Replaces the crashed NVRAM approach entirely. New include/starkernel/zuse_cert_devblock.h: a standalone on-disk record (magic + version + 32-byte seed + 32-byte pubkey + a real CRC-64/ISO from day one, same discipline homeblocks_sig_t established) occupying devblock_from_top=0 of the fence. Its own header, not inlined at the boot call site, since the still-open MINT word will be a second consumer of this exact format. kernel_main.c's mint-or-load logic now reads the fence, installs an existing valid cert, or mints fresh via virtio_rng+ed25519_keygen and writes it. Runs right after virtio_rng_init(), before capsule_birth_mama() -- unlike the crashed NVRAM attempt, raw block I/O against Artemis's already-proven device has no boot-timing risk, so the earlier "re-invoke ACL-ZUSE-BOOT after Mama birth" workaround is gone; ACL.4th's self-activating ACL-ZUSE-BOOT sees a correct cert on its one ordinary pass. Verified independently across every real scenario, never trusting the kernel's own report: fresh mint decodes correctly on disk with a CRC confirmed by a from-scratch Python re-implementation of the algorithm; a reboot without reformatting loads back byte-for-byte identical seed/pubkey (genuinely "mint once, ever"); a pre-fence volume refuses cleanly (no crash, no silent data loss, honest "not persistent" reporting); the real, untouched disk/artemis.img exercises the same graceful-refusal path identically on all three architectures. Phase 8's core arc is now functionally complete: real entropy -> real signing -> real anti-file block-native persistence -> a first-boot mint that survives reboots. Still open: the ongoing MINT word for minting additional regular users. Documented in FABRIC-3.md.

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.
