fix(catalog): apply custom-model capabilities before combo derivation

[Ingwannu]

Summary

• make combo derivation see explicit custom-model context, input modalities, reasoning ladder, and tool mode
• keep those overrides private to the combo member map instead of widening the provider-native model
• preserve the existing final custom-row materializer and routed-slug deduplication order
• add the 组合开启多模态，但模型不支持image #4689 reproduction and document the catalog contract

Fixes #4689.

Root cause

gatherRoutedModelsUncached() built memberByKey and derived every combo before it materialized config.customModels. The Models inventory therefore showed the explicit custom row (text, image in the reporter screenshots), while combo derivation resolved the earlier provider/discovery row and could intersect the same target as text-only.

This was not evidence that every Alibaba or DeepSeek route should be globally marked image-capable. The authority is the operator's exact custom-model declaration, scoped to that provider/model row.

Decision Log

• Purpose: make one custom model and every combo that targets it publish the same explicit capabilities.
• Constraint: provider-native capability metadata and unrelated models must not be widened.
• Alternatives: move the full custom-row materializer ahead of combo derivation, or overlay only explicit custom fields onto the private combo member map.
• Choice: use the scoped overlay.
• Why: moving the full materializer would reorder public catalog construction, dedupe, and warning behavior; the private map is already the sole input to combo intersection.
• Impact: explicit context, modality, reasoning, and tool-mode fields constrain combo derivation; inherited fields still come from the same provider row.

Validation

Exact head: ea23a2132

All commands used temporary HOME, OPENCODEX_HOME, CODEX_HOME, and PASEO_HOME, with credential environment variables removed.

• bun test tests/codex-integration/codex-catalog.test.ts --timeout 30000 — 340 pass, 0 fail
• bun test tests/gui/combo-workspace-data.test.ts --timeout 30000 — 42 pass, 0 fail
• bun run typecheck — pass
• bun run structure:check — pass
• bun run privacy:scan — pass
• git diff --check — pass

The five protected local runtime files were not modified.

@lidge-jun The reporter's follow-up screenshots narrowed this to a custom-row ordering bug rather than an upstream capability guess. Please review the scoped overlay and exact-head CI before merge; I will not self-approve or self-merge it.

이 PR은 이슈 #4689를 고친다. 리포터가 커스텀 모델 행에는 text, image가 보이는데, 그 모델을 타깃으로 넣은 콤보 행은 text만 나오는 불일치였다. 지금 dev HEAD는 5dfea7235(#4686, 패키지 2.57.0)이고, 카탈로그 모으기 본체는 src/codex/catalog/routed-gather.ts의 gatherRoutedModelsUncached다. 여기에는 이미 콤보용 비공개 맵 memberByKey가 있다. 콤보 멤버는 resolveComboCatalogMember가 이 맵을 보고, deriveComboCatalogModel이 멤버 inputModalities의 교집합으로 콤보 행을 만든다. 그런데 지금 dev에서는 config.customModels를 나중에야 공개 카탈로그에 붙인다(같은 파일 약 482행 이후). 그래서 Models 목록의 커스텀 행은 운영자가 적은 모달리티를 보여 주는데, 그 앞 단계에서 이미 끝난 콤보 유도는 예전 provider/discovery 행만 보고 text로 깎일 수 있다. 리포터 후속 댓글과 Ingwannu 진단이 그 순서 버그를 가리킨다. 알리바바/DeepSeek를 전역으로 image라고 찍는 문제가 아니다. 권한은 그 커스텀 행의 선언에만 있다.

고치는 방법은 좁다. memberByKey를 만든 직후, 네이티브 OpenAI synthetic 주입과 콤보 루프 전에, config.customModels를 한 바퀴 돌며 같은 provider/modelId 키에만 명시 필드를 덮어쓴다. 덮는 값은 contextWindow, inputModalities, reasoningEfforts, codexToolMode뿐이고, 없으면 기존 행(또는 최소 stub)을 상속한다. catalogKind는 CODEX_CUSTOM_MODEL_CATALOG_KIND로 표시한다. 공개 커스텀 행 조립·라우티드 슬러그 중복 제거·경고 순서는 그대로 둔다. 전체 materializer를 앞으로 옮기면 공개 카탈로그 생산 순서가 바뀌므로, 비공개 콤보 입력 맵만 맞추는 선택이 Decision Log와 맞다. structure/catalog.md에도 그 계약을 한 단락 적어 두었다.

테스트는 tests/codex-integration/codex-catalog.test.ts에 #4689 재현을 넣었다. provider seed에는 모달리티가 없고, 커스텀 행만 text, image와 context/reasoning/tool-mode를 준 뒤, 이미지 가능 모델과 failover 콤보를 만든다. 기대값은 커스텀 행과 combo/image_failover가 같은 교집합을 보여 주는 것이다. 로컬 exact-head ea23a2132에서 catalog/combo 테스트·typecheck·structure·privacy가 통과했다고 적혀 있다. 호스티드 CI는 아직 pending이다. 보호 런타임 파일은 건드리지 않았다. types.ts/config.ts 스플릿이나 고드파일 모놀리스 경로를 건드리지 않으므로 close-don't-rebase 대상이 아니다. 2.56.0 promote #4694와는 별 레인이라, dev에 들어가도 promote 트리에 자동으로 실리지 않는다.

src/codex/catalog/routed-gather.ts memberByKey 직후 오버레이 - 커스텀 명시 필드만 콤보 입력 맵에 반영. provider-native 공개 행을 넓히지 않는다. 의도에 맞다.
src/codex/catalog/routed-gather.ts 오버레이 위치 - 네이티브 OpenAI synthetic·콤보 루프보다 앞. openai 커스텀 키가 있으면 이후 if (!memberByKey.has)가 덮지 않아 커스텀이 이긴다.
경로 gatherRoutedModelsUncached 후반 custom materializer - 공개 행 조립은 그대로 뒤에 남는다. 맵 오버레이와 공개 조립이 두 번 읽히므로, 나중에 필드가 늘어나면 두 곳을 같이 맞춰야 한다.
tests/codex-integration/codex-catalog.test.ts #4689 테스트 - 성공 경로(커스텀 image → 콤보 image)만 있다. 커스텀에 모달리티가 없을 때 예전처럼 text로 남는 음성 회귀는 없다.
호스티드 CI - exact-head 게이트가 아직 pending. 머지 전 초록 확인이 필요하다.

메인테이너의 판단이 필요한 지점

• #4689를 이 PR 머지와 함께 닫을지(Fixes 링크는 이미 있음).
• 오버레이에 displayName·maxInputTokens 같은 공개 materializer 전용 필드까지 맞출지, 지금처럼 교집합에 쓰는 능력 필드만 둘지.
• 2.56.0 promote #4694에 체리픽이 필요한지, 아니면 2.57.0 dev 레인에만 둘지.
• 커스텀 행이 provider seed에 아예 없을 때 stub(provider/id/owned_by만)으로 콤보에 넣는 동작을 제품 계약으로 확정할지.

너의 추천
호스티드 CI가 exact-head ea23a2132에서 초록이면 dev에 머지한다. #4689는 Fixes로 같이 닫힌다. Alibaba/DeepSeek 전역 시드를 image로 바꾸지 말 것 — 이번 고침의 핵심은 커스텀 선언을 콤보 유도에만 보이게 하는 것이다. 가능하면 커스텀 모달리티 없음 → 콤보 text 유지 음성 테스트 한 줄을 같은 PR 또는 즉시 follow-up에 추가한다. #4694 promote 트리에는 넣지 않는다(별도 체리픽 요청이 없을 때). close-don't-rebase 대상 아님. 프리뷰 배포는 계획에 없음.

CI found one repository-policy failure, not a runtime assertion: adding the regression to the existing 8k-line catalog test grew a ratcheted file. I moved the same end-to-end reproduction into the focused flash-route-image-modalities.test.ts suite instead of raising the size baseline.\n\nNew exact head: 567cae3f8. Isolated post-fix checks: focused behavior + file-size ratchet 15/15, typecheck, structure, privacy, and diff check all pass. The product patch is unchanged.

- Around line 377-381: The custom overlay currently creates a skeletal member
before native-member injection, preventing native metadata from reaching
custom-only combos. Update the flow around memberByKey and
resolveComboCatalogMember so native injection occurs first, then apply only
explicitly configured custom fields; preserve the skip when a routed discovery
row already owns the key. Add regression coverage for openai/gpt-5.6-luna in a
non-nativeAlias combo with omitted custom capability fields, ensuring native
maxInputTokens and autoCompactTokenLimit are used.

Addressed the native-inheritance review on latest dev. New exact head: 21a9a209c. The custom overlay now runs after native-member injection, and the sparse ordinary-combo regression pins luna context, max-input, auto-compaction, and image modalities. Focused 10/10 and typecheck pass after the final commit; the earlier structure/privacy/file-size checks remain applicable to the unchanged product/doc files. @lidge-jun please review this exact head after CI completes.
