  "title": "Separate stock from flow",
  "summary": "Stocks remember history; flows change stocks.",
  "kind": "principle",
  "body": "Identify what accumulates and which inflows or outflows alter it. This prevents treating a large backlog as if it were only today's arrival rate.",
  "limits": [
    "A causal map is a hypothesis, not proof. Keep evidence, time scale, boundary choices and alternative explanations visible before acting on a loop."

  "evidence": [
    {
      "claim": "System dynamics work emphasizes that well-intended interventions can be defeated by feedback-driven system responses, a pattern described as policy resistance.",
      "source_id": "RS-592B2C21A3CDE468",
      "role": "supports",
      "note": "A qualitative feedback story is not enough; links, delays and predicted behavior still need empirical or operational checking.",
      "locator": "Abstract"
    }
  ],
  "use_when": [
    "When a system has accumulation, backlog, inventory, skill, debt or another quantity that changes over time."
  ],
  "avoid_when": [
    "A causal map is a hypothesis, not proof. Keep evidence, time scale, boundary choices and alternative explanations visible before acting on a loop."
  ],
  "example": "Unresolved defects are a stock; new defects and reopens are inflows, verified fixes are an outflow.",
  "check": "The map distinguishes accumulated quantity from rates that change it.",
