E.19:1 - Problem frame
FPF evolves by adding and revising patterns. Over time, the framework accumulates two kinds of risk:
-
Admission risk — a newly authored pattern can be structurally compliant yet still fail on ontology, semantics, terminology conflicts and vagueness, scope, SoTA in related disciplines, or cross-context hygiene.
-
Staleness risk — older patterns can remain internally consistent while drifting away from contemporary practice and newer parts of FPF, current internal vocabulary, or updated related patterns and their defining or constraining content. The result is “quiet decay”: the pattern still appears clear, but becomes misleading, incomplete, or incompatible.
FPF already contains many checklists and constraints, but they are distributed across patterns and suites. Authors and reviewers therefore lack a single, repeatable way to answer: What should be checked, and how deep, before a pattern is admitted or kept?
