Three things that were each locked to one implementation detail:
- steps + schedule were a KSampler-branch feature, though every sampler here
walks a sigma list handed in from outside. They are now pass-level, so
Distilled Flow and Hybrid Euler 2S can run a named schedule (and the second
pass can be computed rather than typed) in both frontends and on the node.
- the project's Frames field snapped to the model's grid on every family. On
H3 that is required, but its arrows moved by 1 and the snap put the value
straight back; on LTX the builder rounds up by itself, so the snap only
fought the user. H3 now steps a whole 17 frames per arrow, LTX keeps what
you type and walks 8k+1 with its arrows.
- ALG lived inside the Distilled Flow step loop, so it was unreachable with a
stock KSampler. Its blurred/sharp swap is decided by the step's sigma, and
sigma is an argument of every model call, so a denoiser proxy drives it from
outside any sampler. New alg_anchor toggle on the Chain Sampler drives the
in-loop version too, so there is one control wherever you are.

A SAMPLER object is only the step function, so picking KSampler used to leave
the pass with no schedule at all unless a sigma list was typed by hand.
steps + schedule now build one from the loaded model's model_sampling, exactly
as ComfyUI's BasicScheduler does. The schedule dropdown is the switch between
the two sources rather than a silent precedence rule: "use_user_sigmas" — the
default, so nothing changes for an existing config — runs the Sigmas field as
typed, and any real scheduler computes instead, leaving the typed schedule
parked in the field to switch back to without retyping it. Studio logs the fact
that the field is being ignored, and steps is only shown while it applies.
Both frontends, same change.
