From d4931a50ee3e45f327a98a6f1caab0d415977ecb Mon Sep 17 00:00:00 2001 From: Joey Yakimowich-Payne Date: Sun, 26 Apr 2026 11:54:24 -0600 Subject: [PATCH] feat(thressgame-coverage): Wave 8 (WS protocol v2 + suspended execution + request-choice) - T43: WS protocol v2 schema; protocolVersion field; RequestChoice/SubmitChoice/ProtocolVersionMismatch messages; v1 backward-compat - T44: server-side request-choice broadcast on push; submit-choice validation (kind/forPlayer/value-type); ordered LIFO matching - T45: PendingChoices stack on GAME_ENTITY; pushPendingChoice/popPendingChoice/peekPendingChoice helpers; serializePendingChoice (Map<->Array roundtrip); MAX_CHOICE_DEPTH=8 enforced - T46: submitChoiceAndResume(engine, choiceId, value); descriptor-by-id lookup; bindings restored; remaining primitives executed via runPrimitives from primitiveIndex+1 - T47: request-choice primitive; SuspendedExecution exception mechanism; dispatcher catches and stops sibling iteration; deterministic choiceId via session counter - T48: AutoChoiceResolver test transport (answersByKind / answersById); drainPendingChoices LIFO walk - T49: server-side choice timeout enforcement; auto-resolve to first-option-per-kind; disconnect handler (forfeit / pause) - T50: ChoiceTimeoutPolicy on GAME_ENTITY (timeout-with-default | no-timeout); CreateGameRequest extended; default 60s Tests: 2533 -> 2658 (+125). bun run check exit 0. --- .sisyphus/boulder.json | 48 +- .../visual-modifier-builder/learnings.md | 43 ++ .sisyphus/plans/thressgame-coverage.md | 16 +- .../choice-transport/auto-resolver.test.ts | 156 ++++ .../choice-transport/auto-resolver.ts | 191 +++++ .../chess/src/engine.choiceTimeout.test.ts | 64 ++ packages/chess/src/engine.ts | 34 + packages/chess/src/index.ts | 23 + packages/chess/src/modifiers/apply.ts | 27 + .../chess/src/modifiers/custom/validate.ts | 18 +- .../chess/src/modifiers/primitives/index.ts | 3 + .../primitives/registry-count.test.ts | 5 +- .../primitives/request-choice.test.ts | 457 +++++++++++ .../modifiers/primitives/request-choice.ts | 295 ++++++++ .../chess/src/modifiers/primitives/types.ts | 3 +- packages/chess/src/modifiers/triggers.test.ts | 74 +- packages/chess/src/modifiers/triggers.ts | 88 ++- packages/chess/src/schema.ts | 153 ++++ .../chess/src/ui/ParamField.snapshot.test.tsx | 154 ++++ packages/chess/src/ui/narrate.test.ts | 443 ++++++++++- .../src/ui/visual-builder/BlockCard.test.tsx | 97 +++ .../chess/src/ui/visual-builder/BlockCard.tsx | 29 +- .../src/ui/visual-builder/BlockList.test.tsx | 83 +- .../chess/src/ui/visual-builder/BlockList.tsx | 135 ++-- .../visual-builder/VisualBuilderPane.test.tsx | 26 +- .../ui/visual-builder/VisualBuilderPane.tsx | 381 ++++++---- .../src/util/pending-choices-resume.test.ts | 348 +++++++++ .../chess/src/util/pending-choices.test.ts | 232 ++++++ packages/chess/src/util/pending-choices.ts | 483 ++++++++++++ packages/server/src/broadcast.ts | 709 +++++++++++++++++- packages/server/src/choice-timeout.test.ts | 569 ++++++++++++++ packages/server/src/choice-timeout.ts | 302 ++++++++ packages/server/src/game-session.ts | 45 +- packages/server/src/protocol.test.ts | 506 +++++++++++++ packages/server/src/protocol.ts | 346 ++++++++- packages/server/src/rooms.ts | 19 + packages/server/src/ws.request-choice.test.ts | 531 +++++++++++++ 37 files changed, 6841 insertions(+), 295 deletions(-) create mode 100644 packages/chess/src/__fixtures__/choice-transport/auto-resolver.test.ts create mode 100644 packages/chess/src/__fixtures__/choice-transport/auto-resolver.ts create mode 100644 packages/chess/src/engine.choiceTimeout.test.ts create mode 100644 packages/chess/src/modifiers/primitives/request-choice.test.ts create mode 100644 packages/chess/src/modifiers/primitives/request-choice.ts create mode 100644 packages/chess/src/util/pending-choices-resume.test.ts create mode 100644 packages/chess/src/util/pending-choices.test.ts create mode 100644 packages/chess/src/util/pending-choices.ts create mode 100644 packages/server/src/choice-timeout.test.ts create mode 100644 packages/server/src/choice-timeout.ts create mode 100644 packages/server/src/ws.request-choice.test.ts diff --git a/.sisyphus/boulder.json b/.sisyphus/boulder.json index b251e9d..fe5f763 100644 --- a/.sisyphus/boulder.json +++ b/.sisyphus/boulder.json @@ -9,7 +9,53 @@ "ses_23783ab16ffeCNSrXoK1oU7I8s", "ses_2378026c8ffeZz47LuDzc1yyOK", "ses_237814da3ffetUoZjKTSOO0cB6", -

The dispatcher (`runPrimitives` in + * `triggers.ts`) catches the exception, fills in the missing + * `triggerPath` + `primitiveIndex` on the just-pushed frame, and + * stops iterating siblings — the rest of the surrounding arm is the + * "continuation" that T46 (`submit-choice`) will resume after the + * player picks. + * + * ## Why a thrown exception, not a return flag + * + * runPrimitives loops over `nodes[]`, calling each primitive's + * `apply()`. If apply() simply returned `void`, the loop would + * silently advance to the next sibling — the request-choice would + * push its frame and then the next sibling would still run, which + * is the OPPOSITE of suspension. The two ways to abort the loop + * cleanly are (a) a thrown exception caught at the dispatcher, or + * (b) a mutable side-channel on `ctx`. Option (a) is preferred + * here because it doesn't widen the public `PrimitiveApplyContext` + * surface with a new mutable field that every other primitive then + * has to ignore. See plan T47 § "Suspension mechanism". + * + * ## Why `triggerPath` + `primitiveIndex` come from the dispatcher + * + * The primitive itself does NOT know its own index inside the + * arm that's iterating it (the loop counter lives in + * `runPrimitives`), nor does it know the path of nested + * `then` / `else` / `primitives` slots leading to the current arm. + * The dispatcher owns both. So the primitive pushes a frame with + * placeholders (`triggerPath: []`, `primitiveIndex: 0`); the + * dispatcher's catch-block pops the placeholder, replaces those + * two fields with the real values, and re-pushes. This keeps the + * primitive's `apply()` contract free of dispatcher-internal state + * (it never reads or writes the loop counter directly). + * + * ## Deterministic `choiceId` + * + * `Date.now()` is forbidden by the plan's must-not-do list — would + * make the id wall-clock-dependent and break replay. We instead use + * `engine.rng().nextInt(...)` which advances the persistent + * `RngStream` fact on `GAME_ENTITY`. Two engines seeded identically + * and run through the same descriptor sequence produce the same id + * for the same choice (the locked T2 determinism contract). + * + * The id format is `choice--` so: + * - `descriptorId` makes the id self-describing in logs. + * - `rngHex` is a hex-encoded uint32 from the seeded RNG — + * uniqueness within a session is bounded by 2^32, sufficient + * for any plausible game (a typical game pushes < 100 choice + * frames; collision odds at that scale are negligible). + * + * ## Bindings + * + * The frame captures `ctx.bindings` at suspension time so the + * resume mechanism (T46) can rebuild a context that observes every + * outer iteration's `$var` scope. The frame's `bind` field (the + * name the player's answer will land under) is NOT part of + * `PendingChoice` — it's stashed in the captured `bindings` map + * via convention: T46 looks up `frame.bindings.get()` after + * inserting the player's answer under `params.bind`. + * + * Wait — actually the schema's `bindings` field is the SCOPE at + * suspension. The player's answer key (`params.bind`) is recorded + * separately in the {@link PendingChoice}? No — `PendingChoice` + * doesn't carry `bind`. The convention is: T46 reads the + * descriptor's primitive tree at `triggerPath`, finds the + * request-choice node, reads its `params.bind`, and writes + * `bindings.set(params.bind, playerAnswer)` before re-entering + * `runPrimitives`. That keeps the `PendingChoice` shape minimal. + * + * ## Imperative gating (T20) + * + * `request-choice` is NOT in `IMPERATIVE_KINDS` — it's a + * control-flow primitive, not a board mutator. Dry-mode probing + * still calls `apply()`, which means a what-if probe would push a + * pending frame and throw. That would corrupt the dry probe's + * state. The validator (T34) is responsible for forbidding + * `request-choice` inside primitives that the dry-prober walks + * through (e.g. inside `with-probability`'s arms — already locked + * by T34); for the dispatcher level, dry-mode never enters trigger + * dispatch in the first place (move-gen runs `attackProbe`, not + * the trigger pipeline).
