Saturn profiled 7 rows across 1 columns. The stats below are deterministic and machine-readable; the prose is a language-model interpretation of those stats (opt-in, added after the fact, never sees raw rows).

])This is the 'Read Me' sheet from the USDA Food Access Research Atlas 2019 download, not an analytical dataset. It contains just 7 rows in a single column of free-text notes describing the workbook's contents, source URL, and release history. Each row is unique, so there is nothing to aggregate or model here. Treat this sheet as documentation and pivot to the sibling sheets (the variable lookup and the main data table) for actual analysis.

This isn't a real data column — it's the README/preamble lines from the Food Access Research Atlas download, captured as 7 unique rows including 'This file contains multiple spreadsheets:', a USDA URL, and 'Initial release: April 2021'. Each of the 7 values appears exactly once (entropy_ratio 1.0), confirming it's documentation text rather than observations. The column header itself ('Notes about the Food Access Research Atlas download data:') is a sentence, which is a strong tell that the spreadsheet was loaded with the wrong header row.
Treatment: Drop this column and reload the source file skipping the preamble rows so the true header is used.
