Question four · where did the leverage come from?
José Valim's leverage provenance
Each non-zero lever gets a best-supported origin, evidence signals, and confidence. Unresolved is the honest default when the biography cannot distinguish self-built, advantage-enabled, earned, external, or mixed.

This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of José Valim's outcome attributable to any origin.
Luck is not a leftover score.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 Founders / operators, José Valim's starting-advantage total is at the 23th percentile. Separately, their built or converted leverage total is at the 82th percentile. Other T2 profiles average 7.9 / 24 starting advantage and 12.3 / 25 leverage. Similar scores appear in other tiers, so these figures describe positioning—not a cause.

Evidence summary
Valim's by-26 milestone is co-founding Plataformatec and reaching Rails Core by ~25, proving scarce technical depth. Elixir (public ~2012) slightly straddles/after 26 depending on exact birthdate but the Rails/consultancy breakout is solidly ≤26. Open-source community compounding is the primary advantage engine.
