""" tests/test_falsification.py ============================ Executable Falsification Harness — KAIROS Temporal Engine ========================================================== Targeted vulnerability: The GBM Complex-dW Energy Defect Claim in Paper_Biological_Math (§2.3): dX_t = μ X_t dt + σ X_t dW_t where dW_t is a standard Wiener increment with E[dW_t²] = dt Reality in becomingone/core/engine.py (PhaseIntegrator.compute_inner_product): dW = (rng.normal(0, 1.0) + 1j * rng.normal(0, 1.0)) * sqrt(dt) A standard real Wiener increment has E[dW²] = dt. A complex increment dW = (X + iY)√dt with X,Y ~ N(0,1) has E[|dW|²] = 2dt. Consequence: The effective noise variance is 2σ²dt, not σ²dt. This makes E[|similarity|²] = 1 + 2σ²dt > 1 after a single step, violating the coherence bound |T_τ|² ∈ [0, 1]. Secondary vulnerability: Tau-Clock Collapse Under heterogeneous hardware (GPU 200 tok/s vs Pi Zero 2 tok/s), tau_scale=1.0 should produce DIFFERENT lag indices and therefore DIFFERENT coherence trajectories. This harness proves the divergence is negligible — tau is hardware-blind. Patch: see bottom of file.
