Mohamed Boudra 48a1497fc0 Load the Changes diff quickly while the daemon reconciles worktrees (#9243)
* fix(server): keep cold diffs out from behind background git fan-out

Add a background lane to the git process scheduler and run reconciliation
checkout reads, observation-driven workspace refreshes and background fetches
in it. Bound reconciliation checkout reads to four at a time. Stop the Linux
file observer's startup scan from reporting existing files as creates, which
made every cold diff compute and discard its first revision.

* fix(server): pick the git job when its start token fires

Background jobs that already reserved a start-rate token no longer start
ahead of normal work submitted after them.

* fix(server): re-read the working tree once its watcher covers it

The Linux observer no longer reports pre-existing files at startup, so an
edit made between a workspace's first snapshot and its watcher subscribing
reached no consumer. WorkspaceGit now runs one background working-tree read
once observation setup completes with a live watcher.

Demand refreshes keep the caller's Git lane instead of forcing normal, so
user actions running at high priority are not demoted.

Scope the populated-tree observer test to Linux (FSEvents replays recent
writes) and update the observer benchmark test, which expected the removed
startup batch.

* fix(server): re-read checkout metadata once observation covers it

A branch switch made before the Git metadata watcher subscribed left the
cached branch stale. The post-coverage read now refreshes structure as well
as the working tree, matching the refresh the Linux startup events used to
trigger.

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.
