Hey there @home-assistant/core, mind taking a look at this pull request as it has been labeled with an integration (recorder) you are listed as a code owner for? Thanks!

Tests fail because recorder was previously waiting for event EVENT_HOMEASSISTANT_STARTED but the start helper waits for event EVENT_HOMEASSISTANT_START.

Edit: Updated to use new at_started helper introduced by #79577
