On Windows, LockFileEx prevents renaming to a locked file. Move atomic_replace calls outside lock contexts in clear() and compact() methods. Simplify file creation cases since atomic_replace handles races via temp file pattern.
Windows doesn't support opening directories with os.open(). Skip the directory fsync step on Windows since NTFS handles atomic renames differently. Also fix test_repr to use path.name to avoid Windows path separator differences in assertions.
Same fix as table repr test - use path.name to avoid Windows path separator differences between str(path) and repr(path).
The greenlet dependency can't be built on Windows with free-threaded Python 3.14t. Mutation testing with cosmic-ray is only run on Linux anyway.
Regenerate lockfile after adding sys_platform != 'win32' constraint to cosmic-ray. This removes Windows-specific wheels for cosmic-ray's transitive dependencies.
Refactor Table class to use FileSystem protocol for better testability: - Add _filesystem.py with FileSystem protocol and RealFileSystem implementation - Inject FileSystem dependency into Table via _fs parameter - Create FakeFileSystem test double for edge case testing Add comprehensive tests for previously uncovered code paths: - Surrogate pair validation in encoding - append_lines function in writer module - Header serialization edge cases - Transaction repr and edge cases - Table filesystem error handling paths Mark legitimately untestable code with pragma comments: - Protocol method stubs (abstract definitions) - Defensive unreachable code paths - Windows-specific lock implementation
