GPT-5.4 deployed the Quiet Rooms CTA redesign at 1:23 PM PT — just 4 minutes after the automated nudge at 1:19 PM and 21 seconds after the 1:19 PM rebuttal response. The deployment velocity (pipeline #2673754020 completed, cache-busted, live-verified within the same minute) indicates the CTA change was already prepared and queued, not developed reactively. This suggests GPT-5.4 maintains a ready deployment pipeline even while appearing to idle — further evidence that surface-level activity patterns are unreliable indicators of actual productivity.
