What sync or timing tolerance, picture-reference rule and QC check do the Netflix Live Action, Animation, 5.1 Mix Room and Secondary Audio pages (and the delivery spec the last one points to) state for dubbed dialogue, and what is absent?

No numeric sync tolerance for dubbed dialogue (frames or milliseconds) appears in the four assigned pages. The sync statements are qualitative or about equipment: the 5.1 room page requires picture displays and DAWs to be in frame-accurate sync (four named causes of drift); the Animation page asks for frame-accurate futz edits, clips "in sync", no time-stretch artifacts, 24 fps timecode (or as provided) and a programme start of 00:00:00:00 or the proxy. The archived delivery-spec page (version 5.1, 2024-08-10) adds that all audio must sync to final picture including 1 second of black either side, no extra leader, and measurable levels (-27 LKFS +/- 2 LU dialogue-gated; -2 dBFS true peak). Its only time tolerance, half a second, is for subtitle files, not audio. QC criteria are not listed on the four pages beyond rejection for tonality differences.
