X-<  Somehow I missed the "3" in "1/3" above and did not look beyond
this first patch.

I am not sure about that.  For merge strategies "exit with 1 iff you
left the conflict in the index" is the contract between "git merge"
frontend and the strategies backend; if a similar contract is needed
between the sequencer and its users, it is good to follow the same
pattern for consistency.  The resulting index and/or the working
tree may or may not match the contents recorded in the HEAD commit
but without the backend telling the caller, the caller cannot tell
if the difference was from before the operation or created by the
operation.
