Hi,
I am trying to understand the solved plugin to get a better idea of creating plugins. I had a few questions about code snippets from the solved plugin.
[https://github.com/discourse/discourse-solved/blob/master/assets/javascripts/discourse/solved-route-map.js.es6](https://github.com/discourse/discourse-solved/blob/master/assets/javascripts/discourse/solved-route-map.js.es6)
In the tutorial for developing plugins, there was a path field, why isn’t there one in the solved route-map?
In the plugin.rb file, I couldn’t find the solved plugin version of
```ruby
add_admin_route 'purple_tentacle.title', 'purple-tentacle'
```
How does the solved plugin, achieve the solved interface in the user activity? How are the notifications linked to this interface?
Thank you

As per the above code a common filter path is already available in Discourse core. So we don’t need to add the solved activity filter `u/:username/activity/solved` again in plugin code.
