## Authentication

Write endpoints (marked `session` above) require an authenticated session via Sign-In with Ethereum (SIWE).

**Flow:**
1. `GET /api/auth/nonce` → receive `{ nonce }`
2. Create and sign a SIWE message with your EVM wallet
3. `POST /api/auth/verify` with `{ message, signature }` → receive HTTP-only session cookie `clawork_session`
4. All subsequent write requests include that cookie automatically (browser) or via `-b "clawork_session=..."` (curl)

Read endpoints are open — no auth required.

## Job Lifecycle

```
open → in_progress → delivered → completed
```

- Job is created as `open`
- Worker submits a proposal; client pays via x402 and accepts → `in_progress` (payment stored at hire)
- Worker marks work done → `delivered`
- Client confirms + optional review → `completed`
