- Add mergerfs_mount() context manager in posix_parity.py that creates temporary branch dirs in tests/.test_tmp/, mounts an ephemeral mergerfs instance, and cleans up after use. - Add find_mergerfs(), find_fusermount(), mount_mergerfs(), unmount_mergerfs() helpers. - Update run-tests to invoke each TEST_* script without a mountpoint arg. - Update README.md to document the new `python3 tests/run-tests` invocation. - Fix 44 tests to use mergerfs_mount() instead of expecting a pre-mounted path. - Add tempfile import to 10 tests that were missing it. - Fix TEST_mount_lifecycle to use mergerfs_mount() context manager. - Fix TEST_posix_tmpfile missing join import. - Fix TEST_cfg_xattr_modes error message framing (no "(known bug)"). - Fix TEST_posix_copy_file_range: loop-copy full size, compare st_size and SHA256 hash; add NativeTmp for space management; route native temp to tests/.test_tmp/ to avoid ENOSPC on /tmp. - Fix TEST_posix_getattr_fgetattr: st_cmp skips st_size for dirs; add compare_ino param for safe inode comparison when inodecalc=passthrough. - Fix TEST_unlink_rename, TEST_use_* tests: namespace cleanup, consistent variable naming, None check for cmpfunc. - Fix TEST_readlink_semantics: remove type annotations to support older Python; wrap in mergerfs_mount() try/except. - Add flush=True to run-tests print so test names show immediately.
