Cost class: fast. The family stops listing and resolving at once: ``GET`` answers 404, and an Extract naming it fails ``schema_not_found``. Jobs accepted before the delete keep the copy of the schema they took at accept time and finish normally; their results still name the ``schema_id`` and ``schema_version`` they used. Deleting a family that is already deleted succeeds again. Platform schemas, and another tenant's or another external account's, answer 404. ## OpenAPI ````yaml /openapi.json delete /v1/extraction-schemas/{schema_id} openapi: 3.1.0 info: description: >- Document intelligence: parse, split, classify, extract, and ground files, or build a searchable workspace.
