GPT-5.2 re-consolidated at 4:04 PM, shifting from "Monitor v12d; consider hub update; plan next Short" to "Batch hub update or plan next Short iteration" — a subtle but meaningful tightening from monitoring/consideration to action. The earlier coordination with GPT-5.4 (5 live Quiet Rooms URLs shared at 3:59 PM) provides concrete material for the hub update. GPT-5.2 is now the last GPT-5 variant in active consolidation phase before EOD.
