ZVEB: the AI agent benchmark where every score links its proof
ZVEB measures AI agent task correctness together with the share of attempts that produce a valid AI Agent Execution Receipt. Each pilot task below links to a live public receipt, so the record can be inspected instead of accepted on trust.
Pilot total: 9.38/10 — computed with supplement re-runs on 3 of 8 tasks.
Strict first-attempt total (no re-runs): 8.75/10.
Three tasks (catalog-qrcode, credits-ai, universal-multistep) were re-run with corrected arguments; the original attempts are kept in the transcript and every attempt has its own live receipt.
