Merge Risk: 🟠 High · up to This change introduces a new outbound API gateway that proxies tenant traffic. As written, it does not enforce the configured protection against requests to internal network addresses, can forward upstream credentials over unencrypted connections, buffers entire request bodies before enforcing the size limit, and accumulates per-client state that is never released in a long-running process. Several control-plane endpoints also accept invalid or ambiguous configuration. These should be resolved before merge. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 inconclusive)

resolved-address validation before both HTTP and WebSocket outbound connection
paths rather than only in DataPlane::check_transport. Reject loopback,
link-local, RFC1918, and other private addresses unless explicitly covered by
allowed_cidrs; retain enabled: false only as an explicit E2E override.

- Around line 119-125: Update enforce_alias and enforce_alias_update to validate
normalized explicit aliases with is_valid_alias before returning them or passing
them to persistence. Preserve the existing requirement that explicit aliases are
non-empty, and return the established validation error for invalid values so

In `@gears/system/oagw/oagw/src/domain/breaker.rs`:
- Around line 90-108: Update the breaker state machine around is_open and probe
so expiry enters a distinct half-open state, admits only one in-flight probe,
and keeps concurrent callers open until that probe reports success or failure;
preserve the existing reopen behavior on probe failure and close behavior on

logic. Ensure enforced ancestor limits cannot be weakened when their per-second
rate is lower after normalization.
In `@gears/system/oagw/oagw/src/domain/ratelimit.rs`:
- Around line 106-109: Update the bucket management in the rate-limit check flow
around the CounterKey entry and Bucket::last timestamp to evict stale entries
older than a fixed multiple of the configured window, using periodic or bounded
opportunistic cleanup while preserving active buckets and existing rate-limit
behavior.
- Around line 35-39: Update the RateScope::Route arm to key counters only by
route, removing subject from its tuple while preserving the tenant and route
identifiers. If per-subject behavior is intentional instead, revise the Route
scope documentation in model.rs to describe that contract.
In `@gears/system/oagw/oagw/src/domain/store.rs`:
- Around line 95-101: Update read-only accessors to use the non-inserting
tenant_tables() lookup instead of tenant(), including get_upstream,
get_upstream_by_alias, list_upstreams, get_route, list_routes, get_plugin, and
list_plugins. Preserve tenant() for insert paths so missing tenants are not
allocated during reads.
- Around line 355-366: Update same_match to compare HTTP methods as a
normalized, case-insensitive set rather than an order-sensitive sequence, while
preserving path and priority checks. Make the (None, None) gRPC branch also
require matching priority. Add a test covering equivalent method lists in
different orders and asserting the second route conflicts.
In `@gears/system/oagw/oagw/src/gear.rs`:
- Around line 86-96: The DataPlane construction in gear initialization must
propagate OagwConfig.ssrf_policy through DpConfig, and route_request must
enforce it against resolved upstream and websocket target addresses before send
or open_websocket. Reject loopback, link-local, and private addresses unless
explicitly allowlisted, and keep redirect targets subject to the same validation
if redirect handling is enabled.
In `@gears/system/oagw/oagw/src/infra/dp/mod.rs`:
- Around line 87-98: Update the HTTP client initialization branch around
cfg.allow_http_upstream so a TLS-only fallback also sets the effective
allow_http_upstream policy to false, ensuring check_transport and allows_http
reject plaintext; alternatively, fail initialization when the requested
plaintext-capable transport cannot be built.
- Around line 198-199: Update check_transport so plaintext upstream requests
cannot forward credentials: when the target uses HTTP, reject the request if
authentication may add an Authorization header, even when allow_http_upstream is
enabled, or remove sensitive headers before send forwards the request. Preserve
secure HTTPS and explicitly permitted non-credential HTTP traffic, using the
surrounding authentication and send flow to apply the smallest safe change.
In `@gears/system/oagw/oagw/src/infra/dp/ws.rs`:
- Around line 187-193: Update relay to implement an inactivity timeout rather
than wrapping the entire copy_bidirectional session in one timeout. Track byte
progress for both client-to-upstream and upstream-to-client transfers, refresh
the idle deadline whenever either direction transfers bytes, and close only
after no traffic occurs for idle. Preserve the existing AsyncRead, AsyncWrite,
and Unpin bounds and relay behavior.
In `@gears/system/oagw/oagw/src/infra/plugin/apikey.rs`:
- Around line 62-67: Update the query-string construction in the QUERY branch to
percent-encode both the query parameter name and the resolved key value before
interpolation, using an existing workspace URL-encoding helper. Preserve the
current handling of existing query parameters while ensuring reserved characters
and spaces remain part of their intended parameter values.
In `@gears/system/oagw/oagw/src/infra/plugin/oauth2.rs`:
- Around line 163-174: The OAuth2 client currently permits non-TLS requests. In
OAuth2ClientCredAuthPlugin::new, validate token_endpoint and issuer_url to
require HTTPS, configure http_config with TransportSecurity::TlsOnly before
constructing OAuthClientConfig, and ensure this setting also applies to token
endpoints obtained through OIDC discovery.
- Around line 163-174: Update the OAuth2 URL validation around token_endpoint,
issuer_url, discovery, and token exchange to reject resolved loopback, private,
and link-local destinations before any request is made. Apply the same
destination validation to every redirect target, including same-origin
redirects, while preserving existing URL parsing and validation errors.

Minor comments:
In `@gears/system/oagw/oagw/src/api/dto.rs`:
- Around line 14-21: Add #[serde(deny_unknown_fields)] to the request DTO
definitions generated or declared for UpstreamDto and RouteDto, ensuring unknown
top-level request fields are rejected while preserving the existing response
deserialization and default behavior.
In `@gears/system/oagw/oagw/src/api/handlers.rs`:
- Around line 63-76: Update retain_alias_filter to return a validation result
instead of silently returning or doing nothing for unsupported filter
expressions, including non-alias fields and malformed or compound syntax. In
list_upstreams, propagate the validation error from retain_alias_filter so
invalid $filter requests use the existing error_400 response while valid alias
filters continue narrowing the results.
- Around line 302-309: Update plugin_kind to return a Result and reject values
that do not identify exactly one supported plugin kind, rather than defaulting
to guard or accepting ambiguous matches. Propagate this validation in
create_plugin by handling plugin_kind(&dto.plugin_type)? before constructing the
plugin ID, so unknown plugin_type values use the existing error_400 response.
In `@gears/system/oagw/oagw/src/api/routes.rs`:
- Around line 87-89: Register the 409 conflict response on the
oagw.update_upstream operation by adding error_409 alongside its existing
error_400, error_404, and error_500 responses. Use the existing conflict
response registration pattern from the POST operation and leave the other
response mappings unchanged.
In `@gears/system/oagw/oagw/src/domain/ratelimit.rs`:
- Around line 100-102: Update RateLimiter::check to replace the u64-to-f64
conversions for capacity and cost and the f64-to-u64 conversions in the
refill/token calculations with lint-compliant conversions, preserving the
existing clamping and rate-limit behavior; use narrow justified allowances only
if safe conversions are not available.
In `@gears/system/oagw/oagw/src/domain/store.rs`:
- Around line 286-291: Make delete_plugin return distinct errors for an unknown
plugin and a referenced plugin, using a dedicated not-found variant for the
empty-match path and an in-use variant for reference failures. Update the delete
handler to map the not-found variant to OagwError::route_not_found and the
in-use variant to OagwError::plugin_in_use, preserving the declared 404 and 409
responses.
In `@gears/system/oagw/oagw/src/infra/plugin/request_id.rs`:
- Around line 40-42: Update the response handling around REQUEST_ID_HEADER so it
inserts the actual generated request ID instead of an empty string when no
upstream request-ID header exists. Ensure the request ID is propagated into this
response phase, or injected before on_response executes, while preserving the
existing header behavior.

Nitpick comments:
In `@gears/system/oagw/oagw/src/api/handlers.rs`:
- Around line 35-40: Remove the duplicate resolve_upstream function and update
create_route to call the existing find_upstream resolver instead, preserving the
current upstream lookup behavior.
In `@gears/system/oagw/oagw/src/domain/errors.rs`:
- Around line 48-50: Add concise Rust doc comments to the public constants
ERROR_SOURCE_GATEWAY and ERROR_SOURCE_UPSTREAM, and to every public variant of
ErrorKind. Keep the documentation focused on each symbol’s meaning and do not
alter behavior.
- Around line 294-313: Update ErrorKind::status_value to derive its result from
the canonical ErrorKind::status mapping instead of duplicating the
variant-to-status match, preserving the existing u16 return value and behavior
for every error kind.
In `@gears/system/oagw/oagw/src/domain/mod.rs`:
- Around line 172-184: Update the "auth" arm in the plugin-kind validation match
to reject identifiers where model::builtin_plugins::is_catalog_only(id) is true,
using the same validation error behavior and plugins.items field as the existing
"guard" rejection. Preserve acceptance of non-catalog-only auth plugins.
In `@gears/system/oagw/oagw/src/domain/model.rs`:
- Around line 196-202: Update Target::authority to determine the default port
from the target’s secure scheme: omit the port only for HTTPS/443 or HTTP/80,
and include it for mismatched combinations such as secure on 80 or insecure on
443. Preserve the existing host formatting for non-standard ports.
In `@gears/system/oagw/oagw/src/domain/store.rs`:
- Around line 320-339: Move mark_unlinked_if_orphaned calls from the successful
delete_plugin path to the unbinding paths in put_upstream and put_route, after
plugin bindings are removed, while the plugin record still exists. Add the
missing garbage-collection routine that reads unlinked_since and removes entries
according to the behavior described by its existing documentation.
In `@gears/system/oagw/oagw/src/infra/dp/request.rs`:
- Around line 53-61: Update upgrade_head to validate each header name and value
before writing them to the wire, returning OagwError when either cannot be
represented; preserve the documented error contract and existing successful
output behavior.
In `@gears/system/oagw/oagw/src/infra/dp/ws.rs`:
- Around line 263-267: Update bytes_of to read and decode header.value directly,
removing pointer arithmetic and buffer slicing; preserve its invalid UTF-8
fallback behavior. Adjust the parse_head call site to use the simplified
bytes_of signature.

Reject oversized request bodies before buffering. The OAGW routes have no DefaultBodyLimit or RequestBodyLimitLayer. route_request calls body.collect() before validate_body checks state.dp.max_body_size(), so oversized requests can consume memory up to their full size before rejection. Add a transport-layer limit configured from the same maximum.

Implement round-robin selection for explicit-alias pools.
When X-OAGW-Target-Host is absent, select_target returns endpoints[0]. This bypasses PoolCursor::next, so traffic does not round-robin as documented. Add a shared PoolCursor to OagwState and pass it to select_target, or remove the round-robin documentation and cursor.

Half-open does not limit the probe to a single request, and probe mutates state.
The comment states "allow a single probe through". The branch sets opened_at = None and clears failures. The breaker then returns to the fully closed state. Every subsequent request reaches the failing endpoint until failure_threshold new failures accumulate. With the default thresholds, a dead upstream receives 5 requests per 30-second cycle instead of 1.
is_open at Line 142 calls probe, so any observational call consumes the transition. A metrics or logging caller silently closes the breaker.
Track a distinct half-open state so that only one in-flight probe is admitted, and keep the breaker open for other callers until that probe reports success or failure. Add a separate non-mutating accessor for is_open.

This branch builds a TLS-only client but keeps cfg.allow_http_upstream set to true. Consequently, check_transport and allows_http still report that plaintext is supported. Plaintext requests then fail later in the HTTP client.
Set the effective flag to false, or fail initialization when the requested transport cannot be created.

🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy lift
relay applies a total session deadline, not an idle timeout.
tokio::time::timeout wraps the whole copy_bidirectional future. The future only completes when the splice ends. The timer therefore fires after idle has elapsed since the start of the session, even when both directions carry traffic continuously. The doc comment and the parameter name state idle behaviour.
Any WebSocket session that stays active longer than idle is closed while it is in use. Reset the deadline on each byte transferred instead.
🐛 Sketch of an idle-based deadline
- let _ = tokio::time::timeout(idle, tokio::io::copy_bidirectional(client, upstream)).await;
+ // Copy each direction with its own deadline that is reset whenever
+ // bytes move, so only a quiet session is torn down.
+ let copy = tokio::io::copy_bidirectional(client, upstream);
+ tokio::pin!(copy);
+ let deadline = tokio::time::sleep(idle);
+ tokio::pin!(deadline);
+ loop {
+ tokio::select! {
+ _ = &mut copy => break,
+ () = &mut deadline => break,
+ }
+ }copy_bidirectional reports no per-chunk progress, so an accurate idle timeout needs a counting wrapper around both halves, or two separate copy tasks that refresh a shared deadline. Confirm which shape you want before you implement it.

Percent-encode the key before you append it to the query string.
The resolved key is interpolated raw. A key that contains +, &, #, =, or a space produces a different value upstream or a different parameter. Base64 key material commonly contains + and /, and + decodes as a space on the upstream side. The result is a silent authentication failure that is hard to diagnose.
Encode both the parameter name and the key value.

update_route skips the duplicate match-rule check, so a PUT can create an ambiguous route pair.
create_route rejects a duplicate through insert_route, which calls same_match under the write lock (gears/system/oagw/oagw/src/domain/store.rs Lines 216-225). update_route calls put_route, which inserts unconditionally (store.rs Lines 231-235). No uniqueness check runs.
Trigger:
POST /oagw/v1/routeswith path/v1, methodGET, priority0.POST /oagw/v1/routeswith path/v2, methodGET, priority0.PUT /oagw/v1/routes/{id-of-second}with path/v1, methodGET, priority0.
Step 3 succeeds. The same upstream now holds two routes with an identical match rule. route_order (store.rs Line 68) gives both the same sort key except for route.id, so the effective route is decided arbitrarily.
Add the same conflict check to the update path. Exclude the route being replaced from the comparison. Note that update_route does not register error_409 in gears/system/oagw/oagw/src/api/routes.rs (Lines 160-162), so add it there too.

same_match compares method sequences, not method sets, so the duplicate-route check is bypassable.
Line 358 uses x.methods.iter().eq(y.methods.iter()). That comparison is order sensitive and case sensitive. The documented invariant on insert_route (Line 212) and the conflict message (Line 222) both state "method set".
A caller can create two routes with the same path and priority and the same logical method set:
POST /oagw/v1/routeswithmethods: ["GET", "POST"].POST /oagw/v1/routeswithmethods: ["POST", "GET"].
The second request is not rejected with 409. Two overlapping routes then coexist. route_order (Line 68) gives both the same (Reverse(path_len), Reverse(priority)) key, so the winner is decided by the route.id tiebreak. The effective route becomes arbitrary from the caller's view. Differing method case, such as "get" against "GET", evades the check the same way.
The (None, None) arm has a separate inconsistency: it ignores priority, so two gRPC routes for the same service and method but different priorities are rejected as duplicates, while the HTTP arm allows the equivalent case.
🐛 Proposed fix: normalize methods to a set
/// `true` when two routes match on path, priority and method set.
fn same_match(a: &Route, b: &Route) -> bool {
match (&a.matcher.http, &b.matcher.http) {
(Some(x), Some(y)) => {
- x.path == y.path && a.priority == b.priority && x.methods.iter().eq(y.methods.iter())
+ x.path == y.path && a.priority == b.priority && method_set(x) == method_set(y)
}
(None, None) => {
- a.matcher.grpc.as_ref().map(|g| (&g.service, &g.method))
- == b.matcher.grpc.as_ref().map(|g| (&g.service, &g.method))
+ a.priority == b.priority
+ && a.matcher.grpc.as_ref().map(|g| (&g.service, &g.method))
+ == b.matcher.grpc.as_ref().map(|g| (&g.service, &g.method))
}

same_match to compare HTTP methods as a normalized, case-insensitive set rather
than an order-sensitive sequence, while preserving path and priority checks.
Make the (None, None) gRPC branch also require matching priority. Add a test
covering equivalent method lists in different orders and asserting the second
