Week 4 Reflection: What Changed the Program's Behavior?

Choose one Week 4 case where the program produced a different result than expected.

In 5–8 sentences, explain:

• the starting input/state;
• the branch or validation rule that controlled the result;
• the evidence that revealed the mechanism;
• the smallest safe correction;
• what the retest proved; and
• one claim you still cannot make.

Do not write “the code was wrong.” Name the state and mechanism that made it wrong.
