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.
