+**What it shows:**

+| **Throughput sparkline** | Per-second request rate for the last 60 seconds — see traffic patterns at a glance |
+| **Top paths** | Most-requested URLs with hit count and average response time — find your hot paths |
+| **Active rooms** | WebSocket room workers with member count — monitor real-time features |
+| **Live request log** | Scrolling feed of every request: timestamp, status code (color-coded), method, URI, response time in ms |
+
+**Endpoints:**

+| `/Q/health` | JSON | Load balancers, uptime monitors (lightweight) |
+| `/Q/stats` | JSON | Monitoring systems — full stats payload |

+## 💡 The mental model
+
+Three files for a complete real-time app:
+
+```
+handlers/game/join.php       ← adds player to static $players
+handlers/game/move.php       ← updates static $positions, broadcasts
+handlers/game/leave.php      ← removes player, notifies room
+```
+
+No Redis. No message queue. No pub/sub infrastructure. No WebSocket library.
+No event loop to learn. Just PHP files in a folder.
+
+The developer's decision tree:
+
+```
+Does this data matter after disconnect?
+  No  → static variable              (cursors, typing, game positions)
+  Yes → database call                (messages, scores, transactions)
+
+Does anyone else need to see it?
+  No  → just update your static var
+  Yes → Q_Socket::broadcast()
+```
+
+Ephemeral state lives in RAM — static variables in the per-connection process.
+It's fast (no I/O), isolated (per-user process boundary), and self-cleaning
+(process dies on disconnect, OS reclaims everything). When you need durability,
+call your preloaded classes to write to a database. When you need to notify
+others, call `Q_Socket::broadcast()`.
+
+The same `handlers/` directory serves HTTP requests, WebSocket messages, and
+routed clean URLs. The same `classes/` directory is preloaded and shared across
+all of them. One server, one codebase, one mental model.
+
+```
+Static files:    GET /style.css            → web/style.css
+PHP scripts:     GET /page.php             → web/page.php
+Routed:          GET /api/users            → handlers/api/users/get.php
+WebSocket:       {"event":"chat/message"}  → handlers/chat/message.php
+Legacy:          GET /wp-admin/post.php    → php-cgi (full compatibility)
+```
+
+When you outgrow it — when you need the full dispatch pipeline, Streams for
+real-time data synchronization, or the component-level cache invalidation
+with Merkle trees — the same handlers run on the
+[Qbix Platform](https://github.com/Qbix/Platform) without changes. The upgrade
+path is adding capability, not rewriting architecture.
