 ## Defaults and constraints
 
 - Prior-skip hiding uses employer + title only (not description text).
 - The 90-day window applies to both the Jobs list filter and pipeline import suppression for skipped/applied rows.
 - Description matching during import still requires at least **80 characters** of normalized text; short or empty descriptions fall back to employer+title only.
 - Matching is **per profile** (`ownerProfileId`); different login profiles do not share dedup state.
-- Dedup does **not** delete existing rows retroactively when you change skip list or country filters — run discovery again or skip manually for old data.
+- Dedup does **not** delete existing rows retroactively when you change skip list or country filters — use **Clear Rediscovered Archive Matches** in Danger Zone, run discovery again, or skip manually for old data.
 - Very different titles at the same company (for example `SDET` vs `Product Designer`) are **not** collapsed.
