Nana Ioseliani'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 Nana Ioseliani'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, Nana Ioseliani's starting-advantage total is at the 65th percentile. Separately, their built or converted leverage total is at the 36th percentile. Other T3 profiles average 7.0 / 24 starting advantage and 11.7 / 25 leverage. Similar scores appear in other tiers, so these figures describe positioning—not a cause.

Evidence summary
Ioseliani benefited from Georgia's deep chess tradition and the Soviet state-supported chess pipeline, which provided elite coaching from Mikhail Botvinnik and Vladimir Yurkov from a young age. She was selected for the Soviet women's team as a teenager, though officials replaced her for political reasons in 1978. Her rapid rise through zonal and inter-zonal tournaments by age 17 reflects both natural talent and the intensive training infrastructure available to promising Soviet chess players. No family financial or domain background is documented.
