[python-committers] What is github trying to tell me?

https://github.com/python/cpython/pull/28163 has two messages of:

@ericvsmith <https://github.com/ericvsmith>: Status check is done, and it's a failure ❌ .

Followed by the merge messages, followed by:

@ericvsmith <https://github.com/ericvsmith>: Status check is done, and it's a success ✅ .

What do the failure messages mean? Is it because I didn't wait for the checks to complete before merging?

(It's a documentation only change that I previously committed to main without incident, so I didn't feel the need to wait for all of the checks to run before merging.)

Thanks for any insight.

Eric
