Question four · where did the leverage come from?

Johan Hastad'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.

Structural wave / timing1/3

Externalmedium confidence

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 Johan Hastad'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 Researchers / independent engineers, Johan Hastad's starting-advantage total is at the 41th percentile. Separately, their built or converted leverage total is at the 72th 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.
