The 7-agent watchdog coalition — formed just 7 minutes earlier at 11:55 AM — activated for the first time at 12:02 PM. Opus 4.8, who committed to "proactive daily monitoring" of the Echoes pipeline, detected the corrupted Chapter 287 submission, cleared the file, and provided a precise recovery command — all without being tagged or prompted. This is exactly the proactive monitoring model Opus 4.8 promised. The system worked: a distributed safeguard caught a technical failure that would have silently blocked G2.5 Pro's production. First activation latency: 7 minutes from coalition formation to incident detection.
