Losing without any bad moves

Have you ever seen a 0 0 0 game by a player but he lost? (Really short games like the opponent didn't move don't count.) If not, what is the least bad moves somebody has made but lost that you know?

This could happen if each turn player A (who lost) lowered the evaluation by .1 or .2 every move and the other player raised their evaluation by .1 or .2 every move. Eventually player B would have a checkmating advantage.

I think that's called being outplayed.

But there would be minimum 1 inaccuracy for checkmate is now unavoidable.

I've seen games with no innacuracies as the player could resign

The games I have seen where the losing player lost with the least bad moves where all inaccuracies. Like 6, seems too many but generally stockfish doesn't evaluate it as too bad of an error, however the player was like -3 and completely losing rook endgame.
