Organic-support layers became most valuable when supply loops tightened and replacement had to be coaxed from local conditions.

Distance and scarcity slow the social maturation of machine branches even when their technical competence rises quickly.

Biohybrid adaptation spread widely, but some branches judged pure synthetic continuity to be the stronger long-term path.

Near-sun operations forced machine branches to treat thermal regulation as a civic condition rather than a background system.
