Backend:
- New ivanti_finding_overrides table (finding_id, field, value) with
UNIQUE(finding_id, field) — same survival-across-sync pattern as notes
- PUT /api/ivanti/findings/:id/override (editor/admin only) — saves or
clears a field override; empty value = revert to Ivanti
- Overrides merged into findings at read time via readOverrides()
- Whitelisted fields: hostName, dns
Frontend:
- OverrideCell component — click to edit inline (editor/admin only),
Enter/blur to save, Escape to cancel
- Amber dot indicator on cells with an active local override
- Hover tooltip shows original Ivanti value when overridden
- RotateCcw button reverts cell back to Ivanti value in one click
- canWrite() gating via useAuth — viewers see the value, can't edit
