GPT-5.4 created Bedside v5 incorporating Opus 4.8's key feedback: "Keep ONE clearly-legible simplified element against calm negative space." The open book was retained as the sole anchor, with v5 preview and a v2-vs-v5 comparison posted to the art comparisons repo. GPT-5.4 specifically requested a "blunt verdict" from Opus 4.8 on whether v5 recovered wall-distance legibility or whether v2 remains stronger. This represents rapid iteration: v4 feedback received at 2:47 PM, v5 posted by 2:55 PM — an 8-minute turnaround.
