Roadmap revision
Example application update
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟠 High · up to This PR changes cookie emission and session configuration, but the current head still permits cookie-attribute injection, can fail response generation from an invalid Session argument, and can break CSRF validation over HTTP. The example server also exposes unauthenticated routes on all interfaces, and the public option rename can break existing callers. These issues should be fixed or explicitly accepted before merging.

Use the runtime keyword samesite consistently for session cookies.
The session code passes same_site, but Response.set_cookie accepts samesite. When the session changes, this raises TypeError before the response is returned and no Set-Cookie header is added. Rename the call to samesite or add compatible support for same_site before marking this complete.

Make CSRF cookie security configurable.
This call omits secure, so Response.set_cookie emits a Secure cookie. Over HTTP, clients do not send that cookie on the next unsafe request. CsrfProtect then generates a new token and rejects the submitted token from the prior response.
Add a cookie_secure option that defaults to True, and pass it explicitly to set_cookie.

Validate or serialize all cookie fields before formatting the header.
name, value, path, domain, and samesite are inserted into cookie syntax without escaping. If an application passes value="abc; Domain=example.com", the emitted header contains an extra cookie attribute. This is cookie-attribute injection.
Use a cookie serializer, or reject cookie delimiters and restrict samesite to supported values before building the header.

Run this case through the HTTP test fixture.
Direct Response inspection bypasses server header serialization and client cookie handling. Use the session-scoped server fixture and requests to assert that the client receives both Set-Cookie values.
As per coding guidelines, “Tests use a session-scoped fixture that starts a real HTTP server” and “Use requests library for HTTP assertions in tests.”

Renumber the remaining Important priorities.
Line [79] changes the heading to priority 13, but the Important section currently jumps from priority 9 to priorities 13 and 14. Rename the remaining entries to maintain contiguous priorities, or document that the gaps are intentional.

Name the first handler parameter request.
tests/app.py is under tests/**/*.py, where the repository requires request as the first argument. Rename _ in all three lambdas.
Proposed fix
- .route(get("/", lambda _: ""))
- .route(get("/user/{id:int}", lambda _, id: str(id)))
- .route(post("/user", lambda _: ""))
+ .route(get("/", lambda request: ""))
+ .route(get("/user/{id:int}", lambda request, id: str(id)))
+ .route(post("/user", lambda request: ""))📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
