FAULT_RETRY_LIMIT =

A non-done job status (faulted, etc.) is a transient Oxylabs-side scraper
failure, not an unreachable page — one faulted batch run marked 55
reachable Ferguson Home items "unreachable online" (2026-07-24), poisoning
the compliance report and feeding ProbeAutoSkipper. Re-submit the probe,
capped per item/day, before recording a failed probe.
