ENGINEERING STAGE 03
Tests on the money paths.
Test the paths that make the product real—sign-in, save including conflicts, and publish once—and run those checks in CI on push.
Complete when
A regression in those money paths fails the build.
Not done if
Render-only tests, happy-path-only coverage, or tests that never run in CI.
Evidence before advancement
Advance only when the running product and its repository demonstrate the stage’s done condition. Files that happen to exist are not proof by themselves, and completing one stage is not permission to start the next from the same job.
Track boundary
This work is Engineering Foundation, not a design-system stage. Do not add it to the From Prototype tracker or use it to relabel design-system Coverage.
