📝 WalkthroughWalkthroughAdds the OAGW gateway with tenant-scoped control-plane APIs, REST management routes, HTTP/SSE/WebSocket proxying, plugin execution, credentials, CORS, rate limiting, typed errors, TLS transport, configuration, and extensive unit and integration tests. ChangesOAGW gateway
Priority: ➖ Normal Estimated code review effort: 5 (Critical) | ~120 minutes Severity of issue fixed: Medium Merge Risk: 🟠 High · up to This introduces a new API gateway whose current behavior has several serious gaps: configuration owned by a parent tenant can be changed or deleted by a child tenant, routes that use path parameters never match so those proxied calls fail, request-size limits can be bypassed by chunked uploads, per-IP rate limiting can be evaded with a spoofed forwarding header, and WebSocket upgrades can drop the first upstream frame. These should be resolved before merge. 🚥 Pre-merge checks | ✅ 3 | ❌ 2❌ Failed checks (1 warning, 1 inconclusive)

108-127: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick winParameter segments do not count toward specificity, so a shorter route can win.
literalscounts only literal segments. For the request/v1/abcwith routes/v1and/v1/{id}, both scoreliterals = 1. The priorities tie at the default 0, so the tie-break at Line 58 prefers the lexicographically smaller path,/v1. The less specific route wins andparamsreturns empty. The module header states that the most specific route wins, so the score contradicts the contract. The catch-all branch at Line 114 also incrementsliteralsfor a non-literal segment, which makes{*rest}score above a plain{id}.Return the matched template segment count as the primary score and keep the literal count as the tie-break.
Line 117 is also unreachable, because
path_segmentsfilters empty segments.🐛 Proposed fix

🎯 Functional Correctness | 🔴 Critical | ⚡ Quick win
Parameterized routes never match through InMemoryRouteRepo.
path_starts_with compares the request path against the route path literally, and list_matching at Line 240 uses it to pre-filter candidates. A route path that holds a {param} segment can never pass that filter. For the route /v1/entities/{gts_id} and the request /v1/entities/abc, path == prefix is false and path.strip_prefix("/v1/entities/{gts_id}") is None, so the route is dropped before match_route can capture the parameter. The caller then receives RouteNotFound for a route the control plane accepted.
The comment also inverts the arguments: { would have to appear in the request path, not in the route template.
routing.rs::parameter_segments_capture_values does not catch this, because FakeRepo::list_matching ignores the path and returns every enabled route.
Compare only the literal segments that precede the first {.

only still-valid issues, skip the rest with a brief reason, keep changes
minimal, and validate.
In `@gears/system/oagw/oagw/src/infra/memory_repo.rs` around lines 293 - 296,
Update InMemoryRouteRepo::path_starts_with, used by list_matching, to compare
only the literal route segments before the first `{` parameter marker, rather
than requiring the full parameterized template to prefix-match the request path.
Preserve the existing segment-boundary checks so `/v1` does not match `/v10`,
and add coverage for `/v1/entities/{gts_id}` matching `/v1/entities/abc`.
