Do we anticipate others setting up public labs? I suppose it doesn't hurt to
document this even if no other labs are set up.

Ok, happy to keep it all in one place.

We just need to clarify what type(s) of neutrality is in mind. Vendor neutral is probably what people most look for, so I suggest changing it to that - it implies HW neutral I think.

I think just "transparency" is probably the best title then. However, to clarify things, I think it might be good to have a one-line explanation of each bullet point to allow additional clarity. For example:

- reliable: users need to know that any failures are genuine, and not the result of intermittent issues in the test infrastructure
- neutral: the lab should not focus on one HW or SW platform to the exclusion or detriment of others
- transparent: the details of what tests have been run and the result of those tests should be visible to all users.

Yes, I agree they are needed, they just don't fit in the same list as reliability, transparency and neutrality, which are abstract concepts vs coverage reports, trend graphs etc. which are concrete outputs. Therefore I suggest they be put in a separate list on the page, not dropped altogether.

Maybe split it into two levels of bullets:

- compilation
- static analysis
- test case runs, including
  - functional tests
  - performance tests
  - interoperability tests
  - ....

If that doesn't work for you, it's ok to leave as-is. Everyone will understand it, it just reads a little weird to me. 😊

Ah, ok, I understand a little better. To emphasise the triggering rather than what the scan runs on, I suggest "on email reception", or change "run" to "triggered" as in - "triggered on receipt of the patch email, and run on the email itself."
