Added HERMES-CHANNEL-OPEN? ( req-hi req-lo -- allow? ) at capsules/ACL.4th block 4008 (default: approve everything) -- the one word policy authors edit. sk_hermes_channel_open_policy(VM*, VMUuid) (kernel_hermes.h/.c) is the C-side query that calls it via plain word-dispatch against the target VM's own dictionary/stack, never vm_interpret() (avoids task 3.4's input-buffer cursor hazard entirely) and never decides the answer itself. Fails closed: no policy word, a policy error, or stack underflow all deny, matching CLAUDE.md's posture that absence of policy must never mean "always allow." Two real bugs found and fixed before this was called done: missing current_executing_entry assignment before calling the word's func pointer (colon words silently no-op without it, vm_core.c:730 -- no crash, just a wrong answer); and a second FAIL with debug instrumentation still in place whose precise cause isn't reconstructable, since no intermediate commit exists for that attempt. Self-test proves the task's check four ways against the same unchanged C function: default approve, live redefinition to deny (zero C change), restore, and a VM with no ACL.4th loaded at all (fail closed). A fifth check wires the result into task 3.6's sk_hermes_channel_respond() end to end: a denied policy produces a NACK and no channel, ledger/stadium_conserved() holding throughout. Scope, per Captain Bob's ruling: closes with the query built and proven; sk_hermes_channel_respond() still takes a caller-supplied approved bool rather than calling the policy internally. Wiring a real channel-open call site to only this query is deferred to whichever later task first needs a live decision. dict_hash identical across amd64/aarch64/riscv64 for every VM, zero UNKNOWN WORD, mkcapsule --lint clean (38 files, 0 violations).

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).
