about

nx_mmap_shared_gate.nx -- proves sys_mmap_shared gives ONE region across fork() (the foundation for the fork-per-connection video relay). Positive: a child's write into a shared region is visible to the parent. Neg-control: a private (sys_mmap) region is NOT shared (parent keeps its own copy). No false-green. license_tier: ORIGINAL
