#!/usr/bin/env bash
# Start one adv-cache-3 sweep on a build box (run ON the box). Internal adversarial pass, not an independent review.
# run-box.sh <tag> <args...>
# The binary is /srv/builds/_adv-cache-3/bin/adv-cache-3 (copied there after tools/build-remote.sh; the worktree mirror's
# target dir is not used at run time). The log and pid file live under /srv/builds/_adv-cache-3/logs/<tag>.log{,.pid},
# outside the worktree mirror, which build-remote.sh's source sync would wipe. The run takes the per-box sweep lock
# (/srv/builds/_adv/locks/sweep.lock, coordinator's rule of 19:55 BST, 7 October 2026: one sweep per box at a time, up to 88
# threads), runs at nice 10 on cores 8 to 95 (0 to 7 reserved), no SIGSTOP yield. Kill by pid file only: kill $(cat <pid>).
# run-box.sh <tag> <args...> (THREADS=N caps the pool ask; default 32, the ceiling an adv holder keeps)
# The binary is /srv/builds/_adv-cache-3/bin/adv-cache-3 (copied there after tools/build-remote.sh). The log and pid file
# live under /srv/builds/_adv-cache-3/logs/<tag>.log{,.pid}, outside the worktree mirror, which build-remote.sh's source
# sync would wipe. Every sweep starts through the build-server lane's ranked lease (main, 7 October 2026, 20:1x and 20:40
# BST: `lease pool`, class adv, holders above 32 threads are pre-empted), pinned by the lease to the cores it took, at
# nice 10, never on cores 0 to 7; "{cores}" in the arguments becomes the count taken. No `-c` string, no inline rm
# (main, 21:33 BST). Kill by pid file only: kill $(cat <pid>).
