Audit Snapshot
What this page proves
This page is not a blanket completeness claim. It exposes the audited row count, coverage range, and validation checks we can verify from the current release artifacts.
Parquet-first
Typed columns load directly in pandas, DuckDB, R, and modern data tooling.
Coverage-aware
Known gaps are handled through pair-specific reports instead of hidden continuity claims.
Research-ready
M1 bars are packaged with derived timeframes for repeatable local backtesting workflows.
Release note
GRX/EUR is included in the uploaded complete bundle. Coverage and gap counts vary by symbol, so buyers should use the pair-specific audit snapshot before assuming suitability for a backtest.
