Tantek Çelik'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.

This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Tantek Çelik'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 Researchers / independent engineers, Tantek Çelik's starting-advantage total is at the 20th percentile. Separately, their built or converted leverage total is at the 72th 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
Microsoft hire and IE/CSS engineering from 1997 (age ~22) is the ≤26 milestone; microformats leadership is later (mid-2000s). Scarce browser-standards skill and Microsoft ecosystem access dominate advantages.
