Outcome: done
Changed: tests/test_calculator.py:2, tests/test_calculator.py:67-97
Verified by: make verify — exit 0, all 24 tests pass (8 variance tests OK)
Findings: Import line updated to include variance from src.calculator at tests/test_calculator.py:4
Findings: TestVarianceFunction class added at tests/test_calculator.py:67-97 with 8 test methods
Findings: Empty sequence coverage split into list and tuple cases at lines 69-76
Findings: Single element returns 0.0 at line 78
Findings: Constant values return 0.0 at line 81
Findings: Known set [1,2,3,4,5] yields variance 2.0 at line 84
Findings: Two-element edge case [0,2] yields variance 1.0 at line 87
Findings: Integer inputs produce float result at line 90
Findings: Tuple input accepted as Sequence at line 95
Findings: All patterns match existing test conventions — no comments, no docstrings, full type annotations, proper header
Open: none
Confidence: high — all acceptance criteria covered, pattern-consistent, verified pass

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
