Estimated code review effort: 5 (Critical) | ~120 minutes Mergeability Score: 🟡 Moderate · up to This PR makes bounded loop shortcuts publish and validate declared counts, but a count can persist across offers and be applied to the wrong offer, producing an incorrect shortcut declaration.

ephemeral: boolparameter with a typed two-variant enum.
grid_template's third parameter selects betweenYieldTarget::ThisObject(per-incarnation, CR 400.7) andYieldTarget::AllCopies(latched card identity).

📐 Maintainability & Code Quality | 🟠 Major | ⚡ Quick win
The census cannot see a ninth clear site outside the two named files.
The loop iterates a hard-coded list, ["game/engine.rs", "types/game_state.rs"]. The doc states this row "fails loudly if a NINTH clear site is added without the journal", but a new loop_detect_ring.clear() in any other file under crates/engine/src is never read, so it is neither paired nor reported. The paired == 8 assertion still passes, and the guard reports green while the regression it exists to catch is live.
Walk crates/engine/src recursively instead of naming files, and keep the count assertion as the drift detector.

Request changes — the bounded declaration is not consumable by the browser path, and the new serialized surfaces are not version-gated.
🔴 Blocker
The bounded-loop declaration is published but deliberately discarded before a browser player can declare it. crates/engine/src/game/engine.rs:2393-2400 puts declaration on the bounded offer, while crates/engine/src/game/engine.rs:9392-9415 matches it as _ and passes only the client-supplied template to the handler. The registered DeclareShortcutModal always submits template: null at client/src/components/modal/LoopShortcutModal.tsx:65-72. For any nonempty schema, handle_declare_shortcut rejects that None unless the proposer owns the recorded period (engine.rs:6004-6050); the bounded producer's advertised alternative is the generated declaration, which the AI candidate path uses at crates/engine/src/ai_support/candidates.rs:3302-3317.
This creates different behavior for the same offer: AI can declare it, while a normal browser confirmation returns to priority. Please carry the engine-issued declaration through the manual action path after normal viewer filtering, and add a production-path regression test for a nonempty bounded offer that proves the browser payload reaches the accepted declaration rather than the None refusal. The existing modal assertions at client/src/components/modal/__tests__/LoopShortcutModal.test.tsx:60-83 currently lock in the broken null payload.
🔴 Blocker
This adds wire-visible fields without the coordinated protocol-version update. WaitingFor::LoopShortcut now serializes declaration (crates/engine/src/types/game_state.rs:11069-11114), and InteractionResponseSpec::Shortcut now publishes preview (crates/engine/src/types/interaction.rs:971-1057). P2P setup and state-update messages carry GameState (client/src/network/protocol.ts:117-159) but still advertise WIRE_PROTOCOL_VERSION = 20 (:115). The WebSocket protocol contract explicitly requires a lockstep bump when a variant gains a field (client/src/adapter/ws-adapter.ts:202-205), but the client, lobby, and server remain at v30.
Please bump the P2P and full-game protocol contracts together with their version-history/tests, or remove/defer these wire-surface additions until that compatibility change is included. Green current checks do not exercise an old/new peer pairing.
🟡 Non-blocking
The inventory expansion still silently overwrites one LayoutKind and suppresses filesystem traversal errors (crates/engine-inventory-gen/src/main.rs:85-90,100-127). Since the generated inventory is the discoverability authority, retain module-qualified identities and propagate WalkDir errors, or split this unrelated expansion from the shortcut work.
✅ Clean
I verified the current-head parse-diff artifact reports no card-parse changes and the CI rollup is green. Those results do not resolve the two runtime/transport gaps above.
Recommendation: repair the manual declaration and versioning paths, then request a fresh review on the new head.

🌐 Web query:
i18next 26 plural resolution missing few many key fallback other fallbackLng v4
💡 Result:
In i18next v26, plural resolution is handled exclusively by the Intl.PluralRules API [1][2]. There is no automatic fallback to the base key (e.g., 'key') if a specific plural form is missing [1][3]. Key points regarding your query: 1. Mandatory Plural Forms: i18next determines which plural categories (e.g., zero, one, few, many, other) are required for a given language based on standard CLDR rules [4][3]. If your translation JSON defines a key but is missing one of the specific suffixes required by that language, i18next will not automatically fall back to another suffix (like _other) or the base key [1][3]. It will fail to resolve the key, and you will encounter a missing key error [3]. 2. No Base Key Fallback: Passing a 'count' option to the translation function (t) instructs i18next to look for a key suffixed with the plural category (e.g., 'key_one', 'key_many') [1][3]. If you do not provide 'count', i18next looks for the literal key ('key') and will not attempt to resolve a plural form [1][3]. 3. Fallback Language (fallbackLng): If a key is missing in the current language, i18next will attempt to resolve it using the configured fallback language [5]. However, this applies to the key lookup itself, not to missing plural forms within a language [5]. If the plural form (e.g., 'key_many') is missing in your primary language, i18next does not automatically "fix" this by looking up 'key_other' or the base key; it treats the specific plural form as missing [3]. 4. Resolution: To ensure consistent behavior, you must include all required plural suffixes for each target language in your translation files [3][6]. You can verify which plural categories a language uses in your environment by running: new Intl.PluralRules('your-language-code').resolvedOptions.pluralCategories [3]. For troubleshooting, version 26 improves the missingKey debug logs to show the exact plural-resolved key being sought (e.g., 'key_many' instead of 'key'), making it clear which specific plural form is absent [7].

[HIGH] Loop-shortcut modal state is not scoped to the engine offer. Evidence: client/src/components/game/LoopShortcutModal.tsx:124-135 returns the modal without an offer identity key, while 154-159 preserves the typed iteration count in component state; GamePage keeps the modal mounted across offers. Why it matters: a typed count from one offer can be submitted for a distinct replacement offer. Suggested fix: expose an engine-issued offer identity and key/reset the modal from it; add a regression that replaces an offer after typing a count.
[HIGH] The macOS probe path bypasses the new platform contract. Evidence: Tiltfile:25-43 establishes IS_LINUX / PROBE_PIN_TRIGGER, but Tiltfile:529-532 runs probe-pin-census with ungated auto_init and no trigger_mode. Why it matters: macOS still runs a Linux-specific probe initialization path and the configuration no longer has one consistent platform policy. Suggested fix: apply the identical Linux gates to that resource and update its wording accordingly.
[MED] The engine-inventory generator claims parse failures propagate but silently discards them. Evidence: scripts/engine-inventory-gen/src/main.rs:118-120 promises errors propagate, while 131-136 swallows the syn parse error. Why it matters: inventory output cannot be the claimed complete authority if malformed source is omitted without a failure. Suggested fix: propagate the parse error with file context.

[HIGH] Scope the loop-shortcut picker state to the unique engine-issued offer. Evidence: GamePage persistently mounts DeclareShortcutModal (client/src/pages/GamePage.tsx:1886); the modal self-gates and returns an unkeyed DeclareShortcutOffer (client/src/components/modal/LoopShortcutModal.tsx:124-135), which owns picked state (:154-159). Why it matters: when a later engine offer replaces the first, the new offer can inherit the prior typed count instead of starting from its own suggestion. Suggested fix: have the engine publish a unique offer identity and use it as the React key for the offer picker; add a test that replaces offer A after typing with offer B with a different suggestion and verifies B starts fresh.

At current head e9c7fce0c5e257ea4617461a16eabaa7c13044e2, one unresolved blocker remains:
GamePage persists the DeclareShortcutModal mount (client/src/pages/GamePage.tsx:1886), while DeclareShortcutModal returns an unkeyed offer (client/src/components/modal/LoopShortcutModal.tsx:124-135). Its picked state (client/src/components/modal/LoopShortcutModal.tsx:154-159) therefore survives a replacement offer, allowing selection A to carry into a different suggested offer B.
Require a unique engine-issued offer identity and use it as the React key. Add a regression that types in A, replaces it with a different suggested B, and proves the replacement begins with fresh state.

… chokepoint `PersistedGameState::into_game_state` did not call `rehydrate_rng()`, so a native restore resumed with a word-0 ChaCha20 stream under a non-zero saved `rng_word_pos`. Any drive that shuffled then tripped `ResolvedRngReplayInvariantError::HighWaterRegression` (measured: `current: 313` on the Dina board, `current: 379` on the tracked F4 dump). The repair lived only in `engine-wasm`'s `restore_game_state`, so a load that ENDED at the chokepoint was left rewound; the chokepoint now does it and WASM's own call is an idempotent repeat (`rehydrate_rng` makes two absolute assignments). This does NOT make the shipped load paths equivalent. `server-core`'s `from_persisted` re-seeds with a fresh seed AFTER the chokepoint and never zeros `state.rng_word_pos`, so the server restore remains broken — a pre-existing gap this change neither caused nor repairs, disclosed in-code at the chokepoint and queued as a follow-up. A fourth caller, `phase-ai`'s `load_saved_game_state`, inherits the repair; it is offline bench/test tooling, so no shipped gameplay ingress changes behavior here. Adds `dina_noff_turn5_4p.json.gz` as a tracked fixture so the rows are runnable from the repo alone, derived from the archived pristine capture (844846 B, sha256 9843d5165cbbf7dd7bca4171c7888c190b7eba7e52a2ed095b44ff76fadd7886). Corrects the documentation this change falsifies. Three pre-existing loader doc comments described the chokepoint as covering both shipped ingresses without qualification. Two `engine-wasm` comments were falsified outright: one claimed `restore_game_state` "rewinds the stream to position 0", which `rehydrate_rng` never did; the other documented a revert-probe asserting that deleting either the export capture or the restore rehydration reds `export_then_restore_resumes_live_rng_stream_through_wasm_bridge`. Measured with five probe runs, neither restore-side deletion discriminates on its own — only deleting both does — so the comment now names the export capture as the single discriminator and discloses the double coverage. No `engine-wasm` code changed. Also drops a stale `types/game_state.rs:9024` coordinate in `triggers.rs` for a symbol anchor, and moves the new RNG rows out from under the R18 doc block they had silently detached from its test. Assisted-by: ClaudeCode:claude-opus-4.8
`GameSession::from_persisted` re-seeds `rng` from fresh entropy so restored
games do not all share one deterministic sequence, but left `rng_word_pos`
carrying the OLD stream's high-water. A fresh ChaCha20 stream starts at word 0,
so every restored server session that had ever shuffled came back with live 0 /
high-water <saved>, and its next `capture_rng_word_pos` — which
`game::library::resolve_and_apply_library_shuffle` performs before every shuffle
— `.expect`-panicked `HighWaterRegression`. Measured on the new row:
`HighWaterRegression { current: 291, requested: 0 }`.
A word offset is meaningless against a different keystream, so keeping it was
never conservative, it was incoherent. Zeroing it alongside the re-seed makes
the server restore structurally identical to `engine-wasm`'s
`resume_multiplayer_host_state`, which already implements this policy.
This closes the follow-up the preceding commit disclosed at
`PersistedGameState::into_game_state`. The six comments that described the
server path as broken are rewritten to describe what it now does, including the
two loader docs on the tracked F4 dump and the citation-gate-enrolled Kilo
loader; none is left pointing at a disclosure that no longer exists.
Two rows, both mutant-proofed by execution rather than argument. Deleting the
new statement reds `restore_reseeds_the_rng_and_drops_the_saved_stream_position`
with `291 != 0`; deleting it together with the guarding assertions reaches the
shuffle and reproduces the panic itself. The paired `#[should_panic]` row proves
that panic is reachable through the production seam on a restored session, so
"the shuffle succeeds" is evidence rather than a statement about a call that
could never have failed. `cargo test -p server-core` is covered by no Tilt
resource and was run directly: 344 passed.
DISCLOSED, NOT FIXED: `engine-wasm`'s `get_ai_scored_candidates` has the same
shape, in a worse form. It re-seeds `state.rng` inside `with_state_mut`, so the
rewind persists into the `GAME_STATE` thread-local, and it writes neither
`rng_word_pos` nor `rng_seed` — the state it leaves is incoherent on two axes,
and a later `rehydrate_rng` on it reconstructs the OLD stream, discarding the
scoring re-seed entirely. It is outside this change's frozen scope.
Reachability was measured rather than left open. No shipped client path reaches
the panic: `AiWorkerPool.getAiScoredCandidates` awaits `restoreState` on every
worker before each scoring call, `restore_game_state` rehydrates the full
triple, and the pool never hands out its workers. The exposure is the public
`#[wasm_bindgen]` surface — `EngineWorkerClient` does expose `exportState`, so a
host that exports a worker after scoring reaches `capture_rng_word_pos` and
panics. No bug on the shipped path today; a trap for the next caller.
The class-level repair is a single `GameState` method owning seed and offset
together. Four sites assign `state.rng` from a seed, but only three are
resume-class: `game::visibility::filter_state_for_viewer` is wire redaction and
already writes the whole triple deliberately. Of the three resume-class sites
this commit leaves two correct and only `get_ai_scored_candidates` defective, so
the helper is worth more now than when it was first declined — but this scope
reaches exactly one of them, so it stays a follow-up.

…oring
`get_ai_scored_candidates` re-seeded a pool worker's entropy stream by writing
`state.rng` alone. `rng` is `#[serde(skip)]`, so `rng_seed` and `rng_word_pos`
are its only carriers across a serialization boundary — writing one without the
others splits the stream identity in two.
The concrete failure: a fresh ChaCha20 stream starts at word 0, so a restored
state's surviving high-water leaves `advance_rng_high_water` guarding a position
the live cursor is behind. The next `capture_rng_word_pos` then `.expect`-panics
`HighWaterRegression` — and every simulated library shuffle performs one, as does
`export_game_state_json`. In the shipped build that surfaces as a worker-pool
failure and a silent fall back to degraded AI.
Reachability is verified in-call rather than argued: a test captures the panic's
backtrace inside the scoring call, along `score_candidates_for_parallel_worker`
-> `PlannerServices::quiesce` -> `apply_as_current_for_simulation` ->
`shuffle_library` -> `resolve_and_apply_library_shuffle` -> `capture_rng_word_pos`.
`scored_candidates_inner` is split out so native tests drive the real scoring
path: the `#[wasm_bindgen]` shell returns through `to_js`, which calls the real
`JSON.parse` binding and panics outside a wasm32 runtime — the same reason
`resolve_all_inner` exists. The new tests are `#[cfg(test)]`, deliberately not
`#[cfg(all(test, target_arch = "wasm32"))]`: that block's assertions never
execute in the native suite and no CI job runs `wasm-pack test`.
Executed mutant results, 25/25 cells as predicted (whole revert = M1+M2):
M1 delete `rng_word_pos = 0` A RED B RED C1 green C2 RED R3 RED
M2 delete `rng_seed = rng_seed` A green B green C1 green C2 RED R3 green
M3 delete `rng = seed_from_u64` A green B green C1 RED C2 RED R3 green
M4 delete all three A green B green C1 RED C2 RED R3 green
whole revert (M1+M2) A RED B RED C1 green C2 RED R3 RED
M1 and the whole revert fail with `HighWaterRegression { current: 291,
requested: 0 }` — 291 the planted saved position, 0 the fresh stream's word. M2
breaks only the round-trip carrier: the restored stream is `ORIGINAL_SEED`-derived
rather than the worker's.
Deferred and disclosed rather than claimed: the three-statement reseed is now
spelled out at all three resume-class sites — `resume_multiplayer_host_state`
and this one in `engine-wasm`, `GameSession::from_persisted` in `server-core` —
with no shared helper. A `GameState` method would unify them, but
`crates/engine/src/types/game_state.rs` is outside this commit's frozen scope.
Two further sites are deliberately NOT in that class: `rehydrate_rng` (restores a
persisted position rather than starting a fresh stream) and
`filter_state_for_viewer` (produces a view, never a resumable state).

…ound while recording its proposer's own period
`reject_zero_bound_shortcut_offer` accepted a wire state carrying
`schema.is_bounded()` together with a `last_loop_action_sequence` controlled by
the offer's own proposer. No producer mints that pair:
- the object-growth mint (`reconcile_terminal_result`) and the Path A drain mint
(`interactive_loop_bridge`) both publish `MAX_SHORTCUT_CYCLES`, so neither is
ever `is_bounded()`;
- the bounded mint (`certified_bounded_cycle_offer`) is bounded by construction
via its closed-range refusal, but gate (1b) in `bounded_cycle_offer` refuses it
outright while the proposer's own driving period is accumulating.
Accepting the pair is not inert. A declare passes, and accept routes through
`materialize_fixed_shortcut` to the SITE C early return into the object-growth
materializer -- committing *zero* of the agreed cycles while the CR 732.2b
response window is spent. The engine names that misroute in two places already.
The guard is seat-relative (`== Some(*proposer)`), never a global rescan, and it
is deliberately NOT keyed on `per_cycle`: omitting `max_iterations` defaults to
1000, i.e. unbounded, and unbounded-plus-own-period is the *legitimate*
object-growth shape -- so evading this conjunct dissolves the harm instead of
hiding it.
No CR annotation, deliberately. CR 732.2a's Example is itself a bounded
("999,999 more times") own-period proposal, so the rejected class is CR-LEGAL;
this enforces an engine reachability invariant, not a rule. Annotating it would
misattribute a rules licence to a producer-reachability fact. The shipped
comment carries that argument so the absence defends itself.
Test: `a_wire_bounded_offer_carrying_the_proposers_own_period_fails_the_load`,
6 arms over two real captures, no new fixture or helper. Four measured revert
probes, three single-conjunct reverts producing three distinct first-failing
arms plus an ordering probe:
delete the block -> A1 fails (bounded + own period must not load)
delete `is_bounded() &&` -> A3 fails (own period alone stays legal)
delete the period conjunct-> A2 fails (a narrowed bound alone stays legal)
hoist above the zero block-> A6 fails (the zero-bound guard answers first)
Residual disclosed in-code: `RespondToShortcut` carries the same live harm and
is not covered -- `ShortcutProposal` has no `schema`/`max_iterations`, so no
bound-keyed conjunct can see it. Filed, not silently omitted.

…esh measurement
`game_state_size.rs` asserts a compile-time stack budget for `GameState` because
`phase-server` moves it by value through the action + AI path, where an overrun is an
uncatchable guard-page abort rather than a catchable panic. The recorded measurement had
gone stale, leaving the ceiling calibrated to a size the type no longer has.
Re-measured at `a1bfc88d8`:
RUSTFLAGS="-Zprint-type-sizes" cargo build -p phase-engine --lib
types::game_state::GameState: 12784 bytes, alignment: 16
types::game_state::WaitingFor: 1696 bytes, alignment: 8
toolchain `nightly-2026-04-19` (rustc 1.97.0-nightly), host `x86_64-unknown-linux-gnu`,
isolated target dir. The module's own formula — `measured.next_multiple_of(256) + 256`,
one full bucket of deliberate slack — gives `12,784 → 12,800 → 13,056`, so the ceiling
moves 12,800 → 13,056 and the table row records 12,784.
This is the file's documented maintenance branch, not its forbidden one. The assert bans
widening "to make a build pass"; the build passes at either ceiling, so nothing here is
bought by the change. What it buys is the slack the module says the ceiling exists to
carry: at 12,800 the next author to add any inline field to `GameState` would trip a gate
with no context for it, which the module's docs name as the failure this calibration is
meant to prevent.
The stale row is PRE-EXISTING, not introduced here. Measured on plain `main` (55eb20b),
same instrument and same platform: `GameState` is 12,784 there too, identical to this
branch, so no commit in this series contributes a byte. The cause of the gap is NOT
established and is deliberately not claimed: the prior row was taken on
aarch64-apple-darwin and this one on x86_64-unknown-linux-gnu, and that difference alone
could account for it. The platform line now states which row was measured where rather
than implying one platform for all four; the other three rows are carried forward
unchanged and un-re-measured.
Also fixes the reproduce command the module prescribes for exactly this maintenance. It
read `cargo build -p engine --lib`, which cannot work: the package is `phase-engine`
(`crates/engine/Cargo.toml:2`) and `engine` (`:12`) is only the lib target name, so the
command errors with `package ID specification 'engine' did not match any packages`. A
maintenance procedure that cannot be executed as written is a plausible mechanism for a
measurement going stale unnoticed, though this commit does not claim to have established
that as the cause.

…n be declared
A bounded loop-shortcut offer publishes a `MayChoice` decision point for every open
CR 603.5 "may" in the cycle, and declaring the shortcut requires an answer for each one.
Those answers were never recorded: the ring that samples the loop is cleared before the
declare handler runs, so a declare-time recompute returns `None` on every board. This adds
the journal the declaration will be built from; the builder itself ships with the field it
writes into, in the following commit.
The journal is keyed by `(DecisionSource, PlayerId)` and holds `Uniform { take }` until a
second, differing answer for the same pair latches it to `Conflicted` — permanently, within
the window. Recording happens at the `DecideOptionalEffect` reducer beat, before
`handle_optional_effect_choice` resolves the ability, because the key reads the source
object's incarnation (CR 400.7) and resolution can move or destroy that object.
On the seat component of the key, stated so it is not over-read: this is DEFENSE IN DEPTH
PLUS A CODE DELETION, NOT A LIVE-BUG FIX. It replaces a runtime `player == proposer` guard
that was vacuous where it was testable — the publisher filters on `prompt_player ==
proposer` before any point is published, so the guard was never consulted — and harmful
where it was reachable, latching `Conflicted` on a board whose proposer answered
identically every time. No board has been measured on which the seat component changes an
offer; the one multi-seat board that exists journals two seats and mints no offer at all.
The claim this key earns is "cannot be worse, and removes a runtime guard".
Storage follows the ring it derives from: `#[serde(skip, default)]`, excluded from
`impl PartialEq for GameState`, and cleared at all eight ring-clear sites on the same
receiver — three of which are `clone`/`self` rather than `state`. It is boxed because
`GameState` is moved by value through the server action path and carries a compile-time
stack budget; the box keeps the field at 8 bytes.
Evidence. Every claim below was mutated and re-run, not predicted. Collapsing the key to a
bare source reds the two-seat row; deleting the conflict arm reds the latch row while its
idempotence sibling stays green; inverting that arm's inequality guard reds the sibling
while the latch row stays green; dropping the clear in `normalize_for_loop` reds the
follows-the-ring row; neutralizing the write site reds all six journal rows at once, which
is the direct proof that none of them passes on an empty journal. Each journal row asserts
population before it asserts content, because the detection mode defaults to `Off` and an
unpopulated journal would otherwise satisfy every negative assertion trivially.
Also corrects `LoopCertificate.mandatory`'s documentation, which described the field as
recording whether the cycle contained an optional choice. It records the producer's own
measurement that no living player can be forced not to continue (CR 732.5), which is a
different proposition: the tracked four-player board is `mandatory = true` with two
published `MayChoice` points. `detect_loop`'s parameter doc restated the same error and is
corrected with it.
The `game_state_size.rs` measurement row moves 12,784 -> 12,800 for the field this commit
adds. The ceiling is untouched: 13,056 is the formula's answer at both measurements.
DISCLOSED, NOT CLOSED: ring-clear sites 1-4 and 8 have no driven fixture on the boards this
commit uses; they are covered structurally by a source census that fails if any clear site
lacks its journal pair, and the row says so rather than implying driven coverage.
`loop_answer` returns `None` both for "never answered" and for "no journal", so the
consumer in the next commit must treat `None` and `Conflicted` identically; the accessor
documents this, but nothing enforces it until that exhaustive match exists.

Changes requested for current head 67f0412f5c9738fcfc72f229e8e8dccfc169d2df.
exactly_two_waiting_for_variants_carry_a_decision_template_and_both_are_redacted pins the exhaustive WaitingFor census to 129, but the fork point, current base, and this head all contain 130 variants. That stale reach-guard is the CI failure. Update the literal to the current 130-variant contract while retaining the existing syn-based exhaustive check, so later additions and removals remain visible.
…s new variant Upstream phase-rs#7382 added `WaitingFor::EntryControllerChoice { player, candidates }` (CR 614.12a), so the variant reach-guard moves 129 -> 130. Adjudicated on the terms this row already set for phase-rs#7336, not bumped: that variant's body holds no `DecisionTemplate`, so it is not a third carrier, and both the carrier vec and the redaction loop below it are unchanged. Only the reach-guard total moves. The number is read from this assertion's own failure output rather than from a hand-written variant counter -- one was tried and returned 49 while contradicting itself, and a second instrument that disagrees with the syn parse is worth less than no second instrument. This drift produced no merge conflict and could not have, so the reach-guard plus CI were the only things between it and shipping. Assisted-by: ClaudeCode:claude-opus-5

Approved — the exact current head clears the prior blockers and required gates.
✅ Clean
- Required Rust and frontend checks are green on
beff50c2d22c1416d1089afd7b12d8448bbbce76; the current-head parse artifact reports no card-parse changes. - The post-review census correction retains the
synreach guard at 130.WaitingFor::EntryControllerChoicehas onlyplayerandcandidates(crates/engine/src/types/game_state.rs:10260-10263), so it is not a thirdDecisionTemplatecarrier. - The replacement-offer regression is exact:
LoopShortcutModal.tsx:162-169keys the stateful offer by the engine-issued interaction ID, and the tworerendertests cover both changed and byte-identical windows. - The two open CodeRabbit threads are resolved in the current diff: the ring-clear census now walks the full engine source tree (
fantastic_four_bounded_loop.rs:2637), and its requested Polish plural keys conflict with the repository's deliberate exact cross-locale key-parity contract (client/src/i18n/resources.test.ts:73-94). The minimal parity fix is included in this head.
Recommendation: enqueue through the merge queue.

Summary
Makes a bounded loop shortcut publish and validate its own declaration: the engine now journals CR 603.5 "may" answers and CR 608.2b target answers so a shortcut can be declared rather than inferred, publishes the declared count on the offer, and validates it through a single authority. Also fixes three RNG-restore defects on the resume path (native chokepoint, server session restore, engine-wasm worker identity triple), and replaces the offer-writer census's hand-maintained header with a
probe-pinmanifest so it is regenerated from measurement instead of transcribed by hand.Files changed

The module restored a planted state through the#[wasm_bindgen]shell, whose error path builds aJsValue; off wasm32 that panics inside a non-unwinding function, so a returned error became a process abort. Fixed by splittingrestore_game_state_inner(&str) -> Result<(), String>— the shaperesolve_all_inner/scored_candidates_inneralready use — and pointing the test at the inner.

None.
Parser sources are unchanged by this branch (
git diff --name-only <base>..HEAD -- crates/engine/src/parser/is empty), so no card's parse can move. Thecrates/engine/src/parser/paths visible in a diff against currentupstream/mainbelong to upstream commits landed after this branch's base, not to this PR.Scope Expansion
Two corrections outside the loop-shortcut feature, both surfaced by this PR's own verification and both fixing figures that were already wrong on
main:crates/engine/src/types/game_state_size.rs— a mis-calibrated stack-budget ceiling (see Final review-impl).crates/engine-inventory-gen/src/main.rs— stale enum counts in a generator's doc comment.They are included rather than deferred because both are single-number corrections to claims this PR's verification proved false, and leaving a knowingly-wrong measured figure in place to keep a diff narrow is the tech-debt IOU the contributing guide forbids.
Validation Failures
None outstanding. Recorded for honesty, since both were live during this PR's development and were caught by verification rather than review:
probe-pin check, Tiltfile parse, a filtered nextest). Two pinned census tests were failing. Narrow gates prove narrow things and do not compose into "tests pass."engine-wasmentirely — the HIGH above. The gate is now the venue's own command.CI Failures
None known. CI has not yet run against this head.

crates/engine/src/game/engine.rsand all on the same pinned census coordinate. Eight were resolved by locating the producer line by content digest (sha256 8a544e87…5cc7d63, unique under a whole-file scan) rather than by arithmetic, with the offset frombegin_pending_trigger_target_selectionasserted as a control — it held at 134 on every one. The ninth was a deletion the lane intends.One extra commit was then needed, and it is the reason this note is here rather than a line in the log: after a clean replay with no remaining conflict, the pinned coordinate was still wrong. Upstream #4155 inserts five net lines above that producer, so
:12712had become:12717silently. A clean rebase is not evidence that a coordinate survived it — which is the whole reason this row is pinned by digest and re-measured rather than trusted.Verification above was measured at
5ae4379e3. The rebase carries the same trees for the three FU-3 paths; CI is the venue for the re-run at this head.Summary by CodeRabbit
