rajamesandClaude Opus 5.5 9af442f793 feat(v4.0.0): nodes that talk -- ports, a node born empty, and the fabric
MESH.md step 1, in the engine, which knows nothing of StarForth or of any
kernel.

- node: V4_PORTS ports (8), a build parameter; "any port" and the port the
  last such read came from; a read blocks until the neighbour writes, as a
  write blocks until the neighbour reads; v4_node_born: empty, P at "any
  port"
- exec: a fetch from a port -- @ @b @+ @p, or of an instruction word when P
  is a port -- waits for a word; a node executes what arrives at a port
  without advancing P; a blocked node goes on from the slot it stopped at
- fabric: the nodes there are and the table of how their ports are wired,
  both changed while the nodes run; devices on a port; asleep and awake; a
  step is every unblocked node executing one instruction word, then every
  write with a reader waiting being handed over
- DECOMPOSITION.md section 6: four named ports withdrawn for V4_PORTS
  numbered ones and wiring as data, as ruled

Verified: tests/test_fabric.c, 53 checks at both widths: two nodes exchange
words; an empty node is filled through its port by a device, and by another
node, and runs what it was sent; a word is passed on by a node in between;
a waiting node executes nothing; the wiring is changed while they run; a
node is put to sleep, woken and removed while looping; a node is born while
others run; the fabric is given more room.  make -C v4 test and make -C v4
sanitize pass.  The single-node products are unchanged: hosted-check on
three ISAs, and clean qemu with STARFORTH_V4=1 on amd64, aarch64 and
riscv64 with lines typed at each prompt (logs/20261006-074907, -075150,
-075532).

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
