A local repository with a readable change history, two merged contributions, a resolved practice conflict, and an evidence-based review note.

Keep your working files in your own notebook or software. Save a private description, checklist, and work link in My Proof.

What to include

  • Base and clarification commits.
  • Review note grounded in an actual diff.
  • Merged independent title contribution.
  • Resolved hours conflict using the approved policy.
  • Final files, history evidence and recovery note.

Review and revise

Use these criteria to check your work and choose what to improve.

  • History records meaningful changes.
  • Final notice matches all four required lines.
  • Conflict resolution retains unrelated content.
  • Review and recovery claims are accurate.

The idea in everyday life

The practice cafe project is ready for local review. No public push is required.

The idea

A handoff lets another person identify the current state, the reasons behind it, and the next safe step.

Follow along

Hand off a reviewable repository — guided practice

Package a project with a truthful review and recovery plan.

Continue after lesson 5. Final notice: Neighborhood Repair Cafe; Hours: 11-13; Bring: one small unplugged item; Access: step-free entrance.

  1. 1. Complete the note

    Extend review.md with final hours, the conflict decision, and a list of checks actually performed.

    You should see: The note names the approved 11-13 choice and four final lines.

    Handoffs explain judgment as well as files.

  2. 2. Record the handoff

    Stage review.md and commit it.

    git add review.md
    git commit -m "Document review and approved hours"

    You should see: The repository includes the notice and review note.

    The handoff itself becomes part of project history.

  3. 3. Inspect a past version safely

    Use git show HEAD:notice.txt and git log --oneline. Do not rewrite history.

    git show HEAD:notice.txt
    git log --oneline

    You should see: Current notice is displayed and earlier reasons are visible.

    Read-only inspection avoids overwriting current work.

  4. 4. Write the recovery approach

    Add to your external submission: for a shared mistaken commit, first inspect its diff and dependencies, then create a correcting commit or reviewed revert; do not force-push.

    You should see: The plan preserves a review trail and acknowledges review before undo.

    Recovery can affect later work, so it needs context.

Now change one thing

A review records 5 checks; 2 were planned but never run. Enter the number that may be reported as completed.

Your work

What to finish

A local repository evidence package with the final notice, review.md, history evidence and recovery note.

Common mistake

Watch for this

Treating an untested recovery command as safe for a shared production repository.
