infra/build-server/capacity: igneum-capacity.service (user build, Nice 19, SCHED_IDLE,
CPUQuota leaving 8 threads free) runs run.sh, a controller over a priority queue of jobs
that pauses (SIGSTOP) the instant a build slot or the measure hold is taken (5 s poll of
/srv/builds/_locks) and resumes after. Jobs, each with a dry-run and a 10-min smoke:
pow fuzz (continuous, seed base advances), sync-request fuzz against a throwaway pruned
node on loopback (the Horizon 28-unwrap gate, igneum-p2p-probe sync-fuzz), GHOSTDAG and
finality sweeps seeds 1 to 1,000, model.py sweeps cached, clippy+audit per recent branch.
Summaries to /srv/workers/capacity.json; the worker dashboard gains a Background lane
(collect.mjs doc.background, page renderBackground). Night battery stops and restarts the
layer. docs/plans/build-server.md section 8. igneum-pow fuzz tests and ghostdag_sim.py /
attacks.py gain a seed-base knob for the continuous sweeps.

tools/workers/collect.mjs runs every 30 s on the box (infra/build-server/workers/igneum-workers.{service,timer},
install.sh) and writes /srv/workers/workers.json from the machine itself: /proc/stat deltas per core, meminfo, df on
/srv, net bytes, hwmon temperatures, the flock state of /srv/builds/_locks, cargo processes with worktree, target and
start time, flock waiters, /srv/builds/_log/builds.jsonl (the format agreed with the build-server agent), sccache
--show-stats, headline.json. tools/workers/push.mjs (launchd every 60 s) adds the Mac's with-lock slots and waiters
and the two PCs' relay job states from the intake, drops them on the box so its file is whole, merges the box's file
and writes the fleet folder's workers.json; it deploys only when the live copy is over 6 min old, otherwise the
fleet orchestrator's 5-minute deploy carries it. The page (tools/workers/page/workers.html, shape.js) tries
https://build.igneum.network/workers.json first and falls back to the folder copy; core strip, arcs, now building,
queue, recently done with closing lines, headline timings, analytics; UK time with UTC tooltips; phone width.
node --test tools/workers/test: 13 tests over /proc/stat, lock dir, JSONL and sccache fixtures and the page shaping.
