Spend longer whenever you need.</p><p>A useful test compares a result with a requirement. The planner must never report negative remaining work for its stated nonnegative input domain. Run the starter, then deliberately remove the protection for completed counts above total. At least one check should fail. Restore it. Add two named study tasks, a summary, and boundary cases. Save the source and evidence on Agila Forge. Explain every line, including anything suggested by AI.</p><p><code>Main</code> is the entry method inside <code>Program</code>. <code>Console.WriteLine</code> prints a line. A class instance can have several references to the same object; assigning a reference does not clone the object.</p><pre><code class="language-csharp">using System;
