nx_nishios_browser.nx -- BROWSER-ON-ALL-OS arc, rung N1: the Nishi browser renders ON NishiOS. Operator (2026-07-02): "finish getting our nishi browser to s class exceed on all OSs including our future nishi os." The browser already runs on Linux (nx_browser, X11/WSLg) and native Windows (nishi.exe PE). This rung puts the SAME OS-agnostic render core (nx_browser_render: br_layout -> CSS cascade -> box layout -> br_draw_fb paint) onto NISHIOS: it boots the persisted NishiOS image on the sovereign x86 emu (same unified boot-disk emu proven in nx_nishi_usb_longmode/_desktop), and ONLY because the disk-loaded kernel reached LONG mode does the browser render a real HTML page and composite it into the NishiOS desktop framebuffer (nx_fb). Export = knowledge/status/ nishios_browser.bmp + .html = one picture of "boot NishiOS -> open the Nishi browser". KAT: T1 booted off the persisted image (INT 13h: 0x8000 0->0xBE); T2 disk-loaded kernel reached LONG mode (mode==2); T3 UART banner == 'NishiOS'; T4 REAL layout (page.ok, box count, page height); T5 h1 background bar pixels present in the composited desktop; T6 link-blue pixels present; T7 body-text pixels present; T8 BMP exported at the exact expected size. NEG/liar-kill: T9 a 0-sector-load sibling image never reaches long mode -> the browser gate never fires (window region of a fresh desktop stays zero); T10 a tampered EMPTY page collapses the box count below the T4 threshold (the layout evidence is content-sensitive, not a constant). HONEST SEAM (no overclaim, same as every nx_nishi_usb_* rung): the emu EXECUTES the MBR loader + real->protected->long CR0/EFER transition as real x86 off the on-disk bytes; the browser render then runs in NishiLang (the same sovereign language the kernel compiles from) as the OS's app layer, painting the nx_fb framebuffer. Running the render loop itself as x86-on-emu, NishiOS-native networking (fetch on-OS), and live input are the next rungs (N2/N3) -- named, not claimed. NEVER-BRICK (Rule 26): writes FILE artifacts only (.img/.bmp/.html); models INT 13h *reads*; no /dev. expect_exit: 0 license_tier: ORIGINAL
