Run linting and formatting before committing.
The coding guidelines require that all files matching api/**/*.py must be formatted and linted using ruff format followed by ruff check --fix, with all errors fixed before committing. The PR objectives confirm that linting and formatting checks have not yet been run locally. Please run these tools and resolve any issues.

Fix broken import: health_router module does not exist.
The test imports from oss.src.routers.health_router import router (line 4), but this module does not exist in the codebase. The import will fail immediately with an ImportError. The /health endpoint is already inlined in api/entrypoints/routers.py:1130 as a direct FastAPI route.
Additionally:
- Path mismatch: The test GETs
/health/(with trailing slash), but the production endpoint is registered as/health(no trailing slash). These are distinct routes in FastAPI. - Formatting: The file requires
ruff formatto meet code standards per theapi/**/*.pyguidelines.
Either update the test to verify the endpoint from entrypoints/routers.py directly, or remove this test if the health endpoint is intentionally not tested at the router level.

🌐 Web query:
FastAPI trailing slash behavior redirect_slashes
💡 Result:
In FastAPI, the redirect_slashes parameter controls how the application handles URLs with or without a trailing slash [1][2]. This parameter is available on both the FastAPI application class and the APIRouter class [1][2]. Behavior and Configuration: - Default Behavior: By default, redirect_slashes is set to True [1][2]. If a client requests a URL that does not match the trailing slash status of a defined route (e.g., requesting /items when only /items/ is defined), FastAPI will automatically issue an HTTP 307 Temporary Redirect to the URL with the trailing slash [2][3]. - Disabling Redirects: To prevent this redirect, you can set redirect_slashes=False when initializing your FastAPI app or APIRouter [1][4][5]. Note on Alternative Approaches: Because setting redirect_slashes=False simply stops the redirect without automatically mapping the alternate URL to the same handler, some developers implement custom solutions to support both paths (with and without a slash) for the same endpoint [4][6]. This is often achieved by creating a custom APIRouter subclass that overrides add_api_route to register both the path and its alternate (adding or removing the trailing slash) [4][6]. As of June 2026, there is no built-in, configuration-based feature in the core FastAPI library to natively ignore trailing slashes (i.e., make them equivalent without a redirect) without manually handling the routing or using community-driven workarounds [7][5]. [1][2][3]

Fix missing health_router module and correct the endpoint path.
The test imports from oss.src.routers.health_router, but this module does not exist in the codebase. Additionally, the test requests GET /health/ (with trailing slash) while the production endpoint in api/entrypoints/routers.py:1130 is defined as GET /health (without trailing slash). By default, FastAPI treats these as distinct routes and responds with a 307 redirect rather than a direct match.
Create the health_router.py module with a route matching the production endpoint (without trailing slash), or update the test to request /health without the trailing slash.

Summary
This PR adds a unit test for the FastAPI health router.
The test creates a FastAPI application, includes the health router, sends a request to the
/health/endpoint, and verifies that:{"status": "ok"}.Testing
Verified locally
/health/endpoint returns the expected status code and response body.Added or updated tests
