## Edge Case Review

| Edge Case | Status | Notes |
| --- | --- | --- |
| VRAM query failure -> `keep_alive: 0` | Handled | explicit safe default in backend + sidecar (T017, T031) |
| caller sends forbidden profile/model fields | Handled | DTO/controller tests cover this (T007, T030) |
| admin-only large-context when VRAM insufficient | Handled | Contract removal prevents caller input; no path exists |
| OCR job races with main model generation | Handled | high-pressure/deep-analysis path forces unload (T017) |
| CPU fallback timeout must fail clearly | Handled | 504 implemented in sidecar (T022) |
| Ollama `/api/ps` schema drift after cutover | Handled | safe default `available=0` path exists (T031) |
| headroom snapshot/request race acceptable | Handled | implementation follows spec assumption |

## Key Findings

1. Implementation is fully aligned with the runtime-policy refactor design across all 5 workstreams: policy mapping, canonical naming, adaptive OCR residency, retrieval CPU fallback, and queue policy.
2. All 41 tasks from tasks.md have been completed, including delta SQL application, backend services, frontend UI, sidecar Python code, and comprehensive test coverage.
3. The spec artifact FR-A02 correctly describes the DTO contract - `CreateAiJobDto` accepts `type`, `documentPublicId`, `attachmentPublicId`, `payload`, and `projectPublicId` to support rag-query/query and tenant isolation requirements.
4. Backend tests (ai-policy.service.spec.ts, ocr-residency.spec.ts, vram-monitor.service.spec.ts, queue-policy.spec.ts, ai.controller.spec.ts) provide comprehensive coverage of all functional requirements.
5. Frontend types and UI components (types/ai.ts, admin-ai.service.ts, OcrSandboxPromptManager.tsx, admin/ai/page.tsx) correctly display canonical names (`np-dms-ai`, `np-dms-ocr`) across all user-facing surfaces.
6. Sidecar Python code (app.py, vram_monitor.py, residency_policy.py, test_retrieval_fallback.py) implements adaptive OCR residency and CPU fallback for retrieval acceleration.
7. All edge cases are handled with safe defaults (keep_alive=0 on VRAM query failure, CPU fallback on GPU pressure, HTTP 504 on timeout).

## Recommendations

1. Deploy backend + frontend changes to staging environment for integration testing.
2. Deploy OCR sidecar updates to Desk-5439 (app.py with adaptive keep_alive, CPU fallback logic).
3. Run manual validation per quickstart.md to verify end-to-end behavior in real environment.
4. Monitor production metrics after cutover to validate SC-003 (OCR cold start improvement) and SC-006 (lightweight job throughput).
5. Update quickstart.md if any manual validation steps need adjustment based on actual deployment experience.
