obs-pipeline

What ships telemetry where — instrument a service with OTel and route metrics, traces, and structured logs through Alloy/collectors to Loki, Mimir, and Tempo. Triggers: 'instrument this service', 'add telemetry', 'logs are not reaching Loki', 'configure the Alloy exporter'. Not for reading signals (obs-logs, obs-metrics, obs-traces) or Grafana datasource/dashboard configuration (grafana).
