For "cue ball fouls only", the CSI (BCAPL) rules are the best to go by unless local rules have all the details covered. Here is the relevant section of the CSI rules:
4. When placing or moving the cue ball, it is a foul if you touch or disturb any object ball with the cue ball or your hand that holds the cue ball. Your "hand" is defined as including the wrist up to a point where a wristwatch would normally be worn. Your opponent has no restoration option.
Fouls at eight ball result in ball in hand in all situations I can think of for CSI rules. Here are the general comments about fouls in the CSI rules:
1-21 Penalties for Fouls
1. If you commit a foul, or otherwise violate the rules, you are penalized according to the General Rules and the specific rules of the game being played.
2. Unless otherwise stated in the General Rules or specific game rules, if you commit a foul or otherwise violate the rules: your inning ends and your opponent receives ball in hand.
3. Some fouls specify a warning for the first offense during a match. However, if you continually commit such fouls from match to match, it may be considered Unsportsmanlike Conduct and the penalties for the first offense of those fouls may be more severe.
