User, after a live run: "First pass runs its own FULL schedule. Then 2nd pass begins.
If I want to stop 1st pass earlier - I remove sigmas from schedule... 'Continue from'
is ONLY relevant in our shifting technique which is a separate entity."
Correct, and the cut was mine, not theirs. I carried anchor_shift's cut/restart
semantics into a feature that has no use for them. Consequences they hit on the rental:
- Steps. Pass 1 was cut at the second schedule's first sigma, so a 9-step main plus a
4-step second pass ran 3+4=7, not 13. They noticed the missing steps.
- Distortion. With the cut, the between-pass operation ran on a MID-TRAJECTORY latent,
so "sharpen" was sharpening the noise still in it. It only makes sense on a finished
clip.
Now: pass 1 runs the main schedule in full, exactly as written. The operation runs on
that finished clip. Pass 2 runs second_pass_sigmas in full, exactly as written, entering
the way any img2img refine does — comfy's ordinary CONST scaling on a clean latent, so
continue_from_state stays off. Total steps are the two schedules added up. To make pass 1
shorter, shorten the main schedule.
second_pass_sigma and second_pass_restart_sigma are deleted outright: with both schedules
run as written there is nothing to cut and nothing to continue from. The second schedule's
first sigma is now simply the strength dial, the way it is in every img2img refine.
_second_pass_plan is replaced by _second_pass_schedule, which only validates.
Also reported: "I have only sharpening enabled but log tells me upsampling is enabled as
well." The load line printed "[FunPackSceneChain] segmented detailing upsampler: ..."
regardless of which feature pulled it in, and sharpen legitimately loads that model —
so a sharpen-only run announced a feature that was off. Now "latent upsampler loaded".
Kept: the malformed-schedule refusals (ascending, or not ending at 0) — both are silent
in the output rather than loud at runtime, which is how the distorted run read.
tests/test_second_pass.py rewritten around the corrected shape, including that a 9-step
main plus a 4-step second pass is 13. Suites at baseline: 22 pre-existing failures, 467
passing. Verified live that typing a schedule sets second_pass with no cut knob leaking.
