Artemis's 30-rep surface stress campaign was failing 100% of trials on all three architectures: stadium_grant_quota() ran after IDENTITY exec in capsule_birth.c, but Artemis's init.4th auto-runs the stress campaign as part of that same IDENTITY exec, so every STADIUM-ADMIT call during it hit a nonexistent quota slot and refused unconditionally. Moved the grant call before IDENTITY exec. Verified 30/30 reps PASS on amd64, aarch64, and riscv64 post-fix (was 30/30 FAIL on all three pre-fix). Also fixed an independent, real bug found during the same acceptance pass: aarch64's arch_cold_reset() issued PSCI SYSTEM_RESET using the SMC64 calling convention (0xC4000009), which is not a valid PSCI function ID -- SYSTEM_RESET has no SMC64 variant. Corrected to the SMC32 encoding (0x84000009). This did not resolve the separate aarch64 BYE cold-restart exception also found in this pass (root cause not yet found, tested and refuted an interrupt-race hypothesis, documented in FABRIC-2.md Section I for follow-up) but is a genuine spec fix worth keeping regardless. Full writeup, evidence, and the still-open aarch64 crash investigation in FABRIC-2.md Sections H and I. 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.
