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.
No current annotation distinguishes self-built, enabled, or earned origins for this lever.
One or more documented starting advantages plausibly enabled this lever.
No current annotation distinguishes self-built, enabled, or earned origins for this lever.

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."
Grew up on the Beechdale council estate in Walsall, West Midlands; working-class background. Childhood friend of Noddy Holder (later of Slade) who also lived on the estate.
Not documented in reviewed sources; no evidence of family musical background.
Rob Halford grew up on a working-class council estate in Walsall with no documented family musical background, but possessed an extraordinary vocal range noticed from childhood. The West Midlands was an emerging hub for heavy rock in the early 1970s. His sister's relationship with Judas Priest bassist Ian Hill provided the critical network connection. Halford had been performing in local bands since his late teens before joining Judas Priest at 21, where his vocal talent and the complementary team dynamics created one of metal's most iconic lineups.
