Failure policy: a failed preview gets one delayed retry (about 50 s). If a
|
||||
batch is two-thirds suspect failures, the cooldown doubles (60 s floor) and
|

the retries run before the next batch. Rows that still fail are left
|

unverified and skipped by later passes; the recovery task above retries
|

Discord-CDN ones on demand.
