Use live maintenance sessions, durable capacity reservations and streamed SHA-bound ZIP uploads. An ordinary capped import worker validates stored/deflated v1/v2 packages, persists immutable unpublished candidates and finite audit events, and recovers or releases capacity after interruption and expiry.
Validate actual PG/HTTP/worker/storage fault paths in an isolated capped VM (2 passed, 0 skipped), reuse unchanged actual migration roundtrip evidence, and pass affected backend/architecture checks plus the prior full engineering checks.
