 ```
 
 The script executes linting followed by the backend and frontend test suites (each with coverage reporting). Coverage thresholds are enforced by Jest to guard against regressions.
+The helper waits for the ad-hoc PostgreSQL container, honours the backend entrypoint (which now blocks on database readiness, runs migrations, and optionally seeds), and then runs both suites with coverage thresholds enforced.

+# Operations Runbook
+
+This document captures the operational playbooks for the MerchantsOfHope Supply & Demand Portal. It is intended for on-call engineers and SREs maintaining the platform across Coolify environments.
+
+## 1. Service Topology
+
+- **Backend API (`merchantsofhope-supplyanddemandportal-backend`)**
+  - Node.js 18, Express server on port 3001.
+  - Entry point waits for PostgreSQL, runs migrations, optional seeding (`RUN_SEED`).
+  - Health probe: `GET /api/health`.
+  - Persistent uploads stored at `/app/uploads/resumes` (mounted volume required in production).
+- **Frontend (`merchantsofhope-supplyanddemandportal-frontend`)**
+  - React 18 application served by the CRA dev server (in dev) or static bundle (in production image).
+  - Communicates with the backend via `REACT_APP_API_URL` (set to the internal service URL).
+- **PostgreSQL (`merchantsofhope-supplyanddemandportal-database`)**
+  - PostgreSQL 15, health-checked via `pg_isready`.
+  - Volume-backed data directory `merchantsofhope-supplyanddemandportal-postgres-data`.
+
+## 2. Environment Variables
+
+| Variable | Purpose | Default |
+| --- | --- | --- |
+| `POSTGRES_*` | Database credentials used by backend and DB container | See `.env.example` |
+| `DATABASE_URL` | Overrides assembled connection string | Derived automatically |
+| `JWT_SECRET` | Required for signing auth tokens | none (must be supplied) |
+| `RATE_LIMIT_MAX`, `RATE_LIMIT_WINDOW_MS` | Express rate limiter configuration | 100 req / 15 min |
+| `DB_POOL_MAX`, `DB_POOL_IDLE_MS`, `DB_POOL_CONNECTION_TIMEOUT_MS` | pg connection pool tuning | 10 / 30000 / 5000 |
+| `DB_WAIT_TIMEOUT_MS` | Maximum wait for database readiness in entrypoint | 60000 |
+| `RUN_MIGRATIONS` | Run schema migrations on container boot | `true` |
+| `RUN_SEED` | Run seed data on container boot | `false` |
+| `UPLOAD_DIR` | Resume storage path | `uploads/resumes` |
+
+## 3. Deployments (Coolify)
+
+1. Ensure the Gitea pipeline has published new backend/frontend images (see workflow summary for SHA tags).
+2. In Coolify, update `BACKEND_IMAGE` / `FRONTEND_IMAGE` environment variables to the new tags.
+3. Trigger a deployment; Coolify will:
+   - Bring up PostgreSQL (if not already running).
+   - Start backend, wait for DB, run migrations, and expose `/api/health`.
+   - Start frontend once backend healthcheck passes.
+4. Post-deploy checks:
+   - `curl https://<domain>/api/health` returns `200` with JSON payload.
+   - Frontend login screen reachable.
+   - Review container logs for migration output (`docker compose logs backend` in Coolify shell).
+
+## 4. Rollback Procedure
+
+1. Identify the previous known-good image tags (from Gitea workflow history or Coolify activity log).
+2. Update `BACKEND_IMAGE` / `FRONTEND_IMAGE` to the old tags.
+3. Redeploy in Coolify. Migrations are idempotent; no additional action needed.
+4. Validate health endpoints and smoke-test the UI.
+
+## 5. Local Development
+
+- Run `docker compose up --build` to start the stack. The backend container waits for PostgreSQL, runs migrations automatically, and skips seeding by default. To seed once, run `RUN_SEED=true docker compose up backend` or execute `docker compose exec ... npm run seed` manually.
+- `./scripts/run-ci-tests.sh` runs lint + unit tests with the same coverage thresholds as CI.
+- Backend tests rely on Docker; ensure Docker Desktop/Engine is running.
+
+## 6. Backup & Restore
+
+### Database
+- Use `docker compose exec merchantsofhope-supplyanddemandportal-database pg_dump -U <user> <db>` to generate a dump file.
+- Restore via `psql` piping the dump into the running container.
+
+### Uploads
+- Archive the `merchantsofhope-supplyanddemandportal-uploads` volume (Coolify: Settings → Backups → Volume Snapshot).
+
+## 7. Monitoring & Alerting
+
+- Healthcheck endpoints should be wired into external monitoring (e.g., Uptime Kuma, Grafana Cloud).
+- Rate limiter defaults protect against bursts; adjust `RATE_LIMIT_MAX` / `RATE_LIMIT_WINDOW_MS` if legitimate traffic patterns trigger 429s.
+
+## 8. Incident Response Checklist
+
+1. **Validate Health** – `curl` backend health endpoint, inspect Coolify container logs.
+2. **Check Database** – `docker compose exec ... pg_isready` and `
+   docker compose exec ... psql -c 'SELECT NOW();'`.
+3. **Restart Services** – In Coolify or locally, redeploy backend/front containers (entrypoint will re-run migrations safely).
+4. **Rollback if Needed** – Follow rollback steps above.
+5. **Postmortem** – Capture root cause, update this runbook with remediation notes.
+
+## 9. Security Posture
+
+- JWT secrets must be at least 32 bytes and rotated regularly.
+- Uploaded files are sanitized and stored on disk; configure antivirus scanning if compliance requires it.
+- Rate limiting is enabled globally; consider pairing with IP allowlists at the reverse proxy if stricter controls are needed.
+
+Keep this runbook updated as infrastructure evolves.
