✂️ The Messy Commit0/6

📖 Story

Monday morning your tech lead pings you: 'Can you split that PR? It touches auth AND the cart — I can't review both at once.' In Git this means reset, stash, branch, cherry-pick chaos. In jj you just split.

Check the log: jj log

You have one change called 'Add auth and cart' that added two unrelated files. Your lead wants two separate changes. Let's split it.

● Check the log: `jj log`

○ Split the change: `jj split wmess02`

○ Describe part 2 (WC's parent): `jj describe -m "Add cart" -r @-`

○ Describe part 1: `jj describe -m "Add auth"`

○ Verify: `jj log`

○ Bonus — squash a fixup: `jj squash`
