The global state becomes struct blk_chain, reached through a current pointer: blk_chain_default, blk_chain_new, blk_chain_select. Nothing that uses the one chain changes. blk_subsys_init loses its VM argument, which was stored and never used. docs/v4.0.0/MESH.md 8.4. Accepted on the v3 configuration: amd64, aarch64 and riscv64 reach the zuse prompt, no UNKNOWN WORD, PARITY:M7.1a hash 0x08873e0f44b7cb2a on all three, as on 2026-10-03. logs/20261006-202918, -203036, -203230.

src/starkernel/vm/
Kernel-side StarForth VM subsystem.
vm_core.c— kernel port of the core interpreter loop.vm_runtime.c— kernel VM runtime support.vm_bootstrap.c— kernel VM bootstrap (distinct frombootstrap/sk_vm_bootstrap.c, which owns the higher-level subsystem wiring called fromkernel_main.c).arena.c— capsule arena allocator (fixed-region allocation for capsule payload data).parity.c— birth/execution parity logging (VM ID + capsule hash + dictionary hash), enabling offline determinism verification.alloc_kernel.c— the kernel-side implementation of the VM's allocator interface actually referenced byMakefile.starkernel's build (seesrc/platform/README.mdfor a note on a second, unwired copy).q48_stubs.c— deliberate no-op stubs forq48_from_double()/q48_to_double()in the freestanding kernel build, where floating point is unavailable; always returns zero, safe because shared VM code only uses these results for logging/diagnostic paths that are inactive in the kernel build.vm_internal.h— internal-only declarations shared across this directory's files.
Subdirectories:
bootstrap/sk_vm_bootstrap.c— owns VM init + capsule loading wiring, called fromkernel_main.c;kernel_main.citself only owns hardware milestones.host/shim.c— host-service shim bridging the kernel VM tosrc/starkernel/hal/host_services.c.
