Different text states need different protections. Keep identifiers, separators, blanks, and capitalization tied to an explicit contract.

Arrange in the correct order
  1. 1. Keep the boundary examples as regression tests
  2. 2. Compare actual values with expected meaning
  3. 3. Apply the smallest defined transformation
  4. 4. Prepare normal, blank, mixed-case, and separator examples
  5. 5. State allowed inputs and intended normalization
