+# TestAnalyser Agent Notes
+
+This repository has two active code areas:
+
+- `/` - Vite + React frontend
+- `/server` - Express + Prisma backend
+
+Ignore `/_ref`. It is a reference copy, not an active part of the app.
+
+## Working Areas
+
+- Frontend source lives in `src/`.
+- Static assets live in `public/`.
+- Backend-specific guidance lives in `server/AGENTS.md`.
+
+## Common Commands
+
+From the repo root:
+
+```bash
+npm install
+npm run dev
+npm run build
+npm run lint
+```
+
+From `server/`:
+
+```bash
+npm install
+npm run dev
+npm run build
+npx prisma migrate deploy
+npx prisma generate
+```
+
+## Environment
+
+Frontend env file:
+
+- `.env`
+- `VITE_API_BASE_URL`
+- `VITE_API_URL`
+
+Backend env file:
+
+- `server/.env`
+- `DATABASE_URL`
+- `JWT_SECRET`
+- `ENCRYPTION_KEY`
+- `CORS_ORIGIN`
+
+## Frontend Conventions
+
+- TypeScript is strict enough that quick `any` patches usually cause follow-up cleanup. Prefer explicit local types.
+- Path alias `@/*` maps to `src/*`.
+- The app uses React Router and store-driven state in `src/lib/store.tsx`.
+- UI components mostly come from the local `src/components/ui/` layer.
+- If you change question/test flows, check both `src/pages/TestDetail.tsx` and `src/pages/QuestionDetail.tsx`.
+
+## Verification Expectations
+
+For frontend changes, run:
+
+```bash
+npm run lint
+npm run build
+```
+
+For backend changes, run:
+
+```bash
+cd server
+npm run build
+```
+
+If a change crosses frontend/backend boundaries, run all three.
+
+## Deployment Notes
+
+- GitHub Pages deploy is handled by `.github/workflows/pages.yaml`.
+- Pages auto-deploys on pushes to `master` when `server/**` is unchanged.
+- Server changes do not trigger the Pages deploy workflow.
+
+## Known Constraints
+
+- `vite-plugin-pwa@1.2.0` is currently compatible with Vite 7 in this repo. Do not bump Vite to 8 without resolving that compatibility first.
+- Large refactors around hooks can trigger stricter React Hooks lint rules. Keep handler dependencies stable and avoid synchronous state writes inside effects unless you intentionally refactor the surrounding flow.
