Outcome: done
Changed: app/__init__.py:11-14 | src/calculator.py deleted
Verified by: `make verify` — passed, 67 tests, no failures, zero warnings
Findings:
- src/calculator.py deleted — was a near-exact duplicate of src/typosaurus_sandbox/domain/calculator/operations.py
- app/__init__.py imports now use typosaurus_sandbox.domain.calculator (canonical module) instead of src.calculator
- All 67 existing tests pass with no regressions
- Flask app continues to serve its HTML frontend via the same routes
Open: none
Confidence: high — syntactic correctness verified by `py_compile`, functional correctness verified by `make verify` passing all 67 tests
