It does not need to be edited for normal use.\n\n**Process Overview:**\n1.  **Cleans Input:** Removes Markdown fences (```) and trims whitespace.\n2.  **Applies Fixes in Order:**\n    *   Escapes control characters (`\\n`, `\\t`) inside strings.\n    *   Fixes invalid backslashes (e.g., `\\\"` -> `\\\\\"`).\n    *   Removes trailing commas.\n    *   Attempts to fix unescaped quotes within values.\n3.  **Parses:** Tries to parse the cleaned string. If it fails, it looks for a `{...}` or `[...]` block within the text and tries again.\n\n\n**Output:**\n*   The successfully parsed JSON fields.\n*   A `parsing_status` object with detailed logs and debugging info."
