Mohamed Boudra 1977d330ed Reduce workspace, agent, and chat sync traffic (#2028)
* feat(sync): keep live data scoped and current

Only viewed chats receive live timeline rows, while directory state now uses one subscribed bootstrap followed by ordered deltas. Legacy clients and daemons retain their existing behavior through centralized compatibility gates.

* fix(sync): preserve selective delivery boundaries

Keep selective timeline capability app-owned, union viewed sets across shared sockets, and reconcile directory side effects from accepted state. Visibility and archive suppression now follow their existing authoritative boundaries.

* test(app): align browser fixtures with runtime contracts

* fix(sync): preserve mixed-client delivery guarantees

* fix(sync): finish paged history before advancing

* fix(sync): replay live deltas after refresh failures

* test(server): model socket capability lookup

* test(app): use platform shortcut for split-pane coverage

* fix(app): keep hidden timelines dormant

* test(app): normalize split-pane shortcut setup

* fix(app): preserve sync state across retries

* fix(app): preserve background sync state across races

* fix directory bootstrap reconciliation edge cases

* fix selective timeline compatibility races

* fix superseded directory sync races

* fix(sync): centralize directory replica ordering

Own agent and workspace refresh transactions in HostRuntime so reconnect epochs, buffered updates, and lifecycle invalidation share one ordering boundary. Route timeline metadata and mixed-capability stream delivery through their authoritative runtime sources.

* fix(app): keep timeline requests runtime-scoped

* fix(app): close directory bootstrap races

Voice Assistant

A voice-controlled terminal assistant that runs as a single local service.

Quick Start

# Install dependencies
npm install

# Copy environment variables
cp .env.example .env
# Edit .env and add your API keys (OpenAI, Deepgram)

# Run development servers
npm run dev

# Open browser to http://localhost:5173

Architecture

  • Express Server (port 3000) - Serves API and built UI in production
  • Vite Dev Server (port 5173) - Hot-reload React UI in development
  • WebSocket (/ws) - Real-time bidirectional communication
  • Agent - STT → LLM → TTS pipeline with terminal control
  • Daemon - tmux-based terminal management (in-process)

Development

# Run both servers (recommended)
npm run dev

# Or run separately:
npm run dev:server  # Express on port 3000
npm run dev:ui      # Vite on port 5173

# Type checking
npm run typecheck

# Build for production
npm run build

# Start production server
npm start

Project Status

Completed (Phases 1-2):

  • Package setup and configuration
  • Express server with WebSocket
  • React UI with Vite
  • WebSocket client with ping/pong testing

In Progress (Phase 3):

  • Terminal control (tmux integration)

📋 Planned (Phases 4-9):

  • LLM integration (OpenAI GPT-4)
  • Agent orchestrator
  • Speech-to-Text (Deepgram)
  • Text-to-Speech (OpenAI)
  • Audio streaming
  • UI polish

See IMPLEMENTATION_PLAN.md for complete details.

Environment Variables

OPENAI_API_KEY=your-openai-key-here      # GPT-4 and TTS
DEEPGRAM_API_KEY=your-deepgram-key-here  # Streaming STT
STT_MODEL=whisper-1        # Optional: override to gpt-4o-transcribe, etc.
STT_CONFIDENCE_THRESHOLD=-3.0  # Optional: reject low-confidence clips
STT_DEBUG_AUDIO_DIR=.stt-debug # Optional: persist raw dictation audio for debugging
PASEO_HOME=~/.paseo        # Runtime state directory (agents/, etc.)
PASEO_LISTEN=127.0.0.1:6767  # Listen address (host:port or /path/to/socket)

PASEO_HOME defaults to ~/.paseo and isolates runtime artifacts like agents/. PASEO_LISTEN controls the daemon listen address. For blue/green testing you can run a parallel server without touching production state:

PASEO_HOME=~/.paseo-blue PASEO_LISTEN=127.0.0.1:7777 npm run dev

Tech Stack

  • Server: Express, TypeScript, ws (WebSocket)
  • Client: React 18, Vite, TypeScript
  • Terminal: tmux (via child_process)
  • AI: OpenAI (LLM + TTS), Deepgram (STT)

Testing

Currently manual testing via:

  1. Start servers: npm run dev
  2. Open http://localhost:5173
  3. Test WebSocket connection (green status indicator)
  4. Click "Send Ping" button to test communication

More testing guidance as features are implemented.
