 ### The Windows Background Daemon (`mcp-memory-server.exe`)
 The server executable is responsible exclusively for running the Axum HTTP and WebSockets daemon and managing the Knowledge Graph. It does not contain any proxy logic. If port 3000 is already in use by an existing server instance, it gracefully exits instead of attempting to run.
 
+*   **Non-Blocking Startup & Indexing:** Upon launch, the server uses a `tokio::spawn` task to rebuild the Tantivy index in the background. This ensures the Axum HTTP server binds immediately to port 3000, allowing instantaneous liveness checks via the `/ping` endpoint without waiting for the synchronous I/O operations of the index rebuild to complete.
+*   **Robust Background Detachment:** To ensure the server survives the death of the parent shell that spawns it (such as a deployment script), it uses Windows `WScript.Shell` (via `start_server.ps1`) to spawn the binary with a strictly hidden window style (`SW_HIDE`). This completely detaches it from the parent process tree, preventing `CTRL_CLOSE_EVENT` signals from killing the background daemon when the deploying terminal closes.

 ### The Client Proxy (`mcp-memory-stub.exe`)
 All Antigravity sessions (Windows and WSL) use the lightweight `mcp-memory-stub` as their proxy. The stub connects to the server via WebSockets and acts as the bridge for standard `stdio` JSON-RPC traffic.
 *   **Startup via Interop/Spawn:** Upon launch, the stub attempts to connect to the Windows host on port 3000. If the server is offline, the stub automatically executes a spawn command (e.g., executing `Start-Process` natively, or via WSL interop) to silently wake up the Windows Leader before commencing the proxy loop.

 ### B. Proactive Subagent Triggers
 The daemon will eventually gain the ability to autonomously spawn background subagents (like the `BugDiagnostician`) when specific events are detected in the webhook telemetry, rather than relying strictly on the human user to initiate the agent.
 
+## 11. Advanced Clipboard Capabilities
+The memory server bypasses typical cross-OS Linux/Windows clipboard restrictions by proxying operations from the WSL stub back to the Windows Axum host. 
+It supports reading and writing rich formats natively to the Windows Host OS using the clipboard-win and rboard crates:
+*   **Plain & Rich Text:** CF_UNICODETEXT and CF_HTML are supported for rich copying/pasting.
+*   **File Drops (CF_HDROP):** The server can parse file lists copied from Windows Explorer, and can inversely synthesize file drops into the clipboard from absolute paths.
+*   **Images (CF_BITMAP):** The server natively rasterizes clipboard bitmaps to JPEG on read, and can write raw RgbaImage buffers back to the clipboard on write.
+*   **Developer Tooling:** read_file_skeleton (AST), get_active_worktree_context (Git), get_recent_logs, toggle_clipboard_watch_mode.
