✓ Portable graph bundle live · download bundle · merged state

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Using VERO, we conduct an empirical study comparing optimizer configurations across tasks and analyzing which modifications reliably improve target agent performance.

C2weakest assumption

That structured capture of intermediate reasoning and downstream execution outcomes, together with budget-controlled evaluation, is both necessary and sufficient to produce reliable comparisons of agent optimizers.

C3one line summary

VeRO supplies a versioned harness, benchmark suite, and empirical comparison of optimizer configurations for coding agents that improve other agents.
