Consider a coding agent asked to add a promotion type to a shared discount service. The task looks narrow. The agent changes one API endpoint, adds focused tests, and returns a clean diff. Everything in the assigned task can be correct while the release still changes renewal pricing, invoice totals, account entitlements, or a reporting job that depends on the same service. That is the core problem with reviewing agent-generated code only at the task boundary. The implementation
