Summary

  • Adds muse-spark-1.3-contributor to OpenCode Go registry defaults:
    • modelWireDefaults: routes to openai-responses (prevents 500 error on chat completions).
    • modelContextWindows: sets 1_048_576 (1M) context window, matching its 1.1 and 1.2 siblings (prevents 128k fallback).
    • modelInputModalities: sets ["text", "image"] for native multimodal support (prevents client-side image blocking).
  • Generalizes stripMuseSparkUnsupportedWebSearchFields in src/adapters/openai-responses.ts from an exact 1.2 string check to a slug.startsWith("muse-spark") family check, ensuring any Muse Spark model on Responses has unsupported search_content_types stripped from plain web_search tools (prevents 400 invalid_request_error).
  • Enables family-prefix fallback for muse-spark in providerModelWireDefault and modelRecordValue so future sibling versions inherit appropriate Responses wire routing, 1M context, and multimodal capabilities.
  • Expands regression tests across muse-spark-web-search-compat.test.ts, opencode-go-muse-context.test.ts, and opencode-go-muse-vision.test.ts.

Review Change Stack

📝 Walkthrough

Walkthrough

The PR registers Muse Spark 1.3 for opencode-go with Responses routing, a 1M context window, and image support. It extends Muse Spark family matching for wire, adapter, reasoning, and web-search handling. Tests cover both Muse Spark 1.2 and 1.3.

Changes

Muse Spark model support

Layer / File(s) Summary
Model registration and capability coverage
src/providers/registry.ts, tests/opencode-go-muse-context.test.ts, tests/opencode-go-muse-vision.test.ts
muse-spark-1.3-contributor uses openai-responses, has a 1,048,576-token context window, and supports text and image input. Context and vision tests now cover both Muse Spark models.
Model resolution and adapter lookup
src/providers/registry.ts, src/reasoning-effort.ts, src/server/adapter-resolve.ts
Wire resolution and modelRecordValue now match namespaced Muse Spark IDs by family prefix. Adapter resolution uses modelRecordValue for per-model overrides.
Web-search compatibility
src/adapters/openai-responses.ts, tests/muse-spark-web-search-compat.test.ts
Web-search sanitization removes search_content_types for Muse Spark model IDs while preserving the tool type and search_context_size. The test covers Muse Spark 1.3.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 113b0

The change adds family-based routing for Muse Spark models, but the current prefix match could also classify similarly named models and send them through the wrong request format. The PR is mergeable with explicit owner awareness, provided the family check is made delimiter-aware and covered by a near-match regression test.

이 PR은 OpenCode Go에서 새로 보이는 muse-spark-1.3-contributor를 지금 dev에 이미 있는 Muse Spark 1.2 Contributor 취급과 같은 줄에 올리려는 수정입니다. 지금 HEAD(af314b0a)의 src/providers/registry.ts opencode-go 항목에는 muse-spark-1.2-contributormodelWireDefaultsopenai-responses로 박혀 있고, modelContextWindows는 1M(1_048_576), modelInputModalitiestext+image입니다. 웹검색 쪽은 src/adapters/openai-responses.tsstripMuseSparkUnsupportedWebSearchFields가 모델 아이디가 정확히 muse-spark-1.2-contributor일 때만 web_search에서 search_content_types를 떼어 냅니다. 1.3이 Zen Go에 올라오면 Chat로 가면 500, Responses로 가야 하는데 레지스트리 기본값이 없어서 Chat로 떨어지고, 컨텍스트는 128k로 떨어지고, 이미지는 클라이언트가 막아서 요청도 못 나가는 상태가 됩니다. 그래서 이 PR은 (1) 1.3을 wire/context/modality 맵에 직접 넣고, (2) stripMuseSparkUnsupportedWebSearchFieldsmuse-spark 접두사 가족으로 넓히고, (3) providerModelWireDefault와 공용 modelRecordValuemuse-spark 가족 폴백을 넣어 앞으로 나올 형제도 같이 타게 하려는 구성입니다. 테스트도 tests/muse-spark-web-search-compat.test.ts, tests/opencode-go-muse-context.test.ts, tests/opencode-go-muse-vision.test.ts에 1.3을 끼워 넣었습니다.

다만 같은 목표를 더 넓게, 그리고 실측 근거와 함께 다루는 열린 PR이 이미 있습니다. #3315(guhcostan, 약 20분 먼저 열림)는 1.3을 Responses로 보내는 것 외에 reasoning effort 사다리(nonexhigh, maxxhigh), 도구 이름 64자 제한, 순환 $ref 스키마 드롭까지 넣었고, 2026-09-02 Zen Go 프로브 기록을 Decision Log에 남겼습니다. 그 PR은 컨텍스트 1M 행은 의도적으로 안 넣었습니다(형제 문서가 아니라 프로브로 확인한 뒤 넣겠다는 뜻). 또 지금 dev의 Decision Log와 tests/muse-spark-web-search-compat.test.ts의 “exact-model allowlist, not a family rule” 문장은 형제를 이름으로 끌지 말라고 못 박아 둔 상태입니다. 이 PR의 가족 폴백은 그 약속과 충돌합니다.

그래서 점수는 중간보다 낮게 잡았습니다. 1.3을 살리는 방향 자체는 맞고, 로컬로 돌렸다는 tsc/관련 테스트도 좁은 범위에서는 초록으로 보입니다. 하지만 (a) 공용 헬퍼에 Muse 전용 폴백을 넣는 설계가 dev 불변식과 어긋나고, (b) #3315가 같은 버그를 더 완전한 가드와 실측으로 이미 다루고 있어서, 이 PR을 그대로 머지하면 중복·충돌·불완전한 1.3 수정이 됩니다. 우선순위 44는 “관심은 있지만 지금 형태로는 닫거나 #3315 쪽으로 흡수” 구간입니다.

라인 src/reasoning-effort.ts modelRecordValue - 공용 조회 함수에 muse-spark 전용 가족 폴백이 들어갔습니다. 이 함수는 reasoning effort·verbosity·summary delivery·(이 PR로) modelAdapters까지 씁니다. 레코드에 있는 첫 번째 muse-spark* 키 값을 아무 muse-spark* 아이디에나 돌려줍니다. 1.2와 1.3이 effort 맵처럼 서로 다른 값을 가져야 할 때 잘못된 값을 조용히 물려줍니다.
라인 src/providers/registry.ts providerModelWireDefault - slug.startsWith("muse-spark")이면 opencode-go에서 무조건 openai-responses입니다. Decision Log와 기존 테스트가 지키던 exact-model allowlist를 가족 규칙으로 바꿉니다. 맵에 없는 muse-spark-1.2(contributor 아님)도 Responses로 끌려갈 수 있습니다.
경로 src/providers/registry.ts modelContextWindows["muse-spark-1.3-contributor"] - 1M을 형제(1.2/1.1) 문서 닮음으로 선언했습니다. #3315는 같은 모델을 프로브한 뒤 컨텍스트 행은 일부러 비워 두었습니다. 프로브 없이 1M을 넣으면 카탈로그가 실제보다 큰 창을 광고할 수 있습니다.
경로 전체 대비 #3315 - 이 PR만 머지하면 reasoning maxxhigh 맵, 64자 도구 이름 드롭, 순환 $ref 드롭이 없어서 Codex MCP 세션에서 1.3이 여전히 400 날 수 있습니다. Wire/비전/웹검색 일부만 고치고 실제 Codex 턴은 깨진 채로 남을 수 있습니다.
라인 src/server/adapter-resolve.ts - modelAdapters 조회를 modelRecordValue로 바꿨습니다. 위 가족 폴백과 합쳐지면 사용자가 1.2에만 넣은 override가 1.3에도 조용히 적용될 수 있습니다.

메인테이너의 판단이 필요한 지점

  • #3315#3316 중 어느 쪽을 기준으로 1.3을 들일지 (권장: 프로브·effort·도구 가드가 있는 #3315).
  • 1.3 컨텍스트를 지금 1M으로 넣을지, 프로브 후 follow-up으로 미룰지.
  • Muse 가족 폴백을 공용 modelRecordValue/providerModelWireDefault에 둘지, 아니면 Decision Log대로 exact id만 레지스트리 맵에 추가할지 (후자가 지금 dev 불변식과 맞음).

너의 추천
#3316은 supersede로 닫고 #3315를 기준으로 머지하세요. 닫을 때 Superseded by #3315와 함께 “가족 폴백·미검증 1M은 dev exact-allowlist와 충돌, effort/도구 가드 없음”을 한 줄로 남기면 됩니다. 1M 컨텍스트가 필요하면 #3315 머지 후 프로브 근거 PR을 따로 받는 편이 안전합니다. 이 PR만 살려야 한다면 가족 폴백을 걷어내고 exact muse-spark-1.3-contributor 행만 남긴 뒤 #3315의 effort·도구 가드를 흡수해야 합니다.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Use a delimiter-aware Muse Spark family match.

slug.startsWith("muse-spark") also matches unrelated slugs such as muse-sparkle. The resolver in src/server/adapter-resolve.ts Lines 21-49 consumes this result, so such a model can switch from openai-chat to openai-responses and receive the wrong request shape.

Match muse-spark exactly or require the muse-spark- delimiter. Add regression cases for a namespaced model, a future sibling, and a near-miss slug.

Proposed fix
-    if (id === "opencode-go" && slug.startsWith("muse-spark")) {
+    if (id === "opencode-go" && (slug === "muse-spark" || slug.startsWith("muse-spark-"))) {

As per path instructions, “A behavior change in src/ should come with a focused regression test near the existing tests for that subsystem.”

Thanks for the review!

The motivation behind the family prefix matching (muse-spark*) is that every Muse model on OpenCode Zen/Go exclusively answers on the Responses wire, accepts multimodal image inputs, and rejects search_content_types on plain web_search.

Without family prefix matching, every minor version bump (like 1.2 -> 1.3 -> 1.4) completely breaks the model for users (500 errors on Chat, client-side image blocks, and 400 errors on web search) until a new PR is written, reviewed, and merged.

If scoping the fallback in the shared modelRecordValue helper is too broad for the repo's design philosophy, we can scope the muse-spark* family check strictly to opencode-go wire defaults and adapter sanitization, while keeping explicit registry entries for the known versions.

Also note that #3315 is currently missing both modelInputModalities (causing Codex to block image attachments client-side with "This model does not support image inputs") and modelContextWindows (capping context to 128k instead of 1M), which this PR includes and verifies with live probes and test coverage.
