Wolf CGB-20 / BM-2: 404 Error on config download and "MF fail" at address 08

[nowi967]

System Environment:

Boiler: Wolf CGB-20 (BAI/HCM)

Controller: Wolf BM-2 (GA 08)

Other Modules: Wolf MM/SM (GA 30)

Hardware: eBUS Adapter (Firmware 20260118) in micro-ebusd mode.

Integration: MQTT to Home Assistant.

The Problem: My adapter successfully connects to the bus and "sees" the masters, but the automatic configuration download fails with a 404 error for the BAI/HCM and BM-2 components.

Log Snippet:

Infoebusd: seen 10
Errorebusd: unable to download/store 5008..hc.ead ... 404 open
Status: 08: *recv, MF fail

Observations:

Address 10 (BAI/HCM): Identified as "seen", but no CSV is loaded, so all entities in Home Assistant remain "Unknown".

Address 08 (BM-2): Returns MF fail, preventing the adapter from identifying the correct manufacturer ID and loading the 08.csv.

Configuration Tab: The "Config path" field is not visible in the Web-UI (even in Admin mode), so I cannot easily point it to a local mirror or a different GitHub branch.

Questions for the community:

Is there a specific CSV branch or a manual URL I should use for the Wolf BM-2 / CGB-20 combination to avoid the 404 error?

How can I force a configuration path in micro-ebusd mode if the field is hidden in the Web-UI?

Does the MF fail on GA 08 usually indicate a hardware/timing issue or just a missing definition file for the Wolf identification string?

I have already tried manual scans via MQTT (eas/ebusd/scan), but without the translation files, the entities stay unpopulated. Any help or hints on where to place local CSV files on this adapter firmware would be greatly appreciated.
