Stage 4 Article Contract Fixtures

End-to-end tests fail at stage 4 transitions when required artifacts are missing. You need both discussion-summary.md and article-contract.md present before advancing to stage 5 to prevent guard errors and flaky test runs.

To generate stage 4 article contract fixtures, use helper patterns that auto-write discussion-summary.md and article-contract.md during test suite stage transitions, providing deterministic fixture generation and guard logic integration.

A stage 4 article contract fixture is a deterministic test artifact ensuring discussion-summary.md and article-contract.md exist before an article advances from stage 4 to stage 5 in lifecycle tests spanning stages 1 through 7.

Yes, you can use a standard article-contract.md template to enforce consistency. The fixtures provide a standard template that guarantees both required artifacts are generated before stage advancement occurs.

Yes, dual-artifact presence is enforced when advancing from stage 4 to stage 5. Both discussion-summary.md and article-contract.md must be created and verified by the fixture guard logic to avoid errors.
