Sync tools in one assistant batch now run via Promise.all instead of sequentially — a tool pending on I/O no longer blocks its siblings. Three coordinated changes keep the event-sourced runtime sound: - executeAllowedTools is two-phase: invocation events are appended serially in source order (durable before any side effect, deterministic log prefix), then all sync executions run concurrently, each appending progress/results as they land. Per-call error and cancel semantics are unchanged (moved to executeSyncTool). - append() commits through an internal queue: persist → reduce → stream runs to completion per batch, so file order, in-memory order, and stream order stay identical even while executions overlap. A failed commit rejects only its caller; the chain survives for siblings. - Abort-registry state is scoped per tool call (turnId:toolCallId) via a wrapper, fixing two latent races: createForRun destroying a running sibling's tracked processes, and cleanup tearing down the turn-wide force-kill scope when the first tool finished. Wire ordering is untouched: model requests already reference tool results by the assistant message's source order, pinned by a new test. No concurrency cap and no per-tool serialization by design; tools that share state must tolerate racing (file edits already reject stale writes via their search/replace precondition). Spec §4.5/§10.5 updated. New runtime tests cover overlap (deadlock unless concurrent), progress interleaving, sibling failure isolation, mid-batch cancellation, and crash recovery with multiple open invocations.
