PHY.4:4.5 - Obtain the needed consequence and choose the next use

Use the constraint for the original question. It may reject an impossible response direction, locate a missing input, restrict a learned or symbolic model, bound a consequence, or identify a condition under which competing laws disagree.

MMP.11 supplies a mathematical family respecting the physical constraints. When a quantitative value is needed, an interaction theory, interpreted observations or another appropriate method can constrain its remaining freedom. C.16.IR handles inference from interpreted indications; MMP.7 formulates a probability law for recorded data when the inference uses that form. C.29.2 supplies a computational formulation.

Choose further work from the unresolved consequence. A direction or family-wide bound may already suffice. If a missing magnitude changes the decision, obtain the needed contribution at a useful range and precision. A proposed experiment or simulation should discriminate something that matters to that next move.

When a changed situation gives a response outside the family, inspect the physical comparison before adding arbitrary terms. A preferred direction, external drive, stored state or different regime can change the family itself. Retain earlier consequences where their premises still hold.
