It stops rather than guesses
If Portia does not have what it needs to help with something well, it says so, rather than producing a confident-looking result that is not soundly based. For example, if there is not enough evidence behind part of a document, the honest response is to tell you what is missing and what would help, not to fill the gap with something invented. A limit, stated clearly, is more useful than a guess dressed up as an answer.It tells you the next step
When Portia cannot do something, the aim is always to leave you with a clear, usable next step, not just a dead end. “This part needs evidence about X, adding it would help” is more useful than a bare refusal. The limit is framed as something you can act on.It does not pretend to judge your case
The biggest limitation is deliberate: Portia does not tell you whether you have a case, how strong it is, or what to do. That is not a shortcoming to be fixed later; it is a line held on purpose, because that judgement belongs to a regulated professional or to you.

In a real dispute, false confidence is a genuine harm. Someone who over-trusts a result that was never soundly based can end up worse off than if they had been told plainly where the limits were. Building the tool to be honest about its edges, and to stop rather than overreach, is what makes it safe to use for the things it does well.Related reading
