M04-L01 exercise — Write Markdown that renders correctly

Starting checkpoint: CP02. Figures: SS08-01, SS08-02.

Create a practice README with one title, two useful headings, an ordered procedure, the supplied replay command, a relative hardware link, and the three-column evidence table. Preview it. Introduce and repair one missing fence. Follow the link from the preview. Submit the file and a note naming the fault, correction, and actual checks. Do not mark command execution passed unless you ran it successfully. Recovery: reopen the preserved CP02 copy if you lose track of your changes.

Completion record

Record the checkpoint, changed files, checks actually performed, results, and open limitations. Keep expected output distinct from observed output. Preserve the starting copy and review the final diff before considering the artifact complete.
