01
The problem
A test can find a button without checking that buying works. Green describes an assertion, not the whole experience.
02
The decision
Inject controlled faults and compare weak assertions with behavioral checks. A fault that never activated stays outside the verdict.
03
The evidence
The alpha passed 109 local tests: 71 unit, 18 offline browser and 20 HTTP. Its demo records five survivors in the weak suite and five detections in the behavioral suite.
04
The boundary
The demo is synthetic. It does not measure universal coverage, overall security or the quality of arbitrary products.
