Research direction

No source file, test, or entry point is identified. Reproduce the failure with the listed Nextcloud 25.0.4, Calendar 4.2.4, MariaDB, PHP 8.0, and a large Google Calendar, then trace the calendar import path and compare the imported event count with the source. Done means all events import successfully on a clustered database.
