Publish a catalogue Look revision

Makes an approved look revision the one new try-ons render, at the expected_generation you read (409 GENERATION_CONFLICT otherwise). A revision that is not approved answers 409 REVISION_NOT_APPROVED; a retired look 409 LOOK_RETIRED. Every dependency the revision pins must still be available: a pinned variant that is retired, or a pinned profile that is withdrawn, answers 400 INVALID_REQUEST with look_dependency_unavailable at applications[i], and nothing moves. Publishing an earlier approved revision is rollback. Send an Idempotency-Key: a retry with the same key and the same request answers the first response, byte for byte, with Idempotency-Replayed: true, so a response you did not receive is safe to retry. Requires the catalogue.publish scope, which your account operator provisions; no other catalogue scope implies it. Served only where the catalogue is enabled for your environment.
