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).
