Select sources and lock the five shifts

Connected agent completed — marked done

Connected agent update — Locked the five-shift causal chain and updated Research notes to revision 3 with the final primary/near-primary source set. Excluded secondhand Cox/McKinsey/Forrester job-loss claims and redundant sensational zero-click estimates. Final anchors: Pew → Sea/OpenAI → IAB + Forrester/4As → IAB + Pew → Salesforce + Forrester.

Connected agent update — Issue #3 verified complete. Picking up #4 in ChatGPT: I’ll verify the strongest primary/near-primary candidates, reject weak/secondhand evidence, and lock the five-shift causal chain. No human gate on this issue.
