Outcome: done Changed: tests/test_calculator.py:5, tests/test_calculator.py:213-260 Verified by: `make verify` — passed, 104 tests, 0 failures Findings: - tests/test_calculator.py:5 — added `percentage` to the import from `typosaurus_sandbox.domain.calculator` - tests/test_calculator.py:212-260 — added `TestPercentageFunction` class with 11 unit tests covering: success cases (half, quarter, zero, exceeds total), negative inputs (negative value, negative total, both negative), float inputs, total-zero error paths (integer and float zero), and return type verification (integer inputs yield float result) - All 104 tests pass under `make verify` with zero failures (93 existing + 11 new percentage unit tests) Open: none Confidence: high — all acceptance criteria met; API tests were already completed by sibling node (expose-missing-operations); percentage unit tests now complete unit test coverage; verification passed Typosaurus-Run: 34b5946ec981488091bee588eb919ff2 Typosaurus-Node: f085f049a7424a628ea68af395e24072 Typosaurus-Agent: @sveta Refs: #28

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.
