qemu-stick boots the amd64 stick image (build/boards/pc/lithos-pc.img,
copied per run) as a USB drive on q35, exactly as hardware would.
DATASTICK=1 adds the data stick to any qemu run as a second USB drive.
qemu_session.py gains --target and the stick_boot and datastick modes.
Checks: stick_boot (the stick's own identity partition attaches, headless
on a blank identity); datastick on amd64/aarch64/riscv64 (both drives
found, the data stick's 500 MiB identity attaches); the seven GPT modes,
the identity-gate and increment 1 sessions, emergency; the suite; three
acceptance boots to [zuse@Hera] ok> with POST 538/538 and
dict_hash=0xfec8c47cfc6f437f; test-32 0 failures.

Captain Bob, 2026-10-26: sized for an off-the-shelf thumb drive, "a minimum
and then ... no max or reasonable max size"; "all to Artemis, identity stays
at 500 MiB". The image is 2 GiB (ESP 64 MiB, identity 500 MiB, Artemis the
rest); the minimum stick 8 GB; at first boot Artemis grows to fill the stick,
up to 2 TiB, writing metadata only (GPT, volume header, free map, fence); a
stick under 8 GB is not grown. With genesis, increment 5; the GPT writer is
INSTALL's too.

Captain Bob, 2026-10-26: "64 megabytes does not need to be an engraved in
stone size ... start maybe 500 megabytes." Sizes are set in kernel/Makefile
and are not fixed by the formats.

One GPT stick that is the whole OS: ESP, a StarshipOS identity partition and
a StarshipOS Artemis partition; a splash until Zuse logs in, automatically;
each stick mints its own Zuse on first boot; try-it writes persist on the
stick until INSTALL; pulling it goes headless. GPT comes back for boot media
and installed disks (overturns FABRIC-2.md F.8 for those); system=v3 is
refused on a stick; every clean qemu boot uses a GPT data stick over USB,
virtio Artemis leaves v4. Approved by Captain Bob 2026-10-26. First of three
designs (then INSTALL, then DOE/SDK/demos); ahead of ENGINE step 4 Part A.
