B.5.RR:10 - Architectural Rationale

An argument and an application can change separately. A theorem can remain established while its former substitution ceases to answer the question. An empirical premise can become doubtful while its conditional consequences remain worth investigating. Keeping those distinctions lets revision preserve knowledge without preserving an unsupported use.

The method therefore joins backward recovery of what the desired result needs with forward derivation from the premises now available. Alternative arguments preserve useful results; shared prerequisites explain where that preservation fails. Detailed deduction, statistical inference and physical-model revision remain contributions of their respective practices.

This is a method of obtaining and applying knowledge. Its result can also change the method repertoire: the revised sum reveals a parameterized construction, and an unresolved dependency can become the next research question. Those continuations are useful when they enable further work.
