Rename the container-side logging module decnet_logging → syslog_bridge (canonical at templates/syslog_bridge.py, synced into each template by the deployer). Drop the stale per-template copies; setuptools find was picking them up anyway. Swap useradd/USER/chown "decnet" for "logrelay" so no obvious token appears in the rendered container image. Apply the same cloaking pattern to the telnet template that SSH got: syslog pipe moves to /run/systemd/journal/syslog-relay and the relay is cat'd via exec -a "systemd-journal-fwd". rsyslog.d conf rename 99-decnet.conf → 50-journal-forward.conf. SSH capture script: /var/decnet/captured → /var/lib/systemd/coredump (real systemd path), logger tag decnet-capture → systemd-journal. Compose volume updated to match the new in-container quarantine path. SD element ID shifts decnet@55555 → relay@55555; synced across collector, parser, sniffer, prober, formatter, tests, and docs so the host-side pipeline still matches what containers emit.
