A block request with fewer than two values on the stack is refused; it had acted on whatever the stack ring held and stopped the node. Bare metal: when the kernel's chain takes the place of POST's block RAM the node's two buffers are emptied, so it no longer holds POST's copy of a block; and the chain's fast RAM is cleared, so a node cannot read what was in the kernel's heap. blocks.c is built with each test under that test's own warnings and sanitizers; it had been left out of both. The hosted link cleans its object directory first: it had linked the withdrawn store_v3.o left there from the day before. node.h and DECOMPOSITION.md D-19 no longer describe the message device or the four registers as current. MESH.md 8.5 records two findings for ruling: a node's own copy of a block, and a block read over a node's code. From a clean build: make -C v4 test, sanitize and hosted-check pass; amd64, aarch64 and riscv64 boot, POST 538 of 538, same hashes, blocks 1 and 2047 clean at the prompt: logs/20261007-085017, -085254, -085636.

src/starkernel/
LithosAnanke — the bare-metal UEFI kernel that boots StarForth directly on
hardware (amd64/aarch64/riscv64). Built only via Makefile.starkernel; the
only valid acceptance test is the three-arch QEMU boot (see
.claude/CLAUDE.md), never make test.
kernel_main.c— kernel entry point, driving the boot milestones (console init, PMM, VMM, interrupts, timers, kmalloc heap, VM bootstrap).repl.c— kernel REPL.doe_log.c— kernel-side DoE (Design of Experiments) metrics logging.
Subdirectories:
arch/{amd64,aarch64,riscv64}/— per-architecture support (APIC/GIC/ PLIC interrupt controller, timers, boot/ISR assembly).boot/— UEFI loader, ELF loading, kernel command-line parsing.capsule/— capsule birth/run/load/validate pipeline.hal/— hardware-abstraction-layer implementation (console, framebuffer, VT100, memory, host services).hash/— XXHash64 content-addressing implementation.math/— kernel-build Q48.16 fixed-point arithmetic.memory/— physical/virtual memory managers and the kernel heap.pci/— PCI bus enumeration.virtio/— VirtIO block device driver.vm/— kernel VM subsystem (bootstrap, core interpreter, parity logging, capsule arena).
