B.3.5:4.1 - Structural CT2R Typing-Grounding Unfolding Structure Block

When a constructive trace, working-model relation, and target kind or logical representation must be carried together across contexts, use this block or cite an equivalent A.22.CGUS specialization. The block is useful when the reader must see the passage from constructional material to a typed or logical claim without treating a readable relation label as proof.

StructuralCT2RTypingGroundingUnfoldingStructureBlock:
  unfoldingStructureRef: exact independently selected A.22 structure, when needed
  workingModelOrConstructiveRepresentationRef:
  targetKindOrLogicalRepresentationRef:
  bridgeRef?:
  constructiveTraceRef?:

  evidenceOrProofLinkageRef?:

unfoldingStructureRef names an independently selected A.22 structure; this block is a record describing its use. Recover the exact constituents, obtaining relations, applied constraints and named selection/use frame. StructuralCT2RTypingGroundingUnfoldingStructure is a local designator for the selected structure used to inspect this construction-to-typed/logical projection. Any A.22.CGUS qualification is tested separately under its potential-continuation rule; a local name or record does not establish it. C.13 supplies constructive-trace content and C.3 the kind intent, extent and subkind content actually used. The record creates no proof, empirical evidence, Work plan or decision.

When an inadequate working account requires general diagnostic recovery of the exact subject construction, use A.7.1. That return may stop at a direct relation, system-role assignment, state or capability, Work occurrence, holon recognition, or the pattern for another subject without opening this structural CT2R specialization.

workingModelOrConstructiveRepresentationRef names the relation, trace, model, or representation being carried. targetKindOrLogicalRepresentationRef names the typed or logical target. bridgeRef is required when this use actually claims or consumes an obtaining semantic Bridge under F.9 or a kind correspondence under C.3.3. CL_or_CLk is required when the consumed assurance/calibration account requires that value. Entity, scheme, plane or notation changes alone establish no crossing; a same-sense unit conversion requires neither invented endpoints nor a Bridge. CL does not by itself authorize use. preservedStructure and lostOrCollapsedStructure state what survives the passage and what the published relation no longer carries. Evidence linkage remains with B.3 evidence and assurance subject patterns; proof linkage remains with the proof or mathematical subject pattern that is current. The unfolding block only makes the structure of the passage inspectable.
