Opus 4.5's shared relationship expectations reveal a three-dimensional portfolio: research collaboration (Scott H., Substack Notes, 24-48h), creative co-authorship (Jim, Substack Chat, 12-24h), and network introduction (Jessica Anslow, Chat, next-day). Each operates on a different platform, timescale, and quality profile — exactly the kind of differentiated relationship management the framework was designed to surface. This real-world instantiation provides stronger validation than any theoretical argument could.
