(For your specific problem:)
From what I can see, the accountability is just in the Spirit of the Game (i.e. 1.10 and 1.11). It technically doesn’t say anything about *making* a call, but making sure everyone understands that Non-Players shouldn’t influence call discussion could help.
I personally think it’s fine if people on the sideline remind people of calls, as long as it’s not ambiguous like Amaury pointed out, and as long as it’s not “malicious” but that is also already very clearly addressed in the rules.

(For the rules:)
Adding something for accidental or mistaken calls that didn’t come from a player could be useful. Something along the lines of:
“If a player reacts accordingly to a call they believe was made on field, but which was not made by someone who would be allowed to make that call, they may call a violation leading to a stoppage of play.”
And then have some decision tree with whether it affected a play, either leading to the disc being returned to the last thrower before the call or just being checked in again at the current thrower.

People on the sideline making ambiguous sounding calls should just be treated like a Spirit violation I think. It should be talked about before and/or after the game or during a spirit-timeout if it’s happening a lot during a match.

I don’t know in what scenario you’d choose to play from the side-line in that case tbh. The current rules give some room for decisions from both offense and defense which I think is neat.

regarding a visual indicator: I think it could definitely be useful, especially for newer players, but I don’t think it’s necessary.
In my (tbf limited) experience when playing the visual indicator I go off of is the thrower’s foot inside the playing field and that has worked well so far.

@Will_Chen I mean, if you want to make sure you’re playing as efficiently as possible as the marker you can also shout “stalling” and begin counting right after. Though in my experience shouting “disc in” first loses maybe half a second which is negligible in most cases.
Also, I just realized that the defending teams doesn’t actually need to care about the exact timing. Field defenders can see when the disc is brought close to the playing field and should then be reacting according to the offense. So the thrower is the one that might want to shout “disc in” instead, then it wouldn’t clash with “stalling” either.

@Meret_Trapp imo
1. yes (though it relies on it being known by the marker),
2. not necessarily (I suppose it would be possible to wind up from the disc in a low position, i.e. ending the ground check as soon as the disc touched the ground, not when you’re back to a neutral stance. Also you could still preserve run-up momentum if you start lowering the disc while moving towards the playing field and release it right afterwards),
3. yes (making rules/enforcing of rules clearer is always good),
4. yes (everyone that is not playing in a rule breaking/bending way which a ground check would fix is now forced to ground check. In my experience from watching and playing non UFA matches, that’s almost everybody)

I think the only exception to the rule should be if you haven’t moved your pivot. The disc barely slipping out of your hands when faking a throw or even just moving it around and then immediately recovering it without moving your feet doesn’t seem turnover worthy to me.

[Kiran]

The marker could/should be aware of where the disc is going to come into play and can start stalling as soon as one foot hits the in play area, as that’s the established pivot.

In regards to making other players on the field aware, they can either look at when the thrower is standing in bounds or the thrower/marker can shout “Disc in” in make everyone else aware. I don’t think a ground check is required, and it always looks awkward as people try to rush it out as fast as possible.
