* [x] ParserCache (stable revision): new row added in {T304480}
* [x] RevisionOutputCache (older revisions)
* [] Parser load
* Can't find anything! But duplicate parse logs cover the most important part of this.

Healthy: no impact on load
Unhealthy: decrease in RevisionOutputCache cache hit rate; increase in parser load; any stable cache miss
We'll want to watch the stable cache long-term.
