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.

ComfyUI-FunPack v5 — "Cunning Cranberry"
FunPack v4.0.0 is going to be the latest release of classic FunPack. Next update is another milestone update, or shall I say, a full rework.
Maintenance of current FunPack became a mess — forgetting to add or remove buttons from/to UI, finding functions that don't do anything but still present in the code absolutely randomly, trying to keep the UI neat while it has no strict boundaries on how it should look like, and of course — making it easy for users to understand how FunPack operates and how you can operate it — this is all time, money and token-consuming.
General idea behind the FunPack v5 rework is writing it from scratch, with a new architecture where a feature can't be forgotten, where a wire can't be missed, where one failing module never stops whole process from executing. Loaders and features would tell the UI by themselves what sorts of inputs they need and where to put it — and UI will compose them according to design guidelines it would have. Samplers would become independent from features — if a feature is available and enabled, sampler would call it. If it's not — it gets skipped and doesn't even appear in the UI so it won't confuse you.
Most of this comes from a FunUI backend draft that got shelved after understanding on how much time has to be invested into polishing it. Without a community support and wide usage it would become another dead project only one person in the world needs but no one else.
Come to think of it, FunPack already became something alike, with an exception — this project is more than alive, and while I can, I will support it.
Final goal is to make FunPack an ultimate answer for a novice's question "I don't know how to generate — what do I install and how do I start?" and for a professional's question "I need a UI with all the cutting edge techniques available on day 0 — which one?"
Preparation for the v5 had started.
FunPack v5.0 "Cunning Cranberry" — coming fall 2026.
This branch is a clean start. Classic FunPack lives on main.
