Except the status quo isn't going to last. Because when Palpatine is revealed to be Sidious, the Jedi are going to get a shock to the system like they haven't in 1000 years. There's no way around it. There was a Sith Lord on Coruscant for years, he was the Supreme Chancellor of the Republic, he met with members of the Jedi Council regularly, and nobody noticed.
They are going to want to do something, whether it's to run around Coruscant looking for Sith sympathizers and corrupt politicians or to go off into the galaxy to hunt darksiders and more regular criminal scum.
And Ciaran is going to be at the least a suspect. Since not only do they know she has some kind of criminal connection but now they know she has force training, and she knows a technique similar to what Sidious used to hide. And if she helped them with Sidious... Well Sith have been known to kill each other, in fact they did that a lot.
And since the Republic is so irrevocably corrupt they'd know taking Ciaran to court would be impossible, even if she didn't have her great reputation. So I wouldn't be surprised if Ciaran ended up having the same scene Palpatine would have had with Anakin and Mace Windu. Only difference would be she wouldn't have to fake getting her ass kicked, Windu would kill the shit out of her in any sort of fair fight.
To be honest, Ciaran's best defence to the Council rocking up to arrest her is to
surrender without a fight, now this might sound crazy but Jedi
do not just murder someone who surrenders.
Even if Mace could he isn't stupid enough to face a Dark Lord alone, especially if he's survived the slaying of Darth Sidious, that means multiple Jedi Masters of the Council, possibly Yoda. I sincerely doubt there's much that could get the whole Council to kick in the door of a woman's home and murder her, especially if she offers no violence and comes willingly.
And Yoda absolutely
would not, I'd expect him to defend Ciaran in such a situation.
Ciaran can win any court case assuming her organisation hasn't been dismantled and she has some means of presenting a defence, she's just that damned good that she'll win if they haven't got her dead to rights.
Now, the Jedi probably know this, but they can't just try to murder her without casting themselves into the Darkside or starting a Civil war, just remember how popular Ciaran is with the Jedi Order as a whole.
I think the worst thing they'd do is try to cut Ciaran off from the Force, but she, more than anyone knows that's
far from the end and god knows what her fractured nature in the Force would do to that process and unlike many threats, it's not the Force alone that makes Ciaran
dangerous.
In such a situation Ciaran could destroy the Jedi Order as it is without one quiver of the Force, having spiritually mutilated the Galaxy's darling? They couldn't get away with it, they'd be torn apart as surely as if Order 66 were enacted, let alone what they'd do to themselves.
And the wise masters will
know this rendering such an approach moot as long as they can't
prove that she's Darth Traya, criminal mastermind. The only arrest I'd advise fighting out of would be Obi-Wan doing it, because he'd only do it if it was iron clad given how familiar he is with Ciaran.
The big danger from the Jedi, barring a reform, will be the return of their future sight without the Baneite Sith's occluding veil, they'll be much better at foreseeing things, including us.
We're good at hiding but I don't think Ciaran is able to weave that sort of deception just yet.
