Integrity without overclaiming

Archive Integrity and Provenance Boundaries

The public integrity model for source identity, byte-level digests, provenance notes, limitations, and human review.

Archive integrity controls and boundaries

Control	What it supports	What it does not prove
Stable identifier	Consistent record reference.	Authorship, truth, or completeness.
SHA-256	Byte-for-byte comparison with the hashed file.	Authenticity, chain of custody, or admissibility.
Provenance note	The archive's documented source basis and handling.	Independent validation of every source statement.
Human-review status	Whether the public control record received the stated review.	Government, expert, or judicial approval.

Integrity controls reduce ambiguity and detect byte changes; they do not make the archive immutable or establish admissibility.
