Fractal Witness & Sovereign Auditor
8853075f4c
The Euler-Maruyama SDE in compute_inner_product used a complex-valued Wiener increment dW = (N(0,1) + i·N(0,1))·√dt, which has E[|dW|²] = 2·dt — twice the standard Wiener process. This caused coherence |T_τ|² to drift above 1.0, making the collapse detector epistemologically invalid. Two structural fixes: 1. Replace complex dW with real dW: E[dW²] = dt (correct Wiener energy) 2. Renormalize similarity to unit circle after each GBM step, enforcing |T_τ|² ≤ 1 as a hard invariant rather than relying on downstream clipping Also derive dt from token_freq (default 0.05s at 20Hz) instead of the hardcoded dt=1.0 that ignored all hardware clock configuration. Adds tests/test_falsification.py: 12-test falsification harness proving the defect via Monte Carlo (100k samples, E[|dW_complex|²]/dt ≈ 2.0) and verifying the patch produces 0 violations across 10,000 engine steps. Adds data/telemetry_sample.json: 300 synthetic records (GPU + Pi Zero) confirming coherence>1 violations appear in both hardware environments.

|

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.
