rajamesandClaude Opus 5.5 6015c87157 revert(v4.0.0): step 6d, the wait, is backed out -- two reviews found it unsound
Ruled 2026-10-08.  The engine, the nucleus and their tests are as they
were at dfabfa46, before step 6d; the code of the wait and its tests are
in history at 075385ab..2cf37aab.  The limit of MESH.md 7b.7 stands: a
node that is stuck can hold up its neighbours until Hera kills it.

MESH.md 7c is kept as the record of the design as approved, and 7c.6 says
what was built, what the two reviews found, the cause the findings share
-- a node's message machinery runs on the stacks its text is using, and a
fault abandons whatever was in progress -- and what a second attempt
must settle before anything is built.

Kept from it, in hosted-check: a line that leaves 29 values on the stack,
and WORDS with 26 values on it.  Both hung the products at some commit of
the wait.

make -C v4 test and sanitize at both widths, hosted-check, lint; three
bare-metal boots typing both.  POST 538 of 538, word_count=317,
dict_hash=0xc0769523a47b7dc3 on all six: the hash of step 6c's code.

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.


Products

StarForth v4 moves the engine onto a 32-instruction core derived from Chuck Moore's F18 (docs/v4.0.0/). With it, this repository carries three products, not one:

Product What it is
Hosted StarForth F18 The v4 engine as a native Linux build, for amd64, arm64 and riscv64, on real hardware.
FPGA StarForth F18 A 32-bit build of the same engine loaded into the FPGA. It is the gateway to the rest: the foundation everything else is built up from.
StarshipOS The bare-metal product: LithosAnanke running the v4 F18 engine.

FORTH-79 is recomposed on the F18 engine and stored as a capsule; the StarshipOS-specific vocabulary gets the same treatment. The source tree will be reorganised around this split.

v3 remains the reference system until v4 meets its acceptance criteria (docs/v4.0.0/JUSTIFICATION.md §16). Everything below describes v3 as it stands today.


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 superuser zuse)ok>). Phases 1–7 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

# 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
