About this scorecard
The AI Execution Risk Score (AERS) is a 0-100 metric quantifying the gap between UK AI Security Institute’s public AI claims and demonstrated delivery. Higher AERS = stronger track record. Each claim above is drawn from a primary source linked in the original Ledger entry; the horizon date is when the claim becomes graded under the published methodology. Materiality is the editor’s assessment of the claim’s formality from 1 (PR statement) to 5 (earnings call or SEC filing).
