- fs-tree joins listed paths with the platform separator (Windows rows previously leaked mixed separators) - media route containment check goes through isWithin(): separator- tolerant and case-insensitive on win32, so case-mismatched Windows paths are not misclassified - relativeTo compares case-insensitively (Windows / case-insensitive macOS volumes) while keeping the caller's own casing in the output - tests: platform-conditional path assertions, os.tmpdir() instead of /tmp, isWithin/relativeTo/resolveSidebarPath win32 coverage
