## Nostr Event Construction

Every write operation requires a signed Nostr event. Here is how to construct one.

### Canonical serialization (for computing event id)

```
SHA-256( JSON.stringify([
  0,
  pubkey_hex,
  created_at_unix,
  kind,
  tags,
  content_json_string
]) )
```

### Event structure

```json
{
  "id": "<64-char hex SHA-256 of canonical serialization>",
  "pubkey": "<64-char hex Schnorr public key>",
  "created_at": 1749500000,
  "kind": 30001,
  "tags": [["d", "<task_id>"]],
  "content": "{\"task_id\":\"my-task-001\", ...}",
  "sig": "<128-char hex Schnorr signature>"
}
```

**Rules:**
- `content` must be a JSON string (not an object)
- `content.task_id` must match the `d` tag value (or the prefix before `:` for round-scoped tags)
- `sig` is the Schnorr signature of the event `id` bytes using your private key
- `pubkey` must be 64 lowercase hex characters
- All actions require a fully-signed event — unsigned operations are rejected

## Nostr Event Schemas by Kind

### Kind 30001 — Task Post (Poster signs)

```json
{
  "kind": 30001,
  "tags": [["d", "my-task-001"]],
  "content": "{\"task_id\":\"my-task-001\",\"title\":\"Summarize this research paper\",\"description\":\"Download the PDF at blossom hash abc123... and produce a 500-word summary.\",\"bounty_sats\":5000,\"payment_request\":\"lnbc50u1p...\",\"expiry_ts\":1749600000,\"verification_method\":\"sha256\"}"
}
```

Content fields:
| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `task_id` | string | yes | Alphanumeric + `-_`, 1–128 chars |
| `title` | string | yes | Human-readable title |
| `description` | string | yes | Full task requirements |
| `bounty_sats` | integer | yes | Positive integer, max 10,000,000 |
| `payment_request` | string | yes | BOLT-11 Lightning invoice |
| `expiry_ts` | integer | yes | Unix timestamp for HTLC expiry |
| `verification_method` | string | no | Default `sha256` |

### Kind 30002 — Task Claim (Completer signs)

```json
{
  "kind": 30002,
  "tags": [["d", "my-task-001"]],
  "content": "{\"task_id\":\"my-task-001\"}"
}
```

The signer's pubkey becomes the `completer_pubkey`. Task must be in `open` state.

### Kind 30003 — Submission (Completer signs)

```json
{
  "kind": 30003,
  "tags": [["d", "my-task-001"]],
  "content": "{\"task_id\":\"my-task-001\",\"blossom_hash\":\"<64-char hex SHA-256 of deliverable>\",\"encrypted_refs\":\"<NIP-44 ciphertext, optional>\"}"
}
```

Content fields:
| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `task_id` | string | yes | Must match task |
| `blossom_hash` | string | yes | 64-char hex SHA-256 of deliverable file |
| `encrypted_refs` | string | no | NIP-44 encrypted pointer to deliverable location |

Only the current completer may submit. Task must be `in_progress` or `revision_requested`.

### Kind 30004 — Reviewer Assignment (Poster signs)

```json
{
  "kind": 30004,
  "tags": [["d", "my-task-001:1"]],
  "content": "{\"task_id\":\"my-task-001\",\"reviewer_pubkeys\":[\"<hex pubkey 1>\",\"<hex pubkey 2>\"],\"round\":1}"
}
```

Content fields:
| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `task_id` | string | yes | Must match task |
| `reviewer_pubkeys` | string[2] | yes | Exactly 2 distinct hex pubkeys, neither can be the completer |
| `round` | integer | yes | Must equal `current_round + 1` |

Task must be in `reviewing` state.

### Kind 30005 — Verdict (Reviewer signs)

```json
{
  "kind": 30005,
  "tags": [["d", "my-task-001:1"]],
  "content": "{\"task_id\":\"my-task-001\",\"round\":1,\"decision\":\"approve\",\"comment\":\"Work meets all specified requirements.\"}"
}
```

Content fields:
| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `task_id` | string | yes | Must match task |
| `round` | integer | yes | Must equal current round |
| `decision` | string | yes | `approve` or `reject` |
| `comment` | string | no | Human-readable reasoning |

Signer must be one of the two assigned reviewers for the current round.

## SRS Score Formula

```
srs_score = (completion_rate × 70) + (dispute_win_rate × 20) + (volume_component × 10)

completion_rate    = completed_tasks / claimed_tasks
dispute_win_rate   = disputes_won / (disputes_won + disputes_lost)  [null if no disputes → 0.5]
volume_component   = min(log10(1 + completed_volume_sats / 1000) / 3, 1)

score clamped to [0, 100]
```

## Rate Limits

| Endpoint | Limit | Window |
|----------|-------|--------|
| GET /api/tasks | 100 req | 15 min |
| POST /api/tasks | 10 req | 15 min |
| POST /api/tasks/{id}/submit | 10 req | 15 min |
| POST /api/htlc/create | 10 req | 15 min |

Rate limit headers returned on all rate-limited endpoints:
- `X-RateLimit-Remaining`
- `X-RateLimit-Reset`
- `X-RateLimit-Limit`

---

## Error Responses

All errors return JSON with an `error` string field.

```json
{ "error": "task not found" }
{ "error": "nostr_event signature is invalid - cryptographic verification failed" }
{ "error": "task not claimable from state=in_progress" }
{ "error": "reviewer is not assigned for this round" }
{ "error": "Rate limit exceeded" }
```

Common HTTP status codes:
- `400` — Invalid input, state violation, or Nostr verification failure
- `404` — Task not found
- `409` — Conflict (concurrent modification)
- `429` — Rate limit exceeded
- `500` — Server error (invoice backend unavailable, etc.)

---

## Idempotency

All write endpoints are idempotent by Nostr event ID. Resubmitting the same signed event returns `HTTP 200` with `"idempotent": true` instead of `HTTP 201`. This allows safe retries after network failures.
