Agent lists now backfill last-used times from old sessions so ordering makes sense.
What's wrong with this entry?
Anonymous. No account, no email.
What
Agents that have never been used since last-used tracking was added no longer sort as if they were brand new. A backfill pass walks existing sessions and, for any agent with no recorded last-used time, adopts that session's creation time. The default agent is skipped.
Evidence

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
