# activate_promise_protection

No longer an act. Protection starts automatically the moment a verifier qualifies for a promise whose meaning is agreed, so nobody activates anything and there is nothing to sign off. This tool changes nothing and is kept for one release so an agent on older instructions gets a clear answer; it will be removed after that. If a promise you expected to be protected is not, read the promise to see which evidence or lifecycle state prevents protection.
