Frontier geography (1/2)
This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Iker Casillas'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.
Within Athletes, Iker Casillas's starting-advantage total is at the 65th percentile. Separately, their built or converted leverage total is at the 80th percentile.

Evidence summary
Casillas joined Real Madrid's academy at 9 and spent 10 years in the youth system before debuting for the first team at 18. His working-class parents (civil servant and hairdresser) had no football connections, but Real Madrid's elite academy provided world-class facilities, coaching, and a pathway to the first team. He won the Champions League at 19, the youngest goalkeeper to do so. The institutional pipeline of Real Madrid was the dominant early advantage, providing domain proximity and elite peer exposure from childhood.
