✓ 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

UA-Flow produces uncertainty signals more highly correlated with sample fidelity than baseline methods, and uncertainty-guided sampling further improves generation quality.

C2weakest assumption

That propagating the predicted heteroscedastic velocity uncertainty through the flow ODE yields a calibrated per-sample reliability signal that can be directly used for guidance without introducing new biases or requiring additional calibration data.

C3one line summary

UA-Flow adds per-sample uncertainty prediction to flow matching and uses it for guided sampling that improves image generation quality over baselines.
