This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Naoko Takeuchi's outcome attributable to any origin.
Structural luck, Encounter luck, Event luck, Outcome variance can change every arrow in the path. This successful-only dataset cannot observe the near-identical paths that did not break through, so luck stays visible and unscored.
