SIE.2:1 - Problem Frame
Use this when a bounded integration use exists, yet endpoint meanings are being inferred from labels, column names, class names, diagrams, sample values, or undocumented organizational knowledge. The recognizable failure is a mapping that runs while joining different concepts, editions, grains, or authority scopes.
The primary EntityOfConcern is the set of source-local semantic premises that the receiving use actually consumes. The first move is to select one load-bearing source asset and recover its scheme, edition or effectivity, meaning, owner, authority, provenance, and access conditions. The first result is an inventory that makes both usable premises and exact gaps inspectable.
The payoff is a clean separation between what a source says, what an integrator infers, and what another owner must decide. Do not use SIE.2 to construct an ontology, establish a cross-source correspondence, decide identity, fuse claims, or judge receiving-use adequacy. If model adequacy for a required distinction remains unsettled, request UseFitSemanticModel@Use from SIE.3 or another qualified direct provider. Adequate reuse can finish that question; an actual missing distinction may require extension or construction.
