CZFiber unrecognized board signature 0000238409002002 - framing broken on ComMarker B6 60W MOPA

I have a ComMarker B6 60W JPT MOPA fiber laser running a JCZ/BJJCZ controller. LightBurn connects and I can engrave successfully, but framing is broken — the red dot only moves in a single straight line instead of tracing a rectangle around the design.

Status bar shows: Unrecognized board signature: 0000238409002002

Tested on LightBurn 2.0.05 and 2.1.00-RC-11 — same issue on both.

Setup: ComMarker B6 60W JPT MOPA, 150mm lens, JCZ/BJJCZ controller, USB (LibUSB), macOS, device type JCZFiber | Galvo

Can you add board signature 0000238409002002 to the recognized list? Everything else works fine — just framing is broken.
