Microservices integration across Hsinchu product pods and Chupei platform groups breaks when producers change payloads without a shared check. Consumer-driven contract tests turn that risk into a pipeline signal instead of a production surprise.
Start with the hottest consumers, not every endpoint. Version the contract explicitly and keep provider verification in CI so deprecations are visible before they ship. Remote teammates should see the same failure artifacts as people in the room—screenshots in chat are not a verification strategy.
The goal is boring coordination: everyone knows which fields are mutable this sprint and which stay frozen until the next contract workshop.
