 ## [Unreleased]
 
+### Fixed
+
+- **Pattern-2 ECR Enhanced Scanning Support** - Added required IAM permissions (inspector2:ListCoverage, inspector2:ListFindings) to Pattern2DockerBuildRole to support AWS accounts with Amazon Inspector Enhanced Scanning enabled. Also added KMS permissions (kms:Decrypt, kms:CreateGrant) for customer-managed encryption keys. This resolves AccessDenied errors and CodeBuild timeouts when deploying Pattern-2 in accounts with enhanced scanning enabled.

 ## [0.4.1]
