What a green suite actually proves
Two independent builds, thousands of tests passing in each: and the same four adversarial review lenses failed both. A green suite means the tests agree with the code, not that the design is right.
Two separate implementations of the same feature both came back green, thousands of tests passing, and both failed the same four adversarial review lenses. Identical failure classes across independent builds point at the design, not the code. So instead of a third rework, the spec was split: the achievable half shipped, and the rest was recorded as unachievable as specified.
