Punch list §25 item 4.3.6g complete. Fixed the cross-arch bug found while first attempting this checkpoint: aarch64 and riscv64 both boot an 800x600 ramfb device (confirmed empirically for both, not assumed), against amd64's 1280x800 GOP framebuffer -- the original verification grid's Y coordinates ran off the top of the smaller screens. Rebuilt the grid to fit 800x600, safe on amd64's larger screen too. All 113 glyphs confirmed legible and correctly positioned on all three architectures, one screendump each, from the identical FORTH command sequence. No code changes -- font.4th/fabric.4th are unchanged since 4.3.6f; this is verification only. Three-arch acceptance boot clean, Stadium conservation unchanged. Stroke font (4.3.6-4.3.6g) is now complete. Per this item's own posture, stopping here before scoping REPL wiring (M8) -- 4.3.7 (TrueType, adjunct) is the scoped-but-not-started next work.

capsules/
FORTH personality files loaded by the VM at boot. A capsule is an immutable, content-addressed payload; its XXHash64 hash is its identity. Any mutation changes the hash and the birth protocol rejects the image.
