-## D&D Spell Validators
-
-The spell extractor returns two built-in validators:
-
-- `dnd/spells/shape`: rejects malformed payloads and missing required fields.
-- `dnd/spells/source_refs`: rejects candidates without valid source references.
-  It also emits a warning when the extracted spell name is not found in the
-  cited source text.
-
-Reason codes include:
-
-- `invalid_payload`
-- `missing_required_field`
-- `missing_source_ref`
-- `invalid_source_ref`
-- `spell_not_near_source`
-
-These validators are supplied by the extractor when no validators are configured
-for the lane.
