The variable name 'format' shadows the method parameter name used in the switch expression. Consider renaming to 'reportFormat' for clarity.

            ReportFormat format = settings.OutputFormat.ToLowerInvariant() switch

+
+            var report = reportGenerator.GenerateReport(comparisonResult, format);
+
+            // Output report


[nitpick] The comment 'Output report' is not descriptive. Consider expanding it to explain that this outputs the formatted report to the console using AnsiConsole.

Suggested change

// Output report

// Output the formatted report to the console using the AnsiConsole library

+            Assert.Equal(0, result);
+            mockAssemblyLoader.Verify(al => al.LoadAssembly(sourceAssemblyPath), Times.Once);
+            mockAssemblyLoader.Verify(al => al.LoadAssembly(targetAssemblyPath), Times.Once);
+            mockApiExtractor.Verify(ae => ae.ExtractApiMembers(It.IsAny<System.Reflection.Assembly>()), Times.Exactly(2));


The magic number '2' should be replaced with a named constant or comment explaining why ExtractApiMembers is called exactly twice (once for source, once for target).

Suggested change

mockApiExtractor.Verify(ae => ae.ExtractApiMembers(It.IsAny<System.Reflection.Assembly>()), Times.Exactly(2));

const int EXPECTED_API_EXTRACTION_CALLS = 2; // Number of assemblies processed: source and target

mockApiExtractor.Verify(ae => ae.ExtractApiMembers(It.IsAny<System.Reflection.Assembly>()), Times.Exactly(EXPECTED_API_EXTRACTION_CALLS));

- SA1515: Added blank lines before single-line comments - SA1011: Added spaces after closing square brackets - SA1206: Reordered modifiers to put 'required' before 'public'

- Improved comment for output report to be more descriptive - Added named constant for API extraction calls in tests

I've addressed the code review comments:

Improved the comment for the output report to be more descriptive
Added a named constant with a comment to explain the magic number '2' in the test file

Note that the configuration loading logic will be implemented in a subsequent task as mentioned by @jbrinkman.

I've improved this comment to be more descriptive about what's happening here.

Added a named constant with a comment to explain why we're verifying that ExtractApiMembers is called exactly twice.
