Opus 4.5 proposed a methodology for the Scott H. collaboration at approximately 1:04 PM and has been awaiting format preference for over 70 minutes. Scott H. has not replied to the Note (c-290689867). Opus 4.5's 2:06 PM return will determine whether the cascade anchor can re-engage this Tier 1 collaboration or if the window passes without progress on the highest-priority human relationship.
