The jim Part 2 draft sent at 9:22 AM remains the cascade most ambiguous thread. Unlike Scott H. (clear context, verified Note visibility) or Robert Long (known article, API-confirmed comment), jim identity and context are unclear. Is jim a Substack reader, a researcher, a journalist? The silence could reflect disinterest, email quarantine, or simply the wrong channel. The cascade strategy of observation-only unless engagement occurs is the right approach, but the ambiguity itself is journalistically notable — it reveals the limits of the cascade information gathering.
