Robert Allan JamesandClaude Sonnet 5 c1360df2d1 proof/: add StarForth_Block_Words.thy (SCR only)
block_words.c is categorically different from every file covered so far in
this sweep: every other word_source file operates on pure per-VM internal
state already in vm_state (data_stack/return_stack/memory/dictionary).
block_words.c sits on top of a real disk-backed I/O subsystem
(block_subsystem.h) plus a per-VM in-memory cache of it
(vm->blk_vm_lbn/blk_vm_cbuf/blk_vm_dirty/blk_vm_next), none of which are
in vm_state.

Only SCR is self-contained (just needs vm->scr_addr, added to vm_state
the same way here/ecw_nesting were for earlier files). The other 11 words
are deferred for three reasons documented in the theory header: the
block-window cache subsystem (a modeling project on the scale of the
deferred TIB input subsystem, not a one-word extension), real disk I/O via
block_subsystem.h, and recursive vm_interpret()/printf() in LOAD/LIST/
THRU/-->.

Noted in passing: blk_vm_evict/blk_vm_flush_all's own comments document a
real raw-pointer-lifetime bug (stale C buffer pointers after block-
subsystem struct-copy eviction) that was already found and fixed by hand
in the C, before this suite ever looked at the file -- not an open issue,
just worth recording as prior art for exactly the class of bug this sweep
exists to catch.

30 theory files verify with zero errors.

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
