+Created user
+- username: openclaw
+- fullname: OpenClaw
+- email: openclaw@git.an2.io
+
+SSH key
+- private key: /home/user/.ssh/id_gitea_openclaw
+- public key: /home/user/.ssh/id_gitea_openclaw.pub

+- port: 222
+- user: git
+- identity: /home/user/.ssh/id_gitea_openclaw

+- ssh -T gitea
+- result: authenticated successfully as openclaw
+
+Access token
+- created for user: openclaw
+- token name: openclaw-bootstrap
+- scopes: all
+- token value was generated during bootstrap and should be stored securely if you want API repo management later
+
+Recommended usage
+- clone/pull/push via SSH
+- repo create/delete via Gitea API token
+
+Example remote forms
+- ssh://git@git.an2.io:222/openclaw/repo.git
+- gitea:openclaw/repo.git   (via SSH config alias if your git tooling uses it explicitly)
+
+Suggested next steps
+1. Store the generated Gitea token somewhere safe for future API use
+2. Create a first test repo under openclaw
+3. Verify clone, commit, and push with the SSH identity
