- Зачем:
- форма Trigger DAG требовала заполнить все поля: канонический запуск
«выбрать профиль, остальное пусто» через UI был невозможен (находка F1
ручного HITL); артефакты backfill (data/*.json, 49 МБ) рисковали
попасть в коммит.
- Что:
- пять необязательных Param переведены на Param(None, type=["null",
"string"]) — идиома необязательного поля, проверено по Context7
(Airflow 2.10.5); все места чтения уже None-безопасны (or "").
- контрактный тест дополнен: у необязательных Param есть "null" в type,
у operation/profile — нет.
- .gitignore: правило data/*.json (сиды data/*.jsonl остаются под git);
задача 21 закрыта в .scratch.
- Проверка:
- make test (205 + 31 passed) и make lint — зелёные.
