CONTENTS

SAMPLE METHOD
Rows are selected at deterministic, evenly spaced positions across the
versioned full release. This exposes the real schema and representative
historical coverage without claiming to be a statistically random sample.

SECURITY
This archive contains data and documentation only: CSV, JSON and TXT.
It contains no executable files, scripts, macros or spreadsheet workbooks.
The build fails if a sampled cell looks like a spreadsheet formula. Verify
file integrity with SHA-256 before use.

LIMITATIONS
The sample is provided for evaluation and research. Null values are expected.
Post-transaction return fields are descriptive and do not establish causation
or predict future performance. Review the full methodology and license at:
