- StorageServiceTests: replace out-param + manual dispose with IAsyncLifetime - PictureServiceTests: Assert.True bound checks -> Assert.InRange - CreateAlbumCommandHandlerTests: assert the specific NotFound error type instead of just IsError, matching what the test name promises - CreateAlbumRequestValidatorTests: replace a boundary Theory that computed its expected result inline with explicit Facts against the real AlbumReleaseYear constants - Remove unused using directives across a handful of production and test files found during the review Full suite verified green: 250/250 tests passing, 0 build warnings.
