# OB-1b: sample who is holding the house runlock, once a minute.
#
# Three sibling workflows (OB-2, OB-3, OB-4) share this box's runlock with this
# leg, and the receipt should be able to say how the night was actually shared
# rather than guessing. One `ps` per minute is far below any thread wall and
# touches nothing. Columns: UTC, lock present, and the worktree path of whatever
# llama-perplexity is executing, which identifies the leg holding it.
