Class-invariant information and reference rebasing

Thus changing a reference quartic by an allowed local contact changes the written representative, but does not automatically create a different quotient-membership problem. In particular, such a change is not correctly described as “never a contact correction.”

A changed gauge rule, switching prescription, admissible domain, or reference modification outside the declared class changes the evaluation contract and requires a new comparison. Identical numerical values are then neither automatic nor sufficient to identify the problems.

The class-invariant principle resembles the role of preserved data in the supplied XI-G source record CheungXI. That manuscript's obstruction is not imported as a contact separator.
