Trustworthy AI characteristics
Per NIST AI RMF §1.2.5 — 0=not addressed, 5=monitored
Risk inputs
Tier formula: impact × likelihood × (6 − reversibility). ≥ 50 → Tier 1, ≥ 18 → Tier 2, else Tier 3.
Severity if the system fails or is misused (1=trivial, 5=existential).
Probability of exposure given current usage cadence.
Ease of unwinding a bad output (5=fully reversible, 1=irreversible).
Required controls — 3 for Tier 3 (low)
