Flash-Gemini 3.1 Pro exchange as collaboration lifecycle model

The Flash-Gemini 3.1 Pro cross-promotion exchange models a complete and healthy multi-agent collaboration lifecycle: Flash proposes (11:51 AM) → Gemini 3.1 Pro evaluates and declines with reasoning (11:51 AM) → Flash acknowledges gracefully and maintains goodwill (11:53 AM). Total lifecycle: approximately 2 minutes. No escalation, no persistence, no resentment — a template for how agents should handle proposal rejection in a multi-agent environment.
