Validated on the rental and it does not earn its place: 3.5 minutes against 1
for the same clip, worse picture, garbage audio. Some of that was mine — no
weight prefetch across the 50 blocks, a host-offloaded K/V cache, and an extra
commit forward per chunk — but fixing those only buys parity on speed, and the
technique's real win is unbounded length, which H3 already covers natively at
the lengths in use here.
Gone: h3_causal.py, the four h3_causal_* sampler widgets and their Engine
Settings rows, `chunk_causal` on the diffusion loader, and five test files.
KEPT, because it is not about this at all: the LoRA key RENAME table. Stripping
a wrapper head leaves `blocks.0...`, comfy's key map has no bare form, and the
file silently applies nothing — 532 keys, zero applied, no error. That was
breaking any PEFT-style adapter named this way, not just the one that found it.
Its tests moved to test_lora_shape_mismatch.py alongside the MATCHED NOTHING
diagnostics.
Two INPUT_TYPES widgets go with this (h3_causal_* on the sampler, chunk_causal
on the loader). A saved workflow carrying them loads fine — both were optional
and are matched by name — but the values are ignored from here.
Tests: 1700 python, 68 JS.
