FABRIC.md: renumber Artemis-last boundary 4.4 -> 4.5, add new 4.4 REPL item (console visual design scoped this session -- CANVAS is one shared region above the REPL strip, 640x480 scroll box centered within it, stroke font, ANSI color, VM-identity + ACL-identity prompt segments, ~1000-line scrollback), linked to repl-mockup.png. ROADMAP.md: mark M8 section OBSOLETE -- replaced by FABRIC.md 4.4, kept for history only. ttf_words.c: TTF-TEXT's y argument now Cartesian (origin bottom-left of the physical framebuffer, y increasing upward) instead of raw framebuffer coordinates, translated once via fb_height() - y. Verified via amd64 screendump (logs/20260811-070418/), text renders right-side-up with increasing y moving up the screen. 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 |
|---|---|
| 2048–2099 | init.4th |
| 2100–2199 | doe.4th |
| 3000–3999 | workload capsules |

Each block is limited to 1024 bytes. Verify with wc -c before committing.
