Treat production, staging, development, preview and local work as distinct installation contexts.
One installation can have several environments.
Key now distinguishes production from staging, development, preview and local work. Classification informs Key's canonical activation policy; staging, development, preview and local environments stay distinct from production capacity.
Production capacity
Only a production classification is marked as a production-capacity candidate. The final commercial rule still belongs to the license policy.
