Example solution: Find, Fix, Verify

Instructor reference; attempt the student worksheet before opening the answer key.

Use the corrected application and its REMEDIATION.md to explain the dependency changes, then compare the tests and before/after reports. The application code is unchanged; the exercise repairs its dependencies.

Choose one package-manager track

The links point to the existing runnable solutions, rather than duplicate copies. Each solution includes the corrected manifest, lockfile, application, tests, and a worked remediation explanation. Use the track instructions for installation and scanning commands.

Track	Corrected application	Explanation	Run instructions	Captured reports
npm	Solution	Remediation	Instructions	Before/after
pnpm	Solution	Remediation	Instructions	Before/after
Yarn Classic	Solution	Remediation	Instructions	Before/after
Yarn Berry	Solution	Remediation	Instructions	Before/after
Bun	Solution	Remediation	Instructions	Before/after

Verify and teach the example

1. Read the selected track's instructions and remediation explanation.
2. Run the supplied tests and application, then scan using that track's documented commands.
3. Compare actual results with the captured reports and explain any differences. Advisory data changes; do not grade against a permanently fixed finding count.
4. Use the walkthrough and rubric when evaluating students' reasoning. Other justified and verified repairs can be valid.

Sharing with students

These solutions are public. For assignments where you want to withhold answers, distribute a student-only export, not the full repository. The export excludes instructor solutions and captured reports. Students may still find the public repository, so adapt graded tasks accordingly.
