# Delete a context_attachment

`DELETE /documents/{document_id}/context-attachments/{attachment_id}`

Deletes the attachment item and, if it has an associated S3 blob, the blob too. Idempotent at the HTTP layer: a delete on a non-existent attachment returns 404 with a stable error code so the integrator can choose to treat it as success.

**Snapshot semantics:** if extraction is in flight against this attachment, the in-memory snapshot in the worker is unaffected — the in-flight job completes against the pinned payload, and the resulting facts carry the now-dead attachment_id in `Fact.context_attachment_ids_used`.

## Path parameters

- `document_id` string, uuid, required
- `attachment_id` string, uuid, required

## Response `204`

Attachment deleted

## Other responses

- `404` — Attachment not found
