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.

Plan 2026-10-29-stick-5, Task 2, steps 1-2:
- qemu_session.py: --stick-gib N (the session's copy of the stick extended,
sparse); modes stick_grow (16 GiB: grown, over 12000000 user blocks, the
prompt, the first boot's time; the second boot of the same copy not grown
again; sfdisk --verify clean) and stick_small (4 GiB: under 8 GB, not grown,
said so).
- kernel/Makefile: STICK_GIB and STICK_FRESH on qemu-stick, for those.
- check_images.sh: the PC stick's and data stick's Artemis BAM sized for the
256 GiB cap (6144 devblocks).
Before the change: stick_grow FAIL (no growth line, 1137649 user blocks,
sfdisk: the backup GPT not at the end); stick_small FAIL (no line);
check_images.sh FAIL on the two BAM checks only.

Task 1 of plan 2026-10-29-stick-5, accepted in full:
- amd64, aarch64, riscv64: PARITY:V4_POST tests=538 pass=538 fail=0,
POST: PASSED, [zuse@Hera] ok>; dict_hash 0xfec8c47cfc6f437f on the three
- the PC stick loaded high: 538/538, POST: PASSED, the prompt
- make -C v4 test-32: 39 programs, 0 failures
The logs of the acceptance boots (aarch64 044253, riscv64 044558, the stick
high 044725; amd64 044115 is already in), the four accept-*.txt verdicts and
test-32's output. The plan's Task 1 steps ticked; FABRIC-3 XLVIII.8.

Work in progress on StarForth-v4.0.0; not yet accepted (plan
2026-10-29-stick-5, Task 1).
- zuse_genesis_marker.h: the marker's version 2 -- the proxy's key and the
real Zuse's -- beside version 1.
- capsule_zuse_boot.c: capsule_zuse_boot_check_key() (the identity-record
half of the check) and capsule_zuse_boot_genesis_mint() (the mint half of
v3's genesis) split out; v3's two callers unchanged in behaviour.
- sk_v4_marker.c: the v4 boot reads version 1 as a proxy with no real Zuse,
and writes version 2.
- sk_v4_identity.c: no marker and a blank identity partition -> genesis:
mint, read back, then the marker; the proxy logs in. A marker with a real
key: no session for the proxy (the fixed screen is Task 5).
- qemu_session.py: boot()/shutdown(), so a mode can boot twice; modes
genesis and stick_genesis; stick_boot now expects genesis and the prompt.
Logs: genesis on amd64 before the change (both boots: "no genesis on this
disk", FAIL) and after (minted, then recognised: PASS). The DoE CSV of
032532 is from a run whose QEMU never started (no display; its empty log
directory was removed).

ci/pki/starshipos-root-ca.pem, made on the CI box by make-ca.sh

in starshipos-root-ca.sha256. Verified: self-signed, CA:TRUE, and it issued
capsules/pki/starshipos-intermediate.der (openssl verify: OK). Every
release attaches it (gitea-release), and the Downloads page shows its
fingerprint; it is also the anchor #139 would build into the kernel.

- scripts/nightly.sh images builds the PC's USB stick too (make boot_image
TARGET=PC -> pc-stick.img.xz, in SHA256SUMS); publish sends it to Nexus
as classifier pc-stick. pc stays the ISO QEMU boots.
- scripts/nightly.sh gitea-release <tag>: the tag as a Gitea release -- a
pre-release for -alpha.N and the like -- notes from the tag's message with
the checksums, the images, SHA256SUMS, the documents and the StarshipOS
Root CA's certificate attached; run again, it adds only what is missing.
release.yml runs it after the Nexus publish, with the secret RELEASE_TOKEN.
Tested here: images builds pc-stick.img.xz (785 KB); gitea-release against
a stand-in Gitea API made a pre-release with the notes and ten files, and a
second run added nothing.

Since #151 an idle guest halts (1% of a core at the prompt), so the cap no
longer has to hold back spinning sessions. Captain Bob set 1.5 cores for
all sessions together on the server (2026-11-08): one busy visitor a full
core, half a core always left to the wikis and Gitea. Confirmed on the
server with a live session idle for 3 minutes.

An idle StarshipOS kept a CPU core 100% busy: sk_v4_readline(), with
nothing typed, and sk_v4_identity_wait(), headless until Zuse, waited in
arch_relax(). Both now halt until the next interrupt (hlt; wfi on aarch64
and riscv64): the heartbeat's timer, ISR-driven on all three, wakes them at
100 Hz, so a key is still seen within a tick.
Idle at the prompt, QEMU's CPU: 100% -> 1% of a core on amd64, 1% on
aarch64 and riscv64. Acceptance passes: amd64 logs/20261108-005539, aarch64
-005753, riscv64 -010136 (POST 538/538, one dict_hash, 7 ok), the stick
loaded high, test-32 (39 programs, 0 failures). FABRIC-3 XLVIII.5.

The canvas's Home and Inquiries artboards gain a 'Try it' link (canvas
versions 12, 13); canvas/ copies them, build.py rebuilds the pages, and
install.sh put them on the wiki. Checked as a visitor: the home page, the
link, the Try it page in 1.1 s, its framed console Ready. FABRIC-3 XLVIII.4.

An idle StarshipOS guest keeps a host core 100% busy (measured 2026-11-08:
QEMU at 100% of a core, 148 MiB, the guest idle at its prompt; #151).
starshipos-demo.service: CPUQuota=100% and Nice=19 for all sessions
together, MemoryMax=1G -- sized for this server, where the old 300% and 4G
let two visitors starve both wikis and Gitea. DEPLOY.md says how to apply
it. FABRIC-3 XLVIII.4: Try it deployed and checked from outside; the ttyd
package's own login service; #151, #152.

Ubuntu's ttyd package starts ttyd.service, which runs login on port 7681;
installed by step 1, it took the port, and try.starshipos-f18.com served
the server's login prompt until it was disabled (2026-11-08). Step 4 now
disables it first and checks what listens on 7681. And the check from
outside, done: ready in 1.5 s, 7 ok, 49 ok, the third visitor busy.

Five steps on the server after #148: the checkout and amd64 build tools,
the demo's own Zuse, the image and the saved machine at 384 MiB, the
service, TLS and Apache for try.starshipos-f18.com; then the check from
outside and the .com's navigation link (#115, #116, #117).

Today's rulings and work since XLVII.6, kept at the pace of the work
(Captain Bob, 2026-11-07: 'the book of fabric needs to keep pace'): the
alpha.4 list (#147) and what is in it, the developer protocol (#135), the
Book of Fabric (#138), the SDK milestone with the capsule repository (#149)
and the latency DoE (#150), #136 and the demo's guests and busy message,
with what was measured.

Captain Bob, 2026-11-07: 'Limit guests and have a Busy, try back in a few
minutes.' start-session.sh takes one of DEMO_MAX_GUESTS slots (default 2),
a lock it holds for the session's life (flock -n: two visitors cannot both
take the last one; QEMU and the bridge are started without its descriptor);
with every slot taken, the visitor's terminal says every machine is busy and
to try back in a few minutes, and the session ends without a machine. The
service: DEMO_MAX_GUESTS=2, RuntimeDirectory for the locks, ttyd's
--max-clients 6 so a visitor over the limit reaches the message. The guest:
384 MiB (v4 boots from 256 MiB, refuses at 128; measured, #116). Tested
here: every slot held -> the busy message; slot 1 held -> slot 2 taken.

Run 197's riscv64 failure (#131) could only be read from the run's logs
artifact, which Gitea's API does not list. qemu_session.py's check() now
prints, on a FAIL, the serial lines after the first match of an anchor the
check names, or the log's last lines; control characters as escapes, so a
stray byte or terminal sequence in a line shows instead of only failing a
match. The boot-disk checks anchor on 'Boot successful!'. A passing run
prints as before (riscv64 here, logs/ committed).
