nx_maint_simpage.nx

nx_maint_simpage.nx -- the IN-BROWSER PROOF PAGE. Composes the closed-loop simulation + RUL prognosis + business case into ONE zero-JS, privacy-first HTML page that renders in the Nishi browser AND Chrome/Firefox/Edge -- the operator's vision: simulate + prove the whole business in software, in the browser, reproducibly, before a penny IRL. Operator (2026-06-23): "using software to simulate these things in our nishi browser and 3rd party browsers ... proven via all modeling of the business, legal, sensors, hardware." This is the capstone that makes the proof VIEWABLE. Reuses the nx_maint_render doctrine: 0 <script>, 0 third-party loads, fail-closed (nx_maint_render_is_clean). Cross-browser by construction (server-rendered, no JS). NEVER-BRICK (#26): builds bytes into a caller buffer; no syscalls, no writes. genealogy_id: project-maintenance-platform-sclass-2026-06-23 (in-browser proof page) license_tier: ORIGINAL
