- 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.
- Offline package SHA-256 is `74EEA84058C5F14E7108B840561C070DC47752D67FEC68262F0CC6C78EE8EC0D`. SSH deployment run `984ffc6f98024a2d81b63d4359aabc71` processed `2026-08-07 07:00:00` with 820 rows and deleted 1,137 rows from the prior database time.
- Production verification matched 616 current CGI values to the previous period and left both previous fields NULL for the remaining 204 CGI values. `prev_nearby_count` matched exactly; `prev_interference_dbm` uses the table's existing `DECIMAL(10,3)` precision. Repeat run `6b38030f6d9e4ab1a0ee6a4ba0dc5d6e` returned `status=skipped`.
## 2026-08-07: GBK CSV output
- All generated CSV files now use GBK without a UTF-8 BOM: the seven full source conversions, the merged summary, repaired history exports, and uploaded history files. `manifest.json`, API JSON, and database character sets remain unchanged.
- The encoding is centralized in `CSV_ENCODING`; tests verify GBK Chinese bytes, absence of the UTF-8 BOM, summary parsing, and history parsing.
