  "objective": "A CLI grades a SQL file against an original drill on a pinned mysql:8.0.33 container by exact judge-style output match, with 12 drills ordered by priority.",
  "acceptance_criteria": [
    "start/stop/list/show/check work; check exits 0 pass, 1 mismatch (line diff), 2 SQL or engine error",
    "Normaliser and diff are unit-tested without Docker; package coverage is 100% branch",
    "Every drill's reference solution (tests/solutions only) reproduces expected.txt on live MySQL; those tests skip when the container is down",
    "show and check never print reference SQL"
