FABRIC.md -> FABRIC-0.md FABRIC-2.md -> FABRIC-1.md FABRIC-3.md -> FABRIC-2.md (the current/living document) FABRIC-4.md unchanged (new #3 to follow separately) Every cross-reference repo-wide updated to match, including doc-comment citations inside kernel source (.c/.h) files -- done via an ordered placeholder substitution (FABRIC-3.md->placeholder2, FABRIC-2.md-> placeholder1, FABRIC.md->placeholder0, then placeholders resolved to final names) in a single pass per file to avoid double-shifting already-renamed references. One line in capsules/font.4th grew past the 64-char block-format limit as a side effect of the longer filename; shortened it and reverified with mkcapsule --lint (34/34 pass) before rebuilding. Verified 3-arch boot to ok> (amd64/aarch64/riscv64, each in the foreground) after the fix; logs and DoE CSVs from this session's verification runs included per this repo's own audit-artifact convention.
