Настройки инстанса и журнал почтовых рассылок:
|
|
- `instance_settings` — key-value настройки инстанса (JSONB), бутстрап из
|
|
`config/plugins.yaml` в lifespan backend (`services/instance_settings.py`);
|
|
- `email_deliveries` — идемпотентность рассылки саммари (уникальный частичный
|
|
индекс по `(session_id, recipient_email)` при `kind='summary'`) и журнал
|
|
приглашений (`kind='invitation'`, без unique — переслать обновление
|
|
расписания обязано дублировать письмо);
|
|
- `conferences.summary_recipients` — переопределение рассылки для конкретной
|
|
конференции (`NULL` = дефолт инстанса), `conferences.ics_sequence` —
|
|
счётчик изменений расписания для VEVENT `SEQUENCE`;
|
|
- `users.is_blocked` — блокировка администратором, проверяется немедленно в
|
|
`api/deps.py::_user_from_token`.
