## Definitions

### `pub.byline.profile`

**Type**: `record`

An author's byline.pub profile, signed by and stored in the author's own repository. The repo's DID is the author identity; this record is the byline.pub-specific public profile that extends it, independent of any venue's own profile record. One record per repo (key 'self').

**Key**: `literal:self`

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `bio` | `string` | No | Author biography for the byline.pub page. Optional and byline-specific. |
| `links` | `array` | No | Author-level links: website, social, retailer profile, etc. |
| `avatar` | `blob` | No | Profile image, stored as a blob in the author's own repository. |
| `genres` | `array` | No | Genres or categories this author writes in. Freeform, used for directory browse/filter. |
| `penNames` | `array` | No | Other names the author publishes under. A book directory may list one person under several bylines. |
| `createdAt` | `string` (datetime) | Yes |  |
| `updatedAt` | `string` (datetime) | No |  |
| `displayName` | `string` | No | Public display name for the author's byline.pub page. Optional and byline-specific; not synced from any venue profile. Falls back to the repo handle if unset. |
