**(c) Capture as a coupling from D to μ.**
The most cynical and arguably most realistic: let deceivers *invest in weakening enforcement*, so atrophy rate μ = μ(D) **increases** with entrenched deception (regulatory capture, lobbying, revolving doors). This creates a *positive* feedback fighting the negative one — and can produce **bistability**: a "clean" low-deception basin and a "captured" high-deception basin, with hysteresis. The market can get *trapped* in a captured equilibrium and require a large shock to escape. This is probably your single most compelling and citable result — it formalizes state capture as an attractor.
