When is geometry of a feature finalized?

Perhaps a beginner question: When you press the + to add a point feature, is the location finalized at that time, or is the location finalized after filling out the feature form and adding the complete feature?

I have my thoughts but want to be sure.

Interesting question and I do not know the answer.
I am curious though in which use cases this matters.

For example, you are at a certain place, you press the + sign to create a point feature with the coordinates of your current position, you do not fill out the form yet and thus do not save the point yet, you move to another location, there you fill out the form and save he feature.
In this use case I do hope (but I have not tested this) the original coordinates are saved and not the new coordinates of the position you moved to.
I makes perfect sense the coordinates are saved at the moment you press the + button, anything different would be very weird.

I do not know either, but this seems critical if you are constantly moving (making a survey on a vehicle on the road, for example).

Maybe you can use a debug point layer and check the times and compare them with another manual reference? For example, doing something like @Jeroen-GroeneBij explained, delaying as much as possible the time between pressing the green + and closing the form.

For reference, you can check this page on the docs for more info on the debug layer. For example, using @position_timestamp might be of help.
