## Push fails when repo created by different API user than SSH alias

**Symptom:** `git push` to a new repo fails with "User permission denied for writing."
**Cause:** Repo was created via API using `ai_admin` token, but SSH alias authenticates as `cluster-administrator` who has no access.
**Fix:** After creating a repo via API, add the SSH-authenticating user as collaborator: `PUT /api/v1/repos/<org>/<repo>/collaborators/<ssh-user>` with admin permission. Do this before attempting to push.
