# Refactor: Implement Robust Startup Sequence and Health Checks in Memory Core

The Memory Core MCP server entry point (`mcp-stdio.mjs`) has been refactored to implement a more robust and informative startup sequence, leveraging the recent enhancements to the `HealthService`.

### Key Changes:

1.  **Proactive Startup Health Check**: The server now performs a comprehensive health check immediately upon starting.
2.  **Detailed Status Logging**: Based on the health status (`healthy`, `degraded`, `unhealthy`), the server logs detailed, user-friendly messages, including actionable tips for resolving issues (e.g., how to start the ChromaDB if it's not running).
3.  **Automatic Session Summarization**: If the health check passes and the `GEMINI_API_KEY` is configured, the server automatically triggers a background task to summarize any previously unsummarized sessions.
4.  **Tool Execution Gatekeeper**: The main tool handler now calls `HealthService.ensureHealthy()` before executing most tools. This prevents operations from failing with cryptic errors if a dependency is down.
5.  **Precise Health Check Exemptions**: The logic for skipping the health check has been refined from a broad string match (`.includes('database')`) to a specific allow-list (`['healthcheck', 'start_database', 'stop_database']`), making it safer and more explicit.

These changes improve the server's resilience, provide better feedback to the user, and automate routine maintenance tasks.
