MATH.8:10 - Architectural Rationale
The method builds a solution family from an action and a preservation relation. Keeping data inside that relation distinguishes transformations of one fixed problem from transformations between problems of the same form.
Generating the orbit and classifying all solutions answer different questions. The finite-closure argument explains when generation is complete; a stabilizer explains repeated results; another representative or reduction accounts for a missing orbit. These operations keep useful mathematical content beyond the instruction to notice a symmetry.
MATH.7 constructs operations through an arbitrary bijection. Here the transformations act on a specified problem and preserve its solution relation. MATH.5 can construct the action from assigned generators, while MATH.2 controls additional operations on identified results. The same orbit can support different receiving questions without giving its quotient every operation of the original set.
A direct solution, an existing orbit classification or a supplied parameterization is preferable when it already supplies the requested result. The group construction earns its cost when related answers, reduced cases or the reach of a family matter.
