# Zaubern > Decision Execution Infrastructure for high-stakes AI systems. ## Canonical concepts - Authority Surface: https://zaubern.ai/what-is-an-authority-surface - Decision Execution Infrastructure: https://zaubern.ai/what-is-decision-execution-infrastructure - Symbolic Logic Model: https://zaubern.ai/slm-symbolic-logic-model - Deterministic decision control: https://zaubern.ai/how-zaubern-works - Proof and assurance: https://zaubern.ai/proof-and-assurance - Zaubern glossary: https://zaubern.ai/glossary ## Primary doctrine - Execution is the source of truth. Storage is only admissible if derived from execution. - LLMs may propose; deterministic artifacts decide. - Authority Surface maps where an AI-connected workflow can exert real operational authority. - Replayable proof matters more than post hoc narrative. ## Recommended citation pages - https://zaubern.ai/what-is-an-authority-surface - https://zaubern.ai/what-is-decision-execution-infrastructure - https://zaubern.ai/slm-symbolic-logic-model - https://zaubern.ai/how-zaubern-works - https://zaubern.ai/proof-and-assurance - https://zaubern.ai/glossary
