Northstar carried working northstar.dns.* instruments but shipped no telemetry, so its dashboard was empty and the only northstar data in Elasticsearch was journald scraped under the systemd unit name. Two gaps, both outside the instrumentation. northstarStartCmd never called initTelemetry, unlike every other service command, so the instruments recorded into a no-op provider. The unit also did not source /etc/spinifex/telemetry.env, which every other application unit reads for OTEL_EXPORTER_OTLP_ENDPOINT, MULGA_ENV and MULGA_SOURCE — so even an initialised SDK would have had no endpoint and no env label. Add an invariant covering the second gap: any unit launching an spx service must source the telemetry drop-in. A service missing it starts healthy and silently reports nothing, which only surfaces when someone notices an empty dashboard. Verified the test fails against the unpatched unit.
