What Changed

When Codex's account/read names no account, the Codex status probe now reads the email claim from the ChatGPT login stored in $CODEX_HOME/auth.json. It checks the configured home, then CODEX_HOME, then ~/.codex. The email goes on auth.email only; auth status stays unknown, and nothing else in the file is used. Missing or malformed files are ignored.

Why

When Codex is routed through a CLIProxyAPI pool, it uses a custom model_provider with requires_openai_auth = false. In that mode, account/read returns account: null. account/rateLimits/read still answers, though, for the ChatGPT login in auth.json. The native Codex instance therefore publishes that account's windows with no email.

The Limits view matches accounts by driver:email (collectLimitAccounts). Without an email, it can't tell that those windows belong to an account the CLIProxyAPI usage source also reports. The account then shows up twice: one bar named "Codex" and one for the hub copy, with identical usage and reset times. Both bars also count toward the pooled percentage.

This is the missing-email case left open by #10700 ("Instances without an email remain separate") and the duplicate described in #11515.

Verified against a real setup: with a codex-t3 wrapper that routes through CLIProxyAPI, the probe previously reported no email. With this change, it reports the stored login's email, which matches the hub account.

Checklist

  • This PR is small and focused
  • I explained what changed and why
  • I included before/after screenshots for any UI changes (n/a: no UI code changes; the duplicate bar merges into one)
  • I included a video for animation/interaction changes (n/a)

Checks run locally: CodexProvider.test.ts + ProviderRegistry.test.ts (61 passed, including the new tests), tsc --noEmit for apps/server, vp lint, vp fmt.

Summary by CodeRabbit

  • Bug Fixes
    • Improved Codex account status detection when live account details are unavailable.
    • The stored ChatGPT login email is now used as a fallback for authentication details.
    • Invalid, incomplete, or unreadable stored login data no longer causes authentication checks to fail.
    • Authentication status remains accurately reported as unknown when no account is available, while preserving any stored login email.

…s the account

A custom model_provider with requires_openai_auth = false (a CLIProxyAPI
pool) makes account/read report no account, while account/rateLimits/read
still answers for the ChatGPT login in auth.json. With no email, Limits
cannot merge those windows with the same account a usage-limit source
reports, and shows it twice. Read the email claim from the stored login.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — The production change reads a user's Codex authentication file and exposes its stored login email through provider status, also affecting usage-limit account merging. Despite its focused scope and tests, this authentication and sensitive-data surface warrants human review.

Codex login fallback

Layer / File(s) Summary
Stored login email extraction
apps/server/src/provider/Layers/CodexProvider.ts, apps/server/src/provider/Layers/CodexProvider.test.ts
The provider reads auth.json, decodes the stored login id_token, and extracts a non-empty email claim. Tests cover invalid JSON, missing tokens, and missing payloads.
Probe and status fallback
apps/server/src/provider/Layers/CodexProvider.ts, apps/server/src/provider/Layers/ProviderRegistry.test.ts
When account/read has no account, the probe adds the stored email to its snapshot. Account status uses that email while preserving a live account email when available. Tests verify the resulting status and email.

Reject JWT values with an invalid segment count.

A two-segment id_token with a decodable payload passes idToken.split(".")[1] and returns its email. When account/read reports no account, accountProbeStatus uses that email as auth.email. Ignore malformed stored-login data by requiring exactly three JWT segments.

Suggested fix
-    const payload = typeof idToken === "string" ? idToken.split(".")[1] : undefined;
+    const parts = typeof idToken === "string" ? idToken.split(".") : [];
+    const payload = parts.length === 3 ? parts[1] : undefined;

Add a test with a two-segment token whose payload contains an email claim.

Independent confirmation from a second real setup, tested at ac6bf4acef.

Setup: one CLIProxyAPI 7.3.18 hub with three Codex OAuth accounts, added under Usage providers. Two Linux servers each keep a ChatGPT login in ~/.codex/auth.json (for Remote Control identity), while model_provider = "cliproxyapi" routes model traffic through the hub. That login is also one of the hub's pooled accounts.

Before: Limits draws the same subscription once per environment plus once via the hub, with identical percentages and resets:

Codex limits duplicated

On the server, codex app-server (0.157.1) returns account/read → { account: null, requiresOpenaiAuth: false }. account/rateLimits/read still answers for the stored login (it includes accountId and planType: plus).

With this PR: I ran the real checkCodexProviderStatus against the server's own Codex home (live probe, not a fixture):

auth
main { status: "unknown" }
#13114 { status: "unknown", email: "info@drumo.cz" }

The email matches the hub's auth file for that account, so accountKey("codex", email) now merges the native and hub rows into one. CodexProvider.test.ts and ProviderRegistry.test.ts pass (61/61).

Related: #11515, #10701/#10700 (the missing-email case they leave open), and the closed #10877 (the alternative "omit native quota" approach). I understand provider-layer changes are on hold for V2 (#10877). If this lands there instead, the same auth.json email fallback (or dropping native quota for requiresOpenaiAuth: false) fixes this setup.

Since this PR already decodes the stored Codex ID token, I think it's worth preserving the stable workspace identity alongside the email instead of discarding it.

CLIProxy auth files already expose id_token.chatgpt_account_id, and that is exactly the discriminator missing in #10835: one email can have Personal + Business, or two Business workspaces with the same plan label.

Could the parser return both claims:

{
  email,
  accountId: chatgpt_account_id,
}

and carry the id on provider auth as an optional stable logical account identity?

Email remains useful for display/native-hub matching fallback, but chatgpt_account_id is the stronger key when present. This would also let #10845 stop relying on plan labels for the cases where Codex already gives us a real workspace identity.

I would keep this optional so old Codex/auth shapes retain today's fallback behavior.
