Closes §I.3 (Milestone 5 remainder): WIREBIND now tracks which VM is attached via the home-blocks USB path, and a new EJECT word plus the existing hot-unplug signal both flush/reset-console/kill through it (FABRIC-3.md §F.10). Closes §I.8 (EXPIRE/ACL), re-scoped: the original "admit the zuse session as a Stadium patron and reap on TTL" plan was invalidated a second time -- Zuse authenticates directly onto Hera, who is patron zero and permanently pinned, so there is no patron for a reap sweep to ever find. Built instead as a detach-triggered logout (capsule_zuse_boot_logout()), the same trigger EJECT/hot-unplug use for regular WIREBIND users, so neither identity is a special case. Required a companion fix: install_and_activate() used to skip re-running ACL-ZUSE-BOOT whenever the cert was already installed, which made a logout permanent for the rest of the boot; the outer re-attach gate now checks zuse_session (clears on logout) instead of zuse_cert_installed (a deliberate permanent one-way ratchet, left untouched). Verified 3-arch boot to ok> (amd64/aarch64/riscv64, each in the foreground) after both steps; logs and DoE CSVs from this session's verification runs included per this repo's own audit-artifact convention.

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.
