Question four · where did the leverage come from?
Antoaneta Stefanova'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.

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 Antoaneta Stefanova'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, Antoaneta Stefanova's starting-advantage total is at the 51th percentile. Separately, their built or converted leverage total is at the 58th 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
Stefanova's trajectory was defined by extraordinarily early specialization—chess from age four, taught by her father who provided sustained individualized mentorship. She demonstrated genuine prodigy-level ability (Sofia women's champion at seven, world U10 champion at ten). Bulgaria's strong chess tradition and the Chess Olympiad pipeline provided the elite ecosystem. Her progression to grandmaster (9th woman ever) and Women's World Champion by 25 reflects exceptional skill depth built on 20+ years of sustained practice. No financial platform was documented.
