Robert Allan JamesandClaude Sonnet 5 431bcb1f34 Milestone 6: root CA generated, snakeoil intermediate embedded, DER parser
Root CA + snakeoil intermediate generated entirely offline
(/home/rajames/CLionProjects/lithosananke-ca/, outside this repo,
private keys chmod 600) per this milestone's own requirement: Ed25519,
root self-signed 20-year validity, intermediate real-CA-signed
(CA:TRUE, pathlen:0), chain verified via openssl.

Snakeoil intermediate embedded as a capsule (capsules/pki/
snakeoil-intermediate.der) -- confirmed the font-capsule precedent
needed zero new infrastructure, any non-.4th file under capsules/
embeds verbatim already.

New x509_ed25519.c: a from-scratch, narrow DER walker (not general
ASN.1/X.509, per this milestone's design decision) extracting the raw
Ed25519 pubkey from a cert's SubjectPublicKeyInfo -- handles the
optional v3 version field, verifies the AlgorithmIdentifier OID is
Ed25519 rather than assuming, handles both DER length forms. Verified
against ground truth: the extracted key from the real embedded cert
matches openssl's own reported pubkey byte-for-byte; refusal path
checked against truncated/garbage/empty/wrong-algorithm (real RSA cert)
input. Compiles clean on all three architectures.

Still open: mkcapsule signing step, wiring ed25519_verify() into
capsule_birth.c's three validate call sites (landing warn-only first,
per decision -- a bug here could stop every capsule from birthing,
including Mama's own, on all three arches), and the BLOCK_MAP.md
signature-status column. 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 (see tools/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.
