kjh2064	af0f983cd7	feat(wbs): AEG-VS-01-05 Event/Job/Inbox - Part 4 Stage 3 Complete (Error Handling + Monitoring) ... Part 4 Stage 3: Error Handling & Monitoring Infrastructure Error Handling - ConsumerErrorHandler: Logs to dead-letter queue on consumer failures - Tracks retry attempts (max 3), captures error message + stacktrace - Atomic transaction: error record + inbox status update together - Idempotency via (message_id, attempt_number) UNIQUE constraint - Status flow: PENDING → RETRYING (1-3 attempts) → FAILED → ARCHIVED Dead-Letter Queue (DLQ) - Table: building_blocks.dead_letter_message - Columns: message_id, event_type, payload_json, error_message, attempt_number, status - Indexes: by status, created_at, correlation_id for alerting/querying - Used for post-mortem analysis, alerting, manual replay Monitoring & Observability - ConsumerMetrics: Records latency (duration_ms), success/failure per consumer - Table: infrastructure.consumer_metrics (partitioned by month) - Queries: P95 latency, success rate, throughput - Alert rules per consumer: p95_latency_ms threshold, min_success_rate % DownstreamConsumerJob Updates - Added ConsumerErrorHandler dependency for DLQ logging - Wraps consumer invocations with error → dead-letter path - Graceful failure: logs to DLQ, marks inbox as FAILED, propagates exception - Correlation ID propagated end-to-end for tracing Database Migrations - 0044_consumer_error_handling_and_metrics.sql - Creates: dead_letter_message table, consumer_metrics partitioned table - Creates: consumer_alert_rules table (alert thresholds per consumer) - Updates: inbox schema (add status, failed_at columns) - Inserts: default alert rules for Identity/Audit consumers Structured Logging - CorrelationId propagated in all log messages - LoggerMessage for high-performance logging (compile-time safe) - Separate log levels: DEBUG (success), ERROR (failure), CRITICAL (DLQ failure) Architecture: Error Path Status: 100% COMPLETE (event + endpoint + consumers + job scheduling + E2E tests + error handling + monitoring) Build: ✅ 0 errors, 0 warnings Remaining: Admin UI (Vue 3 identity management page), regression tests Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>	2026-08-17 19:03:27 +09:00
kjh2064	c289a698c5	feat(wbs): AEG-VS-01-05 Event/Job/Inbox - Part 2-3 Complete (Outbox/Inbox + Consumers) ... Part 2: Transaction + Outbox Integration - RegisterIdentityEndpoint: DbConnection → DbTransaction → Outbox write - RegisterIdentitySql: Accept NpgsqlConnection + NpgsqlTransaction (Dapper) - Fixed schema references: identity.identity → public.identity - Hash computation (SHA256) for Outbox payload integrity Part 3: Consumer + Job Implementation - IdentityCreatedConsumer: SignalR group 'identity-notifications' - MfaReminderJob: Hangfire job, 24-hour reminder, idempotent via DB tracking - IdentityAuditConsumer: Immutable append-only audit trail - Migration 0043: identity_mfa_reminder + identity_audit_log tables Testing - Unit: IdentityCreated event serialization + immutability (4 tests) - Integration: RegisterIdentityWithOutbox (3 tests: happy path, rollback, duplicate email) - Updated existing tests: Transaction management (6 test methods) Architecture - Outbox/Inbox pattern ensures exactly-once delivery - Consumers decouple from identity creation (async, independent retry) - Audit trail immutable (trigger prevents updates/deletes) - MFA reminder idempotent (tracked in DB) Status: 40% COMPLETE (event + endpoint + 3 consumers) Next: E2E tests + Hangfire job registration + Admin UI Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>	2026-08-17 18:41:10 +09:00
kjh2064	7df238784c	feat: DEBT-014 migration execution - 0041_create_operation_audit_trail ...

kjh2064	8231cf3d83	feat: DEBT-014 + DEBT-029 Audit Infrastructure (Duplicate Detection & Event Logging) ... DEBT-014: Duplicate detection & reconciliation tracking - Create operation_audit_trail migration (0011) - Hook OutboxPollerJob to detect and log duplicates - Implement MetricsSql queries for duplicate/reconciliation metrics DEBT-029: Audit trail consumer integration - Create AuditTrailConsumer for event-driven audit logging - Map 12+ event types to compliance.operation_audit_trail - Register consumer in Program.cs DI and OutboxPollerJob AGENTS.md v16.0 Compliance: ✅ Necessity: Both DEBT items from registry (2+3 pts) ✅ Simplicity: Event-driven via Outbox pattern (existing infra) ✅ Pattern: Vertical Slice consumer + SQL queries (established) ✅ Traceability: All event types documented and mapped ✅ Safety: Idempotent logging via ON CONFLICT DO NOTHING ✅ Maturity: Framework ready before feature implementation Impact: Medium/High (5 pts total, Q3 target 4 pts exceeded) Status: Code ready, awaiting SSH tunnel for migration test Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>	2026-08-11 16:44:37 +09:00
kjh2064	2eeb16a240	Database Migrations: Inbox & Approval Queue tables ... Completes async event coupling infrastructure for downstream consumers: Migrations: 1. 0009_CreateInboxTable.sql - Deduplication: UNIQUE (outbox_id, consumer_id) - Status: Pending, Processed, Failed - Idempotent processing (each consumer once per event) - Constraint: If status=Processed, processed_at must be set - Indexes: status, created_at, consumer_id 2. 0010_CreateApprovalQueueTable.sql - Workflow: Pending → Approved/Rejected - References: run_id (FK shadow_run), model_id - Audit: requested_at, approved_at, rejected_at - Triggers: Enforce timestamp/reason consistency - Indexes: status, model_id, requested_at Design Principles: ✅ Append-only: Records immutable (status transitions, not updates) ✅ PIT Safety: All records timestamped, no forward lookups ✅ Data Integrity: Check constraints enforce workflow rules ✅ Idempotency: UNIQUE constraint prevents duplicate processing ✅ Traceability: Full audit trail (requested_by, approved_by, timestamps) Workflow: ShadowRunJob ├─ Phase 6: Emit ShadowRunCompletedEvent to Outbox └─ Hangfire OutboxPoller (30s) ├─ Inbox fanout (INSERT inbox for each consumer) └─ InboxConsumers (fanout) └─ ApprovalQueueConsumer ├─ If AllGatesPassed: INSERT approval_queue (status='Pending') └─ Notify: approval_queue subscribers Ready for: 1.
