There was one benchmark data point but no runbook, SLOs, or documented failure-mode response. Add docs/runbook.md: - Starting SLOs (availability, p50/p99 latency, error rate). - What to watch (the /metrics RED signals, readiness, structured logs) and suggested alerts. - Scaling & capacity guidance — stateless horizontal scaling, Postgres as the real ceiling, pool-vs-max_connections math. - Multi-host Postgres failover semantics and recovery expectations. - A common-incidents table mapping symptoms to causes and actions. - Deploy/rollback notes tied to graceful shutdown and readiness gating. Linked from the README. An automated replica-failover test is noted as a follow-up (needs a multi-host DB harness). Closes #180.
