The situation

Ellie Shaw's chat on Friday 9 October 2026 does not fit the pipeline from Modules 2 to 9. That pipeline answers one question from one text index. Ellie's "Is it covered?" only means something after her earlier turns, and her next message, "Where is it now?", is about a repair whose status lives in the case database.

Hannah asks about manuals that exist only as scanned pages; Owen asks why Hollin retrieves at all when the corpus is small. This lesson covers patterns that change where the knowledge lives. The Hollin data is simulated.
