1// nx_parity_judge_gate.nx -- PROOF the ORGAN EYE classifies like the human did (the operator's bar:
2// "the workflow isnt complete until you [the Nishi team] see the exact same issues i see without your
3// or my involvement"). The truth set = REAL top-20 suite captures a human eyeballed on 2026-07-16:
4//   google  -> BLANK-NISHI (1)      blank render that fooled the parity metric at 97.3%
5//   bing    -> NO-ORACLE-CONTENT(5) headless Chrome itself served blank
6//   wikipedia -> CONTENT-OK (0)     the best real render
7//   github  -> CANVAS-OFF (3)       white vs attribute-selector dark theme
8//   linkedin -> SPARSE-NISHI (4)    full text, missing decoration/columns
9//   netflix -> BLANK-NISHI (1)      near-black + a hairline strip (human said STRIP; blank accepted as
10//                                   the honest coarser read -- the strip class needs >=2pm ink)
11// Fixture volatility: paths point at bench/top20 (regenerated by every suite run); if a site's live page
12// changes class legitimately, re-pin WITH an eyeball. license_tier: ORIGINAL  expect_exit: 0
