# M04-L03 exercise — Capture project and hardware facts

Starting checkpoint: CP02. Figures: SS09-01, SS09-02, D08.

In a new CP02 copy, prepare three sourced rows: board identity, memory variant, and one explicit physical-revision unknown. Create a requirements document with the teaching alert threshold labeled as a planned later feature, keeping it separate from hardware facts and current baseline behavior. Link the documents from the README. Submit the context files and source-check note. If a source cannot be opened, record the access limitation and distinguish supplied reference material from your own live check.

## 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.
