`POST /api/v1/card-batches/{id}/printed`

Records that the sheet was rendered, stamping printed_at and incrementing print_count.

- Authentication: manager session (JWT) or API token
- Permission: `prm_cards_download` (Download / export cards)
- Risk: write
- Rate limit bucket: `t_mutate`

#### Parameters

| Name | In | Type | Required | Description |
| --- | --- | --- | --- | --- |
| `id` | path | integer | yes | Series id. |

#### Note

Print tracking is observational only and deliberately does NOT move the series status. Nothing may set status to 'printed': the till refuses to mint into any series whose status is not 'ready', so auto-stamping would silently close every printed series to counter top-ups.
