# Task 023 — Production Readiness

## Objective

Harden the platform for production deployment: security review, monitoring, backups, performance, and operational runbook.

## Scope

- Error tracking integration (e.g. Sentry)
- Structured logging
- MongoDB backup verification
- Load test light on campaign send path
- CI pipeline lint/build/test
- Complete `docs/12-deployment.md` runbook
- Rate limits on auth and tracking endpoints
- README production section

**Out of scope:** Multi-region HA (document as future).

## Requirements

1. All required env vars validated at startup in production mode.
2. Health check includes DB connectivity.
3. Deployment checklist in deployment doc completed.
4. No secrets in logs; dependency audit addressed.
