How do damage multipliers stack?

I've been wondering how multipliers stack since I got hold of Old Faithful, which deals x2 damage when the enemy hit was on full health.

Do we know how this interacts with stuff like sneak attacks? (especially when this gets ranked up beyond x2) Or critical hits? or both?

I can think of several possibilities (using x2 Sneak and x2 for full HP):

Double the doubled damage. (Damage x2) x2
Both effects applied to the base damage, and then added together. Damage x2 + Damage x2
Adding the multipliers together before muliplying? Damage x(2+2)
Only the largest multiplication effect works? Damage x2

I've had a look around google and the fallout wiki (the page for the weapon says x4, but doesn't justify this), but haven't found an answer for Fallout 4.

There is a similar question, but it is about criticals and sneak attacks specifically.

Based on what I have seen 1 shotted with instigating weapons the x2 modifier for the enemy being full health counts as the base damage. So if the normal base damage was 100 it would be 200 multiplied by the crit and sneak attack bonus. Reason I say this is because you can 1 shot the mirelurk queen or behemoths with the correct instigating weapon while a normal version of the weapon with all the same stats except the instigating modifier appears to do about half as much damage. So the first option 1. (Damagex2)x2 would be the correct answer.

These multipliers do not stack; for example, picking up both Cricket's Head and Magic Mushroom will result in an overall 1.5x multiplier rather than the expected 2.25x.

How does damage multipliers work?

A damage multiplier is the number that the base damage of a weapon or attack is multiplied by to yield the actual damage. Although the values of the numbers have changed throughout the series, generally shots to the head and neck increase damage, while hitting the limbs and hands will decrease damage.
