Punch list §25 item 2.1 complete. vm_physics_touch() no longer takes a wall-clock timestamp -- it reads fleet_heartbeat_tick_count internally, which is execution-paced (vm_runtime.c:143), not wall-clock. VMPhysics.last_active_ns -> last_active_tick, VMFleetTouchSample.elapsed_us -> elapsed_ticks, and a new explicit `touched` flag replaces the old `> 0` sentinel (tick 0 is a legitimate value a first touch can land on, unlike wall-clock ns). Verified: three-architecture boot (amd64 x2, aarch64, riscv64), all reaching ok> with identical dict_hash=0x3d4e1daf289da94f matching the item-0.10 baseline. No new compiler warnings in the touched files. Honestly flagged, not fixed: with Tripod pruned to Hera alone (item 0.1), vm_physics_touch()'s fan-out has no other live VM to pull heat from, so the fleet-heat-sum acceptance criterion is trivially satisfied rather than genuinely stress-tested -- a real check needs Phase 4's multi-VM fleet. fleet_transfer_slope_q48's seed (65536/3) was calibrated for elapsed microseconds and has not been re-fit for elapsed ticks; left as-is rather than guessed, deferred to item 5.1's DoE work.

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.
