igneum-labs 6f5787ed71 Build boxes: the measure file is retired; a pinned measurement leases its cores only (lease.sh cores), a whole-box quiet measurement is its own class (refused beside a slot or a lease, 20-minute cap, named owner), bounded suites never take it, every run keeps off leased cores, stopped holders are reaped after 5 minutes by every keeper, every waiter has a label file; the box-side self-tests in the gate; provision installs the lease tool and the headless Chromium libraries ... Main, 7 October 2026, 15:07 UK: one global exclusive measure flock across unrelated measurements stalled build-1 at load 120 with free slots (a stopped probe held it 5.5 h; an exclusive waiter queued every new shared taker) and build-2 behind a one-core VDF bench. lease.sh (installed at /srv/builds/_bin/lease by provision.sh and by hand on both boxes) takes one flock per core for a pinned measurement and the quiet file for a whole-box one; remote-run.sh takes quiet shared only for unbounded runs, excludes leased cores from its set, and its keeper refreshes the holder file and calls lease reap (a STOPPED holder of a lease, quiet or a slot for 5 minutes is killed with a line in _log/reaped.log). Keepers close the lock descriptors they inherit (an orphaned sleep held a slot and the worktree lock 20 s past the release; the slot self-test had rotted on that since the worktree lock landed). tools/ci/box-locks-check.sh runs lease.sh --self-test and remote-run.sh --self-test-slots on build-1. provision.sh also carries the 16 libraries headless Chromium needs (installed by hand on both boxes at 14:5x UK) and a headless self-test step.
