-authoritative for what happened in this session, even when a table ruling may
-differ from published D&D rules. Do not correct the transcript or fill in
-unstated mechanics from general D&D knowledge. When a ruling or mechanical
-explanation matters, attribute it to the GM or table instead of presenting it
-as a universal game rule.
+Include an actual casting event or an unambiguous declared casting attempt.
+Exclude spell mentions, hypothetical plans, rules discussion, and catalog
+matches that do not establish a casting event in the transcript.

-aid; it does not establish that a spell was cast or how the spell works.
+aid and never evidence that a spell was cast.
