Where the conditions came from
Each is placed on a −1 to 3 scale from documented evidence, and the three are never added together. A combined total would rank Kateryna Lagno 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: High. 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.
What moved through the conditions
This records repeated behaviour or recovery described by sources; it is not a grit or merit score.
A successful-only archive cannot recover all encounters, avoided setbacks, or alternative outcomes.
Strongest documented signals: Elite institution pipeline, Dedicated mentor / coach, Exceptional peer / cofounder.
Describes the starting position, not what the person later made of it.
Strongest observed levers: Prior reps, Scarce skill depth, Concentration intensity.
Measures what was present, not whether it was inherited, earned, self-built, external, or mixed.
The timeline below shows the sequence of work and transitions around the selected early milestone. It is evidence of a path, not proof that every step was necessary.
Dominant figure at the top of a field. The tier summarizes documented career recognition through the data cutoff—not Kateryna Lagno's worth or future potential.
Question four · where did the leverage come from?
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.
One or more documented starting advantages plausibly enabled this lever.

This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Kateryna Lagno'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.
Multiplying capacity documented later in the path. Measures what was present, not whether it was inherited, earned, self-built, external, or mixed.
Access or conditions documented near the beginning of the path. Zero means "no clear evidence in reviewed sources," not "advantage was absent."
Lagno was born in Lviv, Ukraine. She is described as 'half-Russian' and speaks Russian. Her family supported her chess development from a very early age, enrolling her in the prestigious Kramatorsk chess school. The Ukrainian/Soviet chess infrastructure provided elite training opportunities. Her early start at age 2 suggests highly involved parents who recognized and nurtured her talent.
Not documented.
Lagno's enrollment in the Kramatorsk chess school alongside Ponomariov and Karjakin demonstrates elite pipeline access. Breaking Polgár's WGM record at 12 is clear prodigy evidence. Learning chess at age 2 and becoming national champion at 7 shows extreme early specialization with family support. The Soviet/Ukrainian chess system provided structured competitive development from childhood.
