Abstract: A computer-implemented adaptive contamination-resistant benchmarking system (100) for artificial intelligence models comprises a dynamic item generation engine (110) synthesising evaluation items from parametric templates under expert-calibrated constraints; a cryptographic item vault (120) operating within a trusted execution environment (121) that stores live items in encrypted form and releases them solely to an ephemeral scoring channel (172); an expert calibration interface (130) aggregating reputation-weighted judgment from credentialed evaluators; a contamination detection unit (140) applying canary tokens, semantic fingerprints, and perplexity anomaly analysis; a signal validity analyzer (150) computing item response theoretic discrimination indices; a model evaluation orchestrator (170) mediating evaluated-model access through a secure application programming interface gateway (171); a procedural transparency ledger (180) recording tamper-evident governance metadata without disclosing item content; a
