Wires the gateway's signed SubscribeEvents stream end-to-end:
- backend: emit game.turn.ready from lobby.OnRuntimeSnapshot on every
current_turn advance, addressed to every active membership, push-only
channel, idempotency key turn-ready:<game_id>:<turn>;
- ui: single EventStream singleton replaces revocation-watcher.ts and
carries both per-event dispatch and revocation detection; toast
primitive (store + host) lives in lib/; GameStateStore gains
pendingTurn/markPendingTurn/advanceToPending and a persisted
lastViewedTurn so a return after multiple turns surfaces the same
"view now" affordance as a live push event;
- mandatory event-signature verification through ui/core
(verifyPayloadHash + verifyEvent), full-jitter exponential backoff
1s -> 30s on transient failure, signOut("revoked") on
Unauthenticated or clean end-of-stream;
- catalog and migration accept the new kind; tests cover producer
(testcontainers + capturing publisher), consumer (Vitest event
stream, toast, game-state extensions), and a Playwright e2e
delivering a signed frame to the live UI.
