From 01a77f043afbd6509a953eb03e6db111c55ae92b Mon Sep 17 00:00:00 2001 From: Joey Yakimowich-Payne Date: Mon, 27 Apr 2026 15:22:18 -0600 Subject: [PATCH] feat(thressgame-100): Wave 2 \u2014 multi-turn state + 10 countdown recipes + e2e Wave 2 of thressgame-100 epic complete. Coverage 27/51 \u2192 37/51 = 72 % (on plan target). ENGINE WORK (W2.0\u2013W2.6): - New trigger primitive on-attr-expire(target, attr, primitives) \u2014 fires when an attr countdown hits zero. Introduces 'expiringValue' binding to inner primitives. - New imperative primitive decrement-attr-each-turn(target, attr) \u2014 explicit countdown control (alternate to set-piece-attr.lifetime: turns). - New dispatcher stage 13 fireAttrExpireHooks \u2014 batched per-turn-boundary, runs AFTER stage 12 fireOnTurnStartHooks. - Lifetime registry extension (lifetime-registry.ts) \u2014 decrementAttrCountdowns function mirrors the marker-lifetime pattern; fires on-attr-expire BEFORE retraction so triggers can still read the expiring value. - Schema additions (schema.ts) \u2014 OnAttrExpireHooks (game-level on GAME_ENTITY), AttrCountdownRegistry (game-level), OnAttrExpireHookEntry, AttrCountdownEntry. - Validator (validate.ts) \u2014 decrement-attr-each-turn added to IMPERATIVE_KINDS; on-attr-expire registered as binding-introducer with FIXED_BINDING_KINDS map. - IMPERATIVE_KINDS list and trigger-scope walker updated. 10 NEW RECIPES (W2.7\u2013W2.9): - tpl-time-bomb \u2014 black knights self-destruct after 5 turns - tpl-nuclear-fallout \u2014 3 random blocked-square markers (deterministic seed) - tpl-christmas-truce \u2014 BlockAllExceptKing on GAME_ENTITY for 3 turns (proxy for missing BlockAllCaptures attr) - tpl-pawn-second-chance \u2014 captured white pawn returns 1 turn later - tpl-invulnerability-potion \u2014 white pieces uncapturable for 3 turns - tpl-anti-camping \u2014 every piece dies after 3 turns (refresh-on-move arm dropped per depth limit) - tpl-ice-age \u2014 16 frozen-square markers covering files a + h - tpl-no-cowards \u2014 MustMoveForward semantic flag for 1 turn - tpl-drafted-for-battle \u2014 chooser picks bishop/knight, swap with king - tpl-corporate-ladder \u2014 chooser picks 2 pieces to swap NINE DOCUMENTED SIMPLIFICATIONS (full rationale in notepad and evidence): - tpl-time-bomb dropped adjacent-splash arm (depth 5 > MAX_RECURSION_DEPTH=3) - tpl-christmas-truce uses BlockAllExceptKing (no BlockAllCaptures attr) - tpl-pawn-second-chance white-pawn-only (place-piece pieceType/color strict) - tpl-invulnerability-potion uses set-piece-attr (set-capture-flag has no target) - tpl-anti-camping dropped refresh arm (depth limit) - tpl-no-cowards ships flag only (move-gen consumer wiring deferred to host preset) - tpl-corporate-ladder uses request-choice(piece) \u00d7 2 (square \u2192 pieceId conversion isn't expressible in ConditionSpec.value) - tpl-drafted-for-battle bishop/knight restriction is player discipline - tpl-nuclear-fallout / tpl-ice-age use lifetime: moves (spawn-marker.lifetime schema doesn't accept turns) TEST SURFACE: - on-attr-expire.test.ts: 12 unit tests - decrement-attr-each-turn.test.ts: 10 unit tests - attr-expire-integration.test.ts: 7 integration tests (incl.

The decrementer (`util/lifetime-registry.ts#decrementLifetimes`) was running at stage 11b (between `fireOnTurnEndHooks` and `fireOnTurnStartHooks`) and silently retracting expired facts WITHOUT firing any trigger. +- **What changed**: extended the existing sweep to fire `on-attr-expire` BEFORE retracting (mirror of T19's `decrementMarkerLifetimes` "fire BEFORE remove" precedent), and RELOCATED the call to a new stage 13 (after `fireOnTurnStartHooks`) per locked decision D in `decisions.md`. Added a SECOND sweep (`decrementAttrCountdowns`) for the new explicit `decrement-attr-each-turn` registry (`AttrCountdownRegistry` on GAME_ENTITY). + +### What this task added + +- **2 new primitives** registered in `PRIMITIVE_REGISTRY` (50 → 52): `on-attr-expire` (trigger; seeds `OnAttrExpireHooks` on GAME_ENTITY filtered by exact `(target, attr)` match), `decrement-attr-each-turn` (imperative; appends `AttrCountdownEntry` to `AttrCountdownRegistry`). Both registered in `index.ts` barrel; `decrement-attr-each-turn` added to `IMPERATIVE_KINDS`. +- **2 new schema attrs**: `OnAttrExpireHooks` (hook list, `OnAttrExpireHookEntry[]`), `AttrCountdownRegistry` (registry list, `AttrCountdownEntry[]`). Both consumer-registered in `apply.ts` for the load-time integrity check. +- **1 new dispatcher stage**: stage 13 invokes both lifetime-registry sweeps — `decrementLifetimes` (existing, now firing trigger) + `decrementAttrCountdowns` (new). Order locked: lifetime first, countdown second. +- **1 new event variant**: `PrimitiveEvent.kind === "attr-expire"` carries `{entityId, attr, expiringValue}`. `expiringValue` is the attr's last value before retraction — for explicit countdowns that's the PRE-decrement value (so authors see "1" rather than the trivial "0" sentinel). +- **1 new fixed-binding mechanism in validator** (`FIXED_BINDING_KINDS` map in `validate.ts`): `on-attr-expire` always introduces `expiringValue` into the lexical scope of its `primitives` child slot. Distinct from `BINDING_INTRODUCING_KINDS` (which reads the bind-name from a per-node param) — fixed bindings are dispatcher-injected. + +### Backward-incompat tests updated (per decision J) + +- **`registry-count.test.ts`**: 50 → 52 (2 new primitives). +- **`ParamField.snapshot.test.tsx`**: `SAMPLE_PARAMS` map updated to include the two new primitive kinds (TS coverage requirement — `Record` exhaustiveness). +- **`apply.test.ts`**: comment-only update on `EXPECTED_ORDER` to document stage 13. The spy list is unchanged; the new dispatcher invocation runs through `decrementLifetimes` / `decrementAttrCountdowns` indirectly via `fireAttrExpireHooks`, which the existing `firstOccurrences` reducer ignores. + +### Walker-artifact safeguard re-applied + +- `on-attr-expire.apply()` seeds the GAME_ENTITY hook list FIRST, before the walker recurses into `params.primitives`. Inner primitives that contain ctx-* shapes will throw if walker-recursed at outer scope (no `expiringValue` binding visible), but the hook seed persists so the dispatcher fires correctly at runtime. Mirrors the W1.11 walker-artifact pattern locked by `on-piece-entered-marker`. + +### Perf budget result (countdowns-perf.test.ts) + +- 100 in-flight countdowns (50 lifetime + 50 explicit) × 1000 moves: p50=13.6ms, p99=24.6ms, max=36.9ms. Active enforced budget: 150ms p99 — comfortably within. Aspirational-budget gap (~25ms vs 150ms) leaves headroom for cascade-heavy descriptors that haven't been benchmarked yet. + +### Test count delta + +- `bun run check`: 3010 → 3040 tests (+30). 0 regressions. +- New files: `on-attr-expire.test.ts` (12 tests), `decrement-attr-each-turn.test.ts` (10 tests), `__tests__/attr-expire-integration.test.ts` (7 integration tests including determinism @ N=100), `__fixtures__/perf/countdowns-perf.test.ts` (1 perf test). + +## [2026-04-26] W2.7-W2.9 — 10 Wave-2 recipes + runtime tests + +### Recipes shipped (36 → 46) + +- Batch D — countdowns (5): `tpl-time-bomb`, `tpl-nuclear-fallout`, `tpl-christmas-truce`, `tpl-pawn-second-chance`, `tpl-invulnerability-potion`. +- Batch E — restrictions with duration (3): `tpl-anti-camping`, `tpl-ice-age`, `tpl-no-cowards`. +- Batch F — verified-shippable choosers (2): `tpl-drafted-for-battle`, `tpl-corporate-ladder`. + +Final recipe count: **46**. None of the originally-planned recipes was skipped. + +### Simplifications shipped vs. plan + +- **`tpl-time-bomb`** — original intent was 5-turn countdown → adjacent splash AOE (-99 Hp on neighbours via for-each-adjacent + add-to-attribute) THEN self-destruct. The composed shape `on-rule-activated → for-each-piece → on-attr-expire → for-each-adjacent → add-to-attribute` is **5 levels deep**, exceeding `MAX_RECURSION_DEPTH = 3` (validate.ts § walkPrimitiveNodes). Pragmatic fallback: drop the splash arm; on-attr-expire's inner is just `destroy-piece({ctx-self-id: null})`. The countdown→expire→self-destruct demonstration of the new W2.0-W2.6 lifetime subsystem is preserved cleanly at depth 3 (on-rule-activated → for-each-piece → on-attr-expire → destroy-piece). Splash AOE on countdown-expiry will need a flatter authoring shape (probably hoisting on-attr-expire to top-level with literal targets) — left as future work. +- **`tpl-nuclear-fallout`** — the original spec accepted a documented simplification re: `random-pick → spawn-marker.square` resolver chain. Shipped as 3 sibling random-picks (mirrors `tpl-minefield-full`'s 5-mine pattern). Lifetime is `{kind: "moves", expiresAtMove: 10}` (5 fullmoves from a fresh-game start), NOT `{kind: "turns"}` — `spawn-marker.lifetime` schema accepts only `permanent | moves | one-shot` (decrement-attr-each-turn semantics are per-piece-attr, NOT per-marker-entity). +- **`tpl-christmas-truce`** — no game-level `BlockAllCaptures` attr exists in the schema. Documented fallback: write `BlockAllExceptKing=true` on `GAME_ENTITY` with `lifetime: {kind: "turns", count: 3}`. Captures are a strict subset of moves; this acts as a coarse-grained truce. +- **`tpl-pawn-second-chance`** — locked decision is that `place-piece.pieceType/color` are STRICT literal enums (no resolver shapes — see `place-piece.ts:110-111`). Cannot copy a captured piece's class from a $var-bound id. Documented fallback: ship as `tpl-pawn-second-chance` (white pawns only); respawn a white pawn at the dying piece's last Position. Used a clever 2-attr split (`SecondChancePosition` carries the square as a piece-attr value, `SecondChanceTurns` carries the countdown — both with parallel `turns:1` lifetimes so they're swept simultaneously). The on-attr-expire arm reads `SecondChancePosition` via `ctx-attr` to get the respawn square. +- **`tpl-invulnerability-potion`** — `set-capture-flag` writes to `ctx.pieceId` only (no target redirect), and CaptureFlags is a bitfield (the OR semantic in set-capture-flag.apply is per-piece-mutation). For the "every white piece for 3 turns" pattern we use `set-piece-attr({attr: "CaptureFlags", value: 2, lifetime: turns:3})` which OVERWRITES (not OR) — pieces with prior flags lose them for the duration. Documented in summary; locked trade-off. +- **`tpl-anti-camping`** — original spec wanted a refresh-on-move arm (`on-move → set-piece-attr` resets DormantCountdown to 3 on every move). Refresh logic across every piece would need separate per-piece on-move plumbing; pragmatic shape: the activation arm seeds `DormantCountdown=true` with `lifetime: turns:3` on EVERY piece, plus an `on-attr-expire` per piece that destroys it. No refresh; effectively "every piece dies after 3 turns" — a doomsday rule. The lifetime-driven expire pattern IS the demonstrated W2 subsystem; the refresh arm is future work. +- **`tpl-no-cowards`** — full implementation requires move-gen integration consumers don't have. Shipped as a SEMANTIC FLAG: GAME_ENTITY gets `MustMoveForward=true` with `lifetime: turns:1`. Host presets that consume MustMoveForward see the flag for one turn. Without consumer wiring it's a marker attr only — but it demonstrates the "transient game-level flag" pattern. +- **`tpl-corporate-ladder`** — original spec wanted `request-choice(square) × 2 → swap-pieces` (2 squares, swap their resident pieces). Problem: `request-choice kind:"square"` returns a square integer, not a piece id; `swap-pieces.a/b` accepts numeric resolvers, but converting square→pieceId requires a `Position`-comparison predicate inside `conditional`, and `ConditionSpec.value` is locked to literal `string|number|boolean|null` (no resolver shapes — see `schema.ts:111`). Pragmatic fallback: `request-choice kind:"piece"` × 2 + swap-pieces. The chooser binding directly returns piece ids — clean. +- **`tpl-drafted-for-battle`** — `request-choice kind:"piece"` doesn't filter by piece type, so the "pick a bishop OR knight" intent isn't expressible at the schema level. Player discipline replaces engine-level filtering; documented in summary. + +### New runtime patterns discovered + +- **`on-attr-expire` dispatcher matches by EXACT `(target, attr)` tuple equality** (`triggers.ts:1374-1376`: `if (hook.target !== entityId) continue; if (hook.attr !== attr) continue`). A single hook entry only fires for ONE specific piece. To seed "any-piece" semantics at activation time, the recipe MUST iterate matching pieces inside the activation arm and seed one hook entry PER piece — the on-attr-expire primitive lives inside the for-each-piece loop, with `target: { $var: "p" }` resolving to each iteration's bound id (the param-resolver substitutes resolver shapes BEFORE on-attr-expire.apply() runs, per `param-resolver.ts § resolveParams`). +- **MAX_RECURSION_DEPTH=3 forces composition flattening for countdown recipes.** Composed shape `on-rule-activated → for-each-piece → on-attr-expire → ` is at the depth 3 limit; `` MUST be a single flat primitive list. For richer reactions (splash damage, complex effects), authors must hoist on-attr-expire to top-level with a literal target (which only covers known-id pieces) OR redesign with a separate descriptor. +- **`spawn-marker.lifetime` accepts permanent/moves/one-shot, NOT turns** (per `spawn-marker.ts:90-97` LIFETIME_SCHEMA). The `turns` lifetime variant is per-piece-attr only via `set-piece-attr`. Recipes wanting turn-bounded markers use `{kind: "moves", expiresAtMove: }` — the absolute target is `currentFullmove + N`. For activation-time seeding from a fresh game (FullmoveNumber=1), this is `1 + N - 1 = N` fullmoves of life... actually decrementMarkerLifetimes retracts when `FullmoveNumber > expiresAtMove`, so a marker spawned at fm=1 with expiresAtMove=10 lives 9 fullmove ticks. Empirically verified via tpl-ice-age test — markers ARE present after activation and would be retracted at fm=11. + +### Test-harness conventions + +- **Two test patterns coexist** in wave2-recipes-real.test.ts: + 1. **Static-arm tests** drive the inner trigger arm directly via `runPrimitives` — single-fire semantics, no double-walker artifact, asserts seeded state immediately. Used for 8 of 10 recipes. + 2. **Lifetime-driven integration tests** use `new ChessEngine({profile: NOOP_PROFILE})` so the integration preset's onAfterMove dispatcher attaches and stage-13 fires at every move. We seed the lifetime/hook state manually (mirroring `attr-expire-integration.test.ts`'s harness) then drive `applyTurnPair` to advance fullmove ticks and assert post-expiry state. Used for 2 recipes (`tpl-time-bomb`, `tpl-christmas-truce`, `tpl-invulnerability-potion`). +- **`clearBoard(engine, {preserveKings: false})`** is required for "exact piece count" assertions — the default `preserveKings: true` leaves white + black king on the board (2 extra pieces) which corrupts `for-each-piece` → seed-counting assertions (anti-camping seeds a hook per piece; if kings remain, the count is +2). +- **GAME_ENTITY-level lifetime sweep is attr-agnostic.** The dispatcher's stage-13 sweep retracts ANY `(entity, attr)` pair whose `expiresAtTurn` matches the current fullmove. For tests that need to advance fullmove ticks WITHOUT triggering a real game-state-changing attr (like `BlockAllExceptKing` which would block move-gen), use a benign proxy attr name (`TruceProxyMarker`) for the same lifetime registry entry — the sweep mechanism is the test target, not the attr's downstream effect. +- **`PrimitiveEvent.kind` for on-captured arms is `"capture"`, NOT `"captured"`.** Both on-capture and on-captured triggers consume the same event kind; the `(attackerId, defenderId)` pair disambiguates which side the trigger fires on (see `context.ts:101-115`). TS error TS2820 surfaces immediately if you try `kind: "captured"`. + +### Test count delta + +- `bun run check`: 3040 → 3055 tests (+15). 0 regressions. +- New file: `wave2-recipes-real.test.ts` (15 tests covering all 10 recipes + 1 cross-cutting smoke for the registry). +- recipes.test.ts: 5 tests, 378 expect calls (5 invariants now apply to 46 recipes vs 36). + +## [2026-04-26] W2.10 — Playwright e2e for the 10 Wave-2 recipes + +- **All 13 tests green on first run** in 16.2s on the docker compose dev stack via `.sisyphus/scripts/run-pw.sh` (10 load-and-validate + 3 runtime). Spec at `packages/chess/e2e/wave2-countdowns.spec.ts`. Helper log: `/tmp/pw-w2-10.log`. +- **Runtime test depth decisions**: + - `tpl-ice-age` — full runtime (smoke variant). `applyDescriptor` fires the on-rule-activated arm; the walker double-fires on trigger primitives (selfRecurse !== true), so 16 spawn-marker primitives produce up to 32 frozen-square markers post-activation. Asserted `>= 16` lower bound + `<= 32` upper bound. Pin works because spawn-marker is non-idempotent and the double-fire is a documented walker artifact (see W1.11 § march-of-the-pawnguins). + - `tpl-nuclear-fallout` — full runtime (smoke variant). Same walker double-fire concern — 3 random-pick → spawn-marker primitives produce up to 6 blocked markers. Asserted `>= 3` lower bound + `<= 6` upper bound. The lower-bound smoke is sufficient because `wave2-recipes-real.test.ts` pins the exact 3-marker contract at the unit level by driving `runPrimitives` directly on the inner arm. + - `tpl-drafted-for-battle` — full runtime via `__test__.activate-descriptor` lift (NOT apply). The lift handler synthesizes the PendingChoice frame the dispatcher would push on activation, so `RequestChoiceModal` renders synchronously with `data-choice-kind="piece"`. Same mechanism `tpl-mind-control` uses in `templates-thressgame.spec.ts`. +- **Countdown-advance tests SKIPPED** (per task brief): countdowns `tpl-time-bomb`, `tpl-pawn-second-chance`, `tpl-invulnerability-potion`, `tpl-christmas-truce`, `tpl-anti-camping` ship with load-and-validate only at the e2e layer. The countdown contract (lifetime sweep at stage 13, on-attr-expire firing) is pinned at the unit/integration level by `wave2-recipes-real.test.ts` and `attr-expire-integration.test.ts`. Driving N fullmove ticks deterministically through the WS protocol is unreliable enough that adding it would more likely surface false-flake than recipe regression. +- **`data-marker-kind` for non-special markers**: Board.tsx line 388 — the default switch case renders `
` so `blocked` / `pit` / `tornado` / `treasure` / `death-square` all surface their marker-kind through the same selector. Frozen-square / mine / portal-end have explicit DOM nodes (lines 369/376/385). +- **Test count delta (e2e only)**: wave2-countdowns.spec.ts ships 13 tests.

Authors don't see the countdown remainder. + * + * - `decrement-attr-each-turn(target, attr)` — EXPLICIT. The + * attr value IS the countdown remainder (must be numeric); + * the registry just records "decrement this every turn"; the + * sweep mutates the attr value itself; expiry condition is + * `value <= 0` after decrement. Authors can read / display + * the remainder mid-flight. + * + * Use the LIFETIME shape for "this fact is true for N turns then + * false again". Use this PRIMITIVE for "this number ticks down + * visibly each turn and fires when it reaches zero" (time bombs, + * shot clocks, anti-camping). + * + * ## Imperative gating (T14) + * + * `decrement-attr-each-turn` is in {@link IMPERATIVE_KINDS}. The + * descriptor-tree validator rejects top-level placement of + * imperative primitives — this primitive is legal ONLY inside a + * trigger arm (`on-rule-activated.primitives`, + * `on-piece-entered-marker.primitives`, etc.). Mirrors the gating + * applied to `set-piece-attr` (T26). + * + * ## Move-gen dry-mode (T20) + * + * Under `ctx.suppressTriggers === true`, the dispatcher skips + * imperative primitives entirely. We do NOT branch on the flag + * here — single source of truth lives at the dispatcher. + * + * ## Param resolution + * + * `target` and `attr` accept `numberOrResolver()` / + * `stringOrResolver()`. The walker substitutes `$var` / + * `ctx-self-id` / arithmetic shapes to literal values BEFORE this + * `apply()` runs, so the schema only needs to accept the + * fully-resolved ground forms at storage time. + * + * ## Idempotency + * + * Calling this primitive twice on the same `(target, attr)` pair + * appends two entries — both ticking the attr once per sweep + * (effectively decrementing by 2/turn). This matches the low-level + * mutation contract of `registerLifetime` (T35) which does not + * dedup on registration. Authors who need exactly-once semantics + * should gate the call inside a `conditional` that checks for the + * existing registry entry — but that pattern is rare; the typical + * use case (one descriptor seeds the countdown via + * `on-rule-activated`) doesn't double-register. + */ +import { z } from "zod"; +import type { EntityId } from "@paratype/rete"; +import { + GAME_ENTITY, + type AttrCountdownEntry, + type ChessAttrMap, +} from "../../schema.js"; +import { + numberOrResolver, + stringOrResolver, +} from "./param-resolver-schema.js"; +import { PRIMITIVE_REGISTRY } from "./registry.js"; +import type { EffectPrimitive, PrimitiveApplyContext } from "./types.js"; + +const schema = z.object({ + target: numberOrResolver({ min: 0 }), + attr: stringOrResolver(), +}); +type Params = z.infer; + +const descriptor: EffectPrimitive = { + kind: "decrement-attr-each-turn", + label: "Decrement Attribute Each Turn", + description: + "Marks a (target, attr) pair as a per-turn countdown; the engine decrements the attr each turn-end and fires on-attr-expire when it reaches zero.", + longDescription: + "Tags a numeric value on a piece (or on the game) as a countdown that ticks down by one every turn.
