You may need to do manual searches and/or write code to do API calls or similar work. Your workflow should comfortably move between these structures without loss of information. Deliverables • A script (or set of reproducible commands) that collects the raw data from each source. • A cleaned, well-documented dataset in Stata format, ready for analysis. • A short log or README explaining every transformation, validation check, and any assumptions made. Acceptance Criteria 1. All source connections (scraper, database query, API call) must run end-to-end without manual tweaks. 2. Field names, data types, and row counts match the specifications we agree on up front. 3. Missing or anomalous values are flagged and handled according to the documented rules. 4. Final Stata file opens without errors and reproduces the summary statistics we validate together.
