See modified diagram below. Are the annotations I have added (and the
name change) any help ?

No, it also contains a complete unmodified copy of the upstream code.
(Except that if upstream had a debian/ directory, it is completely
replaced.) Perhaps this is the wrong name. Let's try
`merging-baseline'
For `3.0 (quilt)' the merging-baseline branch contains roughly what
you would get if you untarred the origs and the debian.tar.gz, and
then deleted all the patches without applying them.
Not shown on the diagram is the commit `add patch queue to
debian/patches', which would be needed for `3.0 (quilt)'. This is
because the diagram is in terms of a sane source format, not `3.0
(quilt)'. For use with quilty sources, there would be such a commit
(probably dgit-generated) on top of the actual upstream change
commits:
------/--A!----/--B3!--%--/--> interchange view
/ / / with debian/ directory
% % % all upstream changes applied
/ / / 3.0 (quilt) has debian/patches
/ 2* 2*
/ / /
2* 2 2
/ / /
1 1 1 `merging-baseline' branch
/ / / unmodified upstream code
---p-----p--A----p--B--C--> plus debian/ (but no debian/patches)
/ / /
--#-----#-------#-----> upstream
Key:
1,2,3 commits touching upstream files only
A,B,C commits touching debian/ only
B3 mixed commit (eg made by an NMUer)
# upstream releases
-p- special merge, takes contents of debian/ from the
/ previous `merging-baseline' commit and rest from upstream
-/- pseudomerge; contents are identical to
/ parent lower on diagram.
% dgit-generated commit of debian/patches.
`3.0 (quilt)' only; dropped by rebase tool.
* Maintainer's HEAD was here while they were editing,
before they said they were done, at which point their
tools generated [% and] -/- commit[s] to convert to
the fast-forwarding interchange branch. (Maybe the
tooling is simply `dgit push'.)
! NMUer's HEAD was here when they said `dgit push'.
Rebase branch launderer turns each ! into an
equivalent *.
