+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:

-### 4. `mod.card`
+A translation may also set `"language": true` in the manifest. That is the
+one claim online play acts on: an install running nothing but verified
+translations may take an ONLINE MATCH or a TOURNAMENT instead of being
+asked to restart vanilla. The claim is checked, not taken -- the mod
+qualifies only if every record it writes lands in `text`, `strings` or
+`font`, it wraps no hook, subscribes to no event and requests no
+permission. Anything else and it is an ordinary content mod that happens to
+ship text.
+
+### 4. `games` (and the legacy `gen2compat`)
+
+Pokemon Gold is Gen 2, and it runs its own battle engine, overworld, script
+VM and save format. The mod API is shared across both generations (same hook
+names, same event names, same registry names) but Gold cannot serve all of it
+yet, so Gen 2 is opt-in. Say which games the mod is for:
+
+```json
+"games": ["gen1", "gen2"]
+```
+
+Each entry is a version id (`"red"`, `"blue"`, `"yellow"`, `"gold"`), a
+generation (`"gen1"`, `"gen2"`) or `"all"`;
+`src/mods/ModTargets.lua` resolves them off `GameVersion.ORDER` so nothing
+restates the game list. `python3 tools/modkit.py scaffold my_mod --games
+gen1,gen2` writes the key for you. The mod still installs to one directory,
+`mods/<id>/`, shared by every game -- targeting is declared, never filed.
+
+Absent means Gen 1 only, which is what every mod written before the key existed
+was tested as. `"gen2compat": true` is the legacy spelling, still accepted and
+purely additive (it *adds* the Gen 2 games), so no manifest can lose a game it
+already ran on. On a Gold boot a mod claiming no Gen 2 game is not loaded at
+all: the manager lists it as `ENABLED (NOT THIS GAME)` and says why, because a
+mod that half-applies reads as a broken mod. Claim Gen 2 once you have actually
+run your mod on Gold.
+
+Every token is enforced, per game: the loader gates on the same
+`ModTargets.supports` answer both mod surfaces draw, so `"games": ["blue"]`
+really does not load on Red and the skip line is the launcher's line, `For
+Blue, not Red`, and `"games": ["gold"]` alone does not load on Red either. A
+manifest with neither key still covers every Gen 1 game, so nothing written
+before the key existed changes behavior; list both generations or say `"all"`
+when you mean everywhere.
+
+`docs/mod-api-gen2-compat.md` is the compatibility matrix: what works on Gold
+today (40 of the 46 registries, 40 event and 43 hook names shared with Gen 1,
+and 24 Gen 2-only ones), which registries have no Gen 2 home and drop their
+writes with a report, and which hooks and events are still to come.
+`docs/preparing-your-mod-for-gen2.md` is the step-by-step migration guide for a
+Gen 1 mod, and it is the one to start from.
+
+Two consequences worth knowing before you claim Gen 2.
+
+**Dependencies are contagious.** A mod whose hard dependency does not run here
+is left out too, with the dependency's own wording (`depends on X, which does
+not run here (For Blue, not Red)`). It is reported as a skip, not as a failure,
+and neither mod lands on the boot error list, but the mod does not run, so
+every hard dependency has to cover the same games.
+
+**The player can override you.** The claim is yours, and a mod written before
+the key existed can never carry one, so the manager's detail pane offers
+`TRY HERE ANYWAY` for any mod that does not claim the game being played. It
+persists per game in `options.modsGen2[id][version]` and takes effect on the
+next boot; forcing a mod onto Red does not force it onto Gold. A forced mod
+loads normally and keeps a note saying its author never verified it here.
+
+**Prefer the API on Gold, but the Gen 1 names still work.** Gen 2 is a
+parallel module tree behind `src/core/Game2.lua`. In new code take the live
+game from `mod.game` (or the `game.ready` payload, or any `ui.*` hook's first
+argument) and the world from `mod.world`; both resolve per generation, and
+neither needs `engine_internals`.
+
+For the mods written before Gold existed, a require made from a mod's own file
+is answered on a Gold boot by an adapter presenting the Gen 1 API over Gen 2
+internals. Fifteen names are served -- `src.core.Game`,
+`src.world.OverworldController`, `src.world.Map`, `src.world.NPC`,
+`src.world.Collision`, `src.world.WorldAPI`, `src.world.PikachuFollower`,
+`src.world.FieldDefaults`, `src.pokemon.Boxes`, `src.script.ScriptRunner`,
+`src.ui.PartyMenu`, `src.ui.StartMenu`, `src.ui.OptionsMenu`, `src.ui.BoxMenu`
+and `src.battle.BattleState`. `src/mods/Gen2Compat.lua` is the full table and
+publishes what it covers through `Gen2Compat.coverage(name)`, whose members are
+`backed`, `warned` or `absent`. A name with no adapter (`src.script.Commands`,
+`src.ui.OptionRows`) is reported against the mod that required it, and a member
+an adapter cannot back is absent or logs once rather than answering wrongly.
+
+Things no adapter can fix, all mod-side: a hardcoded version allow-list
+(`GameVersion.get() == "red" or ...`) excludes you from Gold by construction;
+Gold's builtin screen ids carry a `Gen2` prefix, so a string match on
+`"BoxMenu"` matches nothing there; a write to a field on a live Gen 2 menu
+instance is inert; and `map.warpAt` is a table on Gen 1 and a method on Gold,
+so indexing it raises. Each has a route that works on both generations, in
+`docs/preparing-your-mod-for-gen2.md`.
+
+Check it statically, then load it headless:
+
+```sh
+python3 tools/modkit.py gen2check mods/my_mod
+```
+
+```lua
+local run = T.sdk.loadMod("mods/my_mod", { generation = 2 })
+T.eq(run.mod and run.mod.state, "loaded",
+  "runs on gen 2: " .. tostring(run.mod and run.mod.skipReason))
+T.eq(#run.errors, 0, "and loads with no boot errors")
+```
+
+Assert the state, not only the error count: a gate skip is deliberately not an
+error, so `#run.errors == 0` passes for a mod that never ran a line.
+
+`gen2check` answers `will load`, `will load but degrade` or `will not work`,
+with a `MK4xx` finding per site and an `unresolved:` note, with a file and a
+line, for every reach a static scan could not follow. Neither substitutes for a
+real Gold boot.
+
+### 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`

-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.

+
+### External setup
+
+1. Put your legally obtained Red, Blue, or Yellow ROMs on an external drive.
+   Mod ZIPs can go on the same drive.
+2. Connect the drive to the Xbox and open Gen1Recomp.
+3. Select **Import ROM** or **Import Mod**, then choose the file with the Xbox
+   file picker.
+4. Repeat the ROM import for each version you want to use.
+
+### Internal setup
+
+1. Create a folder named `baseroms` on your PC and place your legally obtained
+   Red, Blue, or Yellow ROMs inside it.
+2. ZIP the folder, keeping `baseroms` at the top level of the archive.
+3. Launch Gen1Recomp once, then close it.
+4. Open Xbox Device Portal and upload the ZIP to
+   `Gen1Recomp/LocalState/pokemon-love2d/`.
+5. Choose **Yes** when Device Portal asks whether to extract the archive.
+6. Open Gen1Recomp. The launcher checks baseroms once at startup. When it finds a compatible ROM, that game’s tab shows ROM FOUND and an Import detected ROM button.
+
+ROMs, generated game data, saves, and mods remain in LocalState and are not
+included in the app.
+
+Source builds and package details are covered in
+[the Xbox UWP build notes](ports/uwp/BUILD.md).

+#
+# The launcher uses SHDIR-relative paths and bundles the LÖVE 11.5 aarch64

+# Install on device:
+#   1. Install PortMaster for the handheld firmware.

+## 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) is
-  unreachable since the TM is granted with the victory. 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

-
-## 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.
-
-## Validation against the original
-
-- `tests/run_tests.lua` pins hand-checked values: L5 Bulbasaur 19 HP /
-  9 Atk at 0 DVs, L100 Mewtwo 415 HP / 406 Spc at max DVs+statExp,
-  MEDIUM_SLOW(5) = 135, type chart spot checks, deterministic damage
-  rolls, Route 1 slot 1 = L3 Pidgey.
-- The autopilot run reproduces the original's early flow on real map
-  data: Pallet sign text, lab door warp target (5,11), Oak's Lab exit by
-  walking off the mat, connection into Route 1 at matching x.

-# 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.

-## Reimplemented unused Prof. Oak and Rocket Chief battles
-
-The original ROM defines trainer data for `PROF_OAK` and `CHIEF`
-(`data/trainers/parties.asm`) but never attaches either to an NPC, so
-both battles are unreachable in the real game. This project makes them
-fightable after the Hall of Fame:
-
-- Prof. Oak battles you in Pallet Town once `EVENT_BEAT_CHAMPION_RIVAL`
-  is set, using `ProfOakData`'s three starter-matched teams (the team is
-  picked by the type that counters your starter, mirroring the rival).
-- The Celadon Game Corner Chief battles you in his house post-game.
-  `ChiefData` is empty in the ROM, so `OPP_CHIEF` is given a
-  reconstructed party.
-
-This is an intentional divergence: neither battle can be triggered in the
-original game.
-
-## Reimplemented unused Silph Co. card-key doors
-
-`engine/events/card_key.asm` and the unused `CardKeyTable1/2/3` coordinate
-lists (`data/events/card_key_coords.asm`) describe locked doors for Silph
-Co. floors 2F-11F, but no retail `.blk` map layout ever places the closed
-door block at those coordinates, so the card key check is dead code in
-the original game. This project stamps the closed door block (`$54`/`$5f`
-on floors 2F-10F, `$20` on 11F) over each of the 20 door coordinates on
-map load, and swaps it for the open block once that door's
-`EVENT_SILPH_CO_n_UNLOCKED_DOORn` flag is set (using the key from a Team
-Rocket grunt, as in the original's unused design).
-
-This is an intentional divergence: the doors are not visible or
-functional in the original game. The door layout lives in
-`tools/rom_manifest.json` (`field.cardKeyDoors.closedDoors`), hand-ported
-since no retail ROM data encodes it; `src/import/RomExtractor.lua` copies
-it straight through on ROM import.

docs/launcher.md

-# Launcher
-
-The launcher is `src/import/RomImporter.lua`, the first-run / title screen
-that runs before `Game:load`. Besides ROM import (see the file's own header)
-it hosts a tabbed shell covering per-game save slots and a mod manager. This
-file documents the runtime model; the visual spec lives separately.
-
-## Android multi-ROM / mod / save import
-
-On Android, `love.system.pickFile([kind])` opens the Storage Access Framework
-picker (`GameActivity.showFilePicker`); the chosen file is copied into the app
-save directory as:
-
-| `kind` | Destination |
-| --- | --- |
-| nil / `"rom"` | `picked_rom.gb` (open) |
-| `"mod"` | `picked_mod.zip` (open) |
-| `"sav"` / `"save"` | `picked_save.sav` (open) |
-
-Export uses a separate API: `love.system.createFile(suggestedName)` →
-`GameActivity.showCreateDocument` (`ACTION_CREATE_DOCUMENT`), which copies
-staged `pending_export.sav` to the user-chosen URI and writes `export_done.flag`
-for the launcher to acknowledge on refocus.
-
-`RomImporter` then imports on refocus / Choose:
-
-- **ROMs** via `findPendingRom`: only a 1 MiB `.gb` whose SHA-1 maps to a
-  version that is **not** yet ready counts as pending. A leftover
-  `picked_rom.gb` from Red therefore cannot block Blue's Choose (issue #167).
-- **Mods** via `findPendingMod`: Prefer `picked_mod.zip`, or (on Choose) any
-  other `.zip` at the save-dir root (USB copy).
-- **Saves** via `findPendingSav`: Prefer `picked_save.sav`, or (on Choose) any
-  other `.sav` at the save-dir root.
-
-After a successful import the consumed save-dir file is removed.
-
-**Manual check (device/emulator):** import Red → switch to Blue → Choose →
-system file picker must appear (not a silent Red re-extract) → pick Blue →
-Blue becomes ready beside Red. On the MODS tab, Import mod .zip must open the
-same system picker and install the chosen archive on return.
-
-## Tab structure
-
-`self.tab` is one of `"red"`, `"blue"`, `"yellow"`, `"mods"`. The tab bar
-draws one chip per game plus a MODS chip and rebuilds `self.tabRects` every
-frame so `mousepressed` can dispatch clicks; switching tabs mid-import is
-allowed (a dropped ROM still routes by SHA-1 regardless of which tab shows).
-
-- A game tab (`_drawGamePanel`) shows the ROM card, the SAVE FILES card, the
-  Play button, and the SAVE SLOT card in a responsive two-column grid (see
-  Responsiveness). The MODS tab (`_drawModsPanel`) shows the mod list instead.
-- The self-updater banner (`self.Check`, see `docs/updater.md`) draws as a
-  centered pill in a reserved band just above the footer, on every tab. That
-  position is unchanged by this redesign, so `docs/updater.md` needed no edits.
-
-## Save slot model
-
-All slot I/O lives in `src/core/SaveData.lua` and goes through the same fs
-abstraction (`persistFs`) every other save/options call uses, so portable
-mode (an `io.*` filesystem used when `portable.txt` marks the install)
-keeps working unchanged.
-
-- **Files.** A version's playthroughs live under `saves/<version>/`, one file
-  per slot: `saves/<version>/slot1.lua` plus a rolling `.bak` and staged
-  `.tmp` witness (`slotNames`), mirroring the write/recovery discipline
-  `SaveData.save`/`load` already use for the flat legacy file. Slot ids match
-  `slot%d+`; `createSlot` allocates one past the highest existing number so a
-  reused id can never collide with a lingering file.
-- **Registry.** The ordered slot list and which one is active persist in
-  `options.lua` (via the existing `SaveData.loadOptions`/`saveOptions`):
-  `options.saveSlots = { [version] = { list = {"slot1", ...}, active = "slot1" } }`.
-  Custom slot labels (#205) live alongside them in the same registry:
-  `options.saveSlots[version].names = { slot1 = "Nuzlocke" }`, written by
-  `SaveData.renameSlot` (trimmed; an empty label clears it) and surfaced on
-  each `listSlots` row as `label` (the launcher row shows `label`, falling
-  back to the player name). `deleteSlot` drops the label with the slot.
-  Renaming never touches the save file, so an empty slot can be labeled.
-  On desktop, right-clicking a slot row opens the inline rename modal
-  (Enter commits, Esc cancels); touch has no secondary button, so the
-  affordance is desktop-only.
-- **Active slot resolution.** `saveNames(version)`, the function every
-  existing caller (`TitleState` hasSave/load/save, recovery order) already
-  goes through, now resolves the *active* slot instead of a fixed flat name.
-  Resolved once per version per process (`ensureVersionSlots`, cached in
-  `activeSlotCache`/`slotsChecked`): a registry entry wins; otherwise a lazy
-  legacy migration may create one; otherwise the flat legacy path is used
-  (`save.lua` / `save_blue.lua`), so a pre-slots install keeps working as before.
-- **Legacy migration.** One-time per version, lazy on first
-  `listSlots`/`load`/`saveNames` call (`tryMigrateLegacy`): if a flat legacy
-  file exists and no `saves/<version>/` registry does, its main + `.bak` are
-  copied into `saves/<version>/slot1.lua(.bak)`, verified readable
-  (`decodeSlot`: main, then `.tmp`, then `.bak`), and only then are the
-  originals removed and `slot1` registered as active. A copy that fails to
-  verify leaves the originals in place; migration never loses data.
-
-The launcher-facing API:
-- `SaveData.listSlots(version)` -> array of `{id, exists, name, meta}` for
-  every registered slot. `name` is the save's player name, or `nil` for an
-  empty slot; `meta` is `{badges, timeText, dexCount}` (the same fields the
-  title screen's `ContinueInfo` shows) or `nil`. The pure part,
-  `SaveData.slotSummary(save)`, is unit-testable with no filesystem.
-- `SaveData.setActiveSlot(version, slotId)` registers the id if new, persists
-  it as active, and updates the process cache so the very next save/load
-  lands there. The launcher calls this the moment a slot row is clicked
-  (`RomImporter:_selectSlot`); pressing Play needs no signature change, since
-  `Game.lua`/`main.lua` still just call `SaveData.load()`/`save()`.
-- `SaveData.createSlot(version)` -> new slot id, registered but with **no
-  save file written**. An empty slot means the title screen offers NEW GAME
-  only, which needs no further changes.
-- `SaveData.deleteSlot(version, slotId)` removes the slot's
-  main/`.bak`/`.tmp` files, drops it from the registry, and if it was active
-  points active at another remaining slot (or clears active when the list is
-  empty). The launcher's SAVE SLOT panel Delete control calls this.
-
-## Launcher mod manager
-
-`src/mods/LauncherMods.lua` is a launcher-only read of the mod set. It runs
-before `Game:load`, so **it never loads a mod's entry chunk**; only
-`manifest.json` is read and validated (`src/mods/Manifest.validate`), the way
-`Loader:_discover` finds mods without running them. The real loader
-(`src/mods/Loader.lua`) still owns the actual load at boot.
-
-- `LauncherMods.list()` scans `mods/` one level deep (first id wins on a
-  duplicate) and returns one row per mod:
-  `{id, name, version, badge, description, enabled, status, statusDetail}`.
-  `badge` is the manifest's `category`, falling back to `profile`, then
-  `"MOD"`, uppercased. `enabled` reads `options.mods[id]` (missing means
-  enabled, matching the loader's own default).
-- `status` is `"ok"`, `"warn"`, or `"conflict"`, computed by the pure
-  `LauncherMods.deriveList`/`statusFor` against `ManagerState.resolveToggle`
-  and the validated manifests: `conflict` when enabling this mod collides
-  with another enabled one; `warn` for an out-of-range `game_version` or an
-  absent/disabled/wrong-version hard dependency; `ok` otherwise. Having no
-  `love.*` calls, this half is table-driven by the test suite on its own.
-- `LauncherMods.setEnabled(id, bool)` persists `options.mods[id]` as a plain
-  boolean, the exact shape `Loader:_saveState` writes, so the running game
-  and the in-game `ManagerState` see the change on next boot. The mods panel
-  calls this on every toggle and re-derives the list right away
-  (`RomImporter:_refreshMods`) so a status change (e.g. a new conflict)
-  shows without waiting for a reload.
-- `LauncherMods.installZip(path)` mounts the archive with
-  `love.filesystem.mount`, locates the mod root via `locateRoot` (manifest at
-  the zip root, or inside one top-level folder), validates its manifest, and
-  copies the tree into the save-dir `mods/<id>/` before unmounting. Rejects a
-  duplicate of an already-installed mod id, and accepts either an external
-  path string or a LOVE `DroppedFile`, staging a dropped file into a save-dir
-  temp first (mount only reaches save-dir-relative paths), the same way
-  `RomImporter` handles a dropped ROM. A failed copy rolls its partial tree
-  back, and every path unmounts and clears the staged temp file.
-- `LauncherMods.uninstall(id)` removes `mods/<id>/` and clears
-  `options.mods[id]` so a later reinstall starts from the loader's default
-  (enabled). The mods panel Delete control calls this and re-derives the list.
-
-## Import / Export save
-
-The SAVE FILES card wires a raw Gen1 `.sav` battery image to the save slots
-through `src/import/SaveFileIO.lua`, which sits on top of
-`src/save_convert/SaveConvert.lua` and the slot API in `SaveData`.
-
-- **Import save** is live once the game's ROM is imported (playable). It opens
-  a native `.sav` picker (`chooseSav` on desktop; on Android,
-  `love.system.pickFile("sav")` → `picked_save.sav`, same SAF path as ROMs).
-  `SaveFileIO.importToSlot` reads the bytes (an absolute path, a save-dir
-  relative name, a dropped LOVE file, or raw bytes),
-  guards the 32768-byte size, runs `SaveConvert.importSav` (which also rejects
-  a bad main-data checksum), then registers a fresh slot (`SaveData.createSlot`),
-  writes it (`SaveData.writeSlot`), and makes it active (`SaveData.setActiveSlot`).
-  The meta stamp is re-stamped off `gen1_import` to the current numeric format
-  so `SaveData.load`'s migration pass accepts the slot. On success the SAVE SLOT
-  panel is refreshed with the new slot selected.
-- **Export save** is live only when the active slot actually holds a save
-  (checked against `listSlots`). `SaveFileIO.exportActiveSlot` loads the active
-  slot, encodes it back with `SaveConvert.exportSav` (a slot never keeps
-  `rawImport`, so this is a zero-filled template export, which is valid), and
-  writes `exports/gen1recomp-<version>-<slotId>.sav` in the save directory
-  (`love.filesystem.createDirectory("exports")`). On desktop it returns the
-  absolute path (`love.filesystem.getSaveDirectory()`), which the notice line
-  shows with an "Open folder" affordance (`love.system.openURL("file://" .. dir)`).
-  On Android the bytes are also staged as `pending_export.sav` and
-  `love.system.createFile(suggestedName)` opens `ACTION_CREATE_DOCUMENT` so the
-  player can save to Downloads / Drive / etc.; on return `export_done.flag`
-  makes focus show "Save exported."
-- **Drag-drop.** `filedropped` routes a `.sav` to the import path for the
-  currently active game tab; when a non-game tab (mods, or the locked yellow
-  placeholder) is showing it defaults to red, the always-present first game
-  (`_savedropTarget`). `.gb` (ROM) and `.zip` (mod) routing is unchanged.
-- **Failure UX.** Every error path (wrong size, bad checksum, write failure,
-  nothing to export, ROM not imported yet) surfaces as a red notice line on the
-  card. Nothing raises and nothing silently no-ops.
-
-`SaveFileIO` is love-free enough to unit-test through the same in-memory
-filesystem stub the slot backend uses (`tests/engine/save_file_io_tests.lua`).
-
-## Responsiveness
-
-Every measurement derives from `love.graphics.getDimensions()` each frame
-plus the existing global scale `s = clamp(height / 768, 0.7, 1.6)`; nothing
-assumes a fixed window size. The game panel's two-column grid (ROM/SAVE
-FILES/Play on the left, SAVE SLOT on the right) collapses to one stacked
-column, slot card below Play, when the window is too narrow for both
-`~300 * s`-wide columns. The save-slot list and the mod list both scroll
-(wheel, or drag on touch/desktop) clamped to their own content extent,
-recomputed every draw. The tab bar labels only the active chip so it stays
-narrow-safe, and content caps out at `~1440 * s` wide, centered.
-
-The desktop window has a floor of 480x360 (`conf.lua` `minwidth`/`minheight`),
-under which the cards stop being readable at all. Mobile ignores it: those
-windows are fullscreen.
-
-### Page scroll
-
-Two columns fit any window the launcher is likely to open in; one stacked
-column does not. On a phone-shaped window the ROM card, SAVE FILES, Play and
-SAVE SLOT together run past the bottom, and a footer pinned to the window
-bottom painted over them with the overflow unreachable.
-
-So the whole column under the tab bar -- panel, updater banner, footer --
-scrolls as one page whenever it is taller than the room below the tab bar:
-
-- The strip, logo and tab bar stay pinned, so navigation is always on screen.
-  Everything else draws at `contentTop - pageScroll` inside a scissor, and the
-  footer is laid out downward from `footerTop` right after the content instead
-  of upward from the window bottom.
-- `RomImporter.pageScrollFor(naturalH, viewportH, scroll)` is the whole
-  decision, pure and pinned by `tests/engine/launcher_page_scroll.lua`. A
-  window that grows back drags the offset down with it, so the page can never
-  stay parked past its own end.
-- The panels report their natural height as they draw (`_drawGamePanel` and
-  `_drawModsPanel` return it), so the decision reads the previous frame's
-  measurement -- the same one-frame settle the two lists already rely on.
-- **One scroll axis at a time.** While the page scrolls, the panels draw
-  `paged`: the slot and mod lists take their natural height, keep no inner
-  scroll region and report a max of 0, so the wheel, the right stick and a drag
-  all move the page and never fight a list for the same gesture. Two-column
-  layouts do not overflow, `paged` stays false, and every one of these behaves
-  exactly as it did before.
-- Hit testing follows the clip: `inside` (clicks) and `_ptIn` (hover) reject a
-  rect that scrolled out of the viewport, so a control that slid under the tab
-  bar cannot be clicked through it. Tab chips carry `pinned = true` and are
-  exempt. `pageScroll` resets on a tab change, each tab being a different
-  length.
-- A press on empty background pans the page, resolved in `_updateSlotDrag` like
-  every other drag here.
-
-### Dragging on Android
-
-The launcher is handed no move events on any platform: `main.lua` forwards
-neither `touchmoved` nor `mousemoved` while it is up, which is why every drag
-here is resolved by polling inside `draw` instead. Desktop polls the mouse;
-Android used to poll nothing at all ("no reliable pointer polling" meant its
-mouse emulation), so it had no scroll gesture whatsoever -- fine while every
-scroll region was an inner list with a wheel alternative, useless the moment
-the page itself became the thing that scrolls, since a phone is exactly where
-it overflows.
-
-`love.touch` is pollable, so `_pointerHold` reads the first active touch there
-and hands `_updateSlotDrag` the same (held, y) pair the mouse gives on desktop.
-Consequences:
-
-- Slot rows and mod toggles ARM on press and commit on release on Android too,
-  matching desktop, so a swipe that starts on a card scrolls instead of
-  selecting the row it started on.
-- `touchPollable` (set once in `new`) gates all of it. Where `love.touch` is
-  missing, every Android path is exactly what it was: act on press, never arm,
-  no drag.

+# Linux ARM SBC Handhelds (PortMaster)
+
+Download `gen1recomp-*-sbc-portmaster.zip` from the [Gen1Recomp releases](https://github.com/bryanthaboi/gen1recomp/releases). This build targets 64-bit Linux ARM handhelds with PortMaster, including compatible H700 devices.
+
+## Install
+
+1. Unzip the release. It contains `gen1recomp-sbc.sh` and a `gen1recomp-sbc/` folder.
+2. Copy both as siblings into your device's PortMaster ports directory, commonly `Roms/Ports (PORTS)/` or `Roms/PORTS/`.
+3. Install PortMaster for your firmware and refresh the Ports list.
+4. Copy your legally owned canonical US Red or Blue `.gb` file into `gen1recomp-sbc/lovegame/`.
+5. Launch **gen1recomp-sbc** from Ports and choose the ROM.
+
+The pack includes `portable.txt`, so saves and ROM-derived cache remain beside the game on the SD card. The build never ships ROM-derived bytes.
+
+Canonical US cart SHA-1 values:
+
+- Red: `ea9bcae617fdf159b045185467ae58b2e4a48b9a`
+- Blue: `d7037c83e1ae5b39bde3c30787637ba1d4c48ce2`
+
+## Controls
+
+| Input | Action |
+| --- | --- |
+| D-pad | Move cursor |
+| A | Click / confirm |
+| L1 / R1 | Switch tabs |
+| Start / Select | Play or choose ROM |
+
+In-game controls use the normal PortMaster/SDL mapping and can be rebound in **OPTIONS → CONTROLS**.
+
+## Runtime and suspend
+
+The package bundles PortMaster's LÖVE 11.5 aarch64 runtime. The launcher sources `control.txt`, calls `get_controls`, applies an optional CFW override, invokes `pm_platform_helper`, and calls `pm_finish` on exit. Paths are relative to the launcher, allowing different firmware mount points.
+
+Suspend/resume uses the existing LÖVE focus/visibility lifecycle: input is reset on focus loss and the game resumes when the window becomes visible again. Exact power-button behavior remains firmware-dependent; hardware validation has been performed on the TrimUI Brick, not every SBC or H700 device.
+
+## Building
+
+Release workflows build this automatically. Standalone builds resolve the latest published Gen1Recomp release by default:
+
+```sh
+./build-linux-arm-sbc.sh --version 0.1.75
+```
+
+For development, package a local checkout explicitly:
+
+```sh
+GEN1RECOMP_SOURCE_DIR="$PWD" ./build-linux-arm-sbc.sh --version 0.1.0
+# or: ./build-linux-arm-sbc.sh --source "$PWD" --version 0.1.0
+```
+
+The generated `port.json` records the source release tag. `install-linux-arm-sbc.sh` is a macOS helper for copying a built pack to a mounted SD card.
+
+PortMaster device support and runtime integration are maintained in the [PortMaster](https://github.com/PortsMaster/PortMaster-New) ecosystem.

+# Linux arm64 (aarch64) AppImage
+
+Releases ship `gen1recomp-<version>-linux-arm64.AppImage` alongside the
+existing x86_64 `gen1recomp-<version>-linux.zip`. It targets 64-bit ARM
+desktop Linux: Raspberry Pi 4/5 running Raspberry Pi OS, Armbian and other
+SBC distros, arm64 VMs on Apple Silicon, Ampere/Graviton desktops, and the
+aarch64 handhelds that run a full distro.
+
+> The Anbernic RG34XXSP has its own PortMaster-style pack
+> (`gen1recomp-*-rg34xxsp-stockos64-mod.zip`, see
+> [anbernic-rg34xxsp.md](anbernic-rg34xxsp.md)). That one bundles PortMaster's
+> LÖVE runtime and expects the device's own SDL; this AppImage is the generic
+> desktop-Linux artifact and shares nothing with it but the `game.love`.
+
+## For players
+
+```sh
+chmod +x gen1recomp-*-linux-arm64.AppImage
+./gen1recomp-*-linux-arm64.AppImage
+```
+
+Then use **Import ROM** in the launcher to point it at your own legal Red /
+Blue / Yellow cartridge dump, exactly as on every other platform.
+
+If your system has no FUSE (`dlopen(): error loading libfuse.so.2`), either
+install it (`sudo apt install libfuse2`) or run without it:
+
+```sh
+./gen1recomp-*-linux-arm64.AppImage --appimage-extract-and-run
+```
+
+### What the host has to provide
+
+Very little, and this is enforced by an assertion in the build rather than by
+good intentions. The only libraries the AppImage requires at startup are:
+
+```
+glibc 2.29+   libstdc++   libfreetype6   zlib
+```
+
+Everything else — OpenGL/Mesa, X11, Wayland, KMSDRM, ALSA, PulseAudio — is
+**dlopened**, so it is used when present and skipped when absent. That means
+one image runs on a full desktop, on a Wayland-only session, on a
+KMSDRM-only handheld with no X server, and on a box with ALSA but no
+PulseAudio, without a different build for each.
+
+That property does not come for free from Debian's packages, and getting it
+is most of what the build below is doing; see
+[Why five libraries are built from source](#why-five-libraries-are-built-from-source).
+
+## For builders
+
+```sh
+scripts/build_linux_arm64.sh --version 0.1.0
+```
+
+Output:
+
+```
+dist/linux-arm64/gen1recomp-<version>-linux-arm64.AppImage
+dist/linux-arm64/gen1recomp-<version>-linux-arm64.AppImage.sha256
+```
+
+Useful flags: `--game-love PATH` reuses an already-packed payload (CI does
+this so every platform ships identical bytes), `--rebuild-image` forces the
+builder container to rebuild, `--clean-cache` throws away the pinned
+downloads and the compiled LÖVE prefix.
+
+### Requirements
+
+An **aarch64 host** with **docker or podman**. A Raspberry Pi 5 is the
+reference machine (a cold build takes about 10 minutes on one — six libraries
+plus the engine; rebuilds reuse the cached prefix and take seconds). Apple Silicon with Docker
+Desktop and GitHub's `ubuntu-24.04-arm` runner both work too.
+
+The script refuses to run on x86_64 rather than falling back to qemu-user
+emulation: that path takes hours and has produced miscompiled LuaJIT.
+
+### Why this is not just another `scripts/build.sh` target
+
+`scripts/build.sh linux` downloads LÖVE's official `love-11.5-x86_64.AppImage`,
+unpacks its squashfs, drops `game.love` in, and glues it back together. That
+trick is not available here — **LÖVE publishes no aarch64 binary at all.** The
+11.5 release has win32, win64, macOS, Android, iOS and one x86_64 AppImage,
+and that is the entire list.
+
+So this build compiles LÖVE 11.5 from the official `linux-src` tarball and
+assembles the AppImage from scratch. Every pinned input — the LÖVE source, the
+five libraries built alongside it, and the AppImage type-2 runtime — is
+SHA-256 verified on the host before the container ever sees it, and the
+container itself runs with no network access.
+
+### Why the build happens in a Debian bullseye container
+
+glibc is backward compatible but not forward compatible: a binary linked
+against glibc 2.41 will not start on a system with 2.31, and there is no way
+to fix that after the fact. Compiling on the oldest base we support is
+therefore the only thing that makes one artifact work everywhere.
+
+Bullseye (glibc 2.31) is that base. The resulting binaries actually come out
+needing only **glibc 2.29** and **GLIBCXX_3.4.21**, so the AppImage covers
+everything from Ubuntu 20.04 and Raspberry Pi OS bullseye through current
+trixie.
+
+This is a statement about the *compile environment*, not about where the
+artifact runs — building on your own newer distro would silently raise that
+floor and strand every user on an older one, with no symptom until they
+download it. CI enforces the floor: `linux-arm64-build` fails if the highest
+required glibc symbol version climbs above 2.31.
+
+### Why five libraries are built from source
+
+SDL2, OpenAL, libtheora, libogg/libvorbis and libmpg123 are compiled rather
+than installed from bullseye. In every case the reason is *correctness*, not
+a newer version number — Debian builds these for a system where every
+dependency is installed and co-versioned, which is the opposite of an
+AppImage's situation. Each one broke the build in a different way, and all
+three failure modes are now assertions that fail the build instead of
+shipping.
+
+**1. Hard-linked backends (SDL2, OpenAL).** Debian's `libSDL2` lists
+`libpulse`, `libasound`, `libX11` and `libwayland-client` as `DT_NEEDED` —
+resolved by the loader at startup, not dlopened. An AppImage bundling it
+refuses to start unless the host has *all four*. It appeared to work in
+testing only because a desktop Pi has all four; a headless CI runner is what
+exposed it. Debian's OpenAL does the same via `libsndio`, which itself
+hard-links `libasound`. Built from source with `--enable-*-shared` and
+`ALSOFT_DLOPEN`, both dlopen their backends instead.
+
+**2. A stray link (libtheora).** Debian's `libtheoradec.so.1` is linked
+against `libcairo.so.2` — a packaging artifact, since a video decoder has no
+business drawing vector graphics — and cairo drags in X11, xcb, fontconfig
+and freetype. `--disable-examples` produces a `libtheoradec` needing only
+`libogg`.
+
+**3. SONAME collision with the host (ogg, vorbis, mpg123).** The subtle one.
+OpenAL dlopens ALSA, ALSA's config loads its PulseAudio hook plugin, and that
+plugin pulls the *host's* `libsndfile` into our process. `libsndfile` links
+`libogg`, `libvorbis` and `libmpg123` — the same three we bundle. The loader
+resolves a SONAME exactly once per process, so the host's `libsndfile` binds
+to *our* copies:
+
+```
+openal -> libasound -> libasound_module_conf_pulse -> libsndfile (host, new)
+                                                         `-> mpg123_info2 -> libmpg123 (ours, bullseye 1.26)
+```
+
+`mpg123_info2` arrived in mpg123 1.32, so the plugin failed to relocate, ALSA
+config collapsed, and the game ran with **no audio device at all**. Not
+bundling these instead would make `libogg`/`libvorbis`/`libmpg123` mandatory
+host packages; building them current means our copies *satisfy* the host's
+`libsndfile` rather than starving it.
+
+The same collision is why the font stack — freetype, fontconfig, libpng,
+brotli, zlib — is left to the host entirely. Bundling a bullseye freetype
+2.10.4 meant a host `libcairo` could not find `FT_Get_Transform` (added in
+2.11) and the game died at startup. Leaving the whole stack to the host keeps
+it self-consistent, while `liblove` — compiled against 2.10.4 — only ever
+asks for symbols every supported host already has.
+
+The general rule this all reduces to: **never bundle a library the host's own
+stack may also load, unless yours is at least as new as theirs.**
+
+### CI
+
+Three jobs, path-gated on `scripts/build_linux_arm64.sh`,
+`scripts/linux-arm64/`, `scripts/pack_love.sh` and this document:
+
+- **`linux-arm64-selftest`** (`ubuntu-latest`, x86_64) — offline gate. Checks
+  the pins are real digests on a dated tag rather than the moving
+  `continuous` one, that the Dockerfile still builds on bullseye, that the
+  exclude list still classifies known sonames correctly, that AppRun still
+  launches `game.love` with `--fused`, and that the host-arch guard actually
+  fires. Needs no container and no arm64 machine.
+- **`linux-arm64-build`** (`ubuntu-24.04-arm`) — the real build, then extracts
+  the artifact and asserts the layout, that every bundled object resolves
+  under AppRun's `LD_LIBRARY_PATH`, and that the glibc floor is still ≤ 2.31.
+  Uploads the AppImage for 7 days.
+- **release** — `linux-arm64` runs on `ubuntu-24.04-arm`, reuses the shared
+  `game.love` from the `love-payload` job, and the AppImage is staged and
+  published like every other release asset.
+
+Unlike the Switch job, none of this needs secrets or self-hosted hardware, so
+it runs on fork PRs too.
+
+### Updating the pins
+
+Both pins live in `scripts/linux-arm64/common.sh`:
+
+- `LOVE_VERSION` / `LOVE_SRC_SHA256` — bumping any version invalidates the
+  cached prefix automatically (its name is keyed by every source version at
+  once, so a partial rebuild cannot mix vintages). Check that bullseye still
+  has `-dev` packages new enough for the new release; `build_appimage.sh`
+  asserts every optional module actually linked, because LÖVE's `configure`
+  exits 0 and silently drops a module when one is missing.
+- `SDL2_*`, `OPENAL_*`, `THEORA_*`, `OGG_*`, `VORBIS_*`, `MPG123_*` — the
+  source-built libraries. Bumping these is usually safe and occasionally
+  necessary: `libmpg123` in particular must stay at least as new as what a
+  target host's `libsndfile` expects, which is asserted for `mpg123_info2`.
+- `APPIMAGE_RUNTIME_TAG` / `APPIMAGE_RUNTIME_SHA256` — always a dated tag
+  from [AppImage/type2-runtime](https://github.com/AppImage/type2-runtime/releases).
+  The selftest fails the build if this ever points at `continuous`.

+# Mods and Gen 2 (Gold)
+
+The mod API is one API across both generations. Hook names, event names,
+registry names and the `mod.*` facade are shared on purpose: a mod that runs on
+Red should be able to run on Gold without learning a second vocabulary.
+
+What differs is how much of it Gold can actually serve, and that is why Gen 2
+support is something a mod **declares** rather than something it inherits.
+
+## What you can rely on today
+
+The short version, for an author deciding what to write:
+
+- **Every registry name, hook name and event name means the same thing in both
+  games.** Nothing is prefixed, renamed or repurposed per generation. Where Gen
+  2 genuinely carries more, the record or the payload gains a *field*.
+- **40 of the 46 registries are available on Gold.** 17 keep their Gen 1 target
+  outright (`commands`, `tokens`, `growth_rates`, `battle_sprite_scales` and
+  `render_pipelines` among them), 16 route to a Gen 2 table under the same
+  name, 6 are Gen 2-only systems Red has no counterpart for, and `migrations`
+  is a code registry with no data target in either game. The other 6 are gated,
+  and are listed below with the consumer change each one still needs.
+- **A registry with no home in a generation is reported, never silently
+  merged.** The write is taken, dropped, and named once per mod in the same
+  error feed the mod manager shows -- in both directions, so a Red boot writing
+  to `decorations` is told exactly as a Gold boot writing to `map_scripts` is.
+- **40 event names and 43 hook names have a call site in both generations**, so
+  one subscription serves both games. `tests/engine/gate_gen2_mod_api.lua`
+  reads those names back out of the source and fails if a site is renamed or
+  deleted on either side, and fails again if a new shared site appears without
+  being listed here.
+- **24 further names are Gen 2-only** (friendship, breeding, the Pokegear, the
+  radio, Pokerus, the roamers, Kurt, the Bug Contest, the Unown puzzle, mail,
+  held items, shininess, gender, and the five cards of the GS boot cinema).
+  They are plain names, not a `gen2.` namespace, so if Red ever grows the
+  system the name is already right.
+- **Every Gen 2 seam is guarded** by `Runtime.wants` / `Runtime.wantsHook`, so
+  a boot with no mod subscribed allocates nothing at any of them.
+- **A mod is loaded on Gold only if it says so.** See `gen2compat` below.
+
+`src/mods/Schemas.lua` is authoritative for routing;
+`tests/engine/gate_gen2_mod_api.lua` holds this document to it.
+
+## Declaring which games a mod is for
+
+```json
+{
+  "id": "my_mod",
+  "name": "My Mod",
+  "version": "1.0.0",
+  "entry": "main.lua",
+  "api": 2,
+  "games": ["gen1", "gen2"]
+}
+```
+
+`games` is an optional array of version ids (`"red"`, `"blue"`, `"yellow"`,
+`"gold"`), generations (`"gen1"`, `"gen2"`, case-insensitive) or `"all"`.
+`src/mods/ModTargets.lua` resolves the tokens off `GameVersion.ORDER` and
+`GameVersion.generation`, so nothing anywhere restates the game list.
+`Manifest.validate` stores the resolved, ORDER-sorted ids on `manifest.games`
+and **derives** `manifest.gen2compat` from them, which is the one field the
+loader's gate reads.
+
+Nothing moves on disk for any of this. A mod is installed once, into
+`mods/<id>/`, and that directory serves every game: there is no `mods/gen1/`
+and no per-generation copy. Targeting is declared, not filed.
+
+`"gen2compat": true` is the legacy spelling and is still accepted. It is purely
+additive -- it *adds* the Gen 2 games to whatever `games` says -- so no shipped
+manifest can lose a game it already ran on. A manifest with neither key is Gen
+1 only, which is exactly what it always meant. An unknown token warns and is
+dropped under `api` 1 and refuses the manifest under `api` 2; a `games` array
+that names no game this engine knows falls back to the default rather than
+orphaning the mod; a non-array `games` is a hard error.
+
+Every token is enforced, per game. `Loader:_gateGeneration` gates on
+`ModTargets.supports(manifest, version, generation)`, the same call both mod
+surfaces make, so `"games": ["blue"]` really does not load on Red and the
+loader's skip line is the launcher's line, `For Blue, not Red`. A manifest with
+no `games` and no `gen2compat` still covers every Gen 1 game, so nothing
+written before the key existed changes behavior.
+
+On a Gold boot, a mod claiming no Gen 2 game is **not loaded at all**: no
+registrations, no subscriptions, no entry chunk. The manager still lists it,
+showing `ENABLED (NOT THIS GAME)` and the reason, and the player's enable flag
+is left alone so it comes straight back on Red.
+
+Both mod surfaces derive what they show from `ModTargets` rather than from
+their own copy of the rule. The launcher's mod panel carries a `Show for:` game
+chip row and a per-mod tag (`GEN 1`, `GEN 1+2`, `RED/GOLD`), greyed with `Not
+for this game` and the detail `For Gen 1, not Gold` when the mod does not run
+on the selected game; the in-game manager shows the same verdict as
+`ENABLED (NOT THIS GAME)` plus an inert `FOR GEN 1+2` row on the detail screen.
+The launcher asks the same question of a mod's dependencies: one whose hard
+dependency does not run on the selected game reads `Needs <id> (not for Gold)`,
+matching the loader's contagious skip.
+
+A separate overlay, `options.modsByVersion[version][id]`, holds each game's
+enable flag. The launcher shows a coloured Red / Blue / Yellow / Gold checkbox
+for every installed mod, and the loader and in-game manager read the same
+game-specific answer on the next boot. On the first launch after this feature,
+the existing shared state is copied to every game, so a mod that was enabled
+remains enabled everywhere; after that, changing one checkbox affects only
+that game. New mods still default to enabled on every game (experimental mods
+retain their explicit opt-in default).
+
+That is deliberate. Gold reimplements the battle engine, the overworld, the
+script VM and the save format, so a Gen 1 mod dropped into a Gold boot would
+find a small fraction of its call sites live. A mod that half-applies reads to
+a player as a broken mod. Not running is the honest state, and naming a Gen 2
+game is the author saying "I have tested this there".
+
+Adding a Gen 2 game does not opt out of anything on Gen 1, because `games` is a
+union: `["gen1", "gen2"]` covers everything it covered before. What does change
+is that the gate now runs on a Gen 1 boot too, so a manifest that names *only*
+Gen 2 games no longer loads on Red, Blue or Yellow. Say `["all"]` or list both
+generations if you want both.
+
+Two riders. **A hard dependency that does not run here takes the dependent down
+with it** (unless scoped to specific games, e.g.
+`dependencies: [{ id = "x", games = ["gen2"] }]`), as a skip rather than a
+failure and carrying the dependency's own wording (`depends on X, which does not
+run here (For Blue, not Red)`), so the whole chain has to cover the same games.
+And **the claim is yours, not the last word**: it is the manager's `TRY HERE ANYWAY` row that lets a player run a mod
+whose author never opted in, which is the only route for a mod written before
+the field existed. The override is per game -- `options.modsGen2[id]` is a
+`{ [version] = true }` table, so forcing a mod onto Red does not force it onto
+Gold, and a legacy `options.modsGen2[id] = true` reads as "the Gen 2 games",
+the only set it could ever have affected. It applies on the next boot; a forced
+mod loads normally and keeps a note saying it was never verified here. Where
+the choice cannot be persisted the manager says `COULD NOT SAVE` instead of
+promising a restart.
+
+If you are writing new code, still prefer the API: take the live game from
+`mod.game` (or the `game.ready` payload, or a `ui.*` hook's first argument) and
+the world from `mod.world`. Those are the names that mean the same thing in
+both games. What follows is for the mods that were written before Gold existed
+and reach past it.
+
+## Gen 1 module facades
+
+A mod with `engine_internals` reaches engine modules by name, and under Gold
+those names used to resolve to Gen 1 modules nothing instantiates -- so the
+patch landed on dead code and the mod was inert with no symptom but silence.
+
+On a Gen 2 boot, **a require made from a mod's own chunk is answered by an
+adapter**: the Gen 1 API, backed by Gen 2 internals. `src/mods/Gen2Compat.lua`
+is the table, `src/mods/Loader.lua`'s require shim is where the swap happens,
+and `tests/engine/gate_gen2_mod_facade.lua` holds both to it. Engine code is
+not affected -- the shim only substitutes when the calling chunk is outside the
+engine tree, so `src/render/PaletteFX.lua` still gets the real Gen 1 module on
+both generations.
+
+Fifteen names are served. **alias** means the adapter *is* the Gen 2 module, so
+a monkey-patch, a `rawset` sentinel and a `getmetatable(x) == M` check all land
+on the table Gold runs; **facade** means a translating wrapper over it.
+
+| the Gen 1 name a mod requires | kind | what it gets on Gold |
+| --- | --- | --- |
+| `src.core.Game` | facade | a live proxy onto the Game2 instance |
+| `src.world.OverworldController` | facade | over `src/world/gen2/World.lua`; `World:step` / `:interact` / `:interactBody` dispatch through it |
+| `src.world.Map` | alias | `src/world/gen2/Map.lua`, grown Gen 1's statics and instance methods |
+| `src.world.NPC` | alias | `src/world/gen2/Npc.lua`; `NPC.new` sniffs the Gen 1 argument order |
+| `src.pokemon.Boxes` | facade | over `src/core/gen2/Boxes.lua`, plus Gen 1's `COUNT` / `CAPACITY` / `ensure` / `active` / `deposit` |
+| `src.battle.BattleState` | facade | over `src/ui/gen2/BattleState.lua`, write-through |
+| `src.ui.PartyMenu` | facade | over `src/ui/gen2/PartyMenu.lua`, write-through |
+| `src.world.WorldAPI` | alias | `src/world/gen2/WorldAPI.lua` |
+| `src.world.PikachuFollower` | alias | `src/world/gen2/Follower.lua` |
+| `src.script.ScriptRunner` | facade | over `src/script/gen2/Vm.lua` |
+| `src.ui.OptionsMenu` | facade | over `src/ui/gen2/OptionsMenu.lua`, write-through |
+| `src.world.FieldDefaults` | facade | the `playerSprites` answer, and a named refusal for the rest |
+| `src.world.Collision` | facade | `DELTA` / `target` / `occupied` / `canMove` |
+| `src.ui.StartMenu` | facade | over `src/ui/gen2/StartMenu.lua`, write-through |
+| `src.ui.BoxMenu` | alias | `src/ui/gen2/PcMenu.lua` |
+
+Two entries in that table are not the pairing they look like.
+`src.ui.BoxMenu` resolves to `PcMenu`, not to `src/ui/gen2/BoxMenu.lua`: Gen 1's
+`BoxMenu` is Bill's PC *top menu*, whose Gold counterpart is `PcMenu`, while
+Gold's `BoxMenu` is the withdraw/deposit *list* Gen 1 builds inline. And
+`src.script.ScriptRunner` is served narrowly rather than fully: `scanLabels`
+and `validate` forward verbatim, with the default verb lookup swapped to
+`game.data.commands` so a script of Gen 1 built-ins cannot validate clean and
+then run as nothing, while the lifecycle half is a thin handle onto the one
+`world.vm` with `resume` and `update` refused rather than double-driving it.
+The `script.started` / `script.ended` / `script.command` seams are the
+supported route and already work on Gold.
+
+`src.script.Commands` and `src.ui.OptionRows` have **no** adapter and are the
+two names a require of which still lands in the boot error feed the manager
+shows, with the module named. Both load fine under Gold and both are traps: the
+first hands back 61 Gen 1 verbs none of which Gold can run, the second paints
+Red's four-box options chrome over Gold's single 18x16 one.
+
+`docs/preparing-your-mod-for-gen2.md` is the migration guide for an author
+working through this, and `python3 tools/modkit.py gen2check <id>` reports a
+mod's own findings against the coverage table below.
+
+Three rules the adapters keep, because a plausible wrong answer is worse than
+the module being missing:
+
+- **Live, never a snapshot.** A mod captures `require("src.core.Game")` at file
+  scope, before a save or a world exists. The facade is a proxy that reads the
+  live instance on every touch, so `Game.save` is nil during the entry chunk
+  and correct forever after. It aliases the two names Gold spells differently
+  (`Game.overworld` is `Game2.world`, `Game.writeOptions` is
+  `Game2:persistOptions`) and the one data table that was renamed
+  (`game.data.sprites` is `data.gen2Sprites`).
+- **A member with no backing says so.** `game.data.field` does not exist on
+  Gold, so it reads nil *and* logs once, naming the mods holding the facade.
+  `BattleState.newWild` is absent rather than invented, because a `newWild`
+  that took a species and a level would be a lie about what Gold's battle
+  screen is.
+- **One stable table for the run.** Where the Gen 2 arm can serve the name
+  outright the adapter *is* that module, so a mod's monkey-patch, its
+  `rawset` sentinel and its `==` idempotency check all land on the table Gold
+  actually runs.
+
+### What the adapter says it covers
+
+The adapter publishes its own coverage, versioned by
+`Gen2Compat.COVERAGE_VERSION` (1), and `modkit gen2check` consumes that table
+rather than a second copy of the same knowledge:
+
+```lua
+Gen2Compat.modules()                            -- the 15 names, sorted
+Gen2Compat.serves(name)                         -- boolean
+Gen2Compat.memberStatus(name, member)           -- "backed" | "warned" | "absent" | nil
+Gen2Compat.coverage(name)                       -- a fresh table per call:
+--   { module, kind = "facade"|"alias", target, members = { [name] = status },
+--     notes = { [name-or-topic] = "one line" } }
+```
+
+The status vocabulary is frozen at three values, and a member listed as both
+resolves to the weaker claim:
+
+| status | means |
+| --- | --- |
+| `backed` | present, and it does the Gen 1 job on Gold |
+| `warned` | present, answers nil or degrades, and names itself once with the mod attributed |
+| `absent` | deliberately not served; a nil read is the honest failure |
+
+Today that is 291 backed, 32 warned and 161 absent across the fifteen modules.
+`notes` keys are documentation topics rather than a member list -- dotted paths
+(`save.money`), field names (`warpAt`), hook names (`hook ui.pc.items`) and
+bare topics (`identity`, `iteration`, `rawset`) all appear there. `members` is
+the authoritative set, and a member it does not record is not a promise either
+way: on an alias it resolves to whatever the Gen 2 module has, on a
+write-through facade it falls to the Gen 2 class, on the `src.core.Game` facade
+it reads nil and says so, and on the `src.world.OverworldController` facade it
+reads nil silently.
+
+**The follower.** Gold's cart has no trailing companion at all, so
+`src/world/gen2/Follower.lua` is new Gen 2 code rather than a facade: the
+entity, the trail loop, and a `shouldSpawn` a mod replaces. `World:step` calls
+`Follower.update(game, world)` once per logic frame after the body, and
+`World:setMap` calls `Follower.onMapEntered` before it emits `map.entered` --
+the same two call sites `src/world/OverworldController.lua` gives the Gen 1
+arm, which is what makes a Gen 1 follower mod's wrappers tick.
+
+Vanilla never spawns one: `shouldSpawn` answers false until something replaces
+it. `Follower.setShouldSpawn(fn)` is the supported way, and it writes the same
+file-local the Gen 1 mods reach through `debug.setupvalue` on the upvalue named
+`shouldSpawn`, so the two cannot disagree.
+
+Two Gen 2 engine changes came with it, both general rather than follower-only:
+an entity with `passable` set never blocks a step (the Gen 1 name and meaning,
+`src/world/Collision.lua`), and `World:rebuildPeople` now preserves **guests** --
+anything in the people list it did not put there. A rebuild runs on every zoom
+and every time-of-day roll, so without that a follower vanished at the top of
+the hour.
+
+**What the facades cannot fix.** A mod that allow-lists version strings
+(`GameVersion.get() == "red" or ...`) excludes itself from Gold by construction,
+and no adapter should special-case it. Neither is a Gen 1 screen id: Gold's
+builtins carry a `Gen2` prefix, so a mod matching `id == "BoxMenu"` matches
+nothing. A write to a field on a live Gen 2 menu instance is inert where Gen 1
+read it back (`menu.onSwitch`, `menu.swapFrom`, `StartMenu`'s box geometry),
+and `map.warpAt` is a name collision rather than a rename -- Gen 1's is a table
+keyed by cell, Gold's is a method, so indexing or iterating it raises. All of
+these are mod-side edits, each with a route that works on both generations;
+`docs/preparing-your-mod-for-gen2.md` walks through them.
+
+## What works on Gold today
+
+**Screens.** The `screens` registry serves both generations. Gold's screens
+are registered under `Gen2`-prefixed ids so a mod that replaces Gold's party
+menu does not also replace Red's; `Screens.GEN2_IDS` in `src/ui/Screens.lua`
+is the full list. Every screen Gold opens goes through an id, including the
+boot cinema and the START menu.
+
+**Asset overrides.** `overrides/` shadowing and asset transforms work
+unchanged: Gold's screens load art through `src/render/Assets.lua`, the same
+choke point Gen 1 uses.
+
+**Content registries at the shared path.** `pokemon`, `moves`, `items`,
+`type_chart`, `strings`, `font`, `screens`, `commands`, `tokens`,
+`growth_rates`, `battle_sprite_scales`, `render_pipelines`, and the audio
+family (`audio`, `music`, `sfx`, `cries`, `map_songs`). These keep their Gen 1
+target path, so one mod source targets both generations.
+
+The last two are the newest and each carries one caveat worth stating before
+you write against it:
+
+- **`battle_sprite_scales`.** `src/ui/gen2/BattleState.lua:imageScale` walks
+  the merged table for a record whose `path` matches the pic being drawn,
+  skipping the registry's own `_owners` row, and `picScale` falls through to
+  the species record's `battleScaleFront` / `battleScaleBack` after it -- the
+  same image-then-species-then-default order Gen 1 resolves in. Because the key
+  is the asset path it also reaches the pics that are nobody's species: the
+  player's trainer back, the DUDE's, an opponent's frontpic. The **default**
+  differs and is not a registry record either side: Red's 32x32 back pics draw
+  at 2x, Gold's 48x48 ones fill their 6x6 box at 1x, so a scale that looks
+  right on Red is twice as large on Gold. At any scale the pic stays centred in
+  its box and standing on the same ground line.
+- **`render_pipelines`.** `src/core/Game2.lua:load` installs
+  `src/render/Pipelines.lua` on Gold's dataset *after* `mods:load`, so the
+  merged table is the one it walks, and `Game2:draw` composites the
+  whole-frame half through `Pipelines.wantsPresent` / `Pipelines.present` with
+  the Gen 1 ctx keys (`width`, `height`, `scale`, `dpi`, `dpiX`, `dpiY`). The
+  **`drawWorld` half is inert on Gold**: its overworld draws straight to the
+  window rather than into a canvas the way `src/world/OverworldController.lua`
+  hands one to `Pipelines.drawWorld`. A drawWorld-only pipeline is not left
+  switched on and drawing nothing -- `Game2:load` retires a restored level for
+  one, leaving `options.pipelines` untouched so the mode comes back the day
+  Gold grows a world canvas. Gold also has no OPTION row for a pipeline
+  (`Pipelines.rows` is read only from `src/ui/OptionsMenu.lua`), so a Gold
+  player reaches one by its `hotkey`.
+
+**Content registries at a Gen 2 path.** `maps`, `tilesets`, `sprites`, `text`,
+`encounters`, `trainers`, `palettes`, `icons`, `battle_anims`, `constants`,
+`statuses`, `move_effects`, `item_effects`, `balls`, `ai_classes` and
+`evolution_methods`. Same registry name, same verbs, a Gen 2 table underneath
+(`data.gen2Maps`, `data.gen2Encounters`, `data.gen2Statuses`, ...).
+`src/core/Game2.lua` loads the extracted ones into `game.data` before it
+calls `mods:load`, and every consumer takes them by reference and never
+copies, so what a mod merges is what the game walks: a registered map is a map
+Gold can warp into, a patched tileset is the one `Map.new` reads, a patched
+encounter table is the one the grass rolls.
+
+The battle-rule six are the newer half and work slightly differently: there is
+no table on disk for them at all. They come into existence *as* the merge, and
+each consumer reads a record through a lookup that falls back to its own module
+records when no loader ran, so a mod-free Gold boot behaves identically:
+
+| registry | who reads it |
+| --- | --- |
+| `statuses` | `Battle.statusRecordFor` / `statusPenaltyFor`, `Catching.statusBonus`, `ItemEffects.healClassOf` |
+| `move_effects` | `Battle.moveEffectRecordFor` (`useMove`'s dispatch) |
+| `balls` | `Catching.recordFor` |
+| `ai_classes` | `Ai.layersFor` (the ten `scoring.asm` passes, plus mod layers) |
+| `evolution_methods` | `Evolution.methodFor` |
+| `item_effects` | `ItemEffects.recordFor` / `partyAction` |
+
+`src/mods/Builtins.lua` seeds those six with **Gold's** records under Gen 2
+rather than Red's. It has to: both games call it `GREAT_BALL`, and Red's record
+carries no `multiplier`, so seeding Red's would leave Gold's x1.5 reading nil.
+
+**Content registries that exist because Gold does.** Six systems Red has no
+counterpart for, so there is no Gen 1 table to share and none of these carries
+a Gen 1 target at all. The routed Gen 2 path is their only home, and
+`Schemas.GEN1` gates them on a Red boot the way `Schemas.GEN2` gates
+`map_scripts` on a Gold one -- reported, not silently merged.
+
+| registry | id space | who reads it |
+| --- | --- | --- |
+| `held_items` | item ids | `ItemEffects.heldItemFor`; the merged rows are written back onto `data.items` for `Battle:itemDef` |
+| `phone_contacts` | `PHONE_*` (`data.gen2Constants.phoneContactOrder`) | `Phone.useRegistry`, folded onto the contact table |
+| `decorations` | `"deco:<n>"` | `Decorations.attributes`, the single read point for an attribute row |
+| `apricorns` | apricorn item ids | `Apricorns.useRegistry`, which rebuilds all three lookups and Kurt's menu order |
+| `landmarks` | `LANDMARK_*` | `Nests.landmarkId` / `Nests.landmark`, which resolve a map header's landmark byte |
+| `radio_channels` | station ids | `MapRadio.channelRecord`, which puts a registered station on the dial |
+
+`Game2:load` calls `Phone.useRegistry`, `Decorations.useRegistry`,
+`Apricorns.useRegistry` and `ItemEffects.applyHeldItems` immediately after
+`mods:load`, so the merge is live before the first frame. `landmarks` and
+`radio_channels` need no such call: their consumers take `data` at call time.
+
+`landmarks` merges onto the cache's own `gen2Landmarks.landmarks` and
+`held_items` onto the view `Game2` builds from `data.items`, so both fold
+against the vanilla row -- a `register` for an existing id collides, a
+`patch` stacks. The other four come into existence as the merge, seeded from
+their module's literals by `src/mods/Builtins.lua`.
+
+Four honest limits on that surface:
+
+- `held_items` reaches the battle by being written back onto `data.items`, so a
+  held row for an id with no `data.items` record lands nowhere. To invent a
+  held item, register the `items` record too. The write-back is a diff against
+  a pre-merge snapshot, which is what lets `items` and `held_items` compose
+  instead of one reverting the other.
+- `decorations` ids are `"deco:<n>"`, not `DECO_*` names: the cart's decoration
+  constants are a bare `const_def` block with no name table behind them, so
+  there is nothing in the ROM to spell them by. `battle_anims` addresses its
+  unnamed rows the same way. `n` is the attribute row's index, which is
+  `wMenuSelection`.
+- `phone_contacts` does not register the four `PHONE_UNUSED` `const_skip` holes
+  (contact bytes 8, 9, 10 and 25). The manifest gives all four the same id, and
+  one id cannot key four rows. They stay copies of the wrong-number filler,
+  which is what the cart does with them.
+- `radio_channels` and `phone_contacts` register *content*, not new UI: a
+  registered station gets a dial position and a name, and a registered contact
+  gets a row the Pokegear indexes, but neither invents a screen.
+
+**Record shapes.** A registry whose Gen 2 records genuinely differ carries a
+Gen 2 schema beside its Gen 1 one (`gen2Fields` / `gen2Keys` / `gen2Write` in
+`src/mods/Schemas.lua`, resolved by `Schemas.shapeFor`). The registry name, the
+verbs and wherever possible the ids stay shared; only the record changes. The
+differences an author meets:
+
+- **`pokemon`.** Gen 2 splits `special` into `specialAttack` /
+  `specialDefense`, names the level-up table `levelMoves` and the pic size
+  `picSize`, has no separate `level1Moves`, and points an evolution at `into`
+  rather than `species`. It also carries the breeding block (`eggGroups`,
+  `eggMoves`, `eggSteps`, `genderRatio`) and the wild held-item pair.
+- **`encounters`.** The id is the encounter *kind*, not the map:
+  `mod.content.encounters:patch("grass", { ROUTE_29 = { rates = { NITE = 40 } } })`.
+  A map's row carries a `rates` set per time of day and one slot list.
+  `fishGroups`, `trees` / `treeSets`, `rocks`, `bugContest` and `roamMaps` are
+  ids of their own.
+- **`trainers`.** The id is the trainer *class*, and the record is
+  `{ name, index, attributes, baseMoney, encounterMusic, trainers, items }`,
+  with one entry per named trainer of the class. The registry writes one level
+  in, into `data.gen2Trainers.classes`, so the call shape is unchanged.
+- **`icons`.** Two id forms in one registry, routed by the `ICON_` prefix a
+  sheet name carries: a species id names an assignment (a string, the sheet's
+  name), an `ICON_*` id names a sheet.
+- **`palettes`, `battle_anims`, `constants`.** The id is a subtable of the
+  target: `pokemon` / `trainers` / `bg` / `objects` / `roofs` for palettes,
+  `scripts` / `moves` / `objects` / `framesets` / `oamsets` / `gfx` for
+  battle_anims, and one of Gold's 42 ordered ROM name lists (plus `mapGroups`,
+  `trainerClassMembers`, `types`) for constants. Those lists are ordered and
+  position *is* the id a script byte resolves through, so they replace rather
+  than append.
+
+Four more id-space notes, because the records at those paths came out of a
+Gen 2 ROM:
+
+- Gold's `text` ids are ROM pointer strings such as `"55:4067"`, not the
+  `TEXT_*` names Red uses. `override` them by pointer; there is no name table.
+- A Gen 2 tileset carries its walkability as `collision` where Gen 1 says
+  `walkable`. Both fields validate; only `collision` is read on Gold.
+- A Gen 2 warp row carries `destGroup` / `destMapNum` beside the `destMap` /
+  `destWarp` pair Gen 1 also has. Both are optional in the shared schema, so a
+  Gen 1 warp row and a Gen 2 one both validate, and patching one of Gold's own
+  maps does not mean restating the ROM's map-group numbers.
+- Gold writes `"burn"` / `"sleep"` into `mon.status` where Red writes `BRN` /
+  `SLP`. The `statuses` registry is the same registry; only the ids differ, and
+  they have to.
+
+**`mod.commands`.** Works on Gold. `src/script/gen2/Vm.lua` runs the cart's own
+bytecode, so there is no opcode byte to hand a mod -- the seam is a row the
+cart cannot write. `Opcodes.MOD_COMMAND` (`"modcommand"`) is an op *name* with
+no byte behind it, and the VM dispatches it through the same merged
+`data.commands` table Gen 1's runner resolves by name. Two row shapes reach it:
+
+```lua
+{ op = "modcommand", verb = "mymod:shake", args = { 4, 2 } }   -- native
+{ "mymod:shake", 4, 2 }                                        -- Gen 1 row
+```
+
+The second is the Gen 1 row shape verbatim, so one row list can serve both
+games as long as every row in it is the mod's own verb. The handler is called
+`fn(ctx, unpack(args))` with `ctx.vm` where Gen 1 has `ctx.runner`; it may
+block on `ctx.vm:showText` / `:waitFrames`, and its return value speaks Gen 1's
+control vocabulary (`"end"`, a row number, or nil). A missing or raising verb
+is warned once per name and the rest of the list still runs. The engine's own
+Gen 1 verbs are **not** seeded on Gold: a row-list verb handed Gold's ctx would
+find no runner on it, so `data.commands` under Gen 2 is the mod verbs alone.
+
+**`mod.save`, `mod.options`, `mod.log`, `mod.assets`, `mod.find`, exports.**
+Generation-agnostic; nothing to adapt.
+
+**`mod.world`.** Same method set, resolved against Gold's world
+(`src/world/gen2/WorldAPI.lua`). Two differences show through and are
+documented on the module: Gold's world is not a stack state, and Gen 2 event
+flags are numeric ids into `wEventFlags` rather than string keys.
+`mapOverview` returns the same read-only terrain, tile-shading, and marker
+shape, using Gold's live object masks and event flags to omit collected items.
+`spawnNpc` / `removeNpc` append onto the map def's own object list, the way the
+Gen 1 arm does, so a spawned actor is pooled, drawn, walked and talked to like
+an extracted one and survives a map reload; it is not serialized, so a mod
+respawns on `map.entered`. `queueScript` takes a small allowlist of verbs Gold
+has its own entry points for (`start_battle "wild" species level`, `warp`,
+`text`, `setflag`, `clearflag`) and refuses a list containing anything else
+**by name, before the first row runs**, so a mod never gets a half-run queue.
+`marchInPlace` still has no Gen 2 equivalent (the Gen 2 movement stream has no
+byte for it) and returns `nil, reason` rather than approximating one.
+`availableFieldActions` and `useFieldAction` expose the same contextual field
+item and move records in both games. Gold extends the shared ids with its own
+`headbutt`, `whirlpool`, `waterfall`, `sweet_scent`, and `squirtbottle`
+actions. Each engine keeps ownership of its inventory, badges, terrain,
+surfing, bike, fishing, and field-move rules.
+
+**Hooks and events that fire on Gold.** Every name below is the Gen 1 name
+carrying the Gen 1 payload keys, because Gold's call sites reuse them rather
+than defining a parallel vocabulary; where Gen 2 carries more, the payload
+gains a field instead of the name gaining a prefix.
+
+- *Engine-wide, from the shared modules:* `game.ready`, `screen.pushed`,
+  `screen.popped`, `screen.render_visible`, `music.started`, `music.stopped`,
+  `music.select`, `music.volume`, `sound.played`, `zoom.range`,
+  `assets.transformed`, `mods.loaded`, `mod.options_changed`.
+- *Overworld (`src/world/gen2/`):* `map.entered`, `map.exited`,
+  `map.reloaded`, `player.warped`, `world.stepped`, `world.interacted`,
+  `world.npc_spawned`, `world.trainer_engaged`, `world.blacked_out`,
+  `world.block_replaced`, `world.boulder_moved`, `world.tod_changed`,
+  `world.object_toggled`, `flag.changed`; hooks `warp.destination`,
+  `movement.collision`, `movement.speed`, `encounter.roll`,
+  `encounter.species`, `encounter.fishing`, `world.tod`, `map.palette`,
+  `fieldmove.eligibility`. `flag.changed` carries the numeric `wEventFlags`
+  id under Gen 1's `name` key, which is the one payload difference the
+  numeric flag space forces.
+- *Menus (`src/ui/gen2/`):* `ui.start_menu.items`, `ui.title_menu.items`,
+  `ui.options.rows`, `ui.party.submenu`, `ui.naming.grid`, `ui.pc.items`,
+  `ui.list_menu`, `transition.style`. `ui.list_menu` covers Gold's script
+  menus (`ScriptMenu.lua`); the `Chrome.List` widget the START and title
+  menus draw with does not raise it yet, so those two are composed through
+  their own hooks only.
+- *The Oak speech (`src/ui/gen2/OakSpeech.lua`):* `intro.oak_speech.started`,
+  `intro.oak_speech.step`, `intro.oak_speech.answered`,
+  `intro.oak_speech.finished`, and the `intro.oak_speech.build` hook. Gold has
+  a real Oak speech, so it is the same extension point rather than a second
+  one: same names, same payload keys, same moments in the sequence. The beats
+  are a data table with the same step vocabulary (`say` / `pic` / `name` /
+  `choice` / `yesno` / `shrink` / `fn`, plus Gold's own `initclock` and
+  `demo`), and the step *ids* match Gen 1's wherever the moment is the same --
+  `oak_welcome`, `demo_mon`, `world_spiel`, `ask_player_name`, `name_player`,
+  `legend`, `shrink` -- so `ModUI.insertStepBefore(steps, "name_player", ...)`
+  lands in the right place in both games. The two ids with no Gen 1
+  counterpart are Gold's own beats, `init_clock` (the `farcall InitClock` the
+  speech opens with) and `oak_study` (the return to Oak for `_OakText5`). Gold
+  has no rival-naming or name-confirmation beats, so it raises no anchors for
+  them: the rival is named by `CopScript` in `maps/ElmsLab.asm`, hours later.
+- *Battle (`src/battle/gen2/`):* `battle.started`, `battle.ended`,
+  `battle.turn_started`, `battle.turn_ended`, `battle.move_used`,
+  `battle.damage_dealt`, `battle.fainted`, `battle.status_inflicted`,
+  `battle.battler_switched`, `battle.ball_thrown`, `battle.exp_gained`,
+  `pokemon.level_up`, `pokemon.move_learned`; hooks `battle.damage`,
+  `battle.crit`, `battle.accuracy`, `battle.turn_order`,
+  `battle.enemy_action`, `battle.run`, `battle.exp_award`, `exp.gain`,
+  `catch.rate`, `trainer.party`, `battle.overlay`, `battle.low_health_alarm`,
+  `battle.catch_exp`, `battle.bottom_ui_visible`,
+  `battle.status_hud_visible` and `battle.move_grid_navigation`. One payload
+  difference: Gen 1's vanilla
+  `battle.low_health_alarm` link reads `ctx.battle.data`, and Gold's battle
+  screen has no `.data` field, so the Gen 2 site **adds** `ctx.data` beside the
+  Gen 1 keys. A mod that calls `nextFn` is unaffected; one that reaches through
+  `ctx.battle.data` instead gets nil on Gold.
+- *The catch and the evolution:* `pokemon.caught`, `pokemon.evolved`; hook
+  `evolution.check`. `src/ui/gen2/BattleState.lua:pushCaught` emits
+  `pokemon.caught` once the mon is in the party or the box, and
+  `src/core/gen2/Evolution.lua` emits `pokemon.evolved` from `apply` and wraps
+  each row's decision in `evolution.check`. The hook passes `data` where Gen 1
+  passes `game`; positions 2-4 (mon, row, trigger) match.
+- *The frame (`src/core/Game2.lua`):* hooks `input.step`, `input.pointer`,
+  `render.zones`, `render.compose`, `render.output_enabled`, `render.output`,
+  `render.letterbox`, `render.hud`, `render.viewport`, `render.window`. Each sits
+  at the same moment `src/core/Game.lua` and `src/render/Renderer.lua` raise it
+  -- the logic tick before the pad is read, a pointer the touch overlay gets
+  first refusal on, the palette zone list handed to the present pass, the
+  composed frame before GBCFX, the letterbox, and the finished playfield rect
+  -- and carries the same payload.
+  `render.hud`'s `gameX` / `gameY` really is where Gold's dialogue boxes and
+  menus land, because `Chrome.fitScale` / `fitOrigin` and `World:fitScale`
+  compute the same number. `render.zones` is handed `nil` in GBC mode (Gold
+  computes no zone of its own there) and the engine's own one-rect list in
+  CLASSIC mode; a rect that clamps to nothing is skipped rather than throwing,
+  which is what `src/render/Renderer.lua:scissorClamped` does on the Gen 1 side.
+- *Sprites (`src/pokemon/Sprites.lua`, shared):* `pokemon.sprite`,
+  `pokemon.icon` and `player.sprite`. `pokemon.icon` is reached from
+  `src/ui/gen2/PartyMenu.lua` through the shared module, so it is one call site
+  serving both games. `player.sprite` is raised by `Sprites.playerPic`, which
+  Gold's battle back pic (`src/ui/gen2/BattleState.lua`), Hall of Fame and
+  intro call with an already-resolved path: Gold's trainer art is not in
+  `field.playerPics`, so the path is found first and the hook raised over it,
+  with the Gen 1 `ctx` keys (`side`, `kind`, `demo`, `battle`, `data`)
+  unchanged. The Gen 2 trainer card is the one player-art read still outside
+  it: its portrait is a tile sheet that also carries the frame tiles, not a
+  swappable pic.
+  `pokemon.sprite` has a second site of its own in
+  `src/ui/gen2/BattleState.lua`, which adds `letter` (Unown) and `shiny` to the
+  Gen 1 ctx keys -- both concepts Red does not have.
+- *Save and the script VM:* `save.created`, `save.loaded`, `save.loading`,
+  `save.writing`; hooks `save.write`, `save.new_game`, `script.command`, and
+  the `script.started` / `script.ended` pair off `src/script/gen2/Vm.lua`.
+  `script.command` reports a mod's own row under the name `"modcommand"` with
+  the row's real operands, and may rewrite them, on the same path it wraps a
+  cart row.
+
+## New in Gen 2
+
+These have no Gen 1 analogue -- Red has no friendship byte, no day care egg,
+no Pokegear, no radio, no held items -- so they are the only places a new name
+is justified. They are **live**, guarded by `Runtime.wants` /
+`Runtime.wantsHook`, and each is driven through a real bus by
+`tests/engine/gen2_new_seams.lua`.
+
+### Events
+
+| event | raised from | payload |
+| --- | --- | --- |
+| `happiness.changed` | `Happiness` (`ChangeHappiness`, `StepHappiness`) | `mon`, `event`, `reason` (`"event"` / `"step"`), `delta`, `from`, `to` |
+| `breeding.egg_created` | `Breeding` (`DayCare_InitBreeding`) | `egg`, `mother`, `father`, `compatibility`, `stepsToEgg` |
+| `egg.hatched` | `Breeding` | `mon`, `egg`, `slot`, `species`, `nickname` |
+| `phone.call_received` | `PhoneRing.script` | `call`, `contact`, `name`, `className`, `special`, `scriptKey` |
+| `clock.day_changed` | `Clock` | `day`, `previous`, `reason` |
+| `pokerus.infected` | `Pokerus` | `party`, `slot`, `mon`, `strain`, `days`, `source` |
+| `roamer.moved` | `Roamers` | `index`, `slot`, `species`, `from`, `to`, `reason` |
+| `roamer.encountered` | `Roamers` | `index`, `slot`, `species`, `level`, `mapId` |
+| `apricorn.converted` | `Apricorns` (Kurt) | `apricorn`, `ball`, `event` |
+| `bug_contest.scored` | `BugContest` | `mon`, `score`, `place`, `results` |
+| `unown.unlocked` | `Unown` (`UpdateUnownDex`) | `letter`, `name`, `word`, `count` |
+| `radio.channel` | `MapRadio` | `station`, `channel`, `name`, `source` |
+| `mail.written` | `Mail` | `entry`, `slot`, `mon`, `message`, `author`, `source` |
+| `mail.read` | `Mail` | `entry`, `message`, `author`, `top`, `bottom` |
+| `intro.boot.copyright` | `CopyrightSplash:enter` | `screen`, `game` |
+| `intro.boot.gamefreak` | `GameFreakPresents:enter` | `screen`, `game` |
+| `intro.boot.movie` | `GoldSilverIntro:enter` | `screen`, `game` |
+| `intro.boot.movie_ended` | `GoldSilverIntro:finish` | `screen`, `game`, `skipped`, `frames` |
+| `intro.boot.title` | `TitleState:enter` | `screen`, `game` |
+
+The four `intro.boot.*` cards are the GS boot cinema, and they are the one part
+of Gold's intro with no Gen 1 moment to share a name with: Red boots into
+`IntroMovie` with no copyright card, no GAME FREAK splash and no attract movie.
+The Oak speech immediately after them is the opposite case and reuses
+`intro.oak_speech.*` verbatim (see the shared table above).
+
+Each card raises its name the frame it comes up, because that is the moment a
+mod can act on. Only the movie has an `_ended` name, and only because it
+carries a fact nothing downstream does -- `skipped` is the difference between a
+player who watched all 2335 frames and one who pressed START. The other three
+cards chain straight into the next card, whose own event is their end.
+
+`delta` on `happiness.changed` is `to - from`, not the table's column, because
+the 0 and $ff carry clamps are part of what the cart applied: a mon at 254
+gaining "5" gained 1.
+
+`clock.day_changed` compares against a process-local latch, so the first read
+after a boot has nothing to compare against and raises nothing. That is by
+design; it is a day *change*, not a day report.
+
+`unown.unlocked` is raised from `UpdateUnownDex` -- a form first entering the
+`#DEX` list -- not from the four `ENGINE_UNLOCKED_UNOWNS_*` puzzle flags. Those
+flags are written by the cart's own `setflag`, so there is no Lua transition at
+the puzzle solve to hang a second event on yet.
+
+`mail.read` rides `Mail.lines` with a per-struct latch, because the read page
+redraws every frame. The latch is re-armed by `Mail.get` / `Mail.mailbox`,
+which is how both readers pick the letter they are about to open, so reopening
+the same letter raises a second event.
+
+### Hooks
+
+| hook | wraps | ctx | vanilla answer |
+| --- | --- | --- | --- |
+| `held_item.trigger` | `Battle:heldEffect` | `battle`, `mon`, `item`, `def`, `effect`, `parameter`, `trigger` | `ctx.effect, ctx.parameter` |
+| `breeding.compatibility` | `Breeding.compatibility` | `data`, `mon1`, `mon2`, `dayCare` | the vanilla byte |
+| `phone.contact_list` | `Phone`'s `wPhoneList` read | called `(save, list)`, the shape the other list hooks use | the same list |
+| `shiny.roll` | `Mon` | `dvs`, `species`, `def`, `level` | the DV-derived boolean |
+| `gender.roll` | `Mon` | `def`, `dvs`, `ratio`, `species`, `level` | the DV-derived gender |
+
+`held_item.trigger` is one hook over eight call sites, because on the cart
+those eight *are* one routine (`GetUserItem` / `GetOpponentItem` loading b and
+c, and the caller comparing b against the `HELD_*` it cares about). `trigger`
+says which comparison is about to happen: `"priority"` (Quick Claw),
+`"damage"` (Scope Lens and the type-boost family), `"endure"` (Focus Band),
+`"flinch"` (King's Rock), `"accuracy"` (BrightPowder), `"confuse"`,
+`"residual"` (the end-of-turn Leftovers / Berry / cure arm), and `"check"` for
+any other read. Return nil to make the item do nothing at that trigger, or
+another `HELD_*` name to substitute one -- every call site compares against a
+name, so substitution is the whole mechanism.
+
+`held_item.trigger` wraps the *read*, so a mod can suppress or substitute an
+effect from any item. Defining a **new** held item is the `held_items`
+registry's job, and the two compose: register the row, then steer it from the
+hook.
+
+`phone.contact_list` refuses an answer of the wrong length or with an unknown
+contact id (unknown ids blank to 0 on purpose, so the Pokegear never indexes a
+nil). It reorders and blanks the ten save slots; registering a contact id the
+game does not know is `phone_contacts`' job.
+
+`shiny.roll` does not override a forced-shiny battle (`opts.shiny`), which is
+how the cart's own scripted shiny Gyarados stays shiny.
+
+## Registries with no Gen 2 home
+
+Writing to one of these while Gold is running takes the write, drops it, and
+reports it once per mod into the same error feed the manager shows. It is not
+fatal: a mod that supports both generations registers its Gen 1 content
+unconditionally and still loads the half that applies. The report is worded
+from the boot's own generation, because the gating runs both ways.
+
+`rulesets`, `transitions`, `field`, `text_pointers`, `link_fields`,
+`map_scripts`.
+
+`Schemas.GEN2` in `src/mods/Schemas.lua` is the authoritative table, and
+`tests/engine/gate_gen2_mod_api.lua` holds it to the catalog.
+
+The list used to have three causes behind it and now has one. "No Data path
+exists" closed when the overworld tables stopped loading off disk into World
+fields. "The shape differs" closed when a registry gained the option of
+carrying a Gen 2 record schema beside its Gen 1 one. What is left is one cause:
+
+**Gold reimplements the system without reading a registry.** The Gen 1 target
+is still built and merged into, but nothing in a Gold boot ever looks at it, so
+routing the registry would be a merge into a table with no reader -- exactly
+the silent no-op the gate exists to prevent. Closing one of these is a consumer
+change in the Gen 2 module first and a routing row second:
+
+- `rulesets`: no Gen 2 ruleset dispatch exists.
+- `transitions`: Gold draws its own battle intro
+  (`src/ui/gen2/BattleTransition.lua`), and its `STYLES` is a boolean *set* of
+  the four cart wipes (`spin`, `speckle`, `zoom`, `sine`) rather than the
+  `{ frames, draw, sound, flash }` record this registry carries. There is no
+  styleDef lookup for a registered id to reach, so a mod style would fail the
+  `STYLES` membership test and fall back to vanilla -- routing it would be the
+  silent no-op, not the fix.
+- `field`: the Gen 1 overworld's data grab bag. Gold's equivalents live in
+  `data.gen2Maps` and the VM's own tables.
+- `text_pointers`: Gen 1's `TEXT_*` indirection. Gold's text *is* pointers.
+- `link_fields`: link play is Gen 1 only.
+- `map_scripts`: `data.gen2Scripts` is the cart's bytecode pool keyed by ROM
+  pointer, and a Lua row list merged into it is not something
+  `src/script/gen2/Vm.lua` can run. Routing it needs a Gen 2 side dispatcher in
+  `World`, not just the verb table `mod.commands` already has. The
+  `script.started` / `script.ended` / `script.command` seams do fire, so a mod
+  observes and can veto a script it cannot yet author whole.
+
+Four of this list closed after it was written, and how they closed is the
+pattern for the rest:
+
+- **`growth_rates`** now routes to the SHARED Gen 1 target. Gold's curves are
+  coefficient rows in the extracted `pokemon.lua`, so `src/mods/Builtins.lua`'s
+  Gen 2 registrant wraps each as the `{ expForLevel }` record Gen 1's registry
+  uses, and `src/battle/gen2/Mon.lua:growthFor` is the one accessor all six
+  readers go through (`Mon` twice, `BattleState`, `SummaryMenu`, `Breeding`,
+  `ItemEffects`). One record shape, one id space, one mod source for both
+  games. Because it is routed, the `pokemon` schema's `growthRate` reference is
+  now checked rather than skipped, and it resolves: both sides say
+  `GROWTH_MEDIUM_SLOW`.
+- **`tokens`** was on the list by mistake rather than by cause. `TextBox.new`
+  runs `TextBox.substitute` on every box in both generations and `substitute`
+  reads `game.data.tokens`, so the shared target was live on Gold the whole
+  time. A `{NAME}` a mod registers expands in the world, the menus and the VM's
+  pages alike.
+- **`battle_sprite_scales`** closed consumer-first, the `growth_rates` way:
+  `src/ui/gen2/BattleState.lua` grew `imageScale` / `picScale`, a faithful
+  mirror of Gen 1's `BattleState.imageBattleScale` / `resolveBattleScale` down
+  to skipping `_owners` and the image-then-species-then-default order, so the
+  registry now routes to the SHARED Gen 1 path and one record serves both
+  games. Only the default is generation-specific, and neither side reads that
+  from the registry.
+- **`render_pipelines`** closed because the reader moved, not the registry:
+  `src/core/Game2.lua:load` installs `src/render/Pipelines.lua` on Gold's
+  merged dataset after `mods:load` and `Game2:draw` composites `present`. The
+  `drawWorld` half is still inert, which is why this one is worth reading the
+  caveat above for -- it is routed on the strength of the half that works, and
+  Gold retires a drawWorld-only level rather than pretending.
+
+## Hooks and events Gold does not raise yet
+
+Gold has its own draw path, intro, evolution and sprite lookups, so the call
+sites in those Gen 1 modules are not on Gold's path. The names are not taken
+and not reserved for Gen 1: when a Gen 2 call site lands it uses the existing
+name and the existing payload, plus fields where Gen 2 genuinely carries more
+(the split special stats, held items on a trainer roster).
+
+The list is much shorter than it was. What is outstanding, in descending value:
+
+- `trainer.before_battle`: Gold constructs and pushes its trainer battle in
+  `src/world/gen2/World.lua:startBattle`, which does not yet expose a deferred
+  preparation boundary or a battle-local player-party view. Gen 1 mods can use
+  the hook documented in `docs/modding.md`; do not claim Gold compatibility
+  when that selection is required.
+- `pokemon.before_give` / `pokemon.received`: Gold has no give-mon seam of its
+  own yet.
+- `link.*` and `trade.completed`: a Gold boot offers no link menu at all. The
+  Gen 2 fingerprint and handshake exist (`src/link/Fingerprint.lua` hashes a
+  Gen 2 surface and a cross-generation pairing is refused by name), but nothing
+  in `src/ui/gen2/` opens onto the protocol, so these raise nowhere.
+
+Four groups that used to sit here have since landed and moved to the shared
+table above: the frame seams (`render.compose` / `render.hud` /
+`render.letterbox` / `render.zones`, `input.step` / `input.pointer`), the three
+battle seams (`battle.overlay`, `battle.low_health_alarm`,
+`battle.catch_exp`), the two sprite lookups (`pokemon.sprite`,
+`pokemon.icon`), and the catch/evolution trio (`pokemon.caught`,
+`pokemon.evolved`, `evolution.check` -- `src/ui/gen2/BattleState.lua` emits
+`pokemon.caught` from `pushCaught` once the mon is in the party or the box, and
+`src/core/gen2/Evolution.lua` emits `pokemon.evolved` from `apply` and wraps
+each row's decision in `evolution.check`).
+
+Three partial coverages worth knowing about, because "the hook exists" is not
+the same as "the hook sees everything":
+
+- `encounter.roll` / `encounter.species` are wired into the grass/water step,
+  `randomwildmon`, the Bug Contest and SWEET SCENT, but **not** into
+  `World:tryHeadbutt`, `World:rockMonEncounter` or `Roamers.checkEncounter`.
+  Those three read row shapes that are not `{ species, level }` slot lists, so
+  a mod that reskins encounters misses headbutt trees, rock smash and the
+  roamers.
+- `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 yet resolved at the real throw site.
+- Three Gold UI files carry their own copy of the status HUD labels the merged
+  `statuses` records now hold as `hudLabel`, so a mod status shows no label in
+  the battle HUD, the party menu or the summary page until they read
+  `Battle.statusRecordFor(data, status).hudLabel`. The values are identical
+  today, so nothing vanilla is affected.
+
+## Gen 2 tables with no registry
+
+`Game2:load` assigns 24 `data.gen2*` tables and 12 of them are registry-backed,
+so twelve sit in `game.data` on a Gold boot with no registry pointing at them:
+`gen2Marts`, `gen2Roofs`, `gen2StdScripts`, `gen2EventTables` (the phone book,
+in-game trades, elevator labels, decoration descriptions), `gen2InitialEvents`,
+`gen2Pokedex`, `gen2MenuGfx`, `gen2Intro`, `gen2Credits`, `gen2Diploma`,
+`gen2Trade`, and `gen2Scripts` (which the `map_scripts` registry does reach, so
+it is the one of the twelve that is not out of reach). Naming registries for the
+rest is new API surface rather than a routing change, so it is deliberately not
+done yet.
+
+## Testing a Gen 2 mod
+
+Static first. `gen2check` reads the manifest, scans every `.lua` the package
+carries and cross-references what it finds against the coverage table above:
+
+```sh
+python3 tools/modkit.py gen2check my_mod            # or a path
+python3 tools/modkit.py gen2check my_mod --notes    # + the caveat on each backed member
+```
+
+It reports one of `will load`, `will load but degrade` or `will not work`, with
+a `MK4xx` finding per site and an `unresolved:` note, carrying a file and a
+line, for every reach a static scan could not follow. Exit 0 clean, 1 on a
+fatal finding (or any finding under `--strict`), 2 on usage; `--json` emits the
+whole batch as one document, and `--quiet` prints the findings alone, so a
+clean mod prints nothing and the exit code is the answer. The rule ladder is
+`MK400`-`MK410` and is listed in `tools/modkit.py`'s section header.
+
+Then the headless harness, which takes the generation without booting Gold:
+
+```lua
+local run = T.sdk.loadMod("mods/my_mod", { generation = 2 })
+T.eq(run.mod and run.mod.state, "loaded",
+  "runs on gen 2: " .. tostring(run.mod and run.mod.skipReason))
+T.eq(#run.errors, 0, "and loads with no boot errors")
+```
+
+Everything else is the production path: same loader, same validate, same
+topological sort, same merge. Assert the state as well as the error count: a
+gate skip is deliberately not an error, so `#run.errors == 0` passes for a mod
+that never ran a line.
+
+Neither substitutes for a real Gold boot, and the two output channels there are
+not the same. The adapter's own warnings (`Gen2Compat.warnOnce`) go to the log
+only, each attributed to the mod holding the facade. The boot error feed the
+manager shows is `loader.errors`: a failed mod, a duplicate id, a registry with
+no Gen 2 target, a cross-validation problem, and a require for a Gen 1 module
+the adapter does not serve. A skipped mod and a degraded member are on neither
+list, by design.

+# RFC 0008 — Runtime mod option schema export
+
+## Status
+
+Proposed. Engine: `src/mods/Loader.lua`. Tests:
+`tests/mod_loader_tests.lua`. This RFC defines an optional filesystem
+contract; it does not require a native launcher or any other consumer.
+
+## Motivation
+
+A native launcher may want to present settings for installed mods before it
+starts the game. Running every mod's entry chunk in that launcher just to
+discover its settings would duplicate engine behavior and give the launcher
+an unnecessary code-execution surface. The engine already has the authoritative
+runtime schemas after mod loading, so it can publish a data-only snapshot for
+platform shells that want one.
+
+## The exact contract
+
+After the mod loader has finished running entry chunks, it may write
+`mod_option_schemas.json` beside `options.lua` in the same filesystem. The
+document is a snapshot of the current boot; it is not a second settings store
+and does not change how option values are read or written.
+
+Version 1 has this shape:
+
+```json
+{
+  "schema_version": 1,
+  "mods": {
+    "example": [
+      {"key":"enabled","type":"toggle","label":"Enabled","default":true},
+      {"key":"mode","type":"choice","label":"Mode","default":"safe",
+       "choices":[["Safe","safe"],["Fast","fast"]]},
+      {"key":"rate","type":"number","label":"Rate","default":5,
+       "min":0,"max":10,"step":1},
+      {"key":"name","type":"text","label":"Name","default":"","maxLen":12}
+    ]
+  }
+}
+```
+
+`mods` is keyed by mod id. Its rows come from the runtime
+`mod.options:define` schema, or from the legacy manifest `options_schema` file
+when the runtime schema is absent. The supported row types are `toggle`,
+`choice`, `number`, and `text`. Their optional fields retain the meanings
+established by the existing in-game option UI: choices are `[label, value]`
+pairs, numeric rows may provide `min`, `max`, and `step`, and text rows may
+provide `maxLen`. A row may also use
+`visible_if = {key = "mode", equals = "compact"}` or replace `equals` with
+`not_equals`. This only hides the in-game menu row; the schema and stored value
+remain available, and consumers that do not implement conditions may ignore
+the field.
+
+Only mods that are enabled and successfully loaded in the current boot are
+included. A disabled or failed mod must not contribute rows. If an older
+snapshot exists and the current boot has no schema-bearing mods, the producer
+overwrites it with `{"schema_version":1,"mods":{}}`; this prevents stale
+settings rows from surviving a disable or load failure. A fresh mod-free boot
+does not create the file, and a filesystem without write support is tolerated.
+
+The producer writes the snapshot after entry chunks and the final load set
+have been established. Consumers must treat the file as untrusted input and
+must not execute anything from it.
+
+## Compatibility and versioning
+
+The contract is optional on both sides. A native consumer may be absent, and
+the engine continues normally if the file cannot be written. A native
+consumer is not required to render, validate, or persist every supported row;
+it may ignore an unknown row type or optional field.
+
+For compatibility with files produced by the original unversioned prototype,
+a missing `schema_version` means version 1. Consumers must ignore documents
+with a newer version rather than guessing at their shape. Producers must bump
+the version whenever they change the document envelope or the meaning of an
+existing field. New optional row fields that older consumers can safely ignore
+do not require a bump. Version 1 is therefore the legacy unversioned format as
+well as the explicitly versioned format shown above.
+
+## Migration note
+
+Nothing. Existing mods, option values, and the in-game options UI are
+unchanged. Platforms that do not consume `mod_option_schemas.json` have no
+new integration requirement.
+
+## Parity tests
+
+`tests/mod_loader_tests.lua` verifies the explicit version, runtime and legacy
+row round-tripping, enabled/disabled filtering, failed-mod filtering,
+stale-snapshot clearing, and tolerance of a read-only filesystem.
+
+## Deprecation etiquette
+
+Nothing is deprecated. The unversioned file form remains readable as legacy
+version 1; new producers write the explicit `schema_version` field.
