WalkthroughФормальная сборка использует контролируемые вызовы Git и расширенную проверку чистоты checkout. Сборка сверяет commit и хеши исходников до начала работы и повторно проверяет состояние перед записью receipt. Тесты проверяют изменения, которые Git status или флаги индекса могут скрыть.

Priority: ➖ Normal Estimated code review effort: 3 (Moderate) | ~25 minutes Change: Bug fix Merge Risk: ⚪ Minimal · up to The change makes the formal core assembler refuse to issue a receipt unless the checkout is clean and matches the exact commit and source digests. The reported bypasses are covered by new tests. No remaining merge-blocking issue is evident from the supplied review, although the tests were not run in this review. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

- Line 444: Update Git subprocess environment handling in checkout_snapshot()
and assert_snapshot() to remove repository-overriding variables such as GIT_DIR
and GIT_WORK_TREE whenever Git runs with a specified cwd, so repository state
and file hashes are checked against the same local checkout.

- Around line 245-249: Update checkout_is_clean and its git_checkout_output
calls to ensure local core.fsmonitor cannot hide modified tracked files during
the cleanliness check. Preserve fail-closed behavior on Git versions that
interpret the disabling setting as a hook path, or use a safe alternative on
those versions.

Задача
Сборщик formal core мог выпустить receipt с вымышленными
checkout_commit,source_commitиverified_source_sha256. Локальныйfsmonitor, игнорируемый файл Core или tracked symlink также могли скрыть расхождение между Git commit и фактически прочитанным источником.Исправление
fsmonitor.Проверки
fsmonitor, игнорируемый файл Core, tracked symlink, повреждённый Git object и изменение во время сборки.3e9e12990794172412bb6179e651e83b22faed77в закреплённом Linux Docker окружении: 23/23 verifier tests и 2/2 проверки LF artifact matrix;git diff --checkчистый.2fb72a5. Локальный Kani 0.68 в доступном образе отсутствует; формальное доказательство нового Python verifier не заявляется.Граница
Receipt удостоверяет источник локального checkout сборщика. CI отдельно связывает фрагменты с точным
github.shaи попыткой workflow. Локальные проверки, удалённый CI и review относятся к разным гейтам; состояние последних видно в PR для текущего head.При регрессии выпуск formal receipt нужно остановить, откатить изменение и заново пройти formal gate на точном SHA.
