Rulename	Google SecOps - Single-Event Alert
Description	Creates incidents in Microsoft Sentinel when Google Security Operations raises an active single-event alert (SINGLE_EVENT, riskScore gte 40) at MEDIUM, HIGH, or CRITICAL severity. These alerts represent a single action like malware execution, credential abuse, or defense evasion severe enough to trigger an incident without requiring multi-signal correlation.
