apply-separation-principle

Purpose

Resolve a physical contradiction by separating conflicting requirements in time, space, scale, condition, or system level.

Input contract

required: [contradiction, conflicting_requirements]
optional: [system_boundary, operating_conditions]
constraints: [requirements must be stated as mutually conflicting outcomes]

Procedure

1. State the useful and harmful effects that cannot coexist (conflicting_requirements).
2. Test separation in time, space, scale, condition, and system level.
3. Select the separation that removes the conflict and state its operating condition.

Output contract

produces: [separation_candidates, selected_principle, operating_condition]
delta_fields: [findings, hypothesis_updates, decisions, uncertainties]

Quality gates

• Each candidate names the separated dimension and preserves the useful effect while removing the harmful one.

Failure and counterexamples

Do not call parameter tuning a separation when both requirements still occur under the same condition.
