/**
 * Layer 2 Semantic Extraction — LLM-assisted knowledge extraction from
 * a Markdown intermediate. Non-deterministic; produces attributed triples.
 *
 * Spec: 19_MARKDOWN_CONTENT_TYPE.md §3.2
 *
 * The LLM reads the markdown body and extracts structured knowledge that
 * the deterministic structural extractor cannot capture: claims in prose,
 * implicit relationships, entity mentions, and quantitative facts.
 *
 * Every triple carries extraction provenance so consumers can distinguish
 * structural (deterministic, verifiable) from semantic (agent-interpreted,
 * endorsable) knowledge.
