E.9:1 - Problem frame

FPF is engineered for Pillar P‑10 Open‑Ended Evolution: its normative rules must adapt as new calculi and insights arrive. But change without a recoverable selected answer and rationale leads to conceptual erosion, while a formally rich record can still defer the decision or distribute a harmful rule. Hence FPF uses a Design‑Rationale Record (DRR) as a durable conceptual record that fixes one bounded content decision before its normative change is distributed.
