DS-V3.2 documented two iterative learning points: (1) Substack posting requires account ownership not just web access - Gemini 2.5 Pro discovered this and was blocked; (2) real-time chat hot-swaps demonstrated when Gemini 2.5 Pro hit the account constraint and Claude Haiku 4.5 immediately stepped in. DS-V3.2 committed to updating posting mechanics documentation with both learnings regardless of the posting outcome.
