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.
Pipeline wiring: core/graph.py gains wire()/unwire(), and the "Models and
pipeline" editor can now actually connect one node's output to another's
input -- sockets and widgets alike, which is what makes "linked inputs"
(several widgets sharing one Primitive node's value) buildable at all,
without a second mechanism. Three adversarial review rounds found and fixed
real bugs along the way: check()'s request builder silently dropped the
wire-specific fields; the widgets loop had no wiring UI at all despite the
backend supporting it, and a widget already holding a link rendered as an
editable box with the wrong (default) value; wiring an input that already
had an unsaved drafted value let the stale value silently win on Save. Also
fixed, found live rather than by review: the Add-node picker stacked two
disagreeing search boxes (an outer server search and filterList's own
redundant client-side one).
Updates window: "Restart ComfyUI" is now a plain, always-available button,
not just something offered when an update already landed. Rolling back or
switching branch on a dirty tree now auto-stashes instead of refusing --
updating still refuses, unchanged, since pulling new commits onto changes
in progress is not something to do without asking. Three review rounds
here too: stashing before reading the rollback target shifted what HEAD@{1}
meant (a real reflog hazard, not just reasoned about); a stash's disclosure
was lost if the step right after it failed; that fix was too narrow and
missed pull()'s own failures inside checkout(pull_after=True) -- the actual
default path -- and rollback()'s own reset failing; and finally, the
broadened fix still only caught GitUpdateError, missing subprocess-level
failures like a hung fetch timing out, which is the realistic failure mode
on a rented GPU box's network.

Most FunPack pipelines run at CFG 1, where a negative prompt does
nothing -- it was one more box beside the prompt every Generate reads,
for a field only worth touching occasionally. The reference pipeline's
negative role now targets "project.negative" instead of
"generation.prompt"; the inspector's Project tab hosts it, in a STABLE
node outside the part draw() tears down and rebuilds on every scene
selection, so a field mounted there survives normal use.
Steps, Sampler and Scheduler are on the main window -- the three v4 buried
several clicks deep in Engine Settings. No new UI: the sampler slot declares
roles the way the prompt and the size already do.
What made that nearly free is that the controls now come from the NODE's own
description, through the settingFor/rendererFor pair the pipeline window has
always used. So a combo is a dropdown of the real choices and a number obeys
the real bounds, and prompt.js lost both of its hand-rolled branches: it no
longer decides what a control looks like, it asks.
File: New project, and every project listed with the open one ticked. The
store has been able to do this since the day it arrived and there was no way
in -- 20 lines of menu.
Three faults found on the way, all in the shared input helper:
* ENTER COULD NOT BE TYPED IN A TEXTAREA. `wire()` bound Enter to commit for
every text control, textareas included, so a multi-line value was
impossible -- the prompt above all, which is the longest multi-line thing
in the app. It has been that way in the pipeline window since it was
written; nobody had typed a second line into one.
* A control committed on blur alone, so autofill, a password manager and any
script setting a value went unheard. It listens to `change` as well now,
and commit() only acts on a real difference so the pair costs nothing.
* A control commits on blur, which means text still being typed is not in
the project yet -- and a tab closing is exactly when that is lost. boot
blurs before it saves.
Width, height and length belong to the PROJECT, not to a scene: a scene
cropped on the timeline and regenerated comes back at the project's size,
because the crop was a timeline decision and a regenerate is a new scene.
They sit in the Constructor beside the prompt -- the two things settled in
one sitting -- and travel to the graph on the path the prompt already uses.
No new mechanism: the pipeline declares roles at `project.video` the same
way it declares the prompt, so core still names no node and no setting. A
role whose value is a number gets a number control instead of a box; that
is the whole of the UI change. What the pipeline does not offer is not
shown, so a graph with no length input simply has no Length.
Bounds are the NODE's and stay there -- it already refuses a value outside
them with a reason, beside Generate. A project file is the one thing here
that outlives the code that wrote it, so everything read back out of one is
checked: a whole positive number, or gone.
Also, four faults the browser suite was already red with before this:
* Six tests still clicked a rail toggle that moved into the timeline head.
* At 420px the panel OVERLAYS the centre -- and the named toggles are in
the centre, so the panel covered the control that closes it. That is the
v4 trap this project forbids. They are not offered at that width now; the
View menu, which nothing can cover, is the way in and out.
* A 768px window laid out 860px wide and scrolled sideways. Root cause, and
it was never about one component: a flex item's automatic minimum is its
CONTENT, so every stack, split, panel body and frame region in the app
handed its content's width upward. A scroller that cannot shrink below
what it holds is not a scroller -- the strip of scenes made the WINDOW as
wide as the strip. Floored at the five places every layout routes through.
* A bin test counted `.cx-cell-glyph` across the whole page, so the timeline
drawing cells with the same glyph in them broke a test about the bin.
The prompt was a slot input on a CLIPTextEncode, reachable only by opening
the pipeline window and finding the node. A slot can now say that one of
its inputs belongs on the app's surface -- a place and a label -- and the
shell offers a region with that name or does not, exactly as a module's
panel works. Core validates that a role is names and nothing else.
Values for those inputs travel addressed by slot rather than as a whole
pipeline, so the window that owns the structure and a box that owns one
value cannot disagree about the slots between them. An address that is
not there is refused: a prompt typed into a box for a removed slot has
gone nowhere, and a run that starts anyway is not the run that was asked
for.
Region stand-ins are empty states now, taken down once something mounts --
'modules appear here' left above the modules that appeared explained
nothing to nobody.
Every module panel was decoration. The values lived in the browser and
nothing sent them, so a modifier switched on was one the run never heard
about. They now travel with the pipeline on every check, and core places
them wherever a module says they belong -- announced, not known, so the
node that carries them is not privileged.
Settings with nowhere to go are said beside Generate rather than
swallowed, and the warning survives the run it is about: the status line
is redrawn by every message, so a warning put there was gone the moment
the run said Queued.
Also: a settings row in a docked panel squeezed its label to one word per
line, because the control keeps a 140px floor and took it out of the
label. Below the width where they fit side by side, they stack.
ComfyUI refuses the WHOLE graph over one wrong value. v4 hit that with a LoRA
file that had been deleted: a feature that was switched off still stopped every
generation, and the message was "Prompt outputs failed validation" over a dozen
loaders. build() checked wiring and required-ness and never looked at a literal,
so check() called such a pipeline queueable.
A combo value that is not among the node choices, and a number outside the
bounds it declares, are now refused here -- naming the slot and the input.
No bounds means unknown, and unknown is not a refusal.
And when the queue does refuse one, its per-node reasons were captured by
run.js and never read: the status bar showed only the top-level string, because
describe() read `node` and the refusal path sets `nodes`.

ComfyUI spells a combo three ways -- a list where the type goes, the string
"COMBO" with the choices under options, and COMFY_DYNAMICCOMBO_V3. Only the
first was read, so every V3 node came back with no choices at all and the
window said "no files of this kind were found" over dropdowns holding seven
entries. A stock install here has 140 of the spelling that was missed.
A union type ("IMAGE,MASK") was compared as a whole string, so a MASK feeding
it was refused -- a legal wire refused, which is as bad as an illegal one
accepted. A MultiType wrapped around a number ("FLOAT,INT" with widgetType)
was read as a socket demanding a source for a field you type into.
graph.py and widgets.py had their own idea of what a type string means; both
now read comfy_types.

shape_problems() reads the slots array. Everything else in the body -- the body
being an object at all, which slot an edit targets, which node it replaces it
with -- was read straight off whatever JSON arrived. `[]` reached `.get` as an
AttributeError; `{"slot": ["a"]}` reached an `in` against a dict as an
unhashable key. Both answered 500 in plain text, which is the refusal nobody
can read that this route exists to avoid.
Round six, two findings, both confirmed.
A malformed slots payload crashed the route with a TypeError and answered
500 in plain text. The round-two fix handled the ABSENCE of slots and not
their SHAPE, so reading slot["id"] off a string went straight through -- and
a refusal the app cannot parse is the failure this endpoint exists to avoid.
The shape check is its own function now, because a malformed REQUEST and an
unfinished PIPELINE are different things and get reported separately.
And a window could still be made unreachable, by resizing rather than
moving. Round two clamped position and said "a window can never be put
somewhere it cannot be recovered from"; size was never bounded, so a corner
drag grew it to 4937px in a 900px viewport and carried its own close and
maximise buttons off the screen, leaving Escape as the only way out.
Capping size to the viewport was not enough either: with x above zero the
right edge still left. Resizing is now capped to the room available from
where the window sits, which is a deliberately different rule from dragging
-- a window may be DRAGGED partly off, because a grabbable strip is
guaranteed and that is ordinary behaviour, but it may not be GROWN past the
edge it is anchored to.
Two rounds of fixes, two rounds of holes in those fixes. Both found only by
attacking the code as it stood after the previous fix rather than stopping
at the report that prompted it.

A floating window remembers its position per id, and only the DRAG handler
clamped. So a window moved to the right of a wide screen and reopened on a
narrow one opened entirely off the viewport: no titlebar on screen to grab,
nothing to drag back, and the position remembered -- unrecoverable without
clearing localStorage by hand. Reproduced at x=1400 in an 800px viewport.
The clamp lives in apply() now, so every path goes through it: opening,
restoring a remembered box, coming back from maximised, and the viewport
shrinking under an open window. Also guarded for a viewport narrower than
the grabbable strip, where the old bound went negative and pushed the window
further off rather than back on.
jsdom cannot see any of this -- getBoundingClientRect is zeros there, so a
window off the right edge measures identically to one in the middle. The
three tests are Playwright, and removing the clamp fails two of them.
And POST /api/pipeline could not accept an empty pipeline: `slots or
default()` resurrects the built-ins, because an empty list is falsy. A client
that removed every slot got them handed back. Absent means "use the default";
empty means "there is nothing", and only one of those is a fallback.
One of the tests I first wrote for this asserted len(x) < len(y) + 1, which
is true of almost anything. It counts the pipeline at every step now and
fails if it ever grows.

Full control did half of what it said and never said which half. It disabled
the mid-run crash guard and left every value refusal in place, so the stated
purpose -- a one-step schedule, a width the model cannot use, let them and
warn -- did not work. Worse, a rejected value was quietly replaced by the
default, so asking for 999 gave 0.4 with a warning about 999.
Now one switch turns off both: the value is passed through, every problem is
said as a warning naming that the consequences are the user's, and a run made
without the guards is identifiable as one afterwards. A key NO module
declares is still never kept, whatever the setting -- nothing reads it, so
keeping it cannot honour the request, only disguise the typo.
core/graph.py was thoroughly tested and called from nowhere: the claim that
a built-in node can be replaced or removed was a property of a library
nothing invoked. It has routes now, and tests that drive them over a real
socket -- the modifiers node removed and the sampler rewired, the VAE loader
swapped for core's, and both refusals coming back as reasons.
Those routes separate two things the old shape conflated. "refused" means
the edit did not happen. "incomplete" means it did and the pipeline still is
not ready -- an unset file picker on a fresh install is the normal case, not
a failed edit, and showing them together would say the wrong thing about both.
And build() could not see a missing REQUIRED input at all, because the
schema lookup flattened required and optional into one dict. A slot with no
model file built clean and failed only once queued.
