== Validation ==
The computation has been analytically verified against known closed-form test cases:
* '''Uniaxial traction along gauge A''': εA = ε₀, εB = −ν·ε₀/... (45° gauge), εC = −ν·ε₀ → σ₁ = E·ε₀, θ = 0 ✓
* '''Pure shear''': symmetric strain state → σ₁ = −σ₂, θ = ±45° ✓
* '''Hydrostatic''': εA = εB = εC → σ₁ = σ₂ = E·ε/(1−ν), θ = undefined (isotropic) ✓
* '''Real signal''' (steel structure, 12 800 Hz, 5 s): relative precision < 1.5 × 10⁻⁷ (float64 round-off only) ✓
