WHY IT NEEDS A POLICY

Why CreateAHOSequenceStore needs a policy

The tool creates a new AHO Sequence Store, which is a persistent data resource. This is a Write operation as it creates/provisions new infrastructure or data storage. Severity is high because creating sequence stores in AWS IoT SiteWise could affect data management pipelines and incur costs, though it is reversible (unlike Destructive operations).

From the tool's definition Tool name 'CreateAHOSequenceStore' indicates creation of a resource (sequencing data store). The 'Create' verb signals a Write operation. Tool description is empty, limiting direct evidence from documentation.
