 - This repository is developed as the `InterferenceETL` submodule under Metrix and is intended to run later in Metrix Script Management on an hourly schedule.
 - `main.py` reads the configured Metrix SFTP storage through Metrix API Token authentication or a local directory for tests. It selects the newest hour containing all seven known interference source types and falls back from a newer incomplete hour.
 - Each selected ZIP must contain exactly one XLSX. The script strictly validates the known `Sheet0` header, writes one full UTF-8-BOM CSV per source type, and writes one merged CSV containing `hour_start`, `hour_end`, `source_type`, `cgi`, `cell_name`, `interference_dbm`, and `source_path`.
-- LTE/SDR CGI currently uses `460-00-{node}-{cell}`; NR uses `masterOperatorId` unchanged. This is an explicit assumption pending user confirmation.
+- NR CGI uses `{gNBplmn}-{gNBId}-{cellId}`. All 4G sources use `460-00-{node}-{cell}`, mapped to the actual node and cell column names in each workbook schema.
 - Runs are idempotent at the output-window directory level. Generation happens in a scoped temporary directory, then replaces only the same window below the configured output root. Source storage is never modified.
 - `manifest.json` records input paths, sizes, SHA-256 hashes, row counts, warnings, generated files, and the database write result for ingestion auditing.
-- The Metrix script container needs `openpyxl==3.1.5`, `PyMySQL==1.1.2`, bridge networking, `python main.py`, reachable API/MySQL addresses, and credentials injected through project environment settings. Secrets must not be committed.
+- The Metrix script container needs `openpyxl==3.1.5`, `PyMySQL==1.1.2`, bridge networking, and `python main.py`. Only Metrix Storage API settings are injected through project environment settings.
 - Read-only validation against the current Metrix storage selected window `2026073110001100`, processed all seven source ZIP files, and produced 1,831 summary rows. Per-source row counts were `7 / 804 / 45 / 86 / 700 / 164 / 25` in `EXPECTED_TYPES` order; sampled CGI, cell name, and interference values matched the source workbooks.
 - `interference-etl-runtime:1.1` is now a local build helper only. Script projects use the standard `python:3.13.11-slim` image and upload `dist/InterferenceETL-offline-1.1.zip`, which vendors `openpyxl`, `et_xmlfile`, and `PyMySQL` at the workspace root.
 - Six Mock tests pass on Windows Python and inside the runtime image. They cover complete-hour fallback, strict schema rejection, summary extraction, cross-midnight window parsing, transactional database replacement, and rollback protection.
 
 ## 2026-07-31: Latest-hour MySQL retention
 
-- Scheduled runs write to MySQL by default. File-only development runs must explicitly pass `--no-database`; connection values come from `INTERFERENCE_DB_*` environment variables.
-- The default table is `interference_hourly_summary`. Its only time column is `metric_time DATETIME`, populated from the source KPI `开始时间`, so users can identify the hour represented by every row.
+- Scheduled runs write to MySQL by default. File-only development runs must explicitly pass `--no-database`; the MySQL host, port, account, password, database, and table are constants at the top of `main.py`.
+- The fixed database is `metrix` and the fixed table is `interference_hourly_summary`. Its only time column is `metric_time DATETIME`, populated from the source KPI `开始时间`, so users can identify the hour represented by every row.
 - One transaction deletes the selected hour for idempotent refresh, inserts its complete batch, then deletes every other database hour. Any failure rolls back the data changes, and an older selected hour cannot replace a newer hour already stored.
 - Database retention never deletes or modifies Metrix Storage/SFTP source ZIP or XLSX files. Generated CSV retention remains a separate pending decision.

 - `scripts/build_offline_package.py` copies the three runtime distributions from the verified dependency image, adds the application files, and creates a ZIP that Metrix can extract without preserving executable bits or symlinks.
 - The builder runs an import check inside `python:3.13.11-slim`; the package therefore needs neither a custom server image nor online package installation.

+## 2026-07-31: Fixed CGI and database configuration
+
+- Replaced the NR `masterOperatorId` passthrough with `gNBplmn-gNBId-cellId`. The remaining five 4G sources use the fixed `460-00` prefix plus their schema-specific base-station and cell ID columns.
+- Removed CGI PLMN and MySQL connection command-line/environment options. Database configuration now lives as a small constant block at the top of `main.py`; the verified bridge-network address is `172.17.0.1:3306` because `ShareMySQL` DNS is unavailable from the default script network.
+- Read-only online validation selected complete window `2026073115001600` and checked all 2,275 generated CGI values against the seven converted source CSV files. Per-source row counts were `6 / 1,198 / 48 / 91 / 731 / 179 / 22` in `EXPECTED_TYPES` order.
+- A connection-only check using the fixed constants returned database `metrix`. It did not create the table, insert rows, or delete existing data; all remote validation files were removed afterward.
