…ptember 7 capture The page reported witness_time_established and grade_cryptographically_bound as false for that capture without saying why they stay false. The witness signature covers the protected header the fields are read from, so a receipt carrying a CWT iat or a signed grade is a separately signed receipt. A witness shipping support for them changes a later receipt and leaves the archived one alone. Stated that way the line has no shelf life and needs no pass at deploy time.

The registry page reported
witness_time_establishedandgrade_cryptographically_boundas false for the September 7 capture without saying why they stay false, which reads as a line with a shelf life once the witness operator ships support for the two fields.The witness signature covers the protected header the fields are read from, so a receipt carrying a CWT
iator a signed grade is a separately signed receipt. That receipt's header decodes to{1: -8, 395: 1}, algorithm and tree profile only.Stated that way the line needs no pass at deploy time.
Matches agentrust-io/trace-registry#72, which makes the same correction in the README, LIMITATIONS and the evidence packet.
