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.

+"""Audyt + remediacja scen "teaser-only" (data quality).
+
+Problem (bug-report 2026-06-01, scena 48d6cc6b): scena ma canonical
+`scene.duration_sec` z TPDB (prawdziwa długość studyjnej sceny, np. 22min), ale
+JEDYNE żywe playback_source to krótki tubowy teaser/klip (np. xnxx 21s). Apka
+pokazuje 22min (hero z canonical) a gra 21s → mylące "22m a wideo <1m".
+
+Fix: gdy WSZYSTKIE żywe źródła sceny są znikomą częścią canonical, scena nie ma
+realnego playbacku — oznaczamy te źródła `dead_at` → scena traci żywe źródła →
+`has_playback=false` → ukryta (zgodnie z polityką orphanów: nie pokazujemy scen
+których nie da się realnie obejrzeć).
+
+Konserwatywne guardy (minimalizują fałszywe ukrycia):
+- canonical (scene.duration_sec) musi być > MIN_CANON (znamy prawdziwą długość)
+- WSZYSTKIE żywe źródła muszą mieć ZNANĄ duration (n_live == n_with_duration) —
+  źródło bez duration mogłoby być pełną sceną, więc wtedy pomijamy
+- nawet NAJDŁUŻSZE żywe źródło < RATIO * canonical (czyli żaden nie jest pełny)
+
+Reversible (dead_at, NIE delete). Domyślnie dry-run; --yes zapisuje.
+
+Uruchomienie:
+  python -m scripts.audit_teaser_only            # dry-run (podsumowanie)
+  python -m scripts.audit_teaser_only --list 30  # + lista scen
+  python -m scripts.audit_teaser_only --yes      # wykonaj
