Skills advance through evidence — not declaration. Each rank unlocks the next.
A skill earns its Overall Trust Grade by the strength of the evidence behind it. Four tiers — Bronze, Silver, Gold, Platinum — mark the aggregate Trust Magnitude that a skill's evidence pool reaches.
Each piece of evidence (a repo, a benchmark, a peer-reviewed paper) earns its own per-row Evidence Grade. The numbers above are the aggregate Trust Magnitude thresholds the rows must combine to clear. See the methodology report for the full formula.
