Claude cdf9cb24aa FABRIC-3.5.md §XXXV: pre-mortem -- two new design gaps, one hypothesis weakened
Assume failure six months on and work backwards, grounded in this
project's own failure record rather than generic risk.

Puts the dominant failure mode first, with four independent instances:
things here fail without saying anything -- an identical serial log for a
switch storm and a healthy idle REPL, a console-name mismatch that
quietly never relays, 6 of 9 identities silently not attaching, and FORTH
silently dropping a definition that references an undefined word.

The principal finding is a design gap rather than a risk. §VIII's sinking
latch was conceived when Hermes was a Stadium patron that could degrade.
Kernel-Hermes is not admitted -- stadium_admit() runs only on birth -- so
it has no heat, no TTL, no eviction and no compudynamic death. Its real
failure modes are a panic, which halts instantly and gives the fleet no
window at all, or allocation refusal, which is degraded but not dying and
would be wrong to latch irreversibly. §VII's ladder does not apply either,
since rung 2 is a from-scratch BIRTH and BIRTH births VMs. So the failure
story for the one component that cannot emit SOS is undesigned, and
retiring §VIII is a legitimate option rather than a tidiness problem.

Second finding: SK_SWITCH_MAX_SLOTS is 16, which was reasonable when the
switcher was one of two ways a VM got control. §XXXII made it the only
one, so 16 becomes a hard ceiling on the fleet the moment that ruling
lands, against §XXII's own note that the fleet is headed toward hundreds
of VMs. This is the pump story repeating one layer up, findable on paper
this time.

Records a hypothesis that weakened on inspection rather than pushing it:
K verification is vm_physics_conserved() in capsule_vm_physics.c, exposed
as VM-CONSERVED?, independent of the DoE, which only reports it. The
capability survives a DoE rewrite; only the continuous per-tick record
does not, so Stage B needs its own deterministic check loop.

Also flags that Hestia's ownership is conventional and therefore
checkable -- the framebuffer primitives must be registered to her alone
-- and that the Category A strip should precede the DoE rewrite while the
campaign that would catch a bad strip still runs.

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 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

# 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
