#G.9:2 — Problem frame

Preface node heading:g-9-2-problem-frame:82934

#What this page is

This is generated FPF reference text from the specification preface or supporting sections. It helps interpret FPF; it is not FPF Reference product documentation.

#Methodology

Use it to understand how the specification wants to be read, then return to a route, pattern, or work packet for active work. Cite generated IDs only when the wording changes the task decision.

#Content

Parity claims become non‑reproducible or non‑comparable when any of the following are implicit:

• evidence window / freshness regime,
• comparator semantics (including any normalization / comparability mapping),
• method‑family “measurement” edition pins (incl. DHC method/spec),
• cross‑Context reuse (Bridge refs, crossing pins, and CL penalty placement),
• dominance and PortfolioMode interpretation rules,
• gate outcomes (why a run abstained or degraded).

G.9’s role is to make these recoverable as pinned and publishable as a method of obtaining outputs (MOO) without introducing new governing spec refs.
