### 17.5 Reference-comparison boundary
Abaqus comparison uses only the declared full-integration S4 case and blocks only
on matched global `U1/U2/U3` rows under
`tolerance_c=1e-9+1e-6*reference_scale_c`, where `reference_scale_c` is the maximum
absolute finite Abaqus value for the same component. `UR1/UR2/UR3` uses the same
formula but an exceedance emits only a deterministic nonblocking warning.
on matched global `U1/U2/U3` rows under the fixed absolute criterion
`abs(fesa-reference) <= 1.0e-5`. `UR1/UR2/UR3` uses the same fixed absolute value but
an exceedance emits only a deterministic nonblocking warning. A reported reference
scale is diagnostic only and does not enter the MITC4 decision or normalization.
FESA `S4` and `S4R` inputs must produce the same internal numerical rows for identical
supported models while preserving distinct source metadata. This common-path property
is verified without consuming an S4R Abaqus artifact; Abaqus S4R is not an acceptance
