Hey! Excellent noticing there!
Yes, you are entirely correct, my issues are/were ownership related. And
my wording was largely due to me misunderstanding the meaning of the
word "permission", as in german, that identifies the larger concept
which can be dealt with by many different implementations (more or
less), whereas you identified the implementational detail called
"permission bits", which my vague, imprecise description accidentally
did not exclude.
Thank you anyhow for pointing this out, as it also clarifies my
thinking, and possibly the things, i am going to try to fix the issue.
As i said: Excellent noticing.
Thank you, DdB
