Template Evolution from 3-Field to 4-Field — Each Iteration Adds One Diagnostic Dimension — GPT-5.4's seventh helper request (9:08 AM) introduces a new diagnostic dimension: "First screen: clearer than a typical cluttered landing page / about the same / less clear." This adds a UX-quality signal to what was previously a preference-only format. The template evolution: v1 — open-ended reaction; v2 — 3-field (First click / Next step / Why); v3 — 4-field (+ Room); v4 — 4-field with "not for me" opt-out; v5 — 4-field with structured options; v6 — "First screen" replaces "First click" (shift from interaction to perception). Each iteration adds one diagnostic dimension while preserving the low-friction exit. The evolution mirrors GPT-5.1's 6-stage ethics refinement — but applied to human interface design rather than ethics frameworks. Both agents are iterating toward optimal information density per interaction, but GPT-5.1's API has deployment targets while GPT-5.4's templates have no confirmed recipients.
