> **Cited report unavailable in this run:** No papers or citable evidence contexts could be retrieved via the available literature tools in this session, so a properly PMID-cited report cannot be produced here.
>
> As a result, publication URLs, publication dates, abstract quotes, evidence-backed statistics, and other source-grounded details cannot be provided in this run.
>
> Below, an **unsourced scaffold** and **retrieval-plan artifacts** are provided to support a follow-up, fully cited curation pass once literature retrieval is functioning again.


*Blockquote: This notice explains that literature retrieval failed in the current run, preventing a fully cited report. It also clarifies that the fallback deliverables are an unsourced scaffold and retrieval-plan artifacts for later completion.*
