copyPlanForFork method
Copy a plan file for a forked session.
Unlike copyPlanForResume (which reuses the original slug), this generates a NEW slug for the forked session and writes the original plan content to the new file.
Implementation
Future<bool> copyPlanForFork({
required LogOption log,
required String targetSessionId,
}) async {
final originalSlug = _getSlugFromLog(log);
if (originalSlug == null) return false;
final originalPlanPath = '$plansDirectory/$originalSlug.md';
final newSlug = getPlanSlug(targetSessionId);
final newPlanPath = '$plansDirectory/$newSlug.md';
try {
await File(originalPlanPath).copy(newPlanPath);
return true;
} on FileSystemException {
return false;
}
}
