Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to This change adds Kimi K3 and Moonshot Responses compatibility, but a few bounded issues remain: annotated fenced tool inputs may not normalize correctly, model normalization can mutate request data, and the report contains inaccurate and environment-specific details. Address these before broad use of the new compatibility path. Sequence Diagram(s)sequenceDiagram

리뷰 · 우선순위 58 / 80지금 이 PR(#3952)은 한 묶음에 세 가지를 넣었습니다. 첫째, Chat 모델이 왜 중요한가. K3/Chat 모델이 freeform 도구를 잘못 감싸면 V8이 문법 오류로 죽고, 도구 한 번 부른 뒤 멈추기도 합니다. 그 부분은 실제 사용자 통증이 있습니다. 다만 moonshot을 Responses로 통째로 옮기는 일은 freeform 완화와 성격이 다릅니다. Responses 전환은 스트림 이벤트, 도구 호출, reasoning 회수, 기존 Chat 스키마 정규화(#2677 계열)까지 한꺼번에 바꿉니다. 이 PR은 아직 draft이고 리뷰 준비 체크리스트도 비어 있습니다. 경로/심볼 - 경로/심볼 - 경로/심볼 - 경로/심볼 - 경로/심볼 - 경로/심볼 - 경로/심볼 - import 메인테이너의 판단이 필요한 지점

Update the report to match the final implementation.
The report names tests/adapters/openai/k3-compat.test.ts, but this change uses tests/adapters/openai/openai-chat-compat.test.ts. It also reports a 262,144-token context window and a 262,144-token output limit. The metadata entry defines contextWindow: 1048576 and maxTokens: 131072.
Also applies to: 34-34, 42-42, 55-55

Do not mutate parsed._rawBody during model normalization.
When parsed.options?.tierDecision is absent, applyTierDecisionToResponsesBody returns the original _rawBody. Line 2375 then changes that caller-owned object. A retry, alternate adapter path, or frozen request body can observe the wrong model or throw. Replace the assignment with an immutable body rewrite.
Proposed fix
if (provider.modelSuffixBracketStrip && isPlainObject(outBody) && typeof (outBody as { model?: unknown }).model === "string") {
- (outBody as { model: string }).model = stripBracketedModelSuffix((outBody as { model: string }).model);
+ outBody = {
+ ...outBody,
+ model: stripBracketedModelSuffix(outBody.model),
+ };

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Accept complete Markdown info strings.
OUTER_MARKDOWN_CODE_FENCE accepts only one token after the opening fence. A valid wrapper such as ```javascript filename=tool.js\n...\n``` does not match, so unwrapFreeformToolInput returns the fence markers unchanged. Downstream apply_patch detection can then receive the fenced text instead of the patch body.
Match the complete opening info line and add a regression test for an annotated fence.
