- новый файл: имя → содержимое текстом (```-обёртка снимается) или документом - новая папка (виртуальная, пока в ней нет файлов), замена с diff +N/−M, удаление - валидация: имя, ≤ 100 КБ, UTF-8, без NUL; .py — ast.parse с выбором «исправить / всё равно»; .sourcecraft/, .tgit/, ruff.toml из бота не меняются - DraftService: черновик в БД, 24 ч, ≤ 50 изменений; удаление нового файла убирает его из черновика - дерево показывает черновик поверх репозитория: 🆕 / ✏️ / 🗑, размер — как будет после пуша - экран черновика (A/M/D) с «↩️ убрать» Refs #26 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
