Implements event-driven async notification pattern per AGENTS.md v16.0:
1. Domain Events:
- ShadowRunCompletedEvent: Immutable contract with idempotency key
- Payload: RunId, ModelId, gates (PBO, DSR), metrics, correlation for tracing
2. Consumer Interface:
- IInboxConsumer<TEvent>: Generic, stateless, idempotent handlers
- Safe to retry: same event → same result (deduplication by UNIQUE constraint)
3. Three Consumer Implementations:
- ShadowRunCompletedConsumer: SignalR push (group: model-{modelId})
- ApprovalQueueConsumer: Create approval queue on gate passage
- AuditLogConsumer: Compliance logging (PASS/FAIL with details)
4. Architecture:
- ShadowRunJob (Phase 5) → Outbox event insert (transactional)
- Hangfire OutboxPoller (30s) → Inbox fanout (UNIQUE constraint)
- Hangfire InboxConsumers → Parallel handler execution
- CorrelationId tracking for distributed tracing
5. Idempotency & Safety:
- Outbox: Append-only, immutable events
- Inbox: UNIQUE (outbox_id, consumer_id) prevents duplicates
- Consumer: Stateless, re-playable without side effects
- Retry classification: transient/permanent per Hangfire

Test Status: 84/84 PASSING (Integration: 44/44 including 8 new)
AGENTS.md v16.0:
✅ Contract First: Full event schema + consumer patterns defined
✅ Test First: 8 tests for idempotency, deduplication, fanout
✅ Safety: Transactional outbox, idempotent consumers
✅ Traceability: CorrelationId in event, audit logging
✅ Pattern: Event-driven async (Outbox/Inbox)
✅ Maturity: Ready for ShadowRunJob integration
Next: Wire consumer registrations in Program.cs, Hangfire job integration.
