 `PHPForge\Inertia\Debug\InertiaPanel`; the host never reimplements collection or presentation. What differs between
 frameworks is only how the dispatcher reaches the `PHPForge\Inertia\Protocol` service.
 
-### Yii3, one flag and no application code
+### Yii3, from `yii3/debug` 0.1.0
 
-`yii3/debug` registers the collector and panel behind a flag and attaches the collector as a listener; the container
-autowires `Psr\EventDispatcher\EventDispatcherInterface` into `Protocol`, so the application adds nothing else.
+`yii3/debug` registers the collector and the panel in its packaged parameters as soon as this package is installed,
+routes `ProtocolResultCreated` to that collector from its packaged `events-web` group, and builds the collector with
+the host `CapturePolicy` redaction callbacks. The container autowires `Psr\EventDispatcher\EventDispatcherInterface`
+into `Protocol`, so the application adds nothing. Disable both packaged entries with `enabled => false` when the
+capture is unwanted.
 
-```php
-return [
-    'yii3/debug' => [
-        'extensions' => [
-            'inertia' => true,
-        ],
-    ],
-];
-```
+### Yii2, from `yii2-extensions/debug` 0.2.0
 
-Enabling the flag without `php-forge/inertia` installed fails with an explicit container error. The collector receives
-the host `CapturePolicy` redaction callbacks automatically.
+Yii2 has no framework-native PSR-14 dispatcher, and its DI container does not autowire optional constructor arguments.
+`Protocol` emits exactly one event type, so `InertiaCollector` is its own single-listener dispatcher.
+`yii2-extensions/debug` registers the collector and the panel once this package is installed, builds the collector
+with the module capture policy, and hands it to the `inertia` component through
+`yii\inertia\Manager::$eventDispatcher` before the request runs. A component that configures `eventDispatcher` or
+`protocol` itself keeps what it configures; disable the packaged entries with `enabled => false` when the capture is
+unwanted.
 
-### Yii2, one registration
+If the application already owns a real PSR-14 dispatcher, register the collector as a listener on it and inject that
+dispatcher instead; never replace a populated dispatcher with an empty one. Inject the dispatcher into the **actual**
+`Protocol` service, not into a duplicate diagnostic-only one. Omitting it is safe: the protocol behaves normally and
+the panel simply stays empty.

+Earlier releases package no Inertia entry: they wrap the portable objects in their generic adapters and group them
+under Extensions, and the `inertia` ID is free for the application to register. Without that registration the panel
