The two-pass shift regrew the frames it dropped, and the invented ending
consistently came out with worse or missing movement — not worth paying
steps for. What is left is the part that works: generate the scene exactly
as normal, anchor pinned at full strength the whole way, then cut the
opening off the finished clip. Nothing is regrown, so the scene comes out
that much shorter and the audio is cropped to match.
Six knobs collapse into one INT, cut_opening_frames (0 = off), in the
Editor under Chain Sampler ▸ Timing & Seed rather than Experimental.
Gone with the shift: the mid-schedule split, the rewind re-noise
(_renoise_to_sigma), the tail refill modes, the fresh-audio reset, and the
schedule_context/continue_from_state plumbing that existed only so a split
scene would not re-time the sampler inside each half.
second_pass is untouched — it never used any of that machinery.
