Unit 7 Case Closure

Reopen one bug you solved.

Write the first explanation you believed and the evidence that proved or disproved it.

Then identify the earliest point in the debugging process where you had enough information to stop guessing.

Your response must include at least one exact artifact from the investigation: an exception type, traceback line, variable value, test output, or reproduction step.

Finish with a one-line rule you want to remember the next time a failure looks “random.”
