Spend longer whenever you need.</p><p>Use a supported target compiler, framework headers, and runtime. Record the exact versions. Compile one minimal binding, execute it on the target, and verify the result and ownership behavior. A Linux Object Pascal class test cannot establish that an Apple framework bridge works. If the target is unavailable, complete the design analysis and label execution untested. Keep a separate portable core so the rest of your project remains testable.</p><h3>Practice and evidence</h3><p>Keep three notes: your prediction, the actual result, and why they match or differ. The completion check grades understanding; the practice task builds skill.</p><p><a href="https://docs.freepascal.org/daily/doc/ref/refse74.html">Language reference</a></p></html>
