+# 2026-01-07-move-status-to-footer
+
+**Status:** Done
+**Created:** 2026-01-07
+**Tags:** ui, layout, enhancement
+
+## 1. Context & User Story
+* **As a:** User of the Web Interface
+* **I want to:** see the system status and uptime information in the footer of every page
+* **So that:** the main content area is less cluttered and status information is globally available.
+
+## 2. Technical Requirements
+### Data Model Changes
+- [ ] N/A
+
+### API / Interface
+- [x] **Home Page:** Remove the "Status" card from the main content.
+- [x] **Layout:** Update `BaseLayout` (or `layout.ts`) to accept or calculate uptime/status information and render it in the `<footer>`.
+
+## 3. Constraints & Validations (CRITICAL)
+- **Visuals:** The footer should remain clean and not be overcrowded.
+- **Functionality:** The existing client-side uptime counter (via `#uptime-display` in `script.js`) must continue to work. Ensure the ID or data attributes it relies on are preserved in the new location.
+
+## 4. Acceptance Criteria
+1. [x] The "Status" card is removed from the Home page content.
+2. [x] The Footer displays "System Operational" and the running Uptime counter.
+3. [x] navigation to other pages (if any) still shows the status in the footer.
+
+## 5. Implementation Plan
+- [x] Edit `src/web/routes/home.ts` to remove the Status card.
+- [x] Edit `src/web/views/layout.ts` to add the Status HTML structure to the footer.
+- [x] Verify `script.js` selector targets the new element correctly.
+
+## Implementation Notes
+- Moved Status/Uptime logic from `home.ts` to `layout.ts` (footer).
+- Calculated server-side uptime for initial rendering to prevent flash.
+- Preserved `id="uptime-display"` and `data-start-timestamp` for `script.js` compatibility.
+- Updated tests to verify uptime presence in global layout.

+# 2026-01-07-web-interface-feature-expansion
+
+**Status:** Draft
+**Created:** 2026-01-07
+**Tags:** product-design, feature-request, ui
+
+## 1. Context & User Story
+* **As a:** Bot Administrator
+* **I want to:** have more useful features on the web dashboard
+* **So that:** getting insights into the bot's performance and managing it becomes easier than using text commands.
+
+## 2. Technical Requirements
+### Proposed Features
+1.  **Live Console / Activity Feed:**
+    *   Stream abbreviated logs or important events (e.g., "User X joined", "Command Y executed").
+2.  **Metrics Dashboard:**
+    *   Visual charts for command usage (Top 5 commands).
+    *   Memory usage and CPU load over time.
+    *   API Latency gauge.
+3.  **Command Palette / Control Panel:**
+    *   Buttons to clear cache, reload configuration, or restart specific services.
+4.  **Guild/User Browser:**
+    *   Read-only list of top guilds or users by activity/economy balance.
+
+### Data Model Changes
+- [ ] May require exposing existing Service data to the Web module.
+
+### API / Interface
+- [ ] `GET /api/stats` or `WS` subscription for metrics.
+- [ ] `GET /api/logs` (tail).
+
+## 3. Constraints & Validations (CRITICAL)
+- **Security:** Modifying bot state (Control Panel) requires strict authentication/authorization (Future Ticket). For now, read-only/safe actions only.
+- **Privacy:** Do not expose sensitive user PII in the web logs or dashboard without encryption/masking.
+
+## 4. Acceptance Criteria
+1. [ ] A list of prioritized features is approved.
+2. [ ] UI Mockups (code or image) for the "Dashboard" view.
+3. [ ] Data sources for these features are identified in the codebase.
+
+## 5. Implementation Plan
+- [x] **Phase 1:** Brainstorm & Mockup (This Ticket).
+- [ ] **Phase 2:** Create individual implementation tickets for selected features (e.g., "Implement Metrics Graph").
+
+## Implementation Notes
+- Created `/dashboard` route with a code-based mockup.
+- Implemented responsive CSS Grid layout for the dashboard.
+- Integrated real `AuroraClient` data for Server Count, User Count, and Command Count.
+- Added placeholder UI for "Live Activity" and "Metrics".
+- Next steps: Connect WebSocket "HEARTBEAT" to the dashboard metrics and implement real logger streaming.

+# 2026-01-07-websocket-realtime-data
+
+**Status:** Done
+**Created:** 2026-01-07
+**Tags:** feature, websocket, realtime, research
+
+## 1. Context & User Story
+* **As a:** Developer
+* **I want to:** implement a WebSocket connection between the frontend and the Aurora server
+* **So that:** I can stream real-time data (profiling, logs, events) to the dashboard without manual page refreshes.
+
+## 2. Technical Requirements
+### Data Model Changes
+- [ ] N/A
+
+### API / Interface
+- [x] **Endpoint:** `/ws` (Upgrade Upgrade: websocket).
+- [x] **Protocol:** Define a simple JSON message format (e.g., `{ type: "UPDATE", data: { ... } }`).
+
+## 3. Constraints & Validations (CRITICAL)
+- **Bun Support:** Use Bun's native `Bun.serve({ websocket: { ... } })` capabilities if possible.
+- **Security:** Ensure that the WebSocket endpoint is not publicly abusable (consider simple token or origin check if necessary, though internal usage is primary context for now).
+- **Performance:** Do not flood the client. Throttle updates if necessary.
+
+## 4. Acceptance Criteria
+1. [x] Server accepts WebSocket connections on `/ws`.
+2. [x] Client (`script.js`) successfully connects to the WebSocket.
+3. [x] Server sends a "Hello" or "Ping" packet.
+4. [x] Client receives and logs the packet.
+5. [x] (Stretch) Stream basic uptime or heartbeat every 5 seconds.
+
+## 5. Implementation Plan
+- [x] Modify `src/web/server.ts` to handle `websocket` upgrade in `Bun.serve`.
+- [x] Create a message handler object/function to manage connected clients.
+- [x] Update `src/web/public/script.js` to initialize `WebSocket`.
+- [x] Test connection stability.
+
+## Implementation Notes
+- Enabled `websocket` in `Bun.serve` within `src/web/server.ts`.
+- Implemented a heartbeat mechanism broadcasting `HEARTBEAT` events every 5s.
+- Updated `script.js` to auto-connect, handle reconnects, and update a visual "online" indicator.
+- Added `src/web/websocket.test.ts` to verify protocol upgrades and messaging.
