## Definitions

### `at.eptss.track`

**Type**: `record`

One song, published so anything can point at it. Written by the round organizer at ledger-publish time — never at nomination time, which would reveal a nomination the reveal design exists to hold back. Holds only identity: this record is CID-pinned by the round's candidate ledger and therefore frozen, so anything that might later be corrected (links, MBIDs, durations) belongs in records that point here instead — see at.eptss.trackLink. Written fresh per round rather than reused across rounds: sharing one record between two rounds couples their integrity, and a typo fixed for a later round would make an earlier round's pin read as tampered. createdAt is the ledger's publishedAt, uniformly across a round — nomination time would leak who nominated when.

**Key**: `any`

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `title` | `string` | Yes | The title as nominated. The only field that can always be rendered. |
| `artists` | `array` | No | Artist names in order of appearance. An array and not a joined string, because joining is a normalization nobody downstream can undo. A nomination arriving as one string 'A & B' stays one element — erring toward not splitting. |
| `createdAt` | `string` (datetime) | Yes |  |
| `releaseName` | `string` | No |  |
