Summary

  • Add retainModels?: string[] provider configuration allowlist to guarantee configured models are preserved in catalog even if upstream live discovery does not report them (resolves [Feature]: config-level retainModels allow-list so operators keep configured models in the authoritative live catalog #1690).
  • When a provider uses live model discovery (such as Google Antigravity / Gemini or Vertex), models configured in retainModels will not be dropped by mergeConfiguredModelsIntoLiveCatalog.
  • Updated provider type definitions in src/types/provider.ts, config parsing in src/config.ts, model rename migration, and docs reference.
  • Added one-shot 404 diagnostic with proper generation reconciliation cleanup across provider state changes.

Verification

  • Added regression test suite tests/provider-retain-models.test.ts verifying:
    • Configured models in retainModels are retained when live discovery reports an empty or partial list.
    • Normal unlisted models not in retainModels continue to follow standard live discovery pruning behavior.
    • Full catalog sync retaining expected combo targets.
    • Diagnostic memo cleanup across generation reconciliation.
  • Verified cleanly rebased on latest origin/dev with strict typechecking and privacy scan 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.

📝 Walkthrough

Walkthrough

Changes

The provider configuration adds optional retainModels support. Values are normalized, validated, migrated, and documented. Live catalog merging preserves retained models omitted by discovery. Server routes emit one-time warnings when upstream reports retained models as unavailable.

Provider model retention

Layer / File(s) Summary
Retention configuration contract
src/types/provider.ts, src/config.ts, src/providers/model-rename-migration.ts, docs-site/src/content/docs/*/reference/configuration/providers.md
Adds, validates, normalizes, migrates, and documents the optional retainModels provider field.
Live catalog retention
src/codex/catalog/parsing.ts, src/codex/catalog/provider-fetch.ts
Includes retained IDs in discovery seeds, preserves omitted configured models, marks models retained without discovery, reports retained IDs separately from dropped IDs, and updates Cursor and Antigravity discovery handling.
Retained-model availability warnings
src/codex/catalog/provider-fetch.ts, src/server/chat-completions.ts, src/server/chat-native.ts, src/server/claude-messages.ts, src/server/responses/core.ts
Tracks retained models across catalog generations and emits one-time warnings for upstream model_not_found and HTTP 404 responses across provider protocols.
Retention behavior tests
tests/provider-retain-models.test.ts
Tests catalog retention, duplicate prevention, validation, visibility filtering, cache restoration, warning reconciliation, degraded discovery, stale-generation protection, and routed combo handling.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🔵 Low · up to 5d48a

The PR preserves configured models during live catalog discovery, but its retained-model diagnostic does not consistently cover all 404 and model-not-found response forms, which can reduce troubleshooting visibility for affected requests. This is a bounded follow-up risk and is mergeable with explicit owner awareness.

Preserve retained-model provenance before upstream dispatch.

retainModels is used only during catalog discovery. mergeConfiguredModelsIntoLiveCatalog() returns only models and droppedConfiguredIds, so dispatch cannot identify a retained model omitted by live discovery. Add provenance and emit the required one-shot diagnostic before dispatch.

#1690 구현임. 라이브 디스커버리가 빼도 retainModels에 있으면 카탈로그에 남김. 메인터가 유지한 이슈. draft. 4박스 아직 비어 있음.

핵심은 mergeConfiguredModelsIntoLiveCatalog (src/codex/catalog/provider-fetch.ts). providerRetainModels.has(id) 추가. 기본 prune은 그대로. configuredIdsretainModels를 합쳐서 시드함. 스키마는 src/config.ts providerConfigSchema, 타입은 src/types/provider.ts. 스플릿 이후 파일 맞음. 메가파일 되돌리는 패치 아님. MERGEABLE on dev.

테스트 tests/provider-retain-models.test.ts가 유지/드롭/중복/빈 라이브를 봄. unrelated-model은 드롭. 빈 retainModels는 지금이랑 같음. 리네임 마이그레이션 리스트에 retainModels 넣은 건 맞음.

빠진 건 1690 수용의 404 쪽. retain된 모델을 불렀을 때 한 번 경고하는 진단이 없음. 피커에 있는데 호출이 죽으면 또 같은 혼란임. CALLABLE_CONFIGURED_COMPATIBILITY_MODELS에 antigravity gemini-3.7-flash 시드는 없어도 됨. 설정이 그 역할.

초안이라 머지 열차 아님. CI/로컬 4박스 채우고 와. 동작은 방향 맞음.

해결방안: 호출 404 원샷 경고만 더하면 #1690 닫을 수 있음. 기본 동작 바꾸지 말 것.

The feature direction is valuable, and the latest commits address the Grok/CodeRabbit requests for whitespace validation, Cursor retention, and a retained-model dispatch diagnostic. The focused suite passes 8/8 and typecheck passes on d5e2dddae.

Two blockers remain before this can leave draft:

  1. The new diagnostic provenance can become stale. withConfiguredRetention only calls retainedWithoutDiscoveryRefs.set(...) when retainedConfiguredIds.length > 0; it never deletes the provider entry when a later live roster confirms the model or when retainModels is removed. reconcileProviderFetchWarnings also clears only lastDropWarnSignature, not either new map. A later unrelated 404 for that provider/model can therefore emit a false “retained via retainModels but omitted by discovery” warning. Replace the provider entry on every merge (set for nonempty, delete for empty) and reconcile both provenance/warning state across config generations. Add a gather-twice regression: first omitted+retained, then live-confirmed or retention-removed, followed by a 404 warning check.

  2. This head is currently 157 commits behind origin/dev and has only intake checks; it is still draft with 0/4 readiness boxes. Catalog gather/cache boundaries have changed substantially in that range, so the current green focused test is not exact-head evidence.

Please rebase onto the current dev, fix the provenance lifecycle, then run the focused suite plus full typecheck/test/privacy and exact-head CI before requesting approval.

Re-reviewed exact head 0baaf8c8e7c387e7f81e34a691749afa4edffeeb.

The new commits correctly replace the live-merge provenance entry (set for retained ids, delete when live discovery confirms them) and route Cursor retention through the shared merge helper. The focused suite passes 9/9 and typecheck passes on this head.

One lifecycle blocker from the previous review remains. reconcileProviderFetchWarnings() still clears only lastDropWarnSignature; it does not clear or reconcile retainedWithoutDiscoveryRefs or warnedRetained404Refs. Several catalog paths also return before withConfiguredRetention() can replace the provider entry: liveModels === false, OAuth without a usable token, and Cloud Code Assist without a project. Therefore this sequence still produces false diagnostics:

  1. a live gather omits model X and retainModels records X as retained;
  2. config changes remove retention, switch to static mode, or lose the OAuth/project prerequisite;
  3. generation reconciliation and the early-return gather leave the old provenance alive;
  4. a later unrelated 404 for provider/X emits the stale retainModels warning, and the one-shot memo can also suppress a future legitimate warning after reconfiguration.

Please make the retained provenance replacement/clear operation part of every provider catalog return boundary, or reconcile both provenance maps against each config generation. Add a gather-twice regression covering omitted+retained followed by retention removal/static or logged-out fallback, then assert that warnRetainedModel404Once stays silent; also prove a later legitimate retained generation can warn again.

This branch is still 157 commits behind current dev, remains draft, and enforce-target is red. Rebase after the lifecycle fix and rerun exact-head CI before requesting approval.

312-316: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Use one retained-model availability predicate across all server surfaces.

The three new call sites use different subsets of the supported signals. Apply response.status === 404 || upstreamCode === "model_not_found" consistently, including structured JSON failure paths.

  • src/server/chat-completions.ts#L312-L316: Move the warning call outside the upstreamCode === "model_not_found" classification branch and include HTTP 404.
  • src/server/chat-native.ts#L282-L285: Include HTTP 404 and reuse the warning for the structuredError(parsedJson) path.
  • src/server/claude-messages.ts#L791-L793: Parse error.code and include model_not_found in addition to HTTP 404.

The supplied src/codex/catalog/provider-fetch.ts contract covers both upstream HTTP 404 and model_not_found results.

- Line 84: Update the provider and adapter catalog documentation for
retainModels so IDs not covered by it or existing retention exceptions remain
subject to normal pruning, while documenting retained Vertex defaults,
compatibility models, and combo targets. Apply the same contract across the
provider guide, adapter reference, and ja, ko, ru, and zh-cn counterparts.
Document that Google Antigravity, Gemini, and Vertex use the google adapter with
account-specific live-first discovery and maintained/static fallback catalogs;
clarify that catalog visibility does not guarantee invocation support, and
preserve fail-closed adapter behavior plus upstream 404/model_not_found
diagnostics for retained models.

withConfiguredRetention merge passes instead of deleting
retainedWithoutDiscoveryRefs when the later forCache merge yields no IDs. Update
this state only from the raw discovery result, or equivalent generation-scoped

Antigravity paths; add a regression test covering both passes before
warnRetainedModel404Once.

Cover retained-model warnings in focused Bun tests. No test asserts warnRetainedModel404Once, one warning per provider/model, or all three paths. Add cases for plain HTTP 404 and error.code === "model_not_found" in Chat Completions, native Chat, and Claude Messages. Also include HTTP 404 in the predicates at src/server/chat-completions.ts:316 and src/server/chat-native.ts:285.

In `@src/server/chat-completions.ts` at line 316, Update the retained-model
warning predicates in the Chat Completions and native Chat handlers to recognize
plain HTTP 404 responses in addition to error.code === "model_not_found". Add
focused Bun tests covering both error forms across Chat Completions, native
Chat, and Claude Messages, asserting warnRetainedModel404Once emits exactly one
warning per provider/model.

Re-reviewed exact head ba9fc9fa821e7d0d1a259865e937cca2233f73a0. The generation-reconciliation change fixes the older stale-map case, but the current implementation still loses the provenance during an ordinary successful gather, so this cannot leave draft yet.

The blocking sequence is in fetchProviderModelsWithAuth:

  1. the first withConfiguredRetention(live, { retainComboTargets: false }) pass sees a configured retainModels ID missing from raw discovery and records it in retainedWithoutDiscoveryRefs;
  2. the next withConfiguredRetention(forCache, { warnDrops: true }) pass receives a catalog that already contains that retained row;
  3. mergeConfiguredModelsIntoLiveCatalog therefore returns no retainedConfiguredIds, and the current else branch deletes the provider entry.

Cursor, Antigravity, and cached return paths have the same multi-pass shape. A later upstream 404/model_not_found therefore has no retained provenance and the promised one-shot diagnostic is silently skipped. Keep the first raw-discovery result as generation-scoped metadata, or otherwise prevent later cache/return normalization passes from erasing it. Add a regression that executes both passes before calling warnRetainedModel404Once.

The endpoint integration is also incomplete and currently differs by wire:

  • Chat Completions and native Chat warn for structured model_not_found but not a plain HTTP 404.
  • Claude Messages warns for HTTP 404 but does not recognize structured error.code === "model_not_found".
  • Responses warns in the native passthrough failure branch, but the generic translated-adapter failure branch returns without calling the helper.

Please use one shared retained-model-unavailable predicate across these surfaces and add focused tests for both error forms plus one-warning-per-provider/model behavior. The current reconcileProviderFetchWarnings test only proves that the symbol is callable; it does not verify cleanup, suppression, or re-warning after a generation change.

Finally, keep the public contract synchronized: IDs not covered by retainModels or the existing Vertex-default, compatibility-model, and combo-target exceptions remain subject to pruning, and catalog visibility does not prove that upstream invocation is provisioned. Update the directly affected English pages and translated counterparts together.

This head is still Draft, has five unresolved review threads, and has no exact-head maintained CI beyond intake checks. After the provenance boundary, endpoint tests, documentation, and latest-dev rebase are complete, rerun focused tests, full typecheck/test/privacy, docs build, and exact-head CI before requesting re-review.

Re-reviewed exact head 638637130bf8e91c85c30b1adf40c09d0bf50279, including the owner/Grok and current CodeRabbit findings. The multi-pass deletion bug and plain-404 route coverage are improved. The focused suite passes 13/13, with typecheck, privacy scan, and git diff --check green.

Two provenance-ownership blockers remain:

  1. Generation reconciliation still breaks the diagnostic on a warm cache. reconcileProviderFetchWarnings() clears retainedWithoutDiscoveryRefs, but every fresh-cache, stale-cache, cooldown and discovery-failure return calls withConfiguredRetention() without recordRetainedDiagnostics. I reproduced this exactly: a live gather omitted retained-model and recorded it, a newer generation reconcile cleared the map, then a second gather inside the 60-second TTL made no upstream request and left the provenance absent. The subsequent upstream 404 therefore emits no retained-model warning. Add a real gather -> generation reconcile -> warm-cache gather -> 404 regression and restore provenance from generation-owned cache metadata or recompute it on every return boundary.

  2. The live paths mutate retainedWithoutDiscoveryRefs before setCached(..., cacheGeneration) proves that the result still owns the cache generation. If the provider/config/account changes while discovery is in flight, setCached can reject the stale writer after the old result has already replaced the diagnostic map. Commit catalog data and its provenance under the same generation guard; add a delayed stale-writer regression proving an old discovery cannot install or clear current diagnostic state.

Please also keep these maps private and expose narrow test helpers instead of exporting mutable production state solely for tests. This remains a draft with one readiness box open; do not approve it until the cache/provenance lifecycle is generation-consistent.

* feat(catalog): honor per-provider retainModels opt-in (closes #1690)

Operators can pin a model id so live discovery keeps it even when the
upstream catalog omits it. The new opt-in is purely additive: built-in
kimi/xai tables and the Vertex default continue to win, unknown ids are
never inflated, and the existing one-line diagnostic still flags ids the
live catalog dropped.

* feat(catalog): make retainModels self-sufficient and configurable (#1690)

Builds on the carried #2860 predicate. retainModels ids now enter the
configured seed (ordered union with the Vertex default and models), so a
retain-only id survives live discovery, liveModels:false, and gets the same
provider hints; selectedModels precedence is unchanged. Adds zod schema and
superRefine validation, management PATCH/DTO/safe-config plumbing,
ocx provider edit --retain-models <ids|->, rename-migration coverage,
discovery-flight fingerprint, and docs.

Design input: #2122 (union, schema, MODEL_ID_LISTS).

Closing as superseded by #3206 (6a6efa928), which lands #1690 on dev. Your design was the input for three pieces that shipped: folding retainModels into the configured seed so ids need not be repeated in models, the zod retainModels schema with nonBlankStringArrayConfigError, and adding the key to MODEL_ID_LISTS for rename migration. Thank you for that.

Not taken: the 404-time warnRetainedModel404Once diagnostic and CatalogModel.retainedWithoutDiscovery. They require module-level state and edits in four hot request handlers to repeat a message the upstream error body already carries; the existing dropped-ids diagnostic stays as the signal for ids that are not retained. The retention decision also lives in the one predicate the merge loop already consults (#2860's approach) rather than a second set beside it.
