Implements shared engine-side stack-resolution sessions: Resolve All consent extends the same session machinery, verified AI priority passes recheck live meaningful actions, and restored game states explicitly resume engine-side automation. Retires browser-owned Resolve All transport.

Summary by CodeRabbit

  • New Features

    • Restored games now automatically resume pending stack actions and show a concise result summary.
    • Multiplayer hosts finish restoration before accepting reconnecting players.
    • Stack resolution now follows a unified engine-managed flow for consent, auto-pass, and AI actions.
    • Replay playback preserves verified AI priority actions.
  • Bug Fixes

    • Improved recovery for interrupted games, terminal states, and failed saves.
    • Prevented private stack-resolution details from appearing in game views.
  • UI Updates

    • Replaced live progress indicators with a dismissible restored-automation summary.

📝 Walkthrough

Walkthrough

This PR moves Resolve All and restored stack automation into engine-owned, fenced sessions. It adds explicit restore APIs, strict persistence barriers, terminal handling, verified AI recheck passes, private session redaction, and client presentation state. It removes the previous browser and WebSocket Resolve All transport.

Changes

Stack automation and restore flow

Layer / File(s) Summary
Session contracts and persisted state
crates/engine/src/types/..., crates/engine/src/game/visibility.rs, crates/engine/src/game/derived_views.rs, crates/engine/src/types/replay.rs
Persisted state now includes stack-resolution budgets, policies, entry fences, overlays, sessions, and typed replay markers. Client projections redact private session data.
Shared session runner and consent lifecycle
crates/engine/src/game/engine.rs, crates/engine/src/game/engine_resolve_batch.rs, crates/engine/src/game/priority.rs, crates/engine/src/game/elimination.rs
Resolve All consent and UntilStackEmpty auto-pass use fenced sessions with representative validation, budget tracking, baseline restoration, and topology cleanup.
Verified AI priority-pass flow
crates/phase-ai/src/auto_play.rs, crates/engine/src/game/replay.rs, crates/engine-wasm/src/lib.rs
AI passes on non-empty stacks use a verified engine seam. Replay records and replays the semantic owner and policy.
WASM, server, and adapter resume wiring
crates/engine-wasm/src/lib.rs, crates/server-core/src/session.rs, crates/phase-server/src/main.rs, client/src/adapter/*
Restore operations return automation presentations and snapshots. P2P hosts persist resumed authority before reconnects, commit terminal results before clearing durable state, and abort unpublished resumes on failure.
Client state and presentation flow
client/src/stores/gameStore.ts, client/src/game/dispatch.ts, client/src/components/board/*, client/src/components/modal/ResolveAllConsentModal.tsx
The client dispatches one engine-owned BeginResolveAll action, consumes one-shot restored automation results, clears them after state changes, and renders localized summaries instead of live progress.
Persistence and integration validation
client/src/services/*, client/src/adapter/__tests__/*, crates/engine/tests/integration/*, crates/phase-server/src/main.rs
Tests cover strict persistence, restore classification and repair, session fencing, terminal startup, reconnect barriers, private-state redaction, and removal of Resolve All transport paths.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟡 Moderate · up to ecee9

This PR moves Resolve All and restore/resume into persisted engine sessions while changing auto-pass cancellation and protocol behavior. The current head still risks failed validation, unintended automatic passes, stale-client deserialization failures, stalled restored games, and duplicate concurrent automation, so these concrete issues should be fixed or explicitly accepted before merge.

The stack-recheck routing predicate is duplicated across two crates. Both call sites re-derive when a PassPriority must go through apply_verified_ai_priority_pass instead of the ordinary interaction path, and both drop their local contract.permits gate based on that local derivation. One engine-owned predicate next to the seam prevents the two transports from drifting apart.

Extract the shared terminal-state predicate.

Lines 186-191 duplicate the terminal test from saveGame (lines 160-163) verbatim. The two functions must agree on what "terminal" means: saveGame skips the write, and saveResumableGameStrict refuses it. If the definition later gains a match_phase value or a terminal waiting_for variant, one site can drift and retain a completed game as resumable.

Consider clearing restoredStackAutomation inside commitEngineSnapshot instead of at each call site.

Four commit sites in this file (Lines 571, 803, 889, 970) plus dispatch and undo in client/src/stores/gameStore.ts repeat restoredStackAutomation: null. The invariant is "any accepted live-game commit ends the one-shot restore summary". A future commit site that omits the field will leave the restored-automation overlay on screen after the game advanced.

Move the clear into commitEngineSnapshot as the default for accepted pairs, and let the two resume sites seed the presentation through extraState (applied last, so it still wins).

The negated policy check fails open for future engine-internal policies.

isResolvingStack treats every UntilStackEmpty policy except RecheckNoMeaningfulPriorityAction as human-owned. If the engine adds another internal policy variant, this component renders the "Resolving Stack..." cancel control for it and lets the player dispatch CancelAutoPass against an engine-internal session.

Prefer a positive test over the policy union, so a new variant must be classified explicitly. An exhaustive switch on autoPass.policy (or an engine-authored ownership field on the auto-pass mode) makes the compiler flag the new case instead of silently exposing it in the UI.

As per path instructions for crates/**/*.rs and the repo pillars, prefer "exhaustive match over wildcard fallbacks"; the same reasoning applies to this discriminant test on the client.

7650-7661: 🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick win

Evaluate priority_player_has_meaningful_action only when a branch can use its result.

priority_player_has_meaningful_action clones the whole GameState and runs flush_layers plus legal-action enumeration. This seam now runs on every automatic priority beat while a session is live, including the common case where the result is discarded.

Both arms that read the probe require StackResolutionSessionPassKind::Automatic. The second arm additionally requires that the holder is not a session representative. So for a Committed session driven by its own representative — the ordinary Resolve All path — the probe runs once per resolved entry and its answer is never used. On a deep stack this adds one full state clone and one action enumeration per entry per beat.

Move the cheap predicates in front of the probe. The conditions are pure conjunctions, so the reorder does not change the decision.

- Around line 360-373: Wrap the ResolvedAbility::new call assigned to
StackEntryKind::ActivatedAbility::ability in Box::new so the fixture provides
the required Box<ResolvedAbility> type.

In `@crates/engine/tests/integration/resolve_all_consent.rs`:
- Around line 551-559: Convert state.auto_pass and the corresponding
StackResolutionAutoPassOverlay::baseline value from HashMap<PlayerId,

construction sites, preserving all entries and satisfying auto_pass_baseline’s
expected type.

- Around line 1449-1459: Add an explicit collection type annotation to
reconnect_players in the session player-token iteration, using the collection
type required by its later for-loop consumption. Preserve the existing filtering
of non-empty, non-AI player tokens.
- Around line 2164-2210: Update the restored_full_startup_tests module to import
GameSession from server_core::session and replace all three

Outside diff comments:
In `@crates/engine-wasm/src/lib.rs`:
- Around line 2296-2334: Update the engine recovery flow in engineRecovery.ts
after restoring the snapshot to call adapter.resumeRestoredGameState(), publish
the returned state through the existing snapshot update path, and only report
recovery success after resumption completes. Preserve the existing restore error
handling and ensure restored StackResolutionSession or ResolveAllReady states
are resumed before callers continue.

In `@crates/engine/src/game/stack.rs`:
- Around line 7474-7479: Import
resolve_proven_inert_trigger_batch_with_proof_hook into the batch_resolve
module’s explicit super::super import list so the bare call in the test resolves
without changing surrounding test behavior.

In `@crates/server-core/src/protocol.rs`:
- Around line 2425-2427: Update PROTOCOL_VERSION to a new value for the breaking
wire-format change, and update protocol_version_is_42 to assert the new value so
stale v42 clients cannot complete the handshake.

Nitpick comments:
In `@client/src/components/board/ActionButton.tsx`:
- Around line 274-278: Update the isResolvingStack policy classification to
positively identify the human-owned UntilStackEmpty policy instead of excluding
RecheckNoMeaningfulPriorityAction. Use an exhaustive autoPass.policy switch or
equivalent discriminant-based logic so newly added engine-internal policies
cannot expose the resolving-stack cancel control without explicit
classification.

In `@client/src/game/controllers/aiController.ts`:
- Around line 437-445: Merge the two adjacent waitingForChanged ||
sessionChanged blocks into one block containing invalidateAttempt,
lastWaitingForKey reset, and checkAndSchedule. Update the stale comment near
isAttemptCurrent to describe only the checks that function currently enforces,
removing the obsolete Resolve All ownership invariant.

In `@client/src/game/dispatch.ts`:
- Around line 886-890: Move the default clearing of restoredStackAutomation into
commitEngineSnapshot for every accepted live-game commit, removing repeated
restoredStackAutomation: null values from its call sites, including dispatch and
undo. Preserve the two resume flows’ explicit extraState values and ensure they
are applied last so their presentation state overrides the default.

In `@client/src/services/gamePersistence.ts`:
- Around line 181-193: Extract the duplicated terminal-state check into a shared
predicate near saveGame and saveResumableGameStrict, then route both functions
through it. Preserve the existing behavior: saveGame skips terminal states,
while saveResumableGameStrict throws before writing them.

In `@crates/engine/src/game/engine.rs`:
- Around line 7650-7661: Reorder the logic around
priority_player_has_meaningful_action so the cheap pass-kind and
session-policy/representative predicates are evaluated before invoking the
probe. Ensure priority_player_has_meaningful_action runs only when either
PauseRetained or Pause can use its result, while preserving both existing
decision outcomes.

In `@crates/phase-ai/src/auto_play.rs`:
- Around line 302-307: Introduce or reuse one engine-owned predicate for
determining whether a PassPriority action is a stack recheck, then use it at
both call sites: replace the local derivation in
crates/phase-ai/src/auto_play.rs lines 302-307 while preserving
apply_verified_ai_priority_pass versus apply_interaction routing, and replace
the duplicated matches!/stack check in crates/engine-wasm/src/lib.rs lines
3140-3161 with the same predicate. Keep the existing contract.permits behavior
aligned with this shared result.

In `@crates/phase-server/src/main.rs`:
- Line 4813: Remove the disabled Resolve All remnants: delete handle_resolve_all

8719-8739: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Fix the key mismatch in CancelAutoPass's fallback branch: use the representative, not the raw actor.

The fallback branch removes entries by actor instead of by representative, but every other place in this file that reads or writes state.auto_pass or session.auto_pass_overlay.baseline uses the canonical priority representative as the key.

Two same-file examples confirm the required key:

  • store_direct_auto_pass_request computes representative and inserts the baseline entry as baseline.insert(representative, updated_mode).
  • The deliberate-action cancellation block computes session_preference_owner via priority_pass_representative and uses it for both state.auto_pass.remove(...) and session.auto_pass_overlay.baseline.remove(...).

The comment directly above line 8738 states the exact requirement this branch violates: "Cancelling it must remove the same saved key, or later teardown would resurrect a preference the player explicitly withdrew." When actor != representative (shared team turns, e.g. Two-Headed Giant — a format this same PR adds tests for — or under turn-control effects), state.auto_pass.remove(&actor) and session.auto_pass_overlay.baseline.remove(&actor) target the wrong key. The auto-pass entry keyed by representative is never removed, so:

  1. The cancellation silently fails to stop the standing auto-pass for that representative.
  2. When the session later tears down via take_and_restore_stack_resolution_session, it restores state.auto_pass from session.auto_pass_overlay.baseline, resurrecting the exact preference the player explicitly cancelled.

This can cause a player to keep auto-passing priority against their explicit choice, potentially missing a window to respond to a threat.

🐛 Proposed fix
         } else {
-            state.auto_pass.remove(&actor);
+            state.auto_pass.remove(&representative);
             if let Some(session) = state.stack_resolution_session.as_mut() {
                 // A nonrepresentative preference can be merged into the
                 // pre-overlay baseline while a session is live. Cancelling it
                 // must remove the same saved key, or later teardown would
                 // resurrect a preference the player explicitly withdrew.
-                session.auto_pass_overlay.baseline.remove(&actor);
+                session.auto_pass_overlay.baseline.remove(&representative);

3955-3968: 🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick win

Avoid cloning the whole remaining stack before filtering.

inert_noop_run_len clones every remaining StackEntry up front with state.stack.iter().rev().cloned().collect::<Vec<_>>(), then applies take_while. The clone happens unconditionally, even when the first entry already fails stack_entry_is_inert_noop and the whole clone was unnecessary. resolve_next_with_limit calls this on every resolution step, so a large stack with a short inert prefix pays a full-stack clone on each step.

batch_run_len in this same file avoids this by walking state.stack.iter().rev().skip(1) directly with an early break, never materializing the whole im::Vector into a Vec. Apply the same incremental pattern here: fetch one entry at a time by index and stop at the first entry that fails the predicate.

As per path instructions, "Hot im::Vector zones must use im methods (push_back/pop_back/iter_mut), not materialize a std Vec."

♻️ Proposed fix
 fn inert_noop_run_len(state: &mut GameState) -> Option<u32> {
     // The classifier can consult mutable choice caches, so do not retain an
     // immutable borrow into `state.stack` while it runs.
-    let entries = state.stack.iter().rev().cloned().collect::<Vec<_>>();
-    let count = entries
-        .iter()
-        // An already-recorded Decline is resolution-inert regardless of the
-        // trigger source or firing event.  The speculative runner still proves
-        // each exact entry and checkpoint before committing the prefix.
-        .take_while(|entry| stack_entry_is_inert_noop(state, entry))
-        .count()
-        .min(u32::MAX as usize) as u32;
+    let len = state.stack.len();
+    let mut count = 0u32;
+    for offset in 0..len {
+        let index = len - 1 - offset;
+        let Some(entry) = state.stack.get(index).cloned() else {
+            break;
+        };
+        // An already-recorded Decline is resolution-inert regardless of the
+        // trigger source or firing event.  The speculative runner still proves
