## Provenance Block Format

Each playlist item now includes:

```json
{
  "provenance": {
    "type": "offChainURI",
    "contract": {
      "chain": "other",
      "uri": "https://aesthetic.computer/$code"
    }
  }
}
```

### Example from Colors playlist:
```json
{
  "title": "aliceblue",
  "source": "https://aesthetic.computer/aliceblue?tv=true&density=5",
  "provenance": {
    "type": "offChainURI",
    "contract": {
      "chain": "other",
      "uri": "https://aesthetic.computer/aliceblue"
    }
  }
}
```

## Scripts Updated

### Playlist Generation Scripts
- ✅ `feed/create-top-kidlisp-playlist.mjs` - Now includes provenance
- ✅ `feed/create-kidlisp-colors-playlist.mjs` - Now includes provenance
- ✅ `feed/create-kidlisp-chords-playlist.mjs` - Now includes provenance

### Update Scripts
- ✨ `feed/update-existing-playlists.mjs` - Updates existing playlists with provenance
- ✨ `feed/update-kidlisp-playlists-simple.mjs` - Simple regeneration wrapper
- ✨ `feed/regenerate-kidlisp-playlists.mjs` - Full regeneration with delete

### Changes Made
- Removed `node-fetch` import (using native fetch in Node 22)
- Fixed provenance schema to include required `chain` field
- Used `'other'` for chain type (offchain KidLisp pieces)

---

## Verification

Test any playlist item:
```bash
curl -s https://feed.aesthetic.computer/api/v1/playlists/2680b102-04ee-47b5-b7d7-f814094695e7 \
  | jq '.items[0].provenance'
```

Expected output:
```json
{
  "type": "offChainURI",
  "contract": {
    "chain": "other",
    "uri": "https://aesthetic.computer/aliceblue"
  }
}
```

---

## API Authentication

The production API uses Bearer token authentication stored as a Cloudflare Workers secret:
- **Secret Name:** `API_SECRET`
- **Location:** Cloudflare Workers environment (not in git)
- **Local Copy:** `aesthetic-computer-vault/feed/.env`

---

## Future: On-Chain Migration

When KidLisp pieces are minted as Tezos FA2 tokens, update provenance to:

```json
{
  "type": "onChain",
  "contract": {
    "chain": "tezos",
    "standard": "fa2",
    "address": "KT1...",
    "tokenId": "42",
    "uri": "ipfs://..."
  }
}
```
