ran in parallel

The database optimizer chose a sub‑optimal query plan for the /internal/reports/monthly-summary endpoint, likely due to stale statistics or missing index, resulting in higher latency.

Remediate Agent

grounded by runbook match, pre-gate

Proposed action: no_action_needed

The issue is a minor query‑plan regression on a low‑traffic internal endpoint (P4). The runbook for “Slow query plan regression” explicitly recommends no_action_needed for regressions below P3. Since the diagnosis and severity align with the runbook guidance, no remediation action is required; the incident will be flagged for the reporting‑db‑team’s routine review.
