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.

FrodoKEM-640-SHAKE is ported from CIRCL v1.6.4 (the RustCrypto crate
implements the incompatible ISO variant) and reproduces the reference
NIST KAT digest. ML-KEM-768 comes from RustCrypto ml-kem. Derivation,
encapsulation, implicit rejection, KEK, header MAC, header parsing,
STREAM and Argon2id key files all match vectors from the Go oracle, Go's
files decrypt in Rust, and Go decrypts Rust's.
