H3's latent upscaler loads through the H3 module (ComfyUI's loader has no
branch for it); an upscale resizes H3's anchor pin so pass 2 stays pinned.
FunPack Sampler takes an optional wired schedule, run exactly as written.
New preset: H3 Reference to Video + second pass.

keep_proportion/extra_padding/invert_crop (ImageTransformKJ) and format
(SaveVideo) were wrapped in a redundant {"field": "value"} dict instead of
the plain string ComfyUI's own DynamicCombo expansion expects at the wire
level -- every one of them silently failed graph validation and fell back
to the node's own default, undermining the "total_pixels" resolution-fit
behavior this preset exists for. Found by loading the preset in a real
browser against real node schemas; the dev server never had comfy_extras
or KJNodes registered before now, so this was invisible locally until
tools/devserver.py also gained real node registration (init_extra_nodes +
KJNodes' load_custom_node, matching what the pytest `registered` fixture
already did).
The two pipeline_preset tests that were supposed to catch this had too
broad a filter -- it excluded ANY "is not one of" message as an assumed
"combo not chosen yet" state, which in this codebase actually shows up as
"needs X and nothing fills it" instead. Tightened to exempt only the three
loader-file combos genuinely left unset on a fresh install.
Verified live: preset loads with zero combo-validation problems, only the
three expected unset-loader-file messages remain, and Generate correctly
refuses with an honest reason rather than a false success.
Pieces B and C: Scene gains source_image (aspect-ratio reference only --
resolution itself stays a project.video setting, ImageTransformKJ's
"total_pixels" keep_proportion fits the picture's aspect into that budget)
and references (media ids, in order). Inspector's Scene tab gets pick/clear/
remove controls; picking routes through the existing Media bin via a small
pending-pick handshake in boot.js (one bin, one onPick, so "which field
asked" has to be tracked between the click that asked and the click that
answered).
References wire into MiniMaxH3ReferenceToVideo's ref_images autogrow input
dynamically, per run, only for what a scene actually has -- an unwired slot,
not an empty image, is what "not in use" means to that node. The target is
data on the role itself (wireTo), not a slot id boot.js would otherwise have
to know, keeping the "core never names an implementation" contract intact
one layer up into the app.
Verifying this exposed a second real core gap (after the MatchType one):
core/graph.py had no idea what an Autogrow (V3's io.Autogrow) input even
is -- "ref_images" reported as one opaque COMFY_AUTOGROW_V3 slot, its real
per-instance sockets (ref_image_0, ref_image_1, ...) invisible to
declared()/build(), so a wire naming one was refused as an input the node
does not have. Fixed generically in comfy_types.py (autogrow_instances())
and graph.py, confirmed against ComfyUI's own _io.py (finalize_prefix's
dotted join, build_nested_inputs's runtime un-nesting) -- not guessed, and
proven end to end with a real override()+build() test using the exact edit
boot.js makes.
Piece A of the H3 workflow port: the loader/SigmaShift/ImageTransformKJ/
R2V/sampler-at-CFG-1/decode/video-mux chain the H3 user runs by hand today,
offered as a preset (GET /api/pipeline/presets) loadable into the same
editable pipeline core/graph.py already supports -- not a second "default",
which module-load order would make ambiguous.
References are deliberately NOT pre-wired into R2V's ref_images autogrow;
an unwired optional slot is what "not in use" means to that node (absent
from its ref_images dict), not an empty image degrading its <Picture i>
numbering. boot.js wires them per-run based on what's actually picked --
next commit.
Building this against a real ComfyUI+KJNodes registration (not a fake
schema) surfaced a genuine core bug: core/graph.py's from_comfyui() had no
idea what to do with a V3 MatchType socket (ImageTransformKJ's own image
input) -- its bare type name "COMFY_MATCHTYPE_V3" matched nothing, so a
completely legal IMAGE wire into it was refused. Fixed generically in
comfy_types.py (match_type_union()) and graph.py, for any node using
MatchType, not special-cased to this one.
Every node's own OUTPUTS were invisible on its own panel in the pipeline
editor -- wiring an input already let you pick a source, but opening the
node that PRODUCES something told you nothing about what it makes or
whether anything reads it. Found live, by a real user just looking at a
node, after two full review rounds that only ever checked the consuming
side. Fixed with a read-only "Outputs" section per node, naming each
output, its type, and who (if anyone) currently wires from it.
Also: model family detection. core/probe.py reads a safetensors header
(tensor names only, no weights) and asks every installed model module,
through the same capability-lookup mechanism already used for
empty_latent/decode, whether the file is its own -- core never names a
family itself. A real, adversarially-found bug in the ported signature:
one of MiniMax H3's three candidate prefixes doesn't correspond to any
prefix ComfyUI's own loader actually resolves to, traced through
comfy/model_detection.py and comfy/sd.py -- the probe could have called a
file H3 that ComfyUI's real loader would refuse. Removed, and pinned with
a dedicated test module. A second finding narrowed the folder search to
only the folders FunPack's own loaders actually read from.
