Notebook 01 · ~30 min · Skill: fault isolation

Take ten questions the baseline gets wrong. For each, run the fault-isolation tree and record the owning stage. Produce the distribution.

Acceptance criteria

• A table of ten rows: qid, owning stage, the trace evidence that decided it
• The distribution as a chart
• One paragraph: given this distribution, what would you do in week one, and what would you explicitly not do?

Stretch: the tree's default branch fires on some cases. Explain why, and say whether the pipeline or the rubric is at fault.
