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

With this combination, the method achieves an AUC of 0.752, precision 0.81, and recall 0.61, a 35% improvement over the autoencoder alone.

C2weakest assumption

The synthetic LISA data sets used for training and testing, including the modeled confusion background and injected sources, sufficiently resemble the actual data LISA will record so that performance on these simulations predicts performance on flight data.

C3one line summary

A CNN autoencoder plus manifold normalization in latent space detects injected sources in synthetic LISA confusion data with AUC 0.752, precision 0.81 and recall 0.61, a 35% gain over autoencoder error alone.
