v0.1.5: The Architecture & OS Release

2022–2026 AI Innovations Suite: In-Place Auto-Updater, Native OS Daemons, In-Browser SQLite & Pyodide WASM, Live AI Metaprompter Wand, Non-Breaking Reading Zoom, 2D/3D Artifact Studios & Steve Jobs Mobile Ergonomics

Added

• In-Place Atomic Self-Updater (--update / update & GET /v1/update/check):
  • Automatically queries official GitHub Releases API, parses SemVer, downloads OS/Arch matching binary (darwin-arm64, darwin-amd64, linux-amd64, linux-arm64, windows-amd64.exe), verifies size, and replaces running executable in place via POSIX atomic rename and Windows .old rename.
  • Added live HTTP endpoint GET /v1/update/check so the web playground proactively checks and alerts users when newer releases are published.
• Native OS Background Service Daemons (service install | start | stop | status | uninstall):
  • Cross-platform native daemonization enabling 24/7 background operation across reboots with zero open terminals:
    • macOS: ~/Library/LaunchAgents/com.abcsteps.bob-gemini-free.plist with RunAtLoad and KeepAlive via launchctl.
    • Linux: ~/.config/systemd/user/bob-gemini-free.service via systemctl --user.
    • Windows: %APPDATA%\Microsoft\Windows\Start Menu\Programs\Startup\bob-gemini-free.bat.
  • Added live CLI subcommand suite: ./bob-gemini-free service [install|start|stop|status|uninstall].
• In-Browser SQLite WASM Database Studio (🗄️ SQL WASM):
  • Integrated official SQLite WebAssembly (sql.js) engine running client-side with zero cloud costs.
  • Automatic [ Run SQL ⚡ ] action card chips on all ```sql code blocks.
  • Interactive table viewer rendering formatted data with column headers, formatted numbers, row counts, and microsecond execution timer (⚡ 0.8ms).
  • Interactive SQL query editor allowing users to run live SELECT, INSERT, UPDATE, and CREATE TABLE queries directly in the browser sandbox.
• Institutional-Grade In-Browser Pyodide WASM Python Execution Engine:
  • Live client-side CPython 3.11 execution in an isolated in-memory WebAssembly sandbox with zero server-side execution risk, zero Python installation required, and zero cloud billing.
  • Dedicated 🐍 Python WASM Live Sandbox [ Run WASM ⚡ ] interactive Artifact Card Chips automatically attached to all Python code blocks.
  • Dynamic Code Sanitization Engine (sanitizePythonCode): Automatically strips conversational text, markdown headers, and trailing fences before AST parsing to prevent SyntaxError crashes.
  • Interactive input() Prompt Hook: Intercepts builtins.input via browser prompt with clean cancellation handling (KeyboardInterrupt) so interactive scripts and financial simulations run smoothly.
  • Dynamic Scientific Package Auto-Loader: Inspects code for numpy, pandas, matplotlib, scipy, sympy and dynamically streams WebAssembly package wheels on demand.
  • Cyberpunk Dark Terminal & Performance Timer: Real-time sys.stdout streaming, red error highlights, and sub-10ms execution reporting (✔ Finished in 7.0ms).
• Native Interactive Artifacts Canvas Studio (Claude-Class Live Sandbox):
  • Automatic code block detection & registration into an in-memory artifactsRegistry.
  • Rich Artifact Card Chips in chat with title extraction, type badge, and 1-click Launch ⚡ button.
  • Dedicated Interactive Artifact Studio Canvas Modal with sandboxed iframe execution (allow-scripts allow-modals allow-forms allow-same-origin) supporting live HTML5, CSS3, JavaScript, Canvas 2D/WebGL simulations & games, SVG vector rendering, and Mermaid architecture diagrams.
  • Dual Tab switcher ([ ▶ Preview | ⟨/⟩ Code ]), sandbox reload (⟳), quick copy (📋), standalone file export (💾), and instant fullscreen pop-out (⛶) in dedicated browser windows.
• Live AI Prompt Metaprompting Wand Engine (🪄):
  • Upgraded from static heuristic regex to a real-time AI prompt optimization engine: makes a background call to local BOB gateway (/v1/chat/completions) using gemini-3.7-flash to transform rough thoughts into structured, precision master prompts in ~200ms.
  • Seamless, zero-latency offline fallback to structured templates (Game/App, Math/Physics, Code/Architecture, General) when offline or unreachable.
  • Keyboard shortcut (⌘ + Shift + P / Ctrl + Shift + P) and sparkling button glow animation.
• Subtle, Non-Breaking Reading Zoom Controller (🔍 100%):
  • Dynamically scales reading typography (calc(0.92rem * var(--reading-zoom))) on assistant responses, markdown text, thought blocks, and code blocks while keeping header, sidebars, starter cards, and input layout 100% fixed, stable, and unbroken.
  • Integrated 1-click sub-bar cycle pill (100% $\rightarrow$ 115% $\rightarrow$ 130% $\rightarrow$ 85% $\rightarrow$ 100%), Command Palette (⌘K) quick commands, and keyboard shortcuts (⌘ + / Ctrl +, ⌘ - / Ctrl -, ⌘ 0 / Ctrl 0) with localStorage persistence.
• Symmetrical Radha-Krishna $2 \times 2$ 4-Flagship Masterpiece Matrix:
  • Replaced cramped 8-card grid with a spacious, soothing, balanced $2 \times 2$ matrix showcasing the platform's 4 defining superpowers:
    1. 🎮 Artifact Canvas Studio: 2D Cyberpunk Snake Game (HTML5 Canvas 60fps arcade).
    2. 🐍 Python WASM Sandbox: Quantitative Finance & Risk (Black-Scholes & Monte Carlo) (NumPy option pricing, 5 Greeks, and 10,000-path VaR).
    3. 🪐 Three.js WebGL Studio: 3D Solar System & Orbit Lab (Photorealistic N-body gravity simulator with 360° OrbitControls).
    4. 🎓 First Principles & Mental Models: Explain to a 5th Grader (Intuitive analogies with Mermaid visual diagrams).
• In-Place User Message Editing & Conversation Branching Engine:
  • True in-place DOM transformation: clicking ✏️ on any past user bubble instantly transforms the card into an inline editor with auto-growing textarea and [ Save & Submit ] / [ Cancel ] buttons.
  • Full conversation rewind and re-branching (chatHistory.slice(0, idx)), restoring any attached multimodal images or document context.
  • Keyboard ergonomics: Ctrl+Enter / ⌘+Enter to submit, Escape to cancel.
• Natural HD Speech Engine & Floating Audio Controller Bar (NotebookLM-Class Voice Studio):
  • Intelligent Neural Voice Scoring Engine (getBestNaturalVoice): Automatically filters out legacy robotic synths and prioritizes ✨ Studio HD Natural Voices (Google US English, Google हिन्दी, Samantha Enhanced, Ava Premium, Rishi, Lekha).
  • Dharmic Glassmorphic Floating Audio Player Bar: Bottom-docked player equipped with Play / Pause toggle (⏸️ / ▶️), Cycle Speed chip (0.8x, 1.0x, 1.25x, 1.5x), Live 4-bar pulsating sound equalizer (ılılı), Sentence Progress Counter (Sentence X of Y), and Stop (⏹️).
  • Sentence-by-Sentence Fluid Cadence: Chunking parser that prevents browser 15-second speech synthesis timeouts and delivers natural human conversational pacing.
• Steve Jobs Level Mobile Ergonomics & 2-Tier Input Dock:
  • position: fixed !important; off-canvas drawer architecture for Config and Code panels, eliminating flex margin shifts on mobile viewports.
  • 2-tier mobile input layout: 100% wide auto-resizing textarea on top; tools dock (📎, अ, 🎙️, 🪄) and golden SEND ➤ CTA on bottom.
  • Guaranteed Apple HIG 44pt touch target compliance, dynamic viewport height (100dvh), and notch/home-indicator safe area inset support (env(safe-area-inset-*)).

Fixed

• Message Editing Pointer Jump Bug: Resolved DOM click binding and positional tracking (data-msg-idx) so message editing happens strictly in-place without scrolling to the bottom input box.
• Textarea Horizontal Scrollbar Elimination: Added overflow-x: hidden !important;, scrollbar-width: none !important;, and overflow-x enforcement in autoResize(el) to permanently eliminate unwanted horizontal scrollbar rendering across WebKit and Blink browsers.
• Pyodide Sync Cancellation: Added KeyboardInterrupt exception handling when user cancels input() dialogs.
