How to read this profile

Declared means advertised in /supported. Payment behavior is untested. No /verify, /settle or payment requests are made.

Stale retains the last positive evidence after failure or an omission. Not advertised means recently omitted, not unsupported or withdrawn. Failures break the consecutive omission count.

Bazaar declarations do not establish discovery availability. A reachable endpoint can return an invalid declaration or HTTP error.

Latest slice within 7 days / chronological

At most 100 events / 2 MiB raw bodies, newest selected first and displayed chronologically. Earlier events, even part of a check, may be excluded. This is not the full retained history. Capture timestamps are shown for each event.
