 The database table contains normalized `metric_time DATETIME`, `network_type VARCHAR(16)`, `interference_dbm DECIMAL(10,3)`, nullable `prev_interference_dbm DECIMAL(10,3)`, nullable `longitude` and `latitude`, `azimuth DECIMAL(6,2) NOT NULL DEFAULT 0`, `nearby_count INT NOT NULL DEFAULT 0`, and nullable `prev_nearby_count INT`. A successful transaction replaces the target batch and deletes every other database time, so the table retains only the latest processed group. The previous-period values are read before this replacement transaction.

 The filename time comes from normalized `metric_time`, never the server clock. If the database already contains the target time but its history CSV is missing or empty, the script exports that time from the database and repairs the history file without reprocessing source data.
 
+All generated CSV files use GBK without a UTF-8 BOM, including the seven converted source files, the merged summary, and the uploaded history file. `manifest.json` remains UTF-8 JSON.
