# Description
This PR moves the categorisation of Bookings with Incidents from the flagging specific model to Booking Summary, effectively keeping this at Booking ID level.
This also handles the direct dependency with the flagging categorisation model.
I also improved the documentation and test coverage on the Booking Summary as it's becoming more and more central to many areas.
