guest-diag: content-validated delta emission for the CE push-buffer memHEADmaster
The one-shot CE mem emission pinned the whole 16 MB window including pages whose content was zero at the time; the host then read zeros for the other CE ranks' pushes. Sweep the mem every 2 s, skip zero pages, emit only new/changed {va,pa} pairs, and burst the Kcore PA cache every 30 s so a remap is re-emitted instead of shadowed by the cache.
