20.5 Three foundry case studies

The same architecture becomes concrete in very different domains. Health research stresses population, intervention, and safety qualifiers. Corporate filings stress source anchors, units, periods, and narrative–numeric agreement. Product research stresses identity, review heterogeneity, and transport between consumer, store, brand, and corporate contexts.

The evidential unit in these studies is an artifact record, not a generated sentence scored in isolation. Each record carries a source identifier and span, local type and scope, restriction outcomes, argument status, admission decision, and refresh obligation. Counts below are descriptive audit totals from frozen foundry runs. They establish that the architecture can preserve and expose these distinctions; they are not estimates of population-level answer accuracy, causal correctness, or professional decision quality.
