Reap mechanism (increments 2+3): temporary probe using Artemis as a safe stand-in parked identity, 3/3 checks PASS on all 3 architectures (refuse on SWITCHED_OUT, correct post-reap state, switch-signal slot released). Probe reverted, all 3 architectures re-verified clean. Live multiuser verification (increment 4, no code changes): a real previously-unattached identity thumbdrive attached via QMP on a running boot on all 3 architectures. VM-EXEC dispatch into her own live VM computed correctly, tagged with her own name in console output, full Tripod fleet unaffected. EJECT cleanly tore down both her VMs and released the switch-signal slot -- confirms increment 1's per-device fix under a real live attach/detach. Found and flagged, not fixed: interactive USE on a freshly-attached identity halts the kernel outright. Confirmed NOT caused by Stage 4 -- reproduced identically on the commit before any Stage 4 work. Direct VM-EXEC dispatch into the same identity works correctly; this is specific to the USE/BINDSTEP codepath, plausibly never caught before since every prior identity campaign used VM-EXEC, never interactive USE. Stage 4's original scope is complete: multitasking (Tripod) and multiuser (WIREBIND) are now genuinely composed, verified against real hardware-driven identity attach on all 3 architectures.

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.
