Merge Risk: 🟠 High · up to This change introduces a new outbound API gateway whose control-plane store can corrupt its own uniqueness indexes: a rejected duplicate alias or route rule leaves the previously working upstream or route unreachable for proxied traffic. Outbound destinations are not restricted, response guards and required-header policies do not actually take effect, IP-based rate limits apply to all callers at once, and upstream WebSocket handshakes can hang without a deadline. These issues should be addressed before merge because they affect availability, tenant policy enforcement, and outbound request safety. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 inconclusive)

64-76: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winMake the test distinguish streaming from full buffering.
TCP read boundaries do not preserve upstream flush boundaries. This loop only waits until all three events arrive. It also passes if the gateway buffers the complete response and sends it in one write.
Block production of the later chunks. Assert that the first event reaches the client before the test releases the remaining chunks.

- Around line 21-22: Update the query application flow so filtering occurs
before computing total, then paginate the filtered items; ensure total reflects
the number of matching resources rather than the unfiltered collection. Add an
assertion covering total for a filtered-list request.
In `@gears/system/oagw/oagw/src/api/query.rs`:
- Line 207: Replace the raw.split(" and ") logic in the query parsing flow with
a quote-aware tokenizer that splits on the conjunction only when outside string
literals. Preserve quoted text such as “research and development” as part of one
term while continuing to parse unquoted conjunctions normally.
In `@gears/system/oagw/oagw/src/config.rs`:
- Around line 14-15: Enforce ssrf_policy.enabled across every outbound
connection path, including DNS resolution and destination-address validation,
before any TcpStream::connect call in the proxy transport flow; reject
disallowed destinations such as private or link-local addresses even when
supplied by an authenticated tenant. Change the policy default from false to
true and update the E2E configuration to explicitly opt out, using
Upstream::validate and the transport connection helpers as the integration
points.
In `@gears/system/oagw/oagw/src/domain/store.rs`:
- Around line 420-437: Replace the non-atomic duplicate scan in the plugin
creation flow with a shared (tenant_id, plugin.name) to Uuid index, and claim
the key using the index entry API before inserting the Plugin record. Return the
existing conflict error when the key is already occupied, and ensure the index
claim and self.plugins insertion remain consistent on successful creation.

instead of only logging and continuing. Ensure the caller converts that error
into a gateway problem response before invoking build_response or constructing
the upstream response, while preserving the existing handling for guard
execution failures.
- Around line 570-574: Update the route-selection logic around best to store
each candidate’s chain_rank alongside depth and route. When selecting a
replacement, prioritize the lower chain_rank first, and use greater path depth
only when ranks are equal, preserving the selected descendant route and its
controls.
- Around line 873-878: Update the API boundary and both request handlers to
obtain and propagate the trusted peer address through to enforce_rate_limit,
then pass that address to ratelimit::scope_key instead of
ratelimit::UNKNOWN_CLIENT_IP for IP-scoped limits. Preserve the existing

In `@gears/system/oagw/oagw/src/proxy/ratelimit.rs`:
- Around line 153-155: Update the merge logic around the merged configuration
and iterator so a single rate-limit candidate retains its configured algorithm
instead of being overwritten by algorithm_default. Define explicit behavior for
differing candidate algorithms, preserving the selected algorithm when
candidates agree and handling conflicts according to the intended limiter
semantics.
In `@gears/system/oagw/oagw/src/proxy/transport.rs`:
- Line 267: Replace std::mem::forget(driver) with drop(driver) in the request
task flow, preserving the existing detached Tokio task behavior without leaking
the JoinHandle allocation.
In `@gears/system/oagw/oagw/src/proxy/ws.rs`:
- Around line 60-62: Wrap the tokio_tungstenite::client_async handshake in
tokio::time::timeout using the existing timeout value, and map both elapsed-time
and handshake errors to OagwError while preserving the current success handling.
- Around line 144-148: Update the WebSocket upgrade flow around WebSocketUpgrade
and upstream_response to read the upstream Sec-WebSocket-Protocol header and
pass its value to set_selected_protocol before calling on_upgrade. Preserve the
existing status handling and response header behavior, and only set the selected
protocol when the upstream header is present.
In `@gears/system/oagw/oagw/tests/management.rs`:

post-consumption token balance, while preserving the existing behavior when

- Around line 64-76: Update the streaming test around the socket read loop to
gate production of the second and third upstream chunks, then assert that the
first event is received before releasing those gates. Ensure the test still
verifies all three events afterward, distinguishing incremental forwarding from
full-response buffering.
- Around line 132-133: Update the connect_async assertion in the streaming test
to inspect the returned tungstenite error and extract the HTTP response rather
than accepting any failure. Assert the response has the expected HTTP status and
gateway error headers, while preserving the expectation that the WebSocket

- Around line 70-75: Update the list_upstreams, list_routes, and list_plugins
handlers so filtering, ordering, skipping, and limiting occur on model values

default_circuit_breaker_window_secs—instead of duplicating their literal values.
Preserve the current defaults for allow_http_upstream and ssrf_policy.
In `@gears/system/oagw/oagw/src/domain/model.rs`:
- Around line 761-767: Define constants for the auth, guard, and transform

Calculate total after filtering and before pagination.
query.apply(items) performs filtering and pagination together, but Line 21 records the unfiltered item count. A request such as $filter=enabled eq true can return count: 2 and total: 3, although total is documented as the number of matching resources.
Separate filtering from pagination, or return the filtered total together with the page. Add a filtered-list assertion for total.

Do not split conjunctions inside string literals.
raw.split(" and ") treats text inside a quoted literal as an operator. For example, name eq 'research and development' becomes two malformed terms and returns HTTP 400.

DashMap::insert is used as a conflict probe, so every 409 path corrupts a uniqueness index. insert replaces the existing value and returns the previous one.

The plugin name uniqueness check is not atomic.
Store is shared through Arc and every handler runs concurrently. This code scans self.plugins for a duplicate name, then inserts under a fresh UUID. Two concurrent POST /oagw/v1/plugins calls with the same name both pass the scan and both insert, so the documented "unique per tenant" invariant breaks and the tenant ends up with two plugins of the same name under different UUIDs.
The scan is also O(n) over every plugin of every tenant on each create.
Add a (tenant_id, name) → Uuid index and claim it with the entry API, which fixes both the race and the scan cost.

Axum WebSocketUpgrade protocols method Sec-WebSocket-Protocol response documentation
💡 Result:
In axum, the WebSocketUpgrade extractor provides methods to handle the Sec-WebSocket-Protocol header for subprotocol negotiation [1][2]. When you call the.protocols method on a WebSocketUpgrade instance, you provide a list of subprotocols the server supports, ordered by preference [1]. If the client requests any of these via the Sec-WebSocket-Protocol header, axum automatically selects the first matching protocol, sets the Sec-WebSocket-Protocol response header in the WebSocket upgrade response, and makes the selected protocol available on the WebSocket connection [1][2][3]. Key methods related to subprotocol handling include: 1..protocols(protocols: I): Configures the server's supported subprotocols [1]. The list should be in decreasing order of preference [2]. 2..requested_protocols(&self): Returns an iterator of the subprotocols requested by the client in the Sec-WebSocket-Protocol header [2][3]. 3..set_selected_protocol(protocol: HeaderValue): Manually sets the chosen subprotocol, overriding any automatic selection from.protocols [1][2]. 4..selected_protocol(&self): Returns the currently selected subprotocol if one has been chosen [1][2]. Note that the Sec-WebSocket-Protocol header is included in the response regardless of whether the connection is HTTP/1.1 or HTTP/2, as mandated by the relevant standards [4][5][6]. If both.protocols and.set_selected_protocol are used, the latter call takes effect [2]. Example usage: async fn handler(ws: WebSocketUpgrade) -> Response { ws.protocols(["graphql-ws", "graphql-transport-ws"]).on_upgrade(|socket| async { //... }) }

site:docs.rs/axum/0.8.9 axum extract ws WebSocketUpgrade set_selected_protocol
💡 Result:
In axum, the WebSocketUpgrade extractor provides the set_selected_protocol method to manually set the chosen WebSocket subprotocol [1][2]. This method takes a HeaderValue as an argument [2]. You can also use the protocols method to configure a list of supported subprotocols [1][2]. When you provide this list, axum automatically negotiates with the client by checking the Sec-WebSocket-Protocol header; if the client offers a supported protocol, axum will automatically include it in the response and select it [1][2]. The protocols should be listed in decreasing order of preference [2]. Example of using the protocols method for automatic negotiation: async fn handler(ws: WebSocketUpgrade) -> Response { ws.protocols(["graphql-ws", "graphql-transport-ws"]).on_upgrade(|socket| async { //... }) } If you need to manually intervene or set the protocol explicitly, you can use set_selected_protocol on the WebSocketUpgrade instance before calling on_upgrade [1][2].

Use the same store for both tenants.
App::new creates a new empty Store. Therefore, this test passes even if management lookups do not enforce tenant scoping.
Construct other with App::with_store(app.store.clone(), ...). This makes the second tenant query the store that contains the first tenant's upstream.
Proposed fix
- let mut other = App::new(
+ let mut other = App::with_store(
+ app.store.clone(),
MockResolver::default_hierarchy(),
context_for(TENANT_OTHER),
test_config(),
);📝 Committable suggestion

In `@gears/system/oagw/oagw/tests/management.rs` around lines 459 - 463, Update
the test’s `other` application construction to use `App::with_store` with
`app.store.clone()` while retaining `MockResolver::default_hierarchy()`,
`context_for(TENANT_OTHER)`, and `test_config()`, so both tenant queries operate
on the same populated store.
