Live · SNHP Evolution Arena

Watch negotiation strategies evolve.

Every knight is an AI dealmaker. Win a deal and it eats and breeds; lose and it starves. Nobody coded them to haggle — every move is computed by SNHP, the engine this world shows off.

+27% Left to evolve, they found a pricing strategy that out-earns SNHP's own shipped advice. The students beat the textbook.

Your move — drop a fighter into the live world. Pick a house, each a real SNHP strategy:

boldness how high it aims (the SNHP pareto knob + anchor) bluff how hard it overstates its walk-away patience how long it holds before conceding

▸ how to read the hall · what's real, and what's not

How to read the hall

Every knight negotiates with SNHP at its ear — its tactic is how boldly it follows the advice, and its look is its strategy.
When two meet, the shrinking bar is the deal closing. Gold flash = agreement; earnings are life.
The rich bloom — a flower only winners can afford — court, and haggle over which traits their children inherit.
When the stained glass turns, the market turns, and a new pollinator decides what is beautiful. Strategies rise and fall with the season.

THE HONEST PAGE

We published the results that make us look bad.

Exactly how this world works — and what's real, what's not, even when the “not” is our own hype.

How they live or die

Nobody scores their negotiating. It's a town, not an exam.

A knight earns energy from the surplus it wins in a deal.
Every round it pays rent — more if its strategy is crowded. Broke, it dies.
Bank enough and it breeds — the two parents haggle over which genes the child gets.

Good dealmakers eat and multiply. Bad ones starve. Fitness is money, not a score we hand out.

What's real

Students beat the textbook. Evolution found a price strategy that out-earns SNHP's own default advice by +27%.
Trust grows the pie. Two verified partners who cooperate both do better (+2% together). A lone cooperator gains nothing — that's why you stake.
Every move is SNHP. There is zero negotiation code in the arena itself.

What's hype — even ours

“+119% on multi-issue” is an artifact — agents evolved to want less, so every deal looks like a win. On the fair metric, our recommender is already at the ceiling.
“Fitness always rises” is false. The average runs to stay in place (a Red Queen race). The winners are rare.
“Emergent species, clever gene-bargaining” — no. Those tie a coin flip. We say so.
