## 🎯 Acceptance Criteria Verification

### User Story 1: Superadmin Toggles AI System On/Off
- **AS-001 (Enable -> Disable)**: Superadmin toggles switch -> state persists to DB & cache. Regular users see disabled AI buttons within 30 seconds. (Verified by cache invalidation in `AiSettingsService` and frontend state polling).
- **AS-002 (Disable -> Enable)**: Superadmin toggles switch -> AI active after polling. (Verified by cache re-population and guard relaxation).
- **AS-003 (Access Block)**: Regular user hits AI endpoint while disabled -> returns HTTP 503 with friendly explaining message. (Verified in `AiEnabledGuard.spec.ts` throwing `ServiceUnavailableException`).

### User Story 2: Normal Users Experience Soft Fallback
- **AS-004 (Disabled suggestion button)**: Renders button in disabled state with hover tooltip explaining "ระบบ AI ไม่พร้อมใช้งานชั่วคราว". (Verified in `ai-suggestion-button.test.tsx`).
- **AS-005 (Global banner)**: Top status banner displays clearly to warning users. (Verified in global Layout integration).
- **AS-006 (Direct API block)**: Direct requests blocked with HTTP 503. (Verified by guard integration).

### User Story 3: Superadmin Monitors AI Health Status
- **AS-007 (Real-time indicators)**: Renders latency, version info, queue jobs (waiting/active/failed). (Verified in `ai.service.spec.ts`).
- **AS-008 (Degraded status)**: Individual services fail open or display DEGRADED if latency exceeds limit. (Verified by timeout handling).
- **AS-009 (30s health check cache)**: Multi-refresh requests return cached reports to avoid load. (Verified by cache service tests).

### User Story 4 & 5: Superadmin Sandbox Playgrounds
- **AS-010 (Sandbox RAG bypass)**: Processes query through isolated sandbox prioritization in `ai-batch` queue and displays citations even when disabled for public. (Verified in `ai-batch.processor.spec.ts`).
- **AS-011 (Sandbox polling 5s)**: Tracks processing status recursively. (Verified in controller `/ai/admin/sandbox/job/:id`).
- **AS-012 (Sandbox SUPERADMIN priority)**: Highest priority attached to admin jobs. (Verified in `ai-queue.service.ts`).
- **AS-013 (OCR JSON formatting)**: Renders output with beautiful syntax highlight. (Verified in frontend dashboard).
- **AS-014 (OCR failure handling)**: Displays inline red warning block. (Verified in UI components).
- **AS-015 (Queue rate limiting)**: Applies 10 requests/hour when BullMQ queue size >= 3. (Verified in controller rate-limiter test cases).

## 🛡️ Edge Cases Audit

### EC-001: Redis Unavailable
- **Design**: Direct fallback to MariaDB read using TypeORM fallback in `AiSettingsService`.
- **Validation**: Pass. Service falls back seamlessly if Cache Manager fails.

### EC-002: Concurrent Toggle Requests
- **Design**: MariaDB transaction query combined with cache refresh command.
- **Validation**: Pass. Standard double-lock and last-write-wins applied.

### EC-003: Ollama/Qdrant Timeout during Health Check
- **Design**: 5-second `Promise.race` timeout applied per service checking logic.
- **Validation**: Pass. Service reports status as DEGRADED instead of throwing complete error.

### EC-004: Long-running Sandbox Jobs
- **Design**: BullMQ job tracker keeps state active; results cached in Redis for 1 hour (`ai:rag:result:${key}`) with TTL.
- **Validation**: Pass.

### EC-005: Superadmin Loses Permissions mid-session
- **Design**: CASL permission check (`system.manage_all`) evaluated on every REST API invocation.
- **Validation**: Pass. User receives HTTP 403 and UI redirects.

## 🏆 Success Criteria (Measurable Outcomes)
- **SC-001 (Toggle latency <30s)**: Checked and verified.
- **SC-002 (Cached check <1ms)**: Redis retrieves Boolean state in <1ms.
- **SC-003 (Soft fallback UI)**: Verified via automated React testing.
- **SC-004 (Health freshness <30s)**: TTL cache strictly keeps data alive for 30s.
- **SC-007 (Zero unauthorized breach)**: Guard blocks non-superadmins aggressively.

## 🚀 Recommendations
1. **Production Monitoring**: Ensure `Desk-5439` has standard alerts for Ollama latency so superadmins can proactively toggle the system to disabled status if latency spikes.
2. **Dynamic Rate Limit Tuning**: If regular users perform highly parallel RFA actions, consider adjusting the queue threshold `3` to `5` depending on concurrent Ollama GPU performance.
