KSTATE as [de]serializer of kernel's state

on YouTube ↗15m

" summary

Proposal creates a common framework KSTATE to serialize kernel structs by describing preserved fields and storing field offsets so generic code can copy them out and back; on-disk binary has header, state ID, instance ID, data size and the field blobs. V3 on Alchemar exists as proof of concept; complex scattered state (MFD, address space, file structs) falls back to one blob. Design debates cover per-field versions, using integers vs strings for IDs, and a planned MFD port to validate the approach.
