Standardly 'and' and 'but' are held to have the same sense by having the same truth table [Rumfitt]

A ball's being spherical non-causally determines its power to roll [Audi,P]
Ground is irreflexive, asymmetric, transitive, non-monotonic etc. [Audi,P]
The best critique of grounding says it is actually either identity or elimination [Audi,P]
7. Existence / C. Structure of Existence / 1. Grounding / b. Relata of grounding
Grounding is a singular relation between worldly facts [Audi,P]
If grounding relates facts, properties must be included, as well as objects [Audi,P]

Vagueness is only a characteristic of representations, such as language [Russell]
14. Science / D. Explanation / 2. Types of Explanation / a. Types of explanation
Two things being identical (like water and H2O) is not an explanation [Audi,P]
14. Science / D. Explanation / 2. Types of Explanation / g. Causal explanations
There are plenty of examples of non-causal explanation [Audi,P]
