Primitive Carriers, Derivative Skins, and Classifier-Level Prediction Closure in the Standard Model

This paper opens the Standard Model Carrier Exhaustion ARC by establishing the master classifier for Standard Model standing. Its central distinction is between primitive carriers, which supply admissible standing for a Standard Model-associated claim, and derivative skins, such as field presentations, particle labels, mass values, couplings, gauge choices, measurement routes, anomaly displays, effective-field-theory terms, projections, or model names. The paper argues that no such presentation-level object receives primitive status merely by appearing in accepted Standard Model discourse. Instead, each candidate must pass a carrier-admission discipline that separates primitive role occupation from derivative representation. Within the ARC, SM-1 functions as the classifier-level entry point. It defines the Standard Model claim arena, introduces the component normal form used by later papers, gives the master classification protocol, and fixes the no-promotion discipline that later sector papers apply to gauge carriers, matter carriers, charge and coupling transport, flavor and mixing, and final Standard Model carrier exhaustion. Its contribution is therefore not a new phenomenological fit or a replacement for Standard Model physics, but a structural audit of what counts as primitive, derivative, update-bearing, projection-bearing, or extension-bearing within a non-degenerate Standard Model claim regime. Position in the ARC SM-1 is the foundational classifier paper for the Standard Model ARC. It does not yet close the gauge, matter, charge, flavor, or generation-cardinality sectors individually. Instead, it supplies the rulebook that later papers instantiate: SM-1: master classifier and primitive/derivative distinction. SM-2: gauge-carrier instantiation. SM-3: matter-carrier instantiation. SM-4: charge, coupling, and renormalization transport. SM-5: flavor transition, mixing, and generation-cardinality preparation. SM-6: full Standard Model carrier-exhaustion closure. Generation-cardinality extension: endpoint closure of forced role-occupancy cardinality.
