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

State whether the judgement rests on an expert walkthrough, an actual reading, or a formal-model estimate, using the distinctions in C.2.8:4.5. An expert can judge recoverability from the public text for the intended reader. An actual response establishes what that reader recovered under those reading conditions. A formal-model estimate retains its stated observer, selected structure and model conditions under C.2.8:4.6.

Use expert reading for a bounded wording judgement when it resolves the question from the permitted public inputs and no actual response is required. Obtain actual public-only recovery when:

  • the intended conclusion claims that a reader actually recovered the instruction;
  • plausible reconstructions still differ in an action-changing participant, operation, result or condition, and the reader's response can change the repair or use decision;
  • it remains materially uncertain whether the publication supplies the needed instruction or the evaluator supplies it from private knowledge or test-only explanation; or
  • demonstrated misses undermine the sufficiency of the earlier expert reading for the affected instruction family.

A visible wording defect can be repaired directly. Select any reading still needed for the repaired text and intended conclusion. Give a cold reader the publication, its stated prerequisites and task inputs, withholding private rationale and suggested answers. Preserve the initial recovery before supplying further explanation; qualify subsequent source returns or help under C.2.8:4.3.

Limit a recovery conclusion to the natural text units and relations examined under its actual evidence basis. A whole-publication conclusion needs coverage of the whole publication, including relations needed to read its parts together. Successful application probes cover their tested uses; they leave unexamined text outside that result. A whole expert reading combined with local actual readings retains that mixed basis. Reuse a result for the same or explicitly unaffected text, recovery question, reader preparation, access, assistance and budget when those conditions still apply. A local revalidation by a reader familiar with the earlier wording retains that qualification.

State a material limit in the receiving judgement or result already needed by the work. When a required reading is unavailable, identify the missing basis and leave only the dependent conclusion open. Correct recovery of what the text asserts and the subject-matter warrant or practical adequacy of that assertion remain separate questions under C.2.8.
