Entities in the same semantic neighborhood but without a typed relation to this one — candidates for new edges or unrecognized duplicates.

• G2.5-FL cost per quartet 1,193 coinsfinding0.811
  Much higher cost per quartet due to waste.
• Gemini 2.5 Flash Lite pays 1,193 coins per quartetfinding0.761
  G2.5-FL's cost per quartet is nearly double that of efficient agents.
• Gemini 3 Flash completes fourth quartet by paying far above face value, netting ≈1,800 points from multiplicative scoringfinding0.715
  A trace shows G3-F turning a nominally wasteful overpay into a net score gain due to the multiplicative formula.
• Claude Haiku 4.5 and EconomyAgent average fewer than 1.7 quartets per gamefinding0.700
  Weak agents complete very few quartets, correlating with low scores.
• Within-agent spread across seven evolvers is at most 5.1 pp (Qwen3-235B on MCP), small against the 36.0 pp gap between Opus and Qwen3-235B base capabilitiesfinding0.686
  Demonstrates that post-evolution score is dominated by agent base capability, not evolver identity
• The three code agents never overbidfinding0.675
  Deterministic heuristics avoid the overbidding failure mode entirely.
• A naive agent equipped with reduced priors from an experienced agent performs perfectly with maximum confidence from the first trial.finding0.664
  Demonstration that model-level priors (not parameter-level knowledge) suffice for immediate transfer
• G3-F averages 3.96 quartets per gamefinding0.656
  high quartet completion rate
