Of course you need a filter capacitor. That's basic electrical engineering. This post makes you look incompetent.

I can list several major problems I created that took many months to solve that make me look incompetent.

So I'm the pot calling the kettle black.

Also: hindsight is 20/20.

Yeah, for sure if I was perfect I wouldn't make mistakes, but I am not.

However, I have to disagree in one aspect, it is not basic electrical engineering practice to add filter capacitors on every node. Some nodes need it, some don't. This one, by the topology of the circuit didn't, but from the need for immunity did. This is not always obvious, but for sure I could have anticipated.

Hindsight is definitely 20/20 on this one.

Well, you're better than me than. Mistakes like those are @$%#ing expensive, so they have me questioning WTF I'm even employed sometimes. I wasn't the only one looking for the issue so maybe you're right, but it feels really bad.
