Lesson 11 of Track 7 (Git Workflow: From Solo to Multi-Agent Teams). Two surgical tools every working developer reaches for. Cherry-pick copies a single commit from one branch onto another, the canonical way to backport hotfixes. Stash saves in-progress work without committing, the safety net for context switches. By the end of L11 you can backport a fix across branches, set aside dirty work to handle an emergency, and recover safely from both.
