…tellaBridge#1089 StellaBridge#1090 StellaBridge#1091) ## Summary Implement comprehensive backend infrastructure for four major monitoring capabilities: ### Issue StellaBridge#1093: Alert Noise Reduction Recommendations - Analyze alert firing patterns and false positive rates - Generate actionable recommendations to reduce alert fatigue - Support threshold adjustments, alert suppression, and correlation filtering - Track recommendation status and application metrics ### Issue StellaBridge#1089: Soroban Invocation Cost Trends - Record Soroban contract invocation costs with CPU, memory, and network metrics - Compute cost trends across multiple granularities (hourly/daily/weekly/monthly) - Detect cost anomalies with configurable baselines and deviation thresholds - Provide historical cost analysis and p-percentile tracking ### Issue StellaBridge#1090: Ledger Close Delay Alerts - Monitor Stellar ledger closure timing and identify delays - Create alerts for delays exceeding configurable thresholds - Compute delay statistics and detect recurring patterns - Support pattern analysis for time-of-day and burst detection ### Issue StellaBridge#1091: Horizon Cursor Audit History - Maintain comprehensive audit trail for cursor position changes - Track cursor advances, resets, and rollbacks with full provenance - Support cursor reconciliation between local state and Horizon - Implement rollback workflows with severity classification and reprocessing flags ## Implementation Details **Database Migrations:** - 055_alert_noise_reduction.ts: Analysis results and recommendations - 056_soroban_invocation_cost_trends.ts: Invocation costs, trends, and anomalies - 057_ledger_close_delay_alerts.ts: Closure events, alerts, and pattern detection - 058_horizon_cursor_audit_history.ts: Cursor positions, audit logs, rollbacks, and reconciliations **Services:** - alertNoiseReduction.service.ts: Analysis engine with recommendation generation - sorobanInvocationCost.service.ts: Cost tracking and trend computation - ledgerCloseDelay.service.ts: Delay monitoring and pattern detection - horizonCursorAudit.service.ts: Cursor state management and audit trail **API Routes:** - alertNoiseReduction.routes.ts: Analysis CRUD and recommendation lifecycle - sorobanInvocationCost.routes.ts: Invocation recording and trend queries - ledgerCloseDelay.routes.ts: Event recording and statistics computation - horizonCursorAudit.routes.ts: Cursor operations and reconciliation workflows **Route Groups:** - Updated alert-routes.ts to register noise reduction endpoints - Updated analytics-routes.ts to register Soroban cost tracking endpoints - Created operational-monitoring-routes.ts for ledger and cursor endpoints - Registered operational-monitoring-routes in main routes index ## Acceptance Criteria Met ✓ Documented API and persistence contracts with schemas ✓ Failure, retry, authorization, and observability behavior covered ✓ Existing consumers remain compatible with new optional endpoints ✓ Service boundaries follow established patterns (database, service, routes) ✓ Operational documentation via schema definitions and error handling Closes StellaBridge#1093, Closes StellaBridge#1089, Closes StellaBridge#1090, Closes StellaBridge#1091.
