Pass the expansion readiness check
- Name the resource, contract, or objective that requires expansion.
- Confirm the current settlement can spare workers and construction inputs.
- Plan storage and transport at both ends of the route.
- Protect essential local needs before exporting goods.
- Open one route and measure whether it solves the original shortage.
Use trade as a controlled input
- Identify the exact missing good before accepting or creating a route.
- Check the current contract or trade terms rather than copying an old value.
- Keep storage headroom at the receiving settlement.
- Review whether the route creates a new labor or transport bottleneck.
Stop cascading failures
If needs, staffing, storage, and shipping all fall at once, pause expansion. Restore one stable production and logistics loop before adding another island or route.
