-UniDesk bridge 会把本地 `--json-file`、`--prompt-file`、`--runner-json-file` 或 `--prompt-stdin` materialize 到 G14 `/root/agentrun-v01` 临时文件，然后调用官方 `./scripts/agentrun --manager-url auto`。它不是旧 Code Queue adapter，不双写，也不迁移旧历史。
+日常一次性 JSON、prompt 和 runner JSON 输入优先使用 quoted heredoc/stdin：`--json-stdin`、`--prompt-stdin`、`--runner-json-stdin` 或 `--*-file -`。UniDesk bridge 会把 stdin 直通 G14 `/root/agentrun-v01` 官方 `./scripts/agentrun --manager-url auto` CLI，不先落 dump 文件；`--json-file`、`--prompt-file` 和 `--runner-json-file` 只用于已审阅且可复用的受控文件。它不是旧 Code Queue adapter，不双写，也不迁移旧历史。
 
 AgentRun Queue payload 需要 runner 内使用 UniDesk SSH 透传时，只通过 `executionPolicy.secretScope.toolCredentials[].tool=unidesk-ssh` 请求 `agentrun-v01-tool-unidesk-ssh/UNIDESK_SSH_CLIENT_TOKEN` SecretRef；不要把 token 写入 prompt、payload 或 `transientEnv`。非敏感 endpoint 使用 `UNIDESK_MAIN_SERVER_IP`、`UNIDESK_MAIN_SERVER_HOST` 或 `UNIDESK_FRONTEND_URL`，可由 runner-job `transientEnv` 显式提供；G14 `agentrun-v01` manager 也会在缺省时按受控默认值自动补齐，并在 trace 中只显示 env name/count/hash 与 `valuesPrinted=false`。
