DELETE /v1/agents/:agentId/artifacts/:artifactId

Tombstones the Artifact record and enqueues durable, internally idempotent deletion of its private Storage object; Session transcripts are not rewritten. A repeated HTTP deletion returns 410 not_found because the Artifact is already tombstoned.

Response

Returns 204 No Content with an empty body.

Errors
