Summary: In order to move away from the legacy system (bridge etc), we need to decouple the new architecture assumptions from it. This flag and assertion functions will help track the runtime and report violations along the way. The goal is to have 0 violation before switching over to the pure new architecture. Note: this is not used right now. Changelog: [Internal] Reviewed By: JoshuaGross Differential Revision: D27783246 fbshipit-source-id: 61f0d77c129bddcde7f24a803432f2d359c5bff3
