# Code Review Interview: Section 11 — Input Mouse Motion

## Triage Decisions

| # | Finding | Severity | Decision | Rationale |
|---|---------|----------|----------|-----------|
| 1 | Missing Python-side validation | High | Let go | input_sim.py is a pure passthrough — consistent with all other command types. GDScript handles defaults. |
| 2 | Missing validation error test | Medium | Let go | No validation to test (see #1). |
| 3 | Missing mixed commands test | Medium | **Auto-fix** | Added test_mouse_motion_mixed_commands verifying action+mouse_motion+wait interleaving. |
| 4 | Missing TOOL_DESCRIPTION test | Low | Let go | String assertion tests are fragile and low value. |
| 5 | No velocity field | Low-Med | Let go | Most FPS implementations read event.relative, not velocity. |
| 6 | Silent zero-default | Low-Med | Let go | Consistent with GDScript handler patterns for other command types. |
| 7 | Mock-only tests | Obs | Let go | Consistent with entire test file. |

## Auto-fixes Applied

1. Added `test_mouse_motion_mixed_commands` test verifying sequential execution of action + mouse_motion + wait commands.

## Result

All 13 tests passing.
