# Code Review: section-05-node-ops-python

**Verdict: PASS with minor observations**

## Plan Adherence: FULL MATCH
Implementation is character-for-character match of the plan's code blocks.

## Issues

### 1. [Medium] No type validation on `operations` parameter
No `isinstance(operations, list)` check. Malformed input (string, int) passes through to bridge.

### 2. [Medium] No validation that each operation dict contains `op` key
Docstring says "Each operation is a dict with an 'op' key" but no check enforced. Missing `op` key forwarded to Godot.

### 3. [Low] Double blank line in test imports
Inconsistent with sibling `test_scene_tree.py` which has single blank line between import groups.

### 4. [Low] Test MAX_OPS shadows implementation constant
Test defines `MAX_OPS = 50` locally rather than importing `MAX_OPERATIONS`. Consistent with sibling pattern but fragile.

### 5. [Low] Missing BridgeError propagation test
Tests cover BridgeConnectionError and BridgeTimeoutError but not BridgeError.

### 6. [Low] No test for non-list input (e.g., operations=None)
No documentation of behavior when None is passed directly (not through MCP wrapper).

## Test Coverage
- 7/7 planned tests pass
- 3 edge cases not covered (BridgeError, non-list input, missing op key)

## Pattern Consistency
Matches sibling `scene_tree.py` pattern exactly. Minor formatting difference in test imports.
