Two releases published together (inbuxa-server's main and release/2026 on 2026-10-29) reached the forum 14 s apart; Discourse answered the second with 429 and the job failed. On 429 the script now waits the wait_seconds Discourse gives (15 s when it gives none, 60 s at most) and tries again, three times in all. A retry can't double-post: the external_id makes a repeat a 422, which is already treated as announced.
