An idea came up in a discussion recently and I am trying to determine broadly how a rule is intended to be taken. I have also asked about this in the Discord Server, but I wanted to see what people on the Forums think as well, both for posterity and because some old heads are around and might be able to shed some light.
Confidence
Important characters have a Confidence Score and Confidence Points. This includes both central player characters (magi and companions) and important NPCs, such as recurring antagonists and allies. These characters start with three Confidence Points. Most such characters start with a Confidence Score of one, but this can be modified by Virtues and Flaws.
There is no limit to the number of Confidence Points that a character can have.
Using Confidence
A player may spend Confidence Points on most rolls to get +3 to the total per point spent. He may decide to spend the point after the dice are rolled and the putative result of the action is known. He may not spend Confidence on a roll that botched, but he may spend it on a roll of zero which was not a botch. A player may spend any number of points up to, but not exceeding, the character's Confidence Score.
Once a Confidence Point is spent, it is gone forever. Confidence Points are not recovered.
Confidence may not be spent on rolls which represent a whole season's activities, such as rolls for studying from vis.

This description does a decent job saying what rolls you can’t spend Confidence Points on, but it doesn’t do much to describe which ones you can spend it on.
The text says you can spend points on “most rolls.” If it said “most of the character’s rolls” I would say that the rules support what my intuition said: any roll where the total being generated includes a Characteristic (or perhaps Ability) from a character can have Confidence Points spent on that roll by that character.
The text doesn’t say that though, it says “most rolls.” Moreover, it doesn’t say a character may spend Confidence Points on “most rolls,” it says a player may spend Confidence Points on “most rolls.” This seems to indicate that it doesn’t really matter which roll it is, as long as it fits the criteria listed after, that it can’t be spent on a botch, nor can it be spent on a roll representing a whole season’s activities.
Does that mean then that I could spend Confidence Points from my magus on a Defense roll my shield grog is making?
Can I spend them from my Companion character to boost another magus’ Casting Total to make sure they can Penetrate against a Mighted creature we’re fighting together?
How about on the SG’s Warping roll to make it harder for my magus to avoid Twilight?
If the answer to any of these is no, why? Is this just a shared intuition that’s so obvious that we can take it for granted that it was the intended reading? Or is there some text in another book or some writing of the authors that would clarify that these uses are invalid?
