Goals / Non-Goals + +**Goals** +- The chat-completions path item appears in the spec whenever a local resolver **or** a remote backend is configured (local / remote / hybrid). +- Every `WithUpstreamRouter` mounted path appears in the spec as a minimal, honest `POST` proxy item. +- De-dupe: a real item (chat, openapi-spec, swagger, or a `DescribableGroup` path) always wins over the minimal proxy item at the same path. +- Follow the existing special-cased-path mechanism — no new abstraction. + +**Non-Goals** +- Inferring real request/response schemas for generic router paths (the router proxies arbitrary shapes — the minimal item is deliberately loose). +- Documenting all HTTP methods the router's `r.Any` accepts (POST only — see §3). +- Surfacing runtime routing data (model→pool table, adapters) in the static spec. +- Changing how `DescribableGroup` or `chatCompletionsPathItem` themselves work. + +## 3.

No schema change — only the enabling condition widens. The remote backend is OpenAI-shaped (passthrough or adapted), so the existing schema remains accurate. + +### 3.2 Upstream router paths (minimal proxy item) +Each `WithUpstreamRouter` mounted path (from `WithRouterPaths`, default `["/v1/chat/completions"]`) gets a minimal but honest `POST` item: + +- **Method:** `POST` only. The router uses `r.Any`, but documenting all seven methods with freeform bodies is misleading noise; `POST` matches the inference convention and the default path. +- **Tag:** `proxy` (distinct from the real `inference` chat item, so consumers can tell a generic proxy path from the typed chat endpoint). +- **Request body:** generic `object` (`additionalProperties: true`), `required: true`, with the description: *"Selector-routed proxy. The request body must carry the selector field (default `model`); the concrete request/response schema depends on the target upstream/model."* +- **Responses:** `200` with `application/json` (generic `object`) **and** `text/event-stream` (the router streams); `404` (`no_upstream_for_key`); `503` (`upstream_unavailable`, with a `Retry-After` response header) — matching the router's real envelopes. +- **Security:** same `isPublicPathForList` treatment as the other path items (no forced-public; honours configured public paths). + +### 3.3 De-dup rule +The router-path loop runs **after** the chat/openapi-spec special items and the `DescribableGroup` loop. For each router path, normalise it and skip if the `paths` map already has that key.
