audit_false_merges only auto-fixes n>=3 (majority disambiguates the outlier); n=2
was "needs human review" — but the merge-review UI is gone, nobody triages 500+.
Measured: of 535 n=2 duration-divergent scenes, ALL have a canonical scene.duration_sec
(TPDB/StashDB) and 531 have exactly one source matching canonical (±20%) + one >2x off
→ unambiguous false-merge. Kill the off source (works both directions since canonical is
corroborated by the matching keeper, unlike the Omar-case the n>=3 audit guards against).
Applied: 529 sources marked dead (4 ambiguous skipped). Reversible (dead_at).
