9-12: 🩺 Stability & Availability | 🔵 TrivialPlan an entry cap or a TTL before an
ip-scoped limit is exposed to untrusted clients.The registry never evicts. An
ip-scoped limit therefore creates one permanent entry per distinct source address. A client pool that spans an IPv6 /64 grows the map without bound for the life of the process, so the instance eventually exhausts memory.The module records this as the accepted release behaviour, so no change is required here. Track a bounded entry count or an idle TTL per shard, and add a gauge for total entry count so the growth is observable before it becomes an outage.

Inline comments:
In `@gears/system/oagw/docs/DECOMPOSITION.md`:
- Line 77: Update ExecutionPlan::auth_phase flow so both dispatch and
upgrade_flow build outbound requests from the final prepared context after
plugin phases: convert prepared.query to the outbound query representation and
pass prepared.headers instead of matched.outbound_query and the pre-plugin
outbound_headers. Keep HTTP scheme handling and credential-policy behavior
unchanged.
In `@gears/system/oagw/docs/features/gear-wiring.md`:
- Line 264: Define the disabled-upstream wire contract consistently across the
authoritative mapping table and the gear-wiring, hierarchical-resolution, and
proxy contracts: map the disabled disposition to an existing OagwError variant
and GTS type that returns HTTP 503, or explicitly revise the closed 22-row rule
to add that mapping. Ensure all referenced documentation uses the same contract.
- Line 260: Update inst-em-08 to apply application/problem+json only to
gateway-classified errors; in the upstream passthrough branch, preserve the
upstream status, body, content type, and all other headers, adding only
X-OAGW-Error-Source: upstream.
In `@gears/system/oagw/docs/features/hierarchical-config.md`:
- Line 240: Reconcile the documented merge order between the route-tier
statement near the hierarchical layering description and the `Upstream < Route <
Tenant` rule. Choose one ordering and apply it consistently to
`EffectiveConfig`, `inst-me-09`, downstream plugin execution, and the acceptance
criteria, including ordered plugin bindings.
In `@gears/system/oagw/docs/features/management-api.md`:
- Line 232: Update the create/replace handling to generate a server UUID only
when creating a new upstream. For replacement requests, preserve the existing
path identifier as the immutable stored and returned id, including all
references and indexes.
- Line 274: Clarify the route uniqueness invariant for disabled routes, then
align storage enforcement, management API conflict responses, and acceptance
tests with that rule. Use the route creation/update logic and the existing
conflict-status handling symbol to ensure duplicate path, priority, and method
combinations are treated consistently without changing unrelated behavior.
In `@gears/system/oagw/docs/features/observability.md`:
- Line 263: Add retry_after_seconds to the closed audit-record schema
definitions referenced by the observability document, including the contracts
around the WARN record, so the computed Retry-After delay required for
cpt-cf-oagw-flow-rate-limit-check can be represented consistently. Update all
relevant schema declarations rather than removing the existing delay
requirement.
- Around line 269-271: Update Telemetry::audit so it hands records to
StdoutAuditSink::write_line through a non-blocking mechanism, ensuring stdout
locking, writing, and flushing cannot delay request completion; preserve
best-effort record suppression and independent request status, headers, and body
behavior.
In `@gears/system/oagw/docs/features/plugin-chain.md`:
- Around line 252-253: Update the documented credential-injection and
scheme-policy behavior for API-key and OAuth2 upstreams so credential-bearing
requests cannot be sent over HTTP: require HTTPS for authenticated requests, or
explicitly skip credential injection when allow_http_upstream permits an HTTP
endpoint.
In `@gears/system/oagw/docs/features/rate-limiting.md`:
- Around line 156-157: Update the RateLimiter registry described in the
rate-limiting feature so it enforces a configurable capacity bound and evicts
idle scope-key entries, including entries across sharded HashMap instances.
Preserve active entries during eviction to prevent churn from resetting their
limits, and document the resulting bounded-memory behavior while retaining the
existing request lookup semantics.
In `@gears/system/oagw/oagw/src/api/rest/proxy_handler.rs`:
- Around line 189-190: Update the authenticated proxy response flow around
response.headers_mut() and upstream_passthrough to set Cache-Control to no-store
before forwarding the response, ensuring upstream cache directives cannot enable
reuse across application identities.
In `@gears/system/oagw/oagw/src/api/rest/route_shell.rs`:
- Line 198: Update route_shell::mount after merging proxy_shell to add an OAGW
fallback for unmatched paths, routing them through the existing
error_mapping_middleware so unknown /oagw/v1/... requests return the
RouteNotFound problem+json response with X-OAGW-Error-Source: gateway instead of
Axum’s default empty 404.
In `@gears/system/oagw/oagw/src/domain/streaming.rs`:
- Around line 581-618: Update StreamSessionState::transition to hold a single
state mutex guard across both transition validation and the state assignment;
avoid locking separately for reading current and writing to. Preserve the
existing valid-transition matrix and error behavior while making the
check-and-update atomic.
In `@gears/system/oagw/oagw/src/infra/plugin/token_cache.rs`:
- Around line 112-119: Update hash_config to make configuration entries
structurally unambiguous before hashing: include the total pair count and hash
each key as a distinct length-delimited component alongside its value,
preserving deterministic BTreeMap ordering and the existing hexadecimal output
format.
In `@gears/system/oagw/oagw/src/infra/plugin/transform.rs`:
- Around line 149-152: In gears/system/oagw/oagw/src/infra/plugin/transform.rs

gears/system/oagw/oagw/src/infra/plugin/plan.rs lines 813-816, remove the
#[ignore] attribute from the pinning test once both transform drivers preserve
the no-binding-config-left-behind invariant.
In `@gears/system/oagw/oagw/src/infra/proxy/limiter.rs`:
- Around line 359-361: Update the limiter flow around the entries lookup and
before decide to refresh an existing LimiterEntry’s capacity and refill_rate
from the effective limit on every request, not only during
LimiterEntry::cold_to_active insertion. When the rate changes, preserve the
current token balance but clamp tokens to the new capacity so reported limits
and refill behavior stay consistent.
In `@gears/system/oagw/oagw/src/infra/proxy/streaming.rs`:
- Around line 583-584: Update the teardown logic in pump around
client_write.shutdown and upstream_write.shutdown to bound each shutdown future
with the existing timeout mechanism, ensuring a stalled TLS close_notify/flush
cannot block stream cleanup or failure recording. Preserve best-effort shutdown
behavior by continuing after either timeout.
- Around line 244-251: Update the streamed-content detection around
streamed_content_type to inspect only the first semicolon-delimited Content-Type
token, trimming and case-insensitively comparing that media type with
SSE_CONTENT_TYPE; do not use any() over later parameters. Preserve the existing
size-hint fallback and boolean behavior.
In `@gears/system/oagw/oagw/src/infra/storage/route.rs`:
- Around line 264-268: Update set_enabled to handle the route disappearing after
its initial read: replace the routes.get_mut(...).expect("present") assertion
with a not-found error return when the entry is absent, while preserving the
existing mutation path when it is present.
In `@gears/system/oagw/oagw/src/infra/storage/upstream.rs`:
- Around line 126-131: Update the replacement logic in UpstreamRepository,
RouteRepository, and PluginRepository to retain the removed Stored entry’s seq
when replacing an existing resource. Call inner.next_seq() only when inserting a
new resource, while preserving the existing insertion-order sorting behavior
used by each list method.

| 1. **Route registration base path** — all oagw routes are registered at `/oagw/v1/...` WITHOUT a leading `/api` (task mandate; gear-relative paths are also how sibling gears register routes — e.g. account-management mounts `/account-management/v1/...`). The paths written in PRD/DESIGN as `/api/oagw/v1/...` are absolute paths behind an operator-facing gateway and are not the paths this deployment serves. FEATURE docs and their API sections use `/oagw/v1/...`; the `/api/oagw/v1/...` form is documented as the operator-gateway-prefixed alias. | ||
| 2. **`http` is a legal endpoint scheme** — the management API must accept `"scheme": "http"` for upstream endpoints (`gears.oagw.config.allow_http_upstream: true` in the graded config lifts the `cpt-cf-oagw-constraint-https-only` default posture). Two distinct concerns stay apart: (a) which schemes the `Upstream.server.endpoints[].scheme` field accepts — `http`, `https`, `wss`, `grpc`, `wt`; (b) whether a plaintext connection is actually established — governed only by `allow_http_upstream` (default `false`). This extends the scheme enum of `schemas/upstream.v1.schema.json` (`https`, `wss`, `wt`, `grpc`) with `http`; `wt` remains valid configuration but is not proxied (deferral 7). |

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Forward the final plugin context to both outbound paths.
ExecutionPlan::auth_phase copies injected header and query credentials into prepared, and request transforms mutate that context. target is built from matched.outbound_query before the plugin phases, while dispatch and upgrade_flow use the pre-plugin outbound_headers. Configured authentication and request transformations are therefore omitted. Convert the final prepared.query to the outbound query representation and pass prepared.headers to both paths. Keep this functional fix separate from HTTP credential policy; this stale-context path does not establish plugin-credential disclosure.

Do not generate a new UUID during replacement.
Line 232 says that both create and replace server-generate the UUID. A PUT /.../{id} addresses an existing resource, and Line 91 defines that identity as immutable. Generate the UUID only on create. Preserve the path identifier during replacement so references and indexes remain valid.

Refresh bucket parameters when the effective rate changes.
LimiterEntry::cold_to_active initializes capacity and refill_rate only when the key is inserted. resolve_scope_key excludes the rate, so an existing entry is reused. A same-window change from 10/s to 1000/s can therefore keep refilling at 10/s while X-RateLimit-Limit reports 1000. Update the existing bucket from the effective limit before decide, and clamp tokens to the new capacity.

Match text/event-stream only as the media type.
The bridge represents exact-size responses as OutboundBody::Streaming while preserving their exact size hint. With Content-Type: application/json; x=text/event-stream, .any() classifies the response as streamed. handover then moves the session to Streaming and attaches the journal failure recorder instead of completing the session without that recorder. The response bytes and headers remain unchanged, but the lifecycle and failure behavior differ.
Match only the first token:

Bound the two teardown shutdowns.
BoxDuplex can contain the TLS stream created by the configured hyper-rustls upgrade path. Its shutdown() sends close_notify and flushes pending TLS data before it shuts down the underlying stream.

set_enabled can panic when the route is deleted concurrently.
Lines 250-259 take a read lock, clone the route, and release the lock. Line 264 takes the write lock afterwards. Another thread can call delete for the same (tenant_id, id) in that window. Line 268 then calls expect("present") on a missing entry and panics on the request thread. Return not-found instead of asserting presence.

let mut inner = self.inner.write();
if let Some(field) = Self::determinism_conflict(&inner, tenant_id, &candidate) {
return Err(already_exists(field, "route match key"));

Preserve the stored sequence on replacement in all three stores.
UpstreamRepository::list, RouteRepository::list, and PluginRepository::list sort by Stored.seq, and their contracts require insertion order. Each replacement assigns inner.next_seq(), so the replaced resource moves to the end and can change paginated results. Reuse the removed entry’s seq; call inner.next_seq() only for new inserts.
