 *   `GET /sse`: The Server-Sent Events (SSE) endpoint. Antigravity clients connect here to keep a one-way pipe open for receiving pushed responses.
 *   `POST /messages`: The JSON-RPC endpoint. Clients use this to send tool calls and resource reads up to the server when connected via SSE.

+### Dashboard REST API
+The server hosts a rich Single Page Application (SPA) natively on the root route, backed by a suite of REST endpoints:
+*   `GET /`: The Brain Monitor live HTML dashboard SPA.
+*   `GET /api/graph`: Returns the full node/edge topology for the interactive physics-simulated canvas.
+*   `GET /api/tasks` & `POST /api/tasks/{id}/complete`: Drives the actionable Kanban board.
+*   `GET /api/sticky` & `GET /api/search`: Powers the sticky notes tab and global fuzzy search UI.
 *   `GET /api/stats`: Returns a JSON snapshot of current entity, relation, task, and tech debt counts.
-*   `GET /gate/verify`: A lightweight, deterministic endpoint used by external scripts to verify if an action (like a `git push`) is authorized based on the current state.

+### Git & IDE Integration Endpoints
+*   `POST /nvim/telemetry`: A one-way webhook that Neovim instances hit on `FocusGained` or `BufEnter` to globally broadcast the user's active file to the UI and Agent.
+*   `GET /gate/verify`: A lightweight, deterministic endpoint used by external scripts (like a `git push` wrapper) to verify if an action is authorized based on the current state.
