Seeds the pipeline with the REAL #192 CONVERGED case-mismatch payload: the
safety-net convergence step exported Python-cased True/False from
json.load while the steps compared env.CONVERGED == 'false' — both
conditionals unreachable (discharged on the release-safety-net branch,
public in PR #211's diff). Captured via the pipeline itself
(--class env-case-mismatch --source ci, 0 redactions — the payload is
already public and credential-free). The generated regression test asserts
the boolean-export checker still FLAGS the recorded payload
(checker_expectation: flags), so a recurrence of the class fails CI.
Manifest gains checker_expectation: capture records whether the class's
checker raises on the payload ('flags' — the raise IS the recurrence alarm)
or must stay quiet ('passes'); the generated tests enforce the recorded
expectation, so a checker that stops catching its recorded defect rots the
suite red.
Docs: bugfix-contract §10 gains the operational capture step + explicit
trivial-bug exemption list; README dev section points at the pipeline;
tests/fixtures/production/README.md documents the flow.
Henxels: capture_failure.py required in scripts/; production fixtures
governed (manifest.json + README.md required); payload.json and
manifest.json travel together (changed_with both directions, verified to
bite on a payload-only staged change).
