 - Database verification found only `2026-08-06 15:00:00` and 1,082 rows. Of those, 887 have non-zero `nearby_count`, the maximum is 40, and all 8 rows without coordinates remain valid. The history CSV was uploaded with the expected nine columns and 1,082 rows to `干扰历史数据/2026-08-06/干扰数据处理结果_20260806150000.csv`.
 - A second run `e1c81ada63234b3c85a377e1b46a1370` returned success with `status=skipped`, confirming that an existing database time plus a non-empty history file avoids duplicate work.
 - `MetrixApiClient` uses a proxy-free opener because the API is an intranet service and the Windows system proxy previously converted direct requests into `502` responses. The verified Metrix API remains `http://188.5.127.115:18271`; external port `9082` currently serves CapacityReport and must not be used by this script.

+## 2026-08-07: Previous-period comparison fields
+
+- Summary CSV, database table, and history CSV add nullable previous-period fields: `prev_interference_dbm` and `prev_nearby_count`.
+- Before downloading source ZIP/XLSX files, the runner still checks the current database time. When a newer source group is being processed, it reads the currently retained database rows before replacement and maps them by CGI. The current row receives the previous row's `interference_dbm` and `nearby_count`; unmatched CGI values remain empty in CSV and `NULL` in the database.
+- On the first run, when the database has no previous group, both fields remain empty/NULL. Existing-table migration adds both columns automatically. Twenty containerized tests pass, including first-run empty values, CGI matching, and nullable column migration.
