Add two Lean modules projecting the Menger/Koch/Gabriel-Horn fiber model
onto DESI DR2 cosmological observables:
- DESIInvariant.lean: Hardcoded DESI DR1/DR2 constants as Q16_16 Int
literals. Zero Float arithmetic. 7 observational parameters + sigma
bounds. 5 native_decide theorems. 7 eval! receipts.
- DESIModelProjection.lean: Maps 16D model predictions onto DESI
observables. 4-component residual computation with verdict
classification. 17 native_decide theorems proving:
* All 4 observables within 1s of DESI DR2
* Directional agreement on w0 > -1, wa < 0
* Menger/Koch geometric facts (d_H < 3, D_K < d_H, divergence > 1)
* Horn volume bounded, surface grows, torsion drives boundary

0-Core-Formalism
Purpose: Formal foundations for the entire Research Stack — Lean modules, bind primitive, Triumvirate consensus, core source.
No external dependencies. All other layers depend on this.

Concepts
- bind — State → (State → Action) → State
- TriumvirateClock — ternary consensus (ADD/PAUSE/SUBTRACT)
- Builder/Judge/Warden — roles mapped to hardware registers
- OTOM — Ordered Transformation & Orchestration Model
