Corporate signers

• Your company has a Point of Contact who decides which employees are authorized to participate. Ask your POC to be added to the group of authorized contributors. If you don't know who your Point of Contact is, direct the Google project maintainer to go/cla#troubleshoot (Public version).

@googlebot I signed it!

Sorry, I couldn't find a CLA on file under your GitHub username. Please make sure you've signed the CLA and that your commits are edited to have your matching email address (right now they are birdi7@users.noreply.github.com, which I believe is the default for users without a public email address).

@kpreid But I signed it with email egor.birdi7@gmail.com marked Birdi7 as my Github username. The commits are signed with egor.birdi7@gmail.com also

The commit author email address in your two commits is still Birdi7@users.noreply.github.com. The easiest way to fix this — assuming you're using GitHub's web interface — is to make the same edits again, in a different branch than patch-1. Before you do this, make sure the "Keep my email addresses private" option in GitHub's preferences is off.

(On the command line, a rebase -i where you edit each commit by git commit --amend --reset-author and make no other changes would do it, assuming you've set your email address. But I would not recommend doing this if you're not familiar with performing interactive rebases.)
