feat(antigravity): expose membership plan in account UI

[juzijia]

Summary

• Surface Google Antigravity membership labels from the existing loadCodeAssist paidTier response.
• Preserve explicit tri-state semantics across refresh and credential storage: missing observation keeps the previous plan, a recognized label updates it, and an explicit unknown tier clears it.
• Expose the stored plan through the generic OAuth account API and render it as the shared green plan badge in the provider UI.
• Reuse the existing Antigravity discovery request; this does not add a new Google endpoint or quota-based plan inference.

Verification

• bun test tests/adapters/google/google-antigravity-oauth.test.ts — 12 passed, 0 failed.
• Backend TypeScript check — passed.
• GUI TypeScript check — passed.
• GUI oxlint — passed.
• git diff --check — passed.
• Manual runtime verification observed both free-tier → Free and g1-pro-tier / Google AI Pro from cloudcode-pa.googleapis.com/v1internal:loadCodeAssist, and the badges rendered in the account list.

• A broader branch validation previously reported one inherited file-size ratchet failure in tests/responses/responses-state.test.ts; the same file length/limit exists in the parent and is unrelated to this change.

Checklist

• Scope stays focused and avoids unrelated cleanup.
• Docs or release notes were updated when needed. (No docs/release-note change required for this focused UI/account metadata addition.)
• Security-sensitive changes were reviewed for secrets, auth, and unsafe defaults.

Review readiness checklist

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

• 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
  • Google Antigravity accounts can display a detected subscription plan, such as Free or a named tier.
  • Account plans are retained when refresh data omits them and updated when a new plan is detected.
• Bug Fixes
  • Unknown plan information no longer appears as a recognized tier.

📝 Walkthrough

Walkthrough

Google Antigravity OAuth discovery now reports subscription plans. OAuth credentials retain and expose those values through account summaries, and provider workspace rows display a plan beside the account label when present.

Changes

Antigravity plan reporting

Layer / File(s)	Summary
Discover and attach plan values src/oauth/types.ts, src/oauth/google-antigravity.ts, tests/adapters/google/google-antigravity-oauth.test.ts	Credentials now allow an optional plan. Antigravity discovery maps free-tier to Free, retains matching Google AI <name> labels, and returns null for other present or invalid tier values. OAuth exchange includes a discovered plan. Tests cover tier mapping and refresh behavior.
Retain, validate, and expose plans src/oauth/google-antigravity.ts, src/oauth/index.ts, src/oauth/store.ts, tests/adapters/google/google-antigravity-oauth.test.ts	Refresh includes available plan data. Credential merging retains the previous plan when refresh omits one. Credential storage trims and validates plan labels while preserving explicit null. Account summaries expose the stored plan or null; persistence tests check credential retrieval and login status.
Display plans in provider rows gui/src/components/provider-workspace/types.ts, gui/src/hooks/useProviderAccountPools.ts, gui/src/components/provider-workspace/ProviderAuthPanel.tsx, gui/src/styles/provider-workspace-settings.css	Provider account types accept nullable plans. OAuth rows show the plan beside the account label when present, with flex styling for the heading.

Merge Risk: 🔵 Low · up to 22a62

Plans appear in account rows, but screen-reader users cannot hear the plan from the button, and “Free” remains English in other locales. These are bounded issues that can be fixed before merge or accepted for follow-up.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 22a62

The membership label appears to be display-only and does not change sign-in or request permissions. One refresh failure path can leave an older label visible after the provider has reported an unknown tier.

Retained concerns

• Low · architecture · inferred: If discovery observes an explicitly unknown tier but finds no project ID, an onboarding exception is caught as an empty discovery result during refresh. The previous plan is then retained rather than cleared, contrary to the new tri-state credential contract.

Security review details

Security Blast Radius

• inferred — The newly exposed data is a provider-reported account label reaching stored credentials, account summaries and the UI. The examined path does not grant additional token, project or request-routing authority.

Trust Boundaries and Controls

• observed — The provider response is checked for recognizable tier values; credential normalization trims labels, limits them to 128 characters and rejects control characters. The UI interpolates the label as text rather than HTML.

Resilience and Maintainability Implications

• observed — Credential refresh persists through an account-ID-targeted, generation-checked store mutation, limiting stale refresh writes to the wrong credential generation.

Hardening Proposals

• proposed — Decide whether a tier observed before onboarding fails should remain authoritative; if so, preserve that observation independently of the onboarding result while retaining the existing project-ID login gate.

리뷰 · 우선순위 62 / 80

바탕 브랜치는 dev예요. src/types.ts와 src/config.ts를 나누는 글은 아니에요. 멤버 등급 배지를 넣는 다른 열린 PR은 없어요.

Google Antigravity 계정 이름 옆에 등급을 녹색 배지로 보여 줘요. 로그인할 때와 토큰을 새로 받을 때, 원래 부르던 loadCodeAssist 응답의 paidTier를 읽어요. 그 칸이 없으면 저장해 둔 등급을 그대로 둬요. id가 free-tier면 Free로 저장해요. 이름이 Google AI 로 시작하면 그 이름을 그대로 저장해요. 규칙에 안 맞으면 등급을 비워요. 계정 목록의 plan이 배지 글자가 돼요. 파일에 넣을 때 128자를 넘거나 제어 문자가 있으면 그 칸만 버려요. 설명에는 이 테스트 12개가 통과했다고 적혀 있어요.

라인 - src/oauth/google-antigravity.ts extractPaidTierPlan — 무료를 영어 Free로 저장하고, ProviderAuthPanel.tsx가 그 글자를 그대로 그려요. 번역은 이미 있어요. 키 modal.badge.free의 한국어는 무료, 일본어는 無料, 프랑스어는 Gratuit예요. 한국어 화면에서도 무료 계정은 Free로 나와요. Google AI Pro 같은 상품 이름은 받은 글자 그대로 두면 돼요.

라인 - gui/src/components/provider-workspace/ProviderAuthPanel.tsx 542행 — 버튼 aria-label은 계정 이름만 말해요. 지금 쓰는 계정이면 그 말도 붙어요. 등급 배지는 버튼 안에 있어요. 화면 읽기는 aria-label만 읽고, 안의 배지 글은 건너뛰어요.

메인테이너의 판단이 필요한 지점

이 PR은 초안이에요. src/oauth/를 고쳐서 위생 검사가 unsponsored_surface로 실패해요. 메인테이너가 본 뒤에 maintainer-sponsored를 붙여야 초안이 풀려요. 부르는 주소는 원래의 loadCodeAssist 하나예요. 등급 글자만 계정 파일에 더해요.

이름 규칙에 안 맞는 paidTier는 예전 배지를 지워요. 유료 이름이 Google AI 로 시작하지 않으면 배지가 사라져요. 지울지, 마지막으로 알았던 등급을 남길지 정해 주세요.

너의 추천

무료 배지는 modal.badge.free로 그리세요. 상품 이름은 그대로 두세요. 버튼 이름에 등급을 넣으세요. 그 둘을 고치고 maintainer-sponsored가 붙은 뒤에 머지하세요.

Thanks, @juzijia. Showing the Antigravity membership plan in the account UI is useful.

This release train's GUI lane is not taking it, because every file it changes belongs to the account-pool work currently in flight: ProviderAuthPanel.tsx, useProviderAccountPools.ts, provider-workspace/types.ts and the OAuth account store. git merge-tree against current dev already conflicts in gui/src/components/provider-workspace/types.ts, and the open account-pool PR #6106 changes the same panel. Once that lands, please rebase onto dev; the plan badge can then be reviewed against the new panel. I'm leaving this PR open.

[Ingwannu]

Exact-head source re-review at e4387ea001c4651b212357c0116bfa53bd4ef7e6 found no independent P0–P2 defect, and the feature is not superseded. HOLD only: the branch is 244 commits behind and now genuinely conflicts with merged #6106 in ProviderAuthPanel.tsx, account types, and related pool fields; preserve #6106 pause/pausing mutation guards while resolving. The PR remains draft/dirty with readiness 0/4, unsponsored OAuth surface, and no exact-head unit/typecheck matrix. Rebase, resolve those conflicts, complete sponsorship/checklist, and request fresh exact-head CI before approval. Nonblocking edge: an onboarding throw after observing explicit unknown paidTier can leave the prior display badge, but this is below P2.
