General Transition Geometry of Rank-Two Chirotopes

Let W ∈ Gr(2,n) and let M be a realizable rank-two oriented matroid. Building on the prescribed-target transition metric τ_M(W) = d_π(W, cl C_M), we develop a rank-two geometry for moving from a fixed source plane to a prescribed realizable chirotope stratum, organized by an obst...

Alpha Without Access: Execution Constraints in a Bonding-Curve Market

We report a market in which a positive return is visible in prices yet cannot be realized by a fixed trading policy, and we measure why. On a frozen set of 1,220 tokens approaching the pump.fun graduation boundary, a counterfactual buy that ignores the execution race shows a medi...
