Two pieces of the "port v4's exact UI onto v5's backend" plan:
- core/contract.py: new optional ModuleSpec.category field (closed set:
continuity, guidance, conditioning, sampling, post, system), validated in
core/schema.py, threaded through core/registry.py's FIELDS and
to_manifest(). Presentation grouping, independent of STAGE (execution
order) -- a module can be stage="sampling" and category="guidance" at
once. Only the 4 existing modules that actually render a settings panel
(alg, sharpen, appearance, full_control) got a category assigned; the
other 12 have none to categorize (no SETTINGS block) and stay
uncategorised, which is valid.
- v4's frontend (movie_editor/frontend/*, ~29k lines, 61 files) copied
verbatim into app/legacy/. core/routes.py's "/" route now serves
legacy/index.html instead of the composer entry point; a <base> tag in
that file resolves its own relative script/link tags against
/funpack/app/legacy/ regardless of what URL it's served at, so every
file moved as a unit with zero per-file path edits. Verified live: all
61 assets load 200 OK, the real v4 onboarding screen renders pixel-for-
pixel (it's the actual DOM/CSS, not a reimplementation), and several v4
API calls (/api/media, /api/projects, /api/git/status) already succeed
against v5's real backend by coincidence of shared route naming -- the
rest 404/405 as expected, since api.js's ~90 functions haven't been
rewired to v5's actual routes yet (next piece of this plan).
The old composer entry point (app/index.html, app/composer/**) stays in
the tree, unreferenced, until a later cleanup pass once nothing imports it.

v4's Chain Sampler became a hub: 8183 lines, roughly seventy optional
inputs, a _sample_chunk that grew six ALG arguments, and a hardcoded list of
knobs silently inert on one model family. Every technique that needed the
loop was added to it, so it collected all of them.
This one picks an algorithm and a schedule from ComfyUI's own registries --
so a sampler it gains appears here without an edit -- and runs them. Three
things stop it becoming a hub again. It never learns what a model-side
modifier is. Sampler-side ones reach it through ONE call site,
chain.process(ctx, latent), which cannot grow because the step travels in a
context object rather than in the signature. And it declares the hook points
it offers, so core hands it only what fits and it never names a modifier.
Some modifiers genuinely cannot ride on a model: they need the step index,
the schedule, or a second pass. Those attach here instead, and one asking
for a hook this sampler does not offer is absent and said so, not
half-running.
Verified against ComfyUI's own guider path with real weights: bit-identical
output. That took correcting the method, not the code -- see below.
MEASUREMENT, corrected: sampling on this Mac's MPS backend is
NONDETERMINISTIC. The same node with the same seed and the same inputs
differs run to run: 2.42 by max latent difference, 0.0008 by mean pixel gap.
Comparing by MAX said this sampler diverged from core by 14.2 and it was
about to be "fixed"; by MEAN against a measured noise floor it is 0.00000
while core against itself is 0.00183. Every comparison here now runs a
control twice first. Re-checked the Detail modifier the same way: 145x the
floor, so that claim stands.
Also matched what core's sampler actually does and this did not:
fix_empty_latent_channels using the ratios our own empty-latent node reports,
the preview and progress callback, the move back to the intermediate device,
and dropping the ratio keys so nothing rescales twice.

Colour is a preference, so it is a setting: hex in, hex out, one spelling,
refused if it is not one. A module handed "red" in one place and "#f00" in
another guesses wrong somewhere.
Image and mask are NOT settings and deliberately have no type. They are
data -- tensors the app uploads and the graph wires -- and ComfyUI already
has socket types for both. Putting a drawn mask in a JSON settings payload
would be inventing a second way to move something that already moves.
Runs now have an id. Previews, progress, results and log lines all have to
be attributable to one generation, and ComfyUI gives a node no way to ask
which run it is in. So FunPack marks its own, every log record carries it,
and the history can be filtered to a single run. Readable rather than a
uuid, because it is going to be read: "run 7" is findable in a wall of
output and a hex string is not.
The colour element was caught by the registry-driven rule test before it was
finished -- an element with no catalogue demo is neither shown nor attacked,
so coverage keeps up with the registry instead of lagging behind it.

Derived from latent_format where that is possible, which is every
single-tensor model: SDXL, Wan21 and LTXV all come out matching the numbers
core's own nodes compute, including models that ship after this.
H3 cannot be derived and is the reason modules exist. Its latent is a
NestedTensor of a video and an audio branch, its video channel count is not
the latent_channels its format reports, and its length snaps to a frame
grid. So modules/models/minimax_h3 claims it and builds it, importing the
grid from ComfyUI rather than copying a second definition of it.
Nothing outside that folder names a model, and nothing here assumes video:
a 2-D latent format yields an image latent with no branch anywhere.
Modules reach core through modules/_core.py. ComfyUI imports a pack by file
location, so an absolute `import core` in a module resolves under pytest and
not under ComfyUI -- the node then never registers, silently. That cost the
same bug twice, so there is now a test that loads the pack the way ComfyUI
does, in an isolated subprocess whose cwd is NOT the repo. The first version
of that test passed with the bug reintroduced, because cwd was on sys.path.

ComfyUI's V3 entrypoint replaces NODE_CLASS_MAPPINGS, which must not exist
at all: nodes.py checks it first and reaches comfy_entrypoint only in an
elif, so an empty dict registers nothing and reports no error.
A module declares NODES for graph structure and SETTINGS for preferences,
and the two never mix -- a saved workflow stores class_type and input
names, so letting a new setting add a socket would rot existing graphs.
Traits now come from two places: facts core can read off any model, and
providers announced by a model's own module. Core names no model, so
supporting a new one is a folder rather than an edit here.

One declaration does three jobs: renders the panel, carries the defaults, names
the values that come back. A module writes no DOM and reads no DOM.
Validation refuses rather than repairs -- unknown type, a renderer its type does
not have, a label that is not text, a default outside its own bounds, a when
naming a key the module never declared. A module that is wrong does not get a
best-effort panel; it does not load, and says why once.
Ordering is by declared relation and stage, never priority numbers, and a cycle
drops only the modules in it. Compatibility is by trait, never model name.
The shell hands a module { composer, values, on, shell } and nothing else: no
node, no document, no kit internals. It cannot style anything because it is
never given anything that could.
catalogue/hide.html puts one good module and five broken ones through the real
shell and shows the result: one panel, five absent, no placeholders. The lint
fixtures make the scanner prove it catches each rule, so a clean scan means
something.
First slice: modules/system/appearance. Two settings, an optional ui.js, and
clicking Light actually turns the app light.
