Attestation

This examination pack was generated by BLACKBOX on Thu, 18 Jun 2026 05:58:59 GMT. The hash chain integrity status above reflects the result of independently recomputing SHA-256 over the canonical JSON of every recorded event. The chain head d7a2d0b691739479… is the tamper-evident fingerprint of this run. Any alteration to any event — however small — will produce a different chain head that can be detected by re-running the verifier against the stored event sequence.

Faithful playback: all inputs and outputs are stored verbatim. Approximate re-execution: provider non-determinism means bit-identical replay is not claimed or guaranteed.
