Tasks: events-spec-tightening

1. Spec delta

• 1.1 Author specs/events/spec.md delta with ## MODIFIED Requirements (Deterministic id and clock sources, Structured errors, Passive observability adapter) and ## ADDED Requirements (emitAsync timeout, emitAsync abort, Envelope traceId propagation).
• 1.2 Add **Verified by:** line to every requirement (existing + new).

2. Conformance test

• 2.1 Add packages/events/events/src/conformance.spec-conformance.test.ts pinning:
  • new EventBus({ clock, idGenerator }) accepts injections (replaces ghost createBus).
  • Async listener throw is captured into EmitResult.errors with EVENTS.LISTENER.THREW.
  • withObservability adapter onEmitError fires when dispatch rejects.
  • emitAsync with timeoutMs rejects with EVENTS.EMIT.TIMED_OUT past the deadline.
  • emitAsync with an aborted AbortSignal rejects with EVENTS.EMIT.ABORTED (cause === signal.reason).
  • traceId passed to emit / emitAsync surfaces on EventEnvelope.traceId.

3. Gate

• 3.1 bunx turbo lint typecheck test --filter=@suaveplan/events green.
• 3.2 bunx turbo test:coverage --filter=@suaveplan/events 100/100/100/100.
• 3.3 bun scripts/openspec-conformance.ts @suaveplan/events exits 0.

4. Fold + archive

• 4.1 Fold delta into openspec/specs/events/spec.md.
• 4.2 Move openspec/changes/events-spec-tightening/ to openspec/archive/2026-04-27-events-spec-tightening/.
