THF Technical Bulletin 2026.01: Deterministic Falsifiability Targets for TUSC Mechanical Cosmology

This Technical Bulletin establishes the deterministic falsifiability targets for the TUSC (The Universal Source Code) framework. By modeling the vacuum as a Satiated Substrate (Plenum), TUSC provides specific mechanical indices for the Hubble Constant (H_0 = 71.403) and the Universal Ringdown Floor (\eta \approx 101.859 \text{ Hz}). This document serves as a timestamped forensic record for future verification against JWST, LIGO, and ELT datasets.
