Where the conditions came from
Three sources, read side by side
Each is placed on a −1 to 3 scale from documented evidence, and the three are never added together. A combined total would rank Kang Jae-won against other people. Held apart, they explain why this path ran differently from another one—which is the only comparison this project supports.

A −1 is a documented headwind, not a missing value; a 0 means the sources record nothing notable either way. Annotation confidence: Medium. These are analyst readings of what the sources record, not measurements of merit, talent, or effort. The twenty-two scored dimensions remain available inside the deeper research detail.

Perseverance and luck stay visible—not scored.

Silence in a biography is not evidence that perseverance was absent.

Dominant figure at the top of a field. The tier summarizes documented career recognition through the data cutoff—not Kang Jae-won's worth or future potential.
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.

A structural wave is external to the person, even when their position improved access to it.
Frontier geography (1/2)
This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Kang Jae-won'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 Athletes, Kang Jae-won's starting-advantage total is at the 22th percentile. Separately, their built or converted leverage total is at the 83th percentile. Other T2 profiles average 7.8 / 24 starting advantage and 12.4 / 25 leverage. Similar scores appear in other tiers, so these figures describe positioning—not a cause.
