Robert Allan JamesandClaude Sonnet 5 b42308762b FABRIC.md: 4.4g stays open (reorder not viable), add urgent item 4.6 (-O0 kernel build)
Attempted 4.4g's console_fb_init() reorder twice this session: once bare,
once with the fb_scroll_rows() volatile fix applied. Both stalled boot
indefinitely (12,000+ lines logged, still running after 3 minutes vs. a
normal few-second boot) instead of completing. Root cause traced past the
scroll fix to Makefile.starkernel building the kernel at -O0 -- no
optimization flag has ever been configured there, verified against the
file's full git history (17 commits, only ever one unrelated host-tool -O2
line). Both the kernel's own vendored hosted Makefile and the standalone
StarForth repo's Makefile default to -O2 (up to -O3/-flto on faster
targets); Makefile.starkernel was written fresh for the bare-metal target
and never got that ladder.

Documented as new item 4.6: enabling optimization is not a safe drop-in
change on its own. Found one confirmed, isolated correctness hazard first --
TimeTrustState.ticks (timer.h:90) is written directly in ISR context on all
three architectures (heartbeat.c:163) and read directly by mainline
(heartbeat.c:200-202, including a busy-wait in kernel_main.c:880) without
being volatile, unlike every other ISR-shared global checked
(g_spurious_count, g_plic_claim_count, g_pending_counter/g_pending_valid/
g_adaptive_period_ns are all correctly volatile already). Reverted the
console_fb_init() reorder itself (uncommitted, so a plain git restore) --
4.4g stays open pending 4.6.

Both the reorder attempts' logs (stalled, never reached ok>) and this
session's routine three-arch artifacts (capsules/BLOCK_MAP.md, disk/
artemis.img, DOE CSV) are committed as audit trail per CLAUDE.md.

LithosAnanke v1.5.4

UEFI-bootable FORTH microkernel. Boots from firmware, initialises memory and interrupts, then runs the StarForth VM as its sole userspace runtime. No libc. No OS. Just stone and necessity.

Lithos (foundation) + Ananke (necessity) — the kernel under StarshipOS.


Status — M7.1 (Capsule System · Multi-VM Fleet)

Milestone Status
M0M6 UEFI boot · PMM · VMM · IDT · APIC · heap · framebuffer VT100 console (v1.5.1-FINAL) Complete
M7 StarForth VM integration + parity validation Complete
M7.1 Capsule birth protocol · Mama FORTH vocabulary · Tripod multi-VM fleet (Hermes/Artemis) · Word-level ACL (Phases 17) 🔄 In Progress
M8 REPL — keyboard input, interactive Forth Planned
M9 Block storage — AHCI driver Planned

POST at boot: parity hash verified across amd64/aarch64/riscv64 · Mama capsule dictionary: 453 words

What's live in M7.1

  • Tripod — a named multi-VM fleet (Hera the Mama VM, Artemis, two Hermes instances) births, runs, and re-births independently, verified booting live pre-REPL on all three architectures.
  • Hermes — a 17-block inter-VM messaging/channel layer between fleet members, with async delivery and channel negotiation.
  • Artemis — a Block Allocation Map (BAM) storage subsystem with Q48.16 block-heat tracking and cooldown/reclamation (ART-COOL/ART-REAP).
  • Word-level ACL — every dictionary entry carries a TTL/allow/mode/pin access-control record. Strict, TTL, and pinned modes; two console layers (emergency ok> and superuser zuse)ok>). Phases 17 complete (C infrastructure, FORTH policy layer, zuse bootstrap superuser, Isabelle proof stubs, kernel parity); Phase 8 (Ed25519 PKI / thumbdrive challenge-response) is the only item remaining. Measured overhead once active on every check: +0.0054%+0.0088%, CV = 0.000%, across a 3×3 Latin-square DoE campaign (architecture × seed × 30 replicates) — three orders of magnitude below the measurement floor.
  • VM Fleet Attractor physics — the L8 Jacquard mode selector now has a real per-VM heat channel into fleet-wide tuning, replacing hardcoded compudynamics constants with a dynamically-inferred rate.
  • Kconfig build configuration — every physics/heartbeat/pipelining/ kernel-only tuning knob (~40 total) is now a discoverable, optional Kconfig symbol shared with the hosted VM build. See Quick Start below.

Quick Start

# Build kernel (requires cross-compilation toolchain, or native gcc)
make -f Makefile.starkernel ARCH=amd64

# Run in QEMU with OVMF
make -f Makefile.starkernel qemu

# Other architectures
make -f Makefile.starkernel ARCH=aarch64 qemu
make -f Makefile.starkernel ARCH=riscv64 qemu

Artifacts: build/amd64/kernel/starkernel_loader.efi · build/amd64/kernel/starkernel_kernel.elf

For the hosted VM by itself (Linux, no cross-compiler needed, no bare-metal tooling): see the separate StarForth repository — LithosAnanke used to be a branch inside that repo, now it's its own project with its own master.

Build configuration (optional)

Every kernel-only knob (STARFORTH_ENABLE_VM, PARITY_MODE, the shared physics/heartbeat family, etc.) is an optional Kconfig symbol — a plain make -f Makefile.starkernel uses the same defaults it always has unless you opt in:

make -f Makefile.starkernel ARCH=amd64 menuconfig
make -f Makefile.starkernel ARCH=amd64 kernel_amd64_defconfig
