Outcome: done Changed: src/typosaurus_sandbox/presentation/api/v1/calculator.py — added imports (average, median, variance, percentage, logging), ValuesRequest model, PercentageRequest model, and four new endpoint handlers with logging and ValueError → 422 conversion tests/test_api.py — added 26 test cases across four new test classes Verified by: `make verify` — 93 tests, 0 failures, 0 new warnings Findings: - `ValuesRequest` model accepts `values: list[float]` and serves /average, /median, /variance - `PercentageRequest` model accepts `value: float, total: float` for /percentage - All four endpoints log at DEBUG level on invocation - Empty list (average, median, variance) and zero total (percentage) produce HTTP 422 with descriptive detail Open: none Confidence: high — 26 new tests pass, zero regressions, pattern matches existing endpoint conventions Typosaurus-Run: 34b5946ec981488091bee588eb919ff2 Typosaurus-Node: 644d226aefca431c81cf8be8a46d2070 Typosaurus-Agent: @nadia 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.
