No it does not.
The cryptographic seal is calculated over the content of the commit,
which includes the hashes of all referenced objects, but doesn't include
the objects themselves.
The content of the commit is not violated.
Do not forget though:
- origin links are a rare occurrence.
- When they occur, they usually were made to point into other (deemed)
important public branches.
- Due to the fact that the branches they are pointing into are important
and public, in most cases the origin links *will* point to objects you
actually already have (even if you fetched from someone else).
- The only time you're going to have dangling origin links is when
they were pointing at someone's private branches, in which case it was
not very prudent of the committer to actually record the link in the
first place. But nothing breaks if you don't have his private branch
locally.
