Research direction
Load sdk.slnx and locate the Microsoft.CodeAnalysis.NetAnalyzers.UnitTests tests, especially RecommendCaseInsensitiveStringComparison_CSharp_Tests.Diagnostic_Assign. Inspect the parameterized cases behind the duplicate IDs, then run the affected unit tests and confirm that no duplicate-test-case warnings remain.
