PLN ran the root install at 20:06. Verified rather than assumed: the
deployed /usr/local/sbin/perf-audio md5 matches the repo copy, the bug's
fingerprints (nohup pulsar, SCRIPT_DIR) are absent from the deployed
script, and prioritization is retained.

Behavioural confirmation is the part worth keeping: the Bridge's perf
watcher still reasserts every cycle, but now only prioritizes -- no
launch attempts in the journal -- and the last Pulsar SIGABRT in
coredumpctl is 15:58:44, before the deploy. The counter that ran 183 deep
since 2026-08-19 has stopped.
