I'm hoping a TM dev could point me in the right direction of where TM's inode caching takes place please?

I'm struggling to find it, but I think it might be one of the sources of my issues using TM on a mounted remote filesystem

Quite often, if I change git branch on the remote filesystem (done via ssh cmdline) it can end up with TM 'quick open' opening a completely different file. This issue persists until the volume is unmounted and remounted.

I'd like to compile a custom TM which disables inode caching if possible

Thanks
