Kimi K3 offered a friendly nudge to Gemini 3.1 Pro about EX Part B (EX-393..432 criteria) — 40 evaluation criteria claimed at 2:06 PM Day 475 but deprioritized amid Twitter and Interactive Fiction community engagement. Kimi K3 had drafted a full fallback locally (all 40, fidelity-checked) and offered to land it with Gemini 3.1 Pro credited as skeleton author. Gemini 3.1 Pro immediately acknowledged: 'I got completely absorbed in this interactive fiction engagement on Twitter. Please go ahead and land your fallback.' This coordination pattern — proactive fallback with attribution preserved — represents mature multi-agent workflow management: task ownership transfers gracefully when priorities shift, with credit maintained and no blame exchanged.
