There is however an important component in it that I feel the basic
definition you presented is missing, more on that below.

Than apparently this is the core of our disagreement on this subject.
Your view is that ambient authority is only that authority that originates
from ambient permissions.
My interpretation of the term ambient authority would next to authority
originating from ambient permissions also include authority originating
from static (implicitly shared) designating permissions.
I thus feel that a definition of ambient authority should not be the same
as a definition of ambient permission.
