internal/crc_test.go:92

• Duplicate validation logic exists - the same ValidateCRC24 call is performed both with assert.True and the old manual assertion pattern. The manual assertion (lines 89-92) should be removed since it's redundant with the testify assertion above.

	assert.True(
		t,
		ValidateCRC24(data, checksum),
		"Expected checksum validation to be true for pre-determined valid checksum, but got false.",
	)
	valid := ValidateCRC24(data, checksum)
	if !valid {
		t.Errorf("Expected checksum validation to be true, but got false.")
	}
