Push the Integrated History
Local main now contains one clean merge of the receipt work and the colleague’s quantity work, while the bare origin still points to the earlier colleague tip. Moving origin’s main to the integrated local tip will preserve both sides.
Check the handoff before sending it
The plain git status report should say the tree is clean and local main is ahead of origin/main. The command git log --oneline origin/main..main uses the history range from the previous lesson to show what the push will add to origin: your two receipt --oneline option keeps each result to an abbreviated ID and its subject.
git status
git log --oneline origin/main..main
This review is about the history that will become shared. It does not predict a set of file uploads. Git will send any missing commit objects and then ask origin to move its
Push the safe result
The command git push uses the upstream relationship already configured for main. This time the bare origin’s current tip is an ancestor of the integrated local tip, so the update is a fast-forward and preserves everything origin already had:
git push
git status
After the successful push, Git also updates the local remote-tracking ref origin/main. Local main, local origin/main, and the bare origin’s main now name the same integrated commit. The separate colleague clone does not change automatically; its local main and its last-seen origin/main remain at the earlier colleague tip until someone works in that clone again.
The same git push was rejected in the previous lesson and accepted in this one. What changed?
That is a complete collaboration round trip: someone else’s work arrived, you inspected it, you combined it with your own without discarding either side, and you handed the result back. Every origin from now on receives both people’s work in one history.
None of it needed an account, a password, or a network connection. The only thing a hosting service would have changed is the distance between those directories.
