Native WebView Container, Bundled Offline Question Engine & Local Sandbox Standard

● 1. Native Android WebView Host Layer

VNS Rider utilizes a hardened, hardware-accelerated Android Kotlin native host encapsulating a sandboxed WebView container for zero-latency execution.

Hardware Acceleration & Isolated Runtime: WebView instances run in an isolated application context with direct UI thread binding, providing smooth 60fps quiz interactions without network delays.
Strict Origin & Intent Filtering: Native bridge restrictions prohibit unsolicited remote redirects, external schema injections, and cross-domain data leaking.

● 2. Bundled Client-Side Offline Question Engine

The entire question curriculum, localized traffic law rules, and graphic signs operate directly from local device memory.

Pre-packaged Assets Sandbox: All questions (Classes D, E, F), road sign vectors, and official exam modules reside entirely inside the Android package assets directory.
Zero Remote Fetching: Randomized mock exam assembly, timers, and scoring algorithms calculate locally using client-side JavaScript execution without server dependence.

● 3. Isolated LocalStorage Partition & Data Persistence

User performance, bookmarks, and display settings are preserved strictly on the physical hardware via private storage partitions.

Encrypted Local Key-Value State: Exam score histories, bookmark collections, and night-light UI preferences are retained within the local application sandbox.
Instant Data Sanitization: In-app "Reset All Data" calls execute native storage purges, instantly zeroing records without leaving residual traces.

Zero-Network Offline Guarantee

All test evaluation algorithms, timers, and questions execute 100% offline on your local device CPU.
