Scene.duration_sec was NULL for ~74% of playable scenes (tube duration lives on
playback_source, never propagated to Scene), so the mobile min_duration_sec=60 filter
(Scene.duration_sec >= 60; NULL fails) silently hid them — surfaced as '119 in favorites,
14 after entering the performer' (Safira Yakkuza).
- resolver: _effective_duration() falls back to max live playback_source duration when the
connector provides no scene-level duration (forward fix, used in create + update).
- scripts/backfill_scene_duration_from_playback.py: one-off idempotent backfill (recovered
204,014 scenes).
- taxonomy_counts: scene_count now counts playable AND duration_sec >= 60, matching the
always-60s-filtered scene lists, so favorites/performer/studio/tag badges agree with what
the scene screen actually shows (Safira: 39 == 39).
