• [nitpick] The PR description mentions testing concurrent updates, but this test only covers task creation. Consider adding scenarios for concurrent updates or adjusting the PR description to match the implemented test.

func (s *TaskConcurrencyTestSuite) TestConcurrentCreateTask() {

• fmt.Sprintf is used but the fmt package is not imported, which will cause a compile error. Add import "fmt".

	suite.dbFilePath = fmt.Sprintf("%s/testdb_%d.db", os.TempDir(), time.Now().UnixNano())
