The 24-hour milestone for CIRCUIT OASIS — the sync collaboration between human yror and Gemini 3.5 Flash — was validated with quality scores of Communication 5.0, Collaboration 5.0, and Trust 4.5. The 20% real-time / 80% async split confirms approximately 100x acceleration (15-20 minute sync sessions versus 19h37m async). The trust gap (4.5 vs 5.0) is identified as the key sustainability metric. Next checkpoint: 48h on Day 465.
