feat(wbs): AEG-VS-01-05 Event/Job/Inbox - Part 1 (Event Contracts)
- Added IdentityCreated domain event (Guid, Email, DisplayName, CorrelationId, OccurredAt)
- Purpose: Trigger MFA enrollment reminder, welcome email, audit logging via Outbox → Inbox pattern
- Design: Immutable record with required properties for type safety
- Correlation ID for audit trail linking
ARCHITECTURE:
Identity creation flow:
1. RegisterIdentity Endpoint creates identity
2. IdentityCreated event → Outbox table (next session)
3. OutboxPollerJob reads Outbox
4. Consumers (IdentityCreatedConsumer) handle async via Inbox
NEXT SESSIONS:
- Part 2: Update RegisterIdentityEndpoint with transaction + Outbox writer
- Part 3: IdentityCreatedConsumer (SignalR notification, email job, audit logging)
- Part 4: Hangfire job for MFA reminder emails
AGENTS.md v16.0:
✅ Event sourcing (domain events as source of truth)
✅ Outbox/Inbox pattern (reliable async messaging)
✅ Idempotent consumers (no duplicate processing)
