Notes

• Versioning: Every PutParameter (including overwrites) creates a new version. GetParameterHistory returns all versions.
• SecureString: When WithDecryption: false, the value is replaced with a masked placeholder. When WithDecryption: true, the plaintext is returned (no real KMS encryption).
• Path hierarchy: GetParametersByPath with Recursive: false returns only direct children of the given path. With Recursive: true, all descendants are returned.
• Pagination: GetParametersByPath and DescribeParameters support MaxResults + NextToken pagination.
• Protocol: Uses AWS JSON 1.1 (X-Amz-Target: AmazonSSM.*, application/x-amz-json-1.1) and Smithy RPC v2 CBOR.
