When Does Entity Attributes Get Filled

Entities aren’t filled via the constructor when returned as part of a database query result (this includes Models), but rather have each attribute set one at a time. See e.g.:

You could probably create your own magic getter for posts that would load it on-the-fly, but I’m not entirely sure of its interaction with toArray(). I use this kind of “lazy load” for my Relations Entity trait and it works very well - no extra loading of related items if you don’t need them.
