01 / THE QUESTION

Editorial guide

Which internal operators of a layered linear mechanism are fixed by input/output behaviour, and what does adding one internal measurement port fix?

02 / WHAT THE RECORD SAYS

Source passage

Thus a single internal measurement port plus spanning experiments makes both operators individually identifiable in the port's chosen coordinate system.

03 / LIMITS & OPEN POINTS

Source passage

Values outside the reachable subspace are not determined by the experiment.

04 / THE NEXT QUESTION

Editorial guide

How should an automated scientist choose the cheapest sequence of experiments that removes the remaining gauge ambiguity?

05 / CHECKS IN THE RECORD

Editorial guide

This record does not separate a verification section. Read its methods, assumptions and original source before treating a claim as checked.
