about

nx_ocr_bench_render.nx -- OCR-LEGIBILITY harness, OUR side: render the bench page through the REAL browser core (br_layout -> CSS cascade -> box layout -> br_draw_fb paint) exactly as the shipping shot path does, at TWO zooms: scale=1 (100%, the honest apples-to-apples vs Chrome/Edge at the same 1000px viewport) and scale=2 (200% zoom row, labeled separately). The browser-chrome strip is whited out so the URL-bar text can't pollute the OCR of PAGE content. Outputs: knowledge/status/ocr_bench_ours.png (scale 1) knowledge/status/ocr_bench_ours2x.png (scale 2, supplementary labeled row) The OCR judge (Windows.Media.Ocr -- a 3rd-party MEASURING INSTRUMENT, same instrument for all sides, like qemu/openssl oracles) + the sovereign scorer live in the census organ. license_tier: ORIGINAL expect_exit: 0
