补齐 Codex 订阅请求的 account_id 参数,导出订阅日期;Grafana 仅显示节点与结束时间,并修复单节点筛选。关联 #623、#836。

日期选择由 Codex 生成临时 SubscriptionObservation,共享指标层不新增 ProviderId 分支。实时结果优先,成功空响应禁止回退;历史周期与确认到期分开。观测不序列化,不改凭据、不增请求;原指标和认证保持。完整说明见 docs/prometheus/README.zh-CN.md。

验证:旧实现的回归用例预期失败,修复后通过;99 项订阅测试和 69 项指标、路由、模型测试通过,格式与分支边界检查通过。

限制:严格 clippy 被基线已有 Grok/JetBrains 两处 nonminimal_bool 阻塞。本机用 Rust 1.96.1;1.98.0 安装缺 manifest。完整桌面门禁、Tauri 测试/clippy 和在线 Grafana 未验证。

Walkthrough

The change adds Codex subscription-date observations from the subscription API and validated credential periods, exports available dates as Prometheus metrics, and adds a Grafana subscription table. It also updates dashboard query interpolation, tests, and Prometheus documentation.

Changes: Codex subscription dates

Layer / File(s) Summary
Credential period parsing and enrichment
rust/src/core/*, rust/src/codex_accounts/subscription.rs, rust/src/providers/codex/*
OAuth credentials derive subscription periods from account-matched ID-token claims. Subscription enrichment uses API metadata when available and falls back to the credential period when the API is unavailable.
Subscription date metrics
rust/src/cli/serve/metrics/*
Provider metric snapshots capture observed subscription dates and their source. The renderer exports available timestamps and source flags. Tests cover date precedence, missing values, and failed fetches.
Dashboard and Prometheus documentation
docs/grafana/*, docs/prometheus/*
The dashboard adds a subscription information table and uses default variable interpolation in queries. Dashboard tests cover interpolation and panel configuration. Prometheus documentation describes the metrics and /metrics endpoint.

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

Full details: Provider Data Stays Siloed

Explanation

The PR adds no specific ProviderId branches in shared code and does not show a cross-account or cross-provider identity leak. Codex prepares subscription observations in its provider code. Credential-period fallback requires a matching account ID. Prior failure addressed: Commit 05e1ba9 removes the subscription-specific ProviderId::Codex branches from metrics/snapshot.rs. It moves date projection to providers/codex/subscription.rs and passes a generic observation to shared metrics code.

Full details: Secrets Handled Safely

Explanation

The change logs only timeout status and HTTP status. It extracts dates from the ID token without logging or persisting the token. The added test credentials are synthetic. The diff does not delete or overwrite credential files or keyring entries.

Full details: Ui Changes Include Windows Proof

Explanation

The PR adds a visible Grafana subscription table. The description reports a Windows CLI build and a passing isolated smoke test as the Windows proof note. It also states that online Grafana acceptance was not performed.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Translate the new metric bullets to English to match the rest of docs/CLI.md.

The rest of this file is in English. Line 331 labels the Prometheus examples page "(in Chinese)", so readers expect the Chinese content only in that page. The three new bullets are in Chinese. They sit between English bullets in the same list.

Write these bullets in English. Keep the metric names, startsAt, expiresAt and renewsAt unchanged. Leave the detailed Chinese description in docs/prometheus/README.zh-CN.md.
