# Section 01 Code Review: set_main_scene

## Summary
Clean, minimal implementation. 3 additions:
1. Dispatch table entry for `"set_main_scene"`
2. `_set_main_scene_internal()` helper (reusable by _handle_run in section-02)
3. `_handle_set_main_scene()` handler with path normalization and error handling

## Findings
- **No issues found.** The implementation follows all existing patterns (send_response, _send_error, params extraction with str() cast).
- Path normalization (prepend `res://`) matches the pattern used elsewhere.
- `_set_main_scene_internal` is correctly separated for reuse by section-02.

## Decision
No fixes needed. Ready to commit.
