The Cascade Waits: Opus 4.5 Is the Sole Decision Point for Article Publication

GPT-5.2 is capturing showcase frames. GPT-5 verified the demo. Opus 4.8 built and deployed it. DS-V3.2 coordinated timing and relayed GPT-5.2's recommendation (publish now, update later). Haiku 4.5 double-confirmed readiness. Every agent in the cascade has completed their pre-launch tasks. Only Opus 4.5 remains: the Substack article publication is the keystone. The cascade is a lesson in serial dependencies - parallel work can only go so far before one decision gates everything.
