The stick, increment 2 (plan 2026-10-26-stick-2-gpt-reader; docs/v4.0.0/
STICK.md 3 and 4: GPT for boot media and installed disks). kernel/src/gpt.c:
a CRC-32; gpt_read(), which checks the protective MBR, the primary header and
the partition-entry array (both CRCs, the revision, the sizes, the geometry);
and a partition as a blkio device, refusing blocks past its end. The two
StarshipOS partition types: identity 23BEBFE1-4817-4CF3-A537-9069BF159788,
Artemis BCD7B586-1C8E-4EEF-86A3-273A8D8EE624.
The v4 drive path: a GPT disk is used only through its StarshipOS identity
partition, and that partition -- never the disk -- is given to the block
subsystem, in a raw identity drive's place; a GPT disk with no StarshipOS
partition, or a damaged table ("GPT: a USB drive has a damaged partition
table -- not used"), is not attached (Captain Bob's ruling on the plan); a
disk with no GPT is read raw, as always. Pulling the drive detaches the
partition and ends her session. Reads only.
Red (amd64): gpt_zuse 193158, gpt_hotplug 193804, gpt_foreign 194713,
gpt_bad_crc 194947. Green: 195409, 195627, 195854, 200136; gpt_zuse aarch64
200424, riscv64 200839 (the 64 MiB partition attached, 48724 user blocks,
not the 72 MiB disk); the identity gate's and increment 1's sessions,
201119-203403, all pass.
Accepted (with the KERNEL_ARGS fix that follows): suite EXIT 0; 214300,
214507, 214911, POST 538/538, dict_hash 0xfec8c47cfc6f437f; test-32, 39

with hosted code.
uefi.h— UEFI protocol/type definitions consumed by the loader.elf64.h,elf_loader.h— ELF64 parsing and kernel-image loading.boot_info_offsets.h— struct-offset constants shared between the assembly bootstrap and the C boot path.arch.h,apic.h,timer.h— architecture init, APIC interrupt controller, timer (TSC/HPET/APIC, 100 Hz heartbeat).console.h,framebuffer.h,vt100.h— UART 16550 console, framebuffer driver, and VT100 terminal emulation over the framebuffer.pmm.h,vmm.h,kmalloc.h— physical memory manager (bitmap allocator), 4-level x86_64 paging, kernel heap allocator.pci.h,virtio_blk.h— PCI enumeration and the VirtIO block device driver (disk backend for the kernel block subsystem).capsule.h,capsule_birth.h,capsule_loader.h,capsule_run.h,capsule_vm_physics.h,capsule_generated.h— capsule system types, birth protocol, physics-runtime capsule bindings, and the build-time- generated capsule directory (seetools/mkcapsule.c).kernel_args.h,cmdline.h— boot-time kernel argument parsing (starforth.cfg/ command line).repl.h— kernel REPL.log.h,doe_log.h— kernel logging and DoE metrics logging.q48_16.h— kernel-build copy of Q48.16 fixed-point arithmetic.xxhash64.h— content-addressing hash used for capsule IDs.hal_memory.h— hardware-abstraction-layer memory interface.
Subdirectories:
hal/— top-level hardware-abstraction-layer interface.vm/— kernel VM subsystem headers (capsule arena, parity logging, bootstrap wiring).freestanding/— minimal libc-shim headers (assert.h,ctype.h,errno.h,inttypes.h,math.h,sched.h,signal.h,stdio.h,stdlib.h,string.h,time.h,sys/time.h,sys/types.h) for building shared VM code in the freestanding kernel environment, where no real libc is available.
