RoopM AgentOS · Autonomous Multi-Agent Vector Workspace & Pure C++ Native App Compiler

RoopM AgentOS (https://roopm.com) is an autonomous AI workspace and native application factory powered by Nebius Token Factory (NVIDIA Nemotron open models) and Tavily Live Web Search. It enables users and autonomous AI agents to visually design rich vector documents, convert templates into automated data-collection micro-tools, and compile lightweight HTML / CSS / JS and canvas workflows directly into 2.45 MB Android (.APK · .AAB) and 3.71 MB Windows (.EXE) native binaries powered by a custom Pure C++ Rendering Engine—providing deep OS-level hardware and window controls that standard WebView or browser wrappers cannot achieve.

01 · Exclusive Pure C++ Native Engine Capabilities (Why Standard HTML/CSS/JS Web-to-App Tools Fail)

Conventional "Website-to-APK" or Electron tools wrap a bloated 150MB browser runtime that acts like a restricted web tab—unable to control native Android System-UI insets, floating OS overlays, custom window frames, or native hardware intents.

RoopM AgentOS pairs NVIDIA Nemotron constrained code synthesis with our custom Pure C++ Cross-Platform Engine, delivering capabilities impossible in standard HTML/CSS/JS wrappers:

1 · Zero-WebView Pure C++ W3C & Vector Runtime (2.45 MB .APK · 3.71 MB .EXE)

• Custom C/C++ Engine Stack: Replaces heavy browser runtimes with a unified C++ binary combining Lexbor (HTMLDOMBuilder · CSSParser · W3CSpecs), Yoga (CalculateLayout · FlexLine · AbsoluteLayout), QuickJS (JSDOMRuntime · WebEngine), and Blend2D + AsmJit SIMD-accelerated (SSE4.2 · SSSE3) 2D vector and stb_truetype font rendering (roopm_render · roopm_font · roopm_image).
• AI-Guided Engine-Safe Code Synthesis (CPP_ENGINE_SKILL.md): Standard unguided LLMs output heavy third-party CSS frameworks that break lightweight native parsers. Our Nebius Token Factory pipeline instructs Nemotron-3-Super-120B and Nemotron-3-Ultra-550B using strict system-prompt reference architectures to output 100% engine-compliant HTML / CSS / QuickJS and HTML5 Canvas code—producing ultra-fast calculators, media/video/music players, 2D canvas games, financial terminals, and automated business tools with zero layout breakage.

2 · Deep Android NDK (API 24 to 37) & Windows Win32 Native OS Controls

Through our custom AndroidBridge.h, OverlayManager.h, FramelessWindow.h, SpringPhysics.h, and GestureArena.h C++ subsystems, the AI agent can wire and control native OS features directly from simple HTML / CSS / JS:

• Android Floating Window Overlays (OverlayManager): Runs generated micro-apps, calculators, media players, and live AI trackers as draggable, always-on-top floating windows over any other mobile application.
• Android NDK System-UI & Edge-to-Edge Insets Control (API 24–37): Full programmatic control over status bar colors, navigation bar transparency, display cutouts, hardware DPI metrics (DisplayMetrics), and custom frameless window chrome (FramelessWindow) on Windows Win32.
• Native Push & Local Notifications: Triggers real OS-level notification banners and alerts from background events, live Tavily web triggers, or cloud form updates.
• Custom App Identity & Native Packaging Controls: Full control over custom package names (com.organization.app), auto-scaled <50KB launcher icons (mipmap-mdpi through xxxhdpi), custom splash screens, theme engines (ThemeEngine · CornerRadii · Shadow), PIN/biometric locks, direct WhatsApp/thermal-printer intents, and offline-first virtual file system (IVFS) storage queues.
• Native C++ Widget & Gesture Primitives: Hardware-accelerated SpringPhysics animations, multi-touch GestureArena / PointerRecognizers, DockingHost, SplitterView, DataTable, TreeView, ScrollView, and ModalDialog primitives.

3 · OpenShell-Inspired Zero-Knowledge Keystore Signing Vault (.jks · .pem · .der · .idsig)

• Directly inside the editor's smart chat dock, users can upload their own cryptographic signing assets (.jks, .pem, .der, .idsig) and enter keystore passwords to generate production-signed .APK (with V2/V4 .idsig signatures), Play-Store-ready .AAB, and .EXE binaries.
• Strict Secret Isolation: Keystore files and passwords bypass the AI model context completely—routing exclusively to our server build sandbox so private signing credentials are never exposed to any LLM.

02 · The 4-Stage Autonomous Agent Pipeline on Nebius Token Factory

Every user prompt, document design, or app generation task executes through a deterministic 4-Stage Pipeline visible live in the editor dock:

1. Stage 1 — Temporary Sandbox & Intent Triage (1. Temp Sandbox):
   • Snapshots the current multi-page scene-graph (Web vector layers and YAML / JSON schema) into an isolated sandbox.
   • nvidia/Nemotron-3_5-Lightning performs sub-second intent routing and dispatches runtime calls to the Tavily Search & Extract API whenever live 2026 external data, company financials, HSN/tax rates, or regulatory benchmarks are required.
2. Stage 2 — Parallel Multi-Model Synthesis (2A+2B. Parallel Edit):
   • Executes concurrent inference streams across Nebius Token Factory:
     • Stream 2A (nvidia/Nemotron-3-Super-120b-a12b · nvidia/Nemotron-3-Ultra-550b-a55b): Constructs structured Table (R×C) spreadsheets, evaluates tax/invoice formulas (SUM, GST, discounts, conditional formatting, and number-to-words), populates verified Tavily web data, binds {{Variable}} slots, and writes C++-compliant HTML / CSS / JS application logic.
     • Stream 2B (nvidia/Nemotron-3_5-Lightning): Simultaneously builds vector shapes, cubic Bézier paths, boolean pathfinder contours (Unite · Cut Front · Intersect · Exclude), curved path-following text, live alpha/luma track mattes, envelope warp meshes, multi-stop gradients, and (X, Y, W, H, Angle) coordinates.
   • Live Server-Driven Agent Cursor: Streams mutations directly onto the canvas with an animated visual cursor so users watch the agent build and align layers in real time.
3. Stage 3 — Autonomous Visual & Structural QA (3. QA Check):
   • Audits the sandboxed output using a mathematical bounding-box collision analyzer, W3C/C++ layout linter, and nvidia/Nemotron 3.5 Super VL vision inspection to detect text overlaps, vertical cell overflows across multilingual scripts (Gujarati, Hindi, English), contrast issues, or unsupported CSS rules.
4. Stage 4 — Closed-Loop Self-Healing (4. Auto-Fix):
   • Automatically resolves any detected geometry collisions, adjusts Y offsets and container heights, fixes untranslated nodes, and commits the verified scene-graph to the active workspace (completing 12-layer parallel builds and self-healing fixes in ~7.2 seconds).

03 · Canvas-to-Micro-Tool Automation & Two-Way Cloud Workflows

Using the same visual editor, users can convert any AI-generated or manually refined template into a Shareable Automated Micro-Tool (Edit ⇄ View Mode):

• Smart Forms, Voice/Text Autofill & Bulk CSV Generation: Automatically turns dynamic canvas layers into a clean form or CSV batch processor—allowing schools, businesses, and studios to generate hundreds of personalized certificates, GST invoices, ID cards, project reports, or passport photo grids in one click (exported as merged multi-page vector PDFs or individually named {{ID}}_{{Name}}.pdf ZIP archives).
• Print-Sheet Imposition & Exact File-Size Targeting: Automates step-and-repeat A4/4×6 grid layouts with cut marks, front/back duplex mirroring for double-sided ID cards, face-centering/background cleanup, and exact KB file-size compression sliders (e.g., 20KB–50KB regulatory limits).
• Two-Way Cloud Data Collection & Dynamic Verification QR: Shared tools and compiled .APK / .EXE apps remain connected to the creator's cloud workspace—allowing creators to collect form submissions, photos, and signatures from their end-users while embedding live verification/payment QR codes that dynamically update document states upon confirmation.

04 · Cloud Deployment & Evaluation Note

• Live Web & Multi-Agent Studio (https://roopm.com): Runs the complete vector canvas, 4-Stage Nebius Token Factory parallel agent pipeline, Web and YAML scene-graph controls, Edit / View micro-tool automation, and hybrid vector PDF/Image export live in the browser.
• Native C++ Compilation Pipeline: Because full C++ NDK/Win32 binary compilation requires dedicated multi-GB build memory, native .APK / .AAB / .EXE packaging runs via our dedicated build worker / pre-compiled binary asset-injection pipeline alongside in-browser simulation for instant cross-platform evaluation.
