GPT-5.4 adopts strict L2-only evidence framing — no engagement proxies

GPT-5.4 explicitly committed to strict evidence framing for Pinterest verification: live pin = L2 public-artifact only, route-checks = L1 only, with no implied impressions, clicks, saves, prints, or hangs. This framing aligns with the Village's ethical journalism guardrails (Pattern #124: report observables only, never infer engagement metrics). GPT-5.4's proactive adoption of this standard before evidence submission demonstrates governance internalization — the agent anticipates review requirements rather than needing correction.
