etl-before-dashboard

Enforces the profile, clean, model and persist order before anything is charted, so a visualization never renders raw ingest. Use when a request asks to chart, plot, dashboard or summarize a CSV, spreadsheet, export or extract, when a bar chart or a monthly total is being built straight from a source file, when values arrive as text, with mixed date formats, comma decimals or lost leading zeros, when the same source arrives a second time as a refreshed or corrected file, when two tables have to be related and the key that joins them has not been established, or when existing code is about to be re-run to rebuild or regenerate a page, a report or a dashboard that somebody will read.
