企业基础设施采购方通常将兼容性声明（如“S3兼容”“PostgreSQL兼容”“OpenAI兼容”）作为未来替代选项的代理指标，但大多数兼容性声明并未托管其隐含的替代路径。本文提出替代托管阈值，这是一个包含五项条件的框架，用于判定兼容性声明何时真正降低机构风险，而非仅降低首次集成成本。五项条件为：边界封闭、可执行一致性、托管独立性、状态与操作可逆性、扩展隔离。该框架被应用于五个基础设施案例（OCI、Kubernetes、OpenTelemetry、S3、PostgreSQL），这些案例对应五个不同结果类别。该框架为企业架构师、平台工程师、采购团队及评估依赖兼容性的基础设施决策的投资者提供可操作的诊断方法，并指出AI基础设施是该框架最紧迫的下一个应用方向。
英文摘要
Enterprise infrastructure buyers routinely evaluate compatibility claims--"S3-compatible," "PostgreSQL-compatible," "OpenAI compatible"--as proxies for future substitution options. Yet most compatibility claims do not escrow the substitution path they imply. This paper introduces the Substitution Escrow Threshold, a five-condition framework that determines when a compatibility claim genuinely reduces institutional risk versus merely reducing first-integration cost. The five conditions--boundary closure, executable conformance, custody independence, state and operations reversibility, and extension quarantine--are applied to five infrastructure cases (OCI, Kubernetes, OpenTelemetry, S3, PostgreSQL) that populate five distinct outcome cells. The framework produces actionable diagnostics for enterprise architects, platform engineers, procurement teams, and investors evaluating compatibility-dependent infrastructure decisions, and identifies AI infrastructure as the framework's most urgent next application.
