typosaurus e00a2db81b feat(nadia): Build research package foundation: config, rsearch-only HTTP client, TTL caches
Outcome: done
Changed: src/typosaurus_sandbox/research/__init__.py:1-28, src/typosaurus_sandbox/research/config.py:1-43, src/typosaurus_sandbox/research/envelopes.py:1-214, src/typosaurus_sandbox/research/cache.py:1-48, src/typosaurus_sandbox/research/client.py:1-196
Verified by: verify() -> "make verify" exit_code 0, compileall OK, 104 tests OK, "verification passed" (pre-existing StarletteDeprecationWarning from fastapi.testclient import in tests/test_api.py, not introduced by this change); live smoke: web/images/ai search, chat with usage, describe GET, describe_raw POST, search-cache hit, content-cache fill+hit all passed; deep envelope parsing validated against captured live response (model, rounds, sources, grades, queries_tried)
Findings:
- RsearchClient: search(query, source, count, content, type, deep, ai, cache), chat(prompt, system, json_mode, cache), describe(url), describe_upload(bytes, filename, mime_type), describe_raw(bytes, mime_type), get_cached_content(url); failures raise RsearchError(message, status_code) with server error text extracted (504 detail, success:false error).
- Caches: search 300s TTL keyed by sorted urlencoded params; content 86400s keyed by result URL; describe 86400s keyed by url:/hash:sha256; threading.Lock guarded; hit/miss logged DEBUG.
- ResearchConfig.load reads the "research" key of .env.json; defaults base_url https://rsearch.app.molodetz.nl, timeout 30s, deep timeout 180s, max_concurrency 8, default_count 10.
- HTTP is stdlib-only

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.
