## Why Applications need to deliver content from other agents, tools, or services with tool-level authority, without treating it as user input or granting authorization. ## What changed - Export `ExternalMessage` for sync and async `run(...)` and `turn(...)`, accepting text or structured content with a tool name and optional namespace. Send it through `toolOutput` and require CLI 0.151.0 or newer. - Support starting a turn or joining an active regular turn while preserving external content as function output in history. Keep external messages separate from user-input lists and `steer(...)`. - Give turn handles independent subscriptions, replaying completed items and latest usage to joining handles. Release consumed transient events and clean up subscriptions on closure, failure, or cancellation. - Document the authority boundary and add sync and async examples. ## Testing Add coverage for wire representations, input validation, runtime compatibility, tool authority across resume, active-turn joins, and tool-output truncation. Add subscription tests for replay, concurrent consumers, early completion, cancellation, and cleanup. GitOrigin-RevId: 6106327085fd9c4bd11b71e20b3d8e74738b8bb5
