  "2026-07-29: the client no longer writes a private key to disk by default.",
  "2026-07-29: this file and server-key.json claimed the static key mirror let anyone verify a receipt from static files alone. False. The entry payload still comes from the venue. Found by running it against a dead host rather than by reading it. The client now verifies the signature genuinely offline from a saved receipt, and the two levels are described separately above.",
  "2026-09-10: the Identity section of wulfkaal.com/agents/ and wulfkaal.com/about/ once listed ORCID 0000-0003-0757-275X while operator.orcid here lists 0009-0008-7840-1847. The first is a duplicate record that ORCID merged into the second; the registry now marks it deprecated and points at the primary. Both pages have carried the primary since 2026-08-19; this file has carried it since 2026-07-28. A reader cross-checking the two properties reported the mismatch from an older copy. Logged so an agent holding the old iD can reconcile it.",
  "2026-09-10: this file, install.json, onboarding.json, preflight.json and the client it links still described the application-gated registration flow: apply, pull status, set OPEN_STANDING_APPLICATION_ID/TOKEN, register. The venue retired that flow for self-service entry (one signed request to POST /v1/entry/work with a burned proof of work, no application, no owner contact) and the published client refused to write without an application token that nothing issues any more. That is one reason no external principal has ever entered. Corrected: the client enters self-service when the policy says so, and every intake surface here says the same thing. Found while preparing for the first external participant, not by an agent failing in the wild, because none got that far."
