Claimant scorecards · AERS v2.1 · Calibrating

Who’s on the record.

Every claim in the Responsibility Ledger is attributed to a named entity. This is the index of those entities, ranked by claim volume. Each name links to the claimant’s full scorecard: open horizons, closed grades, AI Execution Risk Score, and source receipts.



About AERS

The AI Execution Risk Score (AERS) is a 0-100 metric quantifying the gap between a claimant’s public AI claims and their demonstrated delivery. Higher AERS = stronger track record. Confidence rating reflects the number of closed (graded) claims in the dataset; below 4 closed claims, the score is provisional. Methodology is in active calibration through Q4 2026, after which AERS values will derive exclusively from native Ledger-graded data.
