- run_case: --diagnostic scaled_shear_n256 (requires --flow shear_wave;
U256/U512/constant R256/projected R256, Re100, no early trace); N512
only via one of the two scaled diagnostics; scaled_n256 stays TG-only.
- assess_shear_wave: scaled=True contract reusing 92b8afe scaled
case/build/workload checks, shear diagnostic identity; signed rate bias,
refined excess over each control; hash-pinned de5b0cc N128 reference and
descriptive N128->N256 signed trend; CLI --diagnostic/--reference-files.
- tests: scaled contract, set mixing, trend/reference pin, runner options.
- shear_wave.py and oracle.py unchanged.
