Review Comment:
   Just curious, is the use of `Map<SensitivePropertyAttribute, String>` 
intended to limit the context to framework-defined attributes? Future providers 
might need additional context (cluster, tenant, data domain, key alias for key 
selection, or external audit records). Would `Map<String, String>` with 
constants for NiFi defined keys provide that extension point while preserving 
standard names? Something like
   
   ```java
   public record SensitivePropertyContext(
           SensitivePropertyCategory category,
           Map<SensitivePropertyAttribute, String> attributes,
           Map<String, String> additionalAttributes
   ) {
   }
   ```
