The Preservation Gap in AI Stacks: Why Capability Progress Outpaces Reconstructability

O'Reilly Radar article proposes AI systems have"Save gap": Runtime dependencies (model endpoints, retrieval data, policies, tool contracts, etc.) are determined only at execution time. Existing infrastructure stores only models, code, deployments, and observability records, not the actual binding relationships for a specific execution. To address this, the authors propose the Orrery reference architecture, which preserves runtime bindings and dependency states needed to reconstruct the historical execution of AI systems, distinguishing between..."Reproducibility"And"Reconstructability"Two concepts.
