# 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.
