## 1. Deployment

### Steps

1. <!-- e.g. Push to GitHub → triggers build -->
2. <!-- e.g. New container builds -->
3. <!-- e.g. Health check passes -->
4. <!-- Verification step -->

### Verification

```bash
# Verify deployment succeeded
```

---

## 2. Emergency Rollback

### When to Use

<!-- Under what conditions should a rollback be triggered? -->

### Steps

```bash

### Constraints

- <!-- e.g. Database migrations must be backward-compatible -->

---

## 3. Health Monitoring

### Endpoints

|----------|:---:|---------|
| <!-- e.g. GET /health --> | No | Liveness check |
| <!-- e.g. GET /health/detailed --> | Yes | Component-level status |

### Response Interpretation

| Status | Action |
|--------|--------|
| `healthy` | All systems operational |
| `degraded` | Non-critical issue, investigate |

### Severity Levels

| Level | Definition | Response Time | Escalation |
|-------|-----------|:---:|------------|
| **P0** | System down | Immediate | Page on-call |
| **P1** | Major feature broken | 15 min | Notify team lead |
| **P2** | Minor issue | 1 hour | Create ticket |
| **P3** | Cosmetic/low impact | Next sprint | Backlog |

### Common Outage Scenarios

| Scenario | Impact | Mitigation |
|----------|--------|------------|
| <!-- e.g. Database down --> | <!-- e.g. All writes fail --> | <!-- e.g. Switch to read-only mode --> |
