PR #6 described adding a unit test class for deterministic identifiers, but no such class existed in WebExpress.WebUI.Test. The three Copilot review comments marked outdated were already resolved in prior commits; the fourth (null handling in UnitTestControlListItemButton) was already correctly implemented via the ternary guard.

Changes

• New: src/WebExpress.WebUI.Test/WebHtml/UnitTestDeterministicId.cs — adds a dedicated test class for DeterministicId.Create() under a new WebHtml/ folder, covering:
  • Same callsite → different IDs (call stack context differs by IL offset)
  • Different context values → different IDs
  • Different callsites (distinct lambdas) → different IDs

[Fact]
public void CreateDifferentCallsites()
{
    var callsiteA = new Func<string>(() => DeterministicId.Create());
    var callsiteB = new Func<string>(() => DeterministicId.Create());

    Assert.NotEqual(callsiteA(), callsiteB());
}

The structure and naming mirrors the equivalent test class in WebExpress.WebCore.Test.
