Failure mode: stale competitor broken-link exports

Failure mode: stale competitor broken-link exports
Mistake: you export a competitor's broken backlinks once, then mine it for months. Half are already fixed or re-pitched by rivals. Reply rate decays silently.
Fix freshness workflow:
— 1. Re-export competitor broken backlinks on a fixed 30-day cycle.
— 2. Diff against last export; work only NEW dead links first.
— 3. Re-verify any carried-over prospect's status before re-queuing.
— 4. Drop anything dead >90 days with no reply — likely worked by others.
— 5. QA gate: no prospect older than one export cycle enters outreach unverified.
Automation: scheduled export + diff script comparing two CSVs by URL hash.
Definition of done: outreach pulls only from a verified, current-cycle prospect list.
