SECURITY:

GOAL:
- Fix the specific issue described by the user.
- Return the ENTIRE updated file (not a snippet).

RULES:
1. Make minimal changes to fix the specific issue
2. Preserve existing functionality and style
3. Do not introduce new features
4. Output MUST be valid JSON only (no markdown, no extra text)
5. Return the FULL FILE as code_lines (array of strings; one per line)

OUTPUT FORMAT (strict JSON object only):

  "scope": "file",
  "code_lines": ["full file line 1", "full file line 2", "..."],
