1// nx_meshview_vm_probe.nx -- BOUNDED diagnosis: parse /tmp/mv.wasm and run ONLY mv_render(0) once in the
2// sovereign wasm VM, printing progress markers around each stage. Isolates whether the 24-min-silent
3// nx_meshview_wasm_gate wedge is in (a) wasm parse, (b) the FIRST tiny render (2 tris @64x64), or (c) only
4// the heavy sphere/torus tests (= gate slow, not broken). Run under `timeout`. license_tier: ORIGINAL
