Decode now takes the MODEL, so a provider answers "is this mine" by identity
instead of by shape. H3 was claiming any latent that happened to have two
parts -- right today because it is the only thing producing one, wrong the
moment a second AV model exists, and wrong in the way that reads as an
unrelated fault rather than an error. It declines when the model is not
wired, and the node says that is what is missing.
That completes the shape a model module should have: one folder saying how
this model behaves at each stage -- what it is, how its latent is built, how
its output is decoded -- instead of that knowledge spreading through the
conditioning and sampling code as special cases.
Added a modifier that runs on SD1.5, because a feature nobody can watch is a
feature nobody can check. It declares no traits, so it applies everywhere,
which is the other half of the rule ALG demonstrates by narrowing. Measured
on this machine at a fixed seed: off and on differ, 0.4 gives a visibly
richer picture that still reads correctly, and 1.2 blows the highlights --
so the range is -1..1, set from what was measured rather than from a round
number. A slider whose top half destroys the image lies about its range.
Two things found while building it. ComfyUI has a real circular import
between nodes_latent and nodes_post_processing that resolves only because
init_extra_nodes reaches one first; a custom node has to break it the same
way. And the accumulation bug returned through a third door: stripping
handled keyed wrappers but not the anonymous function lists on
model_options, so chaining doubled the effect. Tagging is now generic -- it
looks for our mark rather than for a list of hook names that would need
keeping current.

Core already turns images into a video and writes the file, and handles
containers, codecs and muxing properly. Writing our own would be a worse
copy of tested code, so there is no FunPack save node and no reason for VHS
either.
What core cannot generalise is decoding a latent that is not one tensor: an
AV latent has two branches wanting different VAEs, and their arrangement is
the model's business. Same rule as the empty latent -- a model module may
claim it, and H3 now does. A nested latent nobody claims is refused rather
than handed to vae.decode, which would raise somewhere confusing or quietly
decode one branch as the picture. A missing audio VAE is named, because
returning no audio looks exactly like a model that makes none.
With this the pipeline closes end to end using FunPack's eight nodes and
core's samplers and video nodes -- verified by loading both together. That
matters more than the node count: until now nothing FunPack produced could
be measured, only reasoned about.
