Jordan Ramos caf6ca4008 Add per-metric remediation plans and improve CI pipeline
Per-metric remediation plan scoping (GitLab issue #19):
- Add metric_id column to compliance_item_history table (migration)
- Extend PATCH /items/:hostname/metadata to accept metric_id/metric_ids
  for targeting specific metrics instead of all active items
- Add MetricChipSelector UI in detail panel for choosing which metrics
  to apply resolution_date and remediation_plan changes to
- Display per-metric labels (MetricChip or 'All metrics') on history entries
- Backward compatible: omitting metric_ids preserves hostname-level behavior

CI/CD pipeline improvements:
- Add migration idempotency integration test (runs against real Postgres)
- Add post-deploy smoke tests for compliance and VCL endpoints
- Bump lint --max-warnings from 10 to 25
- Configure varsIgnorePattern for _ prefix convention on unused vars

| Frontend serving | Express serves `frontend/build/` as static files on port 3001 |
| UI Icons | lucide-react |
| Charts | recharts |
| Spreadsheet parsing | xlsx (frontend), pandas + openpyxl (backend Python scripts) |
| Markdown rendering | react-markdown |

## Architecture: Single-Port Serving
Express on port 3001 serves **both** the API and the production frontend build:
- API routes: `/api/*` — handled by Express route handlers
- Frontend: everything else — served as static files from `frontend/build/`
There is no separate frontend server in production. The React dev server (`npm start` on port 3000) is only for local development with hot-reload. In production and on the dev server, you must run `npm run build` in `frontend/` after any frontend code change, then restart the backend.
**After editing frontend source files:**
```bash
cd frontend && npm run build # Compile new bundle into frontend/build/
# Then restart backend (or it will serve the new static files on next request)
```
The CI/CD pipeline handles this automatically — `build-frontend` stage runs before deploy.
## Common Commands
### Backend
```bash
cd backend
node setup.js # Initialize DB, tables, indexes, default admin user
node server.js # Start backend on port 3001 (serves API + frontend build)
```
### Frontend
```bash
cd frontend
npm install # Install dependencies
npm run build # Production build → frontend/build/ (REQUIRED after code changes)
npm start # Dev server on port 3000 (local dev only, NOT used in production)
npm test # Run tests (react-scripts test)
```
### Both servers (from project root)
```bash
./start-servers.sh # Start backend + frontend in background
./stop-servers.sh # Stop all servers
```
### Database Migrations (run from `backend/`)
```bash
node migrations/run-all.js # Runs all migrations in order (idempotent)
```
### Python Scripts (from `backend/scripts/`)
```bash
# Compliance xlsx parsing (called automatically by upload flow)
python3 parse_compliance_xlsx.py <file>
# Bulk notes import
python3 import_notes_from_csv.py input.csv --dry-run
python3 import_notes_from_csv.py input.csv
```
Python dependencies: `pandas>=2.0.0`, `openpyxl>=3.0.0` (install via apt or venv).
## Environment Configuration
- `backend/.env` — PORT, CORS_ORIGINS, SESSION_SECRET, NVD_API_KEY, Ivanti API credentials
- `frontend/.env` — REACT_APP_API_BASE, REACT_APP_API_HOST
- Both `.env` files are gitignored; see `.env.example` files for templates.
- React env vars are baked in at **build time** — you must rebuild (`npm run build`) after changing them.
## Code Style & Lint Rules
### Unused Variables
The frontend ESLint config enforces `no-unused-vars` as a warning. The CI pipeline fails if warnings exceed 25. To avoid lint failures:
- **Prefix intentionally-unused variables with `_`** — this suppresses the warning. The `varsIgnorePattern: "^_"` and `argsIgnorePattern: "^_"` rules are configured in `frontend/package.json`.
- Common patterns:
- `const [_unused, setFoo] = useState(...)` — destructured value you don't need
- `const _legacyRef = useRef(...)` — kept for future use
- `function handler(_event) { ... }` — required parameter signature but unused
- **Do not leave variables unprefixed if unused.** Either use them, remove them, or prefix with `_`.
- This applies to all frontend code written by the agent.
### Backend
No ESLint is configured for backend — the pipeline uses `node -c` syntax checking only. Keep code clean but there is no automated unused-var enforcement on the backend side.
## Ports
| Environment | URL | Notes |
|---|---|---|
| Production / Dev server | http://IP:3001 | Express serves API + static frontend build |
| Local dev (frontend only) | http://localhost:3000 | React dev server with hot-reload, proxies API to :3001 |
