Begin with one submission per row. The project asks for a rate that another analyst can reproduce from a pinned extract, with late outcomes and join multiplicity visible rather than discarded.
Project and required concepts
- Project: audit a receipt-review rate from raw submissions
- Dataset grain and join cardinality: protect the unit of analysis
- Missing data policy: distinguish absence from a measured zero
- Metric denominators and cohorts: make a rate reproducible
- Reproducible analysis snapshots: pin data, code and cutoff together
Completion standard
Submit the runnable analysis, its input and version manifest, the outcome counts, failure-case checks and a short decision note. Keep the final evaluation partition separate from development choices.
