Not yet accepted (plan 2026-10-29-stick-5, Task 2, step 3). - gpt.c: the writer, gpt_grow_last() -- the backup entry array and header to the disk's end, the last partition to the last usable sector (whole MiB, capped), both headers' CRCs, the backup before the primary, the protective MBR's size; gpt_alternate_lba(). - sk_v4_grow.c: the volume grown to its partition -- its fence (the Artemis signature, Zuse's genesis marker) moved to the new top, the header last; the partition grown no further than the BAM tracks (the block subsystem places the fence by the device's size, so a volume must fill it). - sk_v4_identity.c: a stick of 8 GB or more whose GPT ends short of the disk is grown before its partitions are opened; "Artemis: grown to fill the stick" / "under 8 GB -- not grown" / "past 256 GiB ... left unused". - block_subsystem: blk_volume_compute_totals() (compute_totals_from_B, public) and blk_subsys_set_format_bam_for(); v3's behaviour unchanged. - mkartemis --bam-for, mkdiskimage.sh --bam-for, kernel/Makefile STICK_GROW_MIN_BYTES / STICK_ARTEMIS_CAP_GIB: the stick's and data stick's Artemis BAM sized for 256 GiB (6144 devblocks). STICK.md 5a: 256 GiB (R1). After: stick_grow PASS (16 GiB: 12129370 user blocks, 8 s POST to prompt; second boot not grown, recognised; sfdisk --verify: no errors), stick_small PASS, check_images.sh PASS.

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).
