Summary

TL;DR: I have repeatedly seen newly available provider models become enabled despite New Model Policy being set to Off. My expectation is that Off keeps newly discovered provider models disabled, regardless of whether the UI currently displays the NEW badge. The badge reports recorded discovery state; it should not determine whether the policy applies. I observed this on Venice, but the reproduced defects are in shared catalog publication paths.

Apply the effective new-model policy before HTTP discovery, startup/explicit sync, or client export publishes newly discovered provider models. Previously, a provider adding model C after the known A/B baseline could expose C despite newModelPolicy: "off", without recording it as a recent arrival. Regression tests reproduce all three paths and now pass. They demonstrate shared defects consistent with the report, not a retrospective reconstruction of the original installation.

The shared fetcher now reconciles authoritative discoveries before visibility filtering. For a matching persisted configuration, it commits the known-model baseline, arrival badges, and automatic disables together under the existing config mutation lock. It checks provider inventory and cache revisions, rebases concurrent changes, and adopts the committed discovery fields together with their live merge baselines. This preserves an operator's subsequent manual re-enable. Synthetic callers only update their own in-memory configuration.

Repeated read-side discovery does not advance removal grace counters; convergence retains removal accounting. First-fetch bootstrap, explicit selections, custom rows, and degraded discovery preserve the existing policy behavior. /v1/models returns retryable HTTP 503 if a persisted decision cannot be committed, instead of publishing the unrecorded arrival.

Startup and explicit sync use a separate catalog gather path. syncCatalogModels now reconciles authoritative discoveries after catalog evidence revalidation and before writing the catalog, using the same persistence helper and the existing catalog-to-config lock order. If the discovery decision cannot be committed, sync refuses publication and leaves the existing catalog unchanged. This covers the ocx start startup wrapper and the catalog path used by POST /api/sync.

loadExportModels also gathers independently. It now reconciles after revalidating its admitted configuration and captured cache revisions, then captures the resulting configuration for projection and preview retention. A superseded gather keeps the existing response semantics using a detached policy projection, persists nothing, and retains no preview. Failed persistence or an uncopyable fallback projection raises the existing retryable CatalogGatherBusyError instead of returning unchecked rows. Explicitly supplied rosters and read-only previews remain free of discovery writes.

Coverage uses the real proxy with a synthetic OpenAI-compatible provider and temporary homes. It exercises all four global/provider on/off combinations, existing manual exclusions, persisted arrivals, re-enable followed by refresh, and failed persistence. The startup tests drive the real startup wrapper, sync, gather, and catalog writer; only unrelated admission and client-config injection are stubbed. They verify off/on behavior, manual re-enable, failed persistence, and fresh upstream reads. No vendor account or credentials are required. The defect is in shared service logic, not a Venice-specific adapter.

Related: #2464 and #2609 introduced the off policy. #5617 concerns explicit global model visibility and is a separate change. Direct inference routing is unchanged.

Publication-path audit:

Path Policy boundary
HTTP discovery/dashboard and consumers of fetchAllModels Shared discovery finalizer, covered by HTTP and persistence tests
Service startup and explicit sync Retained catalog sync, covered by startup integration tests
Client configuration exports and integration rosters loadExportModels, covered by export and snapshot/race tests
Catalog convergence Existing reconciliation on the candidate before visibility projection
Prewarming, context-window lookup, initial selection Raw gathering with no automatic publication of a new client model list
Read-only integration previews Consume an already retained export snapshot; never gather

Explicit remote-catalog imports, bundled native models, configured custom models/combos, and the existing first-discovery bootstrap behavior remain outside this live-provider-arrival fix. The audit establishes the current call paths; it is not a guarantee against future callers bypassing the contract.

Suggested follow-up: Consider a phased consolidation of the catalog publication paths: maintain an inventory of their entry points, give them shared behavioral contract tests, and incrementally make the policy decision an explicit prerequisite of publication. Raw discovery, read-only previews, and persistence each have distinct responsibilities and should retain those boundaries. This is a separate architectural follow-up; this PR stays focused on reproduced policy omissions.

Verification

Scope decision: the additional guard and two tests for an already-stale runtime configuration were withdrawn. CodeRabbit's scenario (another writer has already changed the persisted provider inventory and model choice before discovery starts) remains unaddressed by this PR. General disk/live configuration refresh and reconciliation are deferred to a separate change; this PR covers newly discovered models through the existing discovery, sync, and export paths. This is a scope decision, not a claim that the review scenario cannot occur or has been fixed.

Validation after narrowing the change:

  • bun run scripts/test.ts tests/providers/new-model-policy-runtime.test.ts tests/server/server-new-model-policy-arrival.test.ts tests/server/model-export-new-model-policy.test.ts tests/codex-integration/codex-sync-new-model-policy.test.ts — 25 passed, 0 failed, 196 assertions.
  • bun run typecheck, bun run structure:check, bun run privacy:scan, and git diff --check — passed.

Earlier focused Windows validation (the source tree has returned exactly to the revision validated below):

  • bun run scripts/test.ts ./tests/server/server-new-model-policy-arrival.test.ts ./tests/providers/new-model-policy-runtime.test.ts ./tests/server/model-discovery-management-api.test.ts ./tests/providers/initial-model-selection.test.ts — 39 passed, 0 failed across four explicitly named files, including five HTTP integration cases and nine discovery-persistence cases.
  • bun run scripts/test.ts tests/providers/new-model-policy.test.ts — 15 passed, 0 failed, including removal-grace controls; run by the review subagent.
  • bun run scripts/test.ts tests/codex-integration/codex-sync-new-model-policy.test.ts — 4 passed, 0 failed, 34 assertions. Before the startup fix, the off cases exposed model C and the on case failed to record its arrival.
  • bun run scripts/test.ts tests/server/model-export-new-model-policy.test.ts — 7 passed, 0 failed, 51 assertions. Before the export fix, Off exposed model C, arrivals were not persisted, and the persistence-failure case returned a roster. Covers the first retained preview and a real mid-gather configuration edit.
  • bun run scripts/test.ts tests/server/management-model-roster.test.ts tests/server/management-model-roster-gather-race.test.ts — 18 passed, 0 failed; supplied-roster purity, preview identity, and concurrent config/cache changes.
  • bun run scripts/test.ts tests/server/management-client-config-route.test.ts -t 'disabled models are filtered|model order and dedupe|a catalog failure is 503|expired management roster|explicit off survives|bare Anthropic provider config' — 6 passed, 0 failed, 35 unrelated cases filtered out.
  • bun run scripts/test.ts ./tests/test-layout-tooling.test.ts -t 'a file that only the regex seeds know' — 1 passed, 15 unrelated cases filtered out.
  • bun run typecheck — passed (the repository command checks source files).
  • bun run structure:check — passed.
  • bun run privacy:scan — passed.
  • cd docs-site && bun run build — passed using the installed dependencies; 545 pages and 74,716 internal links checked.
  • git diff --check — passed.

Checklist

  • Scope stays focused and avoids unrelated cleanup.
  • Docs or release notes were updated when needed.
  • Security-sensitive changes were reviewed for secrets, auth, and unsafe defaults. The change adds no auth or credential handling; fixtures are synthetic and local listeners bind loopback. Persistence uses the existing mutation boundary and emits no config identity or secrets.

Review readiness checklist

  • Required local validation passed; commands, results, and any full-suite exception are documented.
  • I pushed my PR to a recent dev commit (at most 10 behind; a maintainer may still ask for the exact tip before merge).
  • I resolved all correct Codex and CodeRabbit findings.
  • My PR is ready for review.

Summary by CodeRabbit

  • New Features

    • Newly discovered models now follow the configured policy before appearing in model lists, exports, dashboards, and Codex sync.
    • Manually re-enabled models remain enabled across later refreshes and exports.
    • Model updates are rejected when discovery results are stale or changes cannot be saved, helping prevent outdated catalogs from being published.
  • Documentation

    • Updated guides to explain when model policies apply and how arrivals, removals, and manual choices affect model visibility.

Add generic HTTP integration coverage for a provider catalog growing from A/B to A/B/C before convergence. The two off-policy cases intentionally fail on current dev because C is exposed; the two on-policy controls pass. Existing disabled B remains hidden throughout. Add pure policy override controls and use isolated temporary homes and owned server cleanup.

Focused validation: HTTP integration 2 pass / 2 expected failures; policy and management API files 12 pass; layout seed check 1 pass. Typecheck and privacy scan pass. No test:changed or full suite run. This is a reproduction commit, not a production fix.

Model discovery policy

Layer / File(s) Summary
Policy modes and discovery finalization
src/providers/new-model-policy.ts, src/providers/new-model-policy-runtime.ts, src/config/live-reconcile.ts, tests/providers/*
Discovery mode preserves removal state while convergence mode retains grace-counting behavior. Discovery finalization validates configuration identity, provider cache revisions, persistence, and concurrent mutations. Committed discovery state updates live merge baselines.
Publication and synchronization consumers
src/server/management/shared.ts, src/server/management/model-rows.ts, src/codex/catalog/retained-sync.ts, tests/server/*, tests/codex-integration/*
Model reads, exports, and Codex synchronization finalize discovery before publication. Stale or failed commits use detached projections or raise CatalogGatherBusyError.
Documented catalog contract
structure/*.md, docs-site/src/content/docs/guides/model-routing.md
Documentation describes policy ordering, persistence checks, revision handling, retained gathers, previews, synchronization, exports, and manual re-enablement.

Suggested reviewers: lidge-jun, ingwannu

Merge Risk: 🔵 Low · up to 5c7a0

The change looks mergeable with two small follow-ups. In an uncommon case where the running server's config has drifted from disk, a newly discovered model's automatic hide or show decision could later be written over a newer on-disk value. The translated model-routing guides also do not yet describe the new-model policy.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 5c7a0

The change strengthens publication controls and preserves operator choices when saved settings remain valid. Recovery when saved settings are unavailable or differ from running settings is not sufficiently established. No introduced security vulnerability was verified.

No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The affected state is shared across configured providers within one configuration home and feeds HTTP discovery, client exports, and the owned catalog. The inspected transition does not establish broader tenant, environment, or credential authority.

Trust Boundaries and Controls

  • observed — Production gathering supplies authoritative-provider outcomes to finalization. Reconciliation excludes custom rows and providers with live discovery disabled, while persisted mutation rechecks configuration identity and provider revisions before accepting discovery state.
  • observed — Stale export gathering uses a detached policy projection without retaining the snapshot. Catalog synchronization finalizes before writing and refuses a failed finalization, providing counterevidence against publication through those failure paths.

Resilience and Maintainability Implications

  • observed — Unavailable persistence and mutation exceptions refuse persisted finalization without adopting tentative discovery state. The mutation coordinator retries changed file snapshots, and committed adoption keeps visibility state aligned with its live merge baseline.

이 PR은 “새 모델 끄기(off)”가 켜져 있어도, 카탈로그를 맞추기 전에 GET /v1/models가 방금 나타난 모델을 목록에 넣는 구멍을 재현합니다. 실제 수정 코드는 없고, 실패하는 통합 테스트와 통과하는 정책 단위 테스트만 넣었습니다. base는 dev입니다.

흐름은 이렇습니다. 가짜 OpenAI 호환 업스트림이 처음엔 A·B만 주고, 그다음 C를 더합니다. 설정에는 A·B가 이미 알려진 상태이고, B는 수동으로 꺼 두었으며, 허용 목록(selectedModels)은 없습니다. 그 제공자 캐시만 지운 뒤 /v1/models를 다시 읽습니다. 카탈로그 맞추기(reconcileSuccessfulModelDiscoveries)는 호출하지 않습니다. 기대는 off면 C가 안 보이고, on이면 C가 보이는 것입니다. 지금은 off 두 케이스에서 C가 보여서 깨집니다. on 두 케이스와 “B는 계속 숨김”은 통과합니다. 레이아웃 맵에도 새 테스트 파일을 넣었습니다.

관련 이슈 #2464와 구현 #2609가 off 정책을 넣었고, 열린 #5617은 “전역으로 모델을 보이게/안 보이게” 쪽에 가깝습니다. 이번 PR은 “새로 발견된 ID가 수렴 전에 목록에 나오는지”라서 중복으로 보이지 않습니다. types.ts/config.ts 분할과 겹치는 변경은 없습니다. draft이고, 작성자도 off 단언이 빨간 동안은 머지하지 말라고 적어 두었습니다.

라인 - tests/server/server-new-model-policy-arrival.test.ts (off 두 케이스): 의도적으로 빨간 단언입니다. 런타임 수정 없이 draft를 풀거나 머지하면 CI/게이트가 이 파일에서 막힙니다. test.failing 같은 예상 실패 래퍼도 없습니다. 재현용으로는 분명하지만, 이 커밋만 dev에 올리면 빨간 스위트가 됩니다.

라인 - HTTP 경로 vs reconcileSuccessfulModelDiscoveries: 단위 테스트(tests/providers/new-model-policy.test.ts)는 맞추기를 직접 부르면 provider override까지 통과합니다. 구멍은 fetchAllModels / 목록 필터가 이미 저장된 disabled·selected만 보고, known baseline + effective off로 새 도착을 가리지 않는 쪽에 있습니다. 이 PR은 그 지점을 가리키기만 하고, 어디에 막을지(목록 필터 / 발견 직후 맞추기 / disabled 기록)는 아직 없습니다.

라인 - 범위: 픽스처는 openai-chat + liveModels + 루프백 업스트림 한 길입니다. 다른 어댑터·프리셋 허용 목록·첫 fetch 기준선(baseline bootstrap)·발견 실패(degraded)는 이 재현에 없습니다. 좁은 재현으로는 충분하고, 수정 PR에서는 그 경계도 같이 봐야 합니다.

메인테이너의 판단이 필요한 지점

빨간 재현 테스트를 수정 PR과 한배에 둘지, 재현만 먼저 두고 draft로 유지할지. off일 때 C를 숨기는 곳을 목록 응답 필터로 둘지, 발견 성공 시 맞추기를 돌려 disabledModels에 넣을지. 목록에서만 가리고 설정에는 안 남기면, 나중에 맞추기가 돌 때와 어긋날 수 있습니다. #5617(전역 가시성)과 이 재현을 같은 PR로 묶을지, 각각 둘지.

너의 추천

재현 방향은 맞습니다. draft로 두고, 런타임 수정을 같은 줄기(또는 바로 이은 PR)에 넣어 off 단언이 초록이 된 뒤에만 ready/머지하세요. 막기는 HTTP 목록이 known baseline + effectiveNewModelPolicy를 보도록 하는 쪽이 이 재현과 가장 잘 맞습니다. 맞추기만 기하면 TTL·캐시 사이에 또 새어 나올 수 있습니다. #5617은 닫지 말고 주제만 구분해 두세요. 미리보기 배포 이야기는 이 PR과 무관합니다.

… publication (#6331)

Carries #6260 with a maintainer fix: a file-loaded config keeps its file provenance after discovery inventory drift, so stale discovery is refused under the mutation coordinator instead of disabling a model in memory that a later unrelated save would persist over the operator's choice.

Landed on dev through maintainer carry #6331, with a Co-authored-by trailer for you. One addition from review: a file-loaded config now keeps its file provenance after discovery inventory drift, so stale discovery is refused instead of disabling a model in memory that a later save would persist (the CodeRabbit finding deferred here). The localized docs were also aligned. Thank you!
