 * agent 协作：人类签发写入授权（POST /v3/agent-grants），模型凭模型 token + X-Agent-Grant 代写。
 *
 * 完整代写链路需要一个归测试账号所有的 AI 模型：在 config.local.php 的
 * fixtures.agent_model 填它的 uid，没填则 SKIP。模型 token 目前只有 v2 端点能取
 * （GET /v2/ai-model-token/{uid}），这里只把它当准备步骤用。
 * 权限矩阵（别的 channel / book、撤销、伪造、v2 token 冒充）由 api-v13 的 AgentGrantV3Test 覆盖。
