xhci_bringup() now scans for already-connected ports at bring-up (xhci_scan_ports_for_already_connected()), not just later hotplug events, so a USB device present on the QEMU command line at launch is detected. Makefile.starkernel attaches disk/zuse.img on the xhci0 bus by default in all three arch qemu targets (ZUSEDISK=, empties for a bare boot). capsule_mint_identity() gained a drive_known_blank param to skip a fully redundant second homeblocks_sig_check() when the caller already confirmed HOMEBLOCKS_SIG_BLANK itself. Root-caused what looked like a hang after the drive attached: Artemis's fence still carried a genesis marker from before a mid-session reformat, while the reformatted disk/zuse.img read back BLANK -- a mismatched pair capsule_zuse_boot_try_attach() correctly declined to act on, leaving the boot idling at a plain ok> with nothing left to log (indistinguishable from a hang under slow TCG). Fixed by zeroing both disk/artemis.img and disk/zuse.img at their original sizes, giving a matched blank pair. Verified full three-architecture acceptance: amd64 fresh genesis-mint, aarch64/riscv64 clean reload against the same now-minted images.

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.
