fix(responses): bundle L2 — Responses and streaming fixes (#5706, #5683, #5714, #5704, #5707) - #5738
Conversation
Claude Code sends metadata.user_id as a ~186-char JSON string. It was copied verbatim into the Responses 'user' field, which Azure OpenAI and other OpenAI-compatible backends cap at 64 chars, so every Claude Code request routed to Azure failed with 400 "Invalid 'user': string too long". Keep short ids as-is and send the SHA-256 hex digest (already computed for prompt_cache_key) when the id exceeds 64 chars. Fixes #5705 Co-authored-by: Giulio Leone <giulioleone097@gmail.com>

An explicit upstreamWebsocket: false now routes streaming canonical ChatGPT turns over HTTP/SSE before sending. This gives operators a supported escape from intermittent post-send WebSocket closes without replaying ambiguous turns. The default remains WebSocket and native WS controls are unavailable when HTTP is selected. Verified: focused Responses/provider suites, typecheck, structure check, privacy scan, docs build. Changed-area suite rerun pending. Co-authored-by: kosta <kosta963@gmail.com>

Anthropic streams may include any number of ping events. The adapter only turned SSE comments into heartbeats, so a long silent thinking phase that pinged was cut off at stallTimeoutSec with upstream_stall_timeout. Named and data-only ping records now yield the same heartbeat. Refs #5707
…roviders The row coerced an unset value to false. After the canonical ChatGPT opt-out, unset means upstream WebSocket and false means HTTP/SSE, so a save built from the row could turn WebSocket off. The row now omits the key when it is unset. Co-authored-by: kosta <kosta963@gmail.com>
…-out The reference row, its seven translations, and the provider type and schema comments still said the canonical ChatGPT transport ignores upstreamWebsocket. It now selects HTTP/SSE when set to false. The locale rows were also behind the English row on the first-party-only restriction; they are retranslated from it.

When plaintext V2 is enabled and an upstream returns successful headers with a missing or unrecognized content type but never produces its first body chunk, this reader.read() waits indefinitely. It runs before executePassthroughResponse installs guardDirectPassthroughBodyInactivity, so the configured stallTimeoutSec never fires and the request and upstream-host lease remain held until the client aborts. Race these prefix reads against the upstream signal and the same inactivity deadline, returning the existing stall failure representation on expiry.

…utSec The carried probe read the first chunk of an unlabeled body with no deadline, before the passthrough stall guard is attached. An upstream that sent headers but no body held the request and its host lease until the client gave up, and a failed read escaped the classifier. Each probe read now races a per-read inactivity window and one total budget, both stallTimeoutSec, plus the client abort signal. Timeout, abort, and read errors cancel the reader and return the existing unsupported-content-type 502. Docs now scope the recovery to missing or unrecognized non-JSON content types.

The affected conversation also completed with HTTP 200 after an initial local headerless-SSE correction, before replacing that workaround with this bounded upstream implementation. No additional provider replay was performed after that replacement; the backport results above are local handler checks. Recording the confirmation here rather than opening a duplicate PR. The installed stable version at diagnosis was 2.64.0; this merged fix was not yet included in that package. |

Summary
Lane L2 bundle: five Responses and streaming fixes, landed together. Four carry open contributor PRs onto current
dev, and one fixes issue #5707 directly.metadata.user_id.src/claude/inbound.tscopied it into the Responsesuserfield, which OpenAI and Azure cap at 64 characters, so every Claude Code request to an Azure model returned 400. Ids of 64 characters or fewer still pass through unchanged. Longer ids are replaced by their SHA-256 hex digest, the same digest that already producesprompt_cache_key, so cache keys don't change. The follow-up commit pins the exact hash value and the 64/65-character boundary.Content-Type, or withtext/plain. WhenplaintextV2AgentMessageswas on, the passthrough answered those with a synthetic 502 instead of restoring the aliased tool names. It now reads at most the first 4 KiB, confirms a Responses SSE event, and replays the original bytes through the existing restoration path. Unknown bodies still fail closed. The carried commit is unchanged. On top of it, one follow-up commit (b91aede49f) bounds the probe. Before, the probe'sreader.read()had no deadline and ran before the passthrough stall guard is attached, so an upstream that sent headers but no body held the request and its host lease open indefinitely. Before the carry, the same response got an immediate 502. Maintainer review on fix(responses): restore plaintext V2 calls from verified unlabeled SSE #5683, the Codex review bot, and CodeRabbit all flagged this. Each probe read now races a per-read inactivity window and one total budget, both set bystallTimeoutSec, plus the client abort signal. On timeout, abort, or read error, the probe cancels the reader and returns the existing "unsupported content type" 502. The docs now scope the recovery to missing or unrecognized non-JSON content types. The lane packet said "rebase only" for fix(responses): restore plaintext V2 calls from verified unlabeled SSE #5683, so if the coordinator prefers the carry as it was, reverting that one commit restores it.openai-chatadapter omits it (models outsidepreserveReasoningContentModels). Long threads could therefore get a localcontext_length_exceededrefusal for history that is never sent. Direct and combo admission now use the adapter's own preservation rule. The direct and combo tests assert that the 120,000-character thinking string is absent from the dropped wire body and present when reasoning is preserved. A follow-up commit fixes the English and Korean architecture sentence that review flagged: it now says the false refusal is prevented by excluding thinking that is never sent, and the preserved-model rule is a separate sentence.providers.openai.upstreamWebsocket: falsesends its streaming turns over HTTP/SSE. Omitting it keeps the WebSocket default, and provider management rejectstrueon that row. Withfalse, native mid-turn steering and injection are unavailable. Follow-ups from review:GET /api/providersreportedupstreamWebsocketas=== true, so an unset canonical value came back asfalse. Saving that row would have switched WebSocket off. The row now reports the configured value and omits the key when it is unset, the same wayupstreamHttpVersionalready works.src/types/provider.ts, andsrc/config/schema/leaf-validators.tsstill said the canonical transport ignores this flag. They now describe the new behavior. The locale rows had also fallen behind the English row on the first-party-only restriction, so they were retranslated from it.pingevents count as upstream liveness (fixes Anthropic adapter drops ping events, so long pre-output thinking on Opus 5.5 hits upstream_stall_timeout at 300 s #5707). Anthropic streams "may also include any number ofpingevents" (streaming docs).src/adapters/anthropic.tsturned SSE comments into heartbeats but dropped pings. A long thinking phase that only pinged was therefore cut off atstallTimeoutSec(300 s) withupstream_stall_timeout. Namedevent: pingrecords and data-only{"type":"ping"}records now yield the same heartbeat, which resets the bridge stall watchdog. Timeouts are unchanged, no synthetic keepalive is added, and the "slow thinking vs hung upstream" redesign the issue also suggests is not attempted.Carries #5706
