about

nx_reftest_gate.nx -- the VALIDATION SPINE: a sovereign WPT-style REFTEST runner + its gate. A reftest renders a TEST page and a REFERENCE page that the SPEC says must look identical (via different CSS mechanisms), then PIXEL-COMPARES the two renders: 0 diff => the engine is spec-consistent => PASS. This is the externally-defined conformance mechanism WPT itself uses for CSS/layout (the half that needs no JS). Seeded here with spec-equivalent pairs (tag==class selector; margin-left == padding-on-wrapper offset); REAL WPT reftest .html files drop into the SAME `reftest()` runner. A deliberate MISMATCH pair (blue vs red) is the LIAR-KILL: the comparator must report them DIFFERENT, proving it has teeth. The pass-% is the WPT-style metric. 100% sovereign (no Chrome/headless/gcc). license_tier: ORIGINAL
