Reliability & Service Level Objectives (SLOs)

Availability Objective: 99.9% uptime for core API endpoints (/health, /api/v1/items, /api/v1/auth).
Latency Objective (p95): < 250ms response time under peak load.
Error Rate Objective: Server error rate (5xx) < 0.1% over a 5-minute rolling window.
Mean Time to Detection (MTTD): < 60 seconds via Prometheus alert rules.
Mean Time to Resolution (MTTR): < 5 minutes via automated root-cause isolation and test-gated hotfix deployment.
