/*
 * 文件定位：Agent 运行态实现层 / 模型适配运行态绑定面。
 * 核心目的：承载 provider Carrier Registry 这一能力位点。
 * 能力要求1：需要把文件名表达的能力落实成清晰的类型、输入输出和最小行为。
 * 能力要求2：如果后续发现语义不足，应优先补接口契约，而不是把逻辑散落到相邻文件。
 * 边界：承托和治理运行态，不吞并执行引擎、模型适配器或官方模块内部实现。
 * 对接：需要服务 applicationSurface、officialModuleSurface、governancePlane、invocationMethod 和 inspection/debug 等运行面。
 * 实现提示：先补稳定类型契约、最小可测行为和清晰错误边界，再接入真实执行逻辑。
