A Copilot Chat session has drifted through several unrelated investigations and now applies an old requirement to a new task. What should the developer do?

1. Rename the target file and repeat the same ambiguous request.
2. Append the full history from several more unrelated tasks to increase context.
3. Ask for a longer answer without correcting the requirement.
4. Start a focused conversation or remove irrelevant context, then restate the current requirements and attach the needed files.
