xhci_poll_events()'s Port Status Change branch now decodes the Port ID from the event TRB (XHCI_PSC_EVT_PORT_ID, new in xhci.h), reads that port's PORTSC.CCS via a new xhci_port_regs() helper, and logs connect vs. disconnect. Acknowledges by writing back only PP (preserved) and CSC (the bit being cleared) -- PED/PR/other _C bits written 0 so nothing is accidentally disabled, reset, or silently cleared, matching the RW1C discipline already used for ERDP.EHB in 2d. Verified with the real target scenario via QMP hotplug on all three architectures: boot with the xHCI controller present but no USB device attached (confirmed zero port activity at ok>), then live attach/detach/re-attach of a virtual USB thumb drive (disk/usb-thumbdrive-test.img via usb-storage on xhci0.0). Full connect->disconnect->connect cycle confirmed clean (no port wedge) on amd64; single connect confirmed on aarch64 and riscv64. Still open: correlating Command Completion Events back to their issuing command, driving Enable Slot/Address Device from this connect path (currently only a boot-time smoke test), and the callback surface into Section U's higher-level code.

Design of Experiments (DoE) campaign data and analysis for the LithosAnanke kernel.
bare_metal/— the bare-metal DoE experiment: blind full-factorial 2⁴ runs measuring the L8 Jacquard mode selector's effect on the Steady-State Machine across amd64/aarch64/riscv64. Seeexperiments/bare_metal/README.mdfor the full directory layout (runs/,latest/,analysis/{charts,tables,report}).
Hosted-VM DoE campaigns (factorial/heartbeat/ablation studies) live under
