Diego Rodrigues de Sa e Souza c5707e65de fix(sse): require Responses-shaped body before native OpenAI-compatible passthrough (#12129) (#13278)
Merged as part of the 39-PR owner batch of 2026-09-11, validated as a unit.

Boarded into one consolidated worktree cut from `release/v3.8.51` with the other 38 — zero conflicts between them.

- ESLint over every changed file: no errors (the only finding was one suppression entry the batch emptied, pruned on #13243)
- `typecheck:core` clean; `check:dashboard-typecheck` OK (206 pre-existing, within baseline); `check:changelog-integrity` OK
- complexity 2821 / baseline 3218 and cognitive-complexity 1272 / baseline 1437 — both under baseline
- 256 assertions green: 246 under node:test and 10 under vitest, which is where `tests/unit/**/*.test.tsx` actually runs
- `check-file-size`: `chatCore.ts` rebaselined 6144 → 6146 for #13278 and #13276, annotated and landed on #13243

⚠️ base-red inherited: #12732 — the provider count (356 in the docs vs the 358 the modules define) and `open-sse/utils/stream.ts` at 3115 > frozen 3098 both reproduce on the pure tip with zero contribution from this batch.

// Regression test for issue #12129: an internal context-handoff summary request (built in
// Chat Completions shape -- `messages`, no `input`) is dispatched through the SAME
// handleSingleModel closure that carries the ORIGINAL client request's endpoint.
// When that original endpoint matched `/responses` and the resolved handoff-model
// provider is an openai-compatible-* connection configured with apiType "responses",
// the pipeline used to decide the body was already native-Responses-shaped and skip
// chat->responses translation entirely (`_nativeOpenAICompatibleResponsesPassthrough`),
// so the upstream received `messages` on `/v1/responses` and rejected it with zero input.
//
// Fix: `shouldUseNativeOpenAICompatibleResponsesPassthrough` now requires the body to
// actually look Responses-shaped (`input` present, `messages` absent) before allowing
// the passthrough fast path, so an internally-synthesized chat-shaped body is routed
// through the normal chat->responses translation layer instead.
