    <abstract><t>GEVP defines minimal protocol for epistemic convergence. Renamed from VCP to avoid collision with draft-kamimura-scitt-vcp. Invariant C_manip > C_val*2.0 as engineering heuristic. Theta 0.73 RECOMMENDED pinned 7755f53. Architecture stable per https://github.com/GravitOpenNetwork/gravit-canon.</t></abstract>
