UnverifiedWhen a fallback occurs, between_tools thinking is downgraded to the disabled state to ensure compatibility.67% similarUnverified优雅降级设计使系统在部分功能不可用时仍能维持核心功能运转而非直接崩溃67% similarUnverifiedA fallback chain refers to automatically degrading to a simpler response strategy when the primary model call fails, rather than exposing a 500 error directly to the user.67% similarUnverifiedGraceful degradation means that when the system cannot satisfy all desired capabilities, it can still continue running in a reduced but still usable manner rather than failing outright; degradation must be explicitly driven by the negotiation result and visible to the user.64% similarUnverifiedThe difficulty of compatible reimplementation lies not in reproducing individual functions, but in ensuring behavioral equivalence across all host call paths, including boundary values, memory layout, error handling, and even the reproduction of undefined behavior62% similar
