## Definitions

### `ink.branchline.publishSeed`

**Type**: `procedure`

Gift a seed. The caller must be signed in and must be the grantee of `grantor`; publishing passes that seed's planting right on to `grantee` as a new child seed. The AppView writes an ink.branchline.seed record to the caller's PDS and mirrors it into the local read cache. Root (grantor-less) seeds are not created through this endpoint — they are authored only by the branchline.ink repo.

#### Input

**Encoding**: `application/json`

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `grantee` | `string` (did) | Yes | DID of the new grantee receiving the gift. |
| `grantor` | `string` (at-uri) | Yes | AT-URI of the seed the caller currently holds as grantee. |
| `expiresAt` | `string` (datetime) | No | Optional expiry for the new grant. Must not extend past the grantor chain's earliest expiry. |

#### Output

**Encoding**: `application/json`

| Property | Type | Required | Description |
|----------|------|----------|-------------|
| `cid` | `string` (cid) | Yes |  |
| `uri` | `string` (at-uri) | Yes |  |

#### Errors

- **Unauthorized**: The caller is not signed in.
- **GrantorNotFound**: The grantor seed does not exist in the AppView.
- **NotGrantee**: The caller is not the grantee of the grantor seed.
- **GrantorExpired**: The grantor seed's expiry has passed.
- **GrantorAlreadyGranted**: The grantor seed has already been granted to another recipient.
