There was a problem hiding this comment.
Happy with this.
- CI is passing.
- DCA shows 7088 results have been removed - in line with the intent of this PR.
- I did a small local + MRVA run and the lost results all look as expected (i.e. static variables) while the remaining results are not.
- I don't believe the query is in any standard suite.
