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.

include/starkernel/
Headers for LithosAnanke, the bare-metal UEFI kernel (src/starkernel/).
Built only via Makefile.starkernel; gated by __STARKERNEL__ when shared
with hosted code.
uefi.h— UEFI protocol/type definitions consumed by the loader.elf64.h,elf_loader.h— ELF64 parsing and kernel-image loading.boot_info_offsets.h— struct-offset constants shared between the assembly bootstrap and the C boot path.arch.h,apic.h,timer.h— architecture init, APIC interrupt controller, timer (TSC/HPET/APIC, 100 Hz heartbeat).console.h,framebuffer.h,vt100.h— UART 16550 console, framebuffer driver, and VT100 terminal emulation over the framebuffer.pmm.h,vmm.h,kmalloc.h— physical memory manager (bitmap allocator), 4-level x86_64 paging, kernel heap allocator.pci.h,virtio_blk.h— PCI enumeration and the VirtIO block device driver (disk backend for the kernel block subsystem).capsule.h,capsule_birth.h,capsule_loader.h,capsule_run.h,capsule_vm_physics.h,capsule_generated.h— capsule system types, birth protocol, physics-runtime capsule bindings, and the build-time- generated capsule directory (seetools/mkcapsule.c).kernel_args.h,cmdline.h— boot-time kernel argument parsing (starforth.cfg/ command line).repl.h— kernel REPL.log.h,doe_log.h— kernel logging and DoE metrics logging.q48_16.h— kernel-build copy of Q48.16 fixed-point arithmetic.xxhash64.h— content-addressing hash used for capsule IDs.hal_memory.h— hardware-abstraction-layer memory interface.
Subdirectories:
hal/— top-level hardware-abstraction-layer interface.vm/— kernel VM subsystem headers (capsule arena, parity logging, bootstrap wiring).freestanding/— minimal libc-shim headers (assert.h,ctype.h,errno.h,inttypes.h,math.h,sched.h,signal.h,stdio.h,stdlib.h,string.h,time.h,sys/time.h,sys/types.h) for building shared VM code in the freestanding kernel environment, where no real libc is available.
