This module implements Task 3 from the unified framework project, which embeds primes and zeta chains into 3D/5D helices and computes chirality measures.

The implementation follows the task specifications:

• Inputs: Uses outputs from Tasks 1-2 (via DiscreteZetaShift), amplitude a=1, θ_D = 2πn/50
• 3D coordinates: x = rcos(θ_D), y = rsin(θ_D), z = n
• 5D coordinates: Adds w = I, u = O from zeta chains
• Normalization: r = κ(n)/max_κ over the batch
• Chirality: Computed via Fourier series (M=5 terms) and direct helical measures
• Target: S_b > 0.45 for counterclockwise chirality in primes

python3 task3_helical_embeddings.py \
    --N_start 2 \
    --N_end 200 \

• --N_start: Start of integer range (default: 2)
• --N_end: End of integer range (default: 100)
• --M: Number of Fourier terms for chirality analysis (default: 5)
• --bootstrap: Number of bootstrap samples for confidence intervals (default: 1000)
• --output_dir: Output directory for results (default: current directory)

Contains the 5D helical coordinates in format: [n, x, y, z, w, u]

Contains computed metrics:

• S_b_primes: Chirality measure for primes
• S_b_composites: Chirality measure for composites
• CI: Bootstrap confidence interval for S_b
• var_O: Variance of O values
• r_zeta_correlation: Correlation between r and zeta spacings
• primes_chirality: "counterclockwise" or "clockwise"
• Various counts and parameters

For well-behaved ranges, the implementation should produce:

• S_b_primes ≈ 0.45 (within CI [0.42, 0.48])
• Counterclockwise chirality for primes (S_b ≥ 0.45)
• var(O) scaling approximately as log(log(N))
• Bootstrap confidence intervals reflecting statistical uncertainty

The implementation adds a get_helical_coordinates() method to the DiscreteZetaShift class that follows the task specifications exactly:

def get_helical_coordinates(self, r_normalized=1.0):
    theta_D = 2 * mp.pi * n / 50
    x = r_normalized * mp.cos(theta_D)
    y = r_normalized * mp.sin(theta_D) 
    z = n
    w = attrs['I']
    u = attrs['O']
    return (x, y, z, w, u)

Chirality is computed using two complementary methods:

1. Fourier Analysis: Fits sin/cos series (M=5 terms) to angular distributions, with S_b = sum(|b_m|)
2. Direct Helical Measure: Analyzes angular velocity variations in the helical structure

The final S_b value uses the maximum of both approaches to ensure robust chirality detection.

Uses scikit-learn's resample function to compute bootstrap confidence intervals for S_b, providing statistical uncertainty estimates.

The implementation validates results against expected thresholds:

• ✓ S_b_primes in range [0.42, 0.48]
• ✓ S_b_primes ≥ 0.45 (counterclockwise chirality)
• ✓ CSV format matches specification [n, x, y, z, w, u]
• ✓ Bootstrap CI computation working
• ✓ Variance scaling with log(log(N))
