Executed on the golden model as written, and correct: <, =, D<, 2OVER,
and Q.=, Q.<, Q.0= (the D=, D<, D0= words).
Fixed, because they could not work under D-2 or were wrong:
- DMAX, DMIN: 2OVER 2OVER D< needs 8 data cells plus D<'s 2, the whole
10-deep data stack, so both failed on every case once the caller held
anything. Rewritten on a new call-free helper
(D<) ( d1 d2 -- d1 d2 flag )
which compares copies of the high cells, then the low cells unsigned
on a tie, with in-line sign tests; DMAX and DMIN then drop the loser.
- 2SWAP: ROT and SWAP written in line. Return headroom 2 -> 4, which
also lifts 2OVER 1 -> 3 and Q.> 1 -> 2.
- Q.>: section 5.26 gave SWAP D<, which swaps single cells; it was wrong
in 11702 of 20169 cases. Now 2SWAP D<.
Checked at 32- and 64-bit cells, optimised and ASan+UBSan: every
edge-vector quadruple (50625) for D<, (D<), 2SWAP, 2OVER, DMAX and DMIN;
Q comparisons on every pair of 13 edge Q values plus 20000 pseudo-random
pairs weighted to ties and one-bit differences, signed (D-8) and against
v3's unsigned comparisons where both values have the same sign.
Mutating any (D<) branch or subtraction fails 700+ checks.
The new fatal-UBSan setting caught a test-side array overflow in the
headroom probe (results buffer sized 4, six needed); fixed.

LithosAnanke v2.0.1
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 | |
|---|---|---|
| M0–M6 | 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 1–7) | 🔄 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 superuserzuse)ok>). Phases 1–7 complete (C infrastructure, FORTH policy layer,zusebootstrap 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
# One boot image per physical target (output: build/boards/<board>/)
make boot_image TARGET=SER5 # Beelink SER5 -- GPT/ESP, BOOTX64.EFI
make boot_image TARGET=RASPI # Raspberry Pi 5 -- FAT, config.txt + kernel_2712.img + DTB
make boot_image TARGET=MILKV # Milk-V Mars -- GPT/ESP, BOOTRISCV64.EFI (U-Boot bootefi)
make boot_image TARGET=ZYNQ7020 # Zynq-7020 -- ARMv7 port in progress
make boards # list boards
# The same TARGET drives all, docs and clean (make help)
make # every board with a kernel port + hosted v3 + the book
make TARGET=RASPI # one board's image + build/docs/LithosAnanke-raspi.pdf
make docs # build/docs/LithosAnanke.pdf (LaTeX master: docs/book/main.tex)
make clean TARGET=RASPI # that board's outputs and build/aarch64/kernel
make clean # all of build/ except build/cache/
# Build kernel (requires cross-compilation toolchain, or native gcc)
make -f kernel/Makefile ARCH=amd64
# Run in QEMU with OVMF
make -f kernel/Makefile qemu
# Other architectures
make -f kernel/Makefile ARCH=aarch64 qemu
make -f kernel/Makefile ARCH=riscv64 qemu
Artifacts: build/amd64/kernel/starkernel_loader.efi · build/amd64/kernel/starkernel_kernel.elf
Tree: kernel/ (LithosAnanke: Makefile, src/, include/starkernel/, linker/),
v3/ (StarForth v3 engine and hosted build: Makefile, src/, include/),
v4/ (StarForth v4, see docs/v4.0.0/), boards/<board>/ (board.mk + boot files).
Every makefile runs from the repo root; the root Makefile forwards any other goal to
v3/Makefile (hosted build).
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 kernel/Makefile uses the same defaults it always has unless
you opt in:
make -f kernel/Makefile ARCH=amd64 menuconfig
make -f kernel/Makefile ARCH=amd64 kernel_amd64_defconfig
