The fleet's 22:09 UK incident (a Mac-side pkill -f <log file name> matched nothing, the roll-everything script lived on and wiped a held box) and the day's two pgrep self-matches are one class. The check flags pgrep -f / pkill -f with a plain literal (every one on a line), any pgrep/pkill on a file-name shape, and ps | grep with a literal; it allows the bracket form, -x, -F pidfile, kill $(cat pidfile), a variable and a full path; 11 banned and 16 allowed shapes in its self-test; 0.15 s over the tree. The 25 pkill -f sp1-gpu-server inside bash -c bodies (which matched the calling bash) are pkill -x; the other 11 literals take the bracket form; prover-socket-check accepts both. Row R in the record; the CLAUDE.md rule names the check and covers pkill and file names.

the project lead's decision of 6 October 2026: the Mac runs nothing the network depends on. docs/plans/hands-on-build-1.md plans node 1
and the observer (its node and tools/observer) as systemd units on the box, one hand at a time, with ports, DNS names,
exec recovery, rollback and the decisions for main; infra/build-server/hands/install-hands.sh writes users, dirs, run
scripts and units (inert, run on the box); move-hand.sh (dry run by default) builds 0.3.15 on the box, copies the override
and snapshot, rsyncs each data dir hot then stopped, starts the unit and prints the hand's first executing line, copies the
observer env by scp (mode 600), stops the Mac's observer first, unloads the launchd agents last. CLAUDE.md's running-agents
rule carries the decision. lib.sh: a per-worktree lock on the box across sync, build and fetch (the shipper's collision at
18:48:56Z). remote-run.sh: the clean-tree test excuses stamps and target dirs at any depth with --untracked-files=all (a
nested stamp failed every checkout of /srv/builds/igneum for twenty minutes) and removes a stale .git/index.lock; the
self-test covers both. Plan rows for the three and the cuda prover pair built for the shipper.
