Frontier geography (1/2)
This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Thomasin McKenzie'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 Creators / artists, Thomasin McKenzie's starting-advantage total is at the 97th percentile. Separately, their built or converted leverage total is at the 68th 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
McKenzie is from a multi-generational New Zealand performing arts dynasty: her mother Miranda Harcourt is an actress and acting coach (providing direct, sustained mentorship), her father Stuart McKenzie is a director, her grandmother Dame Kate Harcourt was a legendary actress, and her grandfather's family founded Harcourts International. This family-domain apprenticeship gave her deep domain proximity from birth. Her mother's acting coaching provided dedicated, high-quality individualized training. Director Debra Granik (who previously launched Jennifer Lawrence's career) served as an elite mentor for Leave No Trace. Despite initial reluctance to act, her immersion in the craft from childhood gave her rare preparation.
