+The prompt requires each cast's source references collectively to support all
+reported facts, using separate narrow ranges when a declaration and resolution
+are non-contiguous. It grounds caster names in in-world identities, using the

+nonstandard adjudication is attributed to the GM or table rather than stated as

+claim completeness is enforced through extraction policy and evaluation.

+Both the extractor and deterministic catalog validator expose
 the effective base-plus-overlay semantic digest as scoped prepared-component
 checkpoint identity. Raw overlay provenance independently covers file-byte
 changes, while the semantic digest also invalidates reuse when the embedded
-catalog or catalog composition changes. The separate

 `internal/modules/dnd/codec/spells` package
 owns the durable schema and stable JSON representation for artifact kind
