- block_subsystem.c (vendored): every public function's body becomes a static *_locked function; bodies call each other only through the _locked forms, breaking the internal cycles (relocate, meta relocate, migration scan, firsttouch, the meta accessors). Thin public wrappers take g_lock_block under __STARKERNEL__; hosted build has no lock and still builds clean. - Lock order: hermes, switch, registry, doe, log, block, console, heap, vmm, pmm (Stadium, MC-0d, above block). - Documented, not coverable by this lock: blk_get_buffer() pointers are used after release -- block-buffer ownership across cores is open for MC-3. - Probe (removed): block lock balances on all three ISAs (2,057-2,379 acquisitions), 0 recursions, 0 held at switch; vblk_io timeouts (0/0/4 probe, 0/0/2 acceptance) within the pre-lock riscv64 baseline of 0-6. - Standard sequence on amd64/aarch64/riscv64: hashes and G byte-identical to MC-0b, MINT/WIREBIND/USE ok, conservation true, 0 idle growth. - FABRIC-3.10.8 §3.2 wording fix; lock order noted as checked by inspection only.

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.
