PHY.4:9 - Consequences
Useful physical restrictions become available before a complete mechanism or fitted law is known. They can guide formulation, reject an incompatible model or direct a discriminating inquiry. The remaining freedom also becomes a specific task rather than an implicit assumption.
The result is conditional on the physical comparison. An added direction, stored state or changed regime can reopen the law family. This makes the dependence of the conclusion inspectable and supports retaining the portions that still apply.
