1// nx_reader_exceed_gate.nx -- MEASURED exceed scorecard for the Nishi reader (no-wave, organ-graded, never
2// self-scored). Mirrors the nx_pub_exceed_gate / nx_ws_exceed_gate doctrine: MECHANICALLY measure the Nishi side
3// (read reader.html + a real book.json), name the incumbents as documented yardsticks (Kindle/Calibre-Web/foliate
4// -- by-design, NOT run/fabricated, cited in knowledge/fetched/reader_*.raw), and grade each axis EXCEEDS / PARITY
5// / BEHIND. EXCEEDS is allowed ONLY on a win-eligible axis whose mechanical measurement passed; a LIAR-KILL refuses
6// EXCEEDS on a behind-axis or an unmeasured axis. GREEN = an honest measured scorecard + intact liar-kill, NOT
7// "we beat everyone". Self-contained + sovereign (fork/exec, no shell).  expect_exit: 0
