openresearch 4141597e89 feat: experiment results — HN spectral database + q-profile sweep
Adds measured results from two CPU runs:

1. HN spectral database (run 019f2c52):
   Hoffman bound on 6 graphs. Tight for regular (path, cycle, complete),
   gap=1 for unit-distance (Moser spindle, Golomb graph). Pattern
   suggests spectral detection loses exactly 1 color for unit-distance graphs.

2. q-profile sweep (run 019f2d9c):
   Sweeps q = L₁/L₀ over coprime fractions. REFUTES the prediction
   that q < 1 (poloidal-dominated) is Sidon-favorable: q > 1 has
   100% Sidon rate vs 40-60% for q < 1. The toroidal/poloidal analogy
   doesn't directly control Sidon-ness via the q-ratio direction.

   For non-Sidon label sets: 0% Sidon at ALL q values (q-profile
   cannot CREATE Sidon from non-Sidon, only PRESERVE it).

All scripts, formal modules, and docs already committed to main.
This commit adds the experiment artifact JSONs and EVALs.

Predictions Tested

  1. q < 1 (poloidal-dominated) should have higher Sidon rate than q > 1

    • This is the toroidal/poloidal refinement prediction
    • If confirmed: poloidal resolution matters for Sidon structure
  2. Simple rational q should have LOWER Sidon rate than non-simple q

    • This is the R2 cross-pair coprimality prediction
    • Simple rationals = resonant surfaces = Sidon collapse
  3. Best q should be < 1 and not a simple rational

    • Optimal q-profile is poloidal-dominated and irrational
