First real generation through FunPack's nodes: SD1.5 on this Mac, real
weights, a real picture of an apple. Everything before this was static.
What it proved, on a real model rather than a fixture: the empty latent
takes its shape from SD1.5's own format with no family branch anywhere
(1, 4, 64, 64, an IMAGE latent from a pack built for video); the traits read
off the live model are predict_eps and spatial_latent; and ALG is correctly
absent, saying "needs temporal_latent", rather than running on a model with
no time axis.
What it found: the absolute-core-import bug again, this time INSIDE A
FUNCTION BODY. It imported fine, registered fine, passed 258 tests, and
raised at execute time -- during the generation. A suite that imports every
module cannot see an import that only happens when a node runs, so the check
for it is now static and walks the AST: no module may name `core` anywhere,
at any nesting, except through the shim.
The dev preview loaded one module in nine. It runs system python, which has
neither ComfyUI nor torch, so every module that imports either was absent
and the app looked almost empty while reporting nothing. It now re-execs
under ComfyUI's interpreter. Looking at the app is meant to be how the app
gets tested; it has to see what ComfyUI sees.
ALG asked for a mount point no region offered, so its panel vanished in
silence. The shell now offers one per stage, and a modules page lists what
loaded, what asked for a mount nothing offers, and what failed to import --
absence is correct behaviour and indistinguishable from "never installed",
so somewhere has to say which.

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.
