The store reads and writes the Go on-disk format (it opens the oracle's fixture vault). Object I/O runs on one bounded worker pool with eight reusable cleared buffers; sequential and parallel runs produce identical bytes under seeded test randomness. Extraction publishes with RENAME_NOREPLACE/link and only after full authentication; failed or after-publish writes keep crash-safe ordering. Co-Authored-By: Claude <noreply@anthropic.com>
