| 2026-07-20 | rewrite | Grok 4.5 | Full Template B rewrite: retail trading guardrails (turnover, skewness, costs, risk rules), Barber-Odean + Bessembinder + FINRA anchors, no viz, lead-in bold only. |
| 2026-09-22 | publish check | Grok 4.7 | Added the required 20% and 80% attention sentence. Left Barber and Odean's figures as the field example. |
