Punch list §25 item 4.3.6b complete. capsules/fabric.4th blocks 4921-4924: DISPATCH-GLYPH routing via WITHIN to six bucket words (DISPATCH-DIGIT/-UPPER/-LOWER/ -ASCII-PUNCT/-LATIN1/-GENPUNCT), TOFU fallback, DRAW-GLYPH. Buckets carry one placeholder stroke word each (G-TEST-*), not the real 113-glyph set -- that's item 4.3.6c's scope, deliberately deferred. Also: merged two lines in block 4920 (DECODE-UTF8) to fit mkcapsule's real 64-char x 16-line block limit once a trailing blank separator line is counted against it -- mechanical reformat, re-verified via a DECODE-UTF8 regression check (65/176/8212, unchanged). Verified live on amd64: one representative codepoint per bucket plus one out-of-range codepoint, all seven DRAW-GLYPH results matched expected exactly (400/600/450/250/550/700/500-TOFU). Three-arch acceptance boot clean, Stadium conservation unaffected. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
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 |
