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.

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.

Block namespace
Block ranges are shared across all loaded capsules — collisions cause silent word-definition overwrites.
| Range | Owner |
|---|---|
| 2048–2099 | init.4th |
| 2100–2199 | doe.4th |
| 3000–3999 | workload capsules |
| 4000+ | user-defined (ACL.4th, zuse.4th, …) |
Each block is limited to 1024 bytes. Verify with wc -c before committing.
