Evidence and limits
Finding: Long-context models and retrieval improved some results but still lagged humans on long-range temporal and causal understanding, question answering, event summaries, and multimodal dialogue.
Impact: Strengthen causal, temporal, and multi-session evaluation. Reject a large context window as proof of durable memory.
Boundary: The conversations are generated and edited rather than operational records. Next: which failures persist when the source of truth is versioned repository evidence?
Flags: generated and human-edited dialogues; no repository custody
Record State: Catalog review recorded; not a performance endorsement
What was reviewed: Structure and relevance screened; not a full evaluation
