Each cassette and channel carries a durable human-readable identity, threshold specification, calibration lot, installation state, and finite exposure capacity. The chemical or mechanical transition is irreversible and readable without power, software, networking, or a database.

The transformed cassette is retained under a defined evidentiary horizon as the primary physical witness.
