Reminds me of days gone by. Nice sleuthing and solutions. You know you only need one fault to make your day. Five faults are an absolute blessing. I reckon 3. Keep up the great work.

Could not find the boring part.

Looks neat. Good to see you are looking at EMC improvements and testing. FWIW His Muskiness' Minions are very keen on Via Fencing (looks like MG might be too) and putting common mode chokes on power supply and CAN connections. Might be worth a look. Via fencing is basically free these days unless you go crazy on the number of holes.

One hackable idea: add 3rd current sensor and made from it off-grid 3 phase inverter with asymetrical outputs ;) Great job, Damien!

Aha! I found a loophole in your pronunciation of three. When you say 3D, the TreeDee slips out. Not so smart NOW, are ya? ... I appreciated this look. As someone who's never designed a board in software, other than old MS Paint and doin' the dip in ferric chloride, I was able to follow most of this and understand what's going on and your solution to it. Leagues away from applying that information myself, but, it was dumbed down enough to at least keep up.

I say the board has zero mistakes because I reviewed it 🤓🤓

I really don't like this new cat-free format.
