Ah, oh well, nevermind.

It's probably more a long-term thing than an immediate fix, but...
The checks API is designed to integrate reporting of CI/testing results
into Patchwork. It allows - through a REST API - an arbitrary process
(like your checking) to report success/warning/failure against a
patch. In your case you could report success = patch prevents bug, and
failure = bug still exists with patch. It's still slightly a
work-in-progress: at the moment you need an API key from a maintainer to
post checks. But it does look pretty in the web frontend:
e.g. - and the number of
successful/warning/failed tests shows up on the patch list page.

There's currently only one project (that I know of) out there that uses
the checks API - Snowpatch:

If, at any point in the future, you want to explore this, let me know as
I'd be *very* happy to help with the implementation and if needed push
features into Patchwork that make it easier/better.

In immediate practical terms, that might be the easiest. They all come
from the same email address, right?
