yetus failed but the summary didn't show anything. Looks like bufcompat had an issue, maybe I need to rebase.

-1 bufcompat 0m 0s /branch-bufcompat-stderr.txt Error running buf. Please check buf stderr files.

cat branch-bufcompat-stderr.txt
register/register.proto:11:8:validate/validate.proto: does not exist

I don't know why the yetus summary doesn't appear, but it is failing due to

where buflint results are:
proto/register/register.proto:11:8:validate/validate.proto: does not exist

Ignoring that known failure, but I don't know if it causes buflint to fail to run hence not check anything else!
