state that provider routing or account selection does not bypass the upstream

🟡 Changes recommended
The new hint/docs currently risk misleading users due to overly broad gating and Pool-vs-Direct wording ambiguity that should be corrected before approval.
Once you've addressed the issues Copilot identified, you can request another Copilot review.
Pull request overview
This PR improves operator/user guidance around ChatGPT-family latency when routing through the canonical openai (Codex login) provider, by documenting the public ChatGPT endpoint queue behavior and surfacing the same explanation in ocx doctor, along with a clarification about requested vs granted service_tier.
Changes:
- Add a new
ocx doctorhint explaining public ChatGPT endpoint queue latency and native app-channel limitations when the canonicalopenaiResponses provider is configured. - Add test coverage ensuring the hint appears only when applicable and avoids claiming a fixed delay.
- Document the same behavior and the requested-vs-granted
service_tierdistinction in the Codex integration guide.

Streaming turns already ride the ChatGPT websocket transport (the same responses_websockets lane Codex CLI defaults to); the remaining gap is the public-endpoint queue itself, in both Pool and Direct modes. service_tier=priority is a request preference: this backend can echo service_tier \"default\" even on turns it scheduled as priority (#2558), so the echoed response tier in request logs stays an observation with confirmation \"assumed\" and cannot confirm or deny the granted tier.

Qualify the WebSocket transport claim.
Line 1019 says all streaming turns use the ChatGPT WebSocket transport. Eligible requests can use responses_websockets, but unsupported WebSocket settings fall back to HTTP/SSE. The current doctor output and documentation give users an incorrect transport diagnosis.

As per path instructions, docs-site/** must stay synchronized with actual CLI/API behavior, and the adapter reference requires that unsupported WebSocket settings fall back to HTTP/SSE.

Second fix round on this branch (head 3bd66da), narrowing user-facing copy that the helper cannot support. The previous wording said streaming turns "already ride the ChatGPT websocket transport" and that "the remaining gap is the public-endpoint queue itself, not the transport". Current source contradicts both halves as an unconditional claim: codexWsUpstreamFetch falls back to SSE over HTTP on an unprepared request, an unsupported Bun runtime, an oversized create frame, or a proxy route that cannot carry the socket (src/server/responses/ws-upstream.ts), and every request first waits on local provider pacing (src/server/responses/fetch-helpers.ts waitForPacing). chatgptPublicEndpointHint classifies configuration and measures none of that, so it must not attribute an observed delay to the upstream queue. The hint and the guide now say eligible streaming turns dial the websocket lane and fall back to SSE, that local pacing can hold a request before dispatch, and that upstream queueing is one possible contributor to be compared against actual transport, pacing, network, and provider observations. Both Pool and Direct still use the public endpoint, and the non-authoritative service_tier wording is unchanged. The test locks the hedge so the copy cannot silently harden again. No runtime logic changed; the canonical-provider classifier and its tests are untouched. Verification: remote CI re-run on this exact head (34322687958 Cross-platform CI, 34322687915 React Doctor); local typecheck/tests NOT RUN (local, user restriction). |
