- run-tests.sh: no systemctl start/stop, just runs test-unit.py - synth-diagnostic.service: removed Before=, keeps After=prometheus-exporter (no deadlock risk since run-tests.sh doesn't start services) - justfile deploy: stop pipeline -> restart prometheus -> start synth-diagnostic -> restart pipeline Pipeline starts independently at boot (no After=synth-diagnostic). Diagnostic provides visibility at boot without blocking startup.
