This paper examines capability transfer from meta-research to domain research in a transcript-sufficient research system. Its case is P21, "From Brain Types to Network-Control Phenotypes," interpreted not principally as a biology paper in isolation, but as the first successful domain-science export of the Reflexive Laboratory. The central claim is that P21 became possible only after the laboratory had achieved a high degree of structural explicitness: bounded corpus formation, governed artifact relations, registry state, snapshot reconstruction, and transcript-visible review procedures. Under those conditions, the laboratory no longer functioned merely as a site for methodological reflection or infrastructure design; it acquired the capacity to generate, stabilize, and evaluate a substantive scientific model outside the meta-level. P23 therefore treats the transition realized in P21 as a methodological event: the conversion of research-system organization into domain-modeling power. The paper argues that this transition has broader implications for AI-assisted research, suggesting that credible domain contribution depends on corpus maturity, governance visibility, and explicit review pathways rather than generation alone.
