Acts on the audit's NEXT block — operational resilience. Backups (N1): - New `backup` compose service (postgres:16-alpine) runs scripts/backup-loop.sh: immediate pg_dump on start, then nightly, gzip, 14-day rotation into ./backups on the host. Configurable via BACKUP_RETENTION_DAYS / BACKUP_INTERVAL_SECONDS. (Offsite copy is the documented next step.) Resource limits + healthchecks (N2): - deploy.resources.limits.memory on postgres (2g), app (1500m), nginx (256m), backup (256m) so no container can starve the others (the Nginx outage was a reminder). - Nginx now has a healthcheck hitting a new self-served `/nginx-health` endpoint on the default_server (no upstream dependency). Chat resilience (N3): - buildSystemPrompt() wraps its 4 Prisma queries in try/catch with safe defaults — if Postgres is down the assistant degrades instead of 500-ing. - Result is cached for 60s (only on healthy builds) so we don't run 4 queries per message; CMS edits still appear within the TTL. - POST fails fast with 503 if OPENAI_API_KEY is missing (instead of breaking mid-stream after headers are sent). - streamText gets an onError handler that logs + persists an `error` AiEvent. Idempotent submissions (N4): - consultation/route.ts and operations.ts now wrap the email-tracking UPDATE in try/catch — the lead/signal is already saved, so a telemetry hiccup can't 500 the request and trigger a duplicate retry. operations.ts also returns emailError. Performance (N5): - Index GlobalNode(application, isActive) — backs the case-study join on every application page. Migration 20260609130000_index_globalnode_application. Verified: next build compiles (Docker parity, SESSION_SECRET unset), TypeScript clean, prisma schema valid, golden tests 17/17, `docker compose config` valid.
