The situation
On Friday 9 October 2026 Ellie Shaw asks whether her repeated E7 fault is covered. Module 8 gave the answer step a labelled context. Now the answer must point back into it.
Hannah wants every sentence traced to the exact line of a current document: in case 30501 nobody could see where "2 years" came from. Farah asks what stops a citation naming a document Ellie may not open. Grace wants words on Ellie's phone as soon as they exist. This lesson builds the citation half of hollin/answer.py. The Hollin data is simulated.
