1.7 Journal: first entry in the vault

This is the first journal entry that lives where journal entries will live from now on. Create today's daily note in Obsidian (calendar icon, or Ctrl+P then "daily note") and fill in the four sections about this module. Some prompts, if the blank headings stare back:

Under what I did: which tools you installed, in what order, and the one that took longest.

Under what broke: something did. An installer, an auth flow, a command that failed the first time. Write what happened and how it ended, even if the ending was "typo, found it in five minutes." You're building the reflex of recording failure without embarrassment, because in this field failure is data.

Under what I learned: one thing about Git's mental model, in your own words. Explaining it to the page is how you find out whether you understood it.

Under open questions: anything that still feels like magic. Candid entries here become satisfying to cross off later. "Why does Git need a staging step at all?" is a great one; Module 10 makes the answer obvious.

Then close the loop with the rhythm from this module:

cd ~/git/lab-journal
git status
git add -A
git commit -m "journal: module 1 complete"
git push

Also tick Module 1 in Projects/lab-progress.md while you're in there. Watching that list fill up is a feature, not vanity.
