A current frontier editor-agent told to "merge X into Y" resolves the
conflict and completes the merge in one turn, so the learner never sees a
marker. The old Part C assumed Git would stop and ask. Rework the lab into
a three-beat sequence: witness the conflict once (agent stop-on-conflict
idiom, as in Module 26), undo it with `git merge --abort`, then let the AI
merge for real and auto-resolve while the learner does the one job still
theirs: verify with `git diff` after every merge.
Updates the matching surfaces so they tell one story: learning objective
#4, the Merge-conflicts key concept, the AI-angle bullet, the
Where-it-breaks bullet, Check-for-understanding, the blog mirror, and the
make-conflict.sh on-screen guidance (read the markers yourself first).
