fix: recognise grafana_alert_rules in check_evidence_availability (#684)

kaushal-bakrania · kaushal-bakrania · commit 726ce264f54a · 2026-04-19T23:36:26.000+01:00
The key is already in _INVESTIGATED_EVIDENCE_KEYS and emitted by the _map_grafana_alert_rules mapper, but check_evidence_availability's has_cloudwatch_evidence OR-chain never probed it. A healthy alert whose only evidence was grafana_alert_rules fell through to _handle_insufficient_evidence instead of satisfying the evidence gate. Same drift-bug class as commit 3dbfb52 (EKS) and open PR #672 (AM/CL/HC).
