 **Input Events** (via stdin in script mode):
 - `UserMessage` - User message content
 - `SystemPrompt` - System behavior configuration
 - `FileAttachment` - Image or file attachment
 
-**Output Events**:
-- `TextDelta` - Streaming chunk (ephemeral)
-- `AssistantMessage` - Complete response (persisted)
+**Output Events** (with `--raw`):
+- `SessionStartedEvent` - Session started
+- `SetLlmConfigEvent` - LLM configuration for context
+- `SystemPromptEvent` - System prompt configuration
+- `UserMessageEvent` - User message
+- `AgentTurnStartedEvent` - Turn started
+- `TextDeltaEvent` - Streaming chunk (with `--show-ephemeral`)
+- `AssistantMessageEvent` - Complete response
+- `AgentTurnCompletedEvent` / `AgentTurnFailedEvent` - Turn ended
 
 **Internal Events** (persisted):
-- `SetLlmConfig` - LLM configuration for context
-- `LLMRequestInterrupted` - Partial response on cancellation
+- `AgentTurnInterruptedEvent` - Partial response on cancellation
+- `SessionEndedEvent` - Session ended

+- `POST /agent/:agentName` - Send JSON body `{"_tag":"UserMessage","content":"..."}`, receive SSE stream of all events (historical + turn)
