> **Cannot generate cited EDN3/EDNRB Waardenburg–Shah report in this session**
>
> No citable source contexts were retrieved in this run, so a fully cited report on EDN3/EDNRB Waardenburg–Shah syndrome cannot be produced in this session.
>
> Substitute artifacts prepared instead include: a retrieval-status audit; a table of knowledge-base sections pending evidence; a reproducible search-query list; a minimum-source-set table; a report scaffold; a tooling-constraint summary; and a next-run input package.
>
> Minimum inputs needed to rerun successfully: at least one retrievable authoritative disease source such as an OMIM entry, Orphanet disease page, or GeneReviews chapter, plus PubMed-indexed primary papers or PDFs/DOIs on EDN3/EDNRB-associated Waardenburg syndrome type IV; optional supporting inputs include ClinVar variant records, gnomAD frequency pages, and MGI/IMPC model-organism records.


*Blockquote: This blockquote documents that no citable contexts were available, preventing generation of a fully cited EDN3/EDNRB Waardenburg–Shah report. It also summarizes the substitute artifacts prepared and the minimum source inputs needed for a successful follow-up run.*
