Production Multi-Tenant RAG Table-Aware AST Chunker & Numeric Citation Hallucination Verifier Kit (Node.js/TypeScript)

Markdown/HTML table-preserving AST chunker that re-injects column headers and full ancestor heading breadcrumbs ([Context: H1 > H2 > H3]) into every split table slice, plus a deterministic numeric/currency citation verifier that blocks hallucinated numbers before returning LLM answers.
