It is the same discipline that already governs any energy-conversion bookkeeping in general relativity — the reason, for instance, that a photon climbing out of a well arrives redshifted by exactly the factor it was blueshifted falling in, with no leftover to spend — applied here to a resource, orthogonalization count, that is not itself an energy but is built multiplicatively from one. The identity is a consistency check on the definition of [] , confirming the object was built correctly, not a physical discovery in its own right. The physical content of this article is entirely in the…
