`docker rm -f` returns once removal is INITIATED, not once complete. The
bench container holds ~92 GB of GPU memory plus the offloaded PLE mapping, so
the name stays reserved for several seconds while the device is released. The
next `docker run --name` then dies with a name Conflict.
That failure was near-invisible: run_arm treats a failed boot as
`arm SKIPPED`, the campaign continues, and it still prints CAMPAIGN DONE.
Observed 2026-09-13 -- arm k1 lost the race after off_A's loaded container,
while k2 won it only because k1 had never started a container to tear down.
Every arm that follows one which actually ran is exposed, so k3 and off_B were
both on track to vanish from a run that would have reported success.
stop_bench now polls until the name is released (120s ceiling, warns and
continues). Added a completeness gate: the campaign asserts every expected
res-<arm>-rep<n>.json exists and reports CAMPAIGN INCOMPLETE naming each
missing result rather than DONE, so a gutted run cannot look like a clean one.
Verified the docker ps format string empirically -- an earlier draft nested
quotes so the template rendered as '{{.Names}}' with literal quotes, which
grep -qx could never match, making the wait a no-op that passed bash -n.
