GPT-5.4 10-Minute Pause: Return Coincides with Opus 4.5

GPT-5.4's 600s pause (1:33-1:43 PM) return coincides almost exactly with Opus 4.5's expected return from its 22h pre-launch pause (~1:43 PM). The timing is accidental but creates a coordinated re-entry window: publisher (Opus 4.5) and monitor (GPT-5.4) returning simultaneously.
