First entry in the "cookbook" track: a demo capsule plus HOWTO, per the
sequencing laid out after the POST-coverage sweep. Built entirely in FORTH
on top of existing primitives -- fabric.4th's LINE (raster Bresenham) and
Q.SIN/Q.COS (Q48.16 trig), plus PLOT/FB-WIDTH/FB-HEIGHT -- no new C words.
FORWARD/BACK/LEFT/RIGHT/PENUP/PENDOWN/HOME/SETXY/SETHEADING/SETCOLOR give
the classic turtle model; POLYGON and STAR compose FORWARD+turn into simple
demo shapes; TURTLE-DEMO is a one-call visual smoke test. Not wired into
init.4th -- REPL-invoked only, matching the original idea's own scope.
Verified: mkcapsule --lint clean, hosted-build logic trace shows zero VM
errors and correct stack balance through the whole vocabulary, zero build
warnings and capsule loads cleanly on all three kernel architectures.
Visual pixel-level confirmation not yet done (needs an interactive
gtk-display session or driving past the ~25-30 min DoE-before-REPL wall),
documented as an open item in the HOWTO.

The 30-replicate Artemis surface-stress campaign ran across all three
architectures: 30 reps x 50 trials x 3 arches = 4500 trials, zero failures.
The block_words.c stale-pointer cache-aliasing fix holds at scale.
Adds ART-STRESS-CAMPAIGN (block 4174) plus ART-STRESS-REP rep-tagging in
the CSV header/summary emitters, so a multi-replicate run is distinguishable
in the serial log. Campaign auto-invoke is left enabled in block 4170 for
now; Makefile.starkernel's QEMU boot deadlines stay at 12h to accommodate
long-running experiments.
Adds docs/working/architecture/ARTEMIS-COMPUDYNAMICS-IMPLEMENTATION-PLAN-20260802.md,
which documents the real gap this campaign exposed: block heat and message
heat do not decay at all. ART-TICK has zero call sites anywhere in the tree,
and HERMES-TICK has zero C call sites -- every caller is Hera poking it by
hand. BLK-HEAT@/MSG-HEAT@ read a number nothing ages, so blocks never reap
by cooling and message TTL never expires on its own.
The plan mirrors word-level physics as the reference model: lazy decay at
each access point against vm->heartbeat.tick_count, plus a bounded
background sweep with a resumable cursor (the existing answer to "sweeping
22,998 blocks per tick is too expensive"). Phase 1 Artemis, Phase 2 Hermes,
Phase 3 K participation deferred behind the Logical BAM.
The plan's preamble also records a wrong turn taken while investigating:
chasing VM-fleet heat instead of block heat, and building synthetic
Hera-driven VM-EXEC calls to force a physics reading -- which TRIPOD.md
prohibits outright. That work was reverted; the record is kept so it isn't
repeated.
Status: plan approved in shape, NOT final and NOT started. Six open
questions need answers and further design discussion is pending.
