Not technically true. If I make a commit with SHA x, push it, and it
gets submitted, then it is true that the final SHA in master will be y
!= x. However, the next time I pull then I will get SHA y as well.
They x and y technically reference different commits, since y contains
additional information about who reviewed it, when it was submitted
from Gerrit, etc.


But aren't we talking about users, rather than devs?  Users will either
build from a clone from the main repo, or use an automated build, thus their
reference point will be the Gerrit | master SHA whichever is the most
appropriate name for it.

In any case I don't think this fulfils the initial question.  Previously we
could say to users that an issue was fixed in svn r nnnn and they would
"know" that any rev later than that was good.  I don't understand how they
can "know" that with a SHA of the latest master commit | merge.

SHAs aren't ordered like SVN revisions are (so given two arbitrary
SHAs and nothing else I can't determine which came first) but they do
still have an ordering in the repository.

Regardless, we can say: fixed in commit SHA. They can pull, and if
"git show SHA" shows the revision then they've got it. Otherwise they
don't.
