The institutional record
The eight-decade spine of official U.S. government UAP study — Project Sign (1947) through AARO (2022– ). Documented beyond dispute even where its conclusions are contested. The structure worth seeing: it's one loop run twice — study → debunk → close, then revive → acknowledge → institutionalize, forty years apart.
Methodology — the rigor turned on the record
The lineage is modeled three ways on the spine concept:
a statechart of the policy arc, a Petri net of the
recurring burial/disclosure cycle, and an evidence poset of the modern
multi-sensor cases.
