Fifteen practitioners (plus 1 cross-reference) whose writing systems are documented in depth — Wang, Pink, Deen's 27-pattern essay taxonomy, Orlean, Karlsson, MacCulloch, Whyte (cross-ref), Bilton, Macfarlane, Forsyth, Gawande, Powers (solitude-maelstrom), Hari (research-driven investigation), Popova (presence-over-productivity), Tucker Max (memoir truth-discipline) — in productive tension across process discipline, reader obligation, voice cultivation, rhetorical form, scene rendering, and the cross-batch convergence on truth-as-foundational-discipline. Reading Sequence at the top offers three entry-paths (foundations / single-method / craft-layer).
