Fourth and final volume. Formally identifies six structural patterns from the full set of positions across the first three volumes: (1) strong expansion inertia of the institutional layer in the absence of explicit contraction mechanisms; (2) the relational layer as colonization's transmission medium and as buffer against absolute institutional dominance; (3) conditions and fragility of individual-layer emergence; (4) the gradual drift from cultivation to colonization; (5) structural symmetry and complementarity of the three civilizational lines; (6) autocatalytic acceleration of the chisel-construct cycle. Includes a panoramic coordinate table, civilization-history verification of Paper 3's functional asymmetry thesis, a complete self-reflexivity statement, and open questions (India, Islam, America, reformed capitalism, post-WWII, AI as institutional layer).
