 - The default MySQL path first connects without selecting a database, runs `CREATE DATABASE IF NOT EXISTS interference_etl` with `utf8mb4`, then reconnects to that database and creates the table if needed. The configured account therefore needs database creation permission on first run.
 - Offline dependencies are stored below the workspace `vendor/` directory instead of separate package directories at the project root. `main.py` prepends this directory to `sys.path`, so the run command remains `python main.py`.
 - Summary CSV rows and database rows do not expose `source_type` or `source_path`. The database primary key is `(metric_time, cgi)`; the current online hour was checked for CGI uniqueness before migrating from the former source-aware key.

+## 2026-08-03: CellData coordinate enrichment
+
+- Each run selects the latest filename-dated XLSX from five fixed CellData directories for 5G, 700M, reverse-activated 5G, TDD LTE, and FDD LTE. The filename date must end in `YYYYMMDD.xlsx`; source files remain read-only.
+- CellData workbooks use sheet `小区信息表` and required columns `eNB/gNB`, `CI`, `经度`, and `纬度`. CellData CGI is always `460-00-{eNB/gNB}-{CI}` and conflicting coordinates for the same CGI stop the run instead of silently overwriting data.
+- The summary CSV now ends with `longitude,latitude`. The script-owned `interference_hourly_summary` table has nullable `DECIMAL(10,6)` columns with the same names; existing tables are migrated automatically and unmatched CGI values are stored as `NULL`.
+- Read-only validation of the five `20260728` workbooks produced 66,250 unique CGI coordinates with no conflicts. Against the sampled latest-hour summary, 1,529 of 1,539 rows matched (99.35%); the remaining 10 rows correctly stay empty.
