1 Mandatory gates — any Fail or Pending makes the candidate ineligible, whatever the score

Record evidence confidence: A Verified · B Substantiated · C Claimed · D Unknown. A gate with D evidence counts as not demonstrated.

2 Weighted scoring matrix — contribution = weight × (score − 1) ÷ 4

Score each category 1–5 against a measurable requirement. Set a floor where a minimum is mandatory — a score below the floor flags a critical weakness even if the total looks good.
