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 Typosaurus-Run: d4f7c095ea9d49c69663ae6d01a21513 Typosaurus-Node: 9fe1a5bb3c164f6eb359366ca55b1067 Typosaurus-Agent: @sveta Refs: #15

typosaurus-sandbox
Sandbox for Typosaurus end-to-end verification.
A FastAPI application serving arithmetic operations over HTTP with JSON request/response bodies.
Configuration
The application uses a single .env.json file at the project root as its central point of truth
for configuration. Defaults are plug-and-play and require no setup:
{
"host": "127.0.0.1",
"port": 8000
}
When no .env.json is present, the application starts with these defaults. To customise, create
.env.json in the project root and populate only the keys that differ.
Usage
Start the server
python -m typosaurus_sandbox
The server listens on http://127.0.0.1:8000 by default.
Health check
GET /health
Response:
{"status": "ok"}
API endpoints
All calculator endpoints accept POST requests with a JSON body and return a JSON response.
POST /api/v1/calculator/add
Add two integers.
Request:
{"left": 3, "right": 5}
Response:
{"result": 8}
POST /api/v1/calculator/subtract
Subtract the right integer from the left.
Request:
{"left": 10, "right": 3}
Response:
{"result": 7}
POST /api/v1/calculator/clamp
Clamp a value between a low and high bound.
Request:
{"value": 15, "low": 0, "high": 10}
Response:
{"result": 10}
Boundaries are inclusive. A low > high combination produces a 422 validation response.
POST /api/v1/calculator/clamp-to-byte
Clamp an integer to the byte range [0, 255].
Request:
{"value": 300}
Response:
{"result": 255}
Verification
make verify
Runs compile-all checks against all source and test files, then executes the full test suite. Zero warnings are tolerated.
