PHY.3:4.5 - Change the proposal at the premise that controls the result

Return the physical consequence in the terms of the working question. For a proposal outside the bound, identify a consequential change: supply a previously forbidden resource, allow a side effect, narrow the input family, relax precision or reliability, or change the condition for reuse. Derive the affected comparison again for the chosen change. Keep the original result for its original premises.

When the obstruction disappears, continue with a mechanism, an approximation or another limiting principle. PHY.2 can help construct a physical analogue for that inquiry; PHY.1 supplies physical similarity if transferring between regimes is the next difficulty. If the new question concerns an unfamiliar mathematical construction, obtain that contribution from Mathematical Thinking. B.5.MPC helps divide and reconnect those contributions across people and AI agents.

Stop the present derivation when its result is sufficient for the next decision. Further information or a physical trial is a separate action whose value depends on what remains unresolved. A concise explanation of the compared transformation and controlling premise is enough when it allows the intended user to continue.
