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
modules, 0 failures.
