E.11:1 - Problem frame

E.11:1.1 - Use this when

Use E.11 when a pattern title, README scenario, Preface explanation, ToC cue, retrieval cue, lexical query row, expanded case, or pattern-local recognition passage could change which FPF pattern a working reader should inspect first.

The ordinary reader does not arrive with a PatternID. They arrive with a project question: architecture, a working document, a comparison, a vague concern, an improvement, evidence, timing, causal use, a description, a name, wording, mathematics, state of the art, a local framework, system recognition, or system delimitation. E.11 gives that reader a recognizable entry without turning entry material into a second pattern body or universal method sequence.

First useful result. The reader can name the working situation, the first useful result or blocker, one direct pattern or small plausible set to inspect, and the ordinary stop or wrong-turn return. That is enough for ordinary entry; no card form, comparison account, or project-local value is required.

Primary EntityOfConcern. One public entry or discoverability publication unit: pattern title, README first-entry guidance, Preface principle explanation, ToC query material, retrieval cue, expanded entry-disambiguation case, or a pattern-local Problem frame.

Author and reader remain different. An FPF author or maintainer publishes or refreshes the public guidance. A practitioner, manager, or assisting agent reads it and opens the direct pattern; that reader is not thereby performing E.11 publication work.

What this buys. A cold reader starts from a real project question rather than FPF topology, while exact pattern authority stays in the direct pattern and duplicate navigation canons do not grow.

Not this pattern when. After one direct pattern is selected, use E.11.PUA to follow its Solution to the smallest useful result or an honest missing-basis stop. Use E.11.PUR to judge applicability, recommendation, coordination, or ordering among candidate pattern uses, and to stop on an earlier result that still answers the concern. Use the direct pattern for the actual result, plan, work, evidence, decision, authorization, or publication claim.
