Reproduce, Reduce, Regress

When debugging a bug, follow this workflow:

1. Reproduce

Goal: Get a failing test that demonstrates the bug using REAL data.

• Copy the EXACT input that triggers the bug (don't paraphrase or simplify yet)
• Use the EXACT types/structs from the failing code
• Verify the test actually fails with the same error message

2. Reduce

Goal: Find the MINIMAL input that still triggers the bug.
