- Preserve HDF5 as authoritative FESA output.
- Use the B33 mixed tolerance exactly for MITC4 U; U blocks and UR warns only.
- Use fixed absolute `1.0e-5` for MITC4 U/UR; U blocks and UR warns only. Keep the
separate B33 mixed tolerance unchanged.
- Retain fixed numerical drilling stabilization but exclude calibration and drilling evidence outputs.

The fixed value is expressed in the model's user-consistent length unit for translation

diagnostic report data but does not enter the tolerance or normalized-error denominator.

No additional locking, convergence, distorted, curved, director-angle, or invalid
geometry reference portfolio is required for this MITC4 implementation acceptance.
