AI Incident Copilot

Optional explanatory context based on the same persisted evidence. It cannot change incident state.

Optional · non-authoritative
FALLBACKdeterministic-fallback · deterministic-rca-v1
Deterministic OpenDQ analysis identifies distribution shift as the leading explanation with high confidence.

This explanation follows the persisted deterministic RCA result. The leading cause is distribution shift; the AI provider was not used or was unavailable.

Evidence highlights

drift-result:1634{"column": "relative_humidity_pct", "method": "PSI", "metric": 1.0360062284025047, "status": "DRIFT", "threshold": 0.2}

Suggested investigation

  1. Compare the current distribution with the stored baseline and inspect the affected column.
