How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

📝 WalkthroughWalkthroughThe PR adds a consent-based Resolve All protocol. The engine stores epoch-scoped consent state, exposes authorized actions, resolves safe stack prefixes, and integrates the flow with client UI, AI handling, WASM, server execution, interactions, and tests. ChangesResolve All consent protocol
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🔴 Critical · up to This change gates Resolve All behind unanimous consent, but the current implementation can reject valid consent in some participant orders and leave client-, AI-, or multi-player flows unable to complete; it also resets loop and auto-pass state during the handshake. These correctness and availability issues make the PR not merge-ready until fixed. Sequence Diagram(s)sequenceDiagram

In `@client/src/components/modal/ResolveAllConsentModal.tsx`:
- Around line 30-34: Update the Grant branch in the ResolveAllConsentModal
handler to read the atomic useGameStore.getState().waitingFor field when
checking for the ResolveAllReady type, rather than gameState.waiting_for; keep
dispatchResolveAll(playerId, []) unchanged.
In `@client/src/game/controllers/aiController.ts`:
- Around line 394-400: Update the scheduling logic in aiController using an
explicit ResolveAllConsent branch that selects waitingFor.data.representative
instead of relying on authorizedAiPlayer(), then schedule the AI
RespondResolveAllConsent proposal for that representative. Add a regression test
covering an AI representative progressing through ResolveAllReady.
In `@crates/engine/src/game/engine_resolve_batch.rs`:
- Around line 129-133: In the successful teardown path of the resolve-all
consent run, replace the direct assignment to state.resolve_all_consent_run with
turn_control::invalidate_resolve_all_consent(state), preserving the existing
finalize_display_state call and ensuring the helper does not alter the
already-advanced waiting_for state.
- Around line 167-178: Update consent_authorization_matches to compare frozen
and live participants by representative identity rather than positional order,
while still validating each representative’s authorized_submitter and preserving
the length check. Ensure unchanged topology remains valid after
begin_resolve_all_consent rotates run.participants.
- Around line 889-905: Extend
ready_consent_refuses_to_collapse_while_an_auto_pass_preference_is_active with a
positive reach-guard: verify that an otherwise identical ready state with
auto_pass empty successfully resolves before asserting refusal with the active
UntilStackEmpty preference.
Apply the same fix in `@crates/engine/tests/integration/resolve_all_consent.rs`
around lines 116 - 141: The same reach-guard requirement applies to the
hand-built controller transition in the frozen-submitter test.
In `@crates/engine/src/game/engine.rs`:
- Around line 8162-8187: Update the shared prologue exemption checks for
loop-ring/journal clearing and auto-pass clearing to include BeginResolveAll,
RespondResolveAllConsent, and RevokeResolveAllConsent. Preserve existing
exemptions and ensure all Resolve All protocol actions avoid both clears without
changing their dispatch behavior.
In `@crates/engine/src/game/interaction.rs`:
- Around line 439-442: Update classify_waiting_for and related decision handling
so WaitingFor::ResolveAllConsent uses a dedicated SimultaneousDecisionKind
variant, marking the interaction as simultaneous. Ensure
rebind_interaction_slots_after_action preserves IDs for representatives that do
not submit, allowing their existing pending revoke submissions to remain valid.
In `@crates/engine/src/types/game_state.rs`:
- Around line 15179-15182: Update GameState::normalize_for_loop to reset
next_resolve_all_consent_epoch to zero alongside the other monotonic allocator
fields, preserving loop-state equality when only the Resolve All consent epoch
differs between iterations.
In `@crates/server-core/src/session.rs`:
- Around line 1601-1615: The doc comment for resolve_all_for_player still
describes the removed AI-seat authorization model; rewrite it to state that
execution requires an engine-issued unanimous ResolveAllReady consent run, with
AI seats excluded from authorization. Document that max_resolutions is
range-checked for protocol compatibility but does not determine the resolution
cap.

P1: Module-level pendingResolveAllSeats is unprotected mutable shared state that races between async invocations
Module-level let pendingResolveAllSeats is written in one async branch and read later without synchronization.
Store pending seats inside the game store keyed by gameId instead of a module-level global.

<title>Module-level `pendingResolveAllSeats` is unprotected mutable shared state that races between async invocations</title>
<evidence>`let pendingResolveAllSeats: { playerId: number; difficulty: string }[] | null = null;` is declared at module scope. In `dispatchResolveAll`, the non-Ready branch writes `pendingResolveAllSeats = aiSeats;` (line ~1018), awaits an async dispatch, and returns. A later call on the Ready branch reads `const resolvedSeats = pendingResolveAllSeats ?? aiSeats;` (line ~1025). If two calls interleave—e.g., a rapid double-click or an AI proposal racing a human click—the second write overwrites the first before the consent flow reaches Ready, so the wrong seat list is used for resolution.</evidence>
<recommendation>Move `pendingResolveAllSeats` into `gameStore` keyed by `gameId` (or by the current consent `epoch`) so it is scoped to a specific game instance and cannot be overwritten by a second concurrent call.</recommendation>
