The habituation your rabbit has is unique. One of the main factors is environmental control. Between predators, unknown chemicals in the plants, insects, and weather, there are a lot of things that can go wrong to make a rabbit ill or in danger. Because of this, it’s more preferable to have a rabbit indoors and have them outdoors under supervision. It only takes a wandering hawk to identify a rabbit in a garden to put the rabbit in danger, or a stray cat or dog that is very persistent. An especially bad mosquito season or infestation at a nearby home. Keeping the rabbit secure and safe is essential. A secure, high fence that runs deep into the ground to prevent digging predators, and covered shelters under the circumstance an avian predator sees your rabbit and a retreat is needed.
If you’re in an environment where you know everything is controlled, such as your own farm, property, garden, etc., it’s better since there are less unknowns, but they still exist. It’s good to hear you take the rabbit in for major weather. I do suggest adding hot weather to that list as well. Consider rabbits as humans always wearing a coat.
In short, the recommendation is not to have your rabbit unsupervised outdoors 24/7 because there are many more things that can go “wrong” outdoors than indoors. Keep that in mind going forward and if you feel her run is not adequate for all possible scenarios, take action to make it so!
