// TestUnicornFilenameCaseDirectoryHandling verifies directory checking order,
// the `$` directory exemption, `checkDirectories: false`, and the
// path-boundary rules for nested files inside and outside the project directory.
//
// The native rule reports the first offending directory before checking the
// basename, skips `$`-prefixed directory segments, and checks outside-project
// files by basename alone. The outside `Src` segment must not be reported.
//
//  1. Lint layouts with bad directories, `$` directories, and disabled
//     directory checking.
//  2. Lint project-rooted and outside-project absolute paths.
//  3. Assert the independent literal diagnostic or silence for each.
//
// @evidence contracts/testing.md#behavioral-verification The rule resolves virtual in-project and outside-project paths and checks configured directory handling against exact messages.
// @evidence contracts/testing.md#independent-expectations The supported checkDirectories scope and authored path/case alternatives establish report ordering and outside-project exclusions independently.
// @evidence contracts/testing.md#distinguishing-cases Retained root, nested-directory and outside-project paths cover both checked and exempt segments.
// @evidence contracts/testing.md#execution-ownership TestUnicornFilenameCaseDirectoryHandling owns its retained literal paths/options as a discoverable Go unit entry; engine/configuration operations run in the shared process using virtual or isolated fixture paths, without installing a consumer, native build or product host.
