# Description Improve Reference Server coverage for OPC UA Compliance Test Tool scenarios and document the latest CTT findings. ## Reference Server coverage - Historize the configured AccessRights nodes and seed them with the same deterministic mixed-quality history as the other test nodes while preserving their access controls. - Add a historian node that intentionally does not support ServerTimestamp. - Add a SelectionListType String instance whose Selections property is String[] as required by Part 5, with localized descriptions and RestrictToList enforcement. - Add an EUR CurrencyUnit property and verify its structured value and binary encoding. - Add a node with explicit read/write base access bits plus NonatomicRead and NonatomicWrite AccessLevelEx flags. - Ensure the first ByteString array elements meet the CTT minimum-length prerequisite. ## Latest CTT findings - Confirm run-23 A&C residuals are CTT re-entrant Read and branch-unaware Retain checks rather than server regressions. - Confirm NumberOfTransitions includes Uncertain values as required by Part 13. - Document the CTT CurrencyUnit decoder dropping a correctly encoded Exponent. ## Related Issues - Follow-up to #3960 and #4002. ## Checklist - [x] I have signed the [CLA](https://opcfoundation.org/license/cla/ContributorLicenseAgreementv1.0.pdf) and read the [CONTRIBUTING](https://github.com/OPCFoundation/UA-.NETStandard/blob/master/CONTRIBUTING.md) doc. - [x] I have added tests that prove my fix is effective or that my feature works and increased code coverage. - [x] I have added all necessary documentation. - [x] I have verified that my changes do not introduce (new) build or analyzer warnings. - [ ] I ran **all** tests locally using the **UA.slnx** solution against at least .net **framework** and .net **10**, and all passed. - [ ] I fixed **all** failing and flaky tests in the CI pipelines and **all** CodeQL warnings. - [x] I have addressed **all** PR feedback received. Focused affected tests pass on .NET 10 and .NET Framework 4.8. --------- Co-authored-by: copilot-swe-agent[bot] <198982749+Copilot@users.noreply.github.com> Co-authored-by: Marc Schier <marcschier@hotmail.com>
