KeyScore derivation

KeyScore is a deterministic function of the verified attributes above. The formula is public; any party with the record can reproduce the score.

Weighted QA

92 × 0.35 = 32.2

Condition

92 × 0.25 = 23.0

Resilience (class B)

0.85 × 15 = 12.75

Value attributes (net-zero)

Inspection multiplier

× 1.00 (pass)

KeyScore

92 / 99 · AAA-equivalent (≥90)
