Summary

Adds OAuth authorization with a Google account to the Add provider modal's Accounts tab, modelled on the Gemini authorization flow in sub2api. Two OAuth subtypes ship as two independent provider ids, each with its own account set and registry entry:

Row Provider id Endpoint Client
Gemini (Code Assist) gemini-cli cloudcode-pa.googleapis.com Gemini CLI public client (built in)
Gemini (AI Studio) gemini-ai-studio generativelanguage.googleapis.com operator-registered client (required)

Why two ids rather than one entry with a subtype field. Google gates the two behind different OAuth clients and different scopes, and the accounts are not interchangeable — a Code Assist credential cannot serve an AI Studio request. Separate ids let each keep its own credential set and its own login button state, and let the existing account plumbing work unmodified.

Flow (src/oauth/gemini-cli.ts): standard Google OAuth with PKCE (S256) on loopback port 51122 — deliberately distinct from Antigravity's 51121 so a Gemini login cannot land on a callback server already listening for an Antigravity one. For the Code Assist subtype the flow then discovers the Cloud Code Assist project via loadCodeAssist, falling back to onboardUser (polling the default entitled tier from allowedTiers) when the account has none yet. The discovered projectId is stored on the credential and injected into the request envelope by the google adapter, as the Antigravity flow already does.

Adapter (src/adapters/google.ts). The two Code Assist client families share the /v1internal:{action} endpoint and the response wrapper but are not interchangeable, so googleMode: "gemini-cli" selects the CLI's plain {model, project, request} envelope and GeminiCLI/<ver> User-Agent, versus Antigravity's {model, userAgent, requestType, project, requestId, request} and antigravity/ide/<ver>. The ai-studio subtype reuses the existing Generative Language transport but sends an OAuth bearer instead of x-goog-api-key, branching on authMode.

Fail-closed behaviour

  • AI Studio without credentials — Google's CLI client is not registered for the generative-language scopes, so rather than sending a request Google rejects as restricted_client, login fails immediately with a message naming the two env vars to set. The row's hint states the requirement before the user clicks.
  • Code Assist project discovery failure — login fails instead of persisting a credential. Otherwise status would read "logged in" while every request failed closed.
  • No allowBaseUrlOverride on either entry. Unlike Antigravity (which has daily and prod hosts and so needs the override), both Gemini endpoints are a single fixed host. Pinning them keeps the Google OAuth bearer from following an operator-set URL — see src/lib/destination-policy.ts and src/router.ts.
  • No extraMetadataAliases: ["gemini"]. That alias already belongs to the google entry; a second claim would shadow it. Both ids still resolve model metadata through jawcodeBundle: "google".

Credentials disclosure

src/oauth/gemini-cli.ts embeds the Gemini CLI's client id and secret. These are the public OAuth client identifiers Google ships inside the Gemini CLI binary, not user secrets — the same shape as the Antigravity client already on dev at src/oauth/google-antigravity.ts:18,20. Both are overridable via GEMINI_CLI_OAUTH_CLIENT_ID / GEMINI_CLI_OAUTH_CLIENT_SECRET for operators who prefer their own registered client. Tokens and refresh tokens are never logged.

Docs

Usage help was added to docs-site in both English and Simplified Chinese (guides/providers.md, zh-cn/guides/providers.md) plus the envelope/User-Agent distinction in reference/adapters.md: which subtype to pick, what each requires, how to register an AI Studio client, and the Code Assist project-discovery behaviour.

Screenshot

Add provider → Accounts, showing both new rows with their subtype hints. Rendered from the real ProviderCatalog component through the real buildAddModalAccountRows and LanguageProvider, locale pinned to English:

Add provider modal, Accounts tab, showing Gemini (AI Studio) and Gemini (Code Assist) rows with subtype hints

The logged-out sub-text is a new OAUTH_ROW_HINT_KEYS mapping: the two rows are subtypes of one Google account, so the provider id alone does not say what is being authorized. A live status (email or error) always wins over the hint.

Verification

Commands run locally:

  • bun run typecheck — clean
  • bun run privacy:scan — "Privacy scan passed"
  • bun run lint:gui — oxlint clean
  • bun run test tests/provider-registry-parity.test.ts tests/google-hardening.test.ts tests/gemini-cli-oauth.test.ts91 pass / 0 fail
  • Backend affected subset — 1975 pass / 9 fail / 1985 tests / 130 files
  • GUI bun test956 pass / 0 fail / 166 files
  • docs-site build — 393 pages, clean

On the 9 backend failures and bun run doctor:gui: all are pre-existing on dev, not introduced here. Verified by git stash push -u → re-run → identical failures by name → git stash pop. Every failure is in provider management validation, untouched by this branch.

New tests:

  • tests/gemini-cli-oauth.test.ts (322 lines, 23 tests) — subtype/client selection and the AI-Studio fail-closed path, Code Assist project discovery including the onboardUser fallback and tier selection, refresh with project re-discovery, the gemini-cli envelope and User-Agent, and the AI Studio OAuth-bearer transport.
  • gui/tests/gemini-oauth-account-rows.test.ts (4 tests) — both rows render as OAuth rows with the right labels; hints resolve through the real English catalog so a row pointing at a missing key fails here rather than shipping a bare key to users; unrelated rows get no hint; oauthTosRisk is elevated for gemini-cli and null for gemini-ai-studio.

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.

Sponsorship

pr-hygiene flags unsponsored_surface on src/oauth/gemini-cli.ts and src/oauth/index.ts. That is expected and correct: this adds an OAuth flow and credential handling, which MAINTAINERS.md requires a maintainer to security-review before applying maintainer-sponsored. The points most worth a reviewer's attention are the embedded public Gemini CLI client credentials (see Credentials disclosure above), the deliberate omission of allowBaseUrlOverride, and the two fail-closed paths.

Review readiness checklist

This PR stays in draft until every box below is ticked. Tick all four boxes once the requirements are met:

  • All CI tests are green on my local testing.

  • I pushed my PR to the latest dev commit.

  • I resolved all correct Codex and CodeRabbit findings.

  • My PR is ready for review.

Summary by CodeRabbit

New Features

  • Added Gemini OAuth sign-in with separate Code Assist and AI Studio options.
  • Added Gemini CLI support with project discovery, account management, token refresh, streaming, and model catalogs.
  • Added dashboard and CLI authentication flows, setup hints, configuration requirements, and risk notices.

Documentation

  • Added Gemini setup guidance and Google adapter reference details.

Localization

  • Added Gemini account labels and guidance across supported languages.

Adds "OAuth login (Gemini)" to the Add provider modal's Accounts tab: sign in
with a Google account and pick the OAuth subtype.

- gemini-cli (Code Assist): the Gemini CLI first-party client on
  cloudcode-pa. Shares the v1internal transport with Antigravity but is a
  distinct client family — plain {model, project, request} envelope and a
  GeminiCLI/<ver> User-Agent, never the antigravity IDE fingerprint. Project id
  is discovered via loadCodeAssist/onboardUser at login and on refresh.
- gemini-ai-studio: generativelanguage.googleapis.com with an OAuth bearer
  instead of an API key. Requires operator-registered client credentials and
  fails closed with an actionable message when they are unset.

Both endpoints stay pinned (no allowBaseUrlOverride) so the Google bearer
cannot follow an operator-set URL. gemini-cli sends the bare model id: the
-tiered spelling is an AI Studio deployment quirk that Code Assist does not
serve.

Docs: en + zh-cn provider guides and the adapters reference.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🔵 Low · up to 154fe

The change adds Gemini OAuth account options and project onboarding, but the new account labels may remain English in non-English locales and failed onboarding can wait an unnecessary extra interval after the final poll. The PR is mergeable with explicit owner awareness and follow-up on these bounded issues.

Use an AI Studio-specific Gemini catalog.

GEMINI_CLI_* is scoped to the Cloud Code Assist host, but gemini-ai-studio uses https://generativelanguage.googleapis.com. Sharing these constants can expose a Code Assist-only model on the AI Studio route and cause a 404. The shared metadata also marks gemini-3.1-pro-preview as image-capable, unlike the google entry.

Define explicit AI Studio metadata, or rename the constants only if both hosts support identical models and capabilities. Do not use spread copies of the CLI constants.

Antigravity랑 다른 클라이언트 패밀리를 맞춘 거임. 지금 dev src/adapters/google.tsgoogleMode === "cloud-code-assist"만 CCA 엔벨로프랑 antigravity/ide/... UA를 씀. Gemini CLI 토큰으로 그 경로 타면 클라이언트 패밀리 불일치임. AI Studio 기본 경로는 x-goog-api-key라 OAuth 베어러가 거절됨. 구멍은 기능 공백임. 핫픽스 아님.

이 PR이 서브타입을 프로바이더 두 개로 나눔. gemini-cli (googleMode: "gemini-cli", cloudcode-pa, 핀 호스트, allowBaseUrlOverride 없음)랑 gemini-ai-studio (googleMode: "ai-studio", generativelanguage.googleapis.com, 오퍼레이터 클라이언트 필수). src/oauth/gemini-cli.ts가 PKCE. Code Assist는 loadCodeAssist/onboardUserprojectId 없으면 로그인 실패. AI Studio는 GEMINI_AI_STUDIO_OAUTH_CLIENT_ID/SECRET 없으면 GeminiOAuthClientNotConfiguredError. 어댑터가 CLI는 {model, project, request} + GeminiCLI/<ver> UA, AI Studio OAuth는 Bearer. src/server/responses/core.tsgemini-cli에도 스냅샷 projectId를 붙임. 토큰/프로젝트 세대 섞임 방지. 방향은 맞음.

src/types/provider.tsGoogleAdapterMode를 넣고 배럴 src/types.ts가 재수출함. 지금 dev가 이미 AUTO-SPLIT 배럴임 (types.ts:1). 스플릿이 이 PR을 삼키는 형태 아님. 닫고 다시 짜라는 신호 아님. registry.ts 시드 두 줄 + 모드 유니온 확장임. #2217/#2227 modelWireDefaults 안 건드림. #2188 사이드카, #2190 x_search랑 섞지 말 것. Gemini CLI 카탈로그를 Antigravity 에이전트 와이어 id로 채우지 않은 것도 맞음. 그 id는 CLI 크레덴셜에 404임.

프로세스 게이트가 안 열렸음. intake: hygiene-blocked / unsponsored_surfacesrc/oauth/gemini-cli.ts, src/oauth/index.ts. 임베디드 Gemini CLI 공개 클라이언트 시크릿이 Antigravity랑 같은 패턴임. 메인터 보안 리뷰 전에 maintainer-sponsored 금지. draft고 체크리스트 2/4. enforce-target이 몇 번 레드였음. 최신 dev 03735eca6에 진짜 올라가 있는지 확인해야 함.

주의 몇 개. 로그인 UA가 GeminiCLI/0.1.5 (Windows; AMD64)로 하드코딩임. 어댑터 geminiCliUserAgent()process.platform/arch를 씀. 온보딩이랑 실제 요청 클라이언트 셰이프가 다름. refreshGeminiToken이 재발견 실패하면 projectId 없이 creds만 반환함. 스토어가 통째로 덮으면 다음 턴이 "requires a discovered Cloud Code Assist project id"로 죽음. 기존 projectId 유지해야 함. AI Studio 스코프에 userinfo.email이 없음. GUI 라벨/임포트 validateGeminiImportCredential이 userinfo를 때림. isGeminiOAuthSubtypeConfigured가 대시보드 비활성화에 안 붙으면 AI Studio 행이 항상 보임. ㅋㅋ 눌러서 에러 보는 거임.

테스트가 서브타입 매핑, AI Studio fail-closed, 레지스트리 패리티, GUI 힌트(실제 en 카탈로그), 어댑터 엔벨로프를 잠금. 범위는 큼. +oauth 모듈 + google 어댑터 + 레지스트리 + GUI. 비전공자가 유지하기엔 새 인증 면이 무거움. 2.28 블로커 아님. 프리뷰 디플로이 계획에도 없음.

해결방안: 메인터가 oauth 표면 보안 리뷰하고 maintainer-sponsored 단 뒤에 hygiene 통과, draft 해제. refresh에서 projectId 보존. 로그인 UA를 어댑터랑 맞추거나 고정을 문서화. AI Studio 행은 클라이언트 미설정이면 비활성. 스플릿이 GoogleAdapterMode를 또 옮기면 리베이스하지 말고 닫고 다시 짜라. 지금은 types/provider.ts가 맞는 자리임.

Separate the onboarding retry budgets and keep the failure reason:

- onboardProject gave transient 429/5xx retries and in-progress polls one
  shared counter, so a couple of 5xx responses could exhaust the budget
  before Google finished provisioning. Transient retries now draw on their
  own budget.
- Onboarding that is merely slow was reported the same way as an account
  without Code Assist access, sending users to look for a problem that does
  not exist. discoverGeminiProjectOutcome now returns ready/pending/
  unavailable and the login error distinguishes the two.
- discoverGeminiProject keeps its boolean-ish contract for the refresh path,
  which stays lenient on purpose.

Pin the Code Assist refresh policy to lazy-only. Each refresh also re-runs
project discovery against Google's own CLI client identifiers, so proactive
refresh would multiply traffic under identifiers we do not own.

Replace a tautological subtype test with two that assert real contracts, and
add regression coverage for the separated budgets, the pending outcome, the
hard-4xx outcome, the exhausted transient budget, and the refresh policy.

Docs: correct the gemini-cli host in the adapters reference (it is
cloudcode-pa, not the Antigravity daily- host), and mirror the English
Gemini updates into the six remaining locale guides — provider table rows,
both login commands, the OAuth auth-mode row, the preset count, and the
full OAuth login (Gemini) section.

Thanks for the review — pushed 154fe3b with the fixes. Here is what I took and what I skipped, with the reasoning for each.

Accepted

1. Stale locale docs — you named ja / ko / ru, but the same five antigravity-only spots exist in fr / tr / zh-tw as well, so I widened the fix to all six non-English locales. Each now carries the mirrored ocx login gemini-cli / ocx login gemini-ai-studio lines, both provider-table rows, the corrected preset count (8 → 10), Gemini added to the oauth auth-mode row, and a fully translated OAuth login (Gemini) section placed before that locale's Antigravity Cockpit Tools heading. CRLF endings preserved. docs-site builds clean at 393 pages.

2. adapters.md hostname — fixed. Both cloud-code-assist and gemini-cli rows now read cloudcode-pa.googleapis.com/v1internal:{action}.

4. Onboarding retry budget — split into two counters. Transient 429/5xx retries now draw from ONBOARD_TRANSIENT_ATTEMPTS instead of sharing the in-progress polling budget; previously two 503s could exhaust the budget before provisioning finished, and the login then blamed the account's entitlement for what was really a timeout. onboardProject also returns a discriminated ready / pending / unavailable outcome so the two failure modes produce different user-facing messages instead of collapsing into "no access". refreshGeminiToken stays lenient on discovery failure by design — a good token should not fail the whole account because discovery is briefly unavailable. Four regression tests cover it.

5. Refresh policy — pinned defaultRefreshPolicy: "lazy-only" on the code-assist entry, matching the existing nous / github-copilot precedent. The rationale is a bit stronger than stated in the finding: every Code Assist refresh also re-runs project discovery against Google's own first-party CLI client identifiers, so a proactive policy would multiply that traffic under identifiers we do not own. Added a test, because the unset default is also "lazy-only" — a silent drift to "proactive" would otherwise pass unnoticed.

9. Hollow subtype test — the original assertion was tautological. Replaced with two tests that assert something falsifiable: that both subtypes derive from the registry with a real providerConfig / defaultModel, and that the registry pins each subtype's googleMode and host.

Skipped, with reasons

3. GUI labels not routed through i18ngui/AGENTS.md:20 explicitly lists company / product names (its own examples: OpenAI, Anthropic, GitHub, Codex) as allowed literals without i18n keys, and all eight sibling provider entries in the same list are hardcoded the same way. Routing only these two through i18n would make them inconsistent with every neighbor. bun run lint:i18n is clean.

6. AI Studio model catalog said to be missing image models — checked against the authoritative src/generated/model-metadata.ts: all three models in question are already text,image, and the google entry already lists all three. Nothing to change.

Validation

  • bun run test tests/gemini-cli-oauth.test.ts → 29 pass / 0 fail
  • bun run typecheck, bun run privacy:scan, bun run lint:gui, gui bun run lint:i18n → all clean
  • gui bun run test → 956 pass / 0 fail
  • docs-site build → 393 pages, complete
  • Branch is level with dev (git rev-list --count HEAD..origin/dev = 0)

One note on CI: PR hygiene / enforce-target fail on unsponsored_surface because this PR touches src/oauth/, which the gate restricts to PRs carrying the maintainer-sponsored label. I do not have permission to apply that label, and the only way to clear it from my side would be to move the OAuth code out of src/oauth/, which would defeat the change. It needs a maintainer to apply the label after the security review that MAINTAINERS.md requires for auth changes.

🚀 Performance & Scalability | 🟡 Minor | ⚡ Quick win

Do not wait after the final onboarding poll.

At Line 261, polls can reach ONBOARD_ATTEMPTS. Line 262 then waits for ONBOARD_POLL_MS even though the loop exits immediately afterward. This adds two seconds to the pending-login result and delays cancellation handling.

Proposed fix
     polls += 1;
-    await new Promise(resolve => setTimeout(resolve, ONBOARD_POLL_MS));
+    if (polls < ONBOARD_ATTEMPTS) {
+      await new Promise(resolve => setTimeout(resolve, ONBOARD_POLL_MS));
+    }

Reviewed exact head 154fe3be7142388396287f37e2e74cb5f38f7b35. I independently checked the current automated findings and the author response.

The hardcoded Gemini product-label finding is a false positive under gui/AGENTS.md, which explicitly allows company/product names; I replied and resolved that thread.

Two blockers remain:

  1. gemini-ai-studio targets generativelanguage.googleapis.com but still reuses the Cloud Code Assist-scoped GEMINI_CLI_* model and capability constants. Generic generated metadata does not prove that the OAuth AI Studio endpoint exposes the same account-scoped catalog. Use endpoint-specific metadata or provide a real AI Studio account/endpoint contract test that establishes identical model ids and capabilities before sharing a named constant.
  2. onboardProject still sleeps for ONBOARD_POLL_MS after incrementing the final poll to ONBOARD_ATTEMPTS, adding an unconditional two-second delay before the pending result. Skip the sleep when no poll remains and add a bounded timing/call-count regression.

This OAuth/security surface is also 62 integration commits behind current dev. Rebase first, preserve the existing previous-credential metadata merge in the shared refresh path, rerun the focused OAuth/GUI/docs checks and exact-head CI, and request a fresh security review before applying maintainer-sponsored or merging.
