sshd, pam_unix, sudo, CRON, systemd, kernel, rsyslogd, and dbus-daemon
all share the SSH/telnet decky containers and write to the same syslog
socket as DECNET's own emitters. Their output was being parsed and
ingested into the JSON stream, the dashboard, and the profiler — pure
noise: sshd's "Failed password for root from X" duplicates the
auth-helper's structured auth_attempt event, pam_unix repeats it again,
CRON/systemd say nothing about attacker behavior.
Drop these APP-NAMEs in _should_ingest before the JSON write and bus
publish. Raw .log file still captures everything for forensics. The
denylist is overridable with DECNET_COLLECTOR_DROP_APPS so operators
can extend it without code changes.
