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.

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.
