Three root causes confirmed via live server investigation (issue #604): 1. ManagementWebSecurityAutoConfiguration applied HTTP Basic auth to the management port (8081), causing Prometheus to receive 401 HTML responses instead of metrics. Excluded the auto-config — the Docker network (archiv-net) provides the security boundary for this internal port. 2. promtail-config.yml had no `job` relabel rule. Grafana's Loki dashboards query {job="$app"} which matched nothing; logs were in Loki under compose_service but invisible to every dashboard panel. 3. prometheus.yml had a stale comment claiming the spring-boot target would be DOWN until micrometer-registry-prometheus was added — it has been present in pom.xml for some time.
