-# KANTO-CONTINUE: executing the never-run half of Gold (sections 19-32)
-
-Deferred from the 2026-08-09 fix campaign by request. This doc is self-contained: the
-audit documents it was distilled from are being retired, so everything a future session
-needs is here.
-
-## What this is
-
-The Johto main line (walkthrough sections 00-18) is proven: the route bot beats Champion
-Lance with every row passing. Kanto (sections 19-32) is extracted and wired but has
-NEVER been executed by any bot row, driver, or human. Every entry below reads clean in
-static review (cache + code + cart source were cross-checked adversarially); the risk is
-purely runtime. The job: make each beat actually run, fix what breaks, and leave
-executable evidence (bot rows or assertion drivers) behind.
-
-## State after the 2026-08-09 campaign (what changed under you)
-
-- ~80 defects fixed across the port; 91/91 gen2 suites, engine 128/128, T3 all green.
-- The post-game handoff WORKS now: post-E4 credits end at the title screen, and
-  CONTINUE consumes the post-game spawn (HallOfFame.consumePostGameSpawn): after Lance
-  you continue in NEW_BARK_TOWN, after Red at SILVER_CAVE_OUTSIDE (23,20). Section 19
-  is reachable by normal play for the first time.
-- The Snorlax wake chain is fully functional (engine-flag bridge unlocks the Pokegear
-  and EXPN card; the tuned radio song persists after closing the gear; SnorlaxAwake
-  fires; proven live by tests/drivers/gold_radio_persist.lua).
-- Landed systems Kanto beats depend on: phone random/outgoing calls, field item use
-  (Escape Rope/Dig via save.backupWarp), Repel, swarms, Rock Smash encounters,
-  waterfall current tiles, roamer scatter on CONTINUE, trap volatiles + FORCESHINY
-  battle types (beast catching in section 32 is now mechanically possible), badge
-  boosts, held items, specialty balls (Lure Ball needs battleType 'fish', already
-  stamped by updateFishing).
-- NPC HOUR WINDOWS are now enforced (they were not when the Johto route was authored).
-  Any Kanto row that talks to a time-gated NPC must pin the clock (POKEPORT_GOLD_HOUR /
-  POKEPORT_GOLD_DAY) or handle absence. Only 11 hour-gated objects exist on the whole
-  cart: CELADON_GAME_CORNER 6/7, GOLDENROD_GAME_CORNER 4/5, MOUNT_MOON_GIFT_SHOP 1-4,
-  and the three Moms in PLAYERS_HOUSE_1F; Celadon and Mt Moon are the Kanto exposures.
-- The game clock now anchors on every new game (cart InitClock semantics), so time of
-  day no longer follows the host wall clock in driver runs; POKEPORT_GOLD_HOUR pins
-  the anchored base too. Runs are reproducible across day/night; a pre-existing flake
-  class (night runs catching HOOTHOOT where day runs catch PIDGEY, shifting grind
-  levels) died with it.
-- Battles hit harder both ways since the cart MIN_DAMAGE floor landed; grind budgets
-  tuned for the old numbers may need a nudge.
-
-## Known bot weaknesses to expect (verified pre-existing, not campaign regressions)
-
-- Pathfinding pocket: travel into ILEX_FOREST / SLOWPOKE_WELL bounces (probe
-  CHERRYGROVE_CITY>ILEX_FOREST reports no route), and route row 16.54 gives up the
-  walk to VICTORY_ROAD_GATE with the identical TELEPORT signature in every logged run.
-  Kanto routing should waypoint doors explicitly per the ops recipes above.
-- Optional buy rows 04.5d and 18.g4/18.g5 fail whenever the wallet is empty at that
-  point in the run; they are budgeting gaps in the route, not engine bugs.
-- Grind row 08.g (Route 41 water) has almost no margin; with the clock now anchored
-  its inputs are stable, but a low-level POLIWAG catch can still stretch it.
-
-## How to run things
-
-Identity/cache: gold-dev (~/Library/Application Support/LOVE/gold-dev/gold), rebuilt
-2026-08-09 with swarm/rock/roam tables. Checkpoints gold-ckpt-NN.lua exist per section;
-gold-ckpt-18-pristine.lua is the post-E4 seed. ROM: ../decprep/Pokemon - Gold
-Version.gbc. Cart source: ../pokegold (cite it in any hand-ported code).
-
-Headless love needs a pty on macOS; wrap every run:
-  perl -e 'alarm 900; exec @ARGV' python3 -c "import pty; pty.spawn(['love','.'])"
-
-Full bot run:  POKEPORT_IDENTITY=<id> POKEPORT_GAME=gold POKEPORT_SPEED=200 \
-  POKEPORT_GOLD_CKPT=1 POKEPORT_GOLD_STALL=20000 POKEPORT_GOLD_LOG=/tmp/b.log \
-  POKEPORT_DRIVER=tests/drivers/gold_bot.lua love .
-Resume a section: POKEPORT_GOLD_RESUME=NN (same identity, prior CKPT=1 run).
-Travel probe: POKEPORT_GOLD_PROBE="MAP_A>MAP_B" with tests/drivers/gold_travel_probe.lua.
-Map graph: luajit tools/goldwalk/mapgraph.lua path|map|reach|audit; regenerate
-tests/drivers/gold/map_regions.lua with `mapgraph.lua graph >` after ANY extractor map
-change, then re-check route region indices.
-Route validation (before any run): luajit tests/gold_route_validate_test.lua and
-luajit tests/gold_flag_names_test.lua.
-Suites: GOLD_CACHE="$HOME/Library/Application Support/LOVE/gold-dev/gold" luajit
-tests/gen2_<name>_test.lua; tiers run_engine/run_modkit/run_tests.
-Reimport after extractor/manifest changes: python3 tools/make_gold_manifest.py, then
-POKEPORT_IMPORT_TRACE=1 POKEPORT_IDENTITY=gold-dev POKEPORT_IMPORT_ROM="../decprep/\
-Pokemon - Gold Version.gbc" POKEPORT_IMPORT_ONLY=1 POKEPORT_FORCE_IMPORT=1 \
-POKEPORT_GAME=gold love .
-
-## Recommended shape of the work
-
-1. Extend tests/drivers/gold/route.lua with sections 19-32 (the row format, ops and
-   evidence rules are documented in the file head and bot.lua). Seed runs from
-   gold-ckpt-18-pristine plus the now-working post-credits CONTINUE. `expect` flags are
-   the only oracles; never make a row load-bearing on a soft-failing map.
-2. Highest-risk multi-map scripted chains first: S.S. Aqua voyage, Machine Part chain,
-   PASS/Magnet Train chain. Each deserves an assertion driver even if bot rows also
-   cover it.
-3. Time-gated beats (S.S. Aqua sailing days, Indigo rival Mon/Wed, Dragon's Den
-   Tue/Thu, Clefairy Monday night, TM03 night gate) need POKEPORT_GOLD_DAY/HOUR pins.
-4. Johto stragglers are folded in below (lighthouse descent, TM08 flake, and the
-   optional gift beats); they ride the same route-extension pass.
-5. Section 32 (beasts) last: it needs long roaming play; trap volatiles and FORCESHINY
-   landed this campaign, so Mean Look + Heavy/Fast Ball plans are now viable.
-
-## Also deferred (deliberate stubs, do not re-flag)
-
-Time Capsule trading, Trainer House CAL2/Mystery Gift visitor, Silver-version import,
-Cable Club link rooms, and Game Boy Printer output are deliberate product-level stubs,
-not campaign work.
-
-## The beats, in walkthrough order
-
-### Runtime coverage ends at the Hall of Fame: no bot row, driver, or human has run any Kanto beat (sections 19-32) or the section 14 Tin Tower/Whirl Islands content
-
-walkthrough section(s) 19,20,21,22,23,24,27,28,29,30,31,14 | missing
-
-One root cause: tests/drivers/gold/route.lua (1264 lines) ends at row 18.20 (settle HALL_OF_FAME, expect EVENT_BEAT_ELITE_FOUR); the campaign covers asm-walk sections 00-18 only and none of the 24/36 gold_* drivers reaches any Kanto map, so sections 19-32 have zero execution proof. Extend route.lua into sections 19-32 and/or add targeted drivers. Per section pair: (s19/20) next rows are the Elm ticket (needs the post-credits spawn fix or a fly detour from Indigo), the ship crossing as far as the docking events, the Surge fight, and a Saffron Gym pad-chain assertion. (s21/22) All 24 route/gym trainers resolve in cache with correct parties: Route 9 six (Edna, Sid, Dean, Sidney, Tim, Heidi); Route 25 seven plus Kevin, whose Nugget-then-battle script 50:488d is hand-shaped (a full bag aborts before the battle, cart behavior); Cerulean's three swimmers; Route 10 South's Jim and Robert (Robert's Quagsire holds a BERRY via TRAINERTYPE_ITEM); Route 8's five; Celadon Gym's five including the twins' shared beat flag. Sight-line engagement is Trainers.sees (proven by the Johto bot); prize money base x level x 4 is Prize.lua; Erika's class item extracts as HYPER_POTION (the walkthrough's 'three Full Restores' is a FAQ error, not a port gap); Gold-only wilds (Mankey line Route 9, Growlithe Routes 7/8) come from the ROM version branch; Route 8's PRZCureBerry fruit tree is a fruittree op (Vm.lua:1218) into Apricorns.lua daily reset. One Kanto smoke-run converts the whole block. (s23/24) Nothing touches Routes 11-19, Fuchsia City/gym, Vermilion Snorlax, Diglett's Cave, Route 2, Pewter; the report's three blocker findings (START menu row, Pokegear card flags, radio persistence) are exactly the UI-plumbing breaks data audits miss: a gold_snorlax_wake.lua that grants the gear and EXPN card the way the game does (setflag 4, setflag 0, setflag 3 through the VM, not by poking save fields), tunes the radio, closes the gear, and talks to the Snorlax would currently fail at three separate steps; gold_cycling_road.lua and gold_fuchsia_gym.lua are the other two cheap proofs (gold_menu_shots.lua:72-73 only ever hand-seeded save fields). (s27/28) Drive first: (1) Cinnabar Blue talk -> disappear -> clearevent 1910 -> Viridian Gym populated -> Blue beaten -> ENGINE_EARTHBADGE set -> VAR_BADGES answers 16 (a break anywhere makes the 16th badge unobtainable and the Mt. Silver gate unpassable); cache chain exists: CINNABAR_ISLAND obj 1 SPRITE_BLUE at (9,6) scriptKey 4e:4985 eventFlag 1909; VIRIDIAN_GYM objs 1-2 gated on 1910; (2) the ROUTE_20 MAPCALLBACK_NEWMAP 4e:4cfa setevent 215 / ROUTE_19 MAPCALLBACK_TILES 4e:4f09 changeblock unseal pair (regression walls off Route 19). Driver: surf Pallet -> Route 21 -> Cinnabar -> talk to Blue -> Route 20 -> beat Blaine -> fly to Viridian -> beat Blue. (s29/30) No rows for Kanto OAKS_LAB, ROUTE_22, ROUTE_28, SILVER_CAVE_OUTSIDE, or the Union Cave B2F Lapras revisit (route.lua's only Union Cave rows are 03.29/04.g); risk concentrates on composites never run together: the 16-badge Oak visit with ProfOaksPCBoot text chain, the double Cut approach to the Route 28 west strip, surf-to-talk on the drifting SWIM_WANDER Lapras (Lake of Rage Gyarados proves the shape via gold_lake_probe.lua), and the daily-flag consume-and-respawn cycle across a save reload; a targeted gold_lapras_probe driver (clockDay=5, walk in, assert object present, catch, walk out, re-enter, assert gone) plus route extension converts inspected to proven. (s31) All six Silver Cave maps decode (warps, item balls flags 1689-1693, hidden items, SILVER_CAVE_OUTSIDE flypoint callback, PALETTE_DARK on Room 1, grass/water tables including Room 2 water); Flash lifts PALETTE_DARK via Palettes.isDarkness + World flashUsed; Surf/Waterfall live in FieldMoves with the badge table; gen2 ledges landed via Permissions.ledgeFacings / World:tryLedgeJump (the asm-walk's 'ledge hop missing' row is stale, GOLD-NEXT-RUN records the fix); the flypoint is FieldMoves.lua:386 flag 75; but no driver has entered Silver Cave, used Waterfall on Room 2's two bands, hopped Room 1's Escape Rope ledge, or talked to Red (closest: gold_halloffame_shots, gold_hm07_probe which proved Waterfall only at Tohjo Falls). (s14) The bot covers sections 10,11,12,13,16,17,18 and never section 14 (Ho-Oh is optional); untested: the 4F-9F ladder/hop mazes (depend on the recently added ledge-hop and one-way-wall support), the Ecruteak entrance sage scene retarget from Morty's setmapscene, the 1F sage unmasking off EVENT_TEAM_ROCKET_DISBANDED (set on the Gold arm of the Radio Tower boss script), the roof save/reset loop, and the entire Gold-side Whirl Islands dive; needs one probe driver carrying a RAINBOW_WING save up the tower and one diving to the Lugia chamber.
-
-*How to prove it:* Extend tests/drivers/gold/route.lua past row 18.20 into sections 19-32, and/or write the named targeted drivers: gold_snorlax_wake.lua, gold_cycling_road.lua, gold_fuchsia_gym.lua, a gold_lapras_probe (clockDay=5 present/absent cycle), a Cinnabar-to-Viridian 16th-badge driver, a Route 20/19 unseal driver, a Silver Cave/Red driver, a Tin Tower RAINBOW_WING probe, and a Whirl Islands Lugia dive probe.
-
-*Notes:* Merged from the parent heading plus six 'Also filed as' sub-findings (all one cause). Doc's own ratings: parent missing/minor (s19,20, already in ledger); s21,22 unverified/minor; s23,24 unverified/minor; s27,28 missing/major; s29,30 unverified/minor; s31 unverified/minor; s14 unverified/minor. The adversarial re-check ran on the s27/28 sub-claim, tried to refute and could not; its one correction: tests/drivers/gold/flag_names.lua and map_regions.lua DO name the Kanto maps (map_regions even carries CINNABAR/SEAFOAM/VIRIDIAN region graphs, so bot travel there is data-ready) but they are lookup tables, not executed coverage. 'Implemented statically, executed by nobody' matches the project's Roamers/Events:restore failure mode. GOLD-WALK-HANDOFF sections 1 and 4 already document the Johto-only scope.

Port sprite toggles for the post-Hall-of-Fame sailor (events 1847/1848) are armed by the HOF script. All data extracted, every op has a proven Johto call site; matched op-for-op against pokegold maps/OlivinePort.asm. Needs one live run or driver.
-

Statically verified: cache holds full bytecode for PowerPlantManager 54:4dbd with both branches (54:4deb takeitem MACHINE_PART / 54:4e04 TM give guarded by event 223), gym scene script 54:4332 sdefer 54:4336 with all 34 rows, Route 24 grunt script 50:4407; initial_events.lua seeds flags 251/1900/1901/1902/1903/1906/1907 at new game exactly as InitializeEventsScript does (pokegold engine/events/std_scripts.asm:546-550); World.lua:607 applies the seed while EVENT_INITIALIZED_EVENTS is clear.

-walkthrough section(s) 21 | unverified
-
-The date cutscene at Route 25 cells (42,6)/(42,7) is what clears EVENT_TRAINERS_IN_CERULEAN_GYM 1903 and populates the gym with Misty, three swimmers, and the guide; without it Misty never appears and the Cascade Badge is unreachable. Cache has both coord events with sceneId=1 (scripts 18305/18369) and full scripts 50:4781/50:47c1 (34-row cutscene: heart emote, boyfriend flees, Misty approach movement, clearevent 1903, setscene 0, special 60=RestartMapMusic), armed by gym grunt script 54:4336 row 27 (setmapscene group=7 map=16 scene=1). Engine deps: World:tryCoordScript (World.lua:5006) filters on the map scene id; mapScenes persist on the save (GOLD-INDEX tier note on World:loadPlayerData). CeruleanGymMistyScript 54:438a is in the cache; MISTY trainer 1 party (L42 Golduck, L42 Quagsire, L44 Lapras, L47 Starmie with full movesets) extracts correctly; baseMoney 25 so the 4700G payout follows from Prize.reward.
-
-*How to prove it:* Driver: arm the scene via the gym grunt, trigger the date coord event at (42,6)/(42,7), assert 1903 cleared and the gym populated, then fight Misty and assert the Cascade Badge and 4700G.
-
-*Notes:* Doc rating: unverified/blocker, new. Correction embedded in the doc: Misty gives NO TM on the Gold cart, only the badge plus retroactive swimmer beat flags; the walkthrough and the lead's 'TM from Misty' are wrong about the cart, nothing is missing in the port there.

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

-For a Gold cart, Lugia needs the SILVER_WING carried in the bag (WhirlIslandLugiaChamberLugiaCallback does checkevent EVENT_FOUGHT_LUGIA then checkitem SILVER_WING), and in Gold the wing comes from the Pewter City gramps (pokegold maps/PewterCity.asm PewterCityGrampsScript: checkver, Silver arm branches away, Gold falls through to verbosegiveitem SILVER_WING + setevent). Verified in cache: PEWTER_CITY object 3 (SPRITE_GRAMPS at 29,17) scriptKey 4d:583e = faceplayer / opentext / checkver / iftrue 4d:585c / checkevent 121 / verbosegiveitem item 71 / setevent 121 / closetext / end, all generic opcodes. The Lugia chamber map, its SPRITE_LUGIA object (scriptKey 47:41a0, eventFlag 1853), and its MAPCALLBACK_OBJECTS callback (47:418c) are in the cache using only implemented machinery. Route bot has no section 14/25 rows (grep 'id = "1[0-9]' shows 10,11,12,13,16,17,18). One mechanical gap on the dive path: the waterfall forced-down item, reported separately in the doc.
-
-*How to prove it:* Driver or bot rows: reach Pewter in Gold, talk to the gramps (assert SILVER_WING item 71 given, event 121 set), then the full Whirl Islands dive to the Lugia chamber.
-
-*Notes:* Doc rating: unverified/major, new. The waterfall forced-down item on the dive path is a separate finding elsewhere in the doc, not part of this entry.

ENGINE_FLYPOINT_VERMILION comes from MAPCALLBACK_NEWMAP on both VERMILION_PORT and VERMILION_CITY (setflag 57); the port's fly table carries the matching row (FieldMoves.lua:392) and World:runMapCallback has a live call site (World.lua:5659 plus the MAPCALLBACK_OBJECTS call in setMap). Fly deliberately stays region-locked exactly like the cart (FieldMoves.flyPoints, FieldMoves.lua:442: Kanto page only after SPAWN_INDIGO, no cross-region fly, verified against pokegold engine/pokegear/pokegear.asm .KantoFlyMap). Kanto music extracted: audio.lua songs has 92 entries, musicOrder includes Music_VermilionCity and Music_ViridianCity (musicOrder[63]=Music_VermilionCity), mapSongs carries all 362 map rows.
-
-*How to prove it:* Driver: dock at Vermilion, assert flags 1841/1840/1849/48 set and 1843 cleared, flypoint flag 57 set on map entry, and Vermilion/Viridian city music playing.

Parties in trainers.lua match data/trainers/parties.asm exactly: Surge is RAICHU44/ELECTRODE40/MAGNETON40/ELECTRODE40/ELECTABUZZ46 with full TRAINERTYPE_MOVES movesets; Vincent, Horton, Gregory all match (GUITARIST 2/JUGGLER 3/GENTLEMAN 3). Trainer AI item use implemented: Ai.ITEM_ORDER/Ai.chooseItem (Ai.lua:1368-1400) dispatched from Battle.lua:1790 (AI_SwitchOrTryItem) off the extracted class attributes. The gym has no puzzle in Gen 2, matching the walkthrough's power-outage line.

The Route 6 Saffron gate guard at (0,4) stands off the walking lane and is dialogue only (branches on EVENT_RETURNED_MACHINE_PART). ROUTE_6 grass and water encounter tables (Abra/Magnemite slots) are present in encounters.lua. Nothing gated on engine work; it has just never been walked.

-The gym's whole puzzle is 30 warp pads (cache SAFFRON_GYM warps 3-32) that all target SAFFRON_GYM itself; the only route to Sabrina is entrance pad (11,15) -> ... -> (1,5) -> (11,9). The engine mechanism exists and reads correct: pads are COLL_WARP_PANEL 0x7c, an immediate warp (Permissions.lua:311); World:takeWarp (World.lua:6022-6040) handles a destination equal to the current map through setMap; warpCooldown keyed on the landing cell (World.lua:6135 set, 6217-6222, 6240 suppression check) stops the landing pad from re-firing until the player steps off, exactly what a pad-to-pad maze needs. But the asm-walk's own port-coverage table flags that no driver has ever exercised a same-map warp chain, and no Kanto run exists. If this breaks, Sabrina is unreachable and the 10th badge (and eventually Red's gate) is lost.

Leftovers: CeladonCafeTrashcan bg event at (7,1) key 5e:648c present, plain giveitem bytecode with the flag only set on success so a full pack retries, exactly the cart. Hidden PP Up at Celadon (37,21): BGEVENT_ITEM row present, handled by HiddenItems (fixed PP_UP; the walkthrough's 'random PP Up' is wrong on the cart too).

Both callbacks extracted (type 5 NEWMAP 5b:6763 re-hides the stone on entry; type 2 OBJECTS 5b:6767 hides the rock). The rock object (SPRITE_ROCK at 7,7, scriptKey 5b:67ee = jumpstd SmashRockScript) resolves to the real SmashRock/AskRockSmash bodies GOLD-INDEX.md:377-382 documents; follow/stopfollow are implemented (Vm.lua:1009,1026). Flag semantics match the cart: ENGINE_MT_MOON_SQUARE_CLEFAIRY lives in wDailyFlags2 (pokegold constants/engine_flags.asm:105-106) and the port clears id 87 in Apricorns.DAILY_ENGINE_FLAGS, so the dance is once per day, i.e. once per Monday night. Unproven in-game: (a) whether the appeared rock correctly blocks/receives the A press on the Moon Stone tile at (7,7) and Rock Smash then exposes the hidden item in the same visit, and (b) the full follow-chain animation. The stubbed RockMonEncounter (CallAsm STUB_ROWS) does NOT affect this rock: MOUNT_MOON_SQUARE is not in the cart's RockMonMaps (pokegold data/wild/treemon_maps.asm:43-48), so no encounter roll is owed here.

The daily rematch flag ENGINE_INDIGO_PLATEAU_RIVAL_FIGHT (id 92) is in Apricorns.DAILY_ENGINE_FLAGS so it clears on the daily rollover. The rematch parties RIVAL2 members 4-6 (L45-50 with CROBAT) are in trainers.lua. Nothing looks missing, but the coord-event choreography in the Pokecenter (rival walks in as you leave) is the kind of scene worth a driver before trusting; filed unverified rather than implemented for that reason.
-
-*How to prove it:* Driver: set EVENT_BEAT_RIVAL_IN_MT_MOON via the Mt Moon fight, force weekday Monday/Wednesday, enter the Indigo lobby and assert the rematch triggers; force Tuesday/Thursday and assert the Dragon's Den object 4 state.
-
-*Notes:* Doc rating: unverified/minor, new. Merge-with hint: overlaps indigo-lobby-rival-rematch (s18), the same Indigo Plateau rematch filed from the section-18 audit; that filing cites World:weekday at World.lua:1247 and scriptKeys 5a:48ff/5a:4940.

-### Indigo lobby rival rematch (Monday/Wednesday, RIVAL2, post Mt. Moon) armed on tiles the walkthrough crosses, never run
-
-walkthrough section(s) 18 | unverified
-
-Not in the walkthrough text but armed on the lobby tiles it crosses: coord events at (16,4)/(17,4) run PlateauRivalBattle1/2 (cache scriptKeys 5a:48ff/5a:4940), which fight the RIVAL2 second-tier party when EVENT_BEAT_RIVAL_IN_MT_MOON is set, ENGINE_INDIGO_PLATEAU_RIVAL_FIGHT is clear, and VAR_WEEKDAY is Monday or Wednesday (pokegold maps/IndigoPlateauPokecenter1F.asm). Every dependency exists: coord events and scripts extracted, VAR_WEEKDAY answers the real weekday (World:weekday, World.lua:1247), the daily engine flag is registered for midnight reset (Apricorns.lua:88, id 92 ENGINE_INDIGO_PLATEAU_RIVAL_FIGHT), and RIVAL2 parties 4-6 (SNEASEL/45, CROBAT/48, MAGNETON/45, GENGAR/46, ALAKAZAM/46, starter/50) are in the trainers cache. But the gate flag EVENT_BEAT_RIVAL_IN_MT_MOON is Kanto content no run has ever set.
-
-*How to prove it:* Should be picked up when section 26 is audited/run: same driver as rival-rematch-mtmoon, entering the lobby on Monday/Wednesday with the Mt Moon flag set and asserting the coord-event battle fires.
-
-*Notes:* Doc rating: unverified/minor, new. Merge-with hint: same beat as rival-rematch-mtmoon (s26); kept separate because the doc filed both headings. Line-cite difference between filings: World.lua:1247 (weekday) here vs World.lua:1289 (readVar VAR_WEEKDAY) there.

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

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

-
-### New Bark rival push scene (talk to rival by the lab) unproven; low risk, zero coverage
-
-walkthrough section(s) 00 | unverified
-
-Walkthrough: 'If you talk to him, he'll push you out of the way.' NewBarkTownRivalScript is optional, repeatable (sets no flag) and uses follow PLAYER, applymovement with turn_head/step/fix_facing/jump_step, and SFX_TACKLE. Every opcode involved is implemented (follow/stopfollow in the VM, jump_step in Movement.lua which the ledge fixes exercised), and the sibling teacher-drag scene has a dedicated driver (tests/drivers/gold_teacher_scene.lua), but no driver or test touches this specific scene and the route bot never talks to optional NPCs. Cache maps.lua NEW_BARK_TOWN objects include the rival with a scriptKey and eventFlag.
-
-*How to prove it:* A short driver that talks to the rival by the lab and observes the push movement chain, mirroring gold_teacher_scene.lua.
-
-*Notes:* Doc rating: unverified/minor, new.
-
-
-### Kiyo battle and Tyrogue gift (Mount Mortar B1F): fully wired, never exercised by any driver or bot run
-
-walkthrough section(s) 15 | unverified
-
-The game's only Tyrogue. Cache scripts['46:5eec'] holds all 29 rows of MountMortarB1FKiyoScript (checkevent 97 / 1193, winlosstext, loadtrainer class BLACKBELT_T member 6, startbattle, reloadmapafterbattle, setevent 1193, readvar var=1 VAR_PARTYCOUNT, ifequal 6, givepoke species 236 level 10, setevent 97); trainers cache has BLACKBELT_T[6] KIYO = L34 HITMONLEE + L34 HITMONCHAN (KIYO object at 13,4 with scriptKey 46:5eec); readvar VAR_PARTYCOUNT is a real read (World.lua:1271); givepoke is implemented at Vm.lua:443. The full dependency chain has never run: Surf across the 1F Outside lake, the in-cave Waterfall climb to warp 4 at (17,5), the 2F/1F-inside/B1F warp descent, the battle, and the gift. The waterfall climb mechanic itself is bot-verified only at Tohjo Falls; route.lua contains no MORTAR/KIYO/DARK_CAVE rows.
-
-*How to prove it:* A Mount Mortar driver: Surf the outside lake, Waterfall to warp 4 (17,5), descend to B1F, beat Kiyo, assert Tyrogue (species 236, L10) given with a party of <6 and events 97/1193 set.
-
-*Notes:* Doc rating: unverified/major, new. Correction embedded: GOLD-INDEX's claim that only VAR_WEEKDAY and VAR_FACING answer readvar is STALE; World.lua:1265-1330 now answers essentially every VAR_*.
-
-
-### Blackglasses pharmacist in Dark Cave Blackthorn entrance extracted exactly, never run (same for TM13 Snore and Revive balls)
-
-walkthrough section(s) 15 | unverified
-
-The script is fully extracted (cache scripts['47:436c'], 13 rows matching pokegold maps/DarkCaveBlackthornEntrance.asm exactly: checkevent / verbosegiveitem / iffalse pack-full arm / setevent), the spinning NPC object (SPRITE_PHARMACIST) is in the cache at (7,3) with that scriptKey, and verbosegiveitem is implemented in the VM. Reaching him also needs Flash plus Surf inside the cave, both implemented. The same unverified state covers the TM13 Snore and Revive item balls beside him (item ball arm is implemented and tested). No driver enters Dark Cave and the bot route bypasses it (grep DARK_CAVE in route.lua is empty).
-
-*How to prove it:* A Dark Cave driver: Flash + Surf to the Blackthorn entrance, talk to the pharmacist (assert Blackglasses given), pick up TM13 Snore and the Revives.
-
-*Notes:* Doc rating: unverified/minor, new.

-### Master Ball from Elm after eighth badge: route rows exist but optional, no run log confirms the event ever set
-
-walkthrough section(s) 16 | unverified
-
-ProfElmScript's ElmCheckMasterBall gate is checkflag ENGINE_RISINGBADGE then verbosegiveitem MASTER_BALL then setevent EVENT_GOT_MASTER_BALL_FROM_ELM (pokegold maps/ElmsLab.asm:57-61). All generic extracted bytecode; checkflag over ENGINE_* badges works since the badge-store fix (GOLD-WALK-HANDOFF.md:502, badges routed into save.player.badges). The route bot has rows 16.24/16.24b for this beat but both are marked optional = true, and no run log or handoff note confirms EVENT_GOT_MASTER_BALL_FROM_ELM was ever actually set in a live run (no MASTER hits in GOLD-NEXT-RUN.md run logs). A full bag silently skips the setevent (verbosegiveitem iffalse), same as the cart.
-
-*How to prove it:* Make route rows 16.24/16.24b non-optional (or run them) and assert EVENT_GOT_MASTER_BALL_FROM_ELM set with bag space available.
-
-*Notes:* Doc rating: unverified/major, new.
-
-
-### Everstone from Elm by showing a self-hatched Togepi: pieces individually proven, full chain never exercised end to end
-
-walkthrough section(s) 16 | unverified
-
-The gating special FindPartyMonThatSpeciesYourTrainerID is a real handler with the own-OT check (Specials.lua:1134), and the phone-call prerequisite is NOT required: pokegold maps/ElmsLab.asm ElmCheckTogepiEgg -> EVENT_TOGEPI_HATCHED -> ElmEggHatchedScript re-runs the same species scan, so a hatched Togepi in the party is sufficient (maps/ElmsLab.asm:62-95, engine/phone/scripts/elm.asm:46). Egg hatching has a driver (tests/drivers/gold_egg_hatch.lua) and PC withdraw exists (BoxMenu.lua / PcMenu.lua). The full chain (hatch with your OT, withdraw, talk, EVENT_SHOWED_TOGEPI_TO_ELM, verbosegiveitem EVERSTONE) has never run end to end. The .egghatched arm of ElmPhoneCalleeScript (sets EVENT_TOLD_ELM_ABOUT_TOGEPI_OVER_THE_PHONE) lives in the bank $41 callee scripts and only matters for the alternate entry path. No route row exists for the Everstone.
-
-*How to prove it:* A driver chaining gold_egg_hatch-style hatching (own OT), PC withdraw, and the Elm talk, asserting EVENT_SHOWED_TOGEPI_TO_ELM and EVERSTONE in bag.
-
-*Notes:* Doc rating: unverified/minor, new.

-### TM37 Sandstorm happiness gate at the Route 27 house never exercised; gate is first-slot happiness >= 150
-
-walkthrough section(s) 16 | unverified
-
-The granny's script is extracted (cache scripts['60:6352'], 9 rows: checkevent, special id 88, ifgreater, sjump into the loyal/disloyal arms) and special id 88 resolves through constants.specialOrder with the VM's order[id+1] rule (Vm.lua:1773) to specialOrder[89] = GetFirstPokemonHappiness, a real handler at Specials.lua:1506 reading the first non-egg party member. The cart gate is happiness >= 150 on the FIRST party slot (ifgreater 150-1), not 'one of your Pokemon'. Happiness accrues via Happiness.lua stepped from StepEvents. No driver or bot row enters ROUTE_27_SANDSTORM_HOUSE.
-
-*How to prove it:* Driver: enter ROUTE_27_SANDSTORM_HOUSE with a first-slot mon at happiness >= 150 and assert TM37 given; also assert the disloyal arm below 150.
-
-*Notes:* Doc rating: unverified/minor, new.

-
-### Route 27 whirlpool island (Bird Keeper Jose, TM22 Solarbeam, Rare Candy) and Tohjo Falls Moon Stone never run; whirlpool mechanic only proven on Route 41
-
-walkthrough section(s) 16 | unverified
-
-The whirlpool mechanic is implemented and driver-verified, but on Route 41, not here: tests/drivers/gold_water_moves.lua:105-124 clears a real whirlpool block with GLACIERBADGE gating and asserts the block replacement. The Route 27 island content is all in the cache (TM_SOLARBEAM ball at (60,12) item id 213 with event flag, Rare Candy ball at (53,12), BIRD_KEEPER[14] JOSE = L35 FARFETCH_D with phone contact rows; maps.ROUTE_27 objects rows 6-8) and the item ball arm is implemented, but the bot route crosses Route 27 only via Tohjo Falls and never surfs south past Gilbert (route rows 16.42-16.43 skip the south water), so this specific whirlpool, the Jose fight, and the TM22 pickup have never run. Same for the Tohjo Falls MOON_STONE ball at (2,6) (maps.TOHJO_FALLS object 1), which the walkthrough itself never mentions.
-
-*How to prove it:* Driver or route rows: surf south past Gilbert, clear the Route 27 whirlpool, fight Jose, collect TM22 and the Rare Candy; separately pick up the Tohjo Falls Moon Stone.
-
-*Notes:* Doc rating: unverified/minor, new.
-
-
-### Route 26 heal house free heal extracted with all specials real, never entered
-
-walkthrough section(s) 16 | unverified
-
-The teacher's script is extracted (cache scripts['60:60e6'], 17 rows) and every special id in it resolves via order[id+1] to a real handler: 47 FadeOutToBlack, 50 ReloadSpritesNoPalettes, 27 HealParty, 49 FadeInFromBlack, 60 RestartMapMusic (Specials.lua:450, :999, :1025, and the fade-in/restart pair at :1059). Unconditional and repeatable like the cart. No driver or bot row ever enters ROUTE_26_HEAL_HOUSE; the bot route's Route 26 leg is a single travel row straight to the gate.
-
-*How to prove it:* Driver: enter ROUTE_26_HEAL_HOUSE with a damaged party, talk, assert full heal and that the scene is repeatable.
-
-*Notes:* Doc rating: unverified/minor, new.
-
-
-### Victory Road item pickups (TM26 Earthquake pit, Full Restore shelf, Max Revive, Full Heal, X Special, two hidden items) never exercised
-
-walkthrough section(s) 17 | unverified
-
-The walkthrough collects five Poke Ball items (TM26 Earthquake via the one-way pit at (0,11), Full Restore on the ledge shelf via the (17,19) ladder, Max Revive and Full Heal in the entrance region, X Special on the HOP_LEFT column) plus two hidden items (Max Potion at (3,29), Full Heal at (3,65)). All pieces exist: cache maps.VICTORY_ROAD carries 6 objects (5 with itemball item/qty payloads), 2 bgEvents with hiddenItem tables, 10 warps, 2 coord events; World:interact consumes obj.itemball (World.lua:5483-5490, an earlier bot-found fix); HiddenItems handles BGEVENT_ITEM; Permissions models the COLL_PIT one-way warp, the six ladders, ledge hops (isLedge/ledgeFacings, Gold's own direction order where $a0 is HOP_RIGHT), and COLL_UP_WALL side walls (Permissions.lua:170-260 LEDGE_FACINGS/SIDE_BLOCKS/NEIGHBOR_ARM), with a test section at tests/gen2_world_test.lua:2936. But nothing has walked these routes: the bot's section 17 is only travel/walk rows 17.2, 17.11, 17.15 (no pickup rows), so the pit drop, the two HOP exits from the TM pocket, the HOP_DOWN off the shelf, and the X Special ball sitting ON a HOP_LEFT tile (the one placement the asm-walk flags as needing hardware confirmation) are all unproven end to end.
-
-*How to prove it:* Driver or route rows through Victory Road collecting all five balls and both hidden items, specifically exercising the (0,11) pit drop, the (17,19) ladder shelf with HOP_DOWN exit, the two HOP exits from the TM pocket, and interaction with the X Special ball on its HOP_LEFT tile.

+## 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.

+# 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.

+`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`.
+
+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 shape or the meaning of an
+existing field. 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.

+# RFC 0006 — Selected title playthrough storage and checkpoint resume
+
+## Status
+
+Proposed. Engine: `SaveData.lua`, `Storage.lua`, `Checkpoint.lua`, and
+`Loader.lua`. Tests: `title_playthrough_context.lua`, existing storage,
+checkpoint, title, save-slot, and no-mod parity suites.
+
+## Motivation
+
+A tool checkpoint may be the first durable record of a new playthrough. The
+engine intentionally keeps normal Pokémon SAVE independent: before the first
+normal write, identity is retained by the engine-owned selected-slot mapping,
+while title starts with a fresh New Game skeleton. A durable checkpoint tool may
+explicitly create one ordinary progress anchor after its first checkpoint has
+committed; later tool writes must remain independent. Calling ordinary active
+`mod.storage` there would allocate/adopt an identity, and live
+`mod.checkpoints:restore` correctly refuses title because it has no gameplay
+rollback state. Generic public capabilities are required; a tool must not use
+private storage paths, slot ids, or simulate the player's SAVE menu flow.
+
+## Additive public API
+
+### `mod.storage:selected(game)`
+
+Available only while the engine is in a title session. Returns an opaque bound
+facade or `nil, code, message`:
+
+```lua
+local selected = mod.storage:selected(game)
+local context = selected:context()
+local history = selected:read("history/index")
+```
+
+The facade exposes `context()`, `read(key)`, `write(key, value)`,
+`list(prefix)`, and `delete(key)`. It is bound internally to the launcher-
+selected existing game-version/playthrough and the calling mod id. It neither
+accepts an arbitrary playthrough id nor reveals a slot id, filesystem path, or
+another mod namespace. Resolution is read-only; no selected mapping means
+`no_selected_playthrough`, and opening a title browser never mints an identity.
+Its detached context can include only `normalSavedAt` from a matching ordinary
+save, so title tools can apply their own resume policy without receiving the
+canonical normal-save record.
+
+### `mod.checkpoints:ensureNormalSave(game, checkpoint)`
+
+Available only at a live checkpoint-safe boundary. After a tool has durably
+committed the supplied current checkpoint, it may request an ordinary progress
+anchor for a playthrough that has never had one. The engine validates the
+checkpoint, proves it exactly matches a fresh capture of the live runtime, and
+uses the normal atomic save path including `save.write` lifecycle/veto hooks.
+
+The operation is idempotent. It returns `true, "already_exists"` without writing
+when matching normal progress already exists, so later checkpoints never move
+the vanilla CONTINUE target. A stale/non-current checkpoint, unsafe runtime,
+write veto/failure, or failed readback returns a structured failure. A tool
+should call it only after its own checkpoint and index are durable and must not
+report that first checkpoint as successful if the required anchor fails.
+
+### `mod.checkpoints:resume(game, checkpoint)`
+
+Available only from title. It validates format, data-only structure, selected
+game/playthrough identity, canonical save/content, overworld/battle runtime, and
+RNG exactly as `restore` does. It then reconstructs semantic overworld or a
+supported battle continuation, preserves current options, and differentially
+recaptures before committing. On success it emits `checkpoint.restored` once.
+
+Title has no live runtime rollback. A reconstruction or verification failure
+therefore rebuilds a clean title session from the pre-operation title save and
+RNG; it emits no success event and never rewrites normal progress. Validation
+failure leaves the existing title session untouched. Stable errors include
+`not_at_title`, `no_selected_playthrough`, normal checkpoint validation codes,
+`resume_failed`, and `title_recovery_failed`.
+
+## Isolation and migration
+
+Explicit NEW GAME retains its existing fresh-identity rule. It does not reuse a
+previous selected mapping and cannot see old tool history. Existing mods change
+nothing: no identity, storage, title reconstruction, or event is created unless
+the new methods are called. `mod.storage` remains independent durable data and
+does not rewind with a checkpoint; canonical `game.save` / `mod.save` does.
+
+## Verification
+
+The public SDK test starts a fresh playthrough, stores tool history, creates and
+readback-verifies exactly one normal anchor, proves subsequent calls do not
+rewrite it, simulates title/restart, reads the selected binding without
+allocating title identity, resumes an overworld checkpoint, preserves options,
+differentially recaptures, and confirms a later explicit NEW GAME receives
+another identity. A separate two-process disk test proves cold-start routing and
+reconstruction. Existing no-mod, storage, checkpoint, battle, and title suites
+prove additive parity.

+# RFC 0007: Battle menu auxiliary actions
+
+## Status
+
+Proposed.
+
+## Problem
+
+Tool mods can inspect/capture a persistent checkpoint only at a settled
+ordinary wild/trainer player-decision boundary. Before this proposal, that
+boundary had no public semantic input/action seam: `BattleState` consumed the
+command loop directly. A mod could reach it only through private battle/input
+internals, which would be unsafe and incompatible with controller/touch input.
+
+## Contract
+
+`mod.hooks:wrap("battle.menu_auxiliary", callback)` is called only when START
+is pressed at the existing checkpoint-safe player-decision boundary. The
+callback signature is:
+
+```lua
+function callback(next, game, context)
+  -- context is { kind = "wild" } or { kind = "trainer" }
+  -- return true after claiming START, otherwise return next(game, context)
+end
+```
+
+The context is data-only. No live battle controller, input object, serializer,
+or restoration primitive is exposed. A `true` result consumes START for that
+fixed step without selecting a battle command. With no installed handler,
+START is inert exactly as before. Hook priorities and error isolation are the
+existing generic wrapper semantics: a throwing handler is skipped and cannot
+advance battle state.
+
+The engine reuses the same internal safety predicate as battle checkpoint
+capture. Link, Safari, ghost/demo, unsupported origins, scripts, queues,
+animations, messages, forced replacement/locked actions, and unsettled HP or
+status presentation never invoke the hook.
+
+## Compatibility and verification
+
+The call is additive and no-op with no handler. ROM-free engine tests prove
+wild/trainer delivery, cursor/turn preservation, and unsafe-phase refusal;
+the mod-SDK fixture proves a loaded mod can consume the semantic action using
+only its public hook facade. `gate_hooks` automatically includes the new call
+site in no-mod parity coverage.

+/**
+ * A TLS client socket that Lua can drive without ever blocking a frame.
+ *
+ * WHY THIS EXISTS. LuaSocket, which is what LOVE ships, speaks TCP and nothing
+ * else, so wss:// was simply unreachable from the game -- and every room hosted
+ * on archipelago.gg is TLS-only, accepting a plain connection just long enough
+ * to drop it. The alternative was vendoring mbedTLS into the NDK build and
+ * carrying a CA bundle in the APK; the platform already has both a TLS stack
+ * and the system trust store, so this asks Android instead.
+ *
+ * THE CONTRACT. Callers get an int handle and poll it. open() returns
+ * immediately and the connect and handshake happen on their own thread, so a
+ * slow or unreachable host costs nothing on the game thread -- which matters
+ * more here than it did for httpDownload, since that runs on a worker and this
+ * is serviced from the frame loop. Bytes handed to send() before the handshake
+ * finishes are queued, not refused, so a caller can write its request the
+ * moment it has a handle and never think about readiness again.
+ *
+ * Reads are drained by a thread into a chunk queue and handed over a copy at a
+ * time; a caller that stops polling stops the connection rather than growing
+ * the heap without limit.

+  `osx-arm64` when those builds are wired up
+
+## Build
+
+```powershell
+dotnet publish native/tls_dial/Gen1Tls.csproj -c Release -r win-x64 -o dist/native/win-x64
+```
+
+The Windows game zip script already does this:
+
+```powershell
+powershell -ExecutionPolicy Bypass -File scripts/build_windows.ps1 -Version 0.1.77
+```
+
+Ship `gen1tls.dll` (or `libgen1tls.so` / `libgen1tls.dylib`) **next to** the
+fused executable. Mods load it through LuaJIT FFI; no .NET runtime is
+required on the player's machine.
+
+## Android
+
+On Android, the matching API is exposed as `love.system.tlsOpen` /
+`tlsStatus` / `tlsSend` / `tlsReceive` / `tlsError` / `tlsClose`, backed by
+`org.love2d.android.TlsSocket`.
