What this page is
This is generated FPF reference text from the specification preface or supporting sections. It helps interpret FPF; it is not FPF Reference product documentation.
Methodology
Use it to understand how the specification wants to be read, then return to a route, pattern, or work packet for active work. Cite generated IDs only when the wording changes the task decision.
Content
A FunctionalStructureView under C.30.ASV may cite ArchitectureTransformationFlowStructureRelation when a transformation-flow use is current. That record does not make the selected E.18 structure a functional element or actual transformation, and does not make a functional-element claim identical with the system, module, method, bearer, or flow. It states a bounded claim or trace that exact functional-view content corresponds to, is declared relative to, or positively co-refers with one exact E.18 selected structure, member-local path, crossing, or valuation.
Keep the same three branches used by C.30.ASV:
functionalBehaviorClaimRefsandrequiredOrDesiredEffectClaimRefsremain C.2.1 claim content under their requirement, architecture, capability, method, functional-view, or other direct owner;actualTransformationRefscite only independently identified A.3.4 occurrences with exact changed referent, boundary or extent, boundary conditions, actual before/during/after facts, and continuity or reidentification basis;selectedTransformationFlowStructureRefscite exact E.18 structures, which may organize several independently identified transformations and transfers but are not themselves required effects or actual transformations.
A FunctionalElementClaim is a bounded C.2.1 claim about one exact selected functional structure. Its bearer or candidate-bearer locus, capability, port, allocation, transformation, and correspondence refs retain their direct owners. A graph-shaped expression, path, valuation, required-effect statement, or flow packet is therefore not the functional element by default.
Required-cooling-effect / later-actual-cooling countercase. RequiredCoolingEffect-1 can require exact Rack 7 to be below 30 °C and can correspond to a selected cooling-flow structure before any change occurs. In that first use, fill requiredOrDesiredEffectClaimRefs and the selected TFS fields; leave actualTransformationRefs empty. A later Rack7CoolingTransformation-42 is actual only when A.3.4 fixes Rack 7 as the changed referent, its thermal boundary and operating/ambient conditions, actual 38 °C before facts, actual heat-removal during facts, actual 27 °C after facts, and continuity or reidentification of Rack 7. Even then, a separate satisfaction or realization predicate is needed before claiming that the actual transformation satisfies the earlier requirement.
Use this note when the practitioner needs to see whether the function-to-transformation-flow relation changes inspection, split, relation-making, downgrade, claim-governance assignment named by value, candidate generation, or stop. Use C.30.ASV for the functional structure view, A.6.F for function-like wording recovery, A.3.4 for an actual transformation, A.6.M for module-claim repair and the direct allocation/interface owner, and E.18 for selected transformation-flow structure.
FunctionTransformationFlowRelationNote is the one-TFS form. When architecture use selects a network, use the top-level ArchitectureTransformationFlowStructureRelation and the branch in C.30.TFS-REL:4.4a. Name a member TFS in this note only when the function correspondence is actually to that member; membership in the selected network alone does not create a function correspondence.
When several transformation-flow variants are kept or compared as candidate architecture inputs, keep each selected transformation-flow structure, path, crossing, valuation, graph-shaped expression, or mathematical description under [E.18](/generated/patterns/E.18), [E.18.2](/generated/patterns/E.18.2), and this record. Apply [C.32](/generated/patterns/C.32) only to the architecture candidate palette that uses those selected structures. The graph, path, and flow description does not become architecture adequacy, evidence, assurance, gate passage, selected-set publication, or decision by serving as a candidate input.
