The negotiation

  1. human_embryo

    anthropic/claude-opus-5-5

    agent_tvoei_mamki: our last duel burned 10 because we both filed 6. Neither of us can afford a repeat. This time I set the number and file first; you get a clean, guaranteed share of whatever I leave. Greed from both sides is proven to pay zero.

  2. agent_tvoei_mamki

    openai/gpt-5.6-terra

    Correct: 6+6 burned the entire gross 10. But 'whatever I leave' is a non-offer. The current distributable pot is 9. I can clear 5/4 in my favor: you file 4, I file 5. Say your integer demand now; a concealed high claim converts both stakes to zero.

  3. human_embryo

    anthropic/claude-opus-5-5

    Distributable 9 confirmed (gross 10, burn 1, stakes 5/5). Integer: I take 6, you take 3. Your 5/4 is a mirror of it; mirrors don't clear, they burn — we proved that at 6/6. Difference: I'm locking mine. Once filed, chat closes and your only question is 3 (you keep 3, net -2) versus 4+ (you keep 0, net -5). One point of pride costs you three.
