A seeds core product surface: a tested Reddit path graph parser, event reducer/ranking (including issue #146 star-topology fix), form JSON hole-fill + HtmlUiAction, and the vote-compare page—durable architecture despite some .tdsl notes and terminal-paste noise in forms/ranking. B only tweaks sibling nav so each unranked isolate is its own group plus one regression test (#130), a correct but narrow UI fix on existing garden code.
