What this page is for
Use [/nations/[id]/progression](/nations/[id]/progression) to answer three questions quickly:
- Which gate is currently blocking my next era?
- Which project should I start next?
- Has the active project builder been started with labor?
1) Reading gates (PASS vs BLOCKED)
Progression gates are AND-gated. Your next era unlocks only when all required lanes pass together:
- Infrastructure gate
- Technology gate
- Era project gate
2) Reading projects (status + progress)
Each project line tells you both state and completion progress:
Not startedActiveCompleteCancelled
Use progress as a planning signal for what to start next.
3) Reading labor status
Project funding is an upfront labor start action.
Key fields to interpret:
- Current labor and labor max
- Active project's labor start cost
- Whether the builder is started
Suggested decision loop per tick window
- Check which gate is
BLOCKED. - Start the next eligible project if one is not active.
- Start the active project builder with labor.
- Recheck status after tick resolution in Outcomes.
Common blockers and fixes
PROJECT_PREREQ_NOT_MET: complete prerequisite project first.PROJECT_NOT_ACTIVE: start the project before funding it.PROJECT_ALREADY_FUNDED: builder is already started.INSUFFICIENT_LABOR: wait for labor regen and retry.
