bug-report 2026-06-01 (48d6cc6b): scene shows canonical duration from TPDB
(real 22min studio scene) but the only live playback_source is a short tube
teaser (xnxx 21s) → "shows 22m, plays <1m". When ALL live sources are a tiny
fraction (<15%) of a known canonical (>300s), the scene has no real playback;
mark those sources dead → scene becomes orphan → hidden (has_playback=false),
consistent with the orphan-hiding policy. Reversible (dead_at), conservative
(skips scenes with any unknown-duration or full-length live source).
Applied on prod: 182 sources dead across 174 scenes.
