- Repeat snapshots taken seconds apart are dropped, so
hoursTrending24h no longer double-counts.
- History rows now include
searchUrl and no longer carry cross-location fields, which only described the current list.
- A run where no location has data now fails with a clear message instead of succeeding empty.
- Rows are saved in one batch per location: faster runs.
- Dataset fields are documented in the output schema, with a separate History view.
- Removed Bangladesh (
bd), which the source does not cover.
- README and input descriptions now say the history spans about 20 hours (24 snapshots), not a full 24.
First release: current X trends for countries and cities with 24-hour rank history, new-trend flag, cross-location overlap, optional full hourly history.
