Outcome: done
Changed: tests/__init__.py:1, tests/test_calculator.py:1-86
Verified by: `make verify` — exit 0, "verification passed", Ran 16 tests in 0.001s, OK
Findings: tests/ directory created at ./tests/ with __init__.py (header only) and test_calculator.py (16 tests for clamp).
Findings: All 16 clamp tests pass under `make verify`: value below low, above high, in range, equals low, equals high, low>high ValueError, negative values, float below/above/in-range/equals-boundary, float low>high ValueError, large values, -inf/inf boundaries, and NaN.
Findings: clamp is typed as (value: int, low: int, high: int) -> int; float and inf/NaN tests pass because Python does not enforce type hints at runtime.
Open: none
Confidence: high - all 16 tests pass, all acceptance criteria covered, make verify passes
