For every matched U/UR row:

The `1e-9` absolute floor is expressed in the model's user-consistent length unit for
translation and as a dimensionless rotation value for warning-only UR. Values are not
zero-clamped. Missing, duplicate, unmatched, or nonfinite required rows fail before
numeric tolerance evaluation. U tolerance failure fails reference verification; UR
tolerance exceedance emits a deterministic warning only.
The fixed value is expressed in the model's user-consistent length unit for translation
and as a dimensionless rotation value for warning-only UR. Reference scale may remain
diagnostic report data but does not enter the tolerance or normalized-error denominator.
Values are not zero-clamped. Missing, duplicate, unmatched, or nonfinite required rows
fail before numeric tolerance evaluation. U tolerance failure fails reference
verification; UR tolerance exceedance emits a deterministic warning only. The B33 mixed
tolerance remains unchanged.
No additional locking, convergence, distorted, curved, director-angle, or invalid
geometry reference portfolio is required for this MITC4 implementation acceptance.
