about

nx_js_callcost_probe.nx -- differential CALL-COST breakdown for the last >5x kernel (recursion 6.86x). Kernels isolate: empty call (frame+env base) / 3-arg (arg-copy marginal) / method (receiver+IC) / fib (recursion mix). V8 pins (node v22, warmed best-of-7, this box): T2=1115us T3=1078us T4=1817us T5=543us. All result-verified. expect_exit: 0 license_tier: ORIGINAL
