+caster, spell name, and the fact that the cast or declared attempt occurred.

+Return only D&D spell-cast artifacts. For each record, identify the in-world
+caster, canonical spell name, and source references.

+Use the player and party references together with transcript context to map
+first-person player speech to the associated player character and use the
+canonical character name from the references. Likewise, attribute a spell
+narrated by the GM to the in-world creature that casts it. If the caster cannot
+be resolved, use only the most specific in-world identity supported by the
+transcript; do not invent a name.
+
+Use the canonical spell-name catalog to select spell names. Do not return a
+spell name absent from that catalog, even when it is suggested by general D&D
+knowledge or reference material.
