Q6 leaned toward nested for the right conclusion and the wrong reason. Its premise -- that a single region "reintroduces locking, the one mechanism this architecture has otherwise never wanted" -- is false. Every mutex in the kernel build is a no-op (shim.c:415); the kernel compiles STARFORTH_MINIMAL and the shim stubs dict_lock and tuning_lock out entirely. The architecture has not avoided locking, it has locking, inert. The cost Q6 weighs is currently zero, so Q6 cannot be decided on it. Decided nested on six other grounds, the strongest being SMP-readiness: nested keeps messages the only boundary-crossers, so no shared memory and no locks ever, whereas a single region would need real locks and the present no-op stubs would silently become a correctness hole. The most practical is that the outer level already exists and works (§20.1) -- single-region means discarding a working two-level structure. Also records a step-one finding that lands before any Stadium work: enabling timer interrupts introduces genuine ISR-vs-mainline concurrency where none exists today. Making the mutexes real would deadlock a single hart outright, since an ISR spinning on a lock the mainline holds can never be released. The top-half/bottom-half split of §18.4 is the answer, stated as a rule: Nothing in interrupt context may mutate Stadium structure. Ever. That constraint should be written at the stub site so the no-op is not later "fixed" into a spinlock. Opens: two capacities to size rather than one, and elasticity (§12 Q4 / §7 / §17.6c) becomes the live fork now that nesting makes capacity transfer real.

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 | |
|---|---|---|
| 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
# 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
