Who runs next is now sk_vm_switch_decide(): among participants with work (pending kernel-Hermes mail, parked mid-task, or Hera with console input), the coolest by VM-physics heat; ties with the incumbent keep the incumbent, ties among candidates go to the longest waiting (unique wait stamps). No scheduler state, no timer: heartbeat_tick() no longer touches switching, readiness/threshold/has_work/take_pending removed. Decided at owned word checkpoints (colon words and, new, between top-level words) after a beat or new mail, at the trampoline between messages, and at Hera's idle point in the console poll loops. The idle pump skips participants (G3 closed for them): the WIREBIND relay is delivered by a real switch to rajames~user. Probe (restored away): relay via switch Hera->rajames~user->Hera on all three ISAs, parked saved_sp inside own stack, walk-order disagreements 0 over tens of millions of decisions, 0 bytes idle log growth. Acceptance: dict_hash unchanged, relay 3, no faults. Rulings: C-3, C-5 as proposed; C-4 taken as (alpha), consequence recorded. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
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.
