Upload Checklist

• Confirm each upstream source permits personal-use storage and the planned Hugging Face visibility.
• Keep the repository private unless redistribution rights are confirmed.
• Copy only the datasets listed as pending_copy or approved after review.
• Preserve source, exchange, market type, symbol, interval, timezone, and date range.
• Run duplicate-key, missing-bar, timestamp, schema, and file-hash checks after copying.
• Add the final quality reports under quality_reports/.
• Complete the Hugging Face Dataset Card with license and provenance metadata.
• Verify that no API credentials, personal data, raw article text, virtualenv files, or code artifacts are included.

Canonical key

For market bars, the expected logical key is:

source + exchange + market_type + symbol + interval + timestamp_utc

Do not merge records across exchanges or intervals without retaining those dimensions.
