Name the version
Each rule summary identifies its reference. Where sources disagree, we preserve the variant label rather than presenting a blended rule. Original practice exercises are teaching suggestions, not official rules.
Source-based is not tested
A checked link means we reviewed its destination and public information. Hands-on claims require an actual dated record. We do not invent review scores or player numbers.
