typosaurus c0a59b4138 feat(nadia): Build content-type agnostic pipeline with bounded asyncio worker pool
Outcome: done
Changed: src/typosaurus_sandbox/research/pipeline.py:1-280 (new), src/typosaurus_sandbox/research/client.py:30-52,98-99,124-148, src/typosaurus_sandbox/research/__init__.py:21-49
Verified by: make verify -> exit_code 0, compileall OK, 195 tests OK, "verification passed" (pre-existing StarletteDeprecationWarning from tests/test_api.py); live smoke: web/images/chat via one pool (3 ok, urls=19, queries=92, contents=10), repeat web item cache_hit=True, empty query -> RsearchError 400 handled, pool survived
Findings:
- ResearchPipeline uses asyncio.Semaphore(max_concurrency, default 8); pool size logged INFO in run(); run(AsyncIterator[WorkItem]) = bounded queue (pool*4) + pool_size workers with None sentinels; process(item) is the public semaphore-guarded path.
- WorkItem(kind: web|images|describe|chat, value, deep=False, ai=False); web -> search(content=True), images -> search(type="images") without deep/ai, describe -> describe(url), chat -> chat(prompt); endpoints /search,/describe,/chat.
- extract_response() handles SearchResponse (results, ai_response, deep sources/markdown), ChatResponse.response, DescribeResponse.description in one function; apply_extraction() registers URLs, query seeds (title/description/extra/text with origin) and content fingerprints into QueryFrontier.
- client.py additive: _search_params() shared by search() and new search_cached()/describe_cached() probes so pipeline cache_hit is accurate; chat/deep cache hit from envelope fields cache

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.
