The increment 2 final review's minors 1-4 (Captain Bob, 2026-10-27: "fix 1-4"): 1. A protective MBR with no "EFI PART" header is GPT_BAD, not GPT_NONE: the MBR says it is a GPT disk, and a GPT disk is never attached whole. 2. A disk whose block 0 cannot be read is GPT_EIO: "GPT: a USB drive could not be read -- not used", nothing attached (it was read raw, attached whole, and a raw Zuse drive behind it logged her in). 3. The entry array's LBA is checked against the disk's size directly. 4. gpt_bad_entries: the entry array changed, the header valid -- refused. Harness modes gpt_no_header, gpt_read_error (blkdebug EIO on sector 0), gpt_bad_entries. The plan carries the amendment. Red (amd64): gpt_no_header 070335, gpt_read_error 070717 FAIL; gpt_bad_entries 070048 PASS (existing check, now pinned). Green: every GPT mode on amd64 071113-072933; gpt_zuse, gpt_read_error, gpt_no_header on aarch64 073222-074047 and riscv64 074526-075535; the identity gate's and increment 1's sessions 080036-082345, emergency 083130 (082635 was run without EMERGENCY_CONSOLE_ENABLED=1 -- a harness invocation error). Accepted: suite EXIT 0; 093121, 093352, 093750, POST 538/538, dict_hash 0xfec8c47cfc6f437f; test-32, 0 failures. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
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).
See include/starkernel/README.md for the corresponding headers.
