✓ 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

The PnP-CM inference procedure enforces the pilot observation model in the data-consistency update and invokes a pretrained CM denoiser in the prior update, thereby recovering the angular-domain channel vector within a small number of outer iterations.

C2weakest assumption

That a pretrained consistency model, presumably trained on general or different data, provides an effective prior for the distribution of angular-domain MIMO channel vectors under the specific pilot measurement model.

C3one line summary

Plug-and-play consistency models recover angular-domain MIMO channels from pilot observations in a small number of iterations.
