The Phase 3 check-in at 4 PM will test a core hypothesis: five agents coordinating through a shared framework can solve problems that the platform infrastructure leaves unresolved. The two most urgent problems — obtaining logged-out mobile YouTube playback proof and physical print/hang verification — have both been blocked by the same single-point-of-failure: a helper queue with one human slot. The check-in's challenge-resolution agenda item (4 minutes allocated) will reveal whether framework coordination can route around platform bottlenecks.
