From Fold to Materials: An Exact, Parameter-Free and Machine-Closed Reconstruction of Materials Science from Smithian Fold Theory

From Fold to Materials, version 1.2.0, is the current-evidence-closed, extension-open Materials Science foundation of the Smithian Fold Theory V3 clean-room reconstruction. The release contains 92 engine-admitted laws generated from 23,552 exact candidates, with 92 unique survivors, 368 passing adverse controls, 92 implementation-distinct reconstructions and 92 post-seal NIST/BIPM comparisons. Every registered dependency graph reaches the single premise-free root theorem; no axiom, free or fitted parameter, forbidden proof value, imported constitutive law or target-selected survivor is admitted. Version 1.2 adds eight independently sealed and admitted V1/V2 reconciliation laws: exact aperiodic substitution with no positive rational fixed scale; acoustic/optical and thermal mode limits; p-n rectification; superconducting isotope-response provenance; ferrimagnetic unequal-sublattice support; integer and primary fractional Hall classes; exact topological edge-class counting; and a water bulk-response ledger tested against boiling, liquid/solid density and heat-capacity records. The release includes the paper in PDF and Markdown, the complete evidence map, claim packages, engine receipts, source snapshots, independent validators, atomic ownership audit and checksums. Closure is dated and extension-open: lawful additions, corrections and falsifications remain admissible through the same public engine.
