So, I somehow ended up with this lovely girl

... I would not call her a "hybrid" at least in the sense most folks think about the term.

Carpets are crossed so often you'll never know exactly what you have unless you have data from the breeder.

it's not a hybrid (crossing two distinct species), it's an intergrade (crossing sub-species of the same species, in this case Morelia Spilota). As noted, m.s. intergrades are quite common. Hard to tell what they are sometimes, like in this case. However at 5-6 feet I would suspect there is some jungle in there, my expectation for a diamond/coastal intergrade would be a larger snake. but, who knows.
