# Code Review — TP-003 Step 4

## Summary

APPROVE — the Step 4 protocol tests now exercise the icuvisor `Server.Run` path with injected transports, cover initialize/list/call behavior without Claude, and include raw malformed MCP request coverage plus sanitized handler-error assertions.

## Findings
