GAME-HUBE-BILLIONAIRE-001. Owner: Alexander Romaskevich / RomaskevicH.\n\nLive build: https://milliarder-game.val.run/\n\nThis continues the existing M1. It is a playable browser prototype, **not a completed AAA game or a completed Dubai Full Alpha milestone**. The original M1 game engine is byte-for-byte unchanged and M1 remains selectable on the title screen. Prior M1 evidence is 15/15 LIVE_TESTED, reused from the existing project journal.\n\n## Play\n\nEnter Dubai, open Garage, buy Sahra Nova with fictional credits, close the panel, press V to enter the car. Open Opportunities and accept “Первая городская поставка”. Close the panel; use WASD/arrow keys or “Ехать по маршруту” to drive to the delivery point. Press E near the destination. The mission rewards 12,000 game credits once. C changes camera, Space brakes, M opens the map. Touch buttons are implemented; a real mobile-device playtest is still outstanding.\n\nSettings provide save, JSON export/import, weather and synthesized audio. Saves stay in the player's browser; there is no real-money payout, token integration, bank link or promised income. M1 migration writes a separate v2 save and retains the M1 save. Strict validation detects invalid structure/ranges; it is **not cryptographic anti-cheat** against a player editing their own valid single-player save.\n\n## Implemented scope\n\n- Deterministic 6,144 × 6,144 world-coordinate boundary with nine district regions; repeating procedural street grid and streaming geometry. This is a technical world extent, not a claim of a fully authored 37.75 km² city.\n- 12 original vehicle profiles, shared procedural visual chassis variants, purchase/selection and different acceleration/braking/grip/speed.\n- 18 residents with schedules, needs, memory and help effects; simplified ambient traffic.\n- 21 points of interest, including six businesses, seven properties and four traversal missions.\n- Simple interior/exterior mode, day/night, three weather states and optional synthesized audio.\n- WebGL renderer plus a tested Canvas perspective fallback. The test browser lacks WebGL2; the WebGL visuals remain unverified. Canvas measured 28 FPS in one browser observation with nine loaded chunks; this is not a cross-device performance guarantee.\n\n## Evidence\n\n22 Node simulation tests passed. Browser playtest: purchase → vehicle entry → mission acceptance → actual 387.5 m traversal → reward → reload → completed mission retained → export validation. After buying for 18,000 and earning the once-only 12,000 mission reward, the test save contains 94,000 **fictional game credits**. Screenshots and DOM records are under evidence/.\n\nRun tests with Node 24: `node --experimental-strip-types dubai_engine_tests.ts`.\nThe Val Town `run_file` call only imported the node:test suite and returned no harness output; it is not counted as a second PASS.\n\n## Contribution truth\n\n447 existing NCA IDs had 450 template artifacts generated by LOCAL_DETERMINISTIC_GAME_BUILDER. Their recorded content hashes match. They are archived as ARTIFACT_READY and receive **no professional implementation credit**. Existing TOBIYS/MORGAN/ROTHSCHILD direction informed this increment, with exact source references retained.\n\nNew implementation was produced by ASTRA and two actual session coding collaborators, /root/dubai_simulation and /root/dubai_renderer. They are not newly registered NCA and are not impersonations of the named fleet. GAME_CONTRIBUTION_LEDGER.json distinguishes their actual code, root integration/review and verification limits. Two session portfolios are verified for their tested scope; WebGL renderer portfolio remains INTEGRATED pending a GPU playtest. Registered autonomous NCA portfolio verification for new professional implementation: 0.\n\n## Scope still outstanding\n\nFull authored Dubai districts, sophisticated NPC traffic/pathfinding, unique detailed vehicle bodies/interiors, suspension and damage simulation, helicopters/yachts/aircraft driving, advanced business simulation, full accessibility/mobile QA, audio production, native-engine build, GPU profiling and release-candidate certification. M2 and M6 are not declared complete; M8 is not reached.\n\nNo paid infrastructure or paid model/API was purchased. RTK was not available on this local PATH; CODEBURN IMPERIAL was not connected in the inspected execution surface. Output was bounded and prior evidence reused without claiming these tools were installed.\n\n## Deployment and preservation\n\nSource targets existing Val Town project `oromaskevic23/milliarder-game`. `index.ts` serves the React app via the original Hono/immutable-file route. Deploy modules before updating App/root imports. No new project or domain is required. The baseline/ directory preserves the original six M1 source files retrieved before edits. No GitHub activity is fabricated; source commits are null where none exists.\n\nThree.js 0.180.0 uses its verified MIT license, retained under licenses/. New scenery, vehicle geometry and SVGs are procedural source code. Attached reference posters are not shipped as assets. Original model names are design names; global trademark clearance is not claimed.\n",[163],"ba45aebd-cdf4-4c35-9f88-9861103f4132","CHANGELOG.md","01a07db8-12e1-737f-8f4d-abf751b50929",["D",1788815610474],"# Changelog\n\n## 2026-07-30 — Immutable asset caching\n\nFrontend files are now served at version-addressed URLs\n(`/__immutable/45/frontend/index.tsx`) with\n`Cache-Control: public, max-age=31536000, immutable`, so repeat visits load the\nwhole client graph from the browser cache — roughly 3× faster (~665ms → ~157ms\nmeasured). Publishing your val bumps its version, which changes every URL, so\ncaches invalidate automatically. Old-version URLs return 404 after a publish\n(like Next.js build assets); a reload picks up the new version.\n\nWhat changed in the template:\n\n- `frontend/index.html` → [`frontend/root.tsx`](/frontend/root.tsx): the HTML\n shell is now JSX and stamps asset URLs with `immutableFileUrl()`\n- [`index.ts`](/index.ts): serves `Root()` at `/`, and one\n `app.get(\"/__immutable/*\", (c) => serveImmutableFile(c.req.path))` route\n serves all frontend files\n\n### Upgrading an existing remix\n\nYour copy of this template doesn't update automatically. Two options:\n\n**Minimal (most of the benefit):** point both routes at `serveImmutableFile` —\nyour existing bare URLs redirect into versioned space, the new route serves\nthem, and the whole module graph gets cached (costs one redirect per page view):\n\n```ts\nimport { serveImmutableFile } from \"https://esm.town/v/std/utils/index.ts\";\n\napp.get(\"/__immutable/*\", (c) => serveImmutableFile(c.req.path));\napp.get(\"/frontend/**/*\", (c) => serveImmutableFile(c.req.path)); // was serveFile\n```\n\n**Full upgrade (also removes the redirect):** three self-contained steps —\nno other files needed. Adjust the ``, favicon, and body of `Root()` to\nmatch your app's existing `index.html`, and stamp anything else your shell\nreferences directly (images, css) with `immutableFileUrl()`.\n\n1. Create `frontend/root.tsx`:\n\n```tsx\n/** @jsxImportSource npm:hono@4/jsx */\nimport { raw } from \"npm:hono@4/html\";\nimport { immutableFileUrl } from \"https://esm.town/v/std/utils/index.ts\";\n\n// The HTML shell for the app. It is never cached, so immutableFileUrl can stamp\n// the current val version into each asset URL — the browser caches those\n// immutably, and publishing the val changes the URLs, refetching exactly once.\nexport function Root() {\n return (\n <>\n {raw(\"<!DOCTYPE html>\")}\n <html lang=\"en\">\n <head>\n <meta charSet=\"UTF-8\" />\n <meta name=\"viewport\" content=\"width=device-width, initial-scale=1.0\" />\n <title>React Hono Val Town Starter\n
