Points: 200 · Type: project · Evidence: objective (verify.py)
The final challenge of the Data Analysis path. Everything the path taught —
loading messy exports, cleaning with counted removals, summarizing with
checkable numbers, reporting with traceable metrics — applied end to end
on capstone/dataset/orders.csv.
Work in paths/data-analysis/capstone/. The contract is TASK.md
(TASK_cn.md for 中文): your pipeline writes out/results.json with the
specified keys and out/report.md with the required sections, then
python verify.py checks the numbers against ground truth and prints the
capstone claim code.
Use your agent for the boring parts — parsing, aggregation, rendering — and keep the contract in front of it. The solution folder exists for maintainer review; do not copy it for your first attempt.
python verify.py exits 0 → claim code recorded against the Data
Analysis path badge (200 points). Self-reported evidence, never a
certificate.
