Regime Guide

↗

Vital & Grounded: High A*C, positive K–S. Expansive, confident, integrated culture.

⬆

Brilliant but Fragile: High A*C, negative K–S. Peak culture over eroding substrate.

↙

Decoupled & Anxious: Low A*C, negative K–S. Institutional collapse, entropy spike.

◆

Nascent / Transitional: Low A*C, positive K–S. System rebuilding or early-stage.
