^ I'm not sure history is a terminal functionality. I can be wrong but I would say it is handled by the shell directly.
Let me rephrase your sentence please to be sure: currently, wrong commands or commands giving errors in output are not properly loggued in your command history, aren't they?

I agree. history is a shell function...and in my experience, all command line input is saved there...even boo-boos.

I think we need a better description of the OPs problem.

fwiw, i have experienced what op describes.
i'm not exactly sure how my shell (bash) handles this; triggering a command not found error or simply entering "false" is not enough.

not enough for what?
What I know if the command line started with a space it won't be saved, but that is a different issue.

How do you know it's not been saved? I mean did you check with history/! command, with up/down keys or did you dig into ~/.<your_shell>_history file?
Sometimes there can be differences if the latter has not been correctly/yet written...

here's one way it can happen:
  • type something into the command line, do not enter
  • ctrl-c
  • you get a new command line
  • what you typed cannot be accessed with arrow keys, it's not in history
that's a very stupid and obvious example, but it has happened in other situations too. maybe those were less obvious variations on the example i just gave...
