+# Browser Contract — The Nexus
+
+The minimal set of guarantees a working Nexus browser surface must satisfy.
+This is the target the smoke suite validates against.
+
+## 1. Static Assets
+
+The following files MUST exist at the repo root and be serveable:
+
+| File              | Purpose                          |
+|-------------------|----------------------------------|
+| `index.html`      | Entry point HTML shell           |
+| `app.js`          | Main Three.js application        |
+| `style.css`       | Visual styling                   |
+| `portals.json`    | Portal registry data             |
+| `vision.json`     | Vision points data               |
+| `manifest.json`   | PWA manifest                     |
+| `gofai_worker.js` | GOFAI web worker                 |
+| `server.py`       | WebSocket bridge                 |
+
+## 2. DOM Contract
+
+The following elements MUST exist after the page loads:
+
+| ID                    | Type     | Purpose                            |
+|-----------------------|----------|------------------------------------|
+| `nexus-canvas`        | canvas   | Three.js render target             |
+| `loading-screen`      | div      | Initial loading overlay            |
+| `hud`                 | div      | Main HUD container                 |
+| `chat-panel`          | div      | Chat interface panel               |
+| `chat-input`          | input    | Chat text input                    |
+| `chat-messages`       | div      | Chat message history               |
+| `chat-send`           | button   | Send message button                |
+| `chat-toggle`         | button   | Collapse/expand chat               |
+| `debug-overlay`       | div      | Debug info overlay                 |
+| `nav-mode-label`      | span     | Current navigation mode display    |
+| `ws-status-dot`       | span     | Hermes WS connection indicator     |
+| `hud-location-text`   | span     | Current location label             |
+| `portal-hint`         | div      | Portal proximity hint              |
+| `spatial-search`      | div      | Spatial memory search overlay      |
+| `enter-prompt`        | div      | Click-to-enter overlay (transient) |
+
+## 3. Three.js Contract
+
+After initialization completes:
+
+- `window` has a THREE renderer created from `#nexus-canvas`
+- The canvas has a WebGL rendering context
+- `scene` is a `THREE.Scene` with fog
+- `camera` is a `THREE.PerspectiveCamera`
+- `portals` array is populated from `portals.json`
+- At least one portal mesh exists in the scene
+- The render loop is running (`requestAnimationFrame` active)
+
+## 4. Loading Contract
+
+1. Page loads → loading screen visible
+2. Progress bar fills to 100%
+3. Loading screen fades out
+4. Enter prompt appears
+5. User clicks → enter prompt fades → HUD appears
+
+## 5. Provenance Contract
+
+A validation run MUST prove:
+
+- The served files match a known hash manifest from `Timmy_Foundation/the-nexus` main
+- No file is served from `/Users/apayne/the-matrix` or other stale source
+- The hash manifest is generated from a clean git checkout
+- Screenshot evidence is captured and timestamped
+
+## 6. Data Contract
+
+- `portals.json` MUST parse as valid JSON array
+- Each portal MUST have: `id`, `name`, `status`, `destination`
+- `vision.json` MUST parse as valid JSON
+- `manifest.json` MUST have `name`, `start_url`, `theme_color`
+
+## 7. WebSocket Contract
+
+- `server.py` starts without error on port 8765
+- A browser client can connect to `ws://localhost:8765`
+- The connection status indicator reflects connected state
