- Ruling (Captain Bob): per-slot locks, not "own path needs no lock" -- a lock only on the cross-slot side can't exclude an unlocked owner (Hermes release evicting a sender's cell while the sender admits). FABRIC-3.10.0 §3.6 amended. - StadiumVMQuota.lock covers the slot's lists, reservoir, consumed, word row and its cells. Word dispatch holds only its own slot lock for the whole dispatch (*_in_slot forms); peek-then-pull is one step. - g_lock_stadium: grant slot allocation (new slot published with release in_use) and the shared block table (ruled: the one shared-lock Stadium path). Taken before a slot lock. - Bitmap bytes set/cleared atomically (8 cells, possibly 8 slots). - Cross-slot writers moved under the owner's lock: Hermes decay (stadium_cell_decay), Hermes release ledger (stadium_evict_credit), session pin (stadium_cell_set_pin). stadium_conserved() one hold. - Word and block cell lookups check the cell is still this slot's. - Probe (removed), identical on all three ISAs: 10,746,599 of 10,746,616 word dispatches took exactly one lock (own slot), the 17 others all row growths; every live VM conserved; Hermes audit failures 0. - Findings reported: births/USE run a VM's words while another VM is the core's current VM (MC-3 claim must cover it); quota slots never released; owner admission can evict a live message cell (latent, 0). - Standard sequence on amd64/aarch64/riscv64: dict_hash set and G byte-identical, MINT/WIREBIND/USE ok, conservation true, 0 idle growth.

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.
