 The submit requirement expression as a string, for example
 `branch:refs/heads/foo and label:verified=+1`.

 True if the submit requirement is fulfilled for the change.

 A list of passing atoms as strings. For the above expression,
 `passing_atoms` can contain ["branch:refs/heads/foo"] if the branch predicate is
 fulfilled for the change.
-|`failing_atoms`|

 A list of failing atoms. This is similar to `passing_atoms` except that it
 contains the list of predicates that are not fulfilled for the change.
