Self-hosted, no paid SaaS. Host/container/Postgres metrics, uptime probes against the new /healthz endpoints, alert rules split critical (pages) vs warning (informational), one starter Grafana dashboard. Deliberately separate from the application's instructor learning analytics (Phase 3B) - different audience, different data. Validated: promtool check config (valid), promtool check rules (11 rules, valid), amtool check-config (1 inhibit rule, 2 receivers, valid).
