  "title": "Separate opposite requirements by condition",
  "summary": "The answer may be 'both,' provided the system knows when each one applies.",
  "kind": "heuristic",
  "body": "Name the condition that changes which property is desirable, then make system behavior conditional on it. Prefer a condition that is observable before the action. This can replace one compromised default with two explicit policies.",
  "limits": [
    "Conditional rules can become complex and inconsistent; keep the condition set small, testable and auditable."

      "note": "These are solution-search heuristics; implementation still needs domain evidence, safety and feasibility checks.",

    "The system needs different behavior depending on state, risk, load, user or another observable condition."

  ],
  "example": "Allow automatic deployment for low-risk changes that pass defined checks, but require human approval for high-impact permission or schema changes.",
  "check": "The system has an observable condition that determines which opposite behavior applies.",
