fix(core): batch stream writes via writeMulti (#2995)

[core] Gate event creation on the loaded event count and restart replays in-process (#3145)

[world] Guard hook_received against a concurrent run termination (#2987)

Add stateUpdatedAt precondition guard to event creation (#2266)

Fix duplicate inline step execution on mid-step wake via message ownership (#2848)

[core] Derive correlation ids from per-kind sequences (opt-in) (#3301)

Fix hook token reuse after dispose() (same-run and cross-run) (#2779)

[world-local] Fix per-step AbortSignal latency and O(world) chunk polling (#2807)

[world-vercel] Switch event endpoints to v4 wire format (#2055)

[e2e] Add `event-log-race-repro` label for triggering CI stress-test (#2159)

Make runtime tuning constants env-configurable; forward server limit-override header (#2718)

perf(core): parallel inline steps + optimistic lazy step start (#2516)

[world-vercel] Unify HTTP request handling into a shared core (#2631)

[core] Turbo mode: fast-path the first invocation (#2526) On the first delivery of a run's first invocation, background run_started, skip the initial event-log load, and force optimistic inline start so the run reaches its first steps with no preceding network round-trips. Safe because the first delivery has no concurrent handler to race the step create-claim; turbo exits the moment a suspension creates a hook or wait, and is a no-op for every other invocation. On by default; disable with WORKFLOW_TURBO=0.
