# Documentary-Structural Inference **Entity class:** Research method **Domain:** Intelligence history / clandestine-systems analysis ## Definition **Documentary-structural inference** reconstructs a partly hidden system from public institutions, procurement records, statutes, declassified precedents, capability requirements, labor pools, and documented interfaces. It asks which unobserved arrangements are compatible with observed outputs and which arrangements the documented machinery requires. Secrecy is not evidence. It explains why a channel may be dark; confidence must come from independent constraints visible in the remaining record. ## Relationships - **conditions:** [[wiki/Visibility Asymmetry|Visibility Asymmetry]] and intentional information denial. - **uses:** documented fact, strong structural inference, plausible inference, and speculation as separate claim states. - **applied to:** [[wiki/Performance Labor and National Security|Performance Labor and National Security]] and the [[wiki/Performance-Labor Pathway Family|Performance-Labor Pathway Family]]. - **source:** [[research/The Producer Function in Intelligence Tradecraft and Dramaturgy|The Producer Function in Intelligence Tradecraft and Dramaturgy]].
