## The issue
- D125282253 removed the `--covariance` and `--std-threshold` flags from `run_ba.py`, so `align` now takes `(path, rec_a, rec_b, rigid, px_threshold)`.
- `test_main_calls_align_with_args` (added in D125284298) still asserted the old 7-argument call `("/data", 2, 3, True, False, 0.016, 0.3)`.

## The fix
- Update the assertion to the current signature: `("/data", 2, 3, True, 0.016)`.
