Stadium console fabric words (FABRIC.md items 4.3.3/4.3.5/4.3.7e/4.4q/ 4.4v/4.4y). All four files gate their real hardware-touching bodies behind __STARKERNEL__ (and, for keyboard, architecture too): - StarForth_Framebuffer_Words.thy: PLOT/FB-WIDTH/FB-HEIGHT fully modelled for the hosted-build fallback (deterministic, no hardware dependency); kernel bodies (fb_put_pixel/fb_width/fb_height) deferred. Finding: FB-WIDTH/FB-HEIGHT have no overflow guard before pushing -- second instance of this class of bug after DECAY-RATE@. - StarForth_Keyboard_Words.thy: all 6 words' non-kernel-or-wrong-arch fallback modelled (fixed constant pushes / no-op); third and fourth missing-overflow-guard instances. Real hardware polling (i8042/virtio-input) deferred. - StarForth_Scroll_Words.thy / StarForth_TTF_Words.thy: both files gate registration itself behind __STARKERNEL__, so their words don't exist at all in a hosted build -- no fallback to model, sentinel-only. Suite now 48 theories, confirmed green via a full clean rebuild (HOL- Library cold-built in 15m18s after an accidental heap clear, StarForth itself 33s).
