 - Output goes to `stdout` by default; use `--out` to write a file.
 - The renderer preserves markdown-heavy comment bodies safely by adjusting code fences when needed.
+- Both `Comment` and `Reply` include their directly associated file path and line number (when provided by the API).

 - 默认输出到 `stdout`；仅在指定 `--out` 时写入文件。
 - 当评论正文本身包含 Markdown / 代码块时，渲染器会自动处理 fence，避免破坏整体结构。
+- `Comment` 和 `Reply` 都会显示各自直接关联的文件路径与行号（若 API 提供）。
