## SLA Requirements

Think through multiple failure scenarios:

**Scenario 1: LLM Provider Outage**
- Detection mechanism
- Fallback behavior
- User communication

**Scenario 2: Vector DB Degradation**
- Partial failure handling
- Quality vs availability trade-off

**Scenario 3: Embedding Service Latency Spike**
- Timeout strategies
- Cached embedding fallbacks

For each scenario, provide:
1. Circuit breaker configuration
2. Fallback implementation code
3. Alerting thresholds
4. Recovery procedures
