Deterministic stem model
Each value is rounded once to the selected leaf unit, converted to an integer leaf index, then decomposed as stem × 10 + leaf. Negative values use mathematical floor division, leaving leaves 0–9 and an unambiguous text key. Duplicates remain duplicates and leaves sort ascending. Bounds: 10,000 finite observations and 200,000 input characters.
