Module 1 – Choose, reproduce, and test
Record a reproducible baseline
15-minute session: read for 3 minutes, trace for 3, experiment for 7, and complete the check for 2. Spend longer whenever you need.
A test result is tied to a commit, toolchain, target, and command. Record git rev-parse HEAD, compiler versions, and make test output before editing. If the baseline fails, investigate that failure before attributing it to your patch. Redact secrets from logs.
Your experiment
Create a baseline report with the exact command and observed result. Mark any target you did not run as untested.
Practice and evidence
Keep three notes: your prediction, the actual result, and why they match or differ. The completion check grades understanding; the practice task builds skill.
