 `nearby_count` is the number of other high-interference cells from the same selected time group within 1 km, across all network types. The cell itself is excluded, the 1 km boundary is included, and rows without coordinates use `0`. Candidate cells are found through a 1 km spatial grid index and confirmed with exact Haversine distance.

+When multiple retained source rows have the same CGI, the summary keeps the row with the numerically largest interference value. Equal values keep the first row encountered. Deduplication happens before nearby-cell counting and database insertion; converted source CSVs remain complete.

 `prev_interference_dbm` and `prev_nearby_count` come from the previously retained database time, matched by CGI before the current batch replaces old rows. They represent the same cell's previous-period interference value and nearby high-interference count. On the first run, or when a CGI did not exist in the previous period, both fields are empty in CSV/history output and `NULL` in MySQL.

 The script never modifies or deletes source storage files. Before downloading source ZIP files or CellData, it compares the normalized target time with the database. A target already present, or older than the database, is not processed again.
