* feat(proxy): parse and display OpenAI chat reasoning effort Parse reasoning effort from openai-compatible /v1/chat/completions requests (top-level reasoning_effort preferred, nested reasoning.effort fallback, top-level wins on conflict) and surface it in the usage log thinking effort column via the openai_reasoning_effort special setting audit with field-source tagging. Also add @lobehub/ui@^5 to satisfy the @lobehub/icons peer dependency. * fix(proxy): normalize chat endpoint and preserve raw effort value Address review feedback: - Compare the normalized endpoint path (trailing-slash tolerant) when deciding whether to record the openai_reasoning_effort audit, matching the endpoint classification used by the guard pipeline. - Preserve the original reasoning effort string (including surrounding whitespace) in the audit value instead of returning the trimmed copy.
) * fix(proxy): destroy Node/Undici body on upstream error to prevent resource leak Fix memory leak where Node/Undici response bodies remained paused with retained sockets and ArrayBuffer backing stores after upstream errors, HTTP/2 resets, or client disconnections. Changes: - Add explicit source stream cancellation in demand-driven pump when primed read fails, ensuring Node-to-Web adapter can release underlying resources - Destroy Node stream explicitly in adapter error path, as source errors bypass Web ReadableStream cancel algorithm - Install bounded async destroy error guard to handle race conditions during teardown - Change raw body error listener from `.on()` to `.once()` in forwarder to prevent long-lived socket retention in HTTP/2 reset and concurrent cancel paths - Add idempotent destroy call in forwarder raw body error handler to clean up resources when Undici auto-destroy races with custom dispatcher teardown - Add test coverage for source read failure cancellation and underlying stream destruction - Fix shell script return values in load test helper * fix(proxy): bound detached stream memory without disabling replay
Symptom: - Remote Compaction v2 requests with previous_response_id skipped the upstream WebSocket path and fell back to HTTP, where they were rejected. Cause: - Raw passthrough request bodies are stored as ArrayBuffer values. - Responses WebSocket body decoding did not support ArrayBuffer, so the upstream WebSocket frame was never sent. Solution: - Decode ArrayBuffer request bodies before constructing the upstream WebSocket frame. - Add regression coverage ensuring Remote Compaction v2 continues over WebSocket.

#1441) * feat(proxy): disable memory-heavy features under high-concurrency mode High-concurrency mode previously only reduced Redis debug snapshots and session observability writes. Memory-heavy coordination features — Replay, stream content gating, hedge-loser billing, client-abort retention, and response diagnostics — continued to run, undermining the CPU and IO savings the mode was designed to provide. ProxySession now exposes policy methods that return false when high-concurrency mode is active, causing the proxy pipeline to skip these features entirely. Forwarding, core billing, and quota enforcement remain enabled. Redis retention TTLs for circuit-breaker state and public-status projections are capped at 24 hours while the mode is active. The settings UI shows a toast warning listing the disabled features. * fix(proxy): keep fake-200 detection active in high-concurrency mode Body inspection for fake-200 HTML responses was gated on shouldParseResponseDiagnostics, which returns false in high-concurrency mode. This inadvertently disabled the core failover guard that triggers provider switching on blocked responses. The diagnostics gate is removed so fake-200 detection remains active regardless of concurrency mode. * fix(proxy): keep request filters active in high-concurrency mode Request filters and the response rectifier were gated on shouldApplyContentTransforms, which returns false in high-concurrency mode. This inadvertently disabled content transformation and response normalization that providers rely on. The gate is removed so filters and the response fixer run regardless of concurrency mode.

会话禁用 Replay 时应释放 owner 租约。
新增的守卫直接 return null，没有调用 declineOwnership()。本函数的其他早退分支（!isReplayEnabled()、并发上限、状态码不符、投递类型不符）都会调用 declineOwnership()，从而释放 Redis owner 租约并清空 session.replayState。
如果某个请求已在 guard 阶段抢到 owner 租约，而随后 shouldUseRequestReplay() 返回 false，租约会保持到 TTL 过期。期间其他相同请求会 attach 到一个永远不会写入内容的 owner 上。
请把该检查移到 owner 判定之后，并复用 declineOwnership()。

处理 updateMessageRequestDetailsDurably 返回 false 的路径。
updateMessageRequestDetailsDurably 可能在未更新任何行时正常返回 false，且不会调用 onCommitted。此时 streamReplayCompletionScheduled 已为 true，异常回退不会执行，清理逻辑也不会释放 clientAbortReplayLease。请在该路径中调用 replaySpool.abort(...)，并在完成后释放租约；仅释放租约会使 spool 保持非终态。

When high-concurrency mode is enabled, this reduces the vendor-type circuit state TTL from 30 days to 24 hours, including states with manualOpen: true. getOrCreateState() in src/lib/vendor-type-circuit-breaker.ts reloads open states on every check and clears the in-memory circuit when the Redis key is missing, so a vendor type that an operator manually disabled is automatically re-enabled after one day and can receive traffic again. Limit the shortened retention to disposable projection data, or exempt manually opened circuit states.

When a provider-specific body filter sets, removes, or text-replaces reasoning_effort or reasoning.effort, this extraction records the filtered value rather than the value sent by the client. The pipeline runs providerRequestFilter before messageContext, and those filters mutate session.request.message in place, while the new audit and UI describe this field as the client's verbatim requested effort. Capture it from the original request before those filters run, or preserve the original value separately.

For a detached /v1/responses stream whose response.completed event exceeds 64 KiB, this cap causes the framer to discard the entire event before compactPayload() can remove its large response.output. Responses terminal events legitimately include the complete output, so a sufficiently long generation loses both its completion marker and terminal usage; the client-abort finalizer then records 499 without billing and rejects an otherwise complete Replay. Parse terminal and usage fields from oversized completion frames with bounded output handling instead of dropping the whole frame.

[HIGH] [LOGIC-BUG] High-concurrency mode silently clears/skips discovery session bindings
Why this is a problem: When high-concurrency mode is active, parseResponseDiagnostics is false, so completionInspection is stubbed to { hasMarker: false, hasProtocolError: false }. Downstream, completionMarkerMissingForBinding (line 1881) then becomes true for every successful discovery stream with create/renew binding intent — requiresCompletionMarkerForBinding is set for all such requests (forwarder.ts:6200) — because "inspection skipped" is conflated with "marker absent". At line 2354 this triggers clearSessionBinding("completion_marker_missing") on every renew and skips binding creation. Sticky-session routing is silently destroyed for all discovery traffic while the mode is enabled, even though the PR and the settings copy describe high-concurrency mode as disabling only memory-heavy features ("Forwarding, core billing, and quota enforcement remain enabled"; binding breakage appears in neither enableHighConcurrencyModeDesc nor highConcurrencyModeWarning). isSessionBindingAllowed() is not gated by this mode, so the path is fully reachable.
Repro: enable High-Concurrency Mode, send a discovery-routed streaming request for a session with an existing binding; the stream completes normally with message_stop, yet the binding is cleared with reason completion_marker_missing and the next request loses its sticky provider.
Suggested fix: never infer "marker missing" from a skipped inspection; run the cheap marker check only for binding-intent requests:
const needsBindingMarker =
meta?.requiresCompletionMarkerForBinding === true && hasDiscoveryBindingIntent;
const completionInspection = parseResponseDiagnostics
? inspectStreamCompletion(allContent, session.originalFormat)
: needsBindingMarker
? {
hasMarker: hasStreamCompletionMarker(allContent, session.originalFormat),
hasProtocolError: false,
}
: { hasMarker: false, hasProtocolError: false };

[MEDIUM] [PERFORMANCE-ISSUE] Per-character framing loop runs on every streaming chunk in default mode
Why this is a problem: clientAbortMeter.observe(value) is invoked unconditionally for every chunk of every streaming response (both observeChunk in the generic stream path and the Gemini passthrough onChunk) whenever high-concurrency mode is off. consume() iterates each character with for...of (code-point iteration, slower than charCodeAt) and builds lines via this.line += character, plus a this.line.length >= this.maxFrameCharacters check per character. The codebase's established incremental SSE framer (src/app/v1/_lib/proxy/stream-gate/sse-frames.ts, SseFrameParser.consume) scans with charCodeAt and only materializes strings at line boundaries, which is substantially cheaper per byte. Since this PR's purpose is stability under high load, putting the slowest variant of this parsing on the hottest path works against that goal.
Suggested fix: adopt the boundary-scan pattern for line extraction, keeping the frame-drop/overflow bookkeeping unchanged:
private consume(text: string): void {
let start = 0;
for (let index = 0; index < text.length; index += 1) {
const code = text.charCodeAt(index);
if (code !== 10 && code !== 13) continue;
this.appendCharacters(text.slice(start, index)); // slice at boundaries only
this.handleLineBreak(code === 13 && index === text.length - 1);
start = index + 1;
}
this.appendCharacters(text.slice(start));
}with appendCharacters enforcing maxFrameCharacters on the accumulated length instead of per character.

[MEDIUM] [TEST-EDGE-CASE] New Gemini buffer-limit throw branch has no test
Why this is a problem: CLAUDE.md Rule 2 states "All new features must have unit test coverage of at least 80%". This new guard throws inside TransformStream.transform, which errors the client-facing stream for any single Gemini line above 1 MiB — a behavior change versus the previous unbounded buffering, and the whole point of this guard is the OOM bound this release ships. The only added test covers the accept path ("accepts a large Gemini chunk composed of complete short lines"); the throw path is untested, so a regression here (wrong boundary, error surfacing from the wrong stream, or a pump that never settles) would go unnoticed.
Suggested fix: add a companion unit test in tests/unit/proxy/response-handler-stream-terminal.test.ts:
it("errors the client stream when a single Gemini line exceeds the transform buffer limit", async () => {
const { session } = await createSession({});
session.setProvider({ ...createProvider(), providerType: "gemini" });
session.originalFormat = "claude";
const body = `data: ${JSON.stringify({
candidates: [{ content: { parts: [{ text: "x".repeat(1024 * 1024 + 1) }] } }] },
})}\n\n`;
const returned = await ProxyResponseHandler.dispatch(session, sseResponse(body));
await expect(returned.text()).rejects.toThrow(
"Gemini stream line exceeded transform buffer limit"
);
});(adjust the final assertion to how the harness surfaces transform errors if .text() wraps them)

Code Review Summary
This release PR ships the #1430 off-heap OOM fix set (bounded detached-stream budgeting, metering-only client-abort drains, explicit Node stream teardown), the high-concurrency mode feature gates, and three smaller fixes (Responses WS ArrayBuffer/SSE, OpenAI reasoning-effort audit). The detached-stream lease lifecycle, evidence compaction, and env validation are well tested overall; one release-blocking interaction between the high-concurrency gates and discovery session binding slipped through, plus a hot-path CPU concern and one untested error branch.
PR Size: XL
- Lines changed: 3054 (2944 additions, 110 deletions)
- Files changed: 55
Split suggestions: As a dev-to-main release aggregation of six already-reviewed PRs, this PR is not splittable in the usual sense. Before promoting to main, consider landing a follow-up on dev that fixes the binding interaction below and folding it into this release, since high-concurrency mode is a shipped, user-toggleable setting in v0.9.4. For future release PRs, bundling the feature PR (#1441) that introduces a new user-facing toggle together with the memory-fix PRs (#1439/#1440) is what made cross-feature interactions like this one hard to catch.

StubbingcompletionInspection.hasMarkertofalsemakescompletionMarkerMissingForBindingtrue for every successful create/renew discovery stream (requiresCompletionMarkerForBindingis set for all of them inforwarder.ts:6200), so renew paths callclearSessionBinding("completion_marker_missing")and create paths skip binding.

Severity High / release-blocking; detailed inline comment with fix posted.
High Priority Issues (Should Fix)
- [PERFORMANCE-ISSUE, confidence 80] Per-character framing on the streaming hot path (
src/app/v1/_lib/proxy/client-abort-metering.ts:285). The meter runs on every chunk of every streaming response in default mode; itsfor...of+ per-character+=line builder is markedly slower than the repo's own boundary-slicingSseFrameParserpattern. Inline comment with a concrete rewrite posted. - [TEST-EDGE-CASE, confidence 80] Gemini transform buffer-limit throw branch untested (
