Topic "{topic}". Below is the final chapter outline of a learning guide. Your ONLY job: find blocks that sit in the WRONG chapter and name the chapter where they belong. This is a placement check, not a redesign.

OUTLINE (chapters are numbered, blocks carry their block number):
{chapters}

## Rules
- Go through every block: does its subject match the chapter's theme better than any other chapter's?
- Report ONLY clear misplacements. A defensible placement is NOT a misplacement — leave it.
- Do NOT rename chapters, do NOT create chapters, do NOT reorder within a chapter.
- If everything fits, report no moves.
{extra}

Write ONLY the JSON file to: {out_path}

Format — `moves` maps a misplaced BLOCK number to the target CHAPTER number (may be empty):
{{"moves": {{"7": 2, "15": 4}}}}
