NCP 2.3.0 - photon-core 2.9.4 Integration

Major Features

🎯 Photon-Core 2.9.4 Integration

PhotonWatcher - Battle-tested file monitoring with symlink resolution, debouncing, and automatic hot-reload

• Replace chokidar with production-ready watcher
• Symlink resolution for macOS compatibility
• Temp file filtering and debouncing built-in

DaemonBroker - Cross-process event routing via Unix sockets

• Photons emit events with await this.emit()
• Subscribe with @notify-on annotations
• Graceful fallback to local-only when daemon not running

InstanceStore - State persistence across execution sessions

• Photons implement getState()/setState() for automatic persistence
• State saved to ~/.photon/state/{photonName}/
• State restored on load automatically

StatefulExecution - Execution tracking with runId and StateLog

• Every code execution gets unique runId
• JSONL logs stored at ~/.photon/runs/{runId}.jsonl
• Foundation for Code-to-Photon workflow

🔄 Code-to-Photon Workflow

Three new MCP tools enable permanent automation:

• code:run - Execute TypeScript with full MCP access
• code:list-runs - List recent executions
• code:get-run - Inspect execution details
• code:save-as-photon - Convert code → .photon.ts file

Workflow: Write code → Execute → Success! → Save as Photon → Use forever

📱 MCP Apps Protocol Support

Groundwork for visual components in tool results. Detects client capabilities for future UI rendering.

Security

• Applied 24 npm security fixes
• Remaining 19 vulnerabilities are unfixable at npm level (mostly in devDependencies)
• Upgraded mcp-server-kubernetes to 3.3.0 (fixes deprecated request package chain)

Documentation

Four comprehensive guides created:

• Code-to-Photon - Workflow automation
• Stateful Execution - State persistence
• Daemon Integration - Event routing
• NCP 2.3.0 Features - Feature overview
