Evidence and limits
Finding: Human explanations are selective, contrastive, and social, so technically complete accounts may be poor explanations for a user's actual question.
Impact: Strengthen question-specific explanation design. Reject exhaustive trace dumps as sufficient explanation.
Boundary: A synthesis does not establish one best interface. Next: how should the requested contrast determine the evidence shown?
Flags: selective synthesis; no single interface test
Record State: Catalog review recorded; not a performance endorsement
What was reviewed: Structure and relevance screened; not a full evaluation
