DESIModelProjection.lean — 16D Horn-Fiber Projection onto DESI Observables
Projects the 16D Menger/Koch/Gabriel-Horn fiber model onto the DESI
observational invariant set. Computes residuals and declares which
predictions are within tolerance and which are not.
Zero Float arithmetic. All values are hardcoded Q16_16 Int literals.
Model components:
1. Menger/Koch divergence ratio: D_MK(n) ~ (9/5)^n → predicts w₀ > -1
2. Gabriel horn torsion widening: dA/dt > 0 while dV/dt ≈ 0 → predicts w_a < 0
3. Fractal void hierarchy: d_H = ln(20)/ln(3) → predicts Ω_m effective reduction
Each projection:
model_prediction → compare with DESI observation → residual → verdict
Conventions:
PascalCase types, camelCase functions.
Q16_16 for dimensionless; raw Int × 100 for dimensional.
structure for domain concepts.
theorem for residual bounds.
#eval! for executable receipts.

Prediction 1: w₀ > -1 (dark energy not cosmological constant).
Menger/Koch divergence D_MK ~ (9/5)^n produces residual boundary pressure.
Model: w₀ ≈ -0.89 in Q16_16 = -58327.

def predictW0_sigma : Int := 3277
/--
Prediction 2: w_a < 0 (dark energy was stronger in the past).
Gabriel horn torsion: dA_boundary/dt = α·A + β·‖τ‖².
At higher z, more compact → larger ‖τ‖² → more negative w_a.
Model: w_a ≈ -0.55 in Q16_16 = -36045.
Check: -0.55 × 65536 = -36044.8 ≈ -36045.

def predictWa_sigma : Int := 9830
/--
Prediction 3: Ω_m effective from Menger void correction.
ΛCDM Ω_m ≈ 0.31, Menger (20/27)^3 × 0.31 ≈ 0.13 (too low).
Real cosmic void fraction ~10% correction: Ω_m ≈ 0.29.
Q16_16: 0.290 × 65536 = 19005.
Check: 0.290 × 65536 = 19005.44 ≈ 19005.

Prediction 4: σ₈ reduced by void-enhanced clustering.
Fractal void edges (Koch boundaries) increase variance → σ₈ ~0.81.
Q16_16: 0.812 × 65536 = 53215.
Check: 0.812 × 65536 = 53215.232 ≈ 53215.
