Severity / Routing Agent
ran in parallelP4 / infrastructure
Routed to: infrastructure-platform-team
The reported degradation is a direct result of a scheduled node pool maintenance window. There is no customer-facing impact, and historical data indicates this is a known, expected behavior for these maintenance events, consistently classified as P4.
Self-reported confidence: 100% (audit-only — not used by the gate)

Scenario Matcher
deterministic, pre-LLMScheduled maintenance window overlap
Alerts overlapping a known maintenance window are expected noise; no automated remediation action is warranted.
Match score: 87% · Recommended action: no_action_needed
Matched tags: maintenance, scheduled, overlap
Remediate Agent
grounded by runbook match, pre-gateProposed action: no_action_needed
The alert was generated during a scheduled node‑pool maintenance window, which intentionally places the pool in a degraded state. No customer impact was observed and the runbook for overlapping maintenance recommends no remediation. Therefore, no action is needed.
