- Failure modes include cases where the limit is discontinuous (e.g., entanglement has no classical counterpart), where the new theory predicts new phenomena in the old theory's regime that were overlooked, and where the "classical theory" is itself an effective approximation to something deeper.
This sourceEstablishes that quantum expectation values of position and momentum obey the classical (Hamilton) equations of motion; supports the Ehrenfest-theorem mechanism in the Structural Signature (D13-101).

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Not recorded. The single citation of this work carries no recorded support check.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
