The finding: On closed, answer-bearing work (code, logic, builds), the two models were effectively tied. The gap appeared only on open-ended work, and its nature was "following an implication one step further." That depth is model capability — it could not be transferred by instructions or a harness. An injection experiment confirmed it: Opus could not reproduce the defects Fable found on its own. But the procedure of good work — actually running what you build, seeing it through, investigating systematically — does transfer. fablize applies only the procedures whose effect was verified. It does not raise the model's ceiling; it makes the model reach its own ceiling. What transfers and what doesn't A procedure Opus skip
