST_TIME_BANKING_WITH_MOM` -> `EVENT_TALKED_TO_MOM_AFTER_MYSTERY_EGG_QUEST`
-  -> `EVENT_GAVE_MYSTERY_EGG_TO_ELM` -> `EVENT_GOT_A_POKEMON_FROM_ELM`; in this
-  section all four are clear so it prints `HurryUpElmIsWaitingText`. The
-  `special BankOfMom` path is not reachable yet.

-  (5,2)), `turnobject ELMSLAB_ELM, LEFT`, `writetext ElmText_Intro` (the Mr.
-  Pokemon errand speech), then `setscene SCENE_ELMSLAB_CANT_LEAVE`.
- `CyndaquilPokeBallScript` / `TotodilePokeBallScript` / `ChikoritaPokeBallScript`:
-  identical shape. `checkevent EVENT_GOT_A_POKEMON_FROM_ELM` -> if set, just

-  - Cyndaquil: `readvar VAR_FACING` / `ifequal RIGHT, ElmDirectionsScript` (skips the walk if you took it from the left side), else `AfterCyndaquilMovement` = LEFT, UP.
-  - Totodile: `AfterTotodileMovement` = LEFT, LEFT, UP.
-  - Chikorita: `AfterChikoritaMovement` = LEFT, LEFT, LEFT, UP.

-  `setevent EVENT_RIVAL_CHERRYGROVE_CITY`,
-  `setscene SCENE_ELMSLAB_AIDE_GIVES_POTION`,
-  `setmapscene NEW_BARK_TOWN, SCENE_NEWBARKTOWN_NOOP`.
-  That last opcode is what removes the teacher gate.
- `AideScript_GivePotion` (reached by the (4,8)/(5,8) coord events once the scene
-  is 5): `writetext AideText_GiveYouPotion`, `verbosegiveitem POTION`,
-  `AideText_AlwaysBusy`, `setscene SCENE_ELMSLAB_NOOP`. One-shot, gated by the
-  scene id rather than an event flag.
- `LabTryToLeaveScript`: the "you cannot walk out yet" push-back described above.
- `ElmsLabHealingMachine` (bg_event at (2,1)): before
-  `EVENT_GOT_A_POKEMON_FROM_ELM` it just prints text; after, it offers a
-  `yesorno` -> `special HealParty`, `setval HEALMACHINE_ELMS_LAB`,
-  `special HealMachineAnim`. Free healing point for a bot from this section on.
- `ProfElmScript`: long check chain. In this section every branch falls through
-  to `writetext ElmText_LetYourMonBattleIt` (after the starter) or
-  `ElmDescribesMrPokemonScript`. The `ElmGiveEverstoneScript` arm needs
-  `EVENT_SHOWED_TOGEPI_TO_ELM`; the Master Ball arm needs `ENGINE_RISINGBADGE`;

-Note the FAQ's move lists are aspirational (they mix level-up moves with HM03 /
-HM04). At the moment you receive it the starter knows exactly its two level-1
-moves; Cyndaquil does **not** have Ember yet at L5.

-## 3. Blockers and gates
-
-| Gate | Enforced by (file:label) | Requirement | Unlock condition |
-|---|---|---|---|
-| Clock must be set before the world exists | `engine/menus/intro_menu.asm:494` `OakSpeech` -> `farcall InitClock` (`engine/rtc/timeset.asm:4`); default hour is 10 (`ld a, 10 ; default hour = 10 AM`) | hour then minute then a `YesNoBox` confirm each | answering "yes" to both confirmations |
-| Player must be named | `engine/menus/intro_menu.asm` `NamePlayer` -> `ShowPlayerNamingChoices` / `StorePlayerName` | pick a preset or type a name | any accepted name |
-| Cannot walk out of Elm's Lab before the errand speech ends | `maps/ElmsLab.asm` coord events (4,6) and (5,6) under `SCENE_ELMSLAB_CANT_LEAVE`, script `LabTryToLeaveScript` | scene id must leave 1 | `ElmDirectionsScript`'s `setscene SCENE_ELMSLAB_AIDE_GIVES_POTION` - i.e. take a starter |
-| Cannot leave New Bark Town west toward Route 29 | `maps/NewBarkTown.asm` coord events (1,8) and (1,9) under `SCENE_NEWBARKTOWN_TEACHER_STOPS_YOU`, scripts `NewBarkTown_TeacherStopsYouScene1/2` | scene id must leave 0 | `ElmDirectionsScript`'s `setmapscene NEW_BARK_TOWN, SCENE_NEWBARKTOWN_NOOP` |
-| Aide's Potion is scene-gated, not flag-gated | `maps/ElmsLab.asm` coord events (4,8)/(5,8), `AideScript_GivePotion` | be on scene 5 and step on x=4 or 5, y=8 | script itself does `setscene SCENE_ELMSLAB_NOOP` |
-| Everstone (listed by the FAQ under New Bark Town) | `maps/ElmsLab.asm:63,338-347` `ElmCheckEverstone` / `ElmGiveEverstoneScript` | `EVENT_SHOWED_TOGEPI_TO_ELM`, which needs a hatched Togepi in the party (`special FindPartyMonThatSpeciesYourTrainerID`) | many sections later |
-
-No HM field-move gate applies in this section: nothing under
-`engine/overworld/` (cut/surf/strength/whirlpool/waterfall/flash/fly) is
-consulted between the bedroom and the starter.

-## 4. Bot checklist
-
-| # | Map | Target | Intent | Precondition | Postcondition |
-|---|---|---|---|---|---|
-| 1 | - (main menu) | NEW GAME | menu select | fresh save | `NewGame` runs `ResetWRAM` |
-| 2 | - (`InitClock`) | hour, then minute, then yes/no per field | menu | in `OakSpeech` | RTC base written; default hour 10 |
-| 3 | - (`NamePlayer`) | any name | naming screen | after `OakText6` | `wPlayerName` set |
-| 4 | `PLAYERS_HOUSE_2F` | spawn (3,3) | - | `SPAWN_HOME` | `MAPCALLBACK_NEWMAP` runs `InitializeEventsScript` once; `EVENT_INITIALIZED_EVENTS` set |
-| 5 | `PLAYERS_HOUSE_2F` | warp 1 at (7,0) | walk onto | - | now on `PLAYERS_HOUSE_1F` warp 3 (9,0) |
-| 6 | `PLAYERS_HOUSE_1F` | (scene 0 auto-fires) | wait / mash A through `MeetMomScript` | `wPlayersHouse1FSceneID` == 0 | `ENGINE_POKEGEAR`, `ENGINE_PHONE_CARD`, `PHONE_MOM`, `EVENT_PLAYERS_HOUSE_MOM_1`, scene -> 1 |
-| 6a | `PLAYERS_HOUSE_1F` | DST `yesorno` pair | answer, then confirm | inside `MeetMomScript` | answering "no" to the confirm loops back to `.SetDayOfWeek` - a bot must confirm, not just answer |
-| 7 | `PLAYERS_HOUSE_1F` | warp 1 (6,7) or warp 2 (7,7) | walk onto | - | `NEW_BARK_TOWN` at warp 2 (13,5) |
-| 8 | `NEW_BARK_TOWN` | object `NEWBARKTOWN_RIVAL` at (3,2) | talk (optional) | rival visible while `EVENT_RIVAL_NEW_BARK_TOWN` clear | pushed one cell DOWN + a `jump_step DOWN`; **no flag set**, skippable |
-| 9 | `NEW_BARK_TOWN` | warp 1 at (6,3) | walk onto | avoid (1,8)/(1,9) until step 12 | `ELMS_LAB` at warp 1 (4,11) |
-| 10 | `ELMS_LAB` | (scene 0 auto-fires) | wait / mash A | `wElmsLabSceneID` == 0 | player auto-walked to (4,2); scene -> 1 (`CANT_LEAVE`) |
-| 11 | `ELMS_LAB` | ball object: (6,3) Cyndaquil / (7,3) Totodile / (8,3) Chikorita | face + A, answer **yes** to `yesorno` | `EVENT_GOT_A_POKEMON_FROM_ELM` clear | starter L5 w/ BERRY in party; `EVENT_GOT_<SP>_FROM_ELM`; ball disappears; auto-walk to (5,3); `ElmDirectionsScript` runs -> `EVENT_GOT_A_POKEMON_FROM_ELM`, `PHONE_ELM`, `ELMS_LAB` scene -> 5, `NEW_BARK_TOWN` scene -> 1 |
-| 12 | `ELMS_LAB` | (4,8) or (5,8) | walk onto on the way out | scene == 5 | `POTION` in bag; scene -> 2 (`NOOP`) |
-| 13 | `ELMS_LAB` | bg_event (2,1) | face UP + A -> yes (optional) | `EVENT_GOT_A_POKEMON_FROM_ELM` set | party healed (`special HealParty`) |
-| 14 | `ELMS_LAB` | warp 1 (4,11) or warp 2 (5,11) | walk onto | - | `NEW_BARK_TOWN` (6,3) |
-| 15 | `NEW_BARK_TOWN` | west edge past (1,8)/(1,9) | walk west | `NEW_BARK_TOWN` scene == 1 | crosses the `connection west, Route29` into `ROUTE_29` - section 01 |

-## 5. Port coverage
-
-| Beat | Port file | Status |
-|---|---|---|
-| Title -> NEW GAME -> Oak speech -> name pick -> naming screen -> bedroom | `src/ui/gen2/TitleState.lua`, `src/ui/gen2/MainMenu.lua`, `src/ui/gen2/OakSpeech.lua`, `src/ui/gen2/NamePick.lua`, `src/ui/gen2/NamingScreen.lua`; asserted end-to-end by `tests/drivers/gold_boot_smoke.lua` | implemented |
-| `InitClock` (the "what time is it?" / minute screens) | none - `src/ui/gen2/OakSpeech.lua:3` says outright "Gender select / InitClock are Crystal-later" | **missing** (bot step 2 has no screen to drive) |
-| `SPAWN_HOME` start at `PLAYERS_HOUSE_2F` (3,3) | `src/world/gen2/World.lua:228-232` (`START_MAP = "PLAYERS_HOUSE_2F"`, cites `data/maps/spawn_points.asm`) | implemented |
-| Map load, warps, collision, connections | `src/world/gen2/Map.lua`, `src/world/gen2/World.lua`; `tests/drivers/gold_walk_smoke.lua`, `tests/drivers/gold_warp_scene.lua` (asserts the New Bark door lands on `ELMS_LAB`) | implemented |
-| Scene scripts + coord events (the mechanism every gate in this section uses) | `src/world/gen2/World.lua:5011-5035` (`coordEvents` scan filtered by `self:scene()`, `sceneScripts` lookup), extracted by `src/import/RomExtractorGen2.lua:804-977` | implemented |
-| `MAPCALLBACK_NEWMAP` / `MAPCALLBACK_TILES`, `ToggleDecorationsVisibility`, `ToggleMaptileDecorations` | `src/script/gen2/Specials.lua:489-505`, `tests/drivers/gold_map_callbacks.lua`, `tests/gen2_map_callbacks_test.lua` | implemented |
-| `MeetMomScript` (emote, follow-free walk-in, `yesorno` under a prompt, mid-scene object swap) | driven by the VM; regression driver `tests/drivers/gold_mom_scene.lua` exists specifically for this scene; the Mom object-swap timing is commented at `src/world/gen2/World.lua:558-568,730` | implemented |
-| `special SetDayOfWeek` / `InitialSetDSTFlag` / `InitialClearDSTFlag` | `src/script/gen2/Specials.lua:836-860` | partial - the flags/RTC fields are written from the host clock, but no day-of-week picker UI is drawn, so the player never chooses |
-| Teacher west-exit gate | `tests/drivers/gold_teacher_scene.lua` (asserts `follow` drags the player back and she stands beside them) | implemented |
-| Rival push-out (`follow` + `jump_step` + `SFX_TACKLE`) | VM ops `follow`/`stopfollow` (`src/script/gen2/Opcodes.lua:117-118`), movement in `src/script/gen2/Movement.lua` | partial - opcodes present, no driver covering `NewBarkTownRivalScript` specifically |
-| Starter pick: `pokepic`, `cry`, `yesorno`, `disappear`, `givepoke SP, 5, BERRY` | `src/script/gen2/Opcodes.lua:91-92,51`; `src/script/gen2/Vm.lua:386-394` (`pokepic` -> `showPicFn`), `:439-445` (`givepoke` -> `givePokeFn` with species/level/held item) | partial - all opcodes implemented, but no driver or test in `tests/drivers/gold_*.lua` walks the Elm's Lab starter choice end to end |
-| `verbosegiveitem POTION` (aide) | `src/script/gen2/Vm.lua:490-510` (received text, SFX, "put in the ITEM POCKET") | implemented |
-| `addcellnum PHONE_MOM` / `PHONE_ELM`, Pokegear phone card | `src/script/gen2/Vm.lua:611`, `src/core/gen2/Phone.lua:137,146`, `src/ui/gen2/Pokegear.lua` | implemented |
-| `special HealParty` / `HealMachineAnim` (lab healing machine) | `src/script/gen2/Specials.lua:456` | implemented |
-| `special PlayersHousePC` + `warp NONE, 0, 0` | `src/script/gen2/Specials.lua:467-487`, `src/ui/gen2/PcMenu.lua` | implemented |
-| `special NameRival` (fires next section, from `CopScript`) | `src/script/gen2/Specials.lua:825-828` -> `World:nameRival` (`src/world/gen2/World.lua:4931`) | implemented |
-| Event-flag bitfield semantics (set flag = object hidden) | `src/world/gen2/Events.lua` (header comment cites `CheckObjectFlag` in `map_objects_2.asm`) | implemented |
-
-## 6. Unresolved / verify by hand
-
- **Everstone.** The FAQ lists "Everstone" under "Items found in New Bark Town".
-  There is no Everstone item ball, hidden item or bg_event on `MAP_NEW_BARK_TOWN`,
-  `MAP_ELMS_LAB`, `MAP_PLAYERS_HOUSE_1F` or `MAP_PLAYERS_HOUSE_2F`. The only New
-  Bark Town Everstone is `ElmGiveEverstoneScript` (`maps/ElmsLab.asm:338-347`),
-  which requires `EVENT_SHOWED_TOGEPI_TO_ELM` - a hatched Togepi shown to Elm,
-  many sections later. Treat the FAQ line as forward-looking, not as an item to
-  collect here.
- **"Pokegear" as an item.** The FAQ says "You get the Pokegear". In the asm it is
-  `setflag ENGINE_POKEGEAR` + `setflag ENGINE_PHONE_CARD`, with the item name
-  faked through `getstring STRING_BUFFER_4, PokegearName` ("#GEAR") into the
-  standard `ReceiveItemScript` text. Nothing enters the bag - a bot must not
-  check inventory for it.
- **"Professor Oak will ask you the time. First answer what hour it is and what
-  minute it is."** `InitClock` (`engine/rtc/timeset.asm`) is reached from
-  `OakSpeech` *before* any Oak text is printed (`farcall InitClock` is the first
-  instruction of `OakSpeech`), so the clock screen actually comes first and Oak's
-  greeting second. The FAQ's ordering is the reverse.
- **"even if you don't have the GBA on, the time will keep running"** - an RTC
-  hardware claim, nothing in the disassembly to cite; ignore.
- **East exit toward Route 27.** `data/maps/attributes.asm:121` gives New Bark Town
-  a `connection east, Route27, ROUTE_27, 0`, and unlike the west side there is
-  *no* coord event guarding it. Whether a bot can actually walk east before
-  getting Surf depends on the shoreline tiles in `maps/NewBarkTown.blk`, which I
-  did not decode. Verify by hand before relying on the west gate as the only exit
-  block.
- **Teacher gate coverage.** Only (1,8) and (1,9) carry coord events. If the map's
-  west connection strip is reachable at any other y, the gate has a hole. I read
-  the coord table but not the collision data, so this is unverified.
- **Rival battle.** The FAQ says only that he pushes you; confirmed - there is no
-  `loadtrainer`/`startbattle` in `NewBarkTownRivalScript`. The first rival battle
-  is not in this section.

-The two `SCENE_SPROUTTOWER3F_*` constants are generated inline by the

-
-**Scripts of interest**
-
- `VioletGymFalknerScript` (`56:412f`):
-  `faceplayer`, `opentext`, `checkevent EVENT_BEAT_FALKNER` /
-  `iftrue .FightDone`. First pass: `writetext FalknerIntroText`,
-  `winlosstext FalknerWinLossText, 0`, `loadtrainer FALKNER, FALKNER1`,
-  `startbattle`, `reloadmapafterbattle`, `setevent EVENT_BEAT_FALKNER`,
-  `writetext ReceivedZephyrBadgeText`, `playsound SFX_GET_BADGE`, `waitsfx`,
-  **`setflag ENGINE_ZEPHYRBADGE`**, `readvar VAR_BADGES`,
-  `scall VioletGymActivateRockets`.
-  Then `.FightDone` (`56:4159`): `checkevent EVENT_GOT_TM31_MUD_SLAP` /
-  `iftrue .SpeechAfterTM`; otherwise
-  `setevent EVENT_BEAT_BIRD_KEEPER_ROD`, `setevent EVENT_BEAT_BIRD_KEEPER_ABE`
-  (the two gym trainers are force-flagged so they never re-trigger),
-  `setmapscene ELMS_LAB, SCENE_ELMSLAB_NOOP`,
-  `specialphonecall SPECIALCALL_ASSISTANT`,
-  `writetext FalknerZephyrBadgeText`, `promptbutton`,
-  `verbosegiveitem TM_MUD_SLAP`, `iffalse .NoRoomForMudSlap`,
-  `setevent EVENT_GOT_TM31_MUD_SLAP`, `writetext FalknerTMMudSlapText`.
-  Unlike Sage Li, this one **does** check `verbosegiveitem`'s return, so a full
-  bag leaves `EVENT_GOT_TM31_MUD_SLAP` clear and the TM is offered again on the
-  next talk.
- `VioletGymActivateRockets` (`56:4185`): `ifequal 7, .RadioTowerRockets`,
-  `ifequal 6, .GoldenrodRockets` against the `VAR_BADGES` count. With one badge
-  this is a no-op; it exists so that a late Violet clear still arms the Rocket
-  arcs.
- `TrainerBirdKeeperRod` (`56:4194`), `TrainerBirdKeeperAbe` (`56:41a8`):
-  standard `trainer` headers + `endifjustbattled` after-battle text.
- `VioletGymGuideScript`: branches on `EVENT_BEAT_FALKNER`; pure text.

-## 3. Blockers and gates
-
-| Gate | Enforced by (file:label) | Requirement | Unlock condition |
-|---|---|---|---|
-| Sprout Tower 3F rival cutscene fires before you can reach Sage Li | `maps/SproutTower3F.asm` `coord_event 11, 9, SCENE_SPROUTTOWER3F_RIVAL_ENCOUNTER, SproutTower3FRivalScene` | Standing on (11,9) while `wSproutTower3FSceneID` == 0 | The scene's own `setscene SCENE_SPROUTTOWER3F_NOOP`. Not a hard block - the tile is on the only path north |
-| HM05 Flash | `maps/SproutTower3F.asm:SageLiScript` | Beat `SAGE, LI` (`loadtrainer` + `startbattle`) | `verbosegiveitem HM_FLASH` + `setevent EVENT_GOT_HM05_FLASH` |
-| Using Flash outside battle | `engine/events/overworld.asm` `FlashFunction.CheckUseFlash` (`03:48f1`): `ld de, ENGINE_ZEPHYRBADGE` / `farcall CheckBadge` / `jr c, .nozephyrbadge` | `ENGINE_ZEPHYRBADGE` set **and** `wTimeOfDayPalset == DARKNESS_PALSET` | Beat Falkner. Note the second half: even with the badge, Flash is refused on any map that is not a dark cave (`.notadarkcave` -> `FieldMoveFailed`) |
-| ZEPHYRBADGE attack boost / obedience | `engine/battle/core.asm:6566` (the `and` mask that starts `(1 << ZEPHYRBADGE)`) | badge bit | Beat Falkner |
-| Gym trainers Abe and Rod | `maps/VioletGym.asm` object events, `OBJECTTYPE_TRAINER` sight 3 on shared rows | eyesight only; they do **not** physically block the aisle | Beating them, or `EVENT_BEAT_BIRD_KEEPER_*` being force-set by `VioletGymFalknerScript.FightDone` |
-| Falkner re-battle | `maps/VioletGym.asm:VioletGymFalknerScript` `checkevent EVENT_BEAT_FALKNER` / `iftrue .FightDone` | none | one-shot |
-| Sage Li re-battle | `maps/SproutTower3F.asm:SageLiScript` `checkevent EVENT_GOT_HM05_FLASH` / `iftrue .GotFlash` | none | one-shot, keyed on the HM flag rather than on `EVENT_BEAT_SAGE_LI` |
-| Sprout Tower is a `DUNGEON` | `data/maps/maps.asm:79-81` | - | `ESCAPE_ROPE` and Dig work here, which is what the walkthrough's "you may use that to get out of the tower" relies on |
-
-Nothing in this section is gated on a field move, a key item, or an NPC standing
-on a tile. The only hard requirement is winning battles.

-## 5. Port coverage
-
-| Beat | Port file | Status |
-|---|---|---|
-| Map load, block grid, warps for all six maps (data-driven from the ROM) | `src/world/gen2/Map.lua`, `src/import/RomExtractorGen2.lua` (`readMapGroupEntry`, `mapNameByIds`) | implemented - ids are the same `MAP_*` names, see `tools/rom_manifest_gold.json` -> `constants.mapGroups` |
-| `MAPCALLBACK_NEWMAP` -> `setflag ENGINE_FLYPOINT_VIOLET` | `src/world/gen2/World.lua` (callback dispatch), driver `tests/drivers/gold_map_callbacks.lua` | implemented |
-| Fly point 66 = Violet | `src/world/gen2/FieldMoves.lua:346` (`{ landmark = "LANDMARK_VIOLET_CITY", spawn = "SPAWN_VIOLET", flag = 66 }`) | implemented |
-| Script VM for every `maps/*.asm` script in this section | `src/script/gen2/Vm.lua`, `src/script/gen2/Opcodes.lua` | implemented - scripts are disassembled from the ROM, not hand-ported, so `SageLiScript` / `VioletGymFalknerScript` run as-is |
-| `coord_event` + scene ids (the 3F rival trip-wire) | `src/world/gen2/World.lua:5013` (coord event scan), `:1183` / `:5026` (scene scripts) | implemented |
-| Cutscene opcodes used by `SproutTower3FRivalScene` (`showemote`, `earthquake`, `applymovement`, `turnobject`, `disappear`, `setscene`, `playmusic`) | `src/script/gen2/Opcodes.lua:122/125`, `src/world/gen2/World.lua:1006/1528/647`, `src/script/gen2/Movement.lua` | implemented |
-| `special FadeOutMusic` / `FadeOutToBlack` / `ReloadSpritesNoPalettes` / `FadeInFromBlack` / `RestartMapMusic` | `src/script/gen2/Specials.lua` | implemented |
-| Object masking by event flag (rival, item balls) | `src/world/gen2/Events.lua` (`objectVisible`), documented against `CheckObjectFlag` | implemented |
-| Trainer objects: eyesight, approach walk, seen text, battle, beat flag | `src/world/gen2/Trainers.lua`, `src/world/gen2/World.lua:5205-5253`, driver `tests/drivers/gold_trainer_smoke.lua` | implemented |
-| `loadtrainer` / `startbattle` for Sage Li and Falkner | `src/script/gen2/Vm.lua`, `src/battle/gen2/Battle.lua` | implemented |
-| Gym leader battle music | `src/battle/gen2/BattleMusic.lua:24` (`FALKNER = true`) | implemented |
-| Prize money (Falkner 900 = 25 x 9 x 4) | `src/battle/gen2/Prize.lua`, `tests/gen2_prize_test.lua` | implemented |
-| `setflag ENGINE_ZEPHYRBADGE` (id 26) and `readvar VAR_BADGES` | `src/script/gen2/Vm.lua:670`, `src/world/gen2/World.lua:117/1240`, `tests/gen2_world_test.lua:1783` | implemented |
-| Flash badge gate (`FlashFunction.CheckUseFlash`) | `src/world/gen2/FieldMoves.lua:105` (`FLASH = "ZEPHYR"`), `tests/gen2_world_test.lua:755-781` | implemented, including the "refused before the darkness check" ordering |
-| `verbosegiveitem` (HM05, TM31) incl. the `iffalse` no-room arm | `src/script/gen2/Vm.lua:490-500` | implemented |
-| Hidden item at Violet City (37,14) | `src/world/gen2/HiddenItems.lua`, `src/world/gen2/World.lua:5285` | implemented |
-| Berry tree `fruittree FRUITTREE_VIOLET_CITY` | `src/script/gen2/CallAsm.lua:75-77`, `src/core/gen2/Apricorns.lua:363` | implemented |
-| `specialphonecall SPECIALCALL_ASSISTANT` | `src/script/gen2/Opcodes.lua:161`, `src/core/gen2/Phone.lua:390` | implemented |
-| `giveegg TOGEPI` (Elm's aide, next section's payoff) | `src/script/gen2/Vm.lua:453`, driver `tests/drivers/gold_egg_hatch.lua` | implemented |
-| Earl's `follow` / `stopfollow` escort | `src/script/gen2/Vm.lua:982` | implemented |
-| **Poke Ball item pickup (`OBJECTTYPE_ITEMBALL`)** - Parlyz Heal, X Defend, Potion, Escape Rope, PP Up, Rare Candy | `src/import/RomExtractorGen2.lua:2969` writes `obj.itemball`; **nothing in `src/` reads it**, and `World:interact()` (`src/world/gen2/World.lua:5257`) has no itemball branch (trainer / strength boulder / `scriptKey` / bg sign / hidden item only). `src/script/gen2/CallAsm.lua:550` stubs `TryReceiveItem` out on purpose | **missing** - the balls render and are masked correctly, but pressing A on one does nothing. Every item ball in this section is unobtainable in the port today |
-| Hand-ported per-map Lua for Sprout Tower / Violet Gym | none - by design | n/a (the port runs the ROM's own bytecode) |
-
-## 6. Unresolved / verify by hand
-
-1. **"X Accuracy" in the Sprout Tower item list.** The walkthrough's header
-   lists Escape Rope, HM05, Parlyz Heal, Potion, **X Accuracy**, and the prose
-   says "grab that X Defense above you". The asm has exactly one such ball,
-   `SproutTower2FXDefend` = `itemball X_DEFEND` at 2F (3,1). There is no
-   `X_ACCURACY` anywhere in `maps/SproutTower*.asm`. The header list is wrong;
-   the prose is right.
-
-2. **"Go up to the item to the right of the monk. In reality, it is a...
-   Level 3 Rattata"** and the follow-up "Go back to the Rattata you faced
-   before, and now it's an Escape Rope." Nothing in `maps/SproutTower3F.asm`
-   supports this. The object at (14,1) is a plain
-   `object_event ... OBJECTTYPE_ITEMBALL, 0, SproutTower3FEscapeRope,
-   EVENT_SPROUT_TOWER_3F_ESCAPE_ROPE` whose script label is a bare
-   `itemball ESCAPE_ROPE`. There is no `wildbattle`, no `loadwildmon`, no
-   second object at that cell, and no branch on `EVENT_GOT_HM05_FLASH` anywhere
-   near it. This looks like the walkthrough importing the Gen 1 Rocket Hideout
-   Voltorb trick. **Treat the ball at (14,1) as an ordinary Escape Rope.**
-
-3. **"Pokemon found in Sprout Tower: Rattata, Bellsprout, Gastly."**
-   `data/wild/johto_grass.asm` gives Rattata (morn/day) and Gastly + Rattata
-   (nite) for `SPROUT_TOWER_2F` and `SPROUT_TOWER_3F`, and **no table at all**
-   for `SPROUT_TOWER_1F`. Bellsprout is not a Sprout Tower wild encounter; the
-   Bellsprouts are the sages' party members.
-
-4. **Sage Li's party order.** The walkthrough lists L7 Bellsprout, L10 Hoothoot,
-   L7 Bellsprout. `data/trainers/parties.asm` `SageGroup` "LI" is
-   `db 7, BELLSPROUT / db 7, BELLSPROUT / db 10, HOOTHOOT` - the Hoothoot is
-   last, not second. The 320G figure the walkthrough quotes only works with the
-   asm order, since `ComputeTrainerReward` uses the level of the **last** party
-   row (8 x 10 x 4 = 320).
-
-5. **Walkthrough trainer order in the gym.** The text says "Head up to fight
-   your trainer battles first. Bird Keeper Abe ... Head up the path to the
-   second trainer. Bird Keeper Rod." Geometrically that is correct (Abe at
-   y=10 is south of Rod at y=6), but be aware the *object const* order in the
-   file is Rod first (`VIOLETGYM_YOUNGSTER1`), Abe second
-   (`VIOLETGYM_YOUNGSTER2`), which is the opposite of the walk order. Do not
-   index trainers by object const when following the prose.
-
-6. **"You'll need the 1st badge to use it [Flash]".** True but incomplete:
-   `FlashFunction.CheckUseFlash` (`engine/events/overworld.asm`, `03:48f1`)
-   requires `ENGINE_ZEPHYRBADGE` **and** `wTimeOfDayPalset == DARKNESS_PALSET`.
-   With the badge, on any non-dark map, the move still fails through
-   `.notadarkcave` -> `FieldMoveFailed`. A bot should not treat "have badge" as
-   "Flash will work here".
-
-7. **EXP values.** The walkthrough quotes per-Pokemon EXP figures (54, 108, 126,
-   217, ...). Those are computed from base experience and level at runtime
-   (`engine/battle/experience.asm` / `data/pokemon/base_stats/`), not stored
-   anywhere as a per-trainer constant, so they were not verified against a
-   single asm line here. The **money** figures were: all seven quoted values
-   match `base reward x last party level x 4`.
-
-8. **"you should be around an hour into the game now"** and the video link -
-   prose, nothing to resolve.

-Maps covered: `MAP_AZALEA_TOWN`, `MAP_KURTS_HOUSE`, `MAP_AZALEA_POKECENTER_1F`,
-`MAP_SLOWPOKE_WELL_B1F`, `MAP_SLOWPOKE_WELL_B2F` (off-route, Surf-only),
-`MAP_AZALEA_GYM`. `MAP_AZALEA_MART` is referenced for its stock only
-(`data/items/marts.asm` `MartAzalea`); its map file was not transcribed.
-Badges / key milestones in this section: **HIVEBADGE** (`ENGINE_HIVEBADGE`),
-`EVENT_CLEARED_SLOWPOKE_WELL`, `EVENT_BEAT_BUGSY`, `TM_FURY_CUTTER` (TM49),
-`LURE_BALL`, `SUPER_POTION`, `WHT_APRICORN`, hidden `FULL_HEAL`. Clearing the
-well is what unlocks the Gym door and arms the Azalea rival battle for the next
-section.
-
-Coordinate convention throughout: the raw asm x/y from
-`warp_event` / `coord_event` / `bg_event` / `object_event`, i.e. walk cells
-(two 8x8 tiles per side, two cells per map block). `macros/scripts/maps.asm`
-adds the +4 border internally; the numbers below are the pre-border values as
-written in the map file.

-
-| # | Map constant | asm file | Enter via | Leaves via | Why (walkthrough beat) |
-|---|---|---|---|---|---|
-| 1 | `MAP_AZALEA_TOWN` | `maps/AzaleaTown.asm` | west edge of Route 33 (`connection east, Route33, ROUTE_33, 0` in `data/maps/attributes.asm`) | warp 4, `warp_event 9, 5, KURTS_HOUSE, 1` | Rocket guard is standing on the well; head west then north to Kurt's house |
-| 2 | `MAP_KURTS_HOUSE` | `maps/KurtsHouse.asm` | warp 1 (`3, 7`) | warps 1/2 (`3, 7` / `4, 7`) back to `AZALEA_TOWN` warp 4 | `Kurt1` first-visit arm: Kurt storms off to the well and sets `EVENT_AZALEA_TOWN_SLOWPOKETAIL_ROCKET`, which hides the guard |
-| 3 | `MAP_AZALEA_POKECENTER_1F` | `maps/AzaleaPokecenter1F.asm` | `AZALEA_TOWN` warp 1 (`15, 9`) | warps 1/2 (`3, 7` / `4, 7`) | "heal at the Pokemon Center" |
-| 4 | `MAP_AZALEA_TOWN` | `maps/AzaleaTown.asm` | Pokecenter warp | warp 6, `warp_event 31, 7, SLOWPOKE_WELL_B1F, 1` | walk east to the now-unguarded well |
-| 5 | `MAP_SLOWPOKE_WELL_B1F` | `maps/SlowpokeWellB1F.asm` | warp 1 (`17, 15`) | **scripted** `warp KURTS_HOUSE, 3, 3` at the end of `TrainerGruntM1.Script` | four Rocket grunts, Super Potion, tailless Slowpoke |
-| 6 | `MAP_KURTS_HOUSE` | `maps/KurtsHouse.asm` | script warp to `3, 3` | warps 1/2 | `Kurt1.ClearedSlowpokeWell` -> free `LURE_BALL` |
-| 7 | `MAP_AZALEA_TOWN` | `maps/AzaleaTown.asm` | Kurt's House warp | fruit tree object at `8, 2`, then warp 1 (Pokecenter) | `WHT_APRICORN` from `WhiteApricornTree` / `FRUITTREE_AZALEA_TOWN`, then heal |
-| 8 | `MAP_AZALEA_GYM` | `maps/AzaleaGym.asm` | `AZALEA_TOWN` warp 5, `warp_event 10, 15, AZALEA_GYM, 1` | warps 1/2 (`4, 15` / `5, 15`) | five gym trainers + Bugsy -> HIVEBADGE + TM49 |
-
-Off-route in this section: `MAP_SLOWPOKE_WELL_B2F` (`maps/SlowpokeWellB2F.asm`)
-hangs off `SLOWPOKE_WELL_B1F` warp 2 at `7, 11`, but the only land approach to
-that ladder is across water (see the derived grid under B1F) - it is a Surf
-return trip, not part of this visit, and holds the King's Rock and TM Rain Dance.
-
-Spills into the next section: `AzaleaTown_MapEvents` has
-`coord_event 5, 10` / `coord_event 5, 11` for `SCENE_AZALEATOWN_RIVAL_BATTLE`.
-`TrainerGruntM1.Script` arms that scene with
-`setmapscene AZALEA_TOWN, SCENE_AZALEATOWN_RIVAL_BATTLE`, so the rival ambush
-fires the first time you walk west toward the Ilex Forest gate. That battle and
-Ilex Forest belong to section 05.

-`SPRITE_AZALEA_ROCKET` (`constants/sprite_constants.asm:156`, id `$f6`) is a

-in `maps/SlowpokeWellB1F.asm` re-points it with
-`variablesprite SPRITE_AZALEA_ROCKET, SPRITE_RIVAL`, which is why const 11 draws
-as the rival even though the row names the Rocket slot.

-Two chokepoints matter: `31, 9` is the only walkable cell that reaches `31, 8`
-and then the well ladder at `31, 7`, and `10, 16` is the only walkable cell
-adjacent to the Gym door at `10, 15` (`9, 15`, `11, 15` and `10, 14` are all
-wall). The two Rocket objects sit exactly on those cells.
-
-**Scripts of interest**
-
- `AzaleaTownFlypointCallback` - `MAPCALLBACK_NEWMAP`; `setflag ENGINE_FLYPOINT_AZALEA`,
-  `endcallback`. Entering the map once is enough to register the fly point.
- `AzaleaTownRocket1Script` / `AzaleaTownRocket2Script` -
-  `jumptextfaceplayer AzaleaTownRocket1Text` / `...Rocket2Text`. Pure flavour;
-  neither one gates anything by script. They block by standing on tiles.
- `AzaleaTownGrampsScript` - `checkevent EVENT_CLEARED_SLOWPOKE_WELL` /
-  `iftrue .ClearedWell`, then one of `AzaleaTownGrampsTextBefore` /
-  `AzaleaTownGrampsTextAfter`. Cheap read-only probe of well state.
- `WhiteApricornTree` - `fruittree FRUITTREE_AZALEA_TOWN`.
-  `constants/script_constants.asm:226` gives `FRUITTREE_AZALEA_TOWN ; 14` (hex),
-  and `data/items/fruit_trees.asm:23` is `db WHT_APRICORN ; AZALEA_TOWN`.
-  Once-per-day, tracked by the fruit-tree daily bit, not by an `EVENT_*`.
- `AzaleaTownHiddenFullHeal` - `hiddenitem FULL_HEAL, EVENT_AZALEA_TOWN_HIDDEN_FULL_HEAL`;
-  reached by facing the wall cell `31, 6` from `31, 7`/`31, 5` neighbours.
- `AzaleaTownRivalBattleScene1` / `...Scene2` / `AzaleaTownRivalBattleScript` -
-  next section. For completeness they `setevent EVENT_RIVAL_AZALEA_TOWN`,
-  branch on `EVENT_GOT_TOTODILE_FROM_ELM` / `EVENT_GOT_CHIKORITA_FROM_ELM`,
-  `loadtrainer RIVAL1, RIVAL1_2_TOTODILE|RIVAL1_2_CHIKORITA|RIVAL1_2_CYNDAQUIL`,

-
-Object visibility semantics, since everything above depends on it:
-`engine/overworld/scripting.asm:879` `Script_appear` calls
-`ApplyEventActionAppearDisappear` with `b = 0 ; clear`, and `:887`
-`Script_disappear` with `b = 1 ; set`. **An object's `EVENT_*` flag SET means the
-object is hidden.**

-Route through the well, matching the walkthrough beat for beat:
-`17, 15` (entry ladder) -> Kurt at `16, 14` -> north up the `14-15` column to
-`14, 8`/`15, 8` where `TrainerGruntM29` sees you -> continue north to the top
-room `9..14, 2..4`, where `TrainerGruntF1` at `13, 2` faces down with sight 2 ->
-Super Potion ball at `10, 3` -> back east/down through the gap at `11, 5` into
-the long row-6 corridor -> west to `TrainerGruntM2` at `5, 6` (faces right,
-sight 2) -> Slowpoke with mail at `7, 4`, tailless Slowpoke at `6, 2` ->
-`TrainerGruntM1` at `5, 2` (faces down, sight 1).
-
-The B2F ladder at `7, 11` sits in a chamber walled off along row 7 and reachable
-only from `7, 13`, whose only non-wall neighbour outside the chamber is the water
-at `7, 14`. **B2F is Surf-only**; the water is also the only route down from the
-land at `2, 11`.
-
-**Scripts of interest**
-
- `SlowpokeWellB1FKurtScript` - `jumptextfaceplayer SlowpokeWellB1FKurtText`.
-  Flavour only; Kurt does not gate anything here.
- `TrainerGruntM29` - `trainer GRUNTM, GRUNTM_29, EVENT_BEAT_ROCKET_GRUNTM_29, GruntM29SeenText, GruntM29BeatenText, 0, .Script`;
-  `.Script` is `endifjustbattled` + `GruntM29AfterBattleText`. Talking again is
-  the "they're chopping off Slowpoke tails" line the walkthrough mentions.
- `TrainerGruntF1` - `trainer GRUNTF, GRUNTF_1, EVENT_BEAT_ROCKET_GRUNTF_1, ...`,
-  same `endifjustbattled` shape.
- `TrainerGruntM2` - `trainer GRUNTM, GRUNTM_2, EVENT_BEAT_ROCKET_GRUNTM_2, ...`,
-  same shape.
- `TrainerGruntM1` - **the section's payload.**
-  `trainer GRUNTM, GRUNTM_1, EVENT_BEAT_ROCKET_GRUNTM_1, GruntM1SeenText, GruntM1BeatenText, 0, .Script`.
-  `.Script` has no `endifjustbattled`, so it runs immediately after the win:
-  `writetext TrainerGruntM1WhenTalkText`, `special FadeOutToBlack`,
-  `special ReloadSpritesNoPalettes`,
-  `disappear` on consts 2/3/4/5 (all four share `EVENT_SLOWPOKE_WELL_ROCKETS`,
-  so this is the flag that clears the Gym door in town), `pause 15`,
-  `special FadeInFromBlack`, `disappear SLOWPOKEWELLB1F_KURT`,
-  `moveobject SLOWPOKEWELLB1F_KURT, 11, 6`, `appear SLOWPOKEWELLB1F_KURT`,
-  `applymovement SLOWPOKEWELLB1F_KURT, KurtSlowpokeWellVictoryMovementData`
-  (4x `step LEFT`, `step UP`, 3x `step_sleep 8`, `step LEFT`, 2x `step UP`,
-  3x `step_sleep 8`, `turn_head LEFT`), `turnobject PLAYER, RIGHT`,
-  `writetext KurtLeaveSlowpokeWellText`, then the flag block:
-  ```
-  setevent   EVENT_CLEARED_SLOWPOKE_WELL

-  clearevent EVENT_AZALEA_TOWN_SLOWPOKES
-  clearevent EVENT_KURTS_HOUSE_SLOWPOKE
-  clearevent EVENT_KURTS_HOUSE_KURT_1
-  ```
-  then `special FadeOutToWhite`, `special HealParty`, `pause 15`,
-  `warp KURTS_HOUSE, 3, 3`, `end`. Note the free party heal, and note that the
-  Ilex Forest Farfetch'd quest is armed here, not in Ilex Forest.
- `SlowpokeWellB1FSlowpokeWithMailScript` - `faceplayer`, `cry SLOWPOKE`,
-  `SlowpokeWellB1FSlowpokeWithMailText`, `yesorno` / `iftrue .ReadMail` ->
-  `SlowpokeWellB1FSlowpokeMailText`. No flag, no item, purely optional.
- `SlowpokeWellB1FSuperPotion` - `itemball SUPER_POTION`, guarded by
-  `EVENT_SLOWPOKE_WELL_B1F_SUPER_POTION`.
- `SlowpokeWellB1FBoulder` - `jumpstd StrengthBoulderScript`; needs Strength,
-  which is not obtainable in this section.

-It is a spiral. Entry `4, 15` / `5, 15` -> `4, 14`..`7, 14` -> the two
-entry stalks at columns 4-5 and 7 -> the row 10/11 ring -> up either side
-column (0-1 or 8-9) -> row 2/3 -> in at `4, 4` / `5, 4` -> `4, 5`..`6, 5` ->
-`3, 6` -> `3, 7` -> Bugsy at `5, 7`.
-
-Derived from the grid plus the sight fields: only the **twins** sit on the
-straight-line path (`4, 11` and `5, 11` are their sight cells), and even they
-are dodgeable by taking the column-7 stalk from `7, 14` up to `7, 11`. Josh's
-sight covers `0, 3`-`0, 5` so the left column is his; Al's covers `8, 9`-`8, 11`
-so the column-8 approach is his; column 9 is clear all the way from row 11 to
-row 3. Benny spins (`SPINRANDOM_FAST`, sight 2) at `5, 3`, so crossing row 2/3
-near column 5 is a coin flip rather than a guarantee.

-  `ifequal 6, .GoldenrodRockets`, `end`. `VAR_BADGES`
-  (`constants/script_constants.asm:55`, id 7) is the badge count, which is 2
-  right after HIVEBADGE, so **this scall is a no-op at Bugsy**; it is the shared
-  gym-clear hook that only fires at the 6th and 7th badge.
- `TrainerTwinsAmyandmay1` / `TrainerTwinsAmyandmay2` - both use
-  `EVENT_BEAT_TWINS_AMY_AND_MAY`, so you fight **one** twin, whichever spots you
-  first, and the other drops to her after-battle line.
- `TrainerBugCatcherBenny` / `...Al` / `...Josh` - plain
-  `trainer BUG_CATCHER, <id>, EVENT_BEAT_BUG_CATCHER_<id>, ...` with
-  `endifjustbattled` after-scripts.
- `AzaleaGymGuideScript` - `checkevent EVENT_BEAT_BUGSY`; the pre-battle text is
-  the "bug Pokemon don't like fire, flying-type moves are super-effective" hint.

-## 3. Blockers and gates
-
-| Gate | Enforced by (file:label) | Requirement | Unlock condition |
-|---|---|---|---|
-| Rocket standing on the Slowpoke Well approach | `maps/AzaleaTown.asm` object const 2 at `31, 9`, flag `EVENT_AZALEA_TOWN_SLOWPOKETAIL_ROCKET`. `31, 9` is the only walkable neighbour of `31, 8`, which is the only walkable neighbour of the ladder at `31, 7` (derived from `maps/AzaleaTown.blk` + `data/tilesets/johto_modern_collision.asm`) | talk to Kurt once | `Kurt1` first-visit arm runs `setevent EVENT_AZALEA_TOWN_SLOWPOKETAIL_ROCKET`, which hides him (`Script_disappear` semantics, `engine/overworld/scripting.asm:887`) |
-| Rocket standing on the Azalea Gym door | `maps/AzaleaTown.asm` object const 12 at `10, 16`, flag `EVENT_SLOWPOKE_WELL_ROCKETS`. `10, 16` is the only walkable neighbour of the gym warp at `10, 15` | clear Slowpoke Well | the four `disappear SLOWPOKEWELLB1F_ROCKET*` calls in `maps/SlowpokeWellB1F.asm` `TrainerGruntM1.Script` set that shared flag |
-| Slowpoke Well B2F (King's Rock, TM Rain Dance) | `maps/SlowpokeWellB1F.asm` warp 2 at `7, 11`; the chamber's only outside neighbour is water at `7, 14` (derived from `maps/SlowpokeWellB1F.blk` + `data/tilesets/cave_collision.asm` + `data/collision/collision_permissions.asm`) | Surf (`ENGINE_FOGBADGE` + HM03) | out of section - Fog Badge is Morty |
-| Boulder at Slowpoke Well `3, 2` | `SlowpokeWellB1FBoulder` -> `jumpstd StrengthBoulderScript` | Strength | out of section; nothing behind it is required |
-| Field Cut (leaving Azalea west for Ilex Forest) | `engine/events/overworld.asm` `CutFunction.CheckAble` (`ld de, ENGINE_HIVEBADGE` / `call CheckBadge` / `jr c, .nohivebadge`, sym `03:47e1`) and `TryCutOW` (`CheckPartyMove` with `CUT`, then `ld de, ENGINE_HIVEBADGE` / `CheckEngineFlag`, sym `03:5193`) | HIVEBADGE **and** a party member that knows CUT | HIVEBADGE from `AzaleaGymBugsyScript`; HM01 itself comes from the Charcoal Kiln / Ilex Forest chain in section 05 |
-| Pokemon obedience above L30 | `engine/battle/core.asm:6566` masks `(1 << ZEPHYRBADGE) | (1 << HIVEBADGE) | ...` | HIVEBADGE | same |
-| Bugsy himself | `AzaleaGymBugsyScript` has no `checkevent` guard before the battle | nothing - the five gym trainers are optional | `.FightDone` force-sets all four of their beat events afterwards |
-
-## 4. Bot checklist
-
-Coordinates are `x, y` as written in the asm. "warp N" means the Nth
-`warp_event` row of the source map.
-
-1. `MAP_AZALEA_TOWN`, walk in from the Route 33 east connection. Post: engine
-   flag `ENGINE_FLYPOINT_AZALEA` set by `AzaleaTownFlypointCallback`
-   (`MAPCALLBACK_NEWMAP`). No input needed.
-2. `MAP_AZALEA_TOWN`, walk to `9, 5` and step on it -> warp 4 ->
-   `MAP_KURTS_HOUSE` `3, 7`. Pre: none.
-3. `MAP_KURTS_HOUSE`, walk to `3, 3`, face UP, press A on object const 2
-   (`KURTSHOUSE_KURT1`, `3, 2`). Pre: `EVENT_CLEARED_SLOWPOKE_WELL` clear and
-   `EVENT_KURT_GAVE_YOU_LURE_BALL` clear. Post:
-   `EVENT_AZALEA_TOWN_SLOWPOKETAIL_ROCKET` set, `EVENT_KURTS_HOUSE_KURT_1` set
-   (Kurt walks out). If the player is facing UP when the script starts, Kurt
-   takes the `.RunAround` movement instead - same result, one extra step.
-4. `MAP_KURTS_HOUSE`, step on `3, 7` or `4, 7` -> `MAP_AZALEA_TOWN` warp 4 (`9, 5`).
-5. Optional heal: `MAP_AZALEA_TOWN` `15, 9` -> `MAP_AZALEA_POKECENTER_1F`;
-   talk to object const 2 at `3, 1` (`jumpstd PokecenterNurseScript`); leave via
-   `3, 7`.
-6. `MAP_AZALEA_TOWN`, walk east along row 10 to `31, 10`, north to `31, 9`
-   (now empty), `31, 8`, then step on `31, 7` -> warp 6 -> `MAP_SLOWPOKE_WELL_B1F`
-   `17, 15`. Optional: from `31, 7` face UP and press A for the hidden
-   `FULL_HEAL` at `31, 6` (post: `EVENT_AZALEA_TOWN_HIDDEN_FULL_HEAL`).
-7. `MAP_SLOWPOKE_WELL_B1F`, optional A on const 8 (`16, 14`, Kurt).
-8. Walk north along column 15 to `15, 8`. Trigger: const 2 `TrainerGruntM29`
-   (sight 1, faces right). Battle `GRUNTM` / `GRUNTM_29` (L9 Rattata x2).
-   Post: `EVENT_BEAT_ROCKET_GRUNTM_29`. Optional A again for the after-battle text.
-9. Continue north column 14 to `14, 4`, then west into the top room. Trigger:
-   const 5 `TrainerGruntF1` at `13, 2` (sight 2, faces down) from `13, 3` or
-   `13, 4`. Battle `GRUNTF` / `GRUNTF_1` (L9 Zubat, L11 Ekans). Post:
-   `EVENT_BEAT_ROCKET_GRUNTF_1`.
-10. Walk to `11, 3` -> `10, 3`, press A on const 10 -> `SUPER_POTION`. Post:
-    `EVENT_SLOWPOKE_WELL_B1F_SUPER_POTION`.
-11. Go to `11, 4` -> `11, 5` -> `11, 6`, then west along row 6. Trigger: const 4
-    `TrainerGruntM2` at `5, 6` (sight 2, faces right) from `7, 6` or `6, 6`.
-    Battle `GRUNTM` / `GRUNTM_2` (L7 Rattata, L9 Zubat, L9 Zubat). Post:
-    `EVENT_BEAT_ROCKET_GRUNTM_2`.
-12. Optional: `7, 5` face UP, A on const 6 at `7, 4` (Slowpoke with mail,
-    `yesorno` -> read). No flag.
-13. Walk to `5, 3`. Trigger: const 3 `TrainerGruntM1` at `5, 2` (sight 1, faces
-    down). Battle `GRUNTM` / `GRUNTM_1` (L14 Koffing). Post:
-    `EVENT_BEAT_ROCKET_GRUNTM_1`, then `.Script` runs with no `endifjustbattled`,
-    so the whole cutscene plays automatically and ends with
-    `special HealParty` + `warp KURTS_HOUSE, 3, 3`. Post-flags to assert:
-    `EVENT_CLEARED_SLOWPOKE_WELL`, `EVENT_SLOWPOKE_WELL_ROCKETS`,
-    `EVENT_SLOWPOKE_WELL_SLOWPOKES`, `EVENT_SLOWPOKE_WELL_KURT`,
-    `EVENT_CHARCOAL_KILN_FARFETCH_D`, `EVENT_CHARCOAL_KILN_APPRENTICE`;
-    cleared: `EVENT_AZALEA_TOWN_SLOWPOKES`, `EVENT_KURTS_HOUSE_SLOWPOKE`,
-    `EVENT_KURTS_HOUSE_KURT_1`, `EVENT_ILEX_FOREST_APPRENTICE`,
-    `EVENT_ILEX_FOREST_FARFETCHD_1`; scene: `AZALEA_TOWN` -> `SCENE_AZALEATOWN_RIVAL_BATTLE`.
-14. `MAP_KURTS_HOUSE` at `3, 3`, face UP, A on const 2. Pre:
-    `EVENT_CLEARED_SLOWPOKE_WELL` set, `EVENT_KURT_GAVE_YOU_LURE_BALL` clear.
-    Post: `LURE_BALL` in bag, `EVENT_KURT_GAVE_YOU_LURE_BALL` set. The script
-    then falls straight into the apricorn prompt - answer no unless you want to
-    hand over the White Apricorn you have not picked yet.
-15. Leave via `3, 7`; in `MAP_AZALEA_TOWN` walk to `8, 3`, face UP, A on const 10
-    at `8, 2` -> `WHT_APRICORN` (daily). Optional: return to Kurt and give it
-    (`special SelectApricornForKurt`, post: `EVENT_GAVE_KURT_WHT_APRICORN` +
-    `ENGINE_KURT_MAKING_BALLS`), then come back a real in-game day later for
-    `FAST_BALL`.
-16. Optional heal at the Pokecenter (`15, 9`).
-17. `MAP_AZALEA_TOWN`, walk to `10, 17` -> `10, 16` (now empty) -> step on
-    `10, 15` -> warp 5 -> `MAP_AZALEA_GYM` `4, 15`.
-18. `MAP_AZALEA_GYM`: optional A on const 8 at `7, 13` for the type hint.
-    Walk `4, 14` -> `4, 13` -> `4, 12` -> `4, 11`. Trigger: const 6
-    `TrainerTwinsAmyandmay1` at `4, 10` (sight 1). Battle `TWINS` / `AMYANDMAY1`
-    (L10 Spinarak, L10 Ledyba). Post: `EVENT_BEAT_TWINS_AMY_AND_MAY`, which also
-    retires const 7.
-19. West along row 11 to `0, 11`, north up column 0 to `0, 5`. Trigger: const 5
-    `TrainerBugCatcherJosh` at `0, 2` (sight 3, faces down). Battle
-    `BUG_CATCHER` / `JOSH` (L13 Paras). Post: `EVENT_BEAT_BUG_CATCHER_JOSH`.
-20. North to `0, 3`, east along row 3 toward `4, 3`. Trigger: const 3
-    `TrainerBugCatcherBenny` at `5, 3` (sight 2, spins). Battle
-    `BUG_CATCHER` / `BENNY` (L7 Weedle, L9 Kakuna, L12 Beedrill). Post:
-    `EVENT_BEAT_BUG_CATCHER_BENNY`.
-21. East along row 2/3 to column 8-9, south to `8, 11`. Trigger: const 4
-    `TrainerBugCatcherAl` at `8, 8` (sight 3, faces down). Battle
-    `BUG_CATCHER` / `AL` (L12 Caterpie, L12 Weedle). Post:
-    `EVENT_BEAT_BUG_CATCHER_AL`.
-22. Route into the middle: `4, 3` or `5, 3` row -> `4, 4` -> `4, 5` -> `3, 5` ->
-    `3, 6` -> `3, 7` -> `4, 7`, face RIGHT, A on const 2 at `5, 7`. Pre:
-    `EVENT_BEAT_BUGSY` clear. Battle `BUGSY` / `BUGSY1` (L14 Metapod, L14 Kakuna,
-    L16 Scyther). Post: `EVENT_BEAT_BUGSY`, `ENGINE_HIVEBADGE`, then the same
-    conversation continues and yields `TM_FURY_CUTTER` +
-    `EVENT_GOT_TM49_FURY_CUTTER` and force-sets the four gym-trainer events.
-    A bot that wants the badge fast can skip steps 19-21 entirely.
-23. Leave via `4, 15` / `5, 15`. Next section starts when you walk west and hit
-    `coord_event 5, 10` / `5, 11`.

-## 5. Port coverage
-
-| Beat | Port file | Status |
-|---|---|---|
-| Map data for all six maps (blocks, connections, warps, coord/bg/object events, `scriptKey`) | `src/import/RomExtractorGen2.lua` (`self:write("maps", out)`, line 987), consumed by `src/world/gen2/Map.lua` | implemented - `docs/gold-phase1.md` states all 368 maps extract |
-| Collision / walkability (`COLL_*` quads, block -> cell) | `src/world/gen2/Map.lua` `Map:cellCollision`, `src/world/gen2/Permissions.lua` | implemented (quad order `ly*2 + lx` matches `gfx/tilesets.asm` `tilecoll`) |
-| Warps between these maps | `src/world/gen2/World.lua` + `Map:warpAt`; driver `tests/drivers/gold_warp_scene.lua` | implemented |
-| Map callbacks (`MAPCALLBACK_NEWMAP` flypoint, `MAPCALLBACK_OBJECTS` Kurt swap) | `src/world/gen2/World.lua`, driver `tests/drivers/gold_map_callbacks.lua` | implemented |
-| Script VM opcodes used here (`checkevent`/`setevent`/`clearevent`, `checkflag`/`setflag`, `readvar`, `scall`, `jumpstd`, `special`, `warp`, `setscene`/`setmapscene`, `loadtrainer`/`startbattle`/`winlosstext`/`endifjustbattled`, `applymovement`, `moveobject`, `showemote`, `variablesprite`, `verbosegiveitem`, `yesorno`, `checkitem`, `promptbutton`, `fruittree`) | `src/script/gen2/Opcodes.lua`, `src/script/gen2/Vm.lua` | implemented - every opcode in this section's scripts has a row and a VM arm |
-| Specials used here (`FadeOutToBlack`, `FadeInFromBlack`, `FadeOutToWhite`, `ReloadSpritesNoPalettes`, `HealParty`, `SelectApricornForKurt`, `FadeOutMusic`/`RestartMapMusic`) | `src/script/gen2/Specials.lua` | implemented (spot-checked `FadeOutToBlack`, `ReloadSpritesNoPalettes`, `HealParty`, `SelectApricornForKurt`) |
-| Trainer sight lines / approach walk (the four grunts, the five gym trainers) | `src/world/gen2/Trainers.lua` (`Trainers.sees`, `Trainers.approach`), wired at `src/world/gen2/World.lua:5212-5264`; driver `tests/drivers/gold_trainer_smoke.lua` | implemented |
-| Trainer parties + class attributes | `src/import/RomExtractorGen2.lua` (trainers), `src/world/gen2/Trainers.lua`, `src/battle/gen2/Battle.lua` (`BUGSY` in the gym-leader set, line 85) | implemented |
-| Prize money (base x level x 4, Mom's split) | `src/battle/gen2/Prize.lua` | implemented, and it ports the `ld c, 4` loop and `.DoubleReward` faithfully |
-| Badge storage + `VAR_BADGES` count | `src/core/gen2/Save.lua` (`player.badges`, `player.kantoBadges`), `src/world/gen2/World.lua:1241-1244`, `World:engineFlags` (`:1304`) | implemented |
-| Cut gate on `ENGINE_HIVEBADGE` | `src/world/gen2/FieldMoves.lua` (`FieldMoves.BADGE.CUT = "HIVE"`, `cutFromMenu`, the overworld ask path) | implemented |
-| Fly point `ENGINE_FLYPOINT_AZALEA` | `src/world/gen2/FieldMoves.lua:347` (`LANDMARK_AZALEA_TOWN` / `SPAWN_AZALEA` / flag 67) | implemented |
-| Hidden item at `31, 6` (`BGEVENT_ITEM`) | `src/world/gen2/HiddenItems.lua` | implemented (module exists and the extractor carries `hiddenItem = { item, event }`); not exercised by any Azalea driver |
-| Kurt / apricorn conversation, `ENGINE_KURT_MAKING_BALLS` day wait, Lure Ball, Fast Ball | `src/core/gen2/Apricorns.lua` | implemented at the model level; the file is written against `maps/KurtsHouse.asm` directly and lists `FRUITTREE_AZALEA_TOWN` -> `WHT_APRICORN` at index `0x14` |
-| Item balls (`OBJECTTYPE_ITEMBALL`: Super Potion at B1F `10, 3`, TM Rain Dance at B2F `15, 5`) | extracted by `src/import/RomExtractorGen2.lua:2968`; **no runtime handler found in `src/world/gen2/World.lua`** | **missing** - the object data is there, nothing picks it up |
-| `fruittree` at runtime (White Apricorn tree object) | opcode row exists (`src/script/gen2/Opcodes.lua`, `[0x9a]`) and `Vm.lua` references it; the daily-tree store is described in `src/core/gen2/Apricorns.lua` (`save.fruitTrees`) | partial - modelled, not verified end to end in a driver |
-| Wild encounters for Slowpoke Well (grass 3-slot time split, water, fishing) | `src/import/RomExtractorGen2.lua` (Encounters), `src/battle/gen2/Encounter.lua` | implemented per `docs/gold-phase1.md`; not verified for this map specifically |
-| A driver that walks any part of this section | none - `tests/drivers/gold_*.lua` has nothing matching azalea / slowpoke / kurt / bugsy | **missing** |
-
-## 6. Unresolved / verify by hand
-
- **Bug Catcher Al's prize.** The walkthrough says 200G. The asm gives
-  4 (`data/trainers/attributes.asm:215`) x 12 (last mon, L12 Weedle) x 4 = **192G**.
-  Every other figure in the section matches the formula exactly
-  (360 / 440 / 360 / 560 / 200 / 208 / 192 / 1600), so this looks like a
-  walkthrough typo, not a special case.
- **Bugsy's gender.** The walkthrough says "Bugsy and her apprentices" and
-  "she may have the Bug Pokemon". `AzaleaGymGuideText` in `maps/AzaleaGym.asm`
-  says "BUGSY's young, but **his** knowledge of bug #MON is for real". The asm
-  wins.
- **"Liz the Picnicker calls about Moo Moo Milk."** `LizPhoneCallerScript`
-  (`engine/phone/scripts/trainers.asm:234-254`) only does
-  `PhoneScript_GreetPhone_Female`, a `checkflag ENGINE_FLYPOINT_GOLDENROD`
-  rematch gate, `PhoneScript_Random2` and `Phone_GenericCall_Female` /
-  `Phone_CheckIfUnseenRare_Female`. There is no Moo Moo Milk text in her script,
-  and no `MOOMOO` string turned up anywhere under `engine/phone/`. The generic
-  call pool may contain such a line, but it is not attributable to Liz from the
-  map/phone scripts - unresolved.
- **"TM49" listed under *Items found in Azalea Town*.** TM49 is
-  `verbosegiveitem TM_FURY_CUTTER` inside `AzaleaGymBugsyScript`, i.e. found in
-  `MAP_AZALEA_GYM`, not on the town map. Cosmetic, but a bot indexing by map
-  should not look for it outdoors.
- **Battle order inside Slowpoke Well.** The walkthrough's "move on up the
-  stairs", "head down the stairs" prose does not correspond to any `LADDER` or
-  `STAIRCASE` collision inside B1F - the only two ladder cells are the two warps
-  (`17, 15` and `7, 11`). The trainer order it describes (M29 -> F1 -> M2 -> M1)
-  does match the geometry, so the "stairs" are just prose for the corridors.
- **`SLOWPOKE_WELL_B2F` reachability.** I derived "Surf only" from
-  `maps/SlowpokeWellB1F.blk` decoded against `data/tilesets/cave_collision.asm`
-  and `data/collision/collision_permissions.asm`; no script or engine check
-  states it. If a future reader wants a stronger citation, it would have to come
-  from the block data, not from an `EVENT_*`.
- **Gym-trainer skippability.** The claim that Josh, Al and (via the column-7
-  stalk) the twins can be walked past is derived from `maps/AzaleaGym.blk` plus
-  each object's sight field, not asserted anywhere in the asm. The retroactive
-  `setevent` block in `AzaleaGymBugsyScript.FightDone` is direct asm evidence
-  that skipping them is an anticipated state, but the exact dodge path should be
-  confirmed in-game before a driver depends on it.
- **`variablesprite SPRITE_AZALEA_ROCKET, SPRITE_RIVAL`.** This is why
-  `AZALEATOWN_RIVAL` is declared with `SPRITE_AZALEA_ROCKET` in
-  `maps/AzaleaTown.asm`. It also means consts 2 and 12 on that map would draw as
-  the rival if they were still visible after the well is cleared - they are not,
-  because both are hidden by then. Worth a look if a port ever renders them.

-In pokegold the SQUIRTBOTTLE has no Route 36 precondition at all (see
-"Unresolved / verify by hand"), so the opening order is the one a bot should follow.

-| # | Map constant | asm file | Enter via | Leaves via | Why (walkthrough beat) |
-|---|---|---|---|---|---|
-| 1 | `MAP_GOLDENROD_FLOWER_SHOP` | `maps/GoldenrodFlowerShop.asm` | `GOLDENROD_CITY` warp 6 @ (33, 5) | warp 1/2 @ (2,7)/(3,7) -> `GOLDENROD_CITY` 6 | Talk to the teacher for the SQUIRTBOTTLE |
-| 2 | `MAP_ROUTE_35_GOLDENROD_GATE` | `maps/Route35GoldenrodGate.asm` | `GOLDENROD_CITY` warp 13 @ (19, 1) -> gate warp 3 | warp 1/2 @ (4,0)/(5,0) -> `ROUTE_35` 1/2 | Randy hands over Kenya the SPEAROW with FLOWER MAIL |
-| 3 | `MAP_ROUTE_35` | `maps/Route35.asm` | gate warp @ (9,33)/(10,33) | warp 3 @ (3, 5) -> `ROUTE_35_NATIONAL_PARK_GATE` 3 | Six trainers + Officer Dirk, walk north |
-| 4 | `MAP_ROUTE_35_NATIONAL_PARK_GATE` | `maps/Route35NationalParkGate.asm` | warp 3/4 @ (3,7)/(4,7) | warp 1/2 @ (3,0)/(4,0) -> `NATIONAL_PARK` 3/4 | Contest officer; optional entry to the Contest |
-| 5 | `MAP_NATIONAL_PARK_BUG_CONTEST` | `maps/NationalParkBugContest.asm` | script `warp NATIONAL_PARK_BUG_CONTEST, 10, 47` from the south gate (or `33, 18` from the north gate) | contest timer / balls exhausted, or either gate | Optional Tue/Thu/Sat Contest |
-| 6 | `MAP_NATIONAL_PARK` | `maps/NationalPark.asm` | warp 3/4 @ (10,47)/(11,47) | warp 1/2 @ (33,18)/(33,19) -> `ROUTE_36_NATIONAL_PARK_GATE` 1/2 | QUICK CLAW, Beverly, Jack, Krise, William, TM28 DIG |
-| 7 | `MAP_ROUTE_36_NATIONAL_PARK_GATE` | `maps/Route36NationalParkGate.asm` | warp 1/2 @ (0,4)/(0,5) | warp 3/4 @ (9,4)/(9,5) -> `ROUTE_36` 1/2 | Contest results / prize holding |
-| 8 | `MAP_ROUTE_36` | `maps/Route36.asm` | warp 1/2 @ (18,8)/(18,9) | south connection @ y=17 -> `ROUTE_35`; later east connection -> `VIOLET_CITY` | Ice Berry, Psychic Mark, Schoolboy Alan, Sudowoodo, TM08 |
-| 9 | `MAP_ROUTE_35` (again) | `maps/Route35.asm` | north connection from `ROUTE_36` (offset 0) | back north to `ROUTE_36` | Cut the tree, Bug Catcher Arnie, Bird Keeper Bryan, TM04 ROLLOUT |
-| 10 | `MAP_ROUTE_36` (again) | `maps/Route36.asm` | north connection from `ROUTE_35` | **east connection -> `VIOLET_CITY`** | Sudowoodo cleared, then east into Violet City |
-
-Spills into the next section: step 10's east connection
-(`connection east, VioletCity, VIOLET_CITY, 0` in `data/maps/attributes.asm`) drops the
-player into `MAP_VIOLET_CITY`, which belongs to a neighbouring section. Route 37
-(`MAP_ROUTE_37`, north connection off Route 36 with offset 10) is named in this section's
-header but the walkthrough never routes into it; its data is recorded below for
-completeness because the item list ("Blk/Blu/Red Apricorn", "Ice Berry") mixes 36 and 37.

- `TrainerOfficerDirk` - **not** an `OBJECTTYPE_TRAINER` object. It is a plain script that
-  runs `checktime NITE` / `iffalse .NotNight` first, so Dirk only battles at night. Then
-  `checkevent EVENT_BEAT_OFFICER_DIRK`, `playmusic MUSIC_OFFICER_ENCOUNTER`,
-  `winlosstext OfficerDirkBeatenText, 0`, `loadtrainer OFFICER, DIRK`, `startbattle`,
-  `reloadmapafterbattle`, `setevent EVENT_BEAT_OFFICER_DIRK`. A daytime bot will get
-  `OfficerDirkPrettyToughText` and no battle.
- `TrainerJugglerIrwin` / `TrainerBugCatcherArnie` - standard phone trainers. After the
-  win, `checkcellnum PHONE_JUGGLER_IRWIN` / `PHONE_BUG_CATCHER_ARNIE`, then
-  `setevent EVENT_IRWIN_ASKED_FOR_PHONE_NUMBER` / `EVENT_ARNIE_ASKED_FOR_PHONE_NUMBER`

-cut, and Bug Catcher Arnie at (16, 7) sits immediately behind it. Route 36, Route 37 and
-National Park have **no** cuttable blocks (National Park's `.park` entry in

- Every `BugCatchingContestantNAScript` is `faceplayer / opentext / writetext / waitbutton

-  the ones that branch on `EVENT_TEMPORARY_UNTIL_MAP_RELOAD_1` (set by
-  `BugContestResults_FirstPlace`) to say "you won".
- The battle path is `BugCatchingContestBattleScript::`
-  (`engine/events/bug_contest/contest.asm:9`): `loadvar VAR_BATTLETYPE, BATTLETYPE_CONTEST`,
-  `randomwildmon`, `startbattle`, `reloadmapafterbattle`, `readmem wParkBallsRemaining`,

-**Scoring** - `ContestScore` (`04:7cbc`, `engine/events/bug_contest/judging.asm`) sums:
-`MaxHP * 4` (high byte only), then Attack, Defense, Speed, SpclAtk, SpclDef, then a DV
-bonus assembled from bit 1 of each DV nibble, then `remaining HP / 8`, then `+1` if the
-mon is holding an item. Five of the ten AI contestants are rolled by
-`ComputeAIContestantScores`, each picking one of three canned mon/score pairs from
-`BugContestantPointers` (`data/events/bug_contest_winners.asm`) with a 0..7 random
-perturbation. `DetermineContestWinners` keeps a 3-deep podium.
-
-**Prizes** - `BugContestResultsScript` (`40:420e`, `engine/events/std_scripts.asm:275`):
-
-| place | item | no-room fallback flag |
-|---|---|---|
-| 1st | `SUN_STONE` | `EVENT_CONTEST_OFFICER_HAS_SUN_STONE` |
-| 2nd | `EVERSTONE` | `EVENT_CONTEST_OFFICER_HAS_EVERSTONE` |
-| 3rd | `GOLD_BERRY` | `EVENT_CONTEST_OFFICER_HAS_GOLD_BERRY` |
-| consolation | `BERRY` | `EVENT_CONTEST_OFFICER_HAS_BERRY` |
-
-First place also sets `EVENT_TEMPORARY_UNTIL_MAP_RELOAD_1`. The tail of the script clears
-`ENGINE_BUG_CONTEST_TIMER`, sets all twenty `EVENT_BUG_CATCHING_CONTESTANT_*` flags, sets
-`ENGINE_DAILY_BUG_CONTEST`, and resets both gate scenes to their NOOP.

-
-**Scripts of interest**
-
- `SudowoodoScript` (`4b:61aa`) - the gate of this section.
-  `checkitem SQUIRTBOTTLE` / `iftrue .Fight`. Without it: `waitsfx`,
-  `playsound SFX_SANDSTORM`, `applymovement ROUTE36_WEIRD_TREE, SudowoodoShakeMovement`
-  (`tree_shake`), `end` - the tree just wobbles and stays solid.
-  With it: `writetext UseSquirtbottleText`, `yesorno`, `iffalse DidntUseSquirtbottleScript`.
- `WateredWeirdTreeScript::` (`4b:61c1`) - exported so that using the SQUIRTBOTTLE from the
-  PACK reaches the same body (`engine/events/squirtbottle.asm` does
-  `farsjump WateredWeirdTreeScript`). Body: text, shake, `SudowoodoAttackedText`,
-  **`loadwildmon SUDOWOODO, 20`**, `startbattle`, `setevent EVENT_FOUGHT_SUDOWOODO`,
-  `ifequal DRAW, DidntCatchSudowoodo`, `disappear ROUTE36_WEIRD_TREE`,
-  `variablesprite SPRITE_WEIRD_TREE, SPRITE_TWIN`, `reloadmapafterbattle`.
-  Note the ordering: `EVENT_FOUGHT_SUDOWOODO` is set **before** the DRAW check, so a run
-  or a KO still clears the road and still unlocks TM08.
- `DidntCatchSudowoodo` (`4b:61e9`) - `reloadmapafterbattle`,
-  `applymovement ROUTE36_WEIRD_TREE, WeirdTreeMovement_Flee` (two `fast_jump_step UP`),
-  `disappear`, `variablesprite`, `special LoadUsedSpritesGFX`.
- `_Squirtbottle` (`14:4763`, `engine/events/squirtbottle.asm`) - the PACK path.
-  `.CheckCanUseSquirtbottle` requires `wMapGroup == GROUP_ROUTE_36`,
-  `wMapNumber == MAP_ROUTE_36`, `GetFacingObject` to succeed, and that object's movement
-  data to be `SPRITEMOVEDATA_SUDOWOODO`. Anything else prints
-  `_SquirtbottleNothingText`.
- `Route36RockSmashGuyScript` (`4b:61f7`) - `checkevent EVENT_GOT_TM08_ROCK_SMASH` ->
-  `.AlreadyGotRockSmash`; `checkevent EVENT_FOUGHT_SUDOWOODO` -> `.ClearedSudowoodo`
-  (`verbosegiveitem TM_ROCK_SMASH`, `iffalse .NoRoomForTM`,
-  `setevent EVENT_GOT_TM08_ROCK_SMASH`). Before Sudowoodo it just prints
-  `RockSmashGuyText1`.
- `ArthurScript` (`4b:62d4`) - `checkevent EVENT_GOT_HARD_STONE_FROM_ARTHUR` ->
-  `.AlreadyGotStone`; `readvar VAR_WEEKDAY` / `ifnotequal THURSDAY, ArthurNotThursdayScript`;
-  else `setevent EVENT_MET_ARTHUR_OF_THURSDAY`, `verbosegiveitem HARD_STONE`,
-  `iffalse .BagFull`, `setevent EVENT_GOT_HARD_STONE_FROM_ARTHUR`.
- `Route36LassScript` (`4b:621e`) - flavour, branches on `EVENT_FOUGHT_SUDOWOODO`. This is
-  the girl at (51, 8). She is **not** Floria and gives nothing.

-## 3. Blockers and gates
-
-| Gate | Enforced by (file:label) | Requirement | Unlock condition |
-|---|---|---|---|
-| SQUIRTBOTTLE not obtainable | `maps/GoldenrodFlowerShop.asm:FlowerShopTeacherScript` (`57:52d1`) - `checkflag ENGINE_PLAINBADGE` / `iffalse .Lalala` | Plain Badge (Whitney) | beat Whitney; talk to the teacher at (2,4) |
-| Sudowoodo blocks Route 36 | `maps/Route36.asm:SudowoodoScript` (`4b:61aa`) - the object at cell (35,9) with `SPRITEMOVEDATA_SUDOWOODO` is a solid NPC; the script's `checkitem SQUIRTBOTTLE` / `iftrue .Fight` is the only way past | SQUIRTBOTTLE in the PACK | `EVENT_FOUGHT_SUDOWOODO` set by `WateredWeirdTreeScript` (`4b:61c1`); the `disappear` runs on any outcome except a draw-flee, and the flee path disappears it too |
-| SQUIRTBOTTLE from the PACK does nothing elsewhere | `engine/events/squirtbottle.asm:_Squirtbottle` (`14:4763`) `.CheckCanUseSquirtbottle` | map must be `ROUTE_36` and the faced object must carry `SPRITEMOVEDATA_SUDOWOODO` | face the tree first |
-| TM08 ROCK SMASH withheld | `maps/Route36.asm:Route36RockSmashGuyScript` (`4b:61f7`) - `checkevent EVENT_FOUGHT_SUDOWOODO` | Sudowoodo dealt with | talk to the fisher at (44, 9) |
-| East side of Route 35 (Arnie, Bryan, TM04) | `maps/Route35.blk` block `$5b` at block (8,3) = cells x16-17 y6-7; `data/collision/field_move_blocks.asm:14` | CUT, which needs `ENGINE_HIVEBADGE` (`engine/events/overworld.asm:133` `CutFunction.CheckAble`) and a party mon that knows CUT | Azalea's badge + HM01; or enter from Route 36 via the south connection, which is what the walkthrough does |
-| Bug Contest closed | `maps/Route35NationalParkGate.asm:Route35OfficerScriptContest` (`56:5e0c`) and `maps/Route36NationalParkGate.asm:Route36OfficerScriptContest` (`56:67cc`) - `readvar VAR_WEEKDAY`, four `ifequal` bail-outs, plus `checkflag ENGINE_DAILY_BUG_CONTEST` | Tuesday, Thursday or Saturday, and not already run today | set the RTC weekday; `ENGINE_DAILY_BUG_CONTEST` clears on the daily reset |
-| Contest entry refused | same scripts - `readvar VAR_PARTYCOUNT` / `VAR_BOXSPACE` / `special CheckFirstMonIsEgg` / `special ContestDropOffMons` | lead mon is not an EGG, is not fainted, and there is party-or-box room for a caught bug | reorder the party, heal, free a box slot |
-| Kenya not given | `maps/Route35GoldenrodGate.asm:RandyScript` (`56:59ce`) - `readvar VAR_PARTYCOUNT` / `ifequal PARTY_LENGTH, .partyfull` | fewer than 6 party mons | deposit one |

-## 5. Port coverage
-
-| Beat | Port file | Status |
-|---|---|---|
-| Map geometry, warps, bg/object events for all nine maps | `src/import/RomExtractorGen2.lua` (extracted into the cache), consumed by `src/world/gen2/World.lua` / `Map.lua` | implemented (data-driven; nothing map-specific is hand written) |
-| Script bytecode for every label above (`FlowerShopTeacherScript`, `RandyScript`, `SudowoodoScript`, `Route36RockSmashGuyScript`, `ArthurScript`, both contest officers, `BugContestResultsScript`) | `src/script/gen2/Vm.lua` + extracted bytecode | implemented - the opcodes these scripts use (`checkevent`, `checkflag`, `checkitem`, `verbosegiveitem`, `givepoke`, `givepokemail`, `loadwildmon`, `variablesprite`, `appear`/`disappear`, `setscene`, `sdefer`, `askforphonenumber`, `checkcellnum`, `checktime`, `fruittree`) all have branches in `Vm.lua` / `Opcodes.lua` |
-| `VAR_WEEKDAY` (Arthur, Sunny, contest days) | `src/world/gen2/World.lua:1201` `World:weekday`, `World.lua:101` `VAR_WEEKDAY = 0x0b` | implemented |
-| `MAPCALLBACK_OBJECTS` day-of-week NPC swaps | `src/world/gen2/World.lua:5991` `World:runMapCallback`, called from `World.lua:5700` | implemented; assertion driver `tests/drivers/gold_map_callbacks.lua` exists but does **not** cover Route 36 / Route 37 / either park gate |
-| Bug Catching Contest rules, timer, park balls, scoring, AI contestants, prizes | `src/core/gen2/BugContest.lua` (815 lines; transcribed from `bug_contest/judging.asm`, `contest.asm`, `contest_2.asm`, `caught_mon.asm`, `bug_contest_mons.asm`) | implemented - `BugContest.score`, `rollContestant`, `judge`, `prizeFor`, `pickContestants`, `dropOffMons`, `returnMons`, `start/stop/tickTimer`, `chooseWild` |
-| Contest comparison / debug UI | `src/ui/gen2/ContestMenu.lua` | implemented (a comparison screen, not the cart's HUD) |
-| Contest super-tall-grass doubled encounter rate | `src/world/gen2/Permissions.lua:85` `SUPER_TALL_GRASS`, `BugContest.encounterRate` | implemented |
-| Squirtbottle field check | `src/script/gen2/CallAsm.lua:411` `H.CheckCanUseSquirtbottle` (registered as `"14:4786"`), tested in `tests/gen2_callasm_test.lua:224-244` | implemented |
-| **Using the SQUIRTBOTTLE from the PACK** | `src/world/gen2/World.lua:3294` `World:useFieldItem` | **missing** - the dispatch has arms only for `ITEMFINDER`, `BICYCLE`, `SACRED_ASH`, repels, trophy boxes and rods. There is no `SQUIRTBOTTLE` arm, so `_Squirtbottle` is unreachable from the PACK. The talk-to-the-tree path (`SudowoodoScript`'s `checkitem`) still works, which is the route the walkthrough takes |
-| **Item ball pickup** (TM04 on Route 35, TM28 DIG and PARLYZ HEAL in National Park) | extractor reads them (`src/import/RomExtractorGen2.lua:2969` `obj.itemball = readItemBall(...)`) but `src/world/gen2/World.lua:5257` `World:interact` only dispatches on `npc.def.trainer`, strength boulders, `npc.def.scriptKey`, bg events and hidden items | **missing** - `OBJECTTYPE_ITEMBALL` objects have no `scriptKey` by design, and nothing consumes `obj.itemball`. A bot cannot pick up any of this section's three item balls |
-| Hidden item (National Park FULL HEAL, Route 37 ETHER) | `src/world/gen2/HiddenItems.lua`, wired into `World:interact` | implemented |
-| Fruit trees (MYSTERYBERRY, ICE BERRY, the Route 37 apricorns) | `src/core/gen2/Apricorns.lua` + the VM's `fruittree` branch | implemented |
-| Overworld trainers, sight ranges, `loadtrainer` / `startbattle` | `src/world/gen2/Trainers.lua`, `src/battle/gen2/Battle.lua` | implemented |
-| Phone numbers and rematch tiers (Irwin, Arnie, Jack, Beverly, Alan) | `src/core/gen2/Phone.lua` (Jack, Beverly, Irwin, Arnie, Alan all have callee/caller script keys and `..._READY_FOR_REMATCH` event ids) | implemented |
-| Kenya the SPEAROW + FLOWER MAIL | `src/core/gen2/Mail.lua` + `Vm.lua:439` `givepoke` / `Vm.lua:462` `givepokemail` | implemented (extractor resolves `cmd.mail`) |
-| CUT field move + `ENGINE_HIVEBADGE` gate + the Route 35 tree block | `src/world/gen2/FieldMoves.lua:104` (`CUT = "HIVE"`), `FieldMoves.somethingToCut`, `World:tryCutOW` | implemented |
-| Sudowoodo wild battle + DRAW-flee branch | `src/script/gen2/Vm.lua:44` (DRAW), `Vm.lua:836` `loadwildmon`, `World.lua:5067` (`variablesprite` with a raw sprite id) | implemented |
-| Driver / regression coverage for this specific stretch | `tests/drivers/gold_*.lua` | **missing** - there is no driver that walks Route 35 -> National Park -> Route 36, runs a contest, or fights Sudowoodo. `tests/gen2_contest_test.lua` covers the contest rules headlessly; `tests/gen2_callasm_test.lua` covers only the Squirtbottle facing check |

-   exists in pokegold. `maps/GoldenrodFlowerShop.asm` has a `GOLDENRODFLOWERSHOP_FLORIA`
-   object at (5, 6) whose `FlowerShopFloriaScript` only prints text, and the girl on
-   Route 36 at (51, 8) is an anonymous `ROUTE36_LASS1` running `Route36LassScript`, which
-   also only prints text. The SQUIRTBOTTLE comes from `FlowerShopTeacherScript` gated on
-   `ENGINE_PLAINBADGE` alone, with no Route 36 precondition. The described sequence looks
-   like Crystal behaviour that leaked into a Gold/Silver walkthrough.
-2. **Contest Pokemon list.** The walkthrough lists "Caterpie/Weedle, Nincada, Scyther,
-   Pinsir, Volbeat, Wurmple" at "Levels 28-31". `data/wild/bug_contest_mons.asm` has
-   CATERPIE, WEEDLE, METAPOD, KAKUNA, BUTTERFREE, BEEDRILL, VENONAT, PARAS, SCYTHER,
-   PINSIR at levels 7-18 (plus VENOMOTH 30-40 on the `-1` terminator row, which is never
-   selected). NINCADA, VOLBEAT and WURMPLE do not exist in Gen 2 at all. Treat the
-   walkthrough's list and levels as wrong for this game.
-3. **"20 Sport Balls."** The item is `PARK_BALL` (`constants/item_constants.asm:185`),
-   given by `special GiveParkBalls`, count `BUG_CONTEST_BALLS = 20`. "Sport Ball" is the
-   Gen 3+ name.
-4. **"If you win the contest, you can win a Shiny Stone!"** First place gives `SUN_STONE`
-   (`BugContestResults_FirstPlace`, `engine/events/std_scripts.asm:346`). The
-   walkthrough's own item list ("Sun Stone (1st Prize)") agrees; the prose line does not.
-   There is no Shiny Stone in Gen 2.
-5. **"If you catch a Scyther at full HP, it may be worth around 342 points."** Not
-   verifiable from the asm without a concrete mon: `ContestScore` (`04:7cbc`) is
-   `MaxHP*4 + Atk + Def + Spe + SpA + SpD + DVbonus + HP/8 + heldItem`, all taken from the
-   high byte of each stat word. The walkthrough's qualitative claim ("score takes HP into
-   consideration") is confirmed; the specific number is not checked here.
-6. **National Park species list.** The walkthrough lists Butterfree, Weedle, Kakuna,
-   Beedrill, Paras, Venonat, Scyther and Pinsir as "found in National Park". None of them
-   appear in `def_grass_wildmons NATIONAL_PARK`; they are Contest-only
-   (`data/wild/bug_contest_mons.asm`). Sunkern, Caterpie, Metapod, Pidgey and Hoothoot are
-   the only real National Park grass encounters in Gold.
-7. **"Routes 36 & 37" item and species lists are merged.** Everything the walkthrough
-   attributes to "Routes 36 & 37" except the ICE BERRY, HARD STONE and TM08 actually lives
-   on Route 37 (`RED_APRICORN`, `BLU_APRICORN`, `BLK_APRICORN`; Ledyba/Spinarak/Pidgeotto),
-   which this section never enters. Vulpix/Growlithe and Stantler appear on both routes.
-8. **"Route 35 & National Park" item list omits the hidden FULL HEAL** at National Park
-   bg (6, 47) and lists no hidden items at all. Not a contradiction, just incomplete.
-9. **"Head back to Arnie and talk to *her*."** `BUG_CATCHER, ARNIE1` uses the male phone
-   std scripts (`AskNumber1MScript`, `RegisteredNumberMScript`). Cosmetic only.
-10. **"Then, we're ready to head into Route 35 after Liz's offer for a rematch on Route
-    32."** Liz's rematch is a phone event outside this section's maps; no code on any map
-    in this section references it, so it was not resolved here.
-11. **`EVENT_FOUGHT_SUDOWOODO` is set before the DRAW check** in
-    `WateredWeirdTreeScript`, and both the win branch and `DidntCatchSudowoodo` run
-    `disappear ROUTE36_WEIRD_TREE`. So the walkthrough's "catch it or else" is a
-    preference, not a gate - fainting or fleeing still opens the road and still unlocks
-    TM08. Worth confirming in-game that a *black-out* mid-battle does not leave a
-    half-applied state, which the asm alone cannot answer.
-12. **`MAP_NATIONAL_PARK_BUG_CONTEST` warps 2 and 4 point at destination warp 1**, not 2,
-    in `maps/NationalParkBugContest.asm:228,230`. Transcribed verbatim; a bot pathing off
-    those rows should expect the asymmetry rather than assume a typo.

-
-Object-event visibility convention (verified in `engine/overworld/scripting.asm:879-898`): `appear`
-*clears* the flag and `disappear` *sets* it, so **an object is on the map only while its event flag
-is clear.**
-
-**Scripts of interest**
-
- `GoldenrodUndergroundCheckDayOfWeekCallback` (`callback MAPCALLBACK_OBJECTS`): `readvar VAR_WEEKDAY`
-  and appear/disappear the four merchants. Who is standing there:
-  - Sunday: younger brother + granny
-  - Monday: gramps only, and only during `MORN` (`checktime MORN`)
-  - Tuesday / Thursday: **older brother**
-  - Wednesday / Friday: younger brother
-  - Saturday: older brother + granny
-
-  The walkthrough's "500 haircut" therefore only exists on **Tuesday, Thursday or Saturday**.
- `OlderHaircutBrotherScript` (`46:4129`): `readvar VAR_WEEKDAY`, bails to
-  `GoldenrodUndergroundScript_ShopClosed` unless TUE/THU/SAT. Then
-  `checkflag ENGINE_GOLDENROD_UNDERGROUND_GOT_HAIRCUT` (one cut per day, cleared by the daily
-  reset), `yesorno`, `checkmoney YOUR_MONEY, 500`, `special OlderHaircutBrother`, then
-  `takemoney YOUR_MONEY, 500`. `DEF GOLDENRODUNDERGROUND_OLDER_HAIRCUT_PRICE EQU 500` is at the top
-  of the file. The special returns 0/1 (cancel or Egg) or 2/3/4, which the script mirrors into
-  `EVENT_TEMPORARY_UNTIL_MAP_RELOAD_1/2/3` just to pick which of three "looks happier" lines to
-  print.
- `special OlderHaircutBrother` -> `engine/events/haircut.asm:15` -> `HaircutOrGrooming`, weighted
-  roll over `HappinessData_OlderHaircutBrother` (`data/events/happiness_probabilities.asm:1`):
-  30% -> `HAPPINESS_OLDERCUT1`, 50%+1 -> `HAPPINESS_OLDERCUT2`, remainder -> `HAPPINESS_OLDERCUT3`.
-  The actual deltas are `data/events/happiness_changes.asm:13-15`:
-  `+1/+1/+1`, `+3/+3/+1`, `+5/+5/+2` (columns are happiness <100 / <200 / otherwise).
-  The younger brother (300, SUN/WED/FRI) rolls 60%+1 / 30% / rest for `+1/+1/+1`, `+3/+3/+1`,
-  `+10/+10/+4` - **its jackpot row is strictly better than the older brother's**, which the
-  walkthrough does not mention.

-**Which warps are ladders and which are pits.** Derived by decoding each floor's `.blk` against

-Columns x=4 and x=5 are floor from y=14 straight up to y=3, so a bot can enter at (4, 15) or
-(5, 15) and hold UP to reach Jasmine at (5, 3) with no turns. The two statues are the wall tiles at
-(3, 13) and (6, 13); the gym guide stands at (7, 13), reachable from (7, 14).
-
-**Scripts of interest**
-
- `OlivineGymJasmineScript` (`51:4110`, `maps/OlivineGym.asm:10`). Opcode-by-opcode:
-
-  ```
-  faceplayer / opentext
-  checkevent EVENT_BEAT_JASMINE -> iftrue .FightDone
-  writetext Jasmine_SteelTypeIntro / waitbutton / closetext
-  winlosstext Jasmine_BetterTrainer, 0
-  loadtrainer JASMINE, JASMINE1

-  playsound SFX_GET_BADGE / waitsfx
-  setflag ENGINE_MINERALBADGE
-  readvar VAR_BADGES
-  scall OlivineGymActivateRockets
-  .FightDone:
-  checkevent EVENT_GOT_TM23_IRON_TAIL -> iftrue .GotIronTail
-  writetext Jasmine_BadgeSpeech / promptbutton
-  verbosegiveitem TM_IRON_TAIL
-  iffalse .NoRoomForIronTail
-  setevent EVENT_GOT_TM23_IRON_TAIL
-  writetext Jasmine_IronTailSpeech / waitbutton / closetext / end
-  ```
-
-  Two bot-relevant consequences: (a) `winlosstext ..., 0` means there is **no loss-warp script**,
-  losing just blacks you out normally; (b) if the bag has no room in the TM pocket,
-  `verbosegiveitem` returns false and `EVENT_GOT_TM23_IRON_TAIL` is **not** set - re-talking to
-  Jasmine retries the give from `.FightDone`. Keep TM room free.
-
- `OlivineGymActivateRockets` (`51:4159`): the `scall`ed tail, dispatching on the `readvar
-  VAR_BADGES` value that was just pushed:
-
-  ```
-  ifequal 7, .RadioTowerRockets   -> jumpstd RadioTowerRocketsScript
-  ifequal 6, .GoldenrodRockets    -> jumpstd GoldenrodRocketsScript
-  end
-  ```
-
-  `VAR_BADGES` is `CountSetBits` over the two `wBadges` bytes
-  (`engine/overworld/variables.asm:80-86`), so it counts Johto **and** Kanto badges. Since
-  `setflag ENGINE_MINERALBADGE` runs first, MINERALBADGE is included in the count. On the
-  walkthrough's route (Zephyr, Hive, Plain, Fog, Storm, Mineral) the count is **6** and
-  `GoldenrodRocketsScript` fires: `clearevent EVENT_GOLDENROD_CITY_ROCKET_TAKEOVER`
-  (`engine/events/std_scripts.asm:251-253`), which makes the two Rocket grunts appear in Goldenrod
-  City at (28, 20) and (8, 15) (`maps/GoldenrodCity.asm:376-377`). Every gym carries the same
-  `scall` (`maps/VioletGym.asm:31`, `maps/MahoganyGym.asm:34`, ...), so whichever gym hands you
-  badge 6 is the one that arms the Rockets - beating Jasmine *before* Chuck simply moves the
-  trigger to Chuck.
-
- `OlivineGymGuideScript` (`51:4168`): three-way on `EVENT_BEAT_JASMINE`, then
-  `EVENT_JASMINE_RETURNED_TO_GYM`. Text only, no flags written.
- `OlivineGymStatue` (`51:418a`): `checkflag ENGINE_MINERALBADGE`, `jumpstd GymStatue1Script`
-  before, `gettrainername STRING_BUFFER_4, JASMINE, JASMINE1` + `jumpstd GymStatue2Script` after.
-
-**Flags and events**
-
-| constant | defined in | read/written by | meaning for a bot |
-|---|---|---|---|
-| `EVENT_OLIVINE_GYM_JASMINE` (0x6d3) | `constants/event_flags.asm:1141` | set by `InitializeEventsScript`; cleared by `OlivineLighthouseJasmine` | **precondition**: while set, the gym is empty and unbeatable |
-| `EVENT_BEAT_JASMINE` (0x4c1) | `constants/event_flags.asm:710` | set by `OlivineGymJasmineScript` | postcondition of the battle |
-| `ENGINE_MINERALBADGE` (engine flag id 30) | `constants/engine_flags.asm:42`, `data/events/engine_flags.asm:50` (`engine_flag wJohtoBadges, MINERALBADGE`) | `setflag` here, `checkflag` in `OlivineGymStatue` | the badge bit; `MINERALBADGE` bit index in `wJohtoBadges` is `constants/ram_constants.asm:256` |
-| `EVENT_GOT_TM23_IRON_TAIL` (0x0d) | `constants/event_flags.asm:19` | `OlivineGymJasmineScript` | one-time TM guard |
-| `EVENT_JASMINE_RETURNED_TO_GYM` (0x20) | `constants/event_flags.asm:41` | read by `OlivineGymGuideScript` | flavour only inside the gym |
-| `EVENT_GOLDENROD_CITY_ROCKET_TAKEOVER` (0x6cd) | `constants/event_flags.asm` | cleared by `GoldenrodRocketsScript` | side effect of reaching 6 badges |
-
-**Items**
-
-| item | how obtained | source (label / bg_event / hidden) | one-time flag |
-|---|---|---|---|
-| `TM_IRON_TAIL` (TM23, item id `$d6`, `constants/item_constants.asm:243`) | `verbosegiveitem` after the battle | `OlivineGymJasmineScript` | `EVENT_GOT_TM23_IRON_TAIL` |
-| 3500 prize money | battle reward | see below | - |
-
-Prize money check: `TrainerClassAttributes` for Jasmine (`data/trainers/attributes.asm`, the sixth
-gym-leader block) is `db HYPER_POTION, NO_ITEM ; items` and `db 25 ; base reward`.
-`ComputeTrainerReward` (`engine/battle/read_trainer_party.asm:300-317`) sets
-`wBattleReward = 25 * wCurPartyLevel` = `25 * 35` = **875**, and the payout loop in
-`engine/battle/core.asm:2340-2360` adds `wBattleReward` **four times** (`ld c, 4`). 875 x 4 =
-**3500**, which matches the walkthrough exactly. (Note Jasmine's AI holds a `HYPER_POTION`.)
-
-Badge effect check: `BadgeStatBoosts` (`engine/battle/core.asm:6533-6588`) - the comment block
-states "MineralBadge: Defense", and the code deliberately swaps the PlainBadge and MineralBadge
-bits before the every-other-badge walk, boosting the stat at `wBattleMonDefense` by 1/8
-(`BoostStat`). Separately `data/types/badge_type_boosts.asm:7` maps MINERALBADGE to `STEEL` for the
-type-matching trainer-card/boost table. So the walkthrough's "raises your Pokemon's defense
-slightly" is correct.
-
-**Trainers**
-
-| const | class | id | party (`data/trainers/parties.asm` label) | script label | rematch/phone |
-|---|---|---|---|---|---|
-| `JASMINE` / `JASMINE1` | `JASMINE` (trainer class 6, `constants/trainer_constants.asm:42-43`) | 1 | `JasmineGroup` (`0e:5a42`, `data/trainers/parties.asm:53`) | `OlivineGymJasmineScript` | none (gym leaders have no phone row) |
-
-`JasmineGroup`, verbatim (`TRAINERTYPE_MOVES`):
-
-```
-db "JASMINE@", TRAINERTYPE_MOVES
-db 30, MAGNEMITE,  THUNDERBOLT, SUPERSONIC, SONICBOOM, THUNDER_WAVE
-db 30, MAGNEMITE,  THUNDERBOLT, SUPERSONIC, SONICBOOM, THUNDER_WAVE
-db 35, STEELIX,    SCREECH, SUNNY_DAY, ROCK_THROW, IRON_TAIL
-db -1 ; end
-```
-
-EXP check against the walkthrough's numbers: trainer EXP is `base * level / 7 * 3 / 2`.
-Magnemite base exp 89 (`data/pokemon/base_stats/magnemite.asm:8`) -> `89*30/7 = 381`, `*3/2 = 571`.
-Steelix base exp 196 (`data/pokemon/base_stats/steelix.asm:8`) -> `196*35/7 = 980`, `*3/2 = 1470`.
-Both match.
-
-**Wild encounters** - none (`INDOOR`).

-## 4. Bot checklist
-
-Optional Eevee-happiness detour (steps 1-5) can be skipped entirely.
-
-1. **Fly** to `SPAWN_GOLDENROD`. Precondition: `ENGINE_STORMBADGE` set and `ENGINE_FLYPOINT_GOLDENROD` (id 69) set. Postcondition: on `GOLDENROD_CITY`.
-2. `GOLDENROD_CITY`: walk to (11, 29), step onto warp 15. Postcondition: on `GOLDENROD_UNDERGROUND_SWITCH_ROOM_ENTRANCES` at warp 5 (4, 29).
-3. `GOLDENROD_UNDERGROUND_SWITCH_ROOM_ENTRANCES`: walk to (5, 25), step onto warp 4. Postcondition: on `GOLDENROD_UNDERGROUND` at warp 2 (3, 34).
-4. `GOLDENROD_UNDERGROUND`: precondition `VAR_WEEKDAY in {TUESDAY, THURSDAY, SATURDAY}` and `ENGINE_GOLDENROD_UNDERGROUND_GOT_HAIRCUT` clear and money >= 500. Walk to (6, 14) and face RIGHT (the brother stands at (7, 14) facing left); talk. Answer **Yes**, pick the Eevee. Postcondition: `ENGINE_GOLDENROD_UNDERGROUND_GOT_HAIRCUT` set, money -500, Eevee happiness +1/+3/+5.
-5. Retrace warps out (warp 2 at (3, 34) -> switch-room warp 5/6 at (4, 29)/(5, 29) -> `GOLDENROD_CITY`).
-6. **Fly** to `SPAWN_OLIVINE`. Precondition: `ENGINE_FLYPOINT_OLIVINE` (id 70). Postcondition: on `OLIVINE_CITY`.
-7. `OLIVINE_CITY`: walk to (29, 27), step onto warp 9. Postcondition: on `OLIVINE_LIGHTHOUSE_1F` at warp 1 (10, 17).
-8. `1F`: walk to (3, 11), step on ladder-up. -> `2F` (3, 11).
-9. `2F`: walk to (5, 3), ladder-up. -> `3F` (5, 3). (Sailor Huey (9, 3) and Gentleman Alfred (17, 8) are already beaten; their `EVENT_BEAT_*` flags guard re-battle.)
-10. `3F`: walk to (13, 3), ladder-up. -> `4F` (13, 3).
-11. `4F`: walk to the pit at (8, 3) or (9, 3) - "left of Lass Connie at (11, 2)". Step in. -> `3F` (8, 3)/(9, 3).
-12. `3F`: walk to (9, 5), ladder-up. -> `4F` (9, 5).
-13. `4F`: walk to (9, 7), ladder-up. -> `5F` (9, 7). (Alternative: 4F (3, 5) -> 5F (3, 5).)
-14. `5F`: walk to (9, 15), ladder-up. -> `6F` (9, 15). Confirm arrival by `MUSIC_VIOLET_CITY` playing (6F is the only lighthouse floor with it).
-15. `6F`: precondition `SECRETPOTION` in bag and `EVENT_OLIVINE_LIGHTHOUSE_JASMINE` clear. Walk to (8, 9) and face UP (Jasmine at (8, 8) faces down) and talk. Answer **Yes** to `JasmineCureAmphyText`. Sit through ~120 frames of cutscene (`pause 60`, `pause 15`, several `pause 10`). Postcondition: `SECRETPOTION` removed, `EVENT_JASMINE_RETURNED_TO_GYM` set, `EVENT_OLIVINE_GYM_JASMINE` **cleared**, `EVENT_OLIVINE_LIGHTHOUSE_JASMINE` set.
-16. Descend: `6F` pit at (16, 5)/(17, 5) -> `5F`; `5F` pit at (16, 7)/(17, 7) -> `4F`; `4F` pit at (16, 9)/(17, 9) -> `3F`; `3F` pit at (16, 11)/(17, 11) -> `2F`; `2F` pit at (16, 13)/(17, 13) -> `1F`. Then `1F` (10, 17)/(11, 17) facing DOWN -> `OLIVINE_CITY` warp 9 at (29, 27).
-17. `OLIVINE_CITY`: (optional) heal at the Pokecenter, warp 1 at (13, 21). Save before the gym.
-18. `OLIVINE_CITY`: walk to (10, 11), step onto warp 2. Postcondition: on `OLIVINE_GYM` at warp 1 (4, 15).

-20. `OLIVINE_GYM`: hold UP along x=5 from (5, 14) to (5, 4), face UP, talk to Jasmine at (5, 3). Precondition: `EVENT_OLIVINE_GYM_JASMINE` clear, `EVENT_BEAT_JASMINE` clear, a free TM slot. Battle `loadtrainer JASMINE, JASMINE1`.
-21. Win. Postconditions in order: `EVENT_BEAT_JASMINE` set -> `ENGINE_MINERALBADGE` set -> money +3500 -> `VAR_BADGES` re-read -> if it equals 6, `EVENT_GOLDENROD_CITY_ROCKET_TAKEOVER` cleared (Rockets appear in Goldenrod) -> `verbosegiveitem TM_IRON_TAIL` -> `EVENT_GOT_TM23_IRON_TAIL` set.
-22. Leave via (4, 15)/(5, 15) facing DOWN -> `OLIVINE_CITY` warp 2 (10, 11).
-
-Battle notes for the driver: lead a Fire or Fighting attacker; both Magnemite carry
-`THUNDER_WAVE` (paralysis risk) and `SONICBOOM` (fixed 20 damage, ignores type - it will connect on
-a Ground type); Steelix has `IRON_TAIL` and `SUNNY_DAY` (which boosts your own Fire moves too).

-## 6. Unresolved / verify by hand
-
- **"Climb up the Olivine Lighthouse in the EXACT same way you came up."** The ladder/pit graph in
-  section 2 is fully decoded from the `.blk` files and `data/tilesets/lighthouse_collision.asm`, but
-  I did **not** flood-fill each floor to prove the specific walking path between a ladder and the
-  next pit. Steps 8-14 of the checklist are the geometrically obvious route (and the pit at 4F
-  (8, 3)/(9, 3) really is left of Lass Connie at (11, 2)), but the intermediate tile-by-tile route
-  on 3F, 4F and 5F should be confirmed in-game before a driver hard-codes it.
- **"Talk to the man who is running the second/middle shop."** The asm has four merchant objects in
-  one column at x=7: gramps y=11, older brother y=14, younger brother y=15, granny y=21, and
-  `GoldenrodUndergroundCheckDayOfWeekCallback` hides most of them on any given day. "Middle" is
-  therefore day-dependent; the unambiguous identifier is the **500 price**
-  (`GOLDENRODUNDERGROUND_OLDER_HAIRCUT_PRICE`), i.e. the older brother at (7, 14), available
-  TUE/THU/SAT only. The walkthrough does not mention the weekday restriction at all.
- **"Eevee's happiness meter should get a nice boost."** The older brother's roll is +1 (30%),
-  +3 (50%) or +5 (20%) at happiness < 200. The younger brother's top roll is +10. The walkthrough's
-  implied "500 is the better option" is not supported by
-  `data/events/happiness_probabilities.asm` / `data/events/happiness_changes.asm`.
- **"Say Yes to the fact that Ampharos will be cured by the medicine."** Confirmed as a hard
-  requirement (`yesorno` / `iffalse .Refused` at `maps/OlivineLighthouse6F.asm:29-30`), but note the
-  refusal path is *recoverable*: it sets nothing, so the player can simply talk again.
- **EXP values (571 / 1470)** are reproduced by the standard trainer formula from the base-exp bytes
-  I read, but I did not open the EXP-award routine itself to confirm the `*3/2` trainer multiplier
-  in this disassembly; treat those two numbers as arithmetic agreement rather than a code citation.
- **`data/trainers/attributes.asm` Jasmine row**: the file has no per-class labels, only ordered
-  comment headers. I identified Jasmine's row by the `; Jasmine` comment (sixth block, `db 25 ;
-  base reward`, `db HYPER_POTION, NO_ITEM`). If that comment ever drifts from the class order in
-  `constants/trainer_constants.asm`, the 3500 derivation drifts with it.
- The walkthrough's "you can go to the Lake of Rage first" branch is out of scope here; nothing in
-  the Olivine Gym asm checks for it.

-calls `GetBlockLocation`, which halves them - `home/map.asm:2099`). `6,2` is
-therefore block (3,1), covering cells (6..7, 2..3); block `$1e` in
-`data/tilesets/traditional_house_collision.asm` is `FLOOR, FLOOR, FLOOR, LADDER`,
-putting the LADDER on cell `7,3` - exactly the warp row above.

-  `setevent EVENT_LANCE_HEALED_YOU_IN_TEAM_ROCKET_BASE`, then `readvar VAR_FACING`
-  picks one of two exit movements and `disappear TEAMROCKETBASEB2F_LANCE`.
-  **This is a hard ordering dependency**: the boss ambush coord events only exist
-  on scene 1, so the transmitter room cannot be entered until Lance has healed you.
- `TeamRocketBaseB2FLockedDoor` (`45:4e8f`): `conditional_event` on
-  `EVENT_OPENED_DOOR_TO_ROCKET_HIDEOUT_TRANSMITTER`; `.Script` checks
-  `EVENT_LEARNED_HAIL_GIOVANNI`. If known: `playsound SFX_ENTER_DOOR`,

- `RocketElectrode1/2/3`: `cry ELECTRODE`, `loadwildmon ELECTRODE, 23`, `startbattle`.
-  `iftrue TeamRocketBaseB2FReloadMap` covers the "you lost/fled" path. After all three
-  events are set, the player is auto-walked out by
-  `RocketBasePlayerLeavesElectrodesMovement1/2/3` into `RocketBaseElectrodeScript`.
-  No `BATTLETYPE_*` is armed here, so these are catchable ordinary wild battles.
- `RocketBaseElectrodeScript` (`45:4e3c`) - the section's payoff:

-TM numbering check: `constants/item_constants.asm` `add_tm THIEF ; ee` is the 46th
-`add_tm` (the `const ITEM_C3` / `const ITEM_DC` holes do not consume TM numbers), so

-Sliding rule (`engine/overworld/player_movement.asm`): `CheckIceTile` on the tile
-you land on -> `STEP_ICE`; `.CheckForced` / `CheckStandingOnIce` re-injects the same

-wall, or hit an NPC.

-Reaching `2,14` from the entrance: `UP` (to `4,16`), `LEFT` (`3,16`), `LEFT`

-7. B1F: talk to `GRUNTM_16` at `(2,4)` (sight 3, faces RIGHT - approaching from the east triggers him). Post: `EVENT_BEAT_ROCKET_GRUNTM_16`.
-8. B1F: cross the trap field x1..5 / y7..13 using only the safe cells listed in section 2, or accept the one-shot `BATTLETYPE_TRAP` battles. Optional: hidden REVIVE by facing `(3,11)`.
-9. B1F: battle `SCIENTIST JED` at `(18,12)` (sight 3, faces LEFT). Post: `EVENT_BEAT_SCIENTIST_JED`. Talk again for the warp-panel hint.
-10. B1F: stand at `(19,12)`, face UP, press A on the bg event at `(19,11)`. Post: `EVENT_TURNED_OFF_SECURITY_CAMERAS` + `EVENT_SECURITY_CAMERA_1..5`.

-## 5. Port coverage
-
-| Beat | Port file | Status |
-|---|---|---|
-| Map headers / warps / coord events / bg events / objects for all six maps | `src/import/RomExtractorGen2.lua`, `src/world/gen2/Map.lua` | implemented (generic extraction, nothing map-specific needed) |
-| Map scenes + `sdefer` scene scripts | `src/world/gen2/World.lua` (`World:scene`, `mapScenes`), `src/script/gen2/Vm.lua` (`sdefer`, `setscene`, `setmapscene`) | implemented |
-| Coord-event trip-wires | `src/world/gen2/World.lua` (coord event dispatch) | implemented |
-| `changeblock` (mart staircase, both password doors) | `src/script/gen2/Vm.lua:1006` - the comment cites `MahoganyMart1F`'s `changeblock 6, 2, $1e` and cell `(7,3)` by name | implemented |
-| `BGEVENT_IFNOTSET` / `conditional_event` (both password doors) | `src/world/gen2/World.lua:5147 World:bgEventAt` only matches `(ev.kind or 0) == 0`; `src/world/gen2/HiddenItems.lua` handles kind 7 | **missing** - pressing A on the transmitter door or Giovanni's door does nothing in the port |
-| Ice sliding (`STEP_ICE`, `CheckStandingOnIce` forced d-pad) | `src/world/gen2/Permissions.lua:128 ICE` exists but is only consumed by `FieldMoves.canEncounterWildMon`; `World:movePlayer` picks step frames from `Bike.stepFrames` only | **missing** - Mahogany Gym floor behaves as ordinary floor, so the puzzle and the trainer sight lines are wrong |
-| Trainer sight range / approach | `src/world/gen2/Trainers.lua` (`Trainers.sees`, `Trainers.approach`) | implemented (`sight 0` on GruntF5 falls out naturally) |
-| `itemball` / `hiddenitem` | `src/script/gen2/CallAsm.lua`, `src/world/gen2/HiddenItems.lua` | implemented |
-| `verbosegiveitem HM_WHIRLPOOL` | `src/script/gen2/Vm.lua`, `src/script/gen2/Opcodes.lua` | implemented |
-| Whirlpool field move + GLACIERBADGE gate | `src/world/gen2/FieldMoves.lua:109` (`WHIRLPOOL = "GLACIER"`), `.somethingToWhirlpool`, `.whirlpoolFromMenu`, `.tryWhirlpoolOW`, `WHIRLPOOL_BLOCKS` | implemented |
-| `loadwildmon` + `BATTLETYPE_TRAP` | `src/world/gen2/World.lua:4587` (names "TRAP 9 (the Rocket base)"), `src/script/gen2/Vm.lua:699` | implemented |
-| `special HealParty` / `FadeOutToWhite` / `FadeInFromWhite` / `PlayMapMusic` / `ReloadSpritesNoPalettes` / `FadeOutToBlack` / `FadeInFromBlack` / `RestartMapMusic` / `FadeOutMusic` | `src/script/gen2/Specials.lua:450, 992-1066` | implemented |
-| `moveobject` / `appear` / `disappear` / `applymovement` / `follow` / `showemote` | `src/script/gen2/Vm.lua`, `src/script/gen2/Movement.lua`, `src/world/gen2/World.lua` | implemented |
-| `jumpstd` (`TeamRocketOathScript`, `GymStatue1/2Script`, `PokecenterSignScript`, `RadioTowerRocketsScript`) | `src/script/gen2/Vm.lua:742`, `data/generated/std_scripts.lua` via `World.lua:635` | implemented (generic) |
-| `readvar VAR_BADGES` for `MahoganyGymActivateRockets` | `src/world/gen2/World.lua:117,1240` | implemented |
-| `specialphonecall SPECIALCALL_WEIRDBROADCAST` | `src/script/gen2/Vm.lua:1364` stores the id; `src/core/gen2/Phone.lua` delivers | implemented |
-| `ENGINE_ROCKET_SIGNAL_ON_CH20` radio behaviour | `src/ui/gen2/Pokegear.lua:816-821, 1097` | implemented |
-| Driver coverage for this stretch | `tests/drivers/gold_*.lua` - none touches Mahogany, the hideout or Pryce (`gold_icepath_boulder.lua` is the only Mahogany-adjacent one, and it is Ice Path boulders) | **missing** |
-
-The two "missing" rows are the blocking ones: without `BGEVENT_IFNOTSET` the
-hideout cannot be completed, and without ice sliding the gym cannot be crossed.

-
-## 6. Unresolved / verify by hand
-
- **Floor labels in the walkthrough are wrong past the first password.** It says
-  "go up the stairs at the upper-right part of the floor, then head left on Negative
-  Floor 2 ... Head up the stairs to Negative Floor 1. Head right and then before you
-  reach the locked door, your rival will come." The rival coord event
-  (`8,10`) and Giovanni's office are both on **B3F**, not B1F. The route is
-  B3F(right) -> B2F(top) -> B3F(left). Verified by flood-filling
-  `maps/TeamRocketBaseB2F.blk` / `maps/TeamRocketBaseB3F.blk`: the four B2F warps
-  and four B3F warps sit in disconnected rooms, and B2F warp 2 `(3,2)` reaches
-  B3F `(3,2)` which is the region containing `8,10`.
- **Boarder Ronald's party order.** Walkthrough lists Seel 24 / Seel 24 / Dewgong 25;
-  `data/trainers/parties.asm` `BOARDER (1)` is SEEL 24, DEWGONG 25, SEEL 24.
-  Same three mon, different lead order. Same class of discrepancy for
-  `GRUNTM_18` (walkthrough Rattata/Rattata/Zubat, asm Rattata/Zubat/Rattata).
- **Item list is incomplete.** The walkthrough's "Items in the Team Rocket Hideout"
-  block lists six; the asm has ten: the six named plus `FULL_HEAL` and `DIRE_HIT`
-  item balls on B3F (mentioned later in the prose) and two hidden items the
-  walkthrough never mentions - `REVIVE` at B1F `(3,11)` and `FULL_HEAL` at B2F
-  `(26,7)`.
- **"Every time you pass one of those statues, two Team Rocket grunts will fight
-  you"** is right, but the walkthrough implies only two statues on the first floor.
-  There are five (`bg_event` at `24,1`, `6,1`, `24,5`, `8,15`, `22,15`) with eight
-  trigger cells, i.e. up to ten grunt battles if none are skipped.
- **`EVENT_TEAM_ROCKET_BASE_POPULATION` is dead.** It is the shared visibility flag
-  of eleven base NPCs and is read by all eight `SecurityCamera*` scripts, but a
-  full-tree grep finds no `setevent`, `clearevent` or `disappear` that writes it.
-  Those `checkevent ... iftrue NoSecurityCamera` arms therefore never take, and the
-  Rocket NPCs stay on the maps forever - including after the hideout is cleared.
-  Flagged in case a bot author expects the base to empty out.
- **Lance's three right-hand Electrodes are never battled.** `RocketElectrodeN`
-  disappears both members of a mirrored pair, and the objects at `22,5`/`22,7`/`22,9`
-  point at the no-op `ObjectEvent` script. The walkthrough's "Lance runs to the right
-  to take the Electrodes on the right" is flavour; the game just hides them.
- **Exact reachability of `19,11` (the secret switch)** was checked by collision
-  (`19,11` is a WALL, `19,12` is FLOOR and in the single B1F region), but the
-  in-game facing direction for the `BGEVENT_READ` was not observed running - the
-  bg event type is `BGEVENT_READ`, not `BGEVENT_UP`, so any adjacent facing should
-  work; worth confirming on hardware if a driver misses it.
- The gym slide table in section 2 was produced by simulating
-  `engine/overworld/player_movement.asm`'s ice rule against the decoded
-  `maps/MahoganyGym.blk`, treating NPCs as blockers. It reproduces every direction
-  string in the walkthrough, but it has not been executed in an emulator.

-# Section 15 - Mount Mortar and Dark Cave
-
-Source: `../section-15-mount-mortar-and-dark-cave.txt`
-Maps covered: `MAP_MOUNT_MORTAR_1F_OUTSIDE`, `MAP_MOUNT_MORTAR_1F_INSIDE`,
-`MAP_MOUNT_MORTAR_2F_INSIDE`, `MAP_MOUNT_MORTAR_B1F`,
-`MAP_DARK_CAVE_BLACKTHORN_ENTRANCE`, `MAP_DARK_CAVE_VIOLET_ENTRANCE`.
-Touched in passing (owned by neighbouring sections): `MAP_MAHOGANY_TOWN`,
-`MAP_ROUTE_42`, `MAP_BLACKTHORN_CITY`, `MAP_ROUTE_45`, `MAP_ROUTE_31`,
-`MAP_ROUTE_46`.
-
-Badges / key milestones in this section: **no badge**. The milestones are
-`EVENT_BEAT_BLACKBELT_KIYO` + `EVENT_GOT_TYROGUE_FROM_KIYO` (a free level 10
-`TYROGUE`, the only one in the game) and `EVENT_GOT_BLACKGLASSES_IN_DARK_CAVE`.
-Everything else here is optional loot. Nothing in this section gates any later
-section.
-
-A note on coordinates: every table below is transcribed verbatim from the map's
-`_MapEvents` block in the named `maps/*.asm` file. `warp_event`, `coord_event`,
-`bg_event` and `object_event` all share one coordinate space (the
-`object_event` macro in `macros/scripts/maps.asm` applies the +4 border offset
-itself), so the numbers are directly comparable. A map declared
-`map_const NAME, W, H` spans x in `0 .. 2W-1` and y in `0 .. 2H-1`.
-
-A note on the `event flag` column of `object_event`:
-`engine/overworld/map_objects_2.asm` `CheckObjectFlag` **hides** the object when
-the flag is set, and `-1` means always visible. So for a Poke Ball, "flag set =
-already taken = gone".
-
-A note on darkness: all six maps in this section are `PALETTE_DARK` in
-`data/maps/maps.asm`. `engine/tilesets/timeofday_pals.asm`
-`ReplaceTimeOfDayPals` (`23:43e9`) sends `PALETTE_DARK` down `.NeedsFlash`,
-which writes `DARKNESS_PALSET` unless `STATUSFLAGS_FLASH_F` is set in
-`wStatusFlags`. That bit is set by `BlindingFlash` (`engine/events/field_moves.asm`)
-and cleared by `ResetFlashIfOutOfCave` (`home/flag.asm`, `00:2f1d`) on any map
-whose `wEnvironment` is `ROUTE` or `TOWN`. **A bot must re-cast Flash every time
-it re-enters, including after every Fly.**

-| 2 | `MAP_ROUTE_42` | `maps/Route42.asm` | east connection from Mahogany, or warps 1/2 at (0,8)/(0,9) from the Ecruteak gate | warp 3 (10,5) west entrance, warp 4 (28,9) middle entrance, warp 5 (46,7) east entrance -> `MOUNT_MORTAR_1F_OUTSIDE` warps 1/2/3 | "three cave entrances to Mt. Mortar" |

-
-Spill into the next section: the walkthrough's video links name Blackthorn Gym,
-Route 45/46, Tohjo Falls, Routes 26/27, Victory Road and the Elite Four, but its
-**prose** stops at "head back south to actually take Route 45". `MAP_ROUTE_45`
-proper, `MAP_ROUTE_46`, `MAP_BLACKTHORN_GYM` and everything past them belong to
-the next section; only the Route 45 warp that reaches Dark Cave is documented
-here.
-
-`MAP_DARK_CAVE_VIOLET_ENTRANCE` is also reachable from `ROUTE_46` warp 3 at
-(14,5) (-> Dark Cave warp 3 at (35,33)) and from `ROUTE_31` warp 3; the earlier
-sections that visit Route 31 already touch the north end of this map. This
-section only walks it top-to-bottom-left, from the Blackthorn side out to
-Route 31.

-
-Bot-relevant control flow:
-
- The battle is unconditional on first talk (no `checkevent` guard before
-  `loadtrainer`), and the win-flag write is **after** `startbattle`, so a
-  blackout means the whole script re-runs from the top.
- `readvar VAR_PARTYCOUNT` / `ifequal PARTY_LENGTH` is the "you have no room"
-  branch. `PARTY_LENGTH` is 6. **If the party is full, `EVENT_BEAT_BLACKBELT_KIYO`
-  is already set but `EVENT_GOT_TYROGUE_FROM_KIYO` is not**, so re-talking
-  re-enters at `.BeatKiyo` and offers the Tyrogue again. This is why the
-  walkthrough tells you to free a slot in advance - but it is recoverable, not
-  missable.
- `givepoke TYROGUE, 10` - level 10, no held item, no nickname prompt in this
-  form of the opcode.

-`MountMortarB1FBoulder` - `jumpstd StrengthBoulderScript`, same as 1F Inside.

-## 3. Blockers and gates
-
-| Gate | Enforced by (file:label) | Requirement | Unlock condition |
-|---|---|---|---|
-| Darkness on all six maps | `engine/tilesets/timeofday_pals.asm` `ReplaceTimeOfDayPals` (`23:43e9`) `.NeedsFlash` -> `DARKNESS_PALSET`, because `data/maps/maps.asm` lines 127-130 / 148-149 all say `PALETTE_DARK` | FLASH cast, i.e. `STATUSFLAGS_FLASH_F` set in `wStatusFlags` | `engine/events/overworld.asm` `FlashFunction.CheckUseFlash` (`03:48f1`): `ENGINE_ZEPHYRBADGE` **and** `wTimeOfDayPalset == DARKNESS_PALSET`. The bit is cleared by `home/flag.asm` `ResetFlashIfOutOfCave` (`00:2f1d`) on any `ROUTE`/`TOWN` map, so **re-cast after every exit and every Fly** |
-| Mt. Mortar middle entrance (`ROUTE_42` warp 4 at (28,9)) | terrain: the tile is across water on Route 42 | SURF | `engine/events/overworld.asm` `SurfFunction` (`03:493b`), `.TrySurf` arm / `TrySurfOW` (`03:4a06`): `ENGINE_FOGBADGE` + a party member knowing SURF |
-| The lake and the waterfall between 1F Outside and 2F | terrain on `MountMortar1FOutside.blk`; the only route to warp 4 at (17,5) | SURF, then WATERFALL | `WaterfallFunction.TryWaterfall` (`03:4af6`) / `TryWaterfallOW` (`03:4b5f`): `ENGINE_RISINGBADGE`, then `CheckMapCanWaterfall` - **player must be facing UP and the tile ABOVE (`wTileUp`) must be a waterfall tile** |
-| `MOUNTMORTAR1FINSIDE_BOULDER` at (21,43) | `MountMortar1FBoulder` -> `jumpstd StrengthBoulderScript` -> `AskStrengthScript` (`03:4d4e`) | STRENGTH toggled on | `TryStrengthOW` (`03:4d7b`): party knows STRENGTH **and** `ENGINE_PLAINBADGE` **and** `BIKEFLAGS_STRENGTH_ACTIVE_F` set. `StrengthFunction.TryStrength` (`03:4cf1`) only checks the badge. Note `ResetBikeFlags` clears the active bit on **every map load** - Strength must be re-activated per floor |
-| `MOUNTMORTARB1F_BOULDER` at (9,10) | `MountMortarB1FBoulder`, same std script | STRENGTH | as above. This is the walkthrough's "move the rock with HM Strength to get out"; the alternative is an Escape Rope |
-| Kiyo's Tyrogue | `MountMortarB1FKiyoScript` `readvar VAR_PARTYCOUNT` / `ifequal PARTY_LENGTH, .NoRoom` | 5 or fewer party members | free a slot and re-talk; `EVENT_BEAT_BLACKBELT_KIYO` stays set so the battle is not repeated |
-| Dark Cave water crossings (both entrances) | terrain | SURF | `ENGINE_FOGBADGE` as above |
-| `DARKCAVEVIOLETENTRANCE_ROCK1..4` | `DarkCaveVioletEntranceRock` -> `jumpstd SmashRockScript` -> `AskRockSmashScript` (`03:4f60`) | a party member knowing ROCK SMASH (TM08) | `HasRockSmash` (`03:4f7f`) - **no badge check at all** for Rock Smash |
-| Fly between Mahogany and Blackthorn | `engine/events/overworld.asm:545` (the `.TryFly` arm of the Fly jumptable) `ld de, ENGINE_STORMBADGE` | `ENGINE_STORMBADGE` + the destination's `ENGINE_FLYPOINT_*` (`constants/engine_flags.asm:87`, `:89`) | both flypoints are set by visiting the towns in earlier sections |
-
-Badge constants used above: `ENGINE_ZEPHYRBADGE` (`constants/engine_flags.asm:38`),
-`ENGINE_PLAINBADGE` (`:40`), `ENGINE_FOGBADGE` (`:41`), `ENGINE_STORMBADGE`
-(`:43`), `ENGINE_RISINGBADGE` (`:45`). All are checked through
-`engine/events/overworld.asm` `CheckBadge` (line 50), which prints
-"Badge required" and returns carry.
-
-**Nothing in this section gates anything else.** Both Mt. Mortar and Dark Cave
-are entirely optional; a bot that skips them loses only items, the Tyrogue and
-the Blackglasses.

-| **ROCK SMASH as a field move** | `src/script/gen2/CallAsm.lua:346-350` implements `HasRockSmash`, but line 526 stubs `RockMonEncounter` with the note "ROCK SMASH has no field-move path yet; RockMonMaps is unported"; `World:interact`'s tile-event chain (`World.lua:5301-5308`) lists cut / whirlpool / waterfall / headbutt / surf and **not** rock smash, and nothing in `src/` references `SPRITEMOVEDATA_SMASHABLE_ROCK` | **missing** - the four Dark Cave Violet rocks cannot be broken, and the Krabby/Shuckle table is unreachable |

-No driver in `tests/drivers/gold_*.lua` visits Mt. Mortar or Dark Cave.

-
-## 6. Unresolved / verify by hand
-
-1. **The walkthrough's Mt. Mortar item list is the HGSS list, not the GS list.**
-   It names Carbos, Escape Rope x2, Full Restore, Hyper Potion x2, Max Ether,
-   Max Potion, Max Revive, PP Up, Rare Candy, Dragon Scale and "TM40 Aerial
-   Ace". What is actually in `maps/MountMortar*.asm` is: ETHER, GUARD_SPEC,
-   hidden HYPER_POTION (1F Outside); ESCAPE_ROPE, MAX_REVIVE, HYPER_POTION,
-   hidden MAX_REPEL (1F Inside); MAX_POTION, RARE_CANDY, TM_DEFENSE_CURL,
-   DRAGON_SCALE, ELIXER, ESCAPE_ROPE, hidden FULL_RESTORE (2F Inside);
-   HYPER_POTION, FULL_HEAL, hidden MAX_REVIVE (B1F). **No CARBOS, no PP_UP, no
-   MAX_ETHER, no IRON anywhere in Mt. Mortar.** TM40 is the right *number* but
-   the move is DEFENSE_CURL (`constants/item_constants.asm:261`); Aerial Ace is
-   a Gen 3 move that does not exist in this disassembly.
-2. **"grab the free Iron on the cliff" (1F Inside, after coming down from 2F).**
-   There is no IRON object on any Mt. Mortar map. The nearest items to warp 6 at
-   (9,9) are the MAX_REVIVE ball at (16,10) and the hidden MAX_REPEL bg event at
-   (31,9). Treat "Iron" as an HGSS-only pickup.
-3. **"surf clockwise around and reach a Hyper Potion and a Max Ether."** There is
-   no MAX_ETHER in Mt. Mortar. If the intended floor is B1F (the ladder from the
-   central entrance) the pair is HYPER_POTION (31,17) + FULL_HEAL (4,16); if 2F,
-   the closest analogue is ELIXER (8,9). Which one the author meant could not be
-   determined from the asm.
-4. **Kiyo's prize money and EXP yields.** The walkthrough gives 816G and
-   1012/1020 EXP. `data/trainers/parties.asm` only carries the class, name, type
-   byte and party; the money formula lives in the battle engine's
-   `data/trainers/attributes.asm` base-money table times level, which was not
-   opened for this document. The party itself is verified: L34 HITMONLEE, L34
-   HITMONCHAN, `TRAINERTYPE_NORMAL` (default moves, no held items).
-5. **"a giant room where you can zig zag around ... and get two items, to include
-   a Hyper Potion and Escape Rope."** `MOUNT_MORTAR_1F_INSIDE` actually holds
-   *three* balls (ESCAPE_ROPE (33,22), MAX_REVIVE (16,10), HYPER_POTION (12,21))
-   plus a hidden MAX_REPEL - but MAX_REVIVE and the hidden item sit on the
-   section of the map only reachable from 2F, which is presumably why the
-   walkthrough counts two.
-6. **"The west entrance and east entrance lead to each other."** All three Route
-   42 doors land on the same map, `MOUNT_MORTAR_1F_OUTSIDE`; the west/east link
-   runs through `MOUNT_MORTAR_1F_INSIDE` via warp pairs 5/6 (at y=21) and 8/9
-   (at y=13). The blk files were not decoded, so the exact walkable path between
-   any two of these warps is not verified here - only the warp graph is.
-7. **Dark Cave Pokemon list.** The walkthrough lists Zubat, Golbat, Geodude,
-   Graveler, Magikarp and Wobbuffet - that is the `DARK_CAVE_BLACKTHORN_ENTRANCE`
-   table exactly. It omits DUNSPARCE, which is slot 7 of
-   `DARK_CAVE_VIOLET_ENTRANCE` and is on the map the route exits through.
-8. **Dark Cave item list.** The walkthrough lists Blackglasses, Full Heal, Hyper
-   Potion, Revive and TM13. The Full Heal (36,22) and Hyper Potion (35,9) are on
-   `DARK_CAVE_VIOLET_ENTRANCE`'s north-east lobe, which this route does not pass
-   through; the hidden ELIXER at (26,3) is not mentioned at all. The POTION at
-   (6,8) is named in the prose but missing from the list.
-9. **The Shuckle/Krabby rock-smash table** (`data/wild/treemon_maps.asm:46`,
-   `data/wild/treemons.asm:91`) is real and reachable at
-   `DARK_CAVE_VIOLET_ENTRANCE`, but the walkthrough never mentions it. Worth
-   flagging to a bot author as a cheap Shuckle source.
-10. **`MOUNT_MORTAR_1F_OUTSIDE` object 2 flag naming.** The item is
-    `GUARD_SPEC` but the event flag is `EVENT_MOUNT_MORTAR_1F_OUTSIDE_REVIVE`
-    (`constants/event_flags.asm:1053`). Verbatim from the disassembly; not a
-    transcription error here, but it will look like one to anyone grepping by
-    item name.
-11. **Mahogany Town and Blackthorn City interiors** (Poke Center, Mart, gym) were
-    not opened for this document - only their `data/maps/maps.asm` header rows
-    and `data/maps/spawn_points.asm` entries. Those maps belong to neighbouring
-    sections.

-Important structural fact the walkthrough hides: **Gold/Silver Victory Road is a

-third floor" are three vertically stacked regions of the same map joined by
-`warp_event` rows whose destination map is `VICTORY_ROAD` itself. Every "ladder"

-## 2. Maps
-
-### MAP_VICTORY_ROAD
-
- Script: `maps/VictoryRoad.asm` (included from `data/maps/scripts.asm:24`)
- Blocks: `maps/VictoryRoad.blk` (360 bytes; `data/maps/blocks.asm:962`)
- Header: `data/maps/maps.asm:160`
-  `map VictoryRoad, TILESET_CAVE, CAVE, LANDMARK_VICTORY_ROAD, MUSIC_VICTORY_ROAD, TRUE, PALETTE_NITE, FISHGROUP_SHORE`
-  (per the `map` macro at the head of `data/maps/maps.asm`: tileset, environment,
-  location, music, phone-service flag TRUE = phone calls suppressed, time-of-day
-  palette, fishing group.)
- Attributes: `data/maps/attributes.asm:494` `map_attributes VictoryRoad, VICTORY_ROAD, $1d` - border block `$1d`, and **no `connection` rows follow**, so the map has no overworld connections.
- Dimensions: `constants/map_constants.asm:147` `map_const VICTORY_ROAD, 10, 36` -> 10x36 blocks = **20x72 walk cells**. Group `DUNGEONS` (group 3), map id 82.
- Scene variable: `data/maps/scenes.asm:60` `scene_var VICTORY_ROAD, wVictoryRoadSceneID` (sym `01:d6eb`)
- Callbacks: `def_callbacks` is empty - no `MAPCALLBACK_*` for this map.
- Connections: none.
-
-**Warps** (`def_warp_events`, transcribed from `maps/VictoryRoad.asm:242-252`)
-
-| idx | x | y | destination map | dest warp |
-|---|---|---|---|---|
-| 1 | 9 | 67 | `VICTORY_ROAD_GATE` | 5 |
-| 2 | 1 | 49 | `VICTORY_ROAD` | 3 |
-| 3 | 1 | 35 | `VICTORY_ROAD` | 2 |
-| 4 | 13 | 31 | `VICTORY_ROAD` | 5 |
-| 5 | 13 | 17 | `VICTORY_ROAD` | 4 |
-| 6 | 17 | 33 | `VICTORY_ROAD` | 7 |
-| 7 | 17 | 19 | `VICTORY_ROAD` | 6 |
-| 8 | 0 | 11 | `VICTORY_ROAD` | 9 |
-| 9 | 0 | 27 | `VICTORY_ROAD` | 8 |
-| 10 | 13 | 5 | `ROUTE_23` | 3 |
-
-Self-warp pairs, as a bot should read them: 2<->3, 4<->5, 6<->7, 8->9.
-Warp 8's tile is `COLL_PIT` and warp 9's tile is plain `COLL_FLOOR`, so **warp 9
-never fires**: the hole at (0,11) is one-way down to (0,27). (Tile kinds verified
-below.)
-
-**Coord events** (`def_coord_events`, `maps/VictoryRoad.asm:254-256`)
-
-| scene | x | y | script label | effect |
-|---|---|---|---|---|
-| `SCENE_VICTORYROAD_RIVAL_BATTLE` (0) | 12 | 8 | `VictoryRoadRivalLeft` (sym `42:59ba`) | rival is teleported to (18,11), walks LEFTx6 + UPx2 to (12,9), battle, then leaves DOWNx2 + RIGHTx6 |
-| `SCENE_VICTORYROAD_RIVAL_BATTLE` (0) | 13 | 8 | `VictoryRoadRivalRight` (sym `42:59dd`) | rival walks from (18,13) UPx2 + LEFTx5 + UPx2 to (13,9), battle, then leaves DOWNx2 + RIGHTx5 + DOWNx2 |
-
-These two tiles are the entire width of the corridor that leads to the exit
-(y=8 is walkable only at x=6,7 and x=12,13), so the ambush is unavoidable.
-
-**BG events** (`def_bg_events`, `maps/VictoryRoad.asm:258-260`)
-
-| x | y | type | script/item |
-|---|---|---|---|
-| 3 | 29 | `BGEVENT_ITEM` | `VictoryRoadHiddenMaxPotion` = `hiddenitem MAX_POTION, EVENT_VICTORY_ROAD_HIDDEN_MAX_POTION` |
-| 3 | 65 | `BGEVENT_ITEM` | `VictoryRoadHiddenFullHeal` = `hiddenitem FULL_HEAL, EVENT_VICTORY_ROAD_HIDDEN_FULL_HEAL` |
-
-Both target tiles are `COLL_WALL`, i.e. the player stands next to them and
-presses A into the wall. (3,29) is faced from (2,29), (4,29) or (3,28);
-(3,65) is faced from (2,65), (4,65), (3,64) or (3,66).
-
-**Object events** (`def_object_events`, `maps/VictoryRoad.asm:262-268`)
-
-Column order follows the `object_event` macro in `macros/scripts/maps.asm:113`:
-x, y, sprite, movement, radius x, radius y, hour1, hour2, palette, type, sight,
-script, event flag.
-
-| const | sprite | x | y | movement | type | script label | event flag |
-|---|---|---|---|---|---|---|---|
-| `VICTORYROAD_RIVAL` | `SPRITE_RIVAL` | 18 | 13 | `SPRITEMOVEDATA_STANDING_UP` | `OBJECTTYPE_SCRIPT` | `ObjectEvent` (shared ROM0 stub, sym `00:2812`) | `EVENT_RIVAL_VICTORY_ROAD` |
-| `VICTORYROAD_POKE_BALL1` | `SPRITE_POKE_BALL` | 3 | 28 | `SPRITEMOVEDATA_STILL` | `OBJECTTYPE_ITEMBALL` | `VictoryRoadTMEarthquake` = `itemball TM_EARTHQUAKE` | `EVENT_VICTORY_ROAD_TM_EARTHQUAKE` |
-| `VICTORYROAD_POKE_BALL2` | `SPRITE_POKE_BALL` | 12 | 48 | `SPRITEMOVEDATA_STILL` | `OBJECTTYPE_ITEMBALL` | `VictoryRoadMaxRevive` = `itemball MAX_REVIVE` | `EVENT_VICTORY_ROAD_MAX_REVIVE` |
-| `VICTORYROAD_POKE_BALL3` | `SPRITE_POKE_BALL` | 18 | 29 | `SPRITEMOVEDATA_STILL` | `OBJECTTYPE_ITEMBALL` | `VictoryRoadFullRestore` = `itemball FULL_RESTORE` | `EVENT_VICTORY_ROAD_FULL_RESTORE` |
-| `VICTORYROAD_POKE_BALL4` | `SPRITE_POKE_BALL` | 15 | 48 | `SPRITEMOVEDATA_STILL` | `OBJECTTYPE_ITEMBALL` | `VictoryRoadFullHeal` = `itemball FULL_HEAL` | `EVENT_VICTORY_ROAD_FULL_HEAL` |
-| `VICTORYROAD_POKE_BALL5` | `SPRITE_POKE_BALL` | 7 | 38 | `SPRITEMOVEDATA_STILL` | `OBJECTTYPE_ITEMBALL` | `VictoryRoadXSpecial` = `itemball X_SPECIAL` | `EVENT_VICTORY_ROAD_X_SPECIAL` |
-
-All rows use radius 0,0, hours -1,-1 (always present), palette 0, sight 0.
-
-Object-flag polarity (this bites bot authors): `CheckObjectFlag` in
-`engine/overworld/map_objects_2.asm:32` masks an object when its event flag is
-**set**, and shows it when the flag is clear or is `-1`. `Script_appear` clears
-the flag, `Script_disappear` sets it (`engine/overworld/scripting.asm:879-897`).
-`InitializeEventsScript` in `engine/events/std_scripts.asm:521` sets
-`EVENT_RIVAL_VICTORY_ROAD` at new game, so the rival object starts hidden and is
-only revealed by the `appear` inside the ambush script.
-
-**Derived collision map** (not verbatim asm - built by decoding
-`maps/VictoryRoad.blk` through `data/tilesets/cave_collision.asm` and
-`data/collision/collision_permissions.asm`, with the quadrant index
-`(x & 1) + 2 * (y & 1)` taken from `GetCoordTileCollision` in
-`home/map.asm:2065`). It is included because Victory Road is the one map in this
-section where "which tile can I stand on" is the whole problem.
-
-Verification: all ten `warp_event` tiles land on the expected collision
-(`WARP_CARPET_DOWN`, six `LADDER`, `PIT`, `FLOOR`, `CAVE`) and all six
-`object_event` tiles land on walkable tiles, so the decode is aligned.
-
-Legend: `.` floor, `#` wall (impassable), `^` `COLL_UP_WALL` (walkable, but you
-cannot step *down* into it and cannot step *up* off it), `L` ladder, `P` pit,
-`C` cave exit, `W` warp carpet (needs a DOWN press), `<` `HOP_LEFT`,
-`>` `HOP_RIGHT`, `v` `HOP_DOWN` (all three are walkable land; pressing the
-matching direction while standing on one jumps two tiles - see `.TryJump` and
-`.ledge_table` in `engine/overworld/player_movement.asm:354-391`, which reads the
-tile the player is **standing on**, not the tile ahead).

-One-way transitions a bot must respect (all derived from the grid above):
-
- (0,11) `PIT` -> (0,27). No route back up from (0,27); the return is a ledge.
- (8,28) or (8,29) `HOP_RIGHT` + RIGHT -> (10,28) / (10,29), which reaches the (13,31) ladder. This is the short way out of the TM pocket.
- (2,30) or (3,30) `HOP_DOWN` + DOWN -> (2,32) / (3,32), which drops into the pocket that holds the (1,35) ladder. This is the long way out of the TM pocket.
- (16..19, 34) `HOP_DOWN` + DOWN -> (16..19, 36). This is the only exit from the Full Restore shelf, and it is why the FAQ says "jump down".
- (8,20) or (8,21) `HOP_RIGHT` + RIGHT -> (10,20) / (10,21) in the top region.
- Rows of `^` (`COLL_UP_WALL`) are walkable dead strips: you may enter them from the side or from below and leave sideways or downward, never upward, and you can never step down onto one.

-| `EVENT_RIVAL_VICTORY_ROAD` | `constants/event_flags.asm:1124` | set by `InitializeEventsScript` (`engine/events/std_scripts.asm:521`) and again by `VictoryRoadRivalNext`; cleared by the `appear` in the ambush scripts | set = rival object masked. Postcondition of the ambush. |
-| `EVENT_VICTORY_ROAD_TM_EARTHQUAKE` | `constants/event_flags.asm:1092` | itemball object flag | set once TM26 is taken |
-| `EVENT_VICTORY_ROAD_MAX_REVIVE` | `constants/event_flags.asm:1093` | itemball object flag | set once Max Revive is taken |

-| `EVENT_VICTORY_ROAD_HIDDEN_FULL_HEAL` | `constants/event_flags.asm:169` | `hiddenitem` operand at bg (3,65) | set once dug up |
-| `EVENT_GOT_TOTODILE_FROM_ELM` (`:37`), `EVENT_GOT_CHIKORITA_FROM_ELM` (`:38`) | `constants/event_flags.asm` | read by `VictoryRoadRivalNext` | selects which of the three rival parties loads. `EVENT_GOT_CYNDAQUIL_FROM_ELM` (`:36`) is never read here; Cyndaquil is the fall-through case |
-| `SCENE_VICTORYROAD_RIVAL_BATTLE` = 0 | defined inline by the `scene_script` macro (`macros/scripts/maps.asm:25`, `const_def` starting at 0) via `maps/VictoryRoad.asm:11` | compared by both coord events | the scene the map starts a new game on |
-| `SCENE_VICTORYROAD_NOOP` = 1 | same, `maps/VictoryRoad.asm:12` | written by `setscene` at the end of both ambush scripts | rival ambush disarmed |
-
-Both scene scripts (`VictoryRoadNoop1Scene`, `VictoryRoadNoop2Scene`) are a bare
-`end`; the scene id only gates the coord events.
-
-**Items**
-
-| item | how obtained | source (label / bg_event / hidden) | one-time flag |

-**Wild encounters**
-
-`data/wild/kanto_grass.asm:144` `def_grass_wildmons VICTORY_ROAD` (Victory Road
-lives in the Kanto grass table even though it is Johto-side).
-
-Encounter rates: `db 6 percent, 6 percent, 6 percent` (morn / day / nite - all
-equal). Slot weights come from `GrassMonProbTable`
-(`data/wild/probabilities.asm:6`): 30 / 30 / 20 / 10 / 5 / 4 / 1 percent.
-
-Gold (`IF DEF(_GOLD)`), identical for morn, day and nite:

-
-Silver (`ELIF DEF(_SILVER)`) is the same table with slot 3 replaced by
-`db 33, DONPHAN`.
-
-No water, fishing, headbutt or rock-smash data: there is no `VICTORY_ROAD` row in
-`data/wild/kanto_water.asm`, `data/wild/johto_water.asm`, `data/wild/fish.asm` or
-`data/wild/treemons.asm`, and the decoded collision map contains no water tiles.
-The `FISHGROUP_SHORE` in the header is therefore unreachable. No roamer either
-(`VICTORY_ROAD` is absent from `data/wild/roammon_maps.asm`).

-Row 11 is walkable only at x=8 (where the officer stands) and x=10, so
-**(10,11) is a mandatory chokepoint**: the badge check cannot be walked around.
-
-**Scripts of interest**
-
- `_VictoryRoadGateBadgeCheckScript` (`maps/VictoryRoadGate.asm:25`, sym `5f:4fe3`):
-  `writetext VictoryRoadGateOfficerText`, `promptbutton`, `readvar VAR_BADGES`,
-  `ifgreater NUM_JOHTO_BADGES - 1, .AllEightBadges`. On failure it prints
-  `VictoryRoadGateNotEnoughBadgesText` and `applymovement PLAYER,
-  VictoryRoadGateStepDownMovement` (one `step DOWN`, pushing the player back
-  south). On success it prints `VictoryRoadGateEightBadgesText` and
-  `setscene SCENE_VICTORYROADGATE_NOOP`, permanently disarming the coord event.
- `VictoryRoadGateOfficerScript` (`maps/VictoryRoadGate.asm:23`) - `faceplayer`
-  then the same body, so talking to the officer also opens the gate.
-
-## 3. Blockers and gates
-
-| Gate | Enforced by (file:label) | Requirement | Unlock condition |
-|---|---|---|---|
-| Entry to Victory Road | `maps/VictoryRoadGate.asm:19` `VictoryRoadGateBadgeCheckScript` / `_VictoryRoadGateBadgeCheckScript` | `readvar VAR_BADGES` then `ifgreater NUM_JOHTO_BADGES - 1` (that is, badge count must be >= 8). `NUM_JOHTO_BADGES` = 8 (`constants/ram_constants.asm:260`). `VAR_BADGES` resolves to `.CountBadges` in `engine/overworld/variables.asm:80`, which is `CountSetBits` over **two** bytes (`wBadges`, b = 2), i.e. Johto **and** Kanto badges together | own all eight Johto badges. The script then sets `SCENE_VICTORYROADGATE_NOOP`, so the check runs at most once |
-| Physical block west to Route 28 | `maps/VictoryRoadGate.asm:118` object `VICTORYROADGATE_BLACK_BELT1` at (7,5), masked when `EVENT_OPENED_MT_SILVER` is set | row 5 is the only east-west corridor in the gate and he stands in it | out of scope here (Mt. Silver, later section) |
-| Physical block east to Route 22 | `maps/VictoryRoadGate.asm:119` object `VICTORYROADGATE_BLACK_BELT2` at (12,5), masked when `EVENT_FOUGHT_SNORLAX` is set | same corridor | out of scope here (Kanto, later section) |
-| Rival ambush before the exit | `maps/VictoryRoad.asm:255-256` coord events at (12,8) and (13,8), gated on `SCENE_VICTORYROAD_RIVAL_BATTLE` | those two tiles are the whole corridor to the exit at (13,5) | win the battle; the script then runs `setscene SCENE_VICTORYROAD_NOOP` |
-| TM26 Earthquake | geometry only, no flag: (3,28) is inside the y=26..30 pocket whose only entrance is the `COLL_PIT` at (0,11) | reach the top region first (so: beat the ladders, not the rival) | none |
-| Full Restore | geometry only: (18,29) is on a shelf whose only entrance is warp 7 (17,19) -> (17,33) | reach the top region | none |
-
-Field moves: **none required**. There is no `COLL_CUT_TREE`, no water, no
-strength boulder and no whirlpool anywhere in the decoded map, and the header
-palette is `PALETTE_NITE`, not `PALETTE_DARK`, so **Flash is not needed** either.
-The FAQ's "no puzzles to solve now" is accurate.
-
-## 4. Bot checklist
-
-Coordinates are map cells `(x, y)` on the named map. "step" means walk onto the
-tile; ladders and the pit fire on arrival (`Permissions.isImmediateWarp`
-equivalent: `COLL_LADDER` = `$72` and `COLL_PIT` = `$60` are warp collisions),
-while the entrance carpet at (9,67) fires on a DOWN press.
-
-1. `MAP_VICTORY_ROAD_GATE`: from the Route 26 door at (9,17)/(10,17) walk north along x=10. Precondition: 8 Johto badges. Step (10,11) -> `VictoryRoadGateBadgeCheckScript` fires. Postcondition: `wVictoryRoadGateSceneID` = `SCENE_VICTORYROADGATE_NOOP`. If badges < 8 the script pushes you one step DOWN and you cannot pass.
-2. `MAP_VICTORY_ROAD_GATE`: step (9,0) or (10,0) -> warp to `MAP_VICTORY_ROAD` (9,67).
-3. `MAP_VICTORY_ROAD` entrance region. Waypoints that were checked against the
-   collision map: (9,66) -> west along y=66 to (7,66) -> north x=7 through
-   y=65,64 to (7,63) -> (7,62) -> east along y=62 to (11,62)/(12,62) -> north
-   x=11/12 through y=61..55 -> (11,54) -> the long y=53/54 corridor (x=5..16).
-4. Max Revive and Full Heal: from the y=53/54 corridor go east to (15,54) ->
-   (15,55) -> (15,56) -> east along y=56 to (18,56) -> north along x=18 through
-   y=55,54,53,52 to (18,51) -> west along y=51 to (15,51) -> (15,50) -> (16,50)
-   -> (16,49) -> (16,48), press A facing LEFT
-   into (15,48) -> Full Heal (`EVENT_VICTORY_ROAD_FULL_HEAL`). Then west along
-   y=50 to (12,50) -> (12,49) -> press A facing UP into (12,48) -> Max Revive
-   (`EVENT_VICTORY_ROAD_MAX_REVIVE`).
-5. Optional hidden Full Heal: face the wall at (3,65) from (2,65), (4,65),
-   (3,64) or (3,66) and press A. Postcondition
-   `EVENT_VICTORY_ROAD_HIDDEN_FULL_HEAL`.
-6. Back along the y=53/54 corridor to its west end, (3,53) -> (2,52) -> (2,51)
-   -> (2,50) -> (1,49); the ladder fires on arrival -> warp 2 -> (1,35).
-7. X Special. Verified chain from the ladder landing: (1,35) -> (1,36) -> (1,37)
-   -> (1,38) -> east along y=38 to (5,38) -> (5,37) -> (5,36) -> east along y=36
-   to (9,36)/(10,36) -> (9,37)/(10,37) -> (9,38)/(10,38) -> south through
-   y=39,40 (x=9..16 is open) -> (13,41) -> (13,42) -> west along y=42 to (7,42)
-   -> north along x=7 (the `HOP_LEFT` column is walkable) through y=41,40,39 to
-   (7,38). Press A -> X Special. Postcondition `EVENT_VICTORY_ROAD_X_SPECIAL`.
-   Do **not** press LEFT while on that column (it triggers a two-tile jump into
-   a wall column).
-8. To the (13,31) ladder: back to (7,42) -> east along y=42 to (18,42) -> north
-   along x=18 through y=41,40,39,38 to (18,37) -> west along y=37 then y=36 to
-   (13,36) -> north (13,35), (13,34), (13,33), (13,32) -> step (13,31) -> warp 4
-   -> arrive (13,17). Note you cannot climb x=13 straight up from y=41: (13,38)
-   is `COLL_UP_WALL` and blocks the step up out of it, and the x=11 column walls
-   off the y=34..36 strip on its west side.
-9. Optional Full Restore detour. The verified chain from the ladder to (17,19) is:
-   (13,17) -> (13,16) -> east along y=16 to (16,16) -> (16,15) -> (16,14) ->
-   west along y=14 to (9,14)/(10,14) -> south x=9/10 through y=15,16,17 to
-   (9,18)/(10,18) -> west along y=18 to (5,18) -> (5,17) -> (5,16) -> west along
-   y=16 to (3,16) -> (3,17) -> (3,18) -> (3,19) -> (3,20) -> east along y=20 to
-   (8,20) -> **press RIGHT to hop the ledge**, landing (10,20) -> east/north to
-   (16,19) -> (17,19). On the cart that `HOP_RIGHT` is the only way into the
-   (17,19) pocket. Step (17,19) -> warp 7 -> arrive (17,33). Walk north along
-   x=17..19 to (18,29), press A -> Full Restore. Postcondition
-   `EVENT_VICTORY_ROAD_FULL_RESTORE`. Return to y=34 (x=16..19) and press DOWN to
-   hop the ledge, landing on y=36 - which is already the y=36 corridor, so go
-   west to (13,36) and north to (13,31), warp 4, back to (13,17).
-10. From (13,17): (13,16) -> east along y=16 to (18,16) -> north along x=18
-    through (18,15), (18,14), (18,13) (the rival's masked object tile), (18,12)
-    to (18,11) -> west along y=11 to (13,11) -> north (13,10), (13,9) to (13,8).
-11. Step (12,8) or (13,8) -> rival ambush. Precondition `wVictoryRoadSceneID` = 0. Battle `RIVAL1` member 13/14/15 depending on the starter events. Postconditions: `EVENT_RIVAL_VICTORY_ROAD` set, `wVictoryRoadSceneID` = `SCENE_VICTORYROAD_NOOP`.
-12. TM26 detour. The x=6,7 wall pair on y=10 and the x=5..8 wall run on y=11 mean
-    you cannot walk straight west; the verified chain is (9,11) -> (9,10) ->
-    (8,10) -> (8,9) -> west along y=9 to (5,9) -> (5,10) -> west along y=10 to
-    (0,10) -> (0,11), the `COLL_PIT`, which fires on arrival -> land at (0,27).
-    Then (0,28) -> east along y=28 to (2,28), press A facing RIGHT into the ball
-    object at (3,28) -> TM26 Earthquake (`EVENT_VICTORY_ROAD_TM_EARTHQUAKE`).
-    Optionally step to (2,29) and press A facing RIGHT into the wall at (3,29)
-    -> hidden Max Potion (`EVENT_VICTORY_ROAD_HIDDEN_MAX_POTION`).
-13. Leave the pocket: east along y=28 to (7,28) -> step onto (8,28), the
-    `HOP_RIGHT` tile -> press RIGHT to hop to (10,28) -> (10,29) -> east to
-    (12,29) -> (12,30) -> (12,31) -> step (13,31) -> warp 4 -> (13,17).
-    (Alternative, longer: stand on (2,30) or (3,30) and press DOWN, landing at
-    y=32, which drops you back in the (1,35) ladder pocket and forces a full
-    re-cross of the middle region via steps 7 and 8.)
-14. Repeat step 10 to return to the exit corridor. The coord events no longer fire.
-15. Walk (13,7) -> (13,6) -> step (13,5) (`COLL_CAVE`) -> warp 10 -> `MAP_ROUTE_23` (9,13). End of section.

-## 5. Port coverage
-
-| Beat | Port file | Status |
-|---|---|---|
-| Map header, dimensions, warps, coord events, bg events, object events for any Gold map | `src/import/RomExtractorGen2.lua` (map event reader at lines 785-865, `extractMaps` from 866) | implemented - data driven off the ROM, so `VICTORY_ROAD` needs no hand port |
-| `OBJECTTYPE_ITEMBALL` item data extraction | `src/import/RomExtractorGen2.lua:2968` (`obj.itemball = readItemBall(...)`) | implemented (extraction only) |
-| **Picking up a Poke Ball object** (all five Victory Road items) | `src/world/gen2/World.lua:5257` `World:interact` | **missing** - the A-press path handles trainers, strength boulders, `scriptKey` NPCs, `BGEVENT_READ` signs, `BGEVENT_ITEM` hidden items and the tile-collision field moves. Nothing consumes `obj.itemball`, and an itemball object has no `scriptKey`, so the press falls through |
-| Hidden items (`BGEVENT_ITEM`, the two here) | `src/world/gen2/HiddenItems.lua`, used at `src/world/gen2/World.lua:5290` | implemented |
-| Ladder / cave / pit warps | `src/world/gen2/Permissions.lua:162` `isWarpCollision` (covers `$60` PIT and the `$7x` block) and `isImmediateWarp` | implemented - the (0,11) hole and all six ladders work |
-| Warp carpet needing a direction press (the (9,67) entrance) | `src/world/gen2/Permissions.lua:170` `CARPET_DIR` | implemented |
-| Walkability from `CollisionPermissionTable` | `src/world/gen2/Permissions.lua:11` (256-entry table), `src/world/gen2/Map.lua:59` | implemented |
-| **Ledge hops** (`COLL_HOP_LEFT/RIGHT/DOWN`, five of them in this map) | - | **missing** - no `$a0..$a7` handling anywhere under `src/world/gen2/`. The tiles are LAND in the port's permission table, so a bot can walk over them freely. Net effect: the one-way ledges become two-way, and the Full Restore shelf / TM pocket exits behave differently from the cart |
-| **Directional side walls** (`COLL_UP_WALL`, heavily used here) | `src/world/gen2/FieldMoves.lua:313` `BLOCKED_BY` | partial - the `$b0..$b7` table exists but is only consulted by `FieldMoves.directionBlocked` for surf/field-move refusals. There is no port equivalent of `GetMovementPermissions` (`home/map.asm:1868`), so `UP_WALL` does not restrict ordinary walking |
-| Coord events gated on the map scene | `src/world/gen2/World.lua:5007` `World:tryCoordScript`, scene storage at `World.lua:740` / `World:scene` at 1161 | implemented |
-| Scene scripts / `setscene` persistence across save | `src/world/gen2/World.lua:558-584`, `src/core/gen2/Save.lua` | implemented |
-| Rival ambush opcodes (`moveobject`, `turnobject`, `showemote`, `appear`, `disappear`, `applymovement`, `scall`, `setscene`, `playmapmusic`, `playmusic`, `winlosstext`, `setlasttalked`, `loadtrainer`, `startbattle`, `dontrestartmapmusic`, `reloadmapafterbattle`) | `src/script/gen2/Opcodes.lua` (table), `src/script/gen2/Vm.lua` (`moveobject` 337, `showemote` 961, `loadtrainer` 806, `winlosstext` 918, `reloadmapafterbattle` 886) | implemented |
-| `special FadeOutMusic` | `src/script/gen2/Specials.lua:1066` | implemented |
-| `VAR_BADGES` (the gate check) | `src/world/gen2/World.lua:1240` - counts `player.badges` + `player.kantoBadges`, matching `CountSetBits` over two bytes | implemented |
-| Object masking by event flag | `src/import/RomExtractorGen2.lua` object `eventFlag` field; `src/world/gen2/Npc.lua` | partial - the flag is extracted, but confirm the mask polarity (hidden when **set**) matches `CheckObjectFlag`; not verified in this pass |
-| Wild encounters for this map | `src/import/RomExtractorGen2.lua:3720` (`JohtoGrassWildMons` / `KantoGrassWildMons`), `src/battle/gen2/Encounter.lua` | implemented |
-| Battle music landmark split | `src/battle/gen2/BattleMusic.lua:45-56` explicitly names the Victory Road landmark boundary | implemented |
-| A driver that walks Victory Road | - | **missing** - no `tests/drivers/gold_*.lua` mentions Victory Road |
-
-## 6. Unresolved / verify by hand
-
- **Rival Magneton level.** The FAQ says "Level 34 Magneton". The asm has 35 in
-  RIVAL1 (13) and RIVAL1 (14) and 34 only in RIVAL1 (15), the Feraligatr set
-  loaded when the player picked Cyndaquil. The FAQ appears to have been written
-  from one playthrough.
- **Rival party order.** The FAQ lists the starter evolution fourth. The asm
-  order is Sneasel, Golbat, Magneton, Haunter, Kadabra, starter (starter last).
- **"You get: 2280G"** and the per-mon EXP figures were not verified; base money
-  for the `RIVAL1` class lives in the trainer class attribute table, which was
-  not opened for this pass.
- **Wild list.** The FAQ lists only Golbat, Graveler, Rhyhorn and "Donphan
-  (Silver only)". The asm table also carries Onix (two slots, L34 and L36) and,
-  in Gold, Ursaring at L33 in the slot Silver gives to Donphan.
- **Item list.** The FAQ's item list omits the hidden Max Potion at (3,29) and
-  does not distinguish the itemball Full Heal at (15,48) from the hidden Full
-  Heal at (3,65).
- **"Head up the stairway"** - there is no `COLL_STAIRCASE` in the decoded
-  Victory Road map. What the FAQ calls stairways and cliffs are ordinary floor
-  plus the `COLL_UP_WALL` strips; the only vertical transitions are the six
-  ladders, the pit and the five ledges.
- **"Head back up the ladder to get back to the third floor"** (after TM26).
-  There is no ladder inside the TM pocket. The two ways out are the `HOP_RIGHT`
-  at (8,28)/(8,29) into the x=10..13 corridor that reaches the (13,31) ladder,
-  and the `HOP_DOWN` at (2,30)/(3,30) into the (1,35) pocket. The checklist above
-  prefers the first; which one the FAQ author meant is not recoverable from the
-  text.
- **X Special tile.** The Poke Ball at (7,38) sits on a `COLL_HOP_LEFT` tile with
-  `COLL_WALL` on both sides and above. Ledge tiles are `LAND_TILE` in
-  `CollisionPermissionTable`, so the column x=7, y=38..41 is walkable from
-  (7,42) upward and the ball is reachable; but this should be confirmed on
-  hardware or in an emulator, because it is the one placement in this map that
-  looks like a mistake rather than a design.
- **The gate's black belts as physical blockers.** The claim that
-  `VICTORYROADGATE_BLACK_BELT1` at (7,5) and `BLACK_BELT2` at (12,5) block the
-  only east-west corridor is inferred from the decoded gate collision (row 5 is
-  the sole corridor and rows 4/6 are walls beside it) plus the fact that NPCs are
-  solid. It is not stated in any script, and it belongs to later sections
-  (Route 28 / Route 22) rather than this one.
- **Object flag polarity in the port** was not tested; see the Port coverage row.

-Note the last row: the "Abra" the walkthrough names is declared with
-`SPRITE_JYNX` (`constants/sprite_constants.asm:122`; `data/sprites/sprite_mons.asm`
-maps that slot to `JYNX`). Its script is `AbraScript`, which does
-`cry ABRA`. Verbatim from the file, not a typo of mine.
-
-An object's event flag hides it when the flag is **set** (`Script_disappear`
-sets, `Script_appear` clears - `engine/overworld/scripting.asm:879-898`).
-`EVENT_INDIGO_PLATEAU_POKECENTER_RIVAL` is set on New Game by
-`engine/events/std_scripts.asm:556` (the `EVENT_INITIALIZED_EVENTS` block), so
-the rival starts hidden. `EVENT_TELEPORT_GUY` is not in that block, so the old
-man and his Pokémon are visible from the first visit.
-
-**Scripts of interest**
-
- `IndigoPlateauPokecenter1FPrepareElite4Callback` (`5a:48b6`), a
-  `callback MAPCALLBACK_NEWMAP`. **This is the single most important script in
-  the section for a bot**: every time you set foot in the lobby it resets the
-  whole Elite Four run.
-
-  ```
-  setmapscene WILLS_ROOM,   SCENE_WILLSROOM_LOCK_DOOR
-  setmapscene KOGAS_ROOM,   SCENE_KOGASROOM_LOCK_DOOR
-  setmapscene BRUNOS_ROOM,  SCENE_BRUNOSROOM_LOCK_DOOR

-  clearevent EVENT_BEAT_CHAMPION_LANCE
-  setevent   EVENT_LANCES_ROOM_OAK_AND_MARY   ; hide Oak + Mary again
-  endcallback
-  ```
-
-  Consequences: the five `EVENT_BEAT_ELITE_4_*` flags are **not** durable
-  progress markers - they only survive within one uninterrupted run. The durable
-  "I beat the League" flag is `EVENT_BEAT_ELITE_FOUR`, set in `HallOfFameEnterScript`.
- `PlateauRivalBattle1` / `PlateauRivalBattle2` -> `PlateauRivalBattleCommon`.
-  Guards, in order:
-  1. `checkevent EVENT_BEAT_RIVAL_IN_MT_MOON` / `iffalse` -> done (so this only
-     ever fires post-game, after the Mt. Moon rematch),
-  2. `checkflag ENGINE_INDIGO_PLATEAU_RIVAL_FIGHT` / `iftrue` -> done (once a day),
-  3. `readvar VAR_WEEKDAY` with `ifequal SUNDAY / TUESDAY / THURSDAY / FRIDAY /
-     SATURDAY` -> done. **Only Monday and Wednesday.**
-
-  Then `moveobject`/`appear` the rival, `showemote EMOTE_SHOCK`,
-  `special FadeOutMusic`, a 5-step `applymovement`, `playmusic MUSIC_RIVAL_ENCOUNTER`,
-  `setevent EVENT_INDIGO_PLATEAU_POKECENTER_RIVAL`, then a starter-dependent
-  `loadtrainer RIVAL2, RIVAL2_2_*` + `startbattle`. Afterwards
-  `PlateauRivalPostBattle` plays `MUSIC_RIVAL_AFTER`, walks him off with
-  `disappear`, and `setflag ENGINE_INDIGO_PLATEAU_RIVAL_FIGHT`.
- `IndigoPlateauPokecenter1FNurseScript` -> `jumpstd PokecenterNurseScript` (free heal).
- `IndigoPlateauPokecenter1FClerkScript` -> `pokemart MARTTYPE_STANDARD, MART_INDIGO_PLATEAU`.
- `TeleportGuyScript` (`5a:49e5`): `yesorno`; on yes, `playsound SFX_WARP_TO`,
-  `special FadeOutToWhite`, `warp NEW_BARK_TOWN, 13, 6`. The walkthrough's "Abra
-  will teleport you back" lands you in **New Bark Town**, specifically, not
-  "back to Johto" generically.
- `AbraScript`: text + `cry ABRA`, nothing else.
-
-**Flags and events**
-
-| constant | defined in | read/written by | meaning for a bot |
-|---|---|---|---|
-| `EVENT_INDIGO_PLATEAU_POKECENTER_RIVAL` | `constants/event_flags.asm:1309` | set by `std_scripts.asm:556` on New Game and by `PlateauRivalBattleCommon`; cleared by `appear` | hides the rival object |
-| `EVENT_TELEPORT_GUY` | `constants/event_flags.asm:1310` | set by `HallOfFameEnterScript` | after the Hall of Fame the old man **and** his Pokémon vanish; the ride home is a pre-champion service only |
-| `EVENT_BEAT_RIVAL_IN_MT_MOON` | `constants/event_flags.asm:456` | read by both `PlateauRivalBattle*` | precondition for the lobby ambush |
-| `ENGINE_INDIGO_PLATEAU_RIVAL_FIGHT` | `constants/engine_flags.asm:111` (in the `wDailyFlags2` block) | read/set by `PlateauRivalBattle*` | daily one-shot; cleared with the rest of the daily flags at midnight |
-| `SCENE_INDIGOPLATEAUPOKECENTER1F_RIVAL_BATTLE` | the map's own `def_scene_scripts` (value 0) | coord events | see the quirk note below |
-
-Scene quirk worth knowing: this map declares exactly one scene script, so
-`SCENE_INDIGOPLATEAUPOKECENTER1F_RIVAL_BATTLE == 0`, which is also the default
-value of `wMapScenes` for the map. `PlateauRivalPostBattle`'s
-`setscene SCENE_INDIGOPLATEAUPOKECENTER1F_RIVAL_BATTLE` therefore writes 0 over
-0 and the two coord events stay armed forever. The real one-shot guards are
-`ENGINE_INDIGO_PLATEAU_RIVAL_FIGHT` and the weekday check.
-
-**Items**
-
-| item | how obtained | source (label / bg_event / hidden) | one-time flag |
-|---|---|---|---|
-| `ULTRA_BALL`, `MAX_REPEL`, `HYPER_POTION`, `MAX_POTION`, `FULL_RESTORE`, `REVIVE`, `FULL_HEAL` | bought | `MartIndigoPlateau` (`data/items/marts.asm:384`, symbol `05:645a`), opened by `IndigoPlateauPokecenter1FClerkScript` | n/a |
-
-This is where the walkthrough's "ten Hyper Potions, ten Revives, ten Full Heals"
-shopping list is actually satisfiable - the mart carries all three plus Full
-Restore.

-**Trainers**
-
-| const | class | id | party (`data/trainers/parties.asm` label) | script label | rematch/phone |
-|---|---|---|---|---|---|

Moon |
-
-`Rival2Group` (4)-(6), all `TRAINERTYPE_MOVES`:
-`45 SNEASEL`, `48 CROBAT`, `45 MAGNETON`, `46 GENGAR`, `46 ALAKAZAM`, and then
-`50 MEGANIUM` / `50 TYPHLOSION` / `50 FERALIGATR` respectively. The walkthrough
-does not mention this fight at all - a bot that walks the lobby on a Monday
-will hit it whether or not it planned to.
-
-**Wild encounters** - none (indoor).

-
-**Scripts of interest**
-
- `WillsRoomDoorLocksBehindYouScript` (`5a:4d8c`), deferred by the scene script:
-  `applymovement PLAYER, WillsRoom_EnterMovement` (4 x `step UP`, so you enter at
-  `(5, 17)` and end at `(5, 13)`), `reanchormap $85`, `playsound SFX_STRENGTH`,
-  `earthquake 80`, `changeblock 4, 14, $2a` (wall), `refreshmap`,
-  `setscene SCENE_WILLSROOM_NOOP`, `setevent EVENT_WILLS_ROOM_ENTRANCE_CLOSED`.
-  `changeblock` operands are in the same tile space as warps but are halved
-  internally (`Script_changeblock` adds 4 then `GetBlockLocation` shifts right,
-  `home/map.asm:2099`), so `4, 14` is the block covering tiles `(4..5, 14..15)` -
-  the corridor square immediately below where the walk-in leaves you. That is
-  what makes the walkthrough's "You can't go back to the Pokémon Center to heal
-  between battles" literally true.
- `WillsRoomDoorsCallback`, `callback MAPCALLBACK_TILES`: re-applies
-  `changeblock 4, 14, $2a` while `EVENT_WILLS_ROOM_ENTRANCE_CLOSED` is set and
-  `changeblock 4, 2, $16` (open door) while `EVENT_WILLS_ROOM_EXIT_OPEN` is set,
-  so the room's geometry survives a battle reload.
- `WillScript_Battle` (`5a:4da4`): `faceplayer`, `opentext`,
-  `checkevent EVENT_BEAT_ELITE_4_WILL` / `iftrue WillScript_AfterBattle`,
-  `writetext WillScript_WillBeforeText`, `winlosstext WillScript_WillBeatenText, 0`,

-  `changeblock 4, 2, $16` (open the north door), `refreshmap`,
-  `setevent EVENT_WILLS_ROOM_EXIT_OPEN`.
-
-  Note there is **no `winlosstext` loss branch** (the second operand is `0`) and
-  no `BATTLETYPE_CANLOSE`: losing to any Elite Four member is an ordinary
-  blackout, which is why the FAQ says "If you lose, you have to start all over".

-## 3. Blockers and gates
-
-| Gate | Enforced by (file:label) | Requirement | Unlock condition |
-|---|---|---|---|
-| Entry to Victory Road (and therefore to this whole section) | `maps/VictoryRoadGate.asm:_VictoryRoadGateBadgeCheckScript` - `readvar VAR_BADGES` / `ifgreater NUM_JOHTO_BADGES - 1, .AllEightBadges` | all 8 Johto badges | `.AllEightBadges` does `setscene SCENE_VICTORYROADGATE_NOOP`; otherwise you get `applymovement PLAYER, VictoryRoadGateStepDownMovement` and are pushed back. **This gate belongs to the previous section**, listed here only because it is the precondition for everything below |
-| Fly to Indigo Plateau | `maps/Route23.asm:Route23FlypointCallback` | one `MAPCALLBACK_NEWMAP` on Route 23 | `setflag ENGINE_FLYPOINT_INDIGO_PLATEAU` |
-| No retreat once inside an Elite Four room | `maps/WillsRoom.asm:WillsRoomDoorLocksBehindYouScript` (and the Koga/Bruno/Karen/Lance twins) - `changeblock 4, 14, $2a` (Lance: `changeblock 4, 22, $34`) plus `EVENT_*_ROOM_ENTRANCE_CLOSED` re-applied by each map's `MAPCALLBACK_TILES` | none - it is unconditional on entry | never, within a run. The lobby's `MAPCALLBACK_NEWMAP` clears the flags, but you can only reach the lobby by finishing or blacking out |
-| Each room's north door | `WillScript_Battle` / `KogaScript_Battle` / `BrunoScript_Battle` / `KarenScript_Battle` - `changeblock 4, 2, $16` + `setevent EVENT_*_ROOM_EXIT_OPEN`, replayed by the map's `MAPCALLBACK_TILES` | beat that member | door block becomes `$16` (open) and warps at `(4, 2)`/`(5, 2)` become reachable |
-| Lance's north door | `maps/LancesRoom.asm:LancesRoomLanceScript` - `changeblock 4, 0, $0b` | beat Lance | opened, but the script warps you through immediately anyway |
-| Approaching Lance at all | `def_coord_events` at `(4, 5)` / `(5, 5)` gated on `SCENE_LANCESROOM_APPROACH_LANCE` | that scene is only set at the end of `LancesRoomDoorLocksBehindYouScript` | walking in through warp 1/2 always sets it; a bot teleported straight to y < 5 would skip the fight |
-| Lobby rival ambush | `maps/IndigoPlateauPokecenter1F.asm:PlateauRivalBattle1/2` | `EVENT_BEAT_RIVAL_IN_MT_MOON` set, `ENGINE_INDIGO_PLATEAU_RIVAL_FIGHT` clear, `VAR_WEEKDAY` in {MONDAY, WEDNESDAY} | not a progress gate - a hazard. Avoid tiles `(16, 4)` / `(17, 4)` if the run cannot afford a level-45-50 six-mon fight |
-| No HM field move is required anywhere in this section | grep: no `Route23`/Elite Four map references any `engine/overworld/` field-move script; the walkthrough's "you do NOT need to have every HM" is correct | - | - |

-Coordinates are the raw asm map coordinates (tile grid, origin top-left, before

-
-| # | Map | Target | Intent | Precondition | Postcondition |
-|---|---|---|---|---|---|
-| 1 | `VICTORY_ROAD` | warp at `(13, 5)` | walk onto warp | 8 Johto badges (already spent at `VictoryRoadGate`) | on `ROUTE_23` at warp 3 `(9, 13)` |
-| 2 | `ROUTE_23` | any tile (map load) | step | - | `ENGINE_FLYPOINT_INDIGO_PLATEAU` set |
-| 3 | `ROUTE_23` | `(9, 5)` or `(10, 5)` | walk onto warp | - | in `INDIGO_PLATEAU_POKECENTER_1F` at `(5, 13)`/`(6, 13)`; the `MAPCALLBACK_NEWMAP` resets all Elite Four scenes/flags |
-| 4 | `INDIGO_PLATEAU_POKECENTER_1F` | `INDIGOPLATEAUPOKECENTER1F_NURSE` at `(3, 7)` | talk (A, facing up from `(3, 8)`) | - | party healed (`jumpstd PokecenterNurseScript`) |
-| 5 | `INDIGO_PLATEAU_POKECENTER_1F` | `INDIGOPLATEAUPOKECENTER1F_CLERK` at `(11, 7)` | talk, buy | money | stock Hyper Potion / Full Heal / Revive / Full Restore from `MartIndigoPlateau` |
-| 6 | `INDIGO_PLATEAU_POKECENTER_1F` | avoid `(16, 4)` and `(17, 4)` | pathing constraint | only matters if `EVENT_BEAT_RIVAL_IN_MT_MOON` is set and today is Mon/Wed | skipping avoids `RIVAL2_2_*` |
-| 7 | `INDIGO_PLATEAU_POKECENTER_1F` | warp at `(14, 3)` | walk onto warp | - | in `WILLS_ROOM` at `(5, 17)`; scene 0 fires `WillsRoomDoorLocksBehindYouScript` |
-| 8 | `WILLS_ROOM` | (automatic) | wait out `applymovement` | - | player at `(5, 13)`, `EVENT_WILLS_ROOM_ENTRANCE_CLOSED` set, scene = 1 |
-| 9 | `WILLS_ROOM` | `WILLSROOM_WILL` at `(5, 7)` | walk to `(5, 8)`, face up, A | - | win -> `EVENT_BEAT_ELITE_4_WILL`, `EVENT_WILLS_ROOM_EXIT_OPEN` |
-| 10 | `WILLS_ROOM` | `(4, 2)` or `(5, 2)` | walk onto warp | `EVENT_WILLS_ROOM_EXIT_OPEN` | in `KOGAS_ROOM` at `(4, 17)`/`(5, 17)` |
-| 11 | `KOGAS_ROOM` | `KOGASROOM_KOGA` at `(5, 7)` | walk to `(5, 8)`, face up, A | door-lock cutscene done (player at `(4|5, 13)`) | `EVENT_BEAT_ELITE_4_KOGA`, `EVENT_KOGAS_ROOM_EXIT_OPEN` |
-| 12 | `KOGAS_ROOM` | `(4, 2)` / `(5, 2)` | walk onto warp | exit open | in `BRUNOS_ROOM` at `(4, 17)`/`(5, 17)` |

-Bot notes:
-
- Do **not** re-enter `INDIGO_PLATEAU_POKECENTER_1F` mid-run to heal. You cannot
-  (the doors are sealed), and if some other path got you there, its
-  `MAPCALLBACK_NEWMAP` wipes `EVENT_BEAT_ELITE_4_*` and re-arms all five
-  door-lock scenes, restarting the gauntlet from Will.
- Every fight uses `winlosstext <win>, 0` - no loss branch, no
-  `BATTLETYPE_CANLOSE` - so a loss is a full blackout to the last Pokémon Center.
- After each `startbattle` the scripts run `reloadmapafterbattle`, which re-runs
-  the map's `MAPCALLBACK_TILES` and therefore restores both the sealed south door
-  and (once its flag is set) the opened north door.

-## 5. Port coverage
-
-| Beat | Port file | Status |
-|---|---|---|
-| Map/warp/coord/object tables for all 8 maps | extracted generically by `src/import/RomExtractorGen2.lua` into the Gold cache and read by `src/world/gen2/World.lua` + `src/world/gen2/Map.lua` | implemented (data-driven; nothing map-specific is hand-written) |
-| `MAPCALLBACK_NEWMAP` / `MAPCALLBACK_TILES` dispatch (the lobby reset, the door callbacks) | `src/world/gen2/World.lua`, asserted end-to-end by `tests/drivers/gold_map_callbacks.lua` | implemented |
-| `changeblock` / `refreshmap` door swaps | `src/world/gen2/World.lua:1454` (`World:changeBlock`), `src/script/gen2/Opcodes.lua` | implemented |
-| `reanchormap` | `src/script/gen2/Vm.lua:166` - grouped with `opentext`/`closetext` as a no-op | partial (the camera re-anchor the cart does after the wall drops is not reproduced; cosmetic, but the seal-in frame may differ) |
-| `earthquake 80` shake | `src/script/gen2/Vm.lua:1044` -> `earthquakeFn`, `World:earthquake` (`src/world/gen2/World.lua:1537`) | implemented |
-| Scene scripts / `sdefer` (all five door locks, the Hall of Fame induction) | `src/script/gen2/Vm.lua:92` - `sdefer` is executed **immediately** rather than deferred until the map settles | partial (ordering deviation, called out in the source comment) |
-| `setmapscene` / `setscene` | `src/script/gen2/Opcodes.lua`, `World:mapSceneOf` (`src/world/gen2/World.lua:1179`) | implemented |
-| `loadtrainer` / `startbattle` / `winlosstext` / `reloadmapafterbattle` | `src/script/gen2/Vm.lua`, `src/battle/gen2/Battle.lua`, `src/world/gen2/Trainers.lua` | implemented |
-| Trainer party data (`WillGroup` … `ChampionGroup`), class DVs, class items | extracted by `src/import/RomExtractorGen2.lua` (`TrainerGroups`, ~line 3871) | implemented (data-driven) |
-| AI item use (Koga/Lance Full Restore, Will/Bruno Max Potion, Karen Full Heal) | `src/battle/gen2/Ai.lua:1369-1375`, `src/battle/gen2/Battle.lua:1747` | implemented |
-| Prize money `base x last level` | `src/battle/gen2/Prize.lua` (`Prize.rewardLevel`), used at `src/battle/gen2/Battle.lua:1438` | implemented |
-| `pokemart MARTTYPE_STANDARD, MART_INDIGO_PLATEAU` | `src/script/gen2/Vm.lua:597`, `src/ui/gen2/MartMenu.lua`, mart tables extracted at `src/import/RomExtractorGen2.lua:2582` | implemented |
-| `jumpstd PokecenterNurseScript` (lobby heal) | `src/script/gen2/Vm.lua` `jumpstd` + std-script table | implemented |
-| `TeleportGuyScript` warp to New Bark Town, `AbraScript` `cry ABRA` | generic `warp`/`yesorno`/`cry` opcodes | implemented (data-driven) |

-| Hall of Fame roster screen + credits, first-time-champion skip lockout | `src/ui/gen2/HallOfFame.lua`, `src/ui/gen2/Credits.lua`; eyeball driver `tests/drivers/gold_halloffame_shots.lua` | implemented |
-| `wSpawnAfterChampion` -> post-credits respawn at `SPAWN_NEW_BARK` | `src/core/gen2/HallOfFame.lua:51` (`POST_CREDITS_SPAWN`) and `:254` (`consumePostGameSpawn`) | **partial** - the logic exists and is unit-tested (`tests/gen2_halloffame_test.lua:164`), but grepping `src/` finds **no caller**: nothing on the CONTINUE path consumes it, so a port save resumes where it stood rather than at New Bark Town |
-| `specialphonecall SPECIALCALL_SSTICKET` from the induction | `src/script/gen2/Vm.lua` (`specialphonecall`), `src/core/gen2/Phone.lua:394` (`SPECIALCALL_SSTICKET`, id 5) | implemented |
-| `ENGINE_FLYPOINT_INDIGO_PLATEAU` -> Fly menu + Kanto map unlock | `src/world/gen2/FieldMoves.lua:368` (`SPAWN_INDIGO`, flag 63), `:414` (Kanto half gate) | implemented |
-| `ENGINE_INDIGO_PLATEAU_RIVAL_FIGHT` daily reset | `src/core/gen2/Apricorns.lua:88` (`DAILY_ENGINE_FLAGS`, id 92) | implemented |
-| A Gold-side driver that actually walks Route 23 -> Hall of Fame | none found (`tests/drivers/gold_*.lua` has boot/walk/battle/HOF-screen drivers but no League run; `tests/drivers/bot_route.lua` and `tests/parity_lance.lua` are the **Gen 1** Kanto Elite Four) | missing |

-
-## 6. Unresolved / verify by hand
-
-1. **"Route 32 is very short, and you'll immediately be at the Pokémon League
-   building."** The map between Victory Road and the Plateau is `MAP_ROUTE_23`
-   (`constants/map_constants.asm:322`), not Route 32 (which is south of Violet
-   City). Walkthrough typo.
-2. **The walkthrough is describing HeartGold/SoulSilver parties, not Gold.** Four
-   concrete divergences, all verified against `data/trainers/parties.asm`:
-   - Will's send-out order is Xatu, Jynx, **Exeggutor, Slowbro**, Xatu; the FAQ
-     lists Slowbro third and Exeggutor fifth.
-   - Koga's order is Ariados, **Venomoth, Forretress**, Muk, Crobat; the FAQ
-     swaps 2 and 3.
-   - Bruno's order is Hitmontop, **Hitmonlee, Hitmonchan**, Onix, Machamp; the
-     FAQ swaps 2 and 3.
-   - Karen and Lance match in order and level.
-3. **Prize money.** The FAQ's 4200 / 4400 / 4600 / 4700 / 5000 G are 100 x the
-   last mon's level (HGSS). GS pays `base reward x level`
-   (`ComputeTrainerReward`, `engine/battle/read_trainer_party.asm:300`) with a
-   base reward of 25 for every one of these classes
-   (`data/trainers/attributes.asm`), i.e. **1050 / 1100 / 1150 / 1175 / 1250 G**.
-   The EXP figures quoted per Pokémon were not checked against
-   `data/pokemon/base_stats/` and should be treated as HGSS numbers too.
-4. **Held items and AI items.** "Koga has three Full Restores", "Karen has one
-   Full Restore", "Lance has three Full Restores", "Houndoom holding a Sitrus
-   Berry", "One of the Dragonites may be holding a Sitrus Berry". In GS these
-   parties are `TRAINERTYPE_MOVES`, which carries **no held item field at all**,
-   and the AI's item pool is the two-byte class row: Will `MAX_POTION, NO_ITEM`;
-   Bruno `MAX_POTION, NO_ITEM`; Karen `FULL_HEAL, MAX_POTION` (no Full Restore);
-   Koga `FULL_HEAL, FULL_RESTORE`; Champion `FULL_HEAL, FULL_RESTORE`. Sitrus
-   Berry does not exist in Gen 2.
-5. **Move names.** "Dragon Rush" (Lance's Dragonites) is a Gen 4 move; the GS
-   Dragonites run Thunder Wave / Twister / Thunder or Blizzard / Hyper Beam, and
-   the level-50 one runs Fire Blast / Safeguard / Outrage / Hyper Beam. Lugia's
-   "Aero Blast" and Donphan/Sudowoodo suggestions in the sample lineup are fine
-   as species, but none of that is asm-checkable.
-6. **"Routes 46 and 47 aren't bad, either."** `ROUTE_47` does not exist in
-   pokegold (`constants/map_constants.asm` has `ROUTE_45` and `ROUTE_46` and then
-   moves on). Route 47/48 are HGSS additions.
-7. **"You can go back to the Move Deleter in Blackthorn City."** There is a
-   `maps/MoveDeletersHouse.asm` reached from `maps/BlackthornCity.asm`; I did not
-   read its script, so the claim is plausible but unverified here.
-8. **"If you trade a Red Scale to Mr. Pokémon, he will give you EXP Share."**
-   `maps/MrPokemonsHouse.asm` does `checkitem RED_SCALE` (line 53),
-   `verbosegiveitem EXP_SHARE` (line 72), `takeitem RED_SCALE` (line 74), so the
-   claim holds; the surrounding flag guards were not read (out of scope).
-9. **The "Abra" sprite.** `maps/IndigoPlateauPokecenter1F.asm:324` declares
-   `SPRITE_JYNX` for the object whose script is `AbraScript` and whose cry is
-   `cry ABRA`. There is no `SPRITE_ABRA` in `constants/sprite_constants.asm`.
-   Whether this renders as a Jynx on hardware, or whether some `variablesprite`
-   elsewhere rewrites it, was not chased down - no `variablesprite` targeting
-   `SPRITE_JYNX` appears in `engine/events/std_scripts.asm`'s init block.
-10. **`EVENT_LANCES_ROOM_EXIT_OPEN` is never set.** `LancesRoomDoorsCallback`
-    reads it, the lobby callback clears it, but no script in the tree sets it
-    (grepped `maps/`). The champion's north door is opened by a bare
-    `changeblock 4, 0, $0b`, which does not survive a map reload. Harmless in
-    practice because the script warps you out immediately, but a bot that
-    somehow re-enters Lance's room post-battle will find the door shut again.
-11. **`setevent EVENT_LANCES_ROOM_ENTRANCE_CLOSED` appears twice**: once in
-    `LancesRoomDoorLocksBehindYouScript` (correct) and again immediately after
-    the champion's after-battle text in `LancesRoomLanceScript`. The second one
-    looks like it was meant to be the `EXIT_OPEN` set in item 10; recorded as
-    observed, not corrected.
-12. **The lobby's redundant `setscene`.** `PlateauRivalPostBattle` sets the scene
-    to `SCENE_INDIGOPLATEAUPOKECENTER1F_RIVAL_BATTLE`, which is 0, which is the
-    map's only scene and its default. Whether this was intended to disarm the
-    coord events (it does not) is a judgement call; the effective guards are the
-    engine flag and the weekday check.
-13. **"Fully heal your Pokémon and save after every trainer battle."** There is
-    no heal source inside the sealed rooms - no nurse object, no
-    `special HealParty` until `HallOfFameEnterScript`. The advice is about bag
-    items, and the asm agrees that nothing else is available.

-
- `Route6PokefanMScript` (`maps/Route6.asm:9`, sym `4f:581a`): a bare `jumptextfaceplayer Route6PokefanMText` - "The road is closed until the problem at the POWER PLANT is solved." No flag reads. He stands at `(17, 4)`, directly south of the Underground Path door at `(17, 3)`, so his body is the block, not a script check.

-
-`(1,5)` in the top-left room is the only pad that reaches Sabrina, and `(11,9)` is the only way out of her chamber. This matches the walkthrough's "go to the bottom left teleporter and you'll go straight to the gym leader".
-
-**Coord events** - none. The gym has no trip-wires; every transition is a warp tile.

-
-All four trainers spin (`SPINRANDOM_FAST`), so their line of sight rotates - a bot cannot assume a fixed approach lane; walking into the room will trigger them.
-
-**Scripts of interest**
-
- `SaffronGymSabrinaScript` (`maps/SaffronGym.asm:14`, sym `61:40cf`):
-  `faceplayer` / `opentext` / `checkflag ENGINE_MARSHBADGE` / `iftrue .FightDone` / `writetext SabrinaIntroText` / `waitbutton` / `closetext` / `winlosstext SabrinaWinLossText, 0` / `loadtrainer SABRINA, SABRINA1` / `startbattle` / `reloadmapafterbattle` / then a burst of five `setevent`s: `EVENT_BEAT_SABRINA`, `EVENT_BEAT_MEDIUM_REBECCA`, `EVENT_BEAT_MEDIUM_DORIS`, `EVENT_BEAT_PSYCHIC_FRANKLIN`, `EVENT_BEAT_PSYCHIC_JARED` / `opentext` / `writetext ReceivedMarshBadgeText` / `playsound SFX_GET_BADGE` / `waitsfx` / `setflag ENGINE_MARSHBADGE` / `writetext SabrinaMarshBadgeText` / `waitbutton` / `closetext` / `end`.
-  Two consequences a bot should exploit: **the four gym trainers are auto-cleared when Sabrina falls**, so they are entirely skippable; and the badge is a `setflag` on `ENGINE_MARSHBADGE`, which is also the re-entry guard (`.FightDone`).
- `TrainerMediumRebecca` / `TrainerPsychicFranklin` / `TrainerMediumDoris` / `TrainerPsychicJared` (`maps/SaffronGym.asm:47,58,69,80`): each is a `trainer CLASS, ID, EVENT_BEAT_*, SeenText, BeatenText, 0, .Script` struct (`macros/scripts/maps.asm:142`; field order is group, id, flag, seen, win, loss, after) followed by an `endifjustbattled` / `opentext` / `writetext ...AfterBattleText` / `waitbutton` / `closetext` / `end` after-battle script.
- `SaffronGymStatue` (`maps/SaffronGym.asm:107`, sym `61:4170`): `checkflag ENGINE_MARSHBADGE` / `iftrue .Beaten` / `jumpstd GymStatue1Script`; the beaten arm does `gettrainername STRING_BUFFER_4, SABRINA, SABRINA1` then `jumpstd GymStatue2Script`. Handy as a cheap post-badge assertion.
- `SaffronGymGuideScript` (`maps/SaffronGym.asm:91`): branches on `checkevent EVENT_BEAT_SABRINA`; no items, no flags written.
-
-**Flags and events**
-
-| constant | defined in | read/written by | meaning for a bot |
-|---|---|---|---|
-| `ENGINE_MARSHBADGE` | `constants/engine_flags.asm:52` (bit 5 of `wKantoBadges`; Kanto order is Boulder, Cascade, Thunder, Rainbow, Soul, **Marsh**, Volcano, Earth) | `checkflag` in `SaffronGymSabrinaScript` and `SaffronGymStatue`; `setflag` after the win | The section's terminal postcondition |
-| `EVENT_BEAT_SABRINA` | `constants/event_flags.asm:720` | set by `SaffronGymSabrinaScript`; read by `SaffronGymGuideScript` | Leader defeated |
-| `EVENT_BEAT_MEDIUM_REBECCA` | `constants/event_flags.asm:935` | trainer struct flag; also force-set by the Sabrina script | Rebecca cleared |
-| `EVENT_BEAT_MEDIUM_DORIS` | `constants/event_flags.asm:936` | as above | Doris cleared |
-| `EVENT_BEAT_PSYCHIC_FRANKLIN` | `constants/event_flags.asm:564` | as above | Franklin cleared |
-| `EVENT_BEAT_PSYCHIC_JARED` | `constants/event_flags.asm:573` | as above | Jared cleared |

-| `MEDIUM` / `REBECCA` | `MEDIUM` | 6 (`constants/trainer_constants.asm:590`) | `MediumGroup` `; MEDIUM (6)`: L35 `DROWZEE`, L35 `HYPNO` | `TrainerMediumRebecca` | none |
-| `PSYCHIC_T` / `FRANKLIN` | `PSYCHIC_T` (class 34) | 2 (`constants/trainer_constants.asm:513`) | `PsychicGroup` `; PSYCHIC_T (2)` (`data/trainers/parties.asm:2516`): L37 `KADABRA` | `TrainerPsychicFranklin` | none |

-
-Prize money: `ComputeTrainerReward` (`engine/battle/read_trainer_party.asm:300`) is `base reward x last mon's level`, and `engine/battle/core.asm:2344-2358` pays that quarter out **four times**, so the visible payout is `4 x base x level`. Base rewards: Sabrina 25 (`data/trainers/attributes.asm:211`), Medium 10 (`:343`), Psychic T 8 (`:313`). That reproduces the walkthrough's 4800G / 1400G / 1440G / 1184G / 1120G exactly. Sabrina also carries a `HYPER_POTION` as an AI item (`data/trainers/attributes.asm:210`).

-**Wild encounters** - none (indoor gym).

-## 3. Blockers and gates
-
-| Gate | Enforced by (file:label) | Requirement | Unlock condition |
-|---|---|---|---|
-| Underground Path (Route 6 warp 1 at `(17, 3)`) | `maps/Route6.asm:43` - `ROUTE6_POKEFAN_M` object standing at `(17, 4)` with event flag `EVENT_ROUTE_5_6_POKEFAN_M_BLOCKS_UNDERGROUND_PATH`; visibility decided by `CheckObjectFlag`, `engine/overworld/map_objects_2.asm:32` | Nothing the player can do in this section | `maps/PowerPlant.asm:164` `setevent EVENT_ROUTE_5_6_POKEFAN_M_BLOCKS_UNDERGROUND_PATH` (flag set = object masked), which is part of returning the `MACHINE_PART` |
-| Magnet Train Saffron -> Goldenrod | `maps/SaffronMagnetTrainStation.asm:19` `checkevent EVENT_RESTORED_POWER_TO_KANTO`, then `checkitem PASS` at `:30` | `EVENT_RESTORED_POWER_TO_KANTO` **and** `PASS` in bag | `maps/PowerPlant.asm:165` sets the event; the `PASS` comes from elsewhere. Both false here, so the officer only prints "isn't operating now" |
-| Silph Co. upper floors | `maps/SilphCo1F.asm:69` - `SILPHCO1F_OFFICER` object at `(13, 1)` with event flag `-1` (never hides). No stairs warp exists on `SilphCo1F` at all | Permanently blocked in Gen 2 | Never; this is not a gate that opens |
-| Saffron Gym maze | The 30 pad warps at `maps/SaffronGym.asm:296-326`. Pads are teleport panels (`COLL_WARP_PANEL`-class tiles), so they fire on landing, not on a directional press | Navigation only - no badge, item or flag check anywhere in `SaffronGym.asm` | n/a. The single route to Sabrina is `(11,15) -> (19,17) -> ... -> (1,5) -> (11,9)`; see the pad table |
-| MARSHBADGE re-fight guard | `maps/SaffronGym.asm:17` `checkflag ENGINE_MARSHBADGE` / `iftrue .FightDone` | Badge not yet held | Beating Sabrina once; afterwards she only talks |
-| Gym trainers | Each `trainer` struct's `EVENT_BEAT_*` flag; the trainer only challenges while its flag is clear | Walking into their sight cone (sight 3 for Rebecca/Franklin, 2 for Doris/Jared) | Beating them, **or** beating Sabrina, which sets all four flags at `maps/SaffronGym.asm:27-30` |
-
-No HM field move is required anywhere in this section - no `engine/overworld/cut.asm`, `surf.asm`, `strength.asm` or `whirlpool.asm` check is reachable from these maps. The Bicycle the walkthrough recommends is convenience only.
-
-## 4. Bot checklist
-
-Coordinates are asm cell coordinates on the named map. "Warp N" means the `def_warp_events` index in that map's table.
-
-1. `MAP_ROUTE_6` - walk north along the route to warp 2 at `(6, 1)`. Precondition: none. Postcondition: on `MAP_ROUTE_6_SAFFRON_GATE` warp 3 `(4, 7)`.
-   - Optional: read the sign at `(19, 5)`. Do **not** try warp 1 at `(17, 3)`; `ROUTE6_POKEFAN_M` occupies `(17, 4)` while `EVENT_ROUTE_5_6_POKEFAN_M_BLOCKS_UNDERGROUND_PATH` is clear.
-2. `MAP_ROUTE_6_SAFFRON_GATE` - walk from `(4, 7)` to warp 1 at `(4, 0)`. Postcondition: on `MAP_SAFFRON_CITY` warp 12 `(16, 33)`; `MAPCALLBACK_NEWMAP` fires and `ENGINE_FLYPOINT_SAFFRON` becomes set.
-3. `MAP_SAFFRON_CITY` - walk to warp 5 at `(27, 29)`. Enter `MAP_MR_PSYCHICS_HOUSE`.
-4. `MAP_MR_PSYCHICS_HOUSE` - talk to `MRPSYCHICSHOUSE_FISHING_GURU` at `(5, 3)` (approach from `(4, 3)` facing right, he faces left). Precondition: `EVENT_GOT_TM29_PSYCHIC` clear and TM pocket has room. Postcondition: `TM_PSYCHIC_M` in bag, `EVENT_GOT_TM29_PSYCHIC` set. Exit warp 1 `(2, 7)`.
-5. `MAP_SAFFRON_CITY` - walk to warp 7 at `(18, 21)`. Enter `MAP_SILPH_CO_1F`.
-6. `MAP_SILPH_CO_1F` - talk to `SILPHCO1F_OFFICER` at `(13, 1)`. Precondition: `EVENT_GOT_UP_GRADE` clear, item pocket has room. Postcondition: `UP_GRADE` in bag, `EVENT_GOT_UP_GRADE` set. Exit warp 1 `(2, 7)`.
-7. (Optional, dialogue only) `MAP_SAFFRON_CITY` warp 6 at `(8, 3)` -> `MAP_SAFFRON_MAGNET_TRAIN_STATION`; talk to `SAFFRONMAGNETTRAINSTATION_OFFICER` at `(9, 9)`. Expect the "isn't operating now" arm because `EVENT_RESTORED_POWER_TO_KANTO` is clear. Exit warp 1 `(8, 17)`.
-8. (Optional) `MAP_SAFFRON_CITY` warp 3 at `(25, 11)` -> `MAP_SAFFRON_MART`; talk to `SAFFRONMART_CLERK` at `(1, 3)` for `MART_SAFFRON`. Exit warp 1 `(2, 7)`.
-9. `MAP_SAFFRON_CITY` - warp 1 at `(26, 3)` -> `MAP_FIGHTING_DOJO`. Walk onto / face `FIGHTINGDOJO_POKE_BALL` at `(3, 1)`. Precondition: `EVENT_PICKED_UP_FOCUS_BAND` clear. Postcondition: `FOCUS_BAND` in bag, `EVENT_PICKED_UP_FOCUS_BAND` set (ball object masked from then on). Exit warp 1 `(4, 11)`.
-10. (Optional heal) `MAP_SAFFRON_CITY` warp 4 at `(9, 29)` -> `MAP_SAFFRON_POKECENTER_1F`; talk to nurse at `(3, 1)`. Exit warp 1 `(3, 7)`.
-11. `MAP_SAFFRON_CITY` - warp 2 at `(34, 3)` -> `MAP_SAFFRON_GYM`, landing on warp 1 `(8, 17)`.
-12. `MAP_SAFFRON_GYM` - walk to the pad at `(11, 15)`. Warps to `(19, 17)`.
-13. `MAP_SAFFRON_GYM` BR room - battle `SAFFRONGYM_GRANNY1` (Medium Rebecca) at `(17, 16)`, sight 3. Precondition: `EVENT_BEAT_MEDIUM_REBECCA` clear. Postcondition: that flag set. (Skippable: her flag is force-set by the Sabrina script.)
-14. `MAP_SAFFRON_GYM` - step on pad `(15, 17)`. Warps to `(5, 15)`.
-15. `MAP_SAFFRON_GYM` BL room - battle `SAFFRONGYM_YOUNGSTER1` (Psychic Franklin) at `(3, 16)`, sight 3. Postcondition: `EVENT_BEAT_PSYCHIC_FRANKLIN` set.
-16. `MAP_SAFFRON_GYM` - step on pad `(1, 15)`. Warps to `(19, 5)`.
-17. `MAP_SAFFRON_GYM` TR room - battle `SAFFRONGYM_YOUNGSTER2` (Psychic Jared) at `(17, 4)`, sight 2. Postcondition: `EVENT_BEAT_PSYCHIC_JARED` set.
-18. `MAP_SAFFRON_GYM` - step on pad `(15, 5)`. Warps to `(1, 3)`.
-19. `MAP_SAFFRON_GYM` TL room - battle `SAFFRONGYM_GRANNY2` (Medium Doris) at `(3, 4)`, sight 2. Postcondition: `EVENT_BEAT_MEDIUM_DORIS` set.
-20. `MAP_SAFFRON_GYM` - step on pad `(1, 5)`. Warps to `(11, 9)`, Sabrina's chamber.
-21. `MAP_SAFFRON_GYM` - talk to `SAFFRONGYM_SABRINA` at `(9, 8)` (stand at `(9, 9)` facing up, or `(10, 8)` facing left). Precondition: `ENGINE_MARSHBADGE` clear. Battle `SABRINA`/`SABRINA1`. Postcondition: `EVENT_BEAT_SABRINA`, the four trainer flags, and `ENGINE_MARSHBADGE` all set; +4800G.
-22. `MAP_SAFFRON_GYM` exit - `(11, 9)` -> `(1, 5)`; walk right to `(5, 5)` -> `(1, 11)`; walk right to `(5, 11)` -> `(5, 17)`; walk up to `(5, 15)` -> `(15, 17)`; walk right to `(19, 17)` -> `(11, 15)`; walk down to warp 1/2 at `(8, 17)`/`(9, 17)` -> `MAP_SAFFRON_CITY` warp 2 `(34, 3)`.
-23. Mid-gym heal-and-return (if step 21 needs a fresh party): exit via step 22, heal at `MAP_SAFFRON_POKECENTER_1F`, re-enter, then `(11,15) -> (19,17)`, up to `(19,15) -> (19,9)`, left to `(15,9) -> (15,3)`, down to `(15,5) -> (1,3)`, down to `(1,5) -> (11,9)`. This is the walkthrough's "1st teleporter, then up, left, down, down" and it checks out against the pad table.

-## 5. Port coverage
-
-| Beat | Port file | Status |
-|---|---|---|
-| Map load, block grid, `COLL_*` collision, connections | `src/world/gen2/Map.lua`, `src/world/gen2/Permissions.lua`, `src/world/gen2/World.lua` | Implemented (generic; Gold maps come from `src/import/RomExtractorGen2.lua`, not hand-ported) |
-| Warp panels / teleport pads (the whole gym maze) | `src/world/gen2/Permissions.lua:195` `COLL_WARP_PANEL = 0x7c` in `WARP_FACING_DOWN`, `Permissions.warpFacesDown`; warp taking in `src/world/gen2/World.lua:1566` `World:warpTo` | Implemented (panels warp on landing, which is what all 30 gym pads are) |
-| Map-to-self warps (every gym pad targets `SAFFRON_GYM`) | `src/world/gen2/World.lua` warp handling | Implemented, but untested for this map - no driver exercises a same-map warp chain |
-| `MAPCALLBACK_NEWMAP` -> `setflag ENGINE_FLYPOINT_SAFFRON` | `src/world/gen2/World.lua:5659` `self:runMapCallback("MAPCALLBACK_NEWMAP")`; fly-point row at `src/world/gen2/FieldMoves.lua:365` (`LANDMARK_SAFFRON_CITY` / `SPAWN_SAFFRON` / flag 59) | Implemented |
-| Script opcodes used by every script in this section (`checkevent`, `iftrue`, `iffalse`, `setevent`, `checkflag`, `setflag`, `verbosegiveitem`, `promptbutton`, `writetext`, `waitbutton`, `jumptext`, `jumptextfaceplayer`, `jumpstd`, `gettrainername`, `pokemart`, `yesorno`, `checkitem`, `applymovement`, `special`, `warpcheck`, `newloadmap`, `loadtrainer`, `startbattle`, `reloadmapafterbattle`, `winlosstext`, `endifjustbattled`, `playsound`, `waitsfx`) | `src/script/gen2/Opcodes.lua`, `src/script/gen2/Vm.lua` (`checkflag` :195, `verbosegiveitem` :490, `pokemart` :597, `jumpstd` :742, `loadtrainer` :806, `startbattle` :817, `winlosstext` :918) | Implemented |
-| Object visibility from event flags (the Route 6 blocker, the station's hidden Teacher/Lass, the picked-up Focus Band ball) | `src/world/gen2/Events.lua:1-2` documents and implements "flag SET -> object hidden", matching `CheckObjectFlag` | Implemented |
-| Overworld trainer sight + battle handoff (Rebecca, Franklin, Doris, Jared) | `src/world/gen2/Trainers.lua` (eyesight from `home/trainers.asm`, party build) | Implemented |
-| Gym leader battle, badge grant, prize money x4 | `src/battle/gen2/Battle.lua`; `src/battle/gen2/Prize.lua:82` `Prize.reward(baseMoney, level)` and `:181` `local quarter = ...` (the four-way payout) | Implemented |
-| Item ball pickup (`FOCUS_BAND` in the Fighting Dojo) | Extracted at `src/import/RomExtractorGen2.lua:2968-2969` into `obj.itemball`, but **nothing reads `obj.itemball` at runtime** (grep for `.itemball` in `src/` hits only the extractor). `src/script/gen2/CallAsm.lua:551` explicitly stubs `TryReceiveItem` | **Missing** - the ball object will exist and be masked correctly by its flag, but stepping on it grants nothing |
-| Magnet Train ride (`special MagnetTrain`) | `src/core/gen2/MagnetTrain.lua`, `src/ui/gen2/MagnetTrainRide.lua` | Implemented (not exercised in this section - the officer's gate is false here) |
-| Mart (`pokemart MARTTYPE_STANDARD, MART_SAFFRON`) | `src/ui/gen2/MartMenu.lua`, `Vm.lua:597` | Implemented |
-| Pokecenter heal (`jumpstd PokecenterNurseScript`) | std scripts extracted (`src/import/RomExtractorGen2.lua:2901`), heal hook `src/script/gen2/Specials.lua:451` | Implemented |
-| Bicycle | `src/world/gen2/Bike.lua` | Implemented |
-| Any Saffron-specific hand-ported content | none | **Missing by design** - the Gen 2 port is data-driven off the ROM; there are no `SAFFRON` symbols anywhere under `src/` except Gen 1 save-conversion tables (`src/save_convert/`), which are unrelated |
-| Driver coverage for this section | `tests/drivers/gold_*.lua` (25 drivers: boot, walk, warp, trainer, battle, map callbacks, ...) | **Missing** - no driver reaches Kanto or Saffron; `gold_warp_scene.lua` / `gold_walk_smoke.lua` are Johto-early smoke tests |
-
-## 6. Unresolved / verify by hand
-
- **Psychic Jared's third Pokemon.** The walkthrough lists "Level 32 Exeggcute (672 EXP)" twice. `data/trainers/parties.asm:2569-2574` gives `PSYCHIC_T (11) JARED` as L32 `MR__MIME`, L32 `EXEGGCUTE`, **L35** `EXEGGCUTE`. The asm wins; the walkthrough's second Exeggcute level and its EXP figure are both wrong.
- **EXP values.** None of the per-Pokemon EXP numbers in the walkthrough (765, 1237, 1149, 735, 672, 720, 1264, 1941, 1339, 1912) were checked against `data/pokemon/base_stats/` - they are outside what a bot needs and were not verified.
- **"PokeMart ... upper-right corner of Saffron City".** The mart door is warp 3 at `(25, 11)` on a 40x36-cell map, i.e. north-of-centre and east of the middle, not the corner. The two gyms it says are "further north" are at `(26, 3)` and `(34, 3)`, which is correct.
- **"Silph Co ... the multi-story building above the Pokémon Center".** Silph is warp 7 at `(18, 21)`; the Pokecenter is warp 4 at `(9, 29)`. Silph is north-**east** of it, and `SilphCo1F` has no stairs warp - only the two street doors. There is no upper floor in Gen 2.
- **"You now have 10 badges!"** `ENGINE_MARSHBADGE` is bit 5 of `wKantoBadges` (`constants/engine_flags.asm:52`), so it is the 6th Kanto badge in flag order, not the 10th badge overall. The count of 10 only holds for a player who took Vermilion before Saffron, as this FAQ's chapter order does. Nothing in the asm enforces that order.
- **The walkthrough's mid-maze "left/right (whichever way works) till you find that one trainer again (Franklin)" heal route** is deliberately vague in the source text and was not reduced to a single pad sequence. The precise post-heal route it gives afterwards ("1st teleporter, then up, left, down, down") *does* resolve cleanly and is recorded in bot checklist step 23.
- **The "large man who blocks the entire entrance to the Underground Path"** is described as taunting the player about moving boulders. `Route6PokefanMText` (`maps/Route6.asm:15`) contains only the Power Plant line; no boulder or strength text exists on this map. Treat the boulder remark as FAQ colour.

-# Section 21 - Power Plant and Cerulean City Gym
-
-Source: `../section-21-power-plant-and-cerulean-city-gym.txt`
-Maps covered: `MAP_ROUTE_5`, `MAP_ROUTE_5_SAFFRON_GATE`, `MAP_ROUTE_5_CLEANSE_TAG_HOUSE`,
-`MAP_ROUTE_5_UNDERGROUND_PATH_ENTRANCE`, `MAP_CERULEAN_CITY`, `MAP_CERULEAN_GYM`,
-`MAP_ROUTE_9`, `MAP_ROUTE_10_NORTH`, `MAP_POWER_PLANT`, `MAP_ROUTE_24`,
-`MAP_ROUTE_25`, `MAP_BILLS_HOUSE`
-Badges / key milestones in this section: CASCADEBADGE (`ENGINE_CASCADEBADGE`) from Misty;
-the whole Machine Part chain (`EVENT_MET_MANAGER_AT_POWER_PLANT` ->
-`EVENT_MET_ROCKET_GRUNT_AT_CERULEAN_GYM` -> Route 24 grunt battle ->
-`EVENT_FOUND_MACHINE_PART_IN_CERULEAN_GYM`); Misty's date on Route 25 clears
-`EVENT_TRAINERS_IN_CERULEAN_GYM` and is what actually populates the gym.
-
-Coordinate note: `warp_event` / `bg_event` / `object_event` / `coord_event` x,y are in
-*map cells* (walk tiles), while `map_const NAME, W, H` in `constants/map_constants.asm`
-is in *blocks*. Cells = 2x blocks, so `map_const ROUTE_9, 30, 9` is a 60x18 cell map and
-`warp_event 48, 15` is inside it.

-Spills into the next section: `maps/Route9.asm` warp 1 at `48,15` leads to `ROCK_TUNNEL_1F`,
-and the Machine Part is *returned* to `PowerPlantManager` (which is what unlocks the Magnet
-Train and the Underground Path). The walkthrough text stops at Misty; Rock Tunnel / Lavender

-
-**Scripts of interest**
-
- `Route5PokefanMScript` - one `jumptextfaceplayer Route5PokefanMText`: "The road is closed
-  until the problem at the POWER PLANT is solved." He stands at `17,16`, directly below the
-  Underground Path door at `17,15`, so the tile is physically blocked. His object row carries
-  `EVENT_ROUTE_5_6_POKEFAN_M_BLOCKS_UNDERGROUND_PATH`; object events are hidden when their
-  flag is *set*, and that flag is not in `InitializeEventsScript`, so at this point in the
-  game it is clear and he is present. `PowerPlantManager` `setevent`s it after the part is
-  returned (`maps/PowerPlant.asm:164`), removing him.
- `Route5UndergroundPathSign` / `HouseForSaleSign` - plain `jumptext`. Note the "House for
-  Sale" sign shares the exact tile `10,11` with warp 4 into the Cleanse Tag house.

-| Hidden items (`BGEVENT_ITEM`): MACHINE_PART, ETHER, POTION, BERSERK_GENE | `src/world/gen2/HiddenItems.lua` | implemented (the header notes this was previously unreachable because `World:bgEventAt` only answered `BGEVENT_READ`) |

-| Prize money = base x level x 4 (Misty 4700G etc.) | `src/battle/gen2/Prize.lua:12` (documents the `ld c, 4` loop), `Prize.reward` at `:82` | implemented, incl. Amulet Coin and Mom's savings split |
-| CUT gate on HIVEBADGE + cut-tree collision | `src/world/gen2/FieldMoves.lua:440` `badgeGate` / `:452`; `src/world/gen2/Permissions.lua:130` `CUT_TREE`, `:152` `CheckCutCollision` set | implemented |

-## 6. Unresolved / verify by hand
-
- **Cut tree positions.** The walkthrough says "Cut the tree at the entrance" (Route 9) and
-  "Cut the tree above Pat" (Route 25). Cut trees are block data in `maps/Route9.blk` /
-  `maps/Route25.blk`, not events, so no coordinate for them appears anywhere in the asm text.
-  A bot needs the decoded block map (or the port's `Permissions.isCutTree` over the loaded
-  collision) to find them. The Protein ball at `32,4` sitting two cells above Pat at `31,7`
-  is consistent with the walkthrough's claim, but the tree cell itself is unverified here.
- **Kevin's battle is omitted from the walkthrough.** The text says only "that guy will give
-  you a Nugget". `TrainerCooltrainermKevin` gives the NUGGET and then immediately battles you
-  with L38 RHYHORN / L35 CHARMELEON / L35 WARTORTLE. Treat the walkthrough as incomplete here,
-  not the asm.
- **Wild lists are abridged in the walkthrough.** Route 24 also has VENONAT / SUNKERN /
-  ODDISH / VENOMOTH, and Route 25 also has PIDGEY / PIDGEOTTO / VENONAT / WEEPINBELL /
-  ODDISH / VENOMOTH, none of which the FAQ lists. Route 5's own table (PIDGEY / BELLSPROUT /
-  ABRA / ODDISH / GLOOM) is not listed at all.
- **"Surf down the river ... and you'll be at the Power Plant."** The Power Plant door is
-  `warp_event 3, 9` on `ROUTE_10_NORTH`, and the water table for both `ROUTE_9` and
-  `ROUTE_10_NORTH` exists, so surfing is clearly the route - but the exact water path across
-  the Route 9 / Route 10 North connection boundary is block data and was not traced.
- **EXP values.** Every per-mon EXP number in the walkthrough (e.g. "Level 42 Golduck
-  (1566 EXP)") depends on the player's own level and participation; nothing in
-  `data/trainers/parties.asm` carries them. Money values were all reproduced from
-  `data/trainers/attributes.asm` base reward x last-mon level x 4 and check out.
- **"the 11th gym badge".** The asm has no badge counter tied to this; `ENGINE_CASCADEBADGE`
-  is just one bit in `constants/engine_flags.asm:48`. The ordinal is walkthrough prose.
- **Route 5 "Day Care Center from Red, Blue and Yellow".** The building is
-  `ROUTE_5_CLEANSE_TAG_HOUSE` and its sign at `10,11` reads "House for Sale... Nobody lives
-  here." Nothing in Gen 2 calls it a Day Care; that identification is the FAQ's own history
-  note. Also note the sign and the door share the tile `10,11`, so an A-press there may hit
-  either depending on facing - worth verifying against the port's bg-event-vs-warp priority.
- **`POWERPLANT_GYM_GUIDE3` / `PowerPlantGymGuide4Script` naming mismatch** in
-  `maps/PowerPlant.asm` (there is no `PowerPlantGymGuide3Script`). Harmless, but a
-  label-driven bot should not assume the const and script numbers line up.

-  `(6,6) (8,6) (10,6) (12,8) (4,8) (10,10)`. This is the wall the FAQ hits.
-  Block coordinates, so the blocked cells are `x = 2*bx .. 2*bx+1`,
-  `y = 2*by .. 2*by+1`.
- `Route19Fisher1Script` / `Route19Fisher2Script` both branch on

-Note the object-flag polarity (`CheckObjectFlag`,

-`EVENT_VERMILION_CITY_SNORLAX` is clear, and `disappear` is what sets it.
-
-**Scripts of interest**
-
- `VermilionSnorlax` (`4f:5291`). `opentext` -> `special SnorlaxAwake` ->
-  `iftrue .Awake`. Asleep branch writes `VermilionCitySnorlaxSleepingText` and
-  ends. `.Awake` writes `VermilionCityRadioNearSnorlaxText`, `pause 15`,
-  `cry SNORLAX`, then
-  `loadvar VAR_BATTLETYPE, BATTLETYPE_FORCEITEM` /
-  `loadwildmon SNORLAX, 50` / `startbattle` /
-  `disappear VERMILIONCITY_BIG_SNORLAX` / `setevent EVENT_FOUGHT_SNORLAX` /
-  `reloadmapafterbattle`.
-  The `disappear` and `setevent` run **unconditionally after the battle**, so a
-  fled-from or fainted Snorlax is still gone: catching it is a one-shot.
- `SnorlaxAwake` (`engine/events/specials.asm:358`, symbol `03:45d6`). Returns
-  `TRUE` only when *both* hold:
-  1. `[wMapMusic] == MUSIC_POKE_FLUTE_CHANNEL`;
-  2. the player stands on one of `.ProximityCoords`
-     (`engine/events/specials.asm:399`): `(33,8) (34,10) (35,10) (36,8) (36,9)`.
-  The POKe FLUTE channel is the Pokegear radio at knob 78 / "20.0"
-  (`engine/pokegear/pokegear.asm:1447`, `.PokeFluteRadio` at 1487): it needs
-  **not-Johto** and `POKEGEAR_EXPN_CARD_F` in `wPokegearFlags`. Tuning the radio
-  and closing the Pokegear leaves that song as `wMapMusic`.
- `VermilionGymBadgeGuy`: `checkevent EVENT_GOT_HP_UP_FROM_VERMILION_GUY`, then
-  `readvar VAR_BADGES` with `ifequal NUM_BADGES` / `ifgreater 13` /
-  `ifgreater 9`. `verbosegiveitem HP_UP` only at all 16 badges. Not this
-  section's business, but a bot walking Vermilion will trip the text.
- `VermilionCityFlypointCallback` (`MAPCALLBACK_NEWMAP`):
-  `setflag ENGINE_FLYPOINT_VERMILION`. This is what makes the FAQ's "fly back to
-  Vermilion City" legal - it must already have been visited on foot.

-`loadwildmon SNORLAX, 50`. Level 50 learnset from
-`data/pokemon/evos_attacks.asm:1932`: the four most recent are SNORE (36),
-REST (36), BODY_SLAM (43), ROLLOUT (50) - which is exactly the FAQ's "Rest" and

-  two text branches ("A sleeping #MON is lying in front of DIGLETT'S CAVE" ->

-Warps 2<->5 and 4<->6 are the two internal ladders. Reading `DiglettsCave.blk`
-against `data/tilesets/kanto_collision.asm` (block `$1f`/`$1b` = ladder, `$24` =
-door) the map is three disconnected pockets:
-
- pocket A (bottom-left, blocks (1,15)-(2,17)): warp 1 (VERMILION door) + warp 2
-  (ladder);
- pocket B (the long cave): warp 5 at (17,33) up to warp 6 at (3,3);
- pocket C (top-right, blocks (7,1)-(8,3)): warp 4 (ladder) + warp 3 (ROUTE_2
-  door).
-
-So the traversal is: `(3,33)` -> ladder `(5,31)` -> emerge `(17,33)` -> walk the
-long cave to `(3,3)` -> ladder -> emerge `(17,3)` -> door `(15,5)` -> Route 2
-`(12,7)`. That is exactly the FAQ's "down the ladder, ride up, up that ladder,
-exit the door".

-  `npctrade TRADE_DIALOGSET_HAPPY, GLOOM, RAPIDASH, "RUNNY", $96, $66,
-  BURNT_BERRY, 15616, "CHRIS", TRADE_GENDER_EITHER` - the player gives GLOOM and
-  receives a RAPIDASH nicknamed RUNNY, DVs `$96/$66`, holding a BURNT_BERRY, OT

-## 4. Bot checklist
-
-Coordinates are asm cell coordinates. "clear" / "set" refer to event flags.
-
-1. `ROUTE_19_FUCHSIA_GATE` -> `ROUTE_19`: walk warp 3/4 at (4,7)/(5,7).
-   Precondition: none. Expect to be stopped; `EVENT_CINNABAR_ROCKS_CLEARED` is
-   clear, so blocks `(6,6) (8,6) (10,6) (12,8) (4,8) (10,10)` are rock. Turn
-   around through warp 1 at (7,3).
-2. FLY to `VERMILION_CITY`. Precondition: `ENGINE_FLYPOINT_VERMILION` set.
-3. Open the Pokegear, RADIO card, tune the knob to 78 ("20.0"). Precondition:
-   `POKEGEAR_EXPN_CARD_F` set and the landmark is Kanto. Postcondition:
-   `wMapMusic == MUSIC_POKE_FLUTE_CHANNEL`.
-4. Close the Pokegear and walk to one of (33,8) / (34,10) / (35,10) / (36,8) /

-## 6. Unresolved / verify by hand
-
- **Brock's party order.** The FAQ lists Graveler, Omastar, Rhyhorn, Onix,
-  Kabutops. `data/trainers/parties.asm:270` `BrockGroup` is Graveler (41),
-  **Rhyhorn (41), Omastar (42)**, Onix (44), Kabutops (42) - slots 2 and 3 are
-  swapped relative to the FAQ. Levels and species set match.
- **All the FAQ's prize money figures are exactly 4x the asm value.**
-  `ComputeTrainerReward` (`engine/battle/read_trainer_party.asm:300`) is
-  `base reward x last mon level`, with no multiplier. Brock 25 x 42 = 1050 (FAQ
-  says 4,200); Rob 4 x 32 = 128 (FAQ 512); Doug 4 x 34 = 136 (FAQ 544); Ed
-  4 x 30 = 120 (FAQ 480); Jerry 5 x 37 = 185 (FAQ 740). The FAQ's EXP figures
-  likewise do not come from GS. Treat the money/EXP numbers in this section as
-  belonging to a different game (most likely HeartGold/SoulSilver, which the
-  text references) and ignore them for a GS bot.
- **"Viridian Forest".** The FAQ says the Max Potion is "in Viridian Forest".
-  There is no Viridian Forest map in `constants/map_constants.asm`; the
-  MAX_POTION is `ROUTE2_POKE_BALL2` at (2,23) on `ROUTE_2`, in the area the
-  forest used to occupy.
- **"the man just to the right of the Pokemart".** `PEWTERCITY_GRAMPS` spawns at
-  (29,17) with a `WALK_LEFT_RIGHT` radius of 2 (so x 27..31); the mart door is
-  warp 3 at (23,17). He is to the right of the mart but not adjacent.
- **"The Pokemon Center has a lady".** The trade NPC is `Chris`, sprite
-  `SPRITE_POKEFAN_M` at (7,2). Male sprite, name CHRIS.
- **Which cut tree the FAQ means.** The two trees named in step 14 and step 17
-  above are inferred from the block dump of `maps/Route2.blk` plus the item/warp
-  positions; they are not labelled anywhere in asm. Three other `CUT_TREE`
-  blocks exist on Route 2 (see the cut-tree table) and one of those may be the
-  intended route instead. Verify with a real walk.
- **Diglett's Cave pocket connectivity.** The three-pocket reading is derived by
-  hand from `maps/DiglettsCave.blk` block ids against
-  `data/tilesets/kanto_collision.asm`; the per-tile collision of the "long cave"
-  interior was not fully traced, only that every warp block is reachable within
-  its pocket. The FAQ's described route is consistent with it.
- **"the route is cleared to Diglett's Cave and through Route 8".** Nothing in
-  `maps/VermilionCity.asm` or `maps/Route11.asm` gates Route 11 / Route 8 on the
-  Snorlax; the only thing `EVENT_FOUGHT_SNORLAX` unlocks outside Vermilion is the
-  right-hand Black Belt object in `maps/VictoryRoadGate.asm:119`. The Snorlax
-  blocks only the Diglett's Cave door tile at (34,7).
- **"Keep around those four Ultra Balls"** and the Rest/Thunder Wave catch
-  advice are strategy, not asm; nothing enforces a ball count.
- **`src/world/gen2/Bike.lua` CAVE permission.** Marked partial in section 5 -
-  the port file was read but the equivalent of `BikeFunction.CheckEnvironment`
-  (`engine/events/overworld.asm:1665`) was not located, so "you can bike through
-  Diglett's Cave in the port" is unverified.

-## 1. Route order
-
-The walkthrough opens on the Magnet Train back to Johto - that hop belongs to the
-neighbouring Kanto section, and the only thing this section needs from it is that
-the player already holds the version-opposite wing.

-**Gold branch (Lugia, Whirl Islands)**

-
-Note the sight ranges: Kara is `4`, the widest on the route, which is why the
-walkthrough uses her as the landmark for the northeast whirlpool ("the whirlpool
-is just northwest of where you fought Swimmer Kara"). Her object sits at
-`(44, 28)`; the trainer flag is `EVENT_BEAT_SWIMMERF_KARA`, so once beaten she is
-still standing there (`event flag` on the row is `-1`, i.e. never masked) and
-still walks into your path - the walkthrough's joke about swimmer stamina is
-literally the object table.
-
-**Scripts of interest**
-
- `TrainerSwimmerfKara` - `trainer SWIMMERF, KARA, EVENT_BEAT_SWIMMERF_KARA, ...`.
-  Post-battle it only prints `SwimmerfKaraAfterBattleText` ("I heard roars from
-  deep inside the ISLANDS"). No flag beyond the beat flag, no gate.
-
-**Whirlpools**: they are *map blocks*, not events. `data/collision/field_move_blocks.asm:48-55`
-gives `WhirlpoolBlockPointers` -> `TILESET_JOHTO` -> `db $07, $36, 0` (facing
-block `$07`, replacement `$36`, animation type 0). A bot that wants the whirlpool
-coordinates has to scan `maps/Route41.blk` for block id `$07`; the collision
-value under it is `COLL_WHIRLPOOL` `$24` (`constants/collision_constants.asm:27`,
-tested by `CheckWhirlpoolTile`, `home/map_objects.asm:176-183`).
-
-**Wild encounters**
-
- Surfing, `data/wild/johto_water.asm:170-181`, `def_water_wildmons ROUTE_41`,
-  encounter rate `6 percent`. Gold: `20 TENTACOOL`, `20 TENTACRUEL`, `20 MANTINE`.
-  Silver: `20 TENTACOOL`, `20 TENTACRUEL`, `15 TENTACOOL`.
- Fishing: header fish group is `FISHGROUP_OCEAN` (`data/wild/fish.asm:13`,
-  `.Ocean_Old/.Ocean_Good/.Ocean_Super`).
- The walkthrough's Max Repel advice is aimed squarely at this 6% table.

-**Scripts of interest**
-
- `WhirlIslandLugiaChamberLugiaCallback` - `callback MAPCALLBACK_OBJECTS`.
-  `checkevent EVENT_FOUGHT_LUGIA / iftrue .NoAppear`, then
-  `checkitem SILVER_WING / iftrue .Appear`, else `.NoAppear`. So Lugia is on the
-  map **only while the SILVER_WING is in the bag and the fight has not happened**.
-  The wing is a `checkitem`, not an event - selling or storing it makes Lugia
-  vanish again.
- `Lugia` (`47:41a0`) - `faceplayer`, `opentext`, `writetext LugiaText`
-  ("Gyaaas!"), `cry LUGIA`, `pause 15`, `closetext`,
-  **`setevent EVENT_FOUGHT_LUGIA`**, `checkver`, `iftrue .Silver`.
-  - Gold arm: `loadvar VAR_BATTLETYPE, BATTLETYPE_FORCEITEM`,
-    `loadwildmon LUGIA, 70`, `startbattle`,
-    `disappear WHIRLISLANDLUGIACHAMBER_LUGIA`, `reloadmapafterbattle`, `end`.
-  - `.Silver`: identical but `loadwildmon LUGIA, 40`.
-  - `EVENT_FOUGHT_LUGIA` is set **before** the battle, so fleeing, fainting or
-    knocking it out all consume the encounter. This is exactly why the
-    walkthrough insists on saving first: there is no re-arm path in the asm.
-  - `BATTLETYPE_FORCEITEM` (`constants/battle_constants.asm:101`) makes
-    `InitEnemyMon`'s `.WildItem` arm hand over `wBaseItem1` unconditionally
-    (`engine/battle/core.asm:5765-5773`). Lugia's `data/pokemon/base_stats/lugia.asm`
-    row is `db NO_ITEM, NO_ITEM`, so it holds nothing - the forced-item type is
-    inherited boilerplate here.

-**Flags and events**
-
-| constant | defined in | read/written by | meaning for a bot |
-|---|---|---|---|
-| `EVENT_FOUGHT_LUGIA` | `constants/event_flags.asm:455` | read by the callback, set by `Lugia` before `startbattle` | one-shot. Once set, Lugia never reappears |
-| `EVENT_WHIRL_ISLAND_LUGIA_CHAMBER_LUGIA` | `constants/event_flags.asm:1247` | the object row's mask flag, driven by `appear`/`disappear` | object visibility only |
-| `EVENT_GOT_SILVER_WING` | `constants/event_flags.asm:130` | set by `PewterCityGrampsScript` (Gold) / `RadioTower5F` (Silver) | prerequisite for holding `SILVER_WING` |
-
-**Wild encounters**
-
- Floor: `data/wild/johto_grass.asm:1269-1295`, rate `6 percent`:
-  `24 KRABBY`, `25 ZUBAT`, `26 KRABBY`, `24 SEEL`, `25 GOLBAT`, `26 SEEL`, `26 SEEL`.
- Water: `data/wild/johto_water.asm:93-98`, rate `4 percent`: `20 HORSEA`,
-  `20 TENTACRUEL`, `20 SEADRA`. This is the only Seadra slot in the dungeon, and
-  it is on the water directly in front of Lugia.
-
-**Catch math** (`data/pokemon/base_stats/lugia.asm`): `db 3 ; catch rate`.
-`UltraBallMultiplier` doubles it to 6; `HeavyBallMultiplier`
-(`engine/items/item_effects.asm:752`) adds a flat offset by dex weight, and
-Lugia's dex weight is `4760` tenths of a pound = 216 kg
-(`data/pokemon/dex_entries/gold/lugia.asm`), which lands in the `+20` bracket ->
-effective 23. Thard_Verad's tip in the FAQ is correct and is worth ~4x the Ultra
-Ball rate.

-
-Warps 3 and 4 are a self-referential pair: the map holds two disconnected

-
-Scene ids come from the `scene_script` macro's inline `const` block

-
-Object rows are masked when their flag is **set** (`CheckObjectFlag`,
-`engine/overworld/map_objects_2.asm:32-61`: `EventFlagAction`/`CHECK_FLAG`
-non-zero -> `.masked`). `InitializeEventsScript`
-(`engine/events/std_scripts.asm:438`, line 533) does
-`setevent EVENT_ECRUTEAK_TIN_TOWER_ENTRANCE_SAGE_LEFT` at new game, so on a fresh
-save only SAGE2 at `(5, 6)` is standing there.
-
-**Scripts of interest**
-
- `EcruteakTinTowerEntranceSageScript` - `faceplayer`, `opentext`,
-  `checkflag ENGINE_FOGBADGE`, `iftrue .BlockPassage_GotFogBadge`. Both arms are
-  pure text (`EcruteakTinTowerEntranceSageText` vs `..._GotFogBadge`); **the
-  script never opens the path**.
- The actual unblock is `maps/EcruteakGym.asm:34`:
-  `setmapscene ECRUTEAK_TIN_TOWER_ENTRANCE, SCENE_ECRUTEAKTINTOWERENTRANCE_NOOP`,
-  run in the same block as `setflag ENGINE_FOGBADGE` after beating Morty. With
-  the scene at `NOOP` the two coord events no longer match and the sage never
-  steps into the doorway. By section 25 the player has all 16 badges, so this is
-  already open - the walkthrough's "talk to the man and he'll let you through" is
-  flavour text, not a required action.
- `EcruteakTinTowerEntranceWanderingSageScript` - `checkevent EVENT_GOT_RAINBOW_WING`;
-  the post-wing line is "The TIN TOWER shook! A #MON must have returned to the
-  top!". This is the only in-map confirmation that Ho-Oh is now spawnable.

-
-**This is the real gate for the whole Silver branch.** The sage's coordinates are
-`(10, 2)`, byte-for-byte the coordinates of warp 3. While the object is visible
-the stair tile is occupied and 2F is unreachable. The object is masked - i.e. the
-sage disappears - when `EVENT_TEAM_ROCKET_DISBANDED`
-(`constants/event_flags.asm:1283`) is **set**, and that flag is only ever set by
-the two Rainbow Wing hand-offs:
-
- `maps/RadioTower5F.asm:124-130` (Gold): `verbosegiveitem RAINBOW_WING` (124),
-  `setevent EVENT_GOT_RAINBOW_WING` (129), `setevent EVENT_TEAM_ROCKET_DISBANDED` (130).
- `maps/PewterCity.asm:42-51` `.RainbowWing` (Silver): the gramps gives
-  `RAINBOW_WING` (49), `setevent EVENT_GOT_RAINBOW_WING` (50),
-  `setevent EVENT_TEAM_ROCKET_DISBANDED` (51).
-
-So the walkthrough's "another bald man will let you through because you have the
-beautiful Rainbow Wing" is literally true, but the mechanism is a masked object
-keyed on `EVENT_TEAM_ROCKET_DISBANDED`, not a `checkitem RAINBOW_WING`.
-
-**Wild encounters**: none - `TIN_TOWER_1F` has no `def_grass_wildmons` row
-(`data/wild/johto_grass.asm` starts the tower at `TIN_TOWER_2F`, line 61).

-| `TINTOWERROOF_HO_OH` | `SPRITE_HO_OH` | 9 | 5 | `SPRITEMOVEDATA_POKEMON` | `OBJECTTYPE_SCRIPT`, palette `PAL_NPC_RED` | `TinTowerHoOh` | `EVENT_TIN_TOWER_ROOF_HO_OH` |
-
-**Scripts of interest**
-
- `TinTowerRoofHoOhCallback` - `callback MAPCALLBACK_OBJECTS`:
-  `checkevent EVENT_FOUGHT_HO_OH / iftrue .NoAppear`, then
-  `checkitem RAINBOW_WING / iftrue .Appear`. Same shape as Lugia's: the wing must
-  be **in the bag**, not merely once-received.
- `TinTowerHoOh` (`5b:6913`) - text "Shaoooh!", `cry HO_OH`, `pause 15`,
-  `setevent EVENT_FOUGHT_HO_OH` **before** the fight, `checkver / iftrue .Silver`.
-  - Gold arm: `loadwildmon HO_OH, 40`.
-  - `.Silver`: `loadwildmon HO_OH, 70` - the level the walkthrough quotes.
-  - Both arms run `loadvar VAR_BATTLETYPE, BATTLETYPE_FORCEITEM` first, and
-    Ho-Oh's base row is `db SACRED_ASH, SACRED_ASH`
-    (`data/pokemon/base_stats/ho_oh.asm:9`), so **Ho-Oh always holds a SACRED_ASH**.
-    That is a guaranteed item a bot should strip before/after the catch.
-
-**Escape Rope caveat**: `EscapeRopeFunction` -> `.CheckCanDig`
-(`engine/events/overworld.asm:724-754`) only succeeds when
-`GetMapEnvironment` is `CAVE` or `DUNGEON`. `TIN_TOWER_ROOF` is `ROUTE`, so the
-walkthrough is right that you must go back down to 9F first. Every Whirl Island
-map including `WHIRL_ISLAND_LUGIA_CHAMBER` is `CAVE`, so the rope works on the
-spot there.
-
-**Catch math**: Ho-Oh's catch rate is also `3`
-(`data/pokemon/base_stats/ho_oh.asm:7`). Its dex weight is `4390`
-(`data/pokemon/dex_entries/gold/ho_oh.asm`) = 199 kg, which falls in the
-`HeavyBallMultiplier` "add 0" bracket - so unlike Lugia, a Heavy Ball is *worse*
-than an Ultra Ball on Ho-Oh.

-## 3. Blockers and gates
-
-| Gate | Enforced by (file:label) | Requirement | Unlock condition |
-|---|---|---|---|
-| Reaching Route 41 at all | `SurfFunction.TrySurf`, `engine/events/overworld.asm:322` (badge test at `:340`) | `ENGINE_FOGBADGE` + a party member that knows `SURF` | Fog Badge (Morty) |
-| Whirlpools guarding the Whirl Islands | `WhirlpoolFunction` `engine/events/overworld.asm:1061` (badge test at `:1077`) and `TryWhirlpoolOW` `:1167` (badge test at `:1171`) | `ENGINE_GLACIERBADGE` + `WHIRLPOOL` in the party | Glacier Badge (Pryce, badge 7) - **not** eight badges, see Unresolved |
-| Darkness inside every Whirl Island map | `FlashFunction.CheckUseFlash`, `engine/events/overworld.asm:271` | `ENGINE_ZEPHYRBADGE` + `FLASH`, and `wTimeOfDayPalset == DARKNESS_PALSET` (the map header's `PALETTE_DARK`) | Zephyr Badge. Flash is *refused* on any non-dark map, so a bot must only try it inside |
-| Climbing back up the B2F waterfall | `WaterfallFunction` `engine/events/overworld.asm:611` (badge test at `:618`) and `TryWaterfallOW` `:683` (badge test at `:687`); direction check `CheckMapCanWaterfall` (must face UP, `wTileUp` is a waterfall tile) | `ENGINE_RISINGBADGE` + `WATERFALL` | Rising Badge (Clair). Descending needs nothing - only the UP direction is gated |
-| B1F boulder at `(23, 26)` | `WhirlIslandB1FBoulder` -> `jumpstd StrengthBoulderScript` | `STRENGTH` + `ENGINE_PLAINBADGE` | optional; not on the Lugia path |
-| Lugia not on the map | `WhirlIslandLugiaChamberLugiaCallback` | `checkitem SILVER_WING` true **and** `EVENT_FOUGHT_LUGIA` clear | `EVENT_GOT_SILVER_WING` via `PewterCityGrampsScript` (Gold) or `RadioTower5F` (Silver) - and keep the wing in the bag |
-| Ho-Oh not on the map | `TinTowerRoofHoOhCallback` | `checkitem RAINBOW_WING` true **and** `EVENT_FOUGHT_HO_OH` clear | `EVENT_GOT_RAINBOW_WING` via `RadioTower5F` (Gold) or `PewterCityGrampsScript` `.RainbowWing` (Silver) |
-| Tin Tower stairs to 2F | `TinTower1F` object row: sage stands on `(10, 2)`, masked by `EVENT_TEAM_ROCKET_DISBANDED` | flag must be **set** | `setevent EVENT_TEAM_ROCKET_DISBANDED` in `maps/RadioTower5F.asm:130` or `maps/PewterCity.asm:51` |
-| Tin Tower entrance corridor | `coord_event 4, 7` / `5, 7` under `SCENE_ECRUTEAKTINTOWERENTRANCE_SAGE_BLOCKS` | scene must be `NOOP` | `maps/EcruteakGym.asm:34` `setmapscene ... SCENE_ECRUTEAKTINTOWERENTRANCE_NOOP` on the Fog Badge |
-| One-shot mascot | `Lugia` / `TinTowerHoOh` set `EVENT_FOUGHT_LUGIA` / `EVENT_FOUGHT_HO_OH` **before** `startbattle` | n/a | none. Save-before-fight is the only recovery |

-## 5. Port coverage
-
-| Beat | Port file | Status |
-|---|---|---|
-| Map headers, warps, coord/bg/object events for all of these maps | `src/import/RomExtractorGen2.lua` (walks all 26 map groups, `MAP_GROUP_COUNT` at line 47), consumed by `src/world/gen2/Map.lua` / `World.lua` | implemented (generic - no map-specific code, so these maps come in with everything else) |
-| `MAPCALLBACK_OBJECTS` (the Lugia / Ho-Oh appear-check) | `src/world/gen2/World.lua:5700` `runMapCallback("MAPCALLBACK_OBJECTS")`; regression driver `tests/drivers/gold_map_callbacks.lua` | implemented |
-| Object masking by event flag (`CheckObjectFlag`) - the Tin Tower 1F sage, every item ball | `src/world/gen2/World.lua:5106,5122` `events:objectVisible(obj.eventFlag)` | implemented |
-| `checkver` version split (Lv70 vs Lv40 mascot) | `src/script/gen2/Vm.lua:774-783`; opcode table `src/script/gen2/Opcodes.lua:29` | implemented (comments even cite `WhirlIslandLugiaChamber` by name) |
-| `loadwildmon` / `startbattle` / `reloadmapafterbattle` | `src/script/gen2/Opcodes.lua:98-101`, `src/script/gen2/Vm.lua:817-896` | implemented |
-| `BATTLETYPE_FORCEITEM` -> Ho-Oh's guaranteed `SACRED_ASH` | `src/world/gen2/World.lua:107-111` and `:4571-4579` | implemented |
-| Whirlpool field move, badge gate and block replacement | `src/world/gen2/FieldMoves.lua:109` (`WHIRLPOOL = "GLACIER"`), `:219` `WHIRLPOOL_BLOCKS`, `:247` `somethingToWhirlpool`, `:542` `whirlpoolFromMenu`, `:626` `tryWhirlpoolOW` | implemented |
-| Flash + `PALETTE_DARK` darkness | `src/world/gen2/FieldMoves.lua:105,468`; `src/world/gen2/Palettes.lua:53,75-103` | implemented |
-| Waterfall (up-only gate, `RISINGBADGE`) | `src/world/gen2/FieldMoves.lua:110,258,646` | implemented |
-| Hidden items (`hiddenitem` bg events) | `src/world/gen2/HiddenItems.lua`, `src/world/gen2/World.lua:1373,5286` | implemented |
-| Catch rate formula incl. the two cart bugs | `src/battle/gen2/Catching.lua:1-90` | implemented |
-| **Heavy Ball weight bonus** (the FAQ's Lugia tip) | `src/battle/gen2/Catching.lua:36` - `HEAVY_BALL = 1`, a flat multiplier with a comment saying the specialty balls "key off conditions the caller supplies", and no dex-weight lookup anywhere | **missing** - a Heavy Ball currently behaves as a plain Poke Ball on Lugia |
-| Magnet Train hop that opens the section | `src/core/gen2/MagnetTrain.lua` | implemented (not re-verified for this section) |
-| Escape Rope environment check (`CAVE`/`DUNGEON` only, roof excluded) | not located in `src/world/gen2/` or `src/battle/gen2/` by grep | **unverified** - could not find an `EscapeRopeFunction` equivalent; a bot should not assume the roof refusal is modelled |
-| Hand-ported scripts for these specific maps | none - grep for `whirl`/`tintower`/`lugia`/`hooh` across `src/` returns only battle-anim and title-screen hits | not applicable (all script bodies are extracted, run through `src/script/gen2/Vm.lua`) |

-
-## 6. Unresolved / verify by hand
-
-1. **"You'll need eight badges in order to use Whirlpool."** The asm gates
-   Whirlpool on `ENGINE_GLACIERBADGE` alone (`engine/events/overworld.asm:1077`
-   and `:1171`), i.e. seven badges. Eight is wrong, though harmless in practice
-   for a post-game section.
-2. **Whirl Islands item list.** The FAQ lists Calcium, Escape Rope, Guard Specs,
-   Max Revive x2, Ultra Ball. The asm has *one* Max Revive in the entire dungeon
-   (`WhirlIslandB2FMaxRevive` at B2F `(6, 4)`) and additionally a `FULL_RESTORE`,
-   `CARBOS`, `NUGGET` on B1F, a second `FULL_RESTORE` and a `MAX_ELIXER` on B2F,
-   plus three hidden items on B1F that the FAQ never mentions. The walkthrough's
-   two "grab the Max Revive" beats cannot both be the B2F ball; the first one is
-   unlocatable.
-3. **Tin Tower item list.** The FAQ names a PP Up, an HP Up, a Max Potion item
-   ball, and a second Full Heal. None exist in pokegold: there is no `PP_UP` or
-   `HP_UP` anywhere in `maps/TinTower*.asm`, the only Max Potion is the *hidden*
-   `TinTower4FHiddenMaxPotion` at `(11, 6)`, and the only Full Heal is
-   `TinTower3FFullHeal`. Conversely the FAQ omits `SUPER_POTION` (4F),
-   `NUGGET`/`FULL_RESTORE` (8F) and the three hidden items on 4F/5F. The list
-   looks like it was written against a different version of the game.
-4. **"On the next level, go up and you'll get a Max Potion ... Full Heal"** places
-   two items on the 6F-shaped floor; `maps/TinTower6F.asm` has an empty
-   `def_bg_events` and an empty `def_object_events`. Not locatable.
-5. **Ho-Oh's moveset.** The FAQ says "Safeguard and Ancient Power ..., Punishment,
-   and Sacred Fire". `PUNISHMENT` does not exist in Gen 2 at all
-   (`data/pokemon/evos_attacks.asm:3324-3336` is the whole learnset). Derived
-   from that table plus `FillMoves` (`engine/pokemon/evolve.asm:478`, which keeps
-   the last four moves learnable at or below the level), a level-70 Ho-Oh should
-   have `RECOVER`, `FIRE_BLAST`, `SUNNY_DAY`, `SWIFT`, and a level-40 one
-   `SACRED_FIRE`, `SAFEGUARD`, `GUST`, `RECOVER`. Worth confirming in-engine
-   before a bot plans around Sacred Fire; the `FillMoves` derivation is mine, not
-   a literal table in the asm.
-6. **Lugia's Pokemon list at the Whirl Islands.** The FAQ lists Zubat, Seel,
-   Krabby, Horsea, Seadra and omits `GOLBAT` (in every grass slot 5),
-   `TENTACOOL` / `TENTACRUEL` (SW and B2F water). Seadra only appears in
-   `WHIRL_ISLAND_LUGIA_CHAMBER`'s water table.
-7. **"Swimmer Kara" as a whirlpool landmark.** Her object is at `(44, 28)` on
-   Route 41; the whirlpool "just northwest" of her is a `.blk` block, not an
-   event, so the exact coordinate could not be pinned from the asm text. A bot
-   must scan `maps/Route41.blk` for `TILESET_JOHTO` block `$07`.
-8. **The Whirl Islands ledge/jump routing** ("leap the ledge to the right on that
-   bike", "two items on the cliff but you can't reach those") is entirely block
-   and collision data in `maps/WhirlIsland*.blk`. None of it is expressible from
-   the event tables; a bot needs the decoded block/collision grid.
-9. **The Tin Tower jump-platform routing** (the long "left x5, down, right x2 ..."
-   sequences) is likewise `.blk` data. Only the warp endpoints above are asm
-   facts.
-10. **"go into the Bell Tower entry house"** - the map, the sign and every text
-    string in pokegold call it TIN TOWER (`TinTowerSign`,
-    `EcruteakTinTowerEntranceSageText`). "Bell Tower" is the post-GS rename.
-11. **Escape Rope on the port.** Could not find the port's equivalent of
-    `EscapeRopeFunction`'s `CAVE`/`DUNGEON` environment check, so I cannot say
-    whether the port correctly refuses the rope on `TIN_TOWER_ROOF`.

-### MAP_ROUTE_3
-
- Script: `maps/Route3.asm` (`Route3_MapEvents` = `50:514b`)
- Blocks: `maps/Route3.blk`
- Header: `data/maps/maps.asm:321` -> `map Route3, TILESET_KANTO, ROUTE, LANDMARK_ROUTE_3, MUSIC_ROUTE_3, FALSE, PALETTE_AUTO, FISHGROUP_SHORE`
- Dimensions: `constants/map_constants.asm:296` -> `map_const ROUTE_3, 30, 9` (30x9 blocks = 60x18 walk cells), group `PEWTER`
- Connections: `data/maps/attributes.asm:377` -> west `PewterCity` (offset -5), east `Route4` (offset 0). No north/south.
- Scene scripts: none (`def_scene_scripts` is empty). Callbacks: none.

-Column order comes from `macros/scripts/maps.asm:113` (`object_event x, y, sprite, movement, radius_x, radius_y, hour1, hour2, palette, type, sight_range, script, event_flag`). All four here have radius 0/0 and hour limits `-1, -1` (always present).
-
-**Scripts of interest**
-
- `TrainerFirebreatherOtis` / `TrainerYoungsterWarren` / `TrainerYoungsterJimmy` / `TrainerFirebreatherBurt`: each is a plain `trainer CLASS, ID, EVENT_BEAT_*, SeenText, BeatenText, 0, .Script` header. `.Script` is `endifjustbattled / opentext / writetext <After>Text / waitbutton / closetext / end`. No items, no flags beyond the trainer's own beaten flag, no warps.
-
-**Flags and events**
-
-| constant | defined in | read/written by | meaning for a bot |
-|---|---|---|---|
-| `EVENT_BEAT_FIREBREATHER_OTIS` | `constants/event_flags.asm:576` | `trainer` header | set on win; trainer will not re-challenge |

-
-All four are `TRAINERTYPE_NORMAL`, i.e. level+species only, moves come from the learnset.
-
-**Wild encounters**
-
-`data/wild/kanto_grass.asm:314` `def_grass_wildmons ROUTE_3`, rates `10 percent, 10 percent, 10 percent` (morn/day/nite). The table is version-split:
-
- `IF DEF(_GOLD)` - morn/day: L5 SPEAROW, L5 RATTATA, L8 SPEAROW, L6 JIGGLYPUFF, L10 RATTATA, L8 SPEAROW, L8 SPEAROW; nite: L5 RATTATA, L5 ZUBAT, L8 RATTATA, L6 JIGGLYPUFF, L10 RATTATA, L8 RATTATA, L8 RATTATA.
- `ELIF DEF(_SILVER)` - morn/day: L5 SPEAROW, L5 RATTATA, L8 EKANS, L6 JIGGLYPUFF, L10 ARBOK, L8 SPEAROW, L8 SPEAROW; nite: L5 RATTATA, L5 ZUBAT, L8 EKANS, L6 JIGGLYPUFF, L10 ARBOK, L8 RATTATA, L8 RATTATA.
-
-The walkthrough's "Rattata / Ekans / Arbok" is the **Silver** column. On Gold there is no Ekans or Arbok on Route 3. See section 6.
-
-No water/fishing/headbutt entry for `ROUTE_3` in `data/wild/kanto_water.asm` or `data/wild/treemons.asm`.

-
-### MAP_MOUNT_MOON
-
- Script: `maps/MountMoon.asm` (`MountMoon_MapEvents` = `42:587e`, `MountMoonRivalBattleScript` = `42:55b0`)
- Blocks: `maps/MountMoon.blk`
- Header: `data/maps/maps.asm:154` -> `map MountMoon, TILESET_CAVE, CAVE, LANDMARK_MT_MOON, MUSIC_MT_MOON, TRUE, PALETTE_NITE, FISHGROUP_SHORE` (the `TRUE` column is the phone/"requires flash-style" fixed palette flag position in the `map` macro; palette is `PALETTE_NITE`, so the cave is dark-toned regardless of clock)
- Dimensions: `constants/map_constants.asm:141` -> `map_const MOUNT_MOON, 15, 9` (15x9 blocks = 30x18 walk cells), group `CERULEAN`-adjacent index 76 in its group listing
- Attributes: `data/maps/attributes.asm:488` -> `map_attributes MountMoon, MOUNT_MOON, $09`. **No connections** - the map is entered and left only through warps.
- Scene var: `data/maps/scenes.asm:46` -> `wMountMoonSceneID`
-
-**Scene scripts** (`def_scene_scripts`, ids allocated from 0 by `macros/scripts/maps.asm:12`)
-
-| scene id | constant | script |
-|---|---|---|
-| 0 | `SCENE_MOUNTMOON_RIVAL_BATTLE` | `MountMoonRivalEncounterScene` -> `sdefer MountMoonRivalBattleScript` |
-| 1 | `SCENE_MOUNTMOON_NOOP` | `MountMoonNoopScene` -> `end` |
-
-Nothing in the game sets scene 0; it is the power-on default, so the very first entry to Mt. Moon fires the rival cutscene. `RunSceneScript` is polled in `engine/overworld/events.asm:256`, after `CheckTrainerEvent` and `CheckTileEvent`, so it lands on the first player-event poll after the warp completes.
-
-**Callbacks**: none.
-
-**Warps** (`def_warp_events`)
-
-| idx | x | y | destination map | dest warp |
-|---|---|---|---|---|
-| 1 | 3 | 3 | `ROUTE_3` | 1 |

-| 3 | 13 | 3 | `MOUNT_MOON` | 7 |

-| 8 | 25 | 13 | `MOUNT_MOON` | 4 |
-
-Warps 3<->7 and 4<->8 are the two internal ladder pairs. Read as a graph:
-`ROUTE_3 -(1)- (3,3) ... (13,3) -(3/7)- (25,3) ... (25,5) -(5)- SQUARE`
-and `SQUARE -(2/6)- (25,15) ... (25,13) -(8/4)- (15,11) ... (15,15) -(2)- ROUTE_4`.
-
-**Coord events**: none. **BG events**: none.
-
-**Object events**
-
-| const | sprite | x | y | movement | type | script label | event flag |
-|---|---|---|---|---|---|---|---|
-| `MOUNTMOON_RIVAL` | `SPRITE_RIVAL` | 7 | 3 | `SPRITEMOVEDATA_STANDING_LEFT` | `OBJECTTYPE_SCRIPT`, sight 0 | `ObjectEvent` (the shared ROM0 stub) | `EVENT_MT_MOON_RIVAL` |
-
-Flag semantics (`engine/overworld/scripting.asm:879-898`): `appear` clears the object's event flag, `disappear` sets it. `EVENT_MT_MOON_RIVAL` therefore starts **clear** = rival visible, and `disappear MOUNTMOON_RIVAL` at the end of the cutscene sets it = rival gone forever.
-
-**Scripts of interest**
-
-`MountMoonRivalBattleScript` (`42:55b0`), reached through `sdefer` from scene 0:
-
-1. `turnobject PLAYER, RIGHT`, `showemote EMOTE_SHOCK, PLAYER, 15`, `special FadeOutMusic`, `pause 15`.
-2. `applymovement MOUNTMOON_RIVAL, MountMoonRivalMovementBefore` = three `step LEFT` (rival walks from (7,3) toward the player at the (3,3) entrance).
-3. `playmusic MUSIC_RIVAL_ENCOUNTER`, `opentext`, `writetext MountMoonRivalTextBefore`, `waitbutton`, `closetext`.
-4. Starter branch:
-   - `checkevent EVENT_GOT_TOTODILE_FROM_ELM` -> `.Totodile` -> `loadtrainer RIVAL2, RIVAL2_1_CHIKORITA`
-   - `checkevent EVENT_GOT_CHIKORITA_FROM_ELM` -> `.Chikorita` -> `loadtrainer RIVAL2, RIVAL2_1_CYNDAQUIL`
-   - fallthrough (player took Cyndaquil) -> `loadtrainer RIVAL2, RIVAL2_1_TOTODILE`
-   Note the label names describe the *player's* starter; the constant names describe the *rival's*. Each arm does `winlosstext MountMoonRivalTextWin, MountMoonRivalTextLoss`, `setlasttalked MOUNTMOON_RIVAL`, `startbattle`, `dontrestartmapmusic`, `reloadmapafterbattle`.
-5. `.FinishBattle`: `playmusic MUSIC_RIVAL_AFTER`, after-text, `turnobject PLAYER, UP`, `turnobject PLAYER, RIGHT`, `applymovement MOUNTMOON_RIVAL, MountMoonRivalMovementAfter` (`RIGHT, RIGHT, DOWN x5`), `disappear MOUNTMOON_RIVAL`, `setscene SCENE_MOUNTMOON_NOOP`, `setevent EVENT_BEAT_RIVAL_IN_MT_MOON`, `playmapmusic`, `end`.
-
-The battle is unavoidable: there is no `iftrue` skip and no branch that reaches the rest of the map without running it, because the scene id is 0 until `setscene` runs at the very end of the script.

-
-| constant | defined in | read/written by | meaning for a bot |

-
-`TRAINERTYPE_MOVES`, so the four move slots above are exactly what the rival fields. `RIVAL2_2_*` (rows 4-6, levels 45-50 with Crobat) are the Indigo Plateau rematch parties, not this fight.

-**Wild encounters**
-
-`data/wild/kanto_grass.asm:33` `def_grass_wildmons MOUNT_MOON`, rates `6 percent, 6 percent, 6 percent`.

- `ELIF DEF(_SILVER)` - L6 ZUBAT, L8 GEODUDE, L8 ZUBAT, L12 PARAS, L10 GEODUDE, L8 CLEFAIRY, L8 CLEFAIRY.
-
-The walkthrough's "Zubat / Parus [sic, Paras] / Geodude" is a subset of both columns. Gold additionally has Sandshrew and Sandslash, and both versions have a 2-slot Clefairy line the walkthrough does not mention.

-
-**Callbacks**
-
- `MAPCALLBACK_NEWMAP` -> `MountMoonSquareDisappearMoonStoneCallback`: `setevent EVENT_MOUNT_MOON_SQUARE_HIDDEN_MOON_STONE` / `endcallback`. Every fresh entry re-hides the Moon Stone.
- `MAPCALLBACK_OBJECTS` -> `MountMoonSquareDisappearRockCallback`: `disappear MOUNTMOONSQUARE_ROCK` / `endcallback`. The smashable rock is hidden on every object refresh; it exists on-screen only during the dance cutscene, which `appear`s it mid-script.

-
-**Scripts of interest**
-
-`ClefairyDance` - the whole cutscene is guarded by three conditions in a row, all of which must pass:
-
-```
-checkflag ENGINE_MT_MOON_SQUARE_CLEFAIRY   ; iftrue .NoDancing  (once per save)
-readvar VAR_WEEKDAY / ifnotequal MONDAY, .NoDancing
-checktime NITE / iffalse .NoDancing
-```
-
-Then: `appear` both fairies, `applymovement PLAYER, PlayerWalksUpToDancingClefairies` (one `step UP`, so the player ends on (7, 10)), `pause 15`, `appear MOUNTMOONSQUARE_ROCK`, a long `follow`/`applymovement`/`cry CLEFAIRY` dance across `ClefairyDanceStep1..7`, `showemote EMOTE_SHOCK` when the Clefairy notice the player, `applymovement ... ClefairyFleeMovement`, `disappear` both fairies, `stopfollow`, then the payoff:
-
-```
-clearevent EVENT_MOUNT_MOON_SQUARE_HIDDEN_MOON_STONE
-setflag ENGINE_MT_MOON_SQUARE_CLEFAIRY
-```
-
-So the Moon Stone at bg_event (7, 7) becomes takeable, but the rock object was `appear`ed onto that exact cell during the cutscene and is only cleared by `MAPCALLBACK_OBJECTS` on the next map load. That is the asm behind Thard_Verad's "Bring Rock Smash": you either smash the rock at (7, 7) in the same visit, or leave and come back (the `MAPCALLBACK_NEWMAP` callback then re-sets the Moon Stone flag and re-hides the item, so leaving loses it). See section 6.
-
-`MtMoonSquareRock` -> `jumpstd SmashRockScript` (`engine/events/std_scripts.asm:199`) -> `farsjump AskRockSmashScript` (`engine/events/overworld.asm:1365`), which is `callasm HasRockSmash` (`engine/events/overworld.asm:1386`: `ld d, ROCK_SMASH / call CheckPartyMove`) then a yes/no prompt. **No badge check** - Rock Smash in Gen 2 is TM08, not an HM.

-All three trainer scripts are the standard `endifjustbattled / opentext / writetext <After>Text / waitbutton / closetext / end`. `Route4HPUp` is not bytecode at all - `itemball HP_UP` is two raw bytes (`macros/scripts/maps.asm`, `dwb`-style), read by the engine's item-ball path rather than the script VM.

-`CAL, CAL2` is the only trainer in the game whose party is **not** read from `data/trainers/parties.asm`: `engine/battle/read_trainer_party.asm:17-22` branches to `.cal2` and reads `sMysteryGiftTrainer` out of SRAM, and `GetTrainerName` (same file, line 326) reads `sMysteryGiftPartnerName`.

-6. `ROUTE_3` - optional: read the sign at (49, 13). Then heal (walkthrough advice, no flag) and save.
-7. `ROUTE_3` - step on warp 1 at (52, 1). Postcondition: player on `MOUNT_MOON` at (3, 3).
-8. `MOUNT_MOON` - do nothing; the scene script fires. Precondition: `wMountMoonSceneID == 0`, `EVENT_MT_MOON_RIVAL` clear. Intent: battle `RIVAL2` with the party chosen by `EVENT_GOT_TOTODILE_FROM_ELM` / `EVENT_GOT_CHIKORITA_FROM_ELM`. Postcondition: `EVENT_BEAT_RIVAL_IN_MT_MOON` set, `EVENT_MT_MOON_RIVAL` set, `wMountMoonSceneID = 1`.
-9. Optional detour: `MOUNT_MOON` (13, 3) warp 3 -> lands at (25, 3); walk to (25, 5) warp 5 -> `MOUNT_MOON_SQUARE` (20, 5).
-10. `MOUNT_MOON_SQUARE` - (13, 7) warp 3 -> `MOUNT_MOON_GIFT_SHOP`. Talk to the clerk (`(4, 3)` in MORN, `(1, 2)` in DAY - **no clerk at NITE**) to open `MART_MT_MOON`. Exit at (3, 7) or (4, 7).
-11. `MOUNT_MOON_SQUARE` optional, Monday night only: walk onto (7, 11) to trip `ClefairyDance`. Preconditions: `ENGINE_MT_MOON_SQUARE_CLEFAIRY` clear, `VAR_WEEKDAY == MONDAY`, `checktime NITE` true. Postcondition: `ENGINE_MT_MOON_SQUARE_CLEFAIRY` set, `EVENT_MOUNT_MOON_SQUARE_HIDDEN_MOON_STONE` cleared. Then, **without leaving the map**, face (7, 7); if the rock object is there, use Rock Smash (requires `ROCK_SMASH` in the party), then press A on (7, 7) to take `MOON_STONE`.
-12. `MOUNT_MOON_SQUARE` - (22, 11) warp 2 -> `MOUNT_MOON` (25, 15). Walk to (25, 13) warp 8 -> lands at (15, 11). Walk to (15, 15) warp 2 -> `ROUTE_4` (2, 5).

-17. `ROUTE_4` - optional hidden item: face (10, 3), press A -> `ULTRA_BALL`. Post: `EVENT_ROUTE_4_HIDDEN_ULTRA_BALL`.
-18. Travel to `VIRIDIAN_CITY` (Fly needs `ENGINE_STORMBADGE` and the destination flypoint; the walkthrough's route is Fly to Pewter, then `ROUTE_2` south through `VIRIDIAN_FOREST`). Entering Viridian sets `ENGINE_FLYPOINT_VIRIDIAN`.
-19. `VIRIDIAN_CITY` - optional: talk to `VIRIDIANCITY_FISHER` at (6, 23) for `TM_DREAM_EATER`. Precondition: `EVENT_GOT_TM42_DREAM_EATER` clear and pack room. Post: set.
-20. `VIRIDIAN_CITY` - warp 3 at (23, 15) -> `TRAINER_HOUSE_1F` (2, 13). Then warp 3 at (8, 2) -> `TRAINER_HOUSE_B1F` (9, 4).

-## 5. Port coverage
-
-| Beat | Port file | Status |
-|---|---|---|
-| Kanto map geometry, warps, connections, bg/coord/object rows | `src/import/RomExtractorGen2.lua` (extracts all map events), `src/world/gen2/Map.lua`, `src/world/gen2/World.lua` | implemented (generic - every map in the ROM comes through the same path, no per-map Kanto code needed) |
-| Scene scripts / `wMapSceneID` (Mt. Moon rival, Trainer House coord_event) | `src/world/gen2/World.lua:1175-1183` (`GetMapSceneID` port), `:5014-5040` (coord event and scene script lookup) | implemented |
-| `sdefer` timing for the Mt. Moon rival cutscene | `src/script/gen2/Vm.lua:92-93` | partial - the comment says "sdefer queues after the map settles in retail; run immediately here", so the rival scene starts a frame or two earlier than the cart. Cosmetic for a bot, visible in a screenshot diff. |
-| Map callbacks (`MAPCALLBACK_NEWMAP` / `MAPCALLBACK_OBJECTS`) - the flypoint setters and the Mt. Moon Square rock/moon-stone callbacks | `src/world/gen2/World.lua:5969`, driver `tests/drivers/gold_map_callbacks.lua` | implemented, with an assertion driver |
-| `appear` / `disappear` object visibility via the event bitfield | `src/world/gen2/Events.lua` (header comment cites `CheckObjectFlag`) | implemented |
-| Overworld trainers: `trainer` struct, eyesight, party build | `src/world/gen2/Trainers.lua`, `src/world/gen2/World.lua:5257-5264`, driver `tests/drivers/gold_trainer_smoke.lua` | implemented |
-| `loadtrainer` / `startbattle` / `winlosstext` / `setlasttalked` (the rival and CAL fights) | `src/script/gen2/Opcodes.lua:99,100,105,109`, `src/script/gen2/Vm.lua:806` | implemented |
-| Trainer House daily CAL battle + Mystery Gift fallback | `src/world/gen2/TrainerHouse.lua` | implemented (deliberately answers `CAL3`; Mystery Gift is out of scope, documented in the file header) |
-| Cutscene opcodes used by `ClefairyDance` and the rival scene: `showemote`, `follow`, `stopfollow`, `cry`, `moveobject`, `applymovement` | `src/script/gen2/Opcodes.lua:117-137`, `src/script/gen2/Vm.lua:961`, `src/script/gen2/Movement.lua` | implemented |
-| `checktime` / `VAR_WEEKDAY` (the Monday-night Clefairy guard) | `src/script/gen2/Vm.lua:784`, `src/core/gen2/BugContest.lua:112` (`weekday`) | implemented |
-| Hidden items (`BGEVENT_ITEM`: Mt. Moon Square Moon Stone, Route 4 Ultra Ball) | `src/world/gen2/HiddenItems.lua`, wired at `src/world/gen2/World.lua:5291` | implemented |
-| Item balls (`OBJECTTYPE_ITEMBALL`: the Route 4 HP Up) | extracted at `src/import/RomExtractorGen2.lua:2968-2969` as `obj.itemball`; **nothing reads it** - `World:interact` (`src/world/gen2/World.lua:5257`) only dispatches `npc.def.trainer`, strength boulders, `npc.def.scriptKey`, bg events and hidden items | **missing** - a bot cannot pick up the Route 4 HP Up in this port today |
-| Fruit trees (`fruittree FRUITTREE_ROUTE_1` -> Bitter Berry) | `src/core/gen2/Apricorns.lua` (`FruitTreeItems` table, per-tree flag, `tryResetFruitTrees`), `src/script/gen2/Vm.lua:1191` | implemented |
-| `pokemart` / `MART_MT_MOON` | `src/script/gen2/Vm.lua:597`, `src/ui/gen2/MartMenu.lua:336-348` | implemented (list comes from the extracted `data/generated/marts.lua`) |
-| `verbosegiveitem` (Viridian TM42) | `src/script/gen2/Vm.lua:490-498` | implemented |
-| Rock Smash on the Mt. Moon Square rock | `src/world/gen2/FieldMoves.lua` (comment at :588 lists `ROCK_SMASH` among the field moves); the strength-boulder equivalent is special-cased in `World:interact` | partial - `jumpstd SmashRockScript` is a `farsjump` into ASM, so there is no bytecode for the extractor to find. `World:interact` has an explicit arm for strength boulders (`World.isStrengthBoulder`) but **no equivalent arm for `SPRITEMOVEDATA_SMASHABLE_ROCK`**, so pressing A on the Mt. Moon Square rock reaches a nil `scriptKey`. Verify by hand. |
-| Fly / flypoints (`ENGINE_FLYPOINT_PALLET` = 52, `ENGINE_FLYPOINT_VIRIDIAN` = 53) | `src/world/gen2/FieldMoves.lua:342-370` (both Kanto rows present) | implemented |
-| Kanto wild tables (Gold vs Silver split) | extracted by `src/import/RomExtractorGen2.lua` from the ROM, so whichever cart was imported is what you get | implemented (no version conditional needed - the ROM already picked) |
-

-
-## 6. Unresolved / verify by hand
-
-1. **Rival party order contradicts the walkthrough.** The walkthrough lists Sneasel, Golbat, *Starter Evolution*, Magneton, Gengar, Alakazam. `data/trainers/parties.asm:2042-2069` lists Sneasel(41), Golbat(42), Magneton(41), Gengar(43), Alakazam(43), **starter last at level 45**. The walkthrough's per-mon strategy text is still correct; only the ordering is wrong. Levels and species otherwise match.
-2. **Route 3 and Route 4 wild lists in the walkthrough are the Silver tables.** `data/wild/kanto_grass.asm:314` and `:369` both have `IF DEF(_GOLD) / ELIF DEF(_SILVER)` arms. Ekans and Arbok only exist in the `_SILVER` arm. On Gold, Route 3 is Spearow/Rattata/Jigglypuff (+Zubat at nite) and Route 4 is the same. The walkthrough is titled for Gold but quoted the Silver data.
-3. **Mt. Moon wild list is incomplete in the walkthrough.** Gold also has L8 SANDSHREW, L10 SANDSLASH and two L8 CLEFAIRY slots (`data/wild/kanto_grass.asm:33`). The Clefairy slots mean Clefairy can be caught in the cave at any time, independent of the Monday-night dance.
-4. **Route 1 wild list is incomplete and time-dependent.** The walkthrough lists Pidgey and Furret; the nite column (`data/wild/kanto_grass.asm:250`) has neither - it is Hoothoot and Rattata only.
-5. **"Bitter Berry" on Route 1 is a fruit tree, not a ground item.** `Route1FruitTree` = `fruittree FRUITTREE_ROUTE_1`, and `data/items/fruit_trees.asm` row `ROUTE_1` is `BITTER_BERRY`. It respawns daily rather than being a one-time pickup, which the walkthrough's "Item on Route 1" phrasing implies.
-6. **The two Mt. Moon routes described in the walkthrough could not be verified against the collision map.** The warp graph in section 2 is exact, but which of warps 2/3/4 are reachable from the (3, 3) entrance without passing through the Square depends on `maps/MountMoon.blk` collision, which was not decoded here. The walkthrough's "either way, you end up in the same spot" is consistent with warps 4<->8 and 6 meeting on the (25, 13)/(25, 15) side, but confirm by walking it.
-7. **"Bring Rock Smash" for the Clefairy Moon Stone.** The asm supports the claim indirectly: `MountMoonSquareDisappearRockCallback` hides `MOUNTMOONSQUARE_ROCK` on every `MAPCALLBACK_OBJECTS`, `ClefairyDance` `appear`s it at (7, 7) mid-cutscene, and (7, 7) is exactly the `BGEVENT_ITEM` tile the dance unlocks. Whether the rock actually blocks the tile-facing A press (as opposed to being walkable) was not verified; the item could also be reachable by facing (7, 7) from an adjacent cell. Verify in-game.
-8. **`ULTRA_BALL` at Route 4 (10, 3) and `TM_DREAM_EATER` in Viridian are absent from the walkthrough.** Both are real (`maps/Route4.asm` bg_event, `maps/ViridianCity.asm` `ViridianCityDreamEaterFisher`). Not a contradiction, just an omission worth carrying into a completionist route.
-9. **Mt. Moon Gift Shop has no NITE clerk.** Both `SPRITE_GRAMPS` rows are gated `-1, MORN` and `-1, DAY`. A bot that arrives at night finds no shop, which the walkthrough does not warn about.
-10. **`ROUTE_3` warp position vs. its sign.** The only warp is at (52, 1) but the "MT.MOON SQUARE / Just go up the stairs" sign is at (49, 13), twelve cells south. That is what the file says; it reads oddly and is worth an eyeball on the rendered map.
-11. **Port: `OBJECTTYPE_ITEMBALL` pickup is unimplemented** (see section 5). The Route 4 HP Up is the first item ball this section needs, and `World:interact` has no arm for it. Confirmed by reading `src/world/gen2/World.lua:5257-5310` and grepping the whole `src/` tree for `itemball` (only the extractor and one comment in `src/script/gen2/CallAsm.lua:547` mention it).
-12. **Port: smashable-rock objects have no interact arm** (see section 5). Same class of gap as the item ball, but lower stakes because the only rock in this section is optional.

-  `trainer SWIMMERF, NIKKI, EVENT_BEAT_SWIMMERF_NIKKI, SwimmerfNikkiSeenText, SwimmerfNikkiBeatenText, 0, .Script`.
-  The `0` is the loss-text slot (no whiteout text). `.Script` is `endifjustbattled` +
-  one after-battle line; no items, no flags beyond the beat flag.
- `TrainerFisherArnold` (`maps/Route21.asm:33`, sym `4e:4817`) - same shape,

-
-There are no scene scripts and no callbacks on this map (`def_scene_scripts` /
-`def_callbacks` at `maps/Route21.asm:7-9` are both empty).

-### MAP_CINNABAR_ISLAND
-
- Script: `maps/CinnabarIsland.asm`
- Blocks: `maps/CinnabarIsland.blk`
- Header: `data/maps/maps.asm:199` -> `TILESET_KANTO, TOWN, LANDMARK_CINNABAR_ISLAND, MUSIC_VIRIDIAN_CITY, FALSE, PALETTE_AUTO, FISHGROUP_OCEAN`

- Fly / respawn point: `data/maps/flypoints.asm:28` `db LANDMARK_CINNABAR_ISLAND, SPAWN_CINNABAR`;

-
-**Warps** (`def_warp_events`, `maps/CinnabarIsland.asm:131-132`)

-
-**Coord events** (`def_coord_events`)
-
-None (`maps/CinnabarIsland.asm:134`). Blue is a talk-to NPC, not a trip-wire.
-
-**BG events** (`def_bg_events`, `maps/CinnabarIsland.asm:136-140`)
-
-| x | y | type | script/item |
-|---|---|---|---|

-| 9 | 11 | `BGEVENT_READ` | `CinnabarIslandGymSign` -> "CINNABAR GYM has relocated to SEAFOAM ISLANDS. BLAINE" |
-| 7 | 7 | `BGEVENT_READ` | `CinnabarIslandSign` -> town sign |
-| 9 | 1 | `BGEVENT_ITEM` | `CinnabarIslandHiddenRareCandy` -> `hiddenitem RARE_CANDY, EVENT_CINNABAR_ISLAND_HIDDEN_RARE_CANDY` (sym `4e:49a2`) |

-
-**Scripts of interest**
-
- `CinnabarIslandFlypointCallback` (`maps/CinnabarIsland.asm:10`, sym `4e:4981`), wired
-  as `callback MAPCALLBACK_NEWMAP` at `:8`. Body is exactly
-  `setflag ENGINE_FLYPOINT_CINNABAR` / `endcallback`. Walking in once is the whole
-  unlock for flying here.
- `CinnabarIslandBlue` (`maps/CinnabarIsland.asm:14`, sym `4e:4985`). Control flow, in
-  order: `faceplayer`, `opentext`, `writetext CinnabarIslandBlueText`, `waitbutton`,
-  `closetext`, `playsound SFX_WARP_TO`,
-  `applymovement CINNABARISLAND_BLUE, CinnabarIslandBlueTeleport`,
-  `disappear CINNABARISLAND_BLUE`, `clearevent EVENT_VIRIDIAN_GYM_BLUE`, `end`.
-  - There is **no guard flag and no `iftrue`** at the top: the script is one-shot only
-    because `disappear` sets the object's own `EVENT_BLUE_IN_CINNABAR` (see
-    `Script_disappear` at `engine/overworld/scripting.asm:887`, `ld b, 1 ; set`).
-  - `CinnabarIslandBlueTeleport` (`:38`) is a two-byte movement stream:
-    `teleport_from` (`$4c`, `macros/scripts/movement.asm:148`) then `step_end`. That is
-    the "levitates and flies off" the walkthrough describes.
-  - `clearevent EVENT_VIRIDIAN_GYM_BLUE` is the load-bearing side effect: that flag is
-    set at boot by `InitializeEventsScript` (`engine/events/std_scripts.asm:552`) and it
-    hides both `VIRIDIANGYM_BLUE` and the Viridian gym guide
-    (`maps/ViridianGym.asm:183-184`). **Talking to Blue here is the only thing that
-    puts Blue in Viridian Gym.**
- `CinnabarIslandHiddenRareCandy` (`maps/CinnabarIsland.asm:35`) - a `hiddenitem`
-  operand, not a script body: `dwb EVENT_CINNABAR_ISLAND_HIDDEN_RARE_CANDY, RARE_CANDY`.
-
-**Flags and events**
-
-| constant | defined in | read/written by | meaning for a bot |
-|---|---|---|---|
-| `ENGINE_FLYPOINT_CINNABAR` | `constants/engine_flags.asm:77` | set by `CinnabarIslandFlypointCallback` | Fly destination unlocked; also the wVisitedSpawns bit for respawn |
-| `EVENT_BLUE_IN_CINNABAR` | `constants/event_flags.asm:1303` | *set* implicitly by `disappear CINNABARISLAND_BLUE`; read by `maps/ViridianCity.asm:37` and `maps/ViridianPokecenter1F.asm:18` for "Blue returned" dialogue | clear = Blue is standing on Cinnabar; set = you have heard the speech |
-| `EVENT_VIRIDIAN_GYM_BLUE` | `constants/event_flags.asm:1304` | set at `engine/events/std_scripts.asm:552`; cleared by `CinnabarIslandBlue` | while set, Viridian Gym is empty |
-| `EVENT_CINNABAR_ISLAND_HIDDEN_RARE_CANDY` | `constants/event_flags.asm:254` | the `hiddenitem` at `maps/CinnabarIsland.asm:36` | one-shot guard on the hidden candy |
-
-Note: `EVENT_BLUE_IN_CINNABAR` is **not** in the `InitializeEventsScript` list, so it
-starts clear and Blue is visible from the first time you reach the island.
-
-**Items**
-
-| item | how obtained | source | one-time flag |
-|---|---|---|---|
-| `RARE_CANDY` | face tile (9,1) and press A (or ITEMFINDER) | `bg_event 9, 1, BGEVENT_ITEM, CinnabarIslandHiddenRareCandy` | `EVENT_CINNABAR_ISLAND_HIDDEN_RARE_CANDY` |
-
-The walkthrough never mentions this candy.
-
-**Trainers**
-
-None.
-
-**Wild encounters**
-
-No `def_grass_wildmons`/`def_water_wildmons` row for `CINNABAR_ISLAND` in
-`data/wild/kanto_grass.asm` or `data/wild/kanto_water.asm`. The surrounding water belongs
-to Route 20 / Route 21. Fishing on the map's own water uses `FISHGROUP_OCEAN`
-(`data/maps/maps.asm:199`).

-| `SEAFOAMGYM_BLAINE` | `SPRITE_BLAINE` | 5 | 2 | `SPRITEMOVEDATA_STANDING_DOWN` | `OBJECTTYPE_SCRIPT` | 0 | `SeafoamGymBlaineScript` | -1 (always present) |

-**Scripts of interest**
-
- `SeafoamGymBlaineScript` (`maps/SeafoamGym.asm:14`, sym `53:516d`). Control flow:
-  1. `faceplayer`, `opentext`
-  2. `checkflag ENGINE_VOLCANOBADGE` / `iftrue .FightDone` - the entire re-talk guard is
-     the badge engine flag, **not** an event flag.
-  3. `writetext BlaineIntroText`, `waitbutton`, `closetext`
-  4. `winlosstext BlaineWinLossText, 0` (no loss text)
-  5. `loadtrainer BLAINE, BLAINE1`, `startbattle`
-  6. `iftrue .ReturnAfterBattle` - i.e. if the battle result is non-zero (you lost /
-     drew) it *skips* `appear SEAFOAMGYM_GYM_GUIDE`
-  7. `appear SEAFOAMGYM_GYM_GUIDE` - clears `EVENT_SEAFOAM_GYM_GYM_GUIDE`, which is how
-     the guide "comes in late"
-  8. `.ReturnAfterBattle`: `reloadmapafterbattle`, `setevent EVENT_BEAT_BLAINE`,
-     `opentext`, `writetext ReceivedVolcanoBadgeText`, `playsound SFX_GET_BADGE`,
-     `waitsfx`, **`setflag ENGINE_VOLCANOBADGE`**, `writetext BlaineAfterBattleText`,
-     `waitbutton`, `closetext`, `end`
-  - No `verbosegiveitem` anywhere: **Blaine gives no TM**, only the badge.
-  - Note the ordering quirk: `setevent EVENT_BEAT_BLAINE` / `setflag ENGINE_VOLCANOBADGE`
-    are on the shared `.ReturnAfterBattle` path, reached whether or not you won, but
-    `startbattle` does not return to the script on a whiteout, so in practice this is
-    only reached after a win.
- `SeafoamGymGuideScript` (`maps/SeafoamGym.asm:46`, sym `53:51a3`) - branches on
-  `EVENT_TALKED_TO_SEAFOAM_GYM_GUIDE_ONCE`, first line is the apology
-  ("CINNABAR GYM was gone, so I didn't know where to find you"), then a second line
-  forever after.
-
-**Flags and events**
-
-| constant | defined in | read/written by | meaning for a bot |
-|---|---|---|---|
-| `ENGINE_VOLCANOBADGE` | `constants/engine_flags.asm:53` (Kanto badge 7; `wKantoBadges` bit 6 per `constants/ram_constants.asm:270`) | checked at `maps/SeafoamGym.asm:17`, set at `:34` | the badge itself; also gates the re-talk branch |
-| `EVENT_BEAT_BLAINE` | `constants/event_flags.asm:721` | set at `maps/SeafoamGym.asm:29` | not read by any other map in the checkout; it is the record, not the gate |
-| `EVENT_SEAFOAM_GYM_GYM_GUIDE` | `constants/event_flags.asm:1305` | set at boot (`engine/events/std_scripts.asm:553`), cleared by `appear` at `maps/SeafoamGym.asm:26` | while set, the guide object does not exist |
-| `EVENT_TALKED_TO_SEAFOAM_GYM_GUIDE_ONCE` | `constants/event_flags.asm:212` | `maps/SeafoamGym.asm:49`, `:54` | first-talk vs repeat text |
-
-What VOLCANOBADGE actually does mechanically: `data/types/badge_type_boosts.asm:19`
-`db FIRE ; VOLCANOBADGE`, consumed by `DoBadgeTypeBoosts` (`engine/battle/misc.asm:146`,
-called from `engine/battle/effect_commands.asm:1261`) - a +12.5% damage boost on the
-player's FIRE-type moves. It grants no field move.
-
-**Items**
-
-None.
-
-**Trainers**
-
-| const | class | id | party (`data/trainers/parties.asm`) | script label | rematch/phone |
-|---|---|---|---|---|---|
-| `BLAINE, BLAINE1` | BLAINE ($2e), `constants/trainer_constants.asm:469-470` | 1 | `BlaineGroup` (sym `0e:6e70`) at `parties.asm:2303`, `TRAINERTYPE_MOVES`: **L45 MAGCARGO** (CURSE, SMOG, FLAMETHROWER, ROCK_SLIDE), **L45 MAGMAR** (THUNDERPUNCH, FIRE_PUNCH, SUNNY_DAY, CONFUSE_RAY), **L50 RAPIDASH** (QUICK_ATTACK, FIRE_SPIN, FURY_ATTACK, FIRE_BLAST) | `SeafoamGymBlaineScript` | no rematch, no phone |
-
-Class attributes (`data/trainers/attributes.asm:275-279`): AI items are
-**`MAX_POTION, FULL_HEAL`** (not two Full Restores); base reward 25; AI mask
-`AI_BASIC | AI_SETUP | AI_SMART | AI_AGGRESSIVE | AI_CAUTIOUS | AI_STATUS | AI_RISKY`,
-`CONTEXT_USE | SWITCH_SOMETIMES`. Payout 25 x 50 x 4 = **5000**, matching the walkthrough.
-`BLAINE` is in `KantoGymLeaders` (`data/trainers/leaders.asm`), so the battle uses the
-gym-leader music and awards `HAPPINESS_GYMBATTLE`.
-
-**Wild encounters**
-
-None. The map is `INDOOR` with `TILESET_CAVE`; its `FISHGROUP_SHORE` header entry is the
-default and has no reachable water.

-## 3. Blockers and gates
-
-| Gate | Enforced by (file:label) | Requirement | Unlock condition |
-|---|---|---|---|
-| Everything in this section is across open sea (Pallet -> Route 21 -> Cinnabar -> Route 20 -> gym door) | `engine/events/overworld.asm:469` `TrySurfOW` (walk-into-water path): `ld de, ENGINE_FOGBADGE` / `CheckEngineFlag` at `:490`, then `ld d, SURF` / `CheckPartyMove`. Menu path is `SurfFunction` `.TrySurf` at `:340` with the same `ENGINE_FOGBADGE`. `CheckBadge` itself is at `:50`. | FOGBADGE + a party mon that knows SURF | already held long before Kanto (Johto badge 4) |
-| Fly to Cinnabar Island | `data/maps/flypoints.asm:28`; the flag is `ENGINE_FLYPOINT_CINNABAR`, set by `CinnabarIslandFlypointCallback` (`maps/CinnabarIsland.asm:10`) | STORMBADGE + FLY + having stood on Cinnabar Island once | walk in once |
-| Blue is not in Viridian Gym | `maps/ViridianGym.asm:183-184` object rows carry `EVENT_VIRIDIAN_GYM_BLUE`, set at `engine/events/std_scripts.asm:552` | - | `clearevent EVENT_VIRIDIAN_GYM_BLUE` at the tail of `CinnabarIslandBlue` (`maps/CinnabarIsland.asm:23`) - **this section is a hard prerequisite for the Viridian Gym leader** |
-| Route 19 (east of Route 20) is sealed by six boulder blocks | `maps/Route19.asm:15` `Route19ClearRocksCallback`, a `MAPCALLBACK_TILES` callback that lays `changeblock` rock blocks while `EVENT_CINNABAR_ROCKS_CLEARED` is clear | - | `setevent EVENT_CINNABAR_ROCKS_CLEARED` in `Route20ClearRocksCallback` (`maps/Route20.asm:13`), i.e. simply loading Route 20 once from the Cinnabar side |
-| Blaine will not re-battle | `maps/SeafoamGym.asm:17` `checkflag ENGINE_VOLCANOBADGE` / `iftrue .FightDone` | - | none in vanilla; `.FightDone` is terminal |
-| The gym guide does not exist until Blaine is beaten | object row event flag `EVENT_SEAFOAM_GYM_GYM_GUIDE` (`maps/SeafoamGym.asm:170`), set at `engine/events/std_scripts.asm:553` | beat Blaine | `appear SEAFOAMGYM_GYM_GUIDE` (`maps/SeafoamGym.asm:26`), only on the win branch |
-
-Nothing in this section needs CUT, STRENGTH, WHIRLPOOL, WATERFALL, FLASH or a key item.
-
-## 4. Bot checklist
-
-Ordered, machine-actionable. `(g,m)` is `(map group, map id)` from
-`constants/map_constants.asm`. All coordinates are the raw asm map-event values.
-
-1. `PALLET_TOWN`: SURF south across the connection into `ROUTE_21 (6,7)`.
-   Pre: FOGBADGE + SURF in the party. Post: none.
-2. `ROUTE_21`: battle `TrainerSwimmerfNikki` at (11,16) - sight radius 3, so she will
-   trigger on approach. Party L28 SEEL x3 + L28 DEWGONG. Post: `EVENT_BEAT_SWIMMERF_NIKKI`, +560 money.
-3. `ROUTE_21`: battle `TrainerFisherArnold` at (14,22) - sight radius 1, faces up.
-   Party L34 TENTACRUEL. Post: `EVENT_BEAT_FISHER_ARNOLD`, +1360 money.
-4. `ROUTE_21`: surf west then south to `TrainerSwimmermSeth` at (2,30) - sight radius 4,
-   faces right. Party L29 QUAGSIRE / L29 OCTILLERY / L32 QUAGSIRE.
-   Post: `EVENT_BEAT_SWIMMERM_SETH`, +256 money.
-   (Both trainers are avoidable - all three are `OBJECTTYPE_TRAINER` with a finite sight
-   radius, none are on a coord event.)
-5. `ROUTE_21`: continue south across the connection into `CINNABAR_ISLAND (6,8)`.
-   Post: `MAPCALLBACK_NEWMAP` sets `ENGINE_FLYPOINT_CINNABAR`; respawn point becomes
-   `SPAWN_CINNABAR` = (11,12).
-6. `CINNABAR_ISLAND`: step on warp 1 at (11,11) -> `CINNABAR_POKECENTER_1F (6,1)`.
-   Talk to `CINNABARPOKECENTER1F_NURSE` at (3,1) to heal. Optional: the two flavour NPCs
-   at (7,6) and (2,4). Exit via warp 1/2 at (3,7)/(4,7).
-7. `CINNABAR_ISLAND`: optional - face (9,1) and press A for the hidden **RARE_CANDY**.
-   Pre: `EVENT_CINNABAR_ISLAND_HIDDEN_RARE_CANDY` clear + a free bag slot.
-   Post: flag set. (Not in the walkthrough.)
-8. `CINNABAR_ISLAND`: walk to `CINNABARISLAND_BLUE` at (9,6) and talk.
-   Pre: `EVENT_BLUE_IN_CINNABAR` clear. Expect a long `writetext` (about 13 pages of
-   `para` breaks - budget A presses accordingly), then `SFX_WARP_TO` + a `teleport_from`
-   movement, then the object vanishes.
-   Post: `EVENT_BLUE_IN_CINNABAR` set (via `disappear`), `EVENT_VIRIDIAN_GYM_BLUE`
-   **cleared**. Do not skip this step: it is the only unlock for the Viridian Gym leader.
-9. `CINNABAR_ISLAND`: optional signs at (12,11), (9,11), (7,7).
-10. `CINNABAR_ISLAND`: SURF east across the connection into `ROUTE_20 (6,6)`.
-    Post: `MAPCALLBACK_NEWMAP` sets `EVENT_CINNABAR_ROCKS_CLEARED` (silent; unseals
-    Route 19 for the next section).
-11. `ROUTE_20`: battle `TrainerSwimmermCameron` at (12,13) - sight radius 3.
-    Party L34 MARILL. Post: `EVENT_BEAT_SWIMMERM_CAMERON`, +272 money.
-12. `ROUTE_20`: optional sign at (37,11). Then step onto warp 1 at (38,7) ->
-    `SEAFOAM_GYM (6,4)`.
-13. `SEAFOAM_GYM`: walk to `SEAFOAMGYM_BLAINE` at (5,2) and talk.
-    Pre: `ENGINE_VOLCANOBADGE` clear (otherwise you get `.FightDone` only).
-    Battle: `loadtrainer BLAINE, BLAINE1` - L45 MAGCARGO / L45 MAGMAR / L50 RAPIDASH,
-    AI holds MAX_POTION + FULL_HEAL.
-    Post: `EVENT_BEAT_BLAINE` set, `EVENT_SEAFOAM_GYM_GYM_GUIDE` cleared (guide appears
-    at (6,5)), **`ENGINE_VOLCANOBADGE` set**, +5000 money. No TM, no item.
-14. `SEAFOAM_GYM`: optional - talk to `SEAFOAMGYM_GYM_GUIDE` at (6,5).
-    Post: `EVENT_TALKED_TO_SEAFOAM_GYM_GUIDE_ONCE`.
-15. `SEAFOAM_GYM`: exit via warp 1 at (5,5) back to `ROUTE_20` warp 1.
-
-Follow-up (next section): Route 20 continues east past Lori (45,13) and Nicole (52,8)
-into `ROUTE_19`, whose rock blocks are now gone because step 10 set
-`EVENT_CINNABAR_ROCKS_CLEARED`.
-
-## 5. Port coverage
-
-| Beat | Port file | Status |
-|---|---|---|
-| Kanto map headers, dimensions, connections, warp / coord / bg / object tables | `src/import/RomExtractorGen2.lua` (all 26 map groups, `MAP_GROUP_COUNT = 26` at `:47`, `MapGroupPointers` walk at `:728`) | implemented - fully data-driven, nothing Cinnabar-specific needed |
-| `MAPCALLBACK_NEWMAP` (`CinnabarIslandFlypointCallback`, `Route20ClearRocksCallback`) | `src/world/gen2/World.lua:5659` `self:runMapCallback("MAPCALLBACK_NEWMAP")`, in `HandleNewMap` order (`:5646`) | implemented; asserted end-to-end by `tests/drivers/gold_map_callbacks.lua` |
-| `MAPCALLBACK_TILES` + `changeblock` (the Route 19 rocks that this section unseals) | `src/world/gen2/World.lua:5662`; `changeblock` opcode at `src/script/gen2/Opcodes.lua:127` | implemented |
-| `setflag ENGINE_FLYPOINT_CINNABAR` -> flyable | `src/world/gen2/FieldMoves.lua:367` (`LANDMARK_CINNABAR_ISLAND` / `SPAWN_CINNABAR` / flag 62), `World:setEngineFlag` at `src/world/gen2/World.lua:1326` | implemented |
-| `checkevent` / `setevent` / `clearevent`, `checkflag` / `setflag` | `src/script/gen2/Vm.lua:187-229` | implemented - id-keyed stores, `engineFlags` kept separate from `wEventFlags` |
-| `appear` / `disappear` writing the object's event flag (Blue vanishing, the guide arriving) | `src/script/gen2/Opcodes.lua:115-116`, handled in `src/script/gen2/Vm.lua` | implemented |
-| Hidden item `BGEVENT_ITEM` (Cinnabar RARE_CANDY at 9,1) | `src/world/gen2/HiddenItems.lua` (`BGEVENT_ITEM = 7` at `:22`), extractor branch at `src/import/RomExtractorGen2.lua:2986` | implemented |
-| `loadtrainer` / `startbattle` / `winlosstext` / `reloadmapafterbattle` / `endifjustbattled` (the whole Blaine script) | `src/script/gen2/Vm.lua:806`, `:817`, `:886`, `:918` | implemented, incl. the `iftrue` on `wBattleResult` that guards `appear SEAFOAMGYM_GYM_GUIDE` |
-| Gym-leader battle music / victory music for BLAINE | `src/battle/gen2/BattleMusic.lua:21`, `src/battle/gen2/Battle.lua:82` (both list `BLAINE = true`) | implemented |
-| Prize money = base x last-mon level x 4 (560 / 1360 / 256 / 272 / 5000) | `src/battle/gen2/Prize.lua` (header documents `ComputeTrainerReward` and the `ld c, 4` loop; `Prize.reward`) | implemented, incl. the Mom's-savings split |
-| Trainer sight radii (3 / 4 / 1 on Route 21) | `src/world/gen2/Trainers.lua` | implemented |
-| SURF gate on FOGBADGE + party move | `src/world/gen2/FieldMoves.lua:106` (`SURF = "FOG"`), `:481` `surfFromMenu`, `:678` overworld path | implemented; driven by `tests/drivers/gold_water_moves.lua` |
-| Ocean wild/fish tables for Routes 20/21 | extracted by `src/import/RomExtractorGen2.lua`, consumed by `src/battle/gen2/Encounter.lua` | implemented - correct by construction from the ROM |
-| Radio "Place & Name" un-hiding BLAINE after the Kanto badge sweep | `src/ui/gen2/Pokegear.lua:172` (`PNP_HIDDEN`), `:178` `PNP_HIDDEN_BEAT_KANTO`, `:1265` | implemented |
-| `setflag ENGINE_VOLCANOBADGE` reaching the trainer card / `VAR_BADGES` count | `src/script/gen2/Vm.lua:208-229` writes `save.engineFlags[53]`; but `VAR_BADGES` (`src/world/gen2/World.lua:1243-1244`) counts `save.player.badges` + `save.player.kantoBadges`, and `src/ui/gen2/TrainerCard.lua:395` reads `player.badges`. Nothing in `src/` ever writes `player.kantoBadges` (only initialised at `src/core/gen2/Save.lua:119`). | **partial** - Blaine's own re-talk guard works (same `engineFlags` id is read back by `checkflag`), but the badge does not show on the trainer card and does not increment `VAR_BADGES` |
-| `BadgeTypeBoosts` (VOLCANOBADGE = +12.5% FIRE damage) | no Gen 2 implementation - `grep -rn "badge" src/battle/gen2/` returns nothing; the only badge-boost code is the Gen 1 `src/battle/Damage.lua:35` | **missing** |
-| `teleport_from` (`$4c`) movement for Blue's exit | `src/script/gen2/Movement.lua:22` `decodeByte` - `$4c` matches no family branch and falls through to `{ kind = "nop" }` | **partial** - Blue disappears with the sound but without the rise-and-vanish animation |
-| End-to-end driver coverage for this stretch | `tests/drivers/gold_*.lua` (25 drivers, all Johto: boot, walk, warp, trainer, ice path, roamers, ...) | **missing** - no Cinnabar / Route 20 / Route 21 / Seafoam Gym driver exists |
-
-## 6. Unresolved / verify by hand
-
- **Blaine's movesets in the walkthrough are not the pokegold movesets.** The FAQ
-  describes Magcargo with Yawn / Recover / Overheat, Magmar with Confuse Ray, and
-  Rapidash with Flare Blitz / Bounce. `data/trainers/parties.asm:2303-2308` gives
-  MAGCARGO (CURSE, SMOG, FLAMETHROWER, ROCK_SLIDE), MAGMAR (THUNDERPUNCH, FIRE_PUNCH,
-  SUNNY_DAY, CONFUSE_RAY) and RAPIDASH (QUICK_ATTACK, FIRE_SPIN, FURY_ATTACK,
-  FIRE_BLAST). Only CONFUSE_RAY overlaps; Overheat, Flare Blitz, Bounce and Yawn do not
-  exist in `constants/move_constants.asm` at all for this generation. **Species and
-  levels match exactly** (L45 / L45 / L50), so treat the strategy prose as written
-  against a different (modernised) build and the asm as authoritative.
- **"Blaine will have two Full Restores available."** `data/trainers/attributes.asm:276`
-  is `db MAX_POTION, FULL_HEAL`. Two different items, neither of them a Full Restore.
-  The count of *uses* is AI-driven, not a fixed two.
- **"You now have 15 badges!"** Nothing in the asm counts badges as an ordinal; Kanto
-  gyms have no enforced order (`ENGINE_VOLCANOBADGE` is one bit,
-  `constants/engine_flags.asm:53`). The 15 is walkthrough prose that assumes a specific
-  visiting order.
- **Route 21 wild list is abridged in the walkthrough.** The FAQ lists Tentacool and
-  Tangela. `data/wild/kanto_grass.asm:1005` also has **MR__MIME** in all three
-  time slots, and `data/wild/kanto_water.asm:61` also has **TENTACRUEL**. Route 20's
-  list is likewise incomplete (TENTACRUEL is there too).
- **"Surf south on Route 21 ... head way left then down."** The trainer coordinates
-  confirm the shape of the route (16 -> 22 -> 30, then far west), but the actual walkable
-  water path is block data in `maps/Route21.blk` and was not decoded here.
- **"You should see a small cave at the Seafoam Islands."** The only asm anchor is
-  `warp_event 38, 7` on `maps/Route20.asm:117` plus `bg_event 37, 11` for the gym sign.
-  The cave mouth graphic itself is block data in `maps/Route20.blk`; there is no
-  Seafoam Islands dungeon map in Gen 2 (`constants/map_constants.asm` has only
-  `SEAFOAM_GYM`), so the walkthrough's "Seafoam Islands" is a landmark name
-  (`data/maps/landmarks.asm:94` `LANDMARK_SEAFOAM_ISLANDS`) rather than a walkable
-  dungeon.
- **EXP figures.** The per-mon EXP numbers in the FAQ (600 for a L28 Seel, 1056 for a
-  L28 Dewgong, 1492 for a L34 Tentacruel) are consistent with the vanilla
-  `base_exp * level / 7` times the 1.5x trainer-battle bonus, but nothing in
-  `data/trainers/parties.asm` stores them and they still vary with participation, so
-  they are not reproducible from the asm as written. The **money** figures all reproduce
-  exactly and are recorded above.
- **`EVENT_BEAT_BLAINE` has no reader.** Grepping `maps/`, `data/`, `engine/`, `home/`
-  and `constants/` finds it only at its definition (`constants/event_flags.asm:721`) and
-  its single `setevent` (`maps/SeafoamGym.asm:29`). If the port needs a "Blaine beaten"
-  predicate for anything, `ENGINE_VOLCANOBADGE` is the flag the cart actually branches on.

-Badges / key milestones in this section: EARTHBADGE (`ENGINE_EARTHBADGE`) from Blue in Viridian Gym, `EVENT_BEAT_BLUE`, five optional Swimmer battles on Routes 19/20. This is the 16th badge, which is what `maps/OaksLab.asm` reads to open Mt. Silver in a later section.

-Coordinate convention reminder: `warp_event` / `coord_event` / `bg_event` / `object_event` all take `x, y` in map cell coordinates, 0-based from the top-left (`macros/scripts/maps.asm:63`, `:79`, `:97`, `:113`). A map that is `W, H` blocks is `2W, 2H` cells. `changeblock` also takes cell coordinates and halves them internally (`engine/overworld/scripting.asm:2030` `Script_changeblock`, `home/map.asm:2099` `GetBlockLocation`).

- `Route20ClearRocksCallback` (`maps/Route20.asm:12`, sym `4e:4cfa`): two opcodes, `setevent EVENT_CINNABAR_ROCKS_CLEARED` then `endcallback`. This is the single most load-bearing fact on this map: merely *entering* Route 20 for the first time permanently clears the Route 19 boulders. There is no other setter of that flag anywhere in `maps/`.
- The three trainer scripts are the stock pattern: `trainer <CLASS>, <ID>, <EVENT>, SeenText, BeatenText, 0, .Script`, and `.Script` is `endifjustbattled / opentext / writetext <AfterBattleText> / waitbutton / closetext / end`. No items, no flags beyond the trainer's own beat flag.

-Note for a bot: Tucker `(8, 23)` and Dawn `(9, 23)` both have sight range 0, so they never initiate a battle by line of sight. They must be talked to, which is exactly the walkthrough's "Talk to the guy for a battle" / "talk to the girl to battle her". Harold and Jerome have sight 3 and will pull the player in.

-Both objects carry `EVENT_VIRIDIAN_GYM_BLUE` as their event flag, so while that flag is **set** the gym is completely empty. `EVENT_VIRIDIAN_GYM_BLUE` is set by `InitializeEventsScript` at new game (`engine/events/std_scripts.asm:438`, the `setevent` on line 552) and is cleared only by `CinnabarIslandBlue`.
-
-**Scripts of interest**
-
- `ViridianGymBlueScript` (`maps/ViridianGym.asm:10`, sym `5f:4002`), the whole badge beat, in order:
-  1. `faceplayer` / `opentext`
-  2. `checkflag ENGINE_EARTHBADGE` / `iftrue .FightDone` (sym `5f:402d`) - repeat visits get `LeaderBlueEpilogueText` only
-  3. `writetext LeaderBlueBeforeText` / `waitbutton` / `closetext`
-  4. `winlosstext LeaderBlueWinText, 0` (loss text pointer 0 = use the default)
-  5. `loadtrainer BLUE, BLUE1` / `startbattle` / `reloadmapafterbattle`
-  6. `setevent EVENT_BEAT_BLUE`
-  7. `opentext` / `writetext Text_ReceivedEarthBadge` / `playsound SFX_GET_BADGE` / `waitsfx`
-  8. `setflag ENGINE_EARTHBADGE`
-  9. `writetext LeaderBlueAfterText` / `waitbutton` / `closetext` / `end`
-
-  No `verbosegiveitem`: unlike Johto leaders, the Kanto leaders in GSC hand out no TM. The badge itself is the only reward besides money.
- `ViridianGymGuideScript` (`maps/ViridianGym.asm:39`, sym `5f:4033`): `checkevent EVENT_BEAT_BLUE / iftrue .ViridianGymGuideWinScript`. Pure flavor, no `learnmove`, no items.
- `ViridianGymStatue` (`maps/ViridianGym.asm:55`, sym `5f:4047`): `checkflag ENGINE_EARTHBADGE / iftrue .Beaten`; before the badge, `jumpstd GymStatue1Script` (`engine/events/std_scripts.asm:638`), after it `gettrainername STRING_BUFFER_4, BLUE, BLUE1` then `jumpstd GymStatue2Script` (`:646`). A cheap read-back a bot can use to confirm the badge landed.
-
-**Flags and events**
-
-| constant | defined in | read/written by | meaning for a bot |
-|---|---|---|---|
-| `ENGINE_EARTHBADGE` | `constants/engine_flags.asm:54` (in `wKantoBadges`) | read by `ViridianGymBlueScript` and `ViridianGymStatue`; set by `ViridianGymBlueScript` | The 16th badge. Post-condition of this section |
-| `EVENT_BEAT_BLUE` | `constants/event_flags.asm:722` | set by `ViridianGymBlueScript`, read by `ViridianGymGuideScript` | Set *before* the badge flag, between `reloadmapafterbattle` and `playsound` |
-| `EVENT_VIRIDIAN_GYM_BLUE` | `constants/event_flags.asm:1304` | set by `InitializeEventsScript` (`engine/events/std_scripts.asm:552`); cleared by `CinnabarIslandBlue` (`maps/CinnabarIsland.asm:23`) | While set, both gym objects are absent. This is the real gate on the whole section |
-| `EVENT_BLUE_IN_CINNABAR` | `constants/event_flags.asm:1303` | object flag of `CINNABARISLAND_BLUE` (`maps/CinnabarIsland.asm:143`), set by that script's `disappear` | Once set, Blue is gone from Cinnabar and (necessarily) present in the gym |
-
-**Items** - none. No item balls, no `hiddenitem`, no TM reward.
-
-**Trainers**
-
-| const | class | id | party (`data/trainers/parties.asm` label) | script label | rematch/phone |
-|---|---|---|---|---|---|
-| `BLUE` / `BLUE1` | 40 (`constants/trainer_constants.asm:640`) | `BLUE1` (`:641`) | `data/trainers/parties.asm:3154` `BlueGroup` (sym `0e:75ff`), `TRAINERTYPE_MOVES` | `ViridianGymBlueScript` | none (no phone entry; the map header's phone column is `TRUE` but no `phone_call` targets him) |
-
-`BlueGroup` party, verbatim:
-
-| # | level | species | moves |
-|---|---|---|---|
-| 1 | 56 | PIDGEOT | QUICK_ATTACK, WHIRLWIND, WING_ATTACK, MIRROR_MOVE |
-| 2 | 54 | ALAKAZAM | DISABLE, RECOVER, PSYCHIC_M, REFLECT |
-| 3 | 56 | RHYDON | FURY_ATTACK, SANDSTORM, ROCK_SLIDE, EARTHQUAKE |
-| 4 | 58 | GYARADOS | TWISTER, HYDRO_PUMP, RAIN_DANCE, HYPER_BEAM |
-| 5 | 58 | EXEGGUTOR | SUNNY_DAY, LEECH_SEED, EGG_BOMB, SOLARBEAM |
-| 6 | 58 | ARCANINE | ROAR, SWIFT, FLAMETHROWER, EXTREMESPEED |
-
-Class attributes (`data/trainers/attributes.asm:383`): items `FULL_RESTORE, FULL_RESTORE` (the AI will use two Full Restores), base reward 25, AI `AI_BASIC | AI_SETUP | AI_SMART | AI_AGGRESSIVE | AI_CAUTIOUS | AI_STATUS | AI_RISKY`, `CONTEXT_USE | SWITCH_SOMETIMES`. Payout `4 x 25 x 58 = 5800`, matching the FAQ. `BLUE` is listed in `KantoGymLeaders` (`data/trainers/leaders.asm:31`), which is what selects the gym-leader battle/victory music and awards `HAPPINESS_GYMBATTLE`.
-
-Walkthrough claims worth flagging against the party data: Pidgeot's flying move is `WING_ATTACK`, not Air Slash (which does not exist in Gen 2); Exeggutor's moves are `SUNNY_DAY, LEECH_SEED, EGG_BOMB, SOLARBEAM`, so it has neither Psychic nor Hypnosis; Arcanine's switch move is `ROAR`, Pidgeot's is `WHIRLWIND`.
-
-**Wild encounters** - none (indoor map).

-## 3. Blockers and gates
-
-| Gate | Enforced by (file:label) | Requirement | Unlock condition |
-|---|---|---|---|
-| Reaching Routes 19/20 at all | `engine/events/overworld.asm:322` `SurfFunction` -> `.TrySurf` (`ld de, ENGINE_FOGBADGE / call CheckBadge`), and the tile-facing path `engine/events/overworld.asm:469` `TrySurfOW` (`ENGINE_FOGBADGE` via `CheckEngineFlag`, then `CheckPartyMove` for `SURF`) | FOGBADGE + a party member knowing SURF | Both routes are open water; without Surf there is no approach |
-| Boulders across northern Route 19 | `maps/Route19.asm:15` `Route19ClearRocksCallback`, six `changeblock ..., $7a` under `checkevent EVENT_CINNABAR_ROCKS_CLEARED`; block `$7a` is `WALL` on all four quadrants (`data/tilesets/kanto_collision.asm:123`) | `EVENT_CINNABAR_ROCKS_CLEARED` | Set unconditionally by `maps/Route20.asm:12` `Route20ClearRocksCallback` on `MAPCALLBACK_NEWMAP`, i.e. by setting foot on Route 20 |
-| Blue is not in the Viridian Gym | Object event flag `EVENT_VIRIDIAN_GYM_BLUE` on both `maps/ViridianGym.asm:183-184` objects; set at new game by `engine/events/std_scripts.asm:552` inside `InitializeEventsScript` | Flag must be **clear** | `maps/CinnabarIsland.asm:14` `CinnabarIslandBlue`: talk to Blue on Cinnabar Island; the script runs `disappear CINNABARISLAND_BLUE` (setting `EVENT_BLUE_IN_CINNABAR`) then `clearevent EVENT_VIRIDIAN_GYM_BLUE`. This happens in an earlier section, but a bot that skipped it will find an empty gym |
-| Flying to Viridian City | `maps/ViridianCity.asm:13` `ViridianCityFlypointCallback` (`setflag ENGINE_FLYPOINT_VIRIDIAN`), plus `engine/events/overworld.asm:529` `FlyFunction` (`ld de, ENGINE_STORMBADGE`) and the landmark row `data/maps/flypoints.asm:19` | STORMBADGE + a party member knowing FLY + Viridian visited once on foot | Walk into Viridian City once (Route 1 north, Route 2 south, or Route 22 east). Otherwise reach the gym overland |
-| Re-fighting Blue | `maps/ViridianGym.asm:13` `checkflag ENGINE_EARTHBADGE / iftrue .FightDone` | - | Not possible; the battle is one-shot and there is no rematch or phone entry |
-| (Next section) Mt. Silver | `maps/OaksLab.asm:26` `readvar VAR_BADGES / ifequal NUM_BADGES, .OpenMtSilver` -> `setevent EVENT_OPENED_MT_SILVER` | All 16 badges, EARTHBADGE last | Beating Blue here is what satisfies it |
-
-Note on the Route 19 approach: the officer in `maps/Route19FuchsiaGate.asm` never blocks a tile, and `maps/Route19.asm` has no coord events. There is no NPC blocker anywhere in this section - every obstacle is either terrain (`changeblock`) or a hidden object (`EVENT_VIRIDIAN_GYM_BLUE`).
-
-## 4. Bot checklist
-
-Preconditions for the whole section: `ENGINE_FOGBADGE` + SURF in party, `EVENT_VIRIDIAN_GYM_BLUE` clear, `ENGINE_FLYPOINT_VIRIDIAN` set (or an overland plan to Viridian).

-
-## 5. Port coverage
-
-| Beat | Port file | Status |
-|---|---|---|
-| Map header, blocks, warps, coord/bg/object events for all six maps | `src/import/RomExtractorGen2.lua:782` `readMapEvents`, `:899` (map assembly) | implemented - the tables are read out of the ROM generically, so no per-map data is hand-written |
-| `MAPCALLBACK_NEWMAP` / `MAPCALLBACK_TILES` dispatch (needed for both rock callbacks and the Viridian fly point) | `src/world/gen2/World.lua:5659`, `:5664` | implemented |
-| `changeblock` (Route 19 boulders) | `src/script/gen2/Vm.lua:1002` (halves x/y to block coords, calls `changeBlockFn`) | implemented |
-| `setevent` / `clearevent` / `checkevent`, object-event hide flags | `src/world/gen2/Events.lua`, `src/script/gen2/Vm.lua` | implemented |
-| `setflag` / `checkflag` on `ENGINE_*` (EARTHBADGE, FLYPOINT_VIRIDIAN) | `src/script/gen2/Vm.lua:212-223`, `:1584` | implemented |
-| Surf field move + FOGBADGE check | `src/world/gen2/FieldMoves.lua:101` (badge table), `:482` (`SurfFunction` port) | implemented |
-| Fly field move + STORMBADGE + flypoint gating | `src/world/gen2/FieldMoves.lua:501-505` | implemented |
-| Trainer sight cones / `OBJECTTYPE_TRAINER` (sight 3 swimmers, sight 0 Tucker and Dawn) | `src/world/gen2/Trainers.lua:98` `Trainers.sees` | implemented |
-| `SPRITEMOVEDATA_SPINRANDOM_FAST` swimmers | `src/world/gen2/Npc.lua:23`, `:37`, `:68` | implemented |
-| `loadtrainer` / `startbattle` / `winlosstext` / `reloadmapafterbattle` / `endifjustbattled` | `src/script/gen2/Vm.lua`, `src/script/gen2/Opcodes.lua` | implemented |
-| Prize money, including the 4x split and Bank of Mom | `src/battle/gen2/Prize.lua:82` `Prize.reward`, `:181` (four quarters) | implemented |
-| Gym-leader battle/victory music via `GymLeaders` / `KantoGymLeaders` | `src/battle/gen2/BattleMusic.lua:15-33` | implemented |
-| Kanto badge page on the trainer card (EARTHBADGE displayed) | `src/ui/gen2/TrainerCard.lua:90`, `:161` | implemented |
-| `verbosegiveitem` (TM42 in Viridian City) | `src/script/gen2/Vm.lua` (`verbosegiveitem`) | implemented |
-| A driver that actually plays this stretch (Routes 19/20 surf trainers, Blue) | none - `tests/drivers/` has `gold_trainer_smoke.lua`, `gold_water_moves.lua`, `gold_map_callbacks.lua`, but nothing that reaches Kanto Route 19/20 or Viridian Gym | missing |
-| Section-specific regression coverage for `EVENT_CINNABAR_ROCKS_CLEARED` sequencing | not found by grep in `tests/` | missing |
-
-Every "implemented" row above is a generic engine capability, not a hand-port of these maps. Nothing in `src/` names `ROUTE_19`, `ROUTE_20` or `VIRIDIAN_GYM` (the only grep hits are `src/save_convert/data/event_flags_yellow.lua`, which is Gen 1 save conversion data and unrelated). So this section should work if the extractor and VM work, but it has never been exercised end to end.
-
-## 6. Unresolved / verify by hand
-
-1. **The walkthrough's boulder claim contradicts the asm.** "You can't go further north because you'll be blocked by those boulders south of Fuchsia City" is only true while `EVENT_CINNABAR_ROCKS_CLEARED` is clear. `maps/Route20.asm:12` `Route20ClearRocksCallback` sets that event on `MAPCALLBACK_NEWMAP` with no condition at all, and the walkthrough routes the player through Route 20 to reach Route 19. By the time the player is standing on Route 19 the six `changeblock` rocks are never placed, so northern Route 19 and the Fuchsia gate at `(7, 3)` are open. Treat the FAQ line as stale prose, not a gate. (What is genuinely true is that the FAQ's suggested Fly is faster than swimming back.)
-2. **Route 19's north connection vs. the gate warp.** `data/maps/attributes.asm:288` declares `connection north, FuchsiaCity, FUCHSIA_CITY, 0`, and there is *also* a warp to `ROUTE_19_FUCHSIA_GATE`. I did not decode `maps/Route19.blk` to determine whether the top block row is actually walkable, so I cannot say whether the north connection is reachable or purely decorative. Verify by hand before a bot relies on either route out.
-3. **Two trainers the walkthrough omits.** `TrainerSwimmermCameron` on Route 20 at `(12, 13)` (L34 MARILL) and `TrainerSwimmermHarold` on Route 19 at `(13, 28)` (L32 REMORAID, L30 SEADRA) both exist with sight range 3. The FAQ says "that's all the trainers" for Route 19, which is wrong. A bot surfing the full map will get pulled into both.
-4. **Blue's move set does not match the FAQ's strategy text.** The FAQ names Air Slash (Pidgeot) and Psychic + Hypnosis (Exeggutor); `data/trainers/parties.asm:3154` gives Pidgeot `QUICK_ATTACK, WHIRLWIND, WING_ATTACK, MIRROR_MOVE` and Exeggutor `SUNNY_DAY, LEECH_SEED, EGG_BOMB, SOLARBEAM`. Air Slash does not exist in Gen 2. Do not build AI expectations from the FAQ prose here.
-5. **The FAQ's "Blue is one of only two trainers tougher than Champion Lance"** is a subjective claim with no asm counterpart; nothing in `data/trainers/` ranks trainers.
-6. **`EVENT_VIRIDIAN_GYM_BLUE` is set in a prior section.** The walkthrough never mentions meeting Blue on Cinnabar Island, but `maps/CinnabarIsland.asm:23` is the only `clearevent` for that flag anywhere in the tree. If an earlier section's document does not cover `CinnabarIslandBlue`, this is an orphaned precondition and a bot will find an empty Viridian Gym with no in-game hint beyond `ViridianCityGrampsNearGym`.
-7. **Blue's map header sets the phone column to `TRUE`** (`data/maps/maps.asm:458`, the `ViridianGym` row). I found no `phone_call` or rematch entry naming `BLUE`, so I believe this is inert, but I did not exhaustively read `data/phone/`.
