Verified live on amd64: booted with the xHCI controller present but no USB device attached (no Port Status Change at ok>), then hotplug-attached a virtual USB thumb drive via QMP (usb-storage on xhci0.0, backed by disk/usb-thumbdrive-test.img) and got an immediate port status change event -- the real connect trigger Milestone 2e's PORTSC handling will consume next. Confirmed blk_subsys_attach_device() (src/block_subsystem.c) is already the correct integration point for USB -- it already appends a new device to the end of the existing LBN chain, matching the intended design. Documented the remaining gaps: no blkio_usb.c backend yet, no hot-detach path in the device chain yet. Decided the on-drive layout for USB thumb drives: GPT-partitioned (unlike artemis.img's whole-device StarForth header), ~1GB metadata partition + remainder for blocks, 16GB reference drive size, sizing tentative. No GPT parser exists in kernel code yet -- new prerequisite work for Milestone 2h/3, not blocking current 2e work. disk/usb-thumbdrive-test.img added as a tracked test fixture, per this repo's standing convention that virtual disk/thumb-drive images used for testing are committed, not left in scratchpad.
