Picked up from a crashed session: xhci_driver.h/xhci.h already had the bulk_in/out_ep_addr/max_packet fields and Endpoint-descriptor offset macros scaffolded, but the actual walk that populates them was never written. Added it: after 2f confirms a Mass Storage/SCSI/BOT interface, a nested walk continues through the Endpoint descriptors that follow it (bDescriptorType==5, stopping at the next Interface descriptor or end of stream), keeping only Bulk-type endpoints and splitting IN/OUT by bEndpointAddress bit 7. Also reset the four new fields in xhci_bringup(), which the scaffolding had missed. Also completed 2e's disconnect teardown, which was fully implemented this session (not scaffolded): a Disable Slot command is now submitted on a real disconnect, with the port's tracked slot ID captured and cleared from port_slot_id[] immediately (before the command completes) so a fresh connect on the same port isn't confused for one already in progress, and DCBAA[slot_id] cleared only on a successful completion. Verified live via QMP hotplug (deliberate device_add/device_del against freshly launched, individually-tracked instances -- not whatever happened to be attached at boot), all three architectures, byte-identical: bulk IN endpoint=0x81, bulk OUT endpoint=0x02, then a clean disconnect -> disable slot succeeded, no wedge. Caught and fixed a documentation near-miss in the same pass: an initial draft cited the probe-free three-arch acceptance boots as this feature's verification evidence, but a stale leftover log directory from a pre-crash orphaned QEMU process had been picked up by an `ls -dt | head -1` glob during monitoring and mistaken for this session's own result -- the real acceptance logs never had a device attached at all. Re-verified against real PIDs and real log paths before writing FABRIC-2.md's final writeup. FABRIC-2.md Section X Milestone 2 updated: 2e's disconnect-teardown checklist item marked done, 2g's endpoint-identification item marked partially done (identification only -- Configure Endpoint / EP Context wiring is still open).

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.
