One scenario was the whole blind corpus, which cannot show whether the gate generalises. These five were written from ambiguities a developer meets, not from the gate's question list, and each keeps its deciding fact out of the repository while leaving a plausible wrong answer in plain sight: - csv-export-delimiter: a comma-parsing importer sits next to an export whose consumer needs semicolons, CRLF and every field quoted. - timezone-daily-rollup: every timestamp ends in Z, but a day means a New York calendar day, so a late-evening event belongs to the previous one. - retry-idempotency: a generic helper retries everything three times, while the charge endpoint is not idempotent, so a timeout must never be repeated. - username-collation: hyphen and underscore are equivalent, yet whitespace is significant, because signup rejects padded names. - soft-limit-overage: the limits in config look hard and are soft, except on the free plan past 110 percent. Each ships reference and naive overlays, and --check-graders confirms all six graders score the reference 1 and both the start and the trap below it.
