35464c207a test(sveta): Write API integration tests for calculator endpoints 
Outcome: done
Changed: tests/test_api.py:53-68,75-85,90-98 — added clamp low>high, missing-field, and subtract missing-field tests; src/typosaurus_sandbox/presentation/api/v1/calculator.py:2,51-55 — added HTTPException import and ValueError catch in calculate_clamp
Verified by: `make verify` — exit 0, 47 tests OK, zero warnings, zero compile errors
Findings:
- tests/test_api.py now contains 22 integration tests covering all five endpoints with success, validation errors (missing fields, wrong types), and the clamp low>high ValueError boundary.
- clamp low>high error is returned as 422 via HTTPException in the route handler, matching the acceptance criterion.
- All 47 tests (25 unit + 22 integration) pass with zero warnings.
Open: none
Confidence: high — all acceptance criteria addressed, all tests pass, verification gate passed

d36b9593d0 feat(nadia): Implement FastAPI application with calculator endpoints

Outcome: done

  - tests/test_calculator.py:1-95
  - tests/test_api.py:1-120
  - Makefile:2
  - CLAUDE.md:4-23
Verified by: `make verify` — exit 0, 42 tests OK, zero warnings
Findings:
  - FastAPI application created at src/typosaurus_sandbox/app.py with App importable as `from typosaurus_sandbox import App`.
  - Calculator HTTP API router at src/typosaurus_sandbox/presentation/api/v1/calculator.py with endpoints: POST /api/v1/calculator/add, POST /api/v1/calculator/subtract, POST /api/v1/calculator/clamp, POST /api/v1/calculator/clamp-to-byte.
  - Health endpoint at GET /health implemented directly on App in src/typosaurus_sandbox/app.py.
  - All endpoints use Pydantic models for request validation and response serialization (AddRequest, SubtractRequest, ClampRequest, ClampToByteRequest, IntResult, FloatResult).
  - 42 tests pass (16 unit tests for calculator function
