C.22.2:2.3 - Relation Boundary Aid

Use this aid only after the Thin ProblemCard is legible: signal, joint EntityOfConcern, effective ReferenceScheme, ClaimScope, claim family, not-wish reason, improvement check or acceptance probe, and honest next use. It is not a second writing order and not a catalogue of other patterns. It answers one question:

Which claim being made, relation, or boundary changes the problem-card use, and which FPF pattern defines or constrains that claim, relation, or boundary?

If the claim, relation, or boundary does not change the current problem-card use, leave it out of the card. If it does change the move, keep only the local cue or reference that makes the card reviewable, then apply the subject pattern for that claim, relation, or boundary.

Current claim, relation, or boundary that changes the card useLocal ProblemCard contentSubject pattern
Characterization, measurement, indicator, Q-bundle, comparison, acceptance, or parityCharacterization cue, acceptance probe, candidate criterion, comparator cue or window cue, and the current reason the relation changes the problem formulation.C.16, A.19, C.25, G.0, G.4, or G.9 according to the relation named by value.
Archive, pool, front, shortlist, selected set, retained candidate, or set-return sourcesourceSetRef, source-set kind, selection or retention criterion, budget or window when current, and non-scalar next use.C.18, C.19, G.5, G.9, G.11, A.6.P:7a, or C.16.Q according to the relation named by value.
Method family, work planning, work-entry readiness, performed work, result record, evidence, provenance, assurance, gate, or autonomyProblem-side cue, source reference when it changes formulation, and stop condition before that outside use.G.5, A.15, A.15.5, A.10, G.6, B.3, A.21, or E.16 according to the claim named by value.
Temporal, causal-use, representation-transition, retargeting, bridge, structural-reinterpretation, or wording-use relationRelation reference plus the inheritance boundary: what can be reused from the old card and what relation is reopened.C.27, C.28, A.6.3.RT, A.6.4, E.17, F.9, E.18, or E.10 according to the relation named by value.
First-principles or mathematical structure cueCandidate structure, preserved and lost structure when current, practical payoff for problem formulation, problem-formulation follow-up reason, and stop condition.C.29 for mathematical-lens use; A.6.0 for a FormalSubstrate U.Signature declaration when that signature declaration is current.
Agentic safe probe or world-affecting next actionProbe need, risk condition, bounded next action, and the safety, autonomy, gate, work, evidence, or assurance claim kind that blocks local action.C.24, E.16, A.21, A.15, A.10, G.6, or B.3 according to the relation named by value.

Over-capture symptom: the practitioner spends the pattern use classifying FPF patterns while one or more core Thin items in C.22.2:2.1 remain unstable.

Repair: return to the exact Thin form in C.22.2:2.1 and complete only its core items. Reopen this aid only for the claim, relation, or boundary that changes the honest next use.
