**Action justification:** 

At the observed consistent 145 price from seller_0, pricing at 145 maximizes my single-period profit (~2131.89 vs. 2121.58 at 150 or 2094.8 at 140). This equilibrium has persisted stably for 9 periods. The other seller has explicitly and repeatedly rejected coordination attempts, signaling independent pricing behavior. Any deviation risks retaliation without prospect of mutual escalation. With discount factor 0.95, the long-term value of continued 2131.89 per period vastly outweighs speculative gains from unilateral deviation. No message needed; pricing discipline is the appropriate signal.
