thepraandClaude Opus 5.5 b9286c2c6e Deliveries refused with 409 or 422 get three tries ...

Mastodon answers 422 when two first contacts from one actor race to
create its account (ActiveRecord::RecordInvalid on the unique uri), and
409 while another worker holds its lock. A persona that followed two
Mastodon accounts at once had one Follow refused that way; the job died
on its first attempt and the persona waited on "requested" forever.
Both answers are now retried twice on the usual backoff before they
count as refusals.

Found by the town (a village of 23 accounts on seven servers).
