PHY.3:10 - Architectural Rationale

The complete transformation is the shared object of the two comparison constructions. It makes hidden resources and restoration conditions available to reasoning, while leaving the internal mechanism open. Reference cancellation reduces a proposal to a constrained composite effect. Input comparison constrains what one operation can do across alternatives. These differences explain the choice in :4.3; neither construction is a compulsory stage of the other.

The physical premise gives the mathematical operation its bearing on a device. A conserved sum or preserved inner product can be studied mathematically without that interpretation. Conversely, knowing the name of a physical principle does not yet specify the permitted exchanges, preparation or input family. The method supplies this physical construction and uses the existing mathematical and common inquiry methods for their contributions.

An ideal reference helps bound real proposals when its admitted operations and the coverage relation are explicit. It serves a different purpose from a realistic simulation of one device. Both kinds of account can remain useful in the same inquiry: the bound directs construction, and the constructed mechanism reveals further practical restrictions. The explanation of a failed proposal can also generate the next problem by identifying a consequential change of premise.
