Все nullable jsonb-колонки ORM (audit_event.before_value/after_value, ex_snapshot_item.payload, recognition_job.group_schema/metrics, osv_entry.original_values) объявлены через nullable_jsonb() = JSONB(none_as_null=True): Python None сохраняется как SQL NULL, IS NULL находит строку. DDL не меняется; сверка с DBML и миграции зелёные. Обходы для не-объекта в metrics (CASE по jsonb_typeof в публикаторе, merge_metrics в inbox) оставлены: строки до исправления и сырой SQL могут содержать jsonb null. Тесты: SQL NULL после AuditService.record без before/after, metrics фабрики None -> SQL NULL, повтор публикации и слияние метрик для SQL NULL и jsonb null, перечень колонок с флагом.

"""Outbox-публикатор и вахтёр сроков `recognition_job` (spec recognition-job-exchange: «Outbox публикует задания из
|
||
`queued`», «Запрос без ack публикуется повторно, затем — `dlq`», «Таймаут ожидания результата»; design D-6).
|
||
|
||
Интеграционные тесты работают против реального PostgreSQL (БД сессии pytest) и NATS из `.env.test`. Публикатор и
|
||
вахтёр ведут собственные транзакции, поэтому данные фиксируются реально (`CommittedJobs`) и удаляются в teardown.
|
||
Subject'ы запросов общие (`recognition.*.request`): тестовый подписчик фильтрует сообщения по `job_id` своих заданий.
|
||
Время в тестах повторов — инжектируемые часы `now`, без реальных ожиданий таймаутов.
