Gate 5: Observability & Alerting (Metrics & Dashboard Foundation)
Implements validation gate 5: Production readiness observability infrastructure Backend implementation: 1. IObservabilityService interface - 5 metric families 2. ObservabilityService implementation - SQL queries for metrics 3. GetObservabilityMetrics endpoint (GET /api/v1/observability/metrics) Metric Families (Grafana/Seq integration-ready): 1. **Batch SLA Metrics**: Job completion times, queue depths, retry rates - QueueDepth: Pending job count - AverageCompletionTimeMs: Job execution time - TotalJobsCompleted: Success count - RetryCount: Retry rate tracking 2. **Data Quality Metrics**: Quarantine monitoring - QuarantinedJobCount: Jobs marked dq (data quality) - TopQuarantineReasons: Error pattern analysis - AverageQuarantineAgeHours: Quarantine age tracking 3. **Duplicate Detection**: Constraint violation monitoring - DuplicateViolationCount: Inbox dedup failures - AffectedMessageCount: Impact analysis - LastViolationAt: Recency tracking 4. **Reconciliation Metrics**: Audit trail completeness - OutboxMessageCount: Total published events - InboxProcessedCount: Processed events - AuditTrailCompleteness %: Evidence preservation ratio - MismatchCount: Orphaned messages 5. **Model Drift Metrics**: OOS performance tracking - ModelsUnderMonitoring: Active model count - AverageOosPerformance: Out-of-sample DSR - PerformanceDegradedCount: Alert threshold - BaselineSharpeRatio: Baseline comparison Alert Thresholds (AGENTS.md v16.0 constraint enforcement): - CRITICAL: Duplicate inbox messages detected - WARNING: Audit trail completeness < 95% - WARNING: > 10 jobs in quarantine - WARNING: Model performance degradation detected Test coverage (6 scenarios): 1. Batch SLA metrics structure validation 2. Data Quality quarantine monitoring 3. Duplicate detection identification 4. Reconciliation completeness calculation 5. Model drift OOS tracking 6. Alert threshold conditions Architecture: - Database queries (Hangfire + audit tables) - Metrics DTOs for serialization - REST endpoint for dashboard consumption - Ready for Grafana/Seq/OpenTelemetry integration AGENTS.md v16.0 compliance: ✓ Evidence-based monitoring (5 metric families) ✓ Constraint validation (alert thresholds) ✓ Audit trail traceability (correlation IDs) ✓ Complete endpoint (all gates monitored) Build: Clean, 0 errors Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>
