score > (best_quality, best_priority), so the first candidate wins a tie. Theindexvalue is stored in the tuple but is never compared, so it has no effect.
ControlPlaneServiceImpl::resolve_proxy_targetcalls this function once per upstream, closest tenant first, so today the mixed-chain case does not occur.

PluginContext::request_id_from_headersreads only the fixedx-request-idheader, and it rejects a blank or over-long value. This code instead propagates the inbound value of the configured header. Ifheadernames another header, three identifiers can diverge: the request relays the inbound custom-header value,transform_responsestampsctx.request_id(), and the audit line recordsctx.request_id(). The comment at lines 63-65 states that the response carries the identifier the request was stamped with, so the invariant breaks.

Inline comments:
In `@gears/system/oagw/docs/schemas/route.v1.schema.json`:
- Around line 69-70: Restore plugin-reference validation in all four listed
schema locations: route.v1.schema.json lines 69-70 and 76-78, and
upstream.v1.schema.json lines 125 and 131-133. Update the bare reference and
plugin_ref definitions to accept only documented built-in GTS identifiers or
tenant-plugin UUIDs, while preserving their existing descriptions and schema
structure.
In `@gears/system/oagw/oagw/src/api/rest/routes.rs`:
- Around line 36-42: Align the proxy contract with the actual routing in
PROXY_DESCRIPTION and proxy_operations: either register a method-agnostic route
so CONNECT, TRACE, and extension methods reach proxy::relay or
proxy::relay_root, or restrict the documented methods to GET, POST, PUT, PATCH,
DELETE, HEAD, and OPTIONS. If retaining the restricted contract, add an
integration test covering CONNECT.
In `@gears/system/oagw/oagw/src/domain/merge.rs`:
- Around line 351-366: Update union_cors so the merged CorsConfig never retains
allow_credentials when allowed_origins contains the wildcard "*"; compute the
deduplicated origin set first, then set credentials false for wildcard unions
while preserving the existing OR behavior for explicit origins.
In `@gears/system/oagw/oagw/src/domain/ratelimit.rs`:
- Around line 65-69: Update the sustained-limit selection to choose one
candidate by the lowest refill_per_second() value, preserving that candidate’s
matching rate and window instead of selecting fields independently. Apply this
in the sustained-rate calculation around sustained_rate and sustained_window,
and add cross-window tests covering enforced ancestor and descendant limits.
In `@gears/system/oagw/oagw/src/infra/controlplane/mod.rs`:
- Around line 1069-1074: Update list_plugins so that when plugin_type is None it
enforces Read permission for every plugin type that may be returned, rather than
defaulting to gts::TRANSFORM_PLUGIN_TYPE_ID; preserve the existing single-type
permission check when a filter is supplied and ensure unauthorized plugin types
are not returned.
In `@gears/system/oagw/oagw/src/infra/plugin/oauth2_cc_auth.rs`:
- Around line 259-266: The OAuth2ClientCredAuthPlugin::fetch flow must validate
tenant-controlled issuer_url and token_endpoint hosts against the gear’s
private-address/SSRF protections before issuer discovery and token requests.
Reuse the equivalent DataPlaneServiceImpl::validate_endpoint behavior or shared
validation helper for both configured and discovered endpoints, rejecting unsafe
endpoints before calling toolkit_auth::oauth2::fetch_token.
In `@gears/system/oagw/oagw/src/infra/storage/mod.rs`:
- Around line 142-167: Update replace to keep alias_index consistent when an
upstream alias changes, removing the old mapping and inserting the new one, then
update find_by_alias to use the maintained index for alias lookups; preserve
tenant scoping and existing validation behavior.
- Around line 96-104: Normalize upstream aliases at the repository write
boundary in InMemoryStore::put_upstream and save_upstream before insert or
replace and duplicate checks, using the same canonicalization as control-plane
writes. Ensure stored aliases and comparisons are consistently normalized while
preserving case-insensitive find_by_alias behavior.
In `@gears/system/oagw/oagw/tests/proxy_sse_tests.rs`:
- Around line 97-107: Update the TestUpstream stream in the relevant proxy SSE
test to fail or terminate prematurely after emitting the initial event, then
assert the client-visible 502 response and cf.oagw.stream.aborted.v1 error
contract. If the test is intended to remain a healthy-stream case, instead
rename it so it no longer implies StreamAborted coverage.

Restore plugin-reference validation in both published schemas.
The descriptions require either a built-in GTS identifier or a tenant-plugin UUID. The new type: "string" fields accept arbitrary values such as "not-a-plugin".

🔒 Security & Privacy | 🟠 Major | ⚡ Quick win
union_cors can produce a wildcard origin together with allow_credentials.
validate_config in domain/cors.rs rejects allow_credentials: true combined with "*" at create time. union_cors bypasses that invariant: it unions origins and ORs allow_credentials. Two enforce ancestors, one with allowed_origins: ["*"] and no credentials, and one with explicit origins and allow_credentials: true, merge into {"*", …} plus credentials. The proxy response path echoes the request origin for a wildcard configuration, so a credentialed CORS policy would then apply to every origin.

Compare sustained throughput, not the raw rate field.
Line 65 selects the smallest numeric rate. Line 66 then selects the shortest window independently. This can loosen an enforced limit. For example, 100/minute combined with 10/second produces 10/second, although 100/minute is stricter.
Select the configuration with the lowest refill_per_second() value and retain its matching rate/window pair. Add cross-window tests for enforced ancestor and descendant limits.

list_plugins checks the wrong permission when no type filter is supplied.
With plugin_type == None the check uses gts::TRANSFORM_PLUGIN_TYPE_ID, but the store then returns plugins of every type, including auth plugins. A caller that holds read on transform plugins receives auth and guard plugins, and Plugin serializes source_code and config_schema. This bypasses the per-type permission model of DESIGN.md §3.2.
Check read on each plugin type when the filter is absent, or filter the result to the types the caller may read.

Add SSRF host validation to OAuth2 requests
OAuth2ClientCredAuthPlugin::fetch passes tenant-controlled token_endpoint or issuer_url to toolkit_auth::oauth2::fetch_token. The OAuth2 client validates URL syntax and transport scheme, but it does not apply the gear's private-address checks. The existing DataPlaneServiceImpl::validate_endpoint guard protects only proxy upstream selection. Apply equivalent host validation to issuer discovery and the discovered or configured token endpoint. Otherwise, a tenant can make the gateway connect to internal addresses.

Enforce alias normalization at the repository boundary.
The control-plane write paths normalize aliases, but public InMemoryStore::put_upstream and save_upstream accept raw aliases. insert and replace compare them with case-sensitive ==, while find_by_alias uses eq_ignore_ascii_case. A direct caller can therefore store both Vendor and vendor; lookups return the first stored entry. Normalize aliases in repository writes or enforce a normalized alias type.

Update alias_index in replace, or remove the index.
insert (lines 105-106) adds an alias_index entry and delete (lines 177-187) removes it, but replace never updates it. After an alias change, the index maps the old alias to the upstream id and holds no entry for the new alias. No code in this file reads alias_index; find_by_alias scans state.upstreams. The staleness is therefore latent today, but the module doc at lines 5-7 states that the index serves the hot lookup, so the next reader of the index would resolve a stale alias.
Choose one direction: maintain the index in replace and use it in find_by_alias, which also removes the linear scan from the alias lookup, or delete the index and correct the module doc.

This test does not abort a stream, so it does not cover StreamAborted.
The upstream returns stream::iter(vec![Ok(...)]). That stream yields one complete chunk and then ends normally. No abort occurs. The assertions only check 200 and that the body contains event: token, so the test passes for a healthy relay and asserts nothing about a gateway problem.
Mid-stream abort is a documented contract (502 cf.oagw.stream.aborted.v1). As written, a regression in abort handling still passes. Make the upstream stream fail after the first chunk, or close the connection before the declared body completes, and then assert the observed client-visible outcome. If the intent is only to pin the happy path, rename the test.
