**Outcome:** done
**Changed:** src/calculator.py:11-18
**Verified by:** python3 -m compileall -q src — passed; python3 -c with five acceptance assertions — passed. make verify fails because tests/ directory does not exist.
**Findings:** clamp(value: int, low: int, high: int) -> int added at src/calculator.py:11 with no docstrings or comments. File header at src/calculator.py:1 is present. All functions use full int type annotations.
**Open:** Test writer (sveta) should create tests/ directory and add unit tests for clamp.
**Confidence:** high

Outcome: done
Changed: src/calculator.py:11-19
Verified by: `make verify` — exit 0, "verification passed"
Findings: src/calculator.py now defines multiply(left: int, right: int) -> int and divide(left: int, right: int) -> int.
divide raises ValueError('division by zero') when the divisor is zero, using integer floor division (//) to preserve the int return type.
Open: none
Confidence: high — both functions added, header preserved, no comments/docstrings, full type annotations, verify passed.
