Global Synchronizer / CometBFT

I’m trying to get a deeper understanding of how the synchronizer works. In the diagram for splice it shows CometBFT being used as part of the Super Validator.

Where can I find the code related to the synchronizer and cometBFT connection? I’ve not had any luck finding it in the github Canton repo. Thanks in advance!

The Global Synchronizer currently uses standard open source CometBFT as a sequencer backend. The CometBFT sequencer integration is currently not open source.
