UModel RCA

Investigate to a root cause over the UModel object graph. Use this as a method, not a script: let evidence decide the next query, keep competing hypotheses alive, and cite every conclusion with an object-graph, metric, or log source.

Load umodel-query first. It provides the read surfaces used here: .entity, .topo, .umodel, .entity_set | entity-call get_metrics, and .entity_set | entity-call get_logs.

Setup

Same CLI as umodel-query — load that skill and follow its Setup; the essentials:

1. Ensure umctl is on PATH — UModel's read CLI:

command -v umctl || go install github.com/alibaba/UnifiedModel/cmd/umctl@latest   # needs Go 1.22+
