| 16 | // Push protection also covers commits made without git (web editor, REST, MCP). |
| 17 | // Repository-limited tokens can't mint wider ones; settings changed through the |
| 18 | // API are audited; readers' labels and assignees are dropped. Repository |
| 19 | // transfers keep a repository's data and leave redirects (web, REST, git, MCP, |
| 20 | // images) that only readers can follow; emptied organizations can be deleted. |

| 22 | // merge queue) where a person allowed it and a required check gates it, never by bypass. |
