- Correction: the evidence archive presented hashes of source addresses as content hashes on four exhibits
- what was wrong
- An archive status note of 27 October 2026 said that four archived exhibits carried content hashes computed at retrieval, with the document bytes not stored. That was false. No content hash was ever computed for any of the four.
- what is true
- Each stored value is the SHA-256 of the source address, confirmed on 29 October by recomputing the hash over each address and matching all four exactly. A hash of an address establishes the identity of the address and nothing about the document: not that it existed in a given form, not that a passage was present, not that it is unchanged. The four exhibits support rows on the Agent Authorization Boundary Failure and AI Agent Runtime Compromise conditions.
- what changed
- The four exhibits are relabelled as address hash only, content not retained. The 27 October note is superseded with its original text kept. A current status line records that four exhibits are held, no document bytes are retained and no content hash exists. The dates on the exhibits are retrieval dates and are not presented as capture or verification dates.
- what did not change
- No rating, Outlook, counted set or published text. The affected rows keep their stated grades. What is withdrawn is the claim of cryptographic evidence of their content.
- control analysis
- The first exhibit's own note described its value correctly as a placeholder; a later summary upgraded all four to content hashes. The error was an over-claim introduced by a summary written over a correctly hedged original. Capture of primary documents at admission had been declared as practice on 9 October and was not being done; that gap is disclosed, not closed, by this correction.
