# Build Health Audit — ln-622
**Score: 5.5/10** | Issues: 28 (C:0 H:5 M:18 L:5)
**Date:** 2026-04-30 | **Stack:** Python 3.11 / FastAPI / Celery + React 19 / Vite / TypeScript 5.8
---
## 1. Compiler / Linter Errors
### Backend — ruff: 1314 errors (HIGH)
`ruff check app/` exits non-zero with 1314 violations. The ruff config in `pyproject.toml` uses **deprecated top-level `select`/`ignore`/`per-file-ignores`** instead of `[tool.ruff.lint]` — ruff emits a warning on every run.
Top violation codes:
| Code | Meaning | Volume |
|------|---------|--------|
| I001 | Import block unsorted | ~400 |
| UP | pyupgrade (f-strings, typing aliases) | ~500 |
| B | flake8-bugbear | ~200 |
| F401 | Unused import | 58 |
Most violations are **auto-fixable** (`ruff check --fix`). The unsorted imports and UP rules are cosmetic but make CI noisy and block future enforcement.
**Severity: HIGH** — CI cannot gate on ruff without fixing this first.
### Frontend — ESLint: 36 problems (30 errors, 6 warnings) (MEDIUM)
Key errors:
| File | Rule | Count |
|------|------|-------|
| `contexts/GlobalWebSocketContext.tsx:56` | `react-refresh/only-export-components` | 1 |
| `contexts/NotificationContext.tsx:91` | `react-refresh/only-export-components` | 1 |
| `contexts/ToastContext.tsx:83` | `react-refresh/only-export-components` | 1 |
| `lib/api.ts:539` | `@typescript-eslint/no-explicit-any` | 1 |
| `routes/admin/QCDetail.tsx` | `@typescript-eslint/no-explicit-any` | 6 |
| `routes/AcceptInvite.tsx` | `@typescript-eslint/no-explicit-any` | 1 |
| `routes/jobs/JobDetail.tsx` | `no-unused-vars` (err catch) | 2 |
| `hooks/__tests__/useJob.test.tsx` | `no-unused-vars` | 1 |
| `tests/helpers/auth.ts` | `no-explicit-any` | 3 |
**Severity: MEDIUM** — build succeeds, but `any` types and react-refresh errors degrade DX and HMR.
---
## 2. Type Errors
### Frontend — tsc: CLEAN ✓
`tsc --noEmit` exits 0. No TypeScript compilation errors. The `any` issues above are ESLint-level, not tsc errors.
### Backend — mypy: NOT RUN
Cannot run mypy outside the poetry venv. Needs `poetry run mypy .` inside Docker or an activated venv.
**Severity: LOW** (mypy not blocking, but should be run in CI)
---
## 3. Tests
### Frontend — vitest: 13 failed / 75 total (HIGH)
8 test files affected:
| Test | Failures | Root cause |
|------|----------|-----------|
| `auth.test.ts` | 1 | Mock shape mismatch — response has extra field `organizationId` |
| `StatusBadge.test.tsx` | 1 | Unknown status no longer renders text (component changed) |
| `VttEditor.test.tsx` | 1 | Multiple elements found for `Insert cue before` title — DOM duplication |
| `useJob.test.tsx` | 3 | `useApproveEnglish` — pending state never resolves in test (timeout 1s); `useCreateJob` arg mismatch |
| `UploadDropzone.test.tsx` | 6 | Text broken across elements — test uses exact string match, component renders in `<span>` nodes |
| `useJobStatusWebSocket.test.tsx` | 1 | (see output) |
**Severity: HIGH** — 17% test failure rate. Several are stale tests from component refactors (UploadDropzone, StatusBadge).
### Backend — pytest: CANNOT RUN (CRITICAL)
Running `pytest` outside poetry venv fails with `ModuleNotFoundError` for `fastapi`, `aiohttp`, etc. Tests must be run with `poetry run pytest` inside Docker or an activated poetry environment.
The `backend/.venv` exists but appears to be a plain venv, not the poetry-managed one. **Tests are effectively unrunnable in local dev without explicit poetry activation.**
**Severity: CRITICAL** — Developers with system Python cannot run tests without explicit setup steps.
---
## 4. Build Configuration Issues
### ruff config deprecated (MEDIUM)
`pyproject.toml` uses `[tool.ruff]` top-level `select`, `ignore`, `per-file-ignores`. Current ruff ≥ 0.2 expects `[tool.ruff.lint]`. Fix:
```toml
# Before
[tool.ruff]
select = ["E", "W", ...]
ignore = ["E501", ...]
# After
[tool.ruff]
target-version = "py311"
line-length = 88
[tool.ruff.lint]
select = ["E", "W", ...]
ignore = ["E501", ...]
```
### Backend venv mismatch (MEDIUM)
`backend/.venv` cannot run `ruff`, `pytest`, or `mypy` — they are installed in the poetry-managed venv, not this one. Confusing to new devs.
### AGENTS.md commands incorrect (LOW)
`AGENTS.md` documents `cd backend && poetry run pytest` but the backend has `.venv` and `pyproject.toml` with no Makefile wrapper. The actual working path is `cd backend && .venv/bin/python -m pytest` or requires `poetry shell`.
---
## Summary
| Check | Result | Severity |
|-------|--------|---------|
| ruff backend | 1314 violations (auto-fixable) | HIGH |
| ESLint frontend | 36 problems | MEDIUM |
| tsc frontend | ✓ Clean | OK |
| mypy backend | Not runnable locally | LOW |
| vitest frontend | 13/75 failing | HIGH |
| pytest backend | Not runnable locally | CRITICAL |
| ruff config | Deprecated syntax | MEDIUM |
| venv setup | Confusing / broken | MEDIUM |

# Code Quality Audit — ln-624
**Score: 5.0/10** | Issues: 22 (C:2 H:8 M:9 L:3)
**Date:** 2026-04-30
---
## 1. God Classes / Files (> 500 lines)
| File | Lines | Severity |
|------|-------|---------|
| `backend/app/api/v1/routes_jobs.py` | 2882 | **CRITICAL** |
| `frontend/src/routes/admin/QCDetail.tsx` | 2079 | **CRITICAL** |
| `backend/app/services/video_renderer.py` | 1695 | **HIGH** |
| `frontend/src/routes/jobs/JobsList.tsx` | 1246 | **HIGH** |
| `frontend/src/lib/api.ts` | 1056 | **HIGH** |
| `backend/app/tasks/translate_and_synthesize.py` | 1019 | **HIGH** |
| `frontend/src/routes/jobs/NewJob.tsx` | 1038 | **HIGH** |
| `frontend/src/types/api.ts` | 891 | **MEDIUM** |
| `frontend/src/routes/jobs/JobDetail.tsx` | 732 | **MEDIUM** |
| `frontend/src/routes/admin/UserDetail.tsx` | 523 | **MEDIUM** |
| `frontend/src/hooks/useJobStatusWebSocket.ts` | 443 | **MEDIUM** |
**routes_jobs.py at 2882 lines** is the worst offender — it mixes upload, approval, translation, TTS, VTT editing, download, admin, and websocket concerns in a single router. Splitting by domain (e.g., `routes_upload.py`, `routes_vtt.py`, `routes_review.py`, `routes_tts.py`) would bring each under 500 lines.
**QCDetail.tsx at 2079 lines** handles the entire QC workflow, VTT display, audio preview, language selection, and approval modals in one component. Needs extraction of at minimum: `LanguageQCPanel`, `VttReviewView`, `ApprovalModal`.
---
## 2. Long Methods (> 100 lines)
| File:line | Function | Length | Severity |
|-----------|---------|--------|---------|
| `tasks/translate_and_synthesize.py:109` | `_async_translate_and_synthesize()` | 485 lines | **CRITICAL** |
| `services/video_renderer.py:487` | `_render_pause_insert_method()` | 419 lines | **CRITICAL** |
| `tasks/ingest_and_ai.py:53` | `ingest_and_ai_task_impl()` | 276 lines | **HIGH** |
| `tasks/rerender_accessible_video.py:110` | `_async_rerender_accessible_video()` | 280 lines | **HIGH** |
| `tasks/render_accessible_video.py:56` | `_async_render_accessible_video()` | 287 lines | **HIGH** |
| `api/v1/routes_jobs.py:1552` | `update_job_vtt_content()` | 215 lines | **HIGH** |
| `tasks/notify.py:29` | `run_async()` | 169 lines | **HIGH** |
| `api/v1/routes_jobs.py:2738` | `update_tts_preferences()` | 144 lines | **MEDIUM** |
| `services/whisper_service.py:241` | `_find_sentence_boundaries()` | 120 lines | **MEDIUM** |
| `services/gemini.py:591` | `analyze_accessible_video_placement()` | 132 lines | **MEDIUM** |
The two most critical ones (`_async_translate_and_synthesize` at 485 lines and `_render_pause_insert_method` at 419 lines) are orchestrator-style functions with sequential pipeline steps. They could be split into named pipeline stages, each ~50 lines.
---
## 3. Deep Nesting
Not systematically scanned with a tool (radon/lizard not installed). The long functions above likely contain 4–5+ nesting levels given their complexity.
---
## 4. Too Many Parameters
| Location | Function | Params | Severity |
|----------|---------|--------|---------|
| `services/gemini.py` | `extract_accessibility_targeted()` | 7+ | **MEDIUM** |
| `tasks/translate_and_synthesize.py` | `_generate_language_tts()` | 8+ | **MEDIUM** |
Pattern: many functions pass `db`, `job`, `language`, `settings`, `gcs_client`, etc. individually instead of grouping into a context dataclass.
---
## 5. Magic Numbers
### Backend (MEDIUM)
Scattered timing constants without named definitions:
- TTS retry delays (hardcoded seconds)
- chunk sizes in upload
- Audio padding values in video_renderer.py
### Frontend (LOW)
Mostly clean. Some inline pixel values in Tailwind (acceptable). No concerning business-logic magic numbers found.
---
## 6. N+1 Query Patterns (MEDIUM)
Potential N+1 patterns found:
- `app/main.py:102` — `async for job_doc in db.jobs.find(...)` — check if this iterates and makes additional queries per document
- `app/core/dependencies.py:185` — `async for m in db.memberships.find(...)` — membership lookup per request in auth middleware (acceptable if cached, but no caching observed)
- `app/core/authz.py:54` — `async for doc in db.memberships.find(...)` — similar pattern in auth check
These are all async iterators over `find()` — not necessarily N+1 if no nested DB calls, but should be reviewed for `.find()` calls inside the loop body.
---
## 7. Method Signature Quality
### Boolean flag parameters (MEDIUM)
Several async functions in tasks accept `bool` flags controlling behavior variants (e.g., `skip_tts`, `force_regenerate`). These should be enums or separate functions.
### Unclear return types (MEDIUM)
Some routes return `dict` or untyped responses instead of Pydantic response models. `routes_admin_production.py` has a few endpoints returning bare dicts.
---
## 8. Side-Effect Cascade Depth
`_async_translate_and_synthesize()` at 485 lines is the worst case: it writes to GCS, updates MongoDB, dispatches TTS tasks, sends notifications, and updates job status — 5+ distinct side-effect categories from a single function call. This warrants extraction into an orchestrator that delegates to named sink functions.
---
## Summary
| Check | Status | Severity |
|-------|--------|---------|
| God files (>500L) | 11 files | CRITICAL×2, HIGH×4 |
| Long methods (>100L) | 10 functions | CRITICAL×2, HIGH×5 |
| N+1 patterns | 3 potential | MEDIUM |
| Magic numbers | Some in tasks | MEDIUM |
| Method signatures | Boolean flags, unclear returns | MEDIUM |
| Side-effect cascade | translate_and_synthesize | HIGH |
**Primary recommendation:** Split `routes_jobs.py` and `QCDetail.tsx` — these two files account for the majority of the quality debt.

# Dependencies & Reuse Audit — ln-625
**Score: 7.5/10** | Issues: 9 (C:0 H:2 M:5 L:2)
**Date:** 2026-04-30
---
## 1. Vulnerability Scan (CVE/CVSS)
### Frontend — npm audit: ✓ CLEAN
```
Total packages: 479
Vulnerabilities: info:0 low:0 moderate:0 high:0 critical:0 total:0
```
Zero CVEs. Excellent.
### Backend — pip-audit: NOT RUN
`pip-audit` not installed in local env. Recommended to add to CI:
```bash
pip install pip-audit && pip-audit -r requirements.txt
```
Given many heavy deps (Celery 5.3, google-cloud-*, faster-whisper, aiohttp), a CI scan is strongly advised.
---
## 2. Outdated Packages
### Frontend — npm outdated (many minor/major updates pending)
**MAJOR version gaps (HIGH):**
| Package | Installed | Latest | Notes |
|---------|-----------|--------|-------|
| `@azure/msal-browser` | 4.25.0 | **5.9.0** | MSAL v5 has breaking API changes |
| `@azure/msal-react` | 3.0.20 | **5.3.2** | Paired with msal-browser, coordinated upgrade needed |
| `@sentry/react` | 8.55.0 | **10.51.0** | Sentry v10 has breaking changes |
| `typescript` | 5.8.3 | **6.0.3** | TS 6 has strictness changes |
| `vite` | 7.3.2 | **8.0.10** | Vite 8 breaking changes |
| `eslint` | 9.33.0 | **10.2.1** | ESLint 10 config format may change |
| `jsdom` | 26.1.0 | **29.1.1** | Test environment |
**Minor updates (LOW-MEDIUM):** Most other packages have minor/patch updates pending (react 19.1→19.2, tailwindcss 4.1→4.2, etc.)
**Recommendation:** Keep MSAL and Sentry on current major until dedicated upgrade sprint. React, TailwindCSS, react-query minor updates are safe to apply immediately.
### Backend — pip outdated: pip-audit not available
Based on pyproject.toml dates vs ecosystem:
- `ruff ^0.1.6` → installed ruff is `0.15.12` (already updated, good)
- `google-genai ^1.56.0` → recently updated per git log
- `faster-whisper ^1.2.0` → check for 1.x updates
---
## 3. Unused Dependencies
### Backend — `sendgrid` (MEDIUM)
`pyproject.toml` lists `sendgrid = "^6.11.0"`. However:
- The actual emailer (`app/services/emailer.py`) uses **Mailgun** REST API via `httpx`
- `sendgrid` is referenced **only** in `app/core/config.py` as a dead config field `sendgrid_api_key: str = ""` with comment `# Email (Mailgun — primary; sendgrid_api_key kept for backward compat)`
- No `import sendgrid` anywhere in app code
**Action:** Remove `sendgrid` from `pyproject.toml` dependencies and remove the `sendgrid_api_key` config field.
### Frontend — no unused dependencies found
- `axios` → used in `lib/api.ts`
- `@azure/msal-*` → used in `main.tsx`, `routes/Login.tsx`
- `date-fns` → used in 5+ components
- `zustand`, `@tanstack/react-query`, `react-hook-form`, `zod` → all actively used
- `react-dropzone` → used in upload components
---
## 4. Available Native Alternatives
### Frontend — axios vs fetch (LOW)
`axios` is used for all API calls in `lib/api.ts`. The project targets modern browsers and uses Vite. Native `fetch` + `AbortController` could replace axios, reducing bundle by ~14kb gzipped. However, axios provides request/response interceptors that are actively used for auth token refresh — migration effort is medium. **Not urgent.**
---
## 5. Custom Implementations
No custom crypto or hand-rolled validation libraries found. All auth uses `python-jose` + `libpass` (bcrypt). VTT parsing is domain-specific and not replaceable by a library. No concerns.
---
## Summary
| Check | Result | Severity |
|-------|--------|---------|
| Frontend CVEs | ✓ 0 vulnerabilities | OK |
| Backend CVEs | ⚠ Not scanned | MEDIUM |
| Frontend major updates | MSAL×2, Sentry, TS, Vite, ESLint | HIGH |
| Frontend minor updates | Many | LOW |
| Backend unused dep | `sendgrid` in pyproject.toml | MEDIUM |
| Native alternatives | axios → fetch possible | LOW |
| Custom implementations | None found | OK |

# Dead Code Audit — ln-626
**Score: 7.0/10** | Issues: 14 (C:0 H:0 M:6 L:8)
**Date:** 2026-04-30
---
## 1. Unused Imports (Python — F401)
ruff detected **58 unused import violations** across backend. Sample:
| File | Unused import |
|------|--------------|
| `routes_admin.py:9` | `get_current_user` |
| `routes_admin.py:11` | `verify_password` |
| `routes_admin.py:16` | `ChangePasswordRequest` |
| `routes_admin.py:23` | `log_security_event` |
| (+ 54 more across all files) | |
All are auto-fixable with `ruff check --fix --select F401`. The `__init__.py` files are correctly excluded via `per-file-ignores`.
**Severity: MEDIUM** — clutters imports, increases cognitive load when reading files.
---
## 2. Deprecated / Legacy Types (Frontend)
`frontend/src/types/api.ts` contains 3 deprecated exported types with JSDoc markers:
| Line | Type | Marker |
|------|------|--------|
| 96 | `TtsVoicesResponse` | `@deprecated Use ProviderVoicesResponse instead` |
| 137 | `TtsOptionsResponse` | `@deprecated Use ProviderOptionsResponse instead` |
| 555-566 | `Client` / `OrganizationLegacy` | `@deprecated Use Organization instead` + `export { Client as OrganizationLegacy }` |
These types are still exported, meaning consumers could use them by mistake. If no external consumers exist (library not published), they should be deleted.
**Severity: MEDIUM** — active deprecation markers indicate intent to remove. Leaving them causes confusion.
---
## 3. Legacy Status Values (Frontend)
`frontend/src/types/api.ts:12,14`:
```ts
| "tts_failed" // legacy: keep for back-compat
| "render_failed" // legacy: keep for back-compat
```
These job statuses are marked as legacy. If the backend no longer emits them, they are dead type branches. If it still does (for old jobs in MongoDB), they're valid — but should be clearly documented with a removal condition.
**Severity: LOW** — no runtime impact, but requires clarification.
---
## 4. Backward Compatibility Code (Frontend)
### lib/api.ts:239 — Legacy approval method (MEDIUM)
```ts
// Legacy method - calls approve_source for backwards compatibility
```
A backward-compat shim in the API client. If all callers have been updated to the new method, this should be removed.
### VideoWithCaptions.tsx:16–43 — Legacy single-language props (MEDIUM)
```ts
// Legacy single-language props (still supported)
sourceLanguage?: string; // Language code for legacy props
// Legacy props
// Combine legacy props with tracks (use useMemo to prevent recreation)
```
The component maintains backward-compat with old single-language prop API. If no callers use these legacy props, they can be removed.
### JobDetail.tsx:41 — Legacy status mapping (LOW)
```ts
// Handle legacy approved_english/approved_source statuses (map to pending_final_review)
```
Status mapping shim for old job records. Should be removed after all existing jobs are migrated.
---
## 5. Commented-Out Code (Backend)
| File | Line | Content |
|------|------|---------|
| `telemetry/tracing.py:5` | `# from opentelemetry.exporter.gcp.trace import CloudTraceSpanExporter # Disabled for local dev` | GCP trace exporter disabled |
| `telemetry/metrics.py:5` | `# from opentelemetry.exporter.prometheus import PrometheusMetricReader # Disabled for local dev` | Prometheus reader disabled |
| `pyproject.toml` | `# opentelemetry-exporter-prometheus = ... # Temporarily disabled - version conflicts` | Dep commented out |
These are intentional (local dev vs prod config), not dead code. However, the conditional should be expressed via environment config, not source comments. **Low priority.**
**Severity: LOW**
---
## 6. Leftover .old Files (MEDIUM)
| File | Age | Action |

These files have no build references. Git history preserves them.

## 7. Unused Dockerfiles
| File | Referenced in compose? |
|------|----------------------|
| `backend/Dockerfile.ffmpeg-service` | No — ffmpeg is embedded in main worker |
| `backend/Dockerfile.cloudrun` | Yes — referenced for Cloud Run deploys |
| `backend/Dockerfile.whisper-service` | Yes — whisper-worker service in compose |
`Dockerfile.ffmpeg-service` appears to be dead — the main Dockerfile handles ffmpeg. Should be confirmed and deleted if unused.
**Severity: LOW**
---
## 8. Dead Config Field
`backend/app/core/config.py:272`:
```python
sendgrid_api_key: str = "" # Email (Mailgun — primary; sendgrid_api_key kept for backward compat)
```
`sendgrid` package not used. Config field and `secrets_config.py` secret reference both dead.
**Severity: MEDIUM** — misleads ops into configuring a sendgrid secret that has no effect.
---
## Summary
| Check | Issues | Severity |
|-------|--------|---------|
| Unused Python imports | 58 (auto-fixable) | MEDIUM |
| Deprecated TS types | 3 types | MEDIUM |
| Backward-compat shims | 3 in frontend | MEDIUM |
| Commented-out code | 3 telemetry lines | LOW |
| .old files | 3 files | MEDIUM |
| Unused Dockerfile | Dockerfile.ffmpeg-service | LOW |
| Dead config field | sendgrid_api_key | MEDIUM |
| Legacy status values | 2 status strings | LOW |

# =============================================================================
# Check Apache logs:
# sudo tail -f /var/log/apache2/ai-sandbox-error.log
# sudo tail -f /var/log/apache2/ai-sandbox-access.log
#
# Check if backend is running:
# curl http://localhost:8000/health
#
# Check Docker containers:
# cd /opt/accessible-video
# docker-compose ps
#
# Common issues:
# - 502 Bad Gateway: Backend container not running
# - 404 Not Found: Frontend not deployed or Apache alias incorrect
# - WebSocket fails: mod_proxy_wstunnel not enabled
# - CORS errors: Check backend CORS configuration, not Apache
# sudo apache2ctl configtest
# sudo systemctl reload apache2
# curl -I https://ai-sandbox.oliver.solutions/video-accessibility/
