C.22.PFR:4.2 - Keep the PFR signature reduced to two participants

Public name settlement. The following F.18 NameCard names the actual dependent evaluative relation kind.

NameCard:
  NameCardId: NC-PROBLEMATIC-FOR-RELATION
  GovernedValueRef: ProblematicForRelation under C.22.PFR
  SubjectPatternLocator: C.22.PFR
  ReferenceScheme: FPFCoreReferenceScheme
  LocalSenseRef: actual dependent evaluative relation with one actual-condition relation occurrence and one problem-criterion-applicability relation occurrence as its only non-derived participants, individuated by those participants plus the actual inception of each maximal continuous adverse episode
  TechLabel: ProblematicForRelation
  PlainLabel: actual problem
  CandidateSet: ProblematicForRelation; AdverseCriterionAssessmentRelation; ProblemUseRelation; ProblemRelation; ProblemSituationRelation
  RejectedCandidates: AdverseCriterionAssessmentRelation omits the problem-for relation; ProblemUseRelation hides the actual adverse condition; ProblemRelation hides criterion applicability; ProblemSituationRelation falsely requires situation
  SelectionRationale: make ordinary Problem recoverable without copying applicability participants and distinguish repeated adverse episodes without requiring a universal adverse-evaluation relation occurrence
  PublicRowStatus: pending
  LineageEntries: situation-first, card-as-world, bearer-duplicating, and description-edition identity proposals retired
  RefreshCondition: reopen if participant references plus actual adverse inception cannot keep one stable occurrence reference through closure or distinguish later adverse episodes, or if the predicate's condition-to-input rule no longer yields one unambiguous characteristic point and problem-for link

No-mint disposition for root U.Problem. Do not introduce a second problem entity beside the obtaining ProblematicForRelation occurrence. That occurrence is the actual Problem; a ProblemCard, criterion description, assessment claim, or local Plain label may describe or designate it but does not supply another world-side identity.

The complete non-derived participant set is:

ProblematicForRelation:
  ActualConditionRelationSlot: U.Relation, byRef
  ProblemCriterionApplicabilityRelationSlot: U.Relation, byRef

The first reference resolves to the exact obtaining relation that constitutes the actual condition under its direct pattern. The second resolves to the exact obtaining applicability relation from C.22.PFR:4.1.

PFR has no separately writable condition-bearer, predicate, problem-for-entity, claim-scope, applicability-window, assessment-window, or description-edition slot. The actual-condition relation fixes its condition participants, and the applicability relation fixes the predicate, problem-for entity, claim scope, and declared applicability window. Assessment windows and description editions remain with their own claims. A readable claim projects the applicability values from that participant:

PFR.problemCriterionPredicate
  := PFR.problemCriterionApplicabilityRelation.problemCriterionPredicate
PFR.problemForEntity
  := PFR.problemCriterionApplicabilityRelation.problemForEntity
PFR.predicateClaimScope
  := PFR.problemCriterionApplicabilityRelation.predicateClaimScope
PFR.declaredCriterionApplicabilityWindow
  := PFR.problemCriterionApplicabilityRelation.declaredCriterionApplicabilityWindow
PFR.problemCriterionApplicabilityExtent
  := maximal continuous obtaining extent of PFR.problemCriterionApplicabilityRelation

This is a derivation from one participant, not a consistency check between copies.
