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.

# CRT q-Profile Safety Factor Sweep
**Experiment:** crt_qprofile_sweep
**Date:** 2026-07-04T14:52:24Z
**SHA-256:** `9e3c89352141e4d707215ef7b01b0eb1c70193d854774f7e2f4eaecd24fddfb4`
## Summary: Sidon Rate by q-Regime
| Label set | Total | Sidon | Rate | q<1 total | q<1 Sidon | q<1 rate | q>1 total | q>1 Sidon | q>1 rate | Simple q Sidon | Non-simple Sidon | Best q |
|-----------|-------|-------|------|-----------|-----------|----------|-----------|-----------|----------|----------------|------------------|-------|
| sidon_pow2 | 25 | 22 | 88.0% | 5 | 2 | 40.0% | 20 | 20 | 100.0% | 22 | 0 | 5/7 |
| sidon_singer5 | 25 | 23 | 92.0% | 5 | 3 | 60.0% | 20 | 20 | 100.0% | 23 | 0 | 3/7 |
| nonsidon_seq5 | 25 | 0 | 0.0% | 5 | 0 | 0.0% | 20 | 0 | 0.0% | 0 | 0 | 2/7 |
## 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
