Before changing Mission architecture, answer yes to these checks:

• Does the behavior have an explicit owner?
• Is domain behavior inside an Entity, policy, repository, adapter, orchestrator, or strict contract-bearing object?
• Does the surface remain a surface?
• Are provider details isolated behind adapters?
• Are persisted and accepted shapes validated by schemas?
• Does the change follow current ADRs or record a new decision?
• Can the change be verified deterministically?

If the answer is no, the design is not ready.
