Reflexive Reality: A Philosophical Exposition What the NEMS Research Program Tells Us About the Deepest Questions

This paper is Paper C1 (capstone exposition) of the NEMS Suite; it follows the formal paper sequence Papers 0–85 in substance, while the source folder prefix 86_ places it next to Paper 85 for browsing. It is written for the philosopher, scientist, and intellectually serious non-specialist. Technical results from across the suite are cited with bracketed codes, with sketch-proofs that anyone can follow. Every major load-bearing claim marked with a citation such as P63 or RP-RI corresponds to a machine-checked theorem proved with zero sorry in Lean 4, under the umbrella program. To verify claims: lake update; lake exe cache get (when recommended) ; lake build (default target ReflexiveReality). To check a named alias exported through Philosophy. lean: open a Lean session in that repository and run #check Philosophy. TheGoldenBridge (example). The Formal Verification Index () maps bracket codes to theorem strings and libraries. Trust boundary. Not every sentence is a Lean proposition; theorem-extracted, bridge, and interpretive levels are distinguished in Part I. Bracket-tagged load-bearing claims are the audit targets; see.
