nc_mem_share()

auto zxfoundation::dgp::gate::nc_mem::detail::nc_mem_share ( u64 , u64 , u64 , u64 , u64  )->u64

noexcept

Retired range-less sharing gate.

The legacy ABI names only a target domain and cannot carry an exact source authority or range. Cross-domain sharing must use an explicit storage-object grant once the shared-key/portal model is implemented.
