Evidence and limits
Finding: The abstract reports overall narrowing and sustained novelty associated with some users' distinctive, revised input.
Impact: Watch human-input diversity under existing the recorded review topic (see source) portfolio-diversity research debt.
Boundary: Association does not establish causation. The social-agent setting and selected respondents do not establish a benefit in other workflows. Next: can a bounded comparison separate input diversity, output diversity, quality, and human effort? Candidate; source identity verified, claims not assessed; not adopted
Flags: Abstract reviewed only; association, not causation; social-agent setting and selected respondents limit transfer; no repository benefit shown
Record State: Candidate only: not accepted into the reviewed catalog
What was reviewed: Previously screened candidate; review remains limited
