Is there any possibility to graft/rebase a change set from say the
default branch to another named branch, say main, *without* changing the
hash?
No, because the branch name is part of the hash calculation.
Ok, that makes sense.

I can rebase them, (with or without evolve enabled) but the rebased changeset
gets a new hash which means that if I push it, it will confuse git
users.
It sounds like what you want is to have the resulting git-hash equal,
not to have the Mercurial-hash equal. This could in theory be possible
(because the branch name is not part of the hash-generation in git), but
I do not know whether it is possible in practice.
I just realised with *evolve enabled*, the rebase results in no githash at
all, a bug?

Hg log  -G --follow --template "\x1B[33mcommit {rev}:{gitnode}\nAuthor: 
{author}\nDate: {date|rfc822date}\n\n{desc}\n{nofiles}\n"

Before the rebase gave

    First commit to the main branch

In any case this is not good at all.
I could force a push, but this would make things worse

Any comments from the hg-git team?

Yes! hg-git won't convert to Git unless you tell it to do so (using the `gexport` command) or it is really needed (push). Therefore there is no corresponding Git hash known yet.

So, please run `hg gexport`. Is it still the same?

Also, Heptapod has been using hg-git, evolve and topics together since day 0.


Best,
