Wait for the free limit to reset to keep reviewing this public repository. How can I continue?After more reviews become available, a review can be triggered using the To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews. How do review limits work?CodeRabbit enforces per-developer PR review limits within each organization. For paid Pro and Pro+ reviews, CodeRabbit uses a developer's included PR review attempts over the past 7 days to set the current hourly allowance. At typical activity levels, the full plan allowance applies. Higher sustained activity can lower the allowance until earlier attempts leave the 7-day window. Please refer docs for additional details.

📝 WalkthroughWalkthroughThe PR adds CSRF middleware and template helpers, propagates response header errors, replaces unsafe route lifetime handling with owned route data, updates public type declarations, and documents project architecture and request processing. ChangesRequest safety and framework integration
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to The PR introduces CSRF and CORS behavior changes, but the current head still mishandles response headers, emits invalid multi-origin CORS headers, stops processing after CORS errors, and contains broken CSRF integration paths; the stricter session-cookie default can also break OAuth/SSO callbacks. These are concrete correctness, security, and availability regressions, so the PR is not safe to merge until fixed. Sequence Diagram(s)sequenceDiagram

Inline comments:
In `@AGENTS.md`:
- Line 110: Update the two diagram code fences at the referenced documentation
sections to include an explicit language identifier such as text on each opening
fence, resolving markdownlint MD040 while preserving the diagram contents.
- Around line 191-192: Remove the duplicated csrf_token bullet in the documented
injected values list, keeping a single entry with its existing condition.
In `@oxapy/__init__.py`:
- Line 233: Update the session-cookie configuration near the SameSite attribute
to retain SameSite=Lax as the default, or expose a configurable policy that
defaults to Lax; ensure OAuth and SSO callback navigations continue receiving
the session cookie.
- Line 389: Update CsrfProtect.__call__ and _session_middleware to rename the
continuation parameter from next and add appropriate type hints, then update the
continuation invocation in middleware.rs to pass it positionally rather than
with next=next; preserve the existing middleware behavior.
In `@oxapy/__init__.pyi`:
- Line 1415: Update the CsrfProtect stub declaration to include the
runtime-supported safe_methods parameter with its correct type and default,
preserving the existing parameter order and return annotation.
In `@src/cors.rs`:
- Around line 113-120: Update Cors policy application around apply_headers to
accept the request Origin, emit exactly that origin only when it matches the
configured allowed origins, and add Vary: Origin for dynamic selection; never
join multiple origins into Access-Control-Allow-Origin. Validate or reject
wildcard origins when allow_credentials is enabled, while preserving the
existing method, header, credential, and max-age headers.
In `@src/lib.rs`:
- Line 540: Update the request-processing loop around apply_cors so a CORS
failure is converted into an error response and sent through response_sender for
the current request, rather than propagated with ?, then continue processing
subsequent requests.
- Around line 651-670: Fix the exported csrf_input binding by implementing it
instead of leaving the reachable Rust stub as todo!, or remove its Rust export
if the helper is provided elsewhere. If retaining the Rust CsrfProtect export,
rename the Rust function to csrf_protect while preserving the existing
Python-facing CsrfProtect API.
In `@src/response.rs`:
- Around line 167-171: Update the HeaderValue parsing in insert_header and the
other affected header-insertion paths to parse the supplied value argument
rather than key. Preserve HeaderName parsing from key and ensure all call sites,
including Set-Cookie and CORS handling, insert the parsed header value.
Apply the same fix in `@oxapy/__init__.py` around lines 419 - 429.
In `@src/templating.rs`:
- Around line 124-129: Update both CSRF template examples in oxapy/__init__.py
at lines 315-318 and 353-360 to call csrf_input with the token keyword argument
and apply the safe filter. The registration in src/templating.rs lines 124-129
requires no direct change because its lambda already accepts the token keyword.
In `@TODO.md`:
- Around line 95-99: Update the completed TODO checklist item to use the exact
exported middleware name, CsrfProtect, instead of CsrfMiddleware, and verify the
name against the public API stubs and implementation.
