nx_js_sota_scorecard.nx

nx_js_sota_scorecard.nx -- HONEST placement of the sovereign Nishi JS engine vs the 2026 SOTA engines (V8, JavaScriptCore/WebKit, SpiderMonkey) and the honest interpreter-class peer (QuickJS). This is an ARCHITECTURAL scorecard, NOT a benchmarked head-to-head: we CANNOT run JetStream2/Speedometer3 (they need a full browser + complete language + WASM + workers), and every speedup we've measured is vs OUR OWN tree-walker, NOT vs V8 -- so this card states tiers/features honestly and names what we have not measured. Competitor levels are GROUNDED in the sovereign research corpus knowledge/fetched/jsvm_*.raw (v8.dev Sparkplug/Maglev/TurboFan/Ignition, JavaScriptCore FTL/B3, SpiderMonkey Warp/Ion, JetStream). Our levels are GROUNDED in our own measured gates (parity 110/110, conf 74/74, jit 49/49, shape 8/8, poly 3/3, realbench 5/5, consumer-swap 17/17). Level scale: 0 NONE, 1 PARTIAL, 2 HAVE, 3 MATURE/HARDENED. A LIAR-KILL asserts the card must NOT rate us at-or-above SOTA overall (we are behind) -- if it ever does, the numbers were gamed and the gate goes RED. expect_exit: 0 license_tier: ORIGINAL
