+Cette option regroupe des comptes OAuth Google Antigravity uniquement pour le fournisseur Cloud Code

+Google AI Studio, Vertex AI, une autre entrée de fournisseur ou une route utilisant une clé API.

+| `googleAntigravityAccountPool.enabled?` | `boolean` | `false` | Active l'affinité de session locale au processus et un basculement borné après une réponse finale 429 ou une réponse 402 remontée. |
+| `googleAntigravityAccountPool.autoSwitchThreshold?` | `number` | `80` | Seuil d'épuisement de 0 à 100. `quota` et `fill-first` utilisent l'utilisation maximale en cache correspondant à la famille `Gem` ou `Cla` du modèle demandé ; une utilisation inconnue conserve le compte actif sain. `0` désactive le changement selon l'utilisation, pas la reprise après échec. |
+| `googleAntigravityAccountPool.strategy?` | `"quota" \| "round-robin" \| "fill-first"` | `"quota"` | Stratégie pour les sessions nouvelles ou sans liaison. |
+| `googleAntigravityAccountPool.stickyLimit?` | `number` | `1` | Nombre de liaisons de nouvelles sessions conservées sur une sélection `round-robin`. Plage 1–100 ; sans effet sur les autres stratégies. |
+
+Les stratégies conservent l'affinité d'une session tant que son compte reste admissible. Pour une
+session nouvelle ou sans liaison, `quota` conserve le compte actif sain lorsque l'utilisation pertinente
+est inconnue ou inférieure au seuil, puis choisit le compte admissible dont l'utilisation connue est la
+plus faible. `round-robin` répartit uniformément les liaisons et n'emploie pas le seuil pour la rotation
+ordinaire. `fill-first` remplit le compte actif jusqu'à sa temporisation, son indisponibilité ou le seuil
+d'épuisement, puis passe au compte admissible suivant.
+
+Chaque envoi résout un instantané OAuth lié à cette génération, avec le jeton bearer et le `projectId`
+Cloud Code Assist. Une réponse finale 429 ou une réponse 402 remontée met le compte en temporisation,
+efface son affinité et reconstruit la requête pour un autre instantané admissible. Sans `Retry-After`
+exploitable, la temporisation par défaut est de 60 secondes ; une valeur amont analysée est plafonnée à
+15 minutes. Une requête autorise au plus trois basculements, soit quatre envois amont au total. Si tous
+les comptes admissibles sont en temporisation, le client reçoit un 429 avec le premier `Retry-After`
+connu.
+
+:::caution[Résilience opérationnelle, pas contournement de quota]
+Utilisez ce pool pour récupérer après des défaillances transitoires, pas pour contourner les quotas ou
+les contrôles du fournisseur. L'automatisation multicomptes peut enfreindre les conditions du fournisseur ;
+laissez cette fonction désactivée si vous n'acceptez pas ce risque.

+### `googleAntigravityAccountPool`（実験的）
+
+このオプトイン機能は、`google-antigravity` Cloud Code Assist プロバイダー専用に Google
+Antigravity OAuth アカウントをプールします。デフォルトでは無効です。このプールの認証情報が
+Google AI Studio、Vertex AI、別のプロバイダー項目、API キールートに使われることはありません。
+
+| キー | 型 | デフォルト | 説明 |
+| --- | --- | --- | --- |
+| `googleAntigravityAccountPool.enabled?` | `boolean` | `false` | プロセスローカルなセッション親和性と、最終的な 429 または表面化した 402 に対する回数制限付きフェイルオーバーを有効にします。 |
+| `googleAntigravityAccountPool.autoSwitchThreshold?` | `number` | `80` | 0～100 の使用量消化しきい値です。`quota` と `fill-first` は、要求モデルの `Gem` または `Cla` ファミリーに関係するキャッシュ済み使用量の最大値を使います。使用量が不明なら正常なアクティブアカウントを維持します。`0` は使用量による切り替えだけを無効にし、障害回復は無効にしません。 |
+| `googleAntigravityAccountPool.strategy?` | `"quota" \| "round-robin" \| "fill-first"` | `"quota"` | 新規セッションまたは未バインドのセッションに使う戦略です。 |
+| `googleAntigravityAccountPool.stickyLimit?` | `number` | `1` | 1 回の `round-robin` 選択に維持する新規セッションのバインド数です。範囲は 1～100 で、ほかの戦略には影響しません。 |
+
+どの戦略でも、対象アカウントが適格である間は既存のセッション親和性を維持します。新規または
+未バインドのセッションでは、`quota` は関連使用量が不明またはしきい値未満なら正常なアクティブ
+アカウントを維持し、その後は既知使用量が最小の適格アカウントを選びます。`round-robin` は
+バインドを均等に分配し、通常のローテーションにはしきい値を使いません。`fill-first` はクールダウン、
+利用不能、消化しきい値のいずれかに達するまでアクティブアカウントを使い、その後で次の適格
+アカウントへ進みます。
+
+各送信では、bearer token と Cloud Code Assist の `projectId` を含む、世代に固定された OAuth
+スナップショットを 1 つ解決します。最終的な 429 または表面化した 402 を受けると、そのアカウントを
+クールダウンし、親和性を解除して、別の適格なスナップショットでリクエストを再構築します。有効な
+`Retry-After` がなければ既定のクールダウンは 60 秒で、解析できた上流値は 15 分を上限とします。
+1 リクエストにつきフェイルオーバーは最大 3 回、上流への送信は合計最大 4 回です。すべての適格
+アカウントがクールダウン中なら、クライアントには最も早い既知の `Retry-After` を付けて 429 を返します。
+
+:::caution[運用上の回復力であり、クォータ回避ではありません]
+このプールは一時的なアカウント障害からの回復に使い、クォータやプロバイダーの制限を回避するために
+使わないでください。複数アカウントの自動運用は利用規約に違反する可能性があります。そのリスクを
+受け入れない場合は無効のままにしてください。

+
+This opt-in pools Google Antigravity OAuth accounts for the `google-antigravity` Cloud Code Assist
+provider only. It is disabled by default. The pool never supplies credentials to Google AI Studio,
+Vertex AI, another provider entry, or an API-key route.
+
+| Key | Type | Default | Description |
+| --- | --- | --- | --- |
+| `googleAntigravityAccountPool.enabled?` | `boolean` | `false` | Enable process-local session affinity and bounded failover on a final 429 or surfaced 402 response. |
+| `googleAntigravityAccountPool.autoSwitchThreshold?` | `number` | `80` | Usage drain threshold from 0–100. `quota` and `fill-first` use the maximum cached usage relevant to the request model's `Gem` or `Cla` family; unknown usage keeps a healthy active account. `0` disables usage-driven switching, not failure recovery. |
+| `googleAntigravityAccountPool.strategy?` | `"quota" \| "round-robin" \| "fill-first"` | `"quota"` | Strategy for new or otherwise unbound sessions. |
+| `googleAntigravityAccountPool.stickyLimit?` | `number` | `1` | New-session binds retained on one `round-robin` selection. Range 1–100; it does not affect the other strategies. |
+
+The strategies preserve an eligible session affinity once it exists. For a new or unbound session,
+`quota` keeps the healthy active account while its relevant usage is unknown or below the threshold,
+then selects the eligible account with the lowest known usage. `round-robin` distributes binds evenly
+and does not use the threshold for ordinary rotation. `fill-first` keeps filling the active account
+until cooldown, unavailability, or the drain threshold, then advances to the next eligible account.
+
+Each dispatch resolves one generation-bound OAuth snapshot containing both the bearer token and Cloud
+Code Assist `projectId`. A final 429 or surfaced 402 cools the failed account, clears its affinity, and
+rebuilds the request for another eligible snapshot. The default cooldown is 60 seconds when no usable
+`Retry-After` is present; a parsed upstream value is capped at 15 minutes. One request permits at most
+three failovers (four total upstream dispatches). If every eligible account is cooling, the client
+receives 429 with the earliest known `Retry-After`.
+
+:::caution[Operational resilience, not quota bypass]
+Use this pool to recover from transient account failures, not to evade quotas or provider enforcement.
+Multi-account automation can violate provider terms; keep the feature disabled unless you accept that
+risk.

+values. Success returns top-level `{ ok: true, provider, enabled, autoSwitchThreshold, strategy,

+### `googleAntigravityAccountPool` (экспериментальная функция)
+
+Эта opt-in функция объединяет Google Antigravity OAuth-аккаунты только для Cloud Code Assist
+провайдера `google-antigravity`. По умолчанию она выключена. Пул никогда не передаёт credentials в
+Google AI Studio, Vertex AI, другую запись провайдера или маршрут с API-ключом.
+
+| Ключ | Тип | По умолчанию | Описание |
+| --- | --- | --- | --- |
+| `googleAntigravityAccountPool.enabled?` | `boolean` | `false` | Включить локальную для процесса привязку сессий и ограниченный failover после финального 429 или дошедшего до прокси 402. |
+| `googleAntigravityAccountPool.autoSwitchThreshold?` | `number` | `80` | Порог расходования от 0 до 100. `quota` и `fill-first` берут максимальное cached usage, относящееся к семейству `Gem` или `Cla` запрошенной модели; при неизвестном usage сохраняется здоровый активный аккаунт. `0` отключает переключение по usage, но не восстановление после сбоев. |
+| `googleAntigravityAccountPool.strategy?` | `"quota" \| "round-robin" \| "fill-first"` | `"quota"` | Стратегия для новых или ещё не привязанных сессий. |
+| `googleAntigravityAccountPool.stickyLimit?` | `number` | `1` | Число привязок новых сессий, удерживаемых на одном выборе `round-robin`. Диапазон 1–100; на другие стратегии не влияет. |
+
+Все стратегии сохраняют существующую привязку сессии, пока аккаунт остаётся подходящим. Для новой
+или непривязанной сессии `quota` сохраняет здоровый активный аккаунт, пока относящееся к модели usage
+неизвестно или ниже порога, а затем выбирает подходящий аккаунт с наименьшим известным usage.
+`round-robin` равномерно распределяет привязки и не использует порог при обычной ротации. `fill-first`
+заполняет активный аккаунт до cooldown, недоступности или порога расходования, затем переходит к
+следующему подходящему аккаунту.
+
+Для каждого dispatch разрешается один привязанный к поколению OAuth snapshot, содержащий bearer token
+и Cloud Code Assist `projectId`. Финальный 429 или дошедший до прокси 402 переводит сбойный аккаунт в
+cooldown, очищает его привязку и пересобирает запрос для следующего подходящего snapshot. Если пригодного
+`Retry-After` нет, cooldown по умолчанию равен 60 секундам; распознанное значение upstream ограничено
+15 минутами. Один запрос допускает не более трёх failover, то есть всего четырёх upstream dispatch.
+Если все подходящие аккаунты в cooldown, клиент получает 429 с самым ранним известным `Retry-After`.
+
+:::caution[Операционная устойчивость, а не обход квот]
+Используйте пул для восстановления после временных сбоев аккаунта, а не для обхода квот или enforcement
+провайдера. Автоматизация нескольких аккаунтов может нарушать условия провайдера; оставьте функцию
+выключенной, если вы не принимаете этот риск.

+| `googleAntigravityAccountPool.autoSwitchThreshold?` | `number` | `80` | 0–100 的用量耗盡閾值。`quota` 與 `fill-first` 使用和請求模型 `Gem` 或 `Cla` 家族相關的最高快取用量；用量未知時保留健康的現用帳號。`0` 只停用依用量切換，不停用故障復原。 |
+| `googleAntigravityAccountPool.strategy?` | `"quota" \| "round-robin" \| "fill-first"` | `"quota"` | 新 session 或未綁定 session 的策略。 |
+| `googleAntigravityAccountPool.stickyLimit?` | `number` | `1` | 一次 `round-robin` 選擇所保留的新 session 綁定數。範圍 1–100；不影響其他策略。 |
+
+只要帳號仍合格，所有策略都會保留既有 session 親和性。對於新 session 或未綁定 session，
+`quota` 會在相關用量未知或低於閾值時保留健康的現用帳號，之後選擇已知用量最低的合格帳號。
+`round-robin` 平均分配綁定，正常輪換不使用該閾值。`fill-first` 會持續使用現用帳號，直到帳號
+進入冷卻、不可用或到達耗盡閾值，再前進到下一個合格帳號。
+
+每次派送都會解析一份綁定到該代請求的 OAuth 快照，其中同時包含 bearer token 與 Cloud Code
+Assist `projectId`。最終 429 或傳到此處的 402 會讓失敗帳號進入冷卻、清除其親和性，並用另一份
+合格快照重建請求。若沒有可用的 `Retry-After`，預設冷卻 60 秒；成功解析的上游值最高限制為
+15 分鐘。單一請求最多允許 3 次容錯移轉，也就是總計 4 次上游派送。若所有合格帳號都在冷卻，
+客戶端會收到 429，並附上已知最早的 `Retry-After`。
+
+:::caution[用於營運韌性，而非繞過配額]
+請只用此池從暫時性帳號故障中復原，不要用來規避配額或供應商管控。多帳號自動化可能違反供應商
+條款；若不接受這項風險，請保持停用。
