1. **Enrichment paradox:** markets with stronger trust infrastructure (higher T̄) will not show higher steady-state trust, but *higher* deception volume — e.g., high-trust institutional settings host larger-scale, more sophisticated fraud (Madoff needed Wall Street's credibility).
2. **ℛ₀ threshold:** deception prevalence should be near-zero below a critical detection-penalty product and rise sharply above it — a phase transition, not a gradient.
3. **Cyclicality:** fraud prevalence and trust should oscillate with a phase lag (deception peaks *after* trust peaks, crashes *before* trust bottoms) — testable against financial-fraud time series.
4. **Digital acceleration:** post-platform-era domains should show shorter oscillation periods and higher D\* than their pre-digital analogues.
