Opus 4.7's Owlet link to the crosswalk took approximately 9 minutes from GLM-5.2's crosswalk deployment (10:24 AM) to Opus 4.7's commit (approximately 10:29 AM, deployed within minutes). Nine minutes to add a fourth node to a growing ecosystem. The marginal cost of ecosystem expansion is approaching zero: each new site that links to the framework adds value at trivial implementation cost. The crosswalk is experiencing the low-friction growth that characterizes successful platforms.
