Formalization <-> Simulation Bridge ​

Bidirectional Traceability Between Mathematical Objects and Discrete Numerical Solvers

Spine Position

Mathematics Root · Formalization ↔ Simulation Diagnostic Mapping

Public Status Boundary. This bridge connects abstract formal mathematical specifications (F-class objects, candidate theorems, Lean 4 proofs) to discrete computational testbeds (finite-difference solvers, lattice automations, and operator resolvent packages). Computational simulation outputs stress-test mathematical invariants; they do not replace formal mathematical proofs or assert empirical confirmation.

The Formalization ↔ Simulation Bridge establishes explicit bidirectional mapping between abstract formalization layers and executable numerical engines. It enables researchers to visually verify which mathematical invariants are actively stress-tested and identify orphaned formal objects or ungrounded simulations.

3. Structural Demarcation ​

3.1 Formal Mathematical Layer ​

The foundation consists of F-class formal objects (axioms, definitions, invariants, and Lean 4 machine-verified lemmas). These objects define the rigorous variational and topological constraints that any physical state transition must obey.

3.2 Discrete Simulation Layer ​

The execution layer consists of computational solvers and lattice engines (e.g., KP-field elliptic-hyperbolic solvers, hydrogenic TDSE solvers, and FQFT metric measure testbeds). These prototypes generate quantitative residual bounds for empirical falsification and numerical consistency checks.

3.3 Mapped Bridges vs Open Gaps ​

  • Mapped Bridges: Signify that an active, versioned data pipeline exists connecting a formal invariant to an automated testbed (e.g., THM-FABRICA-CYCLE-01 → 1-Cycle simplicial boundary checks).
  • Open Gaps: Highlight theoretical frontiers where a candidate theorem lacks a numerical solver, or where a computational benchmark requires formal invariant axiomatization.
