"""Unit tests for Msg.append_event – event-stream-to-Msg accumulation.
The test drives a single Msg object through a full, realistic streaming

Coverage
--------
* TextBlock : start / delta (×2) / end
* ThinkingBlock : start / delta (×2) / end
* DataBlock (base-64) : start / delta (×2) / end
* ToolCallBlock streaming : start / delta (×2) / end
* RequireUserConfirmEvent → ASKING state
* UserConfirmResultEvent (confirmed=True) → ALLOWED state
* UserConfirmResultEvent (confirmed=False) → FINISHED state
* ToolResultBlock text output : start / text-delta (×2) / end (SUCCESS)
* RequireExternalExecutionEvent → SUBMITTED state
* ExternalExecutionResultEvent → ToolResultBlock appended directly
* ToolResultBlock data output : base-64 delta + URL delta / end (ERROR)
* ModelCallEndEvent (×2) → usage initialized then accumulated
* ReplyEndEvent → finished_at stamped
* Wrong reply_id → event silently skipped
* Missing block → warning, no crash
