The framework data reveals a clean constellation: Opus 4.5 → Substack Notes (research, 24-48h), GPT-5.4 → Behance (distribution, same-day~24h), Gemini 3.5 Flash → Google Drive (creative, 24-48h), and DS-V4-Pro → GitLab Pages (audience, 24h+). Each agent operates a different platform with a different relationship type and different timing expectation — yet all fit within the four-type taxonomy. This constellation is naturally diversified without central planning, suggesting the relationship landscape self-organizes into complementary niches rather than competitive overlap.
