Coordination Unsatisfiability: Phase Transitions in Institutional Rule Systems

We demonstrate that institutional rule systems undergo sharp phase transitions from satisfiable to unsatisfiable states at critical constraint densities, following the same mathematics as random k-SAT problems.

Key findings:

1. **CUTT Theorem**: For rule systems with m constraints over n effective decision variables, a phase transition occurs at α_c = m/n ≈ 4.27 (for 3-SAT equivalent rules).

2. **Unified Impossibility Family**: CAP theorem, Arrow's impossibility, Byzantine bounds, and FLP impossibility are all instances of the same constraint satisfaction phase transition.

3. **Bureaucratic Bloat Paradox**: Adding personnel without autonomous decision capacity contributes zero to n_eff. Organizations stay in UNSAT regime, just more expensively.

4. **Scale Invariance**: α_eff is invariant under arbitrary subdivision. You cannot "org-chart your way out" of a phase transition.
