ComplexProjectiveSpace.lean — CP^n as a Kähler manifold
Full construction: homogeneous coordinates → standard atlas →
smooth complex manifold → Fubini-Study Kähler metric.
Replaces the cp_FS_Kaehler CONJECTURE axiom in UnifiedCovariant.lean.
Patterned after Mathlib Geometry/Manifold/Instances/Sphere.lean.

EisensteinSeries.lean — Modular Forms Stub Infrastructure
STATUS: SCAFFOLD — all theorems are HONESTY CLASS: CONJECTURE.
Full formalization requires the Mathlib modular forms module (T2.1 in
mathlib_missing_machinery.md). This stub provides the type signatures
and honest CONJECTURE axioms so the codebase compiles honestly while
waiting for Mathlib.
References:
Diamond-Shurman, "A First Course in Modular Forms", §4
Serre, "A Course in Arithmetic", Ch. VII
Koblitz, "Introduction to Elliptic Curves and Modular Forms", Ch. III
Mathlib already has:
- UpperHalfPlane (H := {z | im z > 0})
- ModularGroup SL(2,Z) action on H
- ArithmeticFunction.sigma (divisor sum) = σ_k(n) — PROVEN multiplicative
- EisensteinSeries/QExpansion.lean (partial — q-expansion coefficients)
What's MISSING (T2.1):
- M_k(SL(2,Z)) as finite-dimensional C-vector space
- Eisenstein series E_k for all even weights k ≥ 4
- Proof that M_* ≅ C[E_4, E_6]
- Rankin-Cohen brackets (for E_4^2 = E_8 identity)
- Hecke operators

The q-expansion of E_k gives divisor sum coefficients:
E_k(z) = 1 + c_k·Σ_{n≥1} σ_{k-1}(n)·q^n

/-- HONESTY CLASS: CONJECTURE
The weight-4 Eisenstein series squaring identity:
E_4^2 = E_8 in M_8(SL(2,Z)).
At the Fourier coefficient level, this yields the e8_convolution_identity.
This is the single most important missing theorem for the number theory
bridge between the E8 lattice and the Sidon set construction.
Expected to be proven once Mathlib has Rankin-Cohen brackets. -/

SidonAdapter.lean — Singer Construction → ManifoldShortcut Pipeline
Bridges the proven Singer construction (F_{p^3} Galois field → Sidon sets,
SidonSets.lean, 0 sorries) into the ManifoldShortcut dense-grid search
(ManifoldShortcut.lean, 0 sorries).
For each prime p, the Singer construction yields a Sidon set S of size
p+1 modulo p²+p+1. This adapter wraps S as a ManifoldEquation candidate
and provides a CandidateIterator for the shortcut search loop.
The pipeline:
PrimeEnumerator → SingerConstruction → ManifoldEquation → isShortcut → Admit
Connection to the Erdős Problem 30:
h(N) = max |A| for A ⊆ {1,...,N} Sidon
Singer: h(p²+p+1) ≥ p+1 ≈ √N (lower bound)
Lindström: h(N) ≤ √N + O(N^{1/4}) (upper bound, also in SidonSets)
The shortcut search finds the ACTUAL optimal Sidon set for a given N,
not just the asymptotic bound.

- Spectral cost ~ 1/k (sparser = easier to recover)

/-! ## §2 Lagrangian for Sidon Sets
The Lagrangian for a Singer-based Sidon candidate:
L = delta + α·spectral + β·program
Since Sidon sets are maximally sparse:
delta ≈ k/√M ≈ 1.0 (near-optimal by construction)
spectral ≈ 1/k (low = sparse = recoverable)
program ≈ log₂(p) (the generating prime in bits)
The search goal: find the prime p that produces the Sidon set with
minimum L — the one that maximizes k/√M (close to 1.0) while
minimizing program cost (small p preferred).

UnitDistCandidateGen.lean — Unit-Distance Point Sets → ManifoldShortcut
The Erdős unit-distance problem: what is the maximum number of unit
distances among N points in the plane? The known bounds are:
u(N) ≤ O(N^{4/3}) (Spencer-Szemerédi-Trotter bound)
u(N) = N^{1 + c/log log N} (best known lower bound)
For a dense grid of point configurations, the ManifoldShortcut uses
golden-angle perturbation to walk the configuration space efficiently.
Each perturbation moves one point along the golden spiral (φ⁻¹ contraction,
Kähler gate from GoldenSpiral.lean).
The ManifoldEquation for a point set:
- delta = optimal bound - achieved (gap to SST bound)
- spectral = 1/rank (sparser configuration = better)
- program = encoding cost of N points
- coherence = angular uniformity of the unit-distance graph
- rank = number of distinct distance classes
AngrySphinx bounds the search: each point perturbation costs 2^depth.
The NaN boundary terminates when the configuration converges.

A configuration of N points in R² with unit distances has:
- u(N) = number of unit-distance pairs
- SST bound: u(N) ≤ c·N^{4/3} (the optimal for this N)
- The coherence is the angular uniformity of the distance graph
- Spectral cost ~ 1/u(N) (more distances = sparser structure)
- Program cost = 2*N*log₂(N) (encoding the point coordinates)

/-! ## §2 Golden-Angle Perturbation
The golden angle θ_g = 2π/φ² is maximally irrational. Perturbing
a point along the golden spiral ensures no alignment with any rational
symmetry axis — each configuration is maximally different from all
previous ones (observerless).
This uses GoldenSpiral.lean's phi_inv contraction.
-/
/-- Perturb one point in the set by the golden angle.
For a point at (r,θ) in polar coordinates, the perturbed point is
(r, θ + θ_g) if expanding, or (r/φ, θ + θ_g) if contracting.
Since we work in Lean with Q16_16, we approximate the perturbation
as a rotation by the golden angle fraction. -/

WeightCandidateGen.lean — cmix Weight Matrix → ManifoldShortcut
The cmix compressor has a 23×461 weight matrix (the "genome"). SVD of
this matrix gives 23 singular values — the "compression shape equation."
If 5 singular values capture 95% of energy, the search space is 5D.
For each candidate weight configuration in the 5D SVD subspace:
1. Project to a full 23×461 weight matrix
2. Compute compression performance (coherence)
3. Wrap as a ManifoldEquation
4. Feed into the ManifoldShortcut search loop
Connection to the epigenetic framing (cmix_epigenetic_analysis.md):
- 461 models = 461 genes
- 23 layer-0 mixers = 23 regulatory regions (rank)
- 5 active singular values = the search subspace (sparsity)
- SVD spectrum = the compression shape equation (Lagrangian)
AngrySphinx bounds the search: each weight candidate costs 2^depth.
The NaN boundary terminates when the 5D subspace is exhausted.

The search walks the 5D SVD subspace. For each point in the subspace:
1. Reconstruct the full 23×461 weight matrix via U*diag(s)*V^T
2. Measure compression performance on held-out data
3. Compute coherence (accuracy vs previous best)
4. Wrap as ManifoldEquation and evaluate
Since full cmix evaluation (~10 hours) is impractical for the search,
we use a lightweight proxy: the singular value entropy.
Lower entropy = more concentrated spectrum = better compression.
-/
/-- Singular value entropy proxy for compression quality.
Entropy = -Σ (sv_i / Σsv) * log(sv_i / Σsv).
Lower = more concentrated = better compression.
Approximated in Q16_16 as: Σ(sv_i * log₂(sv_i/Σsv)) / (k * Σsv).
For simplicity, we use a heuristic: the ratio of top-1 sv to sum.
Higher ratio = more concentrated = better compression. -/
