5a890d4b9a chore: QC cleanup — create Q16Utils, remove dead code, consolidate proofs 
NEW: Q16Utils.lean — shared scale, absDiff, q16Mul, q16Div removed from 6 files

HIGH (4 fixed):
  H1: absDiff now shared from Q16Utils (was in 4 files)
  H2: scale now shared from Q16Utils (was in 6 files)
  H3: 2 duplicate theorems removed (AdjacentCoprimeClassification)
  H4: dead q16_div removed from DESIModelProjection

MEDIUM (4 fixed):
  M5: dead DESIParam removed from DESIInvariant
  M6: q16Abs kept (Int.abs not available in Lean 4.30)
  M7: 6 dead structures removed from DESIModelProjection
  M8: 40 theorems consolidated into 5 ∧ chains (AdjacentCoprimeClassification)
  M9: q16Div now shared from Q16Utils

LOW (2 fixed):
  L11: SuperpositionalBoundaryLayers now uses shared Q16Utils
  L12: SCALE → scale in SuperpositionalBoundaryLayers

d8047fbe30 feat(physics): DESI invariant and 16D horn-fiber model projection 
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

a06cf96d30 Add C¹-continuous Hermite spline bridge for 16D Reynolds regime transition 
Implements the UniversalBridge module in Lean with Q16.16 fixed-point
arithmetic, connecting the laminar exit (Re=2300, f=0.0278) and turbulent
entry (Re=4000, f=0.0398) with provable C¹ continuity.

Includes 24 verification theorems (boundary conditions, basis function
values, regime classification, controller gate semantics) and 10
executable #eval! witnesses as computational receipts.
