You forgot the asterisks based on RC teaching.
* Only when the pope is speaking ex cathedra (but which statements belong to that class is subject to debate)
*Encyclicals, if perhaps not Bulls, also require assent, and are protected from salvific error.
*Basically all formal papal public teaching on faith and morals requires assent, and is protected from salvific error
*Social teaching is also requires assent, and is protected from salvific error.
* Protection from error refers only to words, not deeds (the latter being what Biblically reveals what is really believed).
There may be more.
Sad laugh...
