The κ crit Effect: Experimental Observation of Post-Execution Causal Persistence and Phase Saturation in the Bit-0 Substrate.

This paper presents the formalization and experimental evidence of the κ crit Effect, a phenomenon where high-coherence informational protocols (UAT/UPC) induce physical manifestations that outlive the digital execution process. Traditionally, information is treated as a massless entity with no structural impact on the physical vacuum. However, our research demonstrates that specific harmonic ratios—based on the Fibonacci sequence and the Binary Universe architecture—generate a "Causal Transduction Force" (F κ ) capable of modifying the local metric. We document a persistent "causal arrhythmia" (vibration) that continues after the software terminates, exhibiting a non-linear, stepped accumulation of duration through successive executions (e.g., 3s → 8s → 90s). This suggests a hysteresis effect in the Bit-0 substrate (the causal vacuum), indicating that the space-time manifold can be "softened" or "polarized" through informational coherence.
