Data Quality Notes
All cataloged daily ZIP files pass ZIP integrity checks. Some source archives are short, meaning the ZIP is valid but one or more expected five-minute parquet files are absent from the upstream PMData archive.
Use reports/pmdata_btc_5m_coverage_20260215_20260703.md for the monthly coverage table and missing whole-day list. Use catalog/pmdata_missing_windows.csv to mask, exclude, or explicitly patch source-short five-minute windows.
Source Roles
PMData is the primary source for sub-second L2 execution replay and maker/taker fill simulation.
DOME remains the local audit/baseline source for reconstructed 1 Hz windows, source comparison, YES/NO validation, Chainlink/Binance joins, and fallback analysis.
