## Commands
|
||||
|
||||
### Backend (run from `backend/`)
|
||||
All test, build, and package-manager commands run **inside Docker** — never on the host. See the memory note: "Testing inside Docker only".
|
||||
|
||||
### Migrations (run in Docker)
|
||||
|
||||
```bash
|
||||
# Install

## Architecture
|
||||
|
||||
### Request flow
|
||||
|
||||
```
|
||||
Browser → Vite dev server (:5173)
|
||||
/api/* → proxy → FastAPI (:8000)
|
||||
→ router → dependency injection (get_db, get_current_user)
|
||||
→ SQLAlchemy async session → PostgreSQL
|
||||
Browser (:5173 dev / :80 prod)
|
||||
│
|
||||
└── Vite dev proxy / nginx
|
||||
│
|
||||
└── /api/* ──→ backend:8000 (FastAPI)
|
||||
│
|
||||
┌───────────────┼───────────────────┐
|
||||
/auth /admin /documents/*
|
||||
/users /groups /documents/categories/*
|
||||
/profile /settings
|
||||
/services │ │
|
||||
JSON volume proxy (injects x-user-id)
|
||||
(/config) │
|
||||
doc-service:8001
|
||||
│
|
||||
ai-service:8010
|
||||
(classify, chat)
|
||||
```
|
||||
|
||||
### Backend layout
|
||||
|
||||
- `app/main.py` — FastAPI app, CORS, router registration
|
||||
- `app/core/config.py` — all settings via `pydantic-settings` (reads `.env`)
|
||||
- `app/core/security.py` — password hashing and JWT encode/decode
|
||||
- `app/database.py` — async engine, `AsyncSessionLocal`, `Base` (all models inherit from here)
|
||||
- `app/models/` — SQLAlchemy ORM models; import them all in `__init__.py` so Alembic detects them
|
||||
- `app/schemas/` — Pydantic request/response models (separate from ORM models)
|
||||
- `app/routers/` — one file per resource; mount in `main.py`
|
||||
- `app/deps.py` — FastAPI dependencies: `get_current_user` validates JWT and returns `User`
|
||||
|
||||
### Frontend layout
|
||||
|
||||
- `src/api/client.ts` — single Axios instance; all API calls live here, token injected via interceptor
|
||||
- `src/hooks/useAuth.ts` — token state (localStorage), `login`, `logout`; consumed by pages and `App.tsx`
|
||||
- `src/pages/` — one file per route; data fetching via TanStack Query
|
||||
- `src/App.tsx` — route tree; `PrivateRoute` wrapper redirects to `/login` when no token
|
||||
|
||||
### Auth flow
|
||||
|
||||
1. `POST /api/auth/login` returns a JWT bearer token
|
||||
2. Token stored in `localStorage`, attached to every request by the Axios interceptor
|
||||
3. Protected routes call `GET /api/users/me`; `get_current_user` dep validates the token on the server
|
||||
1. `POST /api/auth/login` → RS256 JWT (8 h), stored in `localStorage`
|
||||
2. Axios interceptor injects `Authorization: Bearer {token}` on every request
|
||||
3. `get_current_user` dep validates token on every protected route
|
||||
4. Admin routes additionally check `user.is_superuser`; return 404 (not 403) if not admin
|
||||
|
||||
## STATUS.md workflow
|
||||
---
|
||||
|
||||
Every directory that contains runnable code, a feature service, or significant logic has a `STATUS.md` file. These files are the canonical **resume point** for development — they describe what the component is, what it currently does, its limitations, and what is planned next.
|
||||
## Database Models
|
||||
|
||||
### At the start of every conversation

## Security Standards
|
||||
|
||||
These standards are **non-negotiable**. Every change must comply.
|
||||
|
||||
### JWT
|
||||
|
||||
- **Algorithm**: RS256 (4096-bit RSA key pair, generated by `scripts/generate_jwt_keys.py`)
|
||||
- **Keys**: PEM-encoded in `backend/.env` as `JWT_PRIVATE_KEY` / `JWT_PUBLIC_KEY` (gitignored)
|
||||
- **Expiry**: 8 hours (`EXPIRE_MINUTES=480`) — never set longer; no refresh tokens
|
||||
- **Claims**: `{sub: user_id, exp, iat}` — user_id is a UUID string
|
||||
- **Validation**: `decode_access_token()` in `core/security.py`; called by `get_current_user`
|
||||
- **Never**: set algorithm to `"none"`, disable `verify_exp`, or hardcode secrets in code
|
||||
|
||||
### Password hashing
|
||||
|
||||
- **Algorithm**: bcrypt, **13 rounds** (`bcrypt.gensalt(rounds=13)`)
|
||||
- **Timing**: ~300 ms per hash (intentional brute-force resistance)
|
||||
- **Never** use MD5, SHA1, or plain SHA256 for password storage
|
||||
|
||||
### Password policy (enforced in `UserCreate` schema)
|
||||
|
||||
All of the following must pass:
|
||||
- ≥ 8 characters
|
||||
- ≥ 1 uppercase (A–Z)
|
||||
- ≥ 1 lowercase (a–z)
|
||||
- ≥ 1 digit (0–9)
|
||||
- ≥ 1 special character: `!@#$%^&*()\-_=+[]{}|;:'"<>?/\`~`
|
||||
- No common words (password, secret, login, admin, test, qwerty, welcome, …)
|
||||
|
||||
### Input sanitization
|
||||
|
||||
Every user-supplied string stored in the database **must** pass through `core/sanitize.py`:
|
||||
|
||||
```python
|
||||
sanitize_str(value, max_len=255)
|
||||
# → strips whitespace; rejects null bytes (\x00); rejects control chars
|
||||
# (0x01–0x1F, 0x7F except \t \n \r); enforces max_len; returns None for ""
|
||||
|
||||
normalize_email(value) # lowercase + strip
|
||||
validate_phone(value) # sanitize_str(max=20) + regex ^\+?[\d\s\-()\[\]]{7,20}$
|
||||
validate_date_of_birth(v) # must be ≥ 1900, not future
|
||||
```
|
||||
|
||||
Apply via Pydantic `@field_validator` on all request schemas.
|
||||
|
||||
### XSS prevention
|
||||
|
||||
- React JSX text interpolation (`{value}`) is HTML-escaped by the DOM renderer — **never** use `dangerouslySetInnerHTML` with user-supplied content.
|
||||
- Server-side `sanitize_str` provides defense-in-depth (control char stripping, max length).
|
||||
|
||||
### SQL injection prevention
|
||||
|
||||
- Use SQLAlchemy ORM (bound parameters) — **never** raw SQL strings.
|
||||
- If `text()` is needed, use `bindparam()` for all user-supplied values.
|
||||
- **Never** use f-strings, `.format()`, or `%`-formatting for SQL.
|
||||
|
||||
### Admin route security
|
||||
|
||||
- Use `get_current_admin` dependency (checks `is_superuser`).
|
||||
- Return **404** (not 403) for unauthorized access — hides both endpoint existence and permission model.
|
||||
|
||||
### Network isolation
|
||||
|
||||
- `backend-net`: all containers except frontend; not reachable from host in prod.
|
||||
- `frontend-net`: only frontend; single host port (80 prod / 5173 dev).
|
||||
- DB, backend, doc-service, ai-service have **no** host port bindings in prod.
|
||||
|
||||
### Pre-commit security hook
|
||||
|
||||
`.githooks/pre-commit` runs `scripts/security_check.py` on every staged commit. It blocks commits that contain:
|
||||
|
||||
1. Hardcoded credentials / private keys / AWS creds
|
||||
2. `eval()`, `exec()`, `shell=True`, `pickle.loads()`, `yaml.load()` without SafeLoader
|
||||
3. MD5, SHA1, DES, `random.random()` / `random.randint()` for security use
|
||||
4. SQL f-strings / format strings / concatenation passed to `execute()`/`query()`
|
||||
5. JWT algorithm `"none"`, `verify_exp=False`, expiry > 9999 min, hardcoded secrets
|
||||
6. `debug=True`, `print()` with passwords
|
||||
7. `bandit` static analysis failures
|
||||
|
||||
**Never** bypass with `--no-verify` unless explicitly instructed by the user.
|
||||

|
||||
|
||||
## Frontend Patterns & Conventions
|
||||
|
||||
### API client (`src/api/client.ts`)
|
||||
|
||||
Single Axios instance — **all** API calls live here, nowhere else:
|
||||
|
||||
```typescript
|
||||
const api = axios.create({ baseURL: "/api" });
|
||||
api.interceptors.request.use((config) => {
|
||||
const token = localStorage.getItem("token");
|
||||
if (token) config.headers.Authorization = `Bearer ${token}`;
|
||||
return config;
|
||||
});
|
||||
```
|
||||
|
||||
Adding a new API call:
|
||||
1. Define a TypeScript interface for the response if it's new.
|
||||
2. Add a named export function (`getX`, `createX`, `updateX`, `deleteX`).
|
||||
3. Use `api.get<T>(...)`, `api.post<T>(...)`, etc.; always `.then((r) => r.data)`.
|
||||
|
||||
### TanStack Query conventions
|
||||
|
||||
**Query keys** (flat arrays, lowercase):
|
||||
```typescript
|
||||
["me"] // current user
|
||||
["services"] // service health list
|
||||
["dashboard-prefs"] // user dashboard preferences
|
||||
["categories"] // document categories
|
||||
["documents", params] // document list (params object for cache isolation)
|
||||
["document", id] // single document
|
||||
```
|
||||
|
||||
**Mutation pattern**:
|
||||
```typescript
|
||||
const mutation = useMutation({
|
||||
mutationFn: apiFunction,
|
||||
onSuccess: () => {
|
||||
queryClient.invalidateQueries({ queryKey: ["affected-key"] });
|
||||
// additional side effects (close dialog, reset form, etc.)
|
||||
},
|
||||
});
|
||||
// Usage:
|
||||
mutation.mutate(data);
|
||||
mutation.isPending // show spinner / disable button
|
||||
mutation.isError // show error message
|
||||
```
|
||||
|
||||
**Polling**:
|
||||
```typescript
|
||||
useQuery({ queryKey: ["services"], queryFn: getServices,
|
||||
refetchInterval: 30_000, refetchIntervalInBackground: true });
|
||||
```
|
||||
|
||||
### Route guards
|
||||
|
||||
```typescript
|
||||
// PrivateRoute — redirect to /login if no token
|
||||
// AdminRoute — redirect to /login if no token OR not admin
|
||||
// (waits for getMe() query to avoid flash; uses 404 semantics)
|
||||
```
|
||||
|
||||
### Component patterns
|
||||
|
||||
- Functional components only.
|
||||
- Local `useState` for UI-only state (edit mode, pending values, open/closed).
|
||||
- Server state via `useQuery` / `useMutation` — no duplicated local copies.
|
||||
- `cn()` from `lib/utils.ts` for conditional Tailwind classes.
|
||||
- `lucide-react` for all icons.
|
||||
- Never use `dangerouslySetInnerHTML` with user-supplied content.
|
||||
|
||||

|
||||
|
||||
## Naming & Code Conventions
|
||||
|
||||
### Database
|
||||
|
||||
- **Tables**: lowercase, plural, snake_case (`users`, `group_memberships`, `document_category_assignments`)
|
||||
- **Columns**: lowercase, snake_case
|
||||
- **ORM models**: PascalCase, singular (`User`, `Group`, `GroupMembership`, `Document`)
|
||||
- Primary keys: `id` (String UUID, auto-generated)
|
||||
- Timestamps: `created_at` / `updated_at` / `joined_at` / `processed_at` — always timezone-aware
|
||||
|
||||
### Pydantic schemas
|
||||
|
||||
| Suffix | Purpose |
|
||||
|--------|---------|
|
||||
| `Create` | POST request body (user-supplied input) |
|
||||
| `Update` | PATCH request body (partial update) |
|
||||
| `Out` | API response (safe subset of model) |
|
||||
| `AdminOut` | Extended response for admin endpoints |
|
||||
| `Read` | GET response (same as `Out`, used for profiles) |
|
||||
|
||||
Always set `model_config = {"from_attributes": True}` on response schemas.
|
||||
Use `validation_alias` when the ORM field name differs from the JSON key (e.g., `is_superuser` → `is_admin`).
|
||||
|
||||
### HTTP status codes
|
||||
|
||||
| Code | Use |
|
||||
|------|-----|
|
||||
| 200 | Successful GET / PATCH / PUT |
|
||||
| 201 | Successful POST that creates a resource |
|
||||
| 202 | Accepted (async processing started, e.g., document upload) |
|
||||
| 204 | Successful DELETE or action with no response body |
|
||||
| 400 | Bad request (duplicates, invalid data beyond Pydantic) |
|
||||
| 401 | Missing / invalid JWT |
|
||||
| 404 | Not found **and** admin routes when not admin |
|
||||
| 413 | Payload too large (file exceeds limit) |
|
||||
| 415 | Unsupported media type (not a PDF) |
|
||||
| 422 | Pydantic validation failure (FastAPI default) |
|
||||
| 502 | Downstream service unreachable |
|
||||
| 503 | Service unavailable (queue stopped, AI error) |
|
||||
| 504 | Gateway timeout |
|
||||
|
||||
### Backend code style
|
||||
|
||||
- Async/await for **all** I/O (DB, HTTP, file).
|
||||
- `raise HTTPException(status_code=..., detail="...")` for all errors.
|
||||
- Response models always declared in route decorator: `@router.get("/path", response_model=XOut)`.
|
||||
- Background tasks via `BackgroundTasks` param; tasks open their own `AsyncSessionLocal` session.
|
||||
- Commit + refresh pattern after mutations:
|
||||
```python
|
||||
await db.commit()
|
||||
await db.refresh(obj)
|
||||
```
|
||||
|
||||
### Frontend code style
|
||||
|
||||
- TypeScript strict mode — no `any`.
|
||||
- API response types inferred from interfaces in `client.ts` only.
|
||||
- Error messages displayed inline (no alert); loading shown as disabled state or "…" text.
|
||||
- All user-facing text: safe via React JSX rendering (not innerHTML).

## Workflows
|
||||
|
||||
### STATUS.md workflow
|
||||
|
||||
Every directory with runnable code has a `STATUS.md`. These are the canonical **resume point** for each session.
|
||||
|
||||
**At the start of every conversation:**
|
||||
1. Read the `STATUS.md` for every directory you will touch.
|
||||
2. If the file does not yet exist for a directory you are working in, create one using the structure below.
|
||||
2. If it does not exist for a directory you are working in, create it using the structure below.
|
||||
|
||||
This applies equally to subagents — always read the relevant `STATUS.md` before starting work.
|
||||
This applies equally to subagents.
|
||||
|
||||
### After making changes
|
||||
|
||||
Update any `STATUS.md` that is affected:
|
||||
- Add new endpoints / models / routes to the **Current functionality** tables.
|
||||
**After making changes**, update affected `STATUS.md` files:
|
||||
- Add new endpoints / models / routes.
|
||||
- Move completed items off the **Future work** checklist.
|
||||
- Add new items to **Known limitations** or **Future work** as appropriate.
|
||||
- Keep the **What it is** summary accurate (port, DB, storage, etc.).
|
||||
|
||||
### STATUS.md structure
|
||||
|
||||
Each file must contain these sections (add/remove sub-sections as needed):
|
||||
- Add new items to **Known limitations** or **Future work**.
|
||||
- Keep the **What it is** summary accurate.
|
||||
|
||||
**Structure:**
|
||||
```markdown
|
||||
# <Service Name> — Status
|
||||
|
||||
## What it is
|
||||
One paragraph: purpose, internal port, database/storage, how traffic arrives.

|
||||
|
||||
Always run `git push` immediately after every `git commit`.
|
||||
|
||||
## Infrastructure change protocol
|
||||
|
||||
After **any** change to Dockerfiles, `docker-compose*.yml`, `nginx.conf`, setup scripts, or installation / usage procedures:
|
||||
|
||||
1. **Update `README.md`** — keep the Containers table, ports, image names, and Current State section accurate.
|
||||
2. **Spin up the dev stack** and verify that login and registration work end-to-end:
|
||||
```bash
|
||||
docker compose -f docker-compose.yml -f docker-compose.dev.yml up --build
|
||||
```
|
||||
3. **Spin up the prod stack** and run the same checks:
|
||||
```bash
|
||||
docker compose up --build -d
|
||||
```
|
||||
4. Confirm each container is running as a non-root user (`docker inspect <container> --format '{{.Config.User}}'`).
|
||||
5. **Tear down after testing** — stop and remove all containers, networks, and volumes:
|
||||
```bash
|
||||
docker compose down --volumes --remove-orphans
|
||||
# or for dev stack:
|
||||
docker compose -f docker-compose.yml -f docker-compose.dev.yml down --volumes --remove-orphans
|
||||
```
|
||||
|
||||
## Security hook
|
||||
|
||||
A pre-commit hook lives in `.githooks/pre-commit` and runs `scripts/security_check.py` inside a Docker container. It is registered via `git config core.hooksPath .githooks` (already set in this repo).
|
||||
|
||||
The hook checks staged files for:
|
||||
- Hardcoded credentials / secrets
|
||||
- Dangerous patterns (`eval`, `exec`, `shell=True`, `pickle`)
|
||||
- Weak cryptography (MD5, SHA1, DES)
|
||||
- SQL injection risk
|
||||
- Debug flags left in code
|
||||
- `bandit` static analysis on all Python files
|
||||
|
||||
New clones must run `git config core.hooksPath .githooks` to activate the hook.
|
||||
|
||||
## Changelog convention
|
||||
|
||||
Every time files are added or modified, append an entry to the relevant file in `changelog/` (one file per date, named `YYYY-MM-DD_<slug>.md`). If a file for today already exists, append to it rather than creating a new one.
|
||||
Every time files are added or modified, append to `changelog/YYYY-MM-DD_<slug>.md`. If today's file exists, append; otherwise create new.
|
||||
|
||||
Each entry must include:
|
||||
- A heading with the date and a short description
|
||||
- A heading with date and short description
|
||||
- `**Timestamp:**` in ISO-8601 format
|
||||
- A **Summary** sentence
|
||||
- A **Files Added / Modified / Deleted** list with one-line descriptions
|
||||
|
||||
The `README.md` **Current State** section should be kept up to date whenever significant features are added or removed.

### Adding a new resource (checklist)
|
||||
|
||||
1. Add ORM model in `backend/app/models/`, import it in `models/__init__.py`
|
||||
2. Run migration: `docker compose exec backend alembic revision --autogenerate -m "add <resource>"` then `alembic upgrade head`
|
||||
3. Add Pydantic schemas in `backend/app/schemas/`
|
||||
4. Add router in `backend/app/routers/`, mount it in `main.py`
|
||||
5. Add API function(s) to `frontend/src/api/client.ts`
|
||||
6. Add page component in `frontend/src/pages/`, register route in `App.tsx`
|
||||
7. Update `STATUS.md` for affected services
|
||||
8. Add changelog entry

|
||||
|
||||
1. Add ORM model in `app/models/`, import it in `app/models/__init__.py`
|
||||
2. Run `alembic revision --autogenerate -m "add <resource>"` + `alembic upgrade head`
|
||||
3. Add Pydantic schemas in `app/schemas/`
|
||||
4. Add router in `app/routers/`, mount it in `app/main.py`
|
||||
5. Add API function(s) to `src/api/client.ts`, add page/component, register route in `App.tsx`
|
||||
Always run `git push` immediately after every `git commit`.

```bash
|

### Security hook
|
||||
|
||||
`.githooks/pre-commit` (registered via `git config core.hooksPath .githooks`). Runs `scripts/security_check.py` in Docker. New clones must run:
|
||||
```bash
|
||||
git config core.hooksPath .githooks
|
||||
```
|
||||
|
||||
See **Security Standards → Pre-commit security hook** for the full list of checks.
|
||||
|
||||
**Never** bypass with `--no-verify`.
