Ally / Partner / Combine

Gain capability, reach, or resilience by combining forces with others WITHOUT acquiring them or being acquired: alliances, joint ventures, ecosystems, and cooperation with competitors.

Why proposed: Proposed extra class. The taxonomy already covers buying a company (regroup.acquisition-integration) and being bought (transition.outright-sale), but has no home for staying independent while joining forces. Alliances, JVs, platforms/ecosystems, and coopetition are a distinct intent with their own substantial literature.
