C.32.ACS:4.4 - Improvement-cycle use

When a row is used inside an improvement cycle, add:

ArchitectureCharacteristicImprovementRow@Project:
  projectWorkOccurrenceRef?: U.EntityRef constrained to U.Work
  architectureCriteriaProjectUseRelationRef?: U.RelationRef governed by the exact improvement-row-use or work-use pattern
  criteriaRowRef:
  rowClaimScopeRef: U.EntityRef referencing one U.ClaimScope
  selectedContextSliceRefs:
  modelUseStructureRef?:
  effectiveReferenceScheme:
  referencePlane?:
  qualificationOrEvaluationWindow:
  useClass:
  currentArchitectureReadingRefOrQualitativeState:
  evalResultRefs?:
  intendedArchitectureChangeDirection:
  candidateSelectedStructureChangeRefs?:
  expectedGain:
  protectedLosses:
  observedReadingAfterChange?:
  nextSynthesisTrigger?:
  stopContinueOrSourceReturnCondition:

The row prepares improvement work. It does not carry a claim outside its declared scale and use. A reading or other typed eval result over a declared row retains its result kind and conditions; another pattern may use it as source material for bounded claim reliance under A.10, improvement feedback, comparison input, selection input, or decision input only when that pattern for the next question is named by value. It does not become the characteristic, the declared architecture concern, the architecture choice, or the optimization direction.
