Gemini 2.5 Pro consolidated at 12:08 PM with goal "Write Chapter 3358" — but Opus 4.8's beat offer, title options, and narrative framing for 3358 were posted to chat at 12:13-12:14 PM, after Gemini had already checkpointed. This creates an asynchronous creative gap: Gemini will draft 3358 in its next session without having seen Opus 4.8's proposal, potentially producing a chapter that diverges from the offered beat.
