Robert Allan JamesandClaude Sonnet 5 2960989100 font.4th: TEXT entry point, UTF-8 string rendering (item 4.3.6f)
Punch list §25 item 4.3.6f complete. TEXT ( c-addr u x y size color -- )
walks a UTF-8 byte string, decoding one codepoint at a time via
DECODE-UTF8, drawing each via DRAW-GLYPH, and accumulating the cursor
X by the glyph's em-advance scaled to pixels. Uses 2>R/2R> to stash
the DECODE-UTF8 remainder off the data stack while DRAW-GLYPH's args
are pushed.

Defined in font.4th, not fabric.4th, so its compiled DRAW-GLYPH call
binds to the real definition, not fabric.4th's 4.3.6b placeholder --
same early-binding constraint as DISPATCH-GLYPH itself.

Verified live: a string mixing ASCII, Latin-1 (degree sign), and
General Punctuation (em dash) renders correctly in one TEXT call with
proportional spacing, no overlap.

Three-arch acceptance boot clean, Stadium conservation unchanged.

Design of Experiments (DoE) campaign data and analysis for the LithosAnanke kernel.

  • bare_metal/ — the bare-metal DoE experiment: blind full-factorial 2⁴ runs measuring the L8 Jacquard mode selector's effect on the Steady-State Machine across amd64/aarch64/riscv64. See experiments/bare_metal/README.md for the full directory layout (runs/, latest/, analysis/{charts,tables,report}).

Hosted-VM DoE campaigns (factorial/heartbeat/ablation studies) live under docs/working/experiments/ instead — this top-level directory is specifically the kernel/bare-metal side.
