Chains off a confirmed Mass Storage/SCSI/BOT interface match via the existing next_action deferral mechanism: device descriptor -> config descriptor -> SET_CONFIGURATION is now a single automatic sequence. bConfigurationValue is read directly out of the already-fetched config_descriptor buffer, no extra transfer needed. First write control transfer this driver has issued (every prior one was a read), so it needed its own submission helper, xhci_ep0_control_write_nodata() -- SET_CONFIGURATION has no Data Stage (wLength=0), and per USB 2.0 spec 8.5.3 a no-data control transfer's Status Stage is always IN, the reverse of an OUT-data request's status stage. XHCI_SETUP_TRT_NO_DATA already existed in xhci.h, unused until now. Verified live via QMP hotplug, all three architectures, worked first try, byte-identical: "set configuration submitted" -> "device configured", guest stays running throughout (checked via QMP query-status). Disconnect confirmed clean on every arch afterward, no wedge. FABRIC-2.md Section X Milestone 2f updated -- 2f is now fully complete, 2g (Bulk-Only Transport) can start.

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.
| Range | Owner |
|---|---|
| 2048–2099 | init.4th |
| 2100–2199 | doe.4th |
| 3000–3999 | workload capsules |
