+# Git Quick Reference
+
+Standard git commands assumed known. This covers less common operations and JJ mapping.
+
+## Less Common Commands
+
+```bash
+git add -p <file>              # Interactive hunk staging
+git restore --staged <file>    # Unstage (preferred over reset)
+git switch -c <name>           # Create+switch (preferred over checkout -b)
+git reflog                     # Local HEAD history (recovery)
+git worktree add ../<dir> <branch>  # Parallel working directory
+git stash show -p stash@{0}    # Show stash diff
+```
+
+## Safety Reminders
+
+- Confirm before: `reset --hard`, `branch -D`, `push --force`, `clean -fd`
+- Recovery: `git reflog` + `git branch <name> <hash>`
+
+## Git to JJ Mapping
+
+| Git | JJ |
+|-----|-----|
+| branch | bookmark |
+| stash | `jj new` (checkpoint) |
+| worktree | workspace |
+| checkout/switch | `jj edit` |
+| commit --amend | `jj describe` or `jj squash` |
+| rebase | `jj rebase` (non-destructive) |
+| cherry-pick | `jj duplicate` |
+| merge | `jj new <rev1> <rev2>` |
