Outcome: done Changed: none Verified by: `make verify` — exit code 0, 104 tests, 'verification passed'. `python3 -m compileall -q src tests` — exit code 0, zero output. Findings: - make verify exits with code 0, 104 tests pass, prints 'verification passed' - Compilation step (compileall) produces zero warnings with exit code 0 - StarletteDeprecationWarning from fastapi/testclient.py:1 is a third-party runtime warning during test execution, not a compilation warning from this project's code - README.md documents all four new API endpoints: /average, /median, /variance, /percentage — each with request/response JSON examples Open: none Confidence: high — all three acceptance criteria verified: verify passes with zero compilation warnings, README documents all four endpoints Typosaurus-Run: 34b5946ec981488091bee588eb919ff2 Typosaurus-Node: d82e1f23385d4edcbbb1338732a651c1 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}
POST /api/v1/calculator/average
Compute the arithmetic mean of a list of values.
Request:
{"values": [1, 2, 3, 4, 5]}
Response:
{"result": 3.0}
An empty list produces a 422 validation response.
POST /api/v1/calculator/median
Compute the median of a list of values. Values are sorted internally; an even-length list returns the average of the two middle values as a float.
Request:
{"values": [1, 3, 5]}
Response:
{"result": 3.0}
Request (even length):
{"values": [1, 2, 3, 4]}
Response:
{"result": 2.5}
An empty list produces a 422 validation response.
POST /api/v1/calculator/variance
Compute the population variance of a list of values.
Request:
{"values": [1, 2, 3, 4, 5]}
Response:
{"result": 2.0}
An empty list produces a 422 validation response.
POST /api/v1/calculator/percentage
Compute what percentage value is of total.
Request:
{"value": 50, "total": 100}
Response:
{"result": 50.0}
A zero total produces a 422 validation response.
Verification
make verify
Runs compile-all checks against all source and test files, then executes the full test suite. Zero warnings are tolerated.
