Adds a one-time boot diagnostic in kernel_main.c, right before sk_repl() is entered: bounded wait for 3 real heartbeat ticks, then prints tick count, TIME-TRUST, and variance. Needed because printing immediately after apic_timer_start() (as first tried) measured 1 tick on amd64 and 0 on riscv64 -- not evidence the heartbeat doesn't work, just that almost no wall time elapses between arming the timer and that point in boot; report it honestly rather than let it stand as a false negative. Verified this session (logs/20260804-001727, -001805, -001850, -001948, -002021): - All three architectures boot to ok>. - Tick count non-zero: amd64 4, riscv64 3, aarch64 3. - riscv64: trust=Q48_ONE exactly, variance=0 -- architecturally invariant counter, as designed. - amd64: dict_hash=0x3d4e1daf289da94f, identical to the pre-item-0.8 baseline (logs/20260803-231322) -- unchanged output, satisfying the GAP-A1 control. - Two consecutive amd64 boots produced the identical dict hash -- reproducible, no wall-clock leakage into patron state. Phase 0 (Substrate) is complete. Punch list §25 item 0.10 complete. 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.
