UPLOAD RELEASE INTEGRATION WORKSHEET Fixture scope: sequential control flow and assigned verdicts only. Identity: server upload ID, trusted tenant, immutable object generation, trusted digest. Intake: private storage, bounded transfer, validated type/size and completion evidence. Processing: authenticated worker reads exact version; policy and attempt identity recorded. Mutation: conditional state and version update is atomic. Retrieval: authorize caller then serve approved immutable version. Negative checks: obsolete positive result, current negative result, untrusted result, other tenant, duplicate completion, stalled processing and new bytes after approval. Alternate consumers: previews, conversions, email and extraction obey their own untrusted-input boundary. Capabilities: test direct quarantine access and lifetime of previously issued downloads after revocation. Execution record: identify actual object version read by worker and version returned to customer. No scanner, storage policy or concurrent transaction has been validated by the accompanying fixture.
