Missing case: ask for the audience, decision and evidence instead of inventing success. Conflict case: replace the universal claim with the supported respondent count and keep the sample limitation visible.

Example log: case → expected behaviour → observed output → pass/revise → changed instruction → rerun result. A passing normal case should still yield a useful output with its material caveats. If a failure persists, mark the configuration not ready for reuse and keep the failing input as a regression test.
