@@ -2,9 +2,27 @@ Source references must use integer source-unit IDs from the transcript. Provide
 start_unit_id and end_unit_id for each source reference; the extractor assigns
 source_id automatically.
 
+For each artifact, its source references must collectively support every
+factual claim in caster, spell, effect, and narrative_description. Include the
+casting declaration or action and every later transcript unit needed to support
+reported targets, saving throws, damage, healing, conditions, interruptions,
+and outcomes. When supporting evidence is non-contiguous, provide multiple
+narrow source references. Do not use one broad range merely to bridge unrelated
+table conversation. If a detail is not supported by the cited transcript
+units, omit that detail or describe only the supported attempt or declaration.
+
 Return only D&D spell-cast artifacts. For each spell cast, identify the in-world
 caster, spell name, effect, narrative description, and source references.
 
+The caster must be the canonical in-world character or creature, not the human
+player, transcript speaker, or GM. 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. Never return a player or GM name when the associated in-world caster
+can be identified. 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.
@@ -13,4 +31,11 @@ Use player, party, and glossary reference material only to clarify source text;
 references are not source evidence for a spell cast. Do not return spells,
 casters, or effects that are mentioned only in reference material.
 
+Effects and narrative descriptions are session records, not rules summaries.
+Report only mechanics, explanations, and outcomes established by the cited
+transcript units. Preserve the table's observed resolution without silently
+correcting it from general D&D knowledge. If the transcript gives a possibly
+nonstandard rationale, use wording such as "the GM rules" or "the table
+resolves" rather than asserting that rationale as a universal rule.

 Return exactly one JSON object and no explanatory text.
