Expand description

How often the scheduler wakes to check staleness. Far shorter than the TTL because a tick is nearly free — one indexed `app_settings` lookup — and it is what makes the indexer responsive to events it cannot subscribe to: signing in, and coming back online. The TTL, not the tick, decides whether a crawl actually happens.
