It goes through `gtk-launch` and the app's desktop entry, so `~/bin` need not be on quickshell's PATH. +When the image staged for the target screen is too small for it (the yellow +or red border), "Upscale 4×" appears beside it. It runs Real-ESRGAN through +stable-diffusion.cpp's `sd-cli -M upscale` and replaces the file in place, +keeping its name, so wallp's state and the engine's lists still find it; +Apply then sets the larger copy. Only files under `~/Pictures/wallpapers` are +offered. + +Which Real-ESRGAN model is decided per image by Imajev-4B, a small Jev-style +vision decision model, run once through `llama-mtmd-cli` on a 512 px +thumbnail with a grammar that allows only "A" (anime) or "B" (photo or +render). Greedy decoding then returns the higher-logit option, which is the +decision; about 1.7 s. Anime goes to the anime model, which keeps line art +clean; anything else, and any failure of the decider, to the general one. +Measured on 22 wallpapers, it got all 12 anime and all 4 photos right and +called 4 of 6 painted 3D renders anime, which then come out smoother than +painted. The 2B got 17 of 22, and a three-way prompt adding "painted or +render" dropped both to 15 or fewer, with most anime called painted. + +The button takes two clicks so the choice shows before anything is +rewritten: "Upscale 4×: pick model" runs the decider and becomes +"Upscale 4× (anime)" or "(photo)", and that click upscales. The decision is +kept for the image it was made for, so staging another and coming back +still shows it. + +The models are read from `/data/LLM-models/SD/upscalers/` and +`/data/LLM-models/SD/imajev/` (`Wallpapers.upscalers`, `Wallpapers.decider`). +Deciding takes about 2 seconds, upscaling a 1280x720 image about 7. sd-cli exits 0 even when the +model fails to load, saving the input unscaled, so an `[E]` line in its log +counts as a failure too, and a failure leaves the original untouched. + `wallp` does the actual work, including running `udt-accent`, so the accent follows the new wallpaper exactly as it does from a terminal.
