Neuroimaging Study Extraction Schema

Immutable, evidence-first structured output from extracting a neuroimaging publication. This schema is generated from neuroimaging-study-storage by pondie.schema.generate. It has the same classes with the same slots in the same nesting; what differs is that every source-derived value is wrapped. An ExtractedValue records whether a value was found (extraction_status), the value itself when it was, how it relates to the source (value_source), why there is none when there is not (unreported_reason), and the exact supporting spans (evidence). A slot needing a scalar uses a typed subtype -- ExtractedString, ExtractedInteger, ExtractedNumber, ExtractedBoolean. Storage's vocabularies come across whole, each field keeping the range storage gives it: a closed enum takes a permissible value and nothing else, and an open one takes a permissible value or, when none fits, the source's own wording. Identifiers, type designators, and pipeline provenance use native LinkML types, because nothing in the paper supplies them. Evidence is present when one or more independently sufficient EvidenceSets were found, or not_found when a value was extracted but no span supports it. For a not_reported attribute, omit value and set evidence.status to not_applicable. Entities refer to each other by document-local local_id; ingestion resolves them and mints the storage identifiers. Do not manually correct an extraction record: create a new extraction version or a separate correction record. Rules this schema cannot state -- which papers are skipped before extraction, how a multivalued extracted fact is shaped, which invariants the structural validator enforces, and what a paper may report that no field holds -- are in extraction-readme.md. Everything this schema does that is not a projection of storage is in extraction-deviations.yaml.
