# Super-enhancer Model of Cell Identity

Super-enhancer labels identify many important regulatory regions, but native perturbations favor heterogeneous local grammar over a uniquely distinct cell-identity control class.

The registered weakest-link returns Β from SC1 and SC2. SC1 is a reproducible operational association, not evidence for qualitative causal class distinction. SC2 has local mechanistic plausibility at Γ, but one native class-distinction prediction challenge lowers it to Β: called clusters can be dispensable while conventional elements are strongly required, and additive/hierarchical or facilitator rules explain many effects. Native nonadditivity is retained and a universal additive counterclaim is rejected. SC3 is Γ for the prespecified distinct-class disproportionate identity claim, while individual native lineage dependencies have real context-specific causality.

Normal mammalian lineage dependence, terminal output and tumor fitness are separate scopes. Locus, stage, calling parameters and promoter compatibility are specified before response. Conserved selected pluripotency elements do not represent all clusters. No responder-defined class is manufactured, and no physiological lineage is inferred solely from a nearby gene name.
