It read the prompt length from transformer_options['c_crossattn'], which
ComfyUI never sets, so every block ran the stock forward. A model wrapper now
records it per call. Per-token mod rows (any pinned frame) no longer disable
it, and the step window reads the real schedule.

Native port of the community "H3 Shadow Negative" pack's Basic scope: runs the
negative CONDITIONING (already threaded through the sampler, otherwise dead
weight since H3's CFG is fixed at 1.0) through H3's DiT blocks as a second
shadow stream and pushes the real stream's attention output away from it,
NAG-style. Non-composing with REINS/Q-steer/av_decouple/block-repeat/
attn_temperature by design -- replaces a block's forward outright and prints
which existing patches it superseded.
Full Editor (Cutting Room) UI exposure lands in this same change, along with
explore_first_step's own missing Editor UI from an earlier session.
