Problem

A Codex instance behind a custom model provider (requires_openai_auth = false, for example a CLIProxyAPI hub) needs no ChatGPT login. Without one, Codex refuses account/rateLimits/read with -32600 "codex account authentication required to read rate limits", and Usage → Limits shows Codex could not read usage (JSON-RPC -32600). for every such instance (#11873).

If the login is removed while the T3 server runs, it is worse: a failed read keeps the last published limits and the old account ID, and turn notifications keep updating them. The instance stays a separate Codex column for an account it is no longer signed in to.

Change

When the usage read fails with Codex's "… authentication required to read rate limits" refusal, the instance reports its limits as unsupported, like an API-key account. As a result:

Limits shows no notice for it.
Its kept limits and account ID are dropped.
Later turn notifications are ignored.

Everything else is unchanged. A successful usage read still publishes limits, and any other failure still shows the notice.

Why not the open PRs

#33312 (reopened as the fix for #11873) treats account/read returning no account as "no limits" and skips the usage read. But Codex returns account: null for every custom-provider instance, signed in or not. A custom-provider instance with a saved ChatGPT login still gets valid limits from account/rateLimits/read (captured below). #33312 marks those instances unsupported too, so they lose:
- the limits in the thread details card and /usage-limits;
- the reset credit;
- the switch to a new thread when the weekly window runs out, because unsupported drops live updates (packages/provider-core/src/server/usageLimits.ts:56).
A maintainer asked it to preserve successful native usage reads when account/read returns no account, and its head has not changed since. This PR is that narrower rule: it reacts to Codex's own refusal, not to the empty account. If #33312 adopts the same rule, close this one.
#18622 publishes native limits only when config/read confirms a native OpenAI endpoint, by design, for the quota-attribution problem in #11515. That also removes this notice. But it hides limits for every custom route, including the signed-in case above, and decides by parsing URLs from the Codex config. This PR takes no position on attribution.
#27555, #28882 and #25784 (#23054) merge native reports into the hub's account by account ID or email. They do not touch an instance with no login. They complement this change, because merging by account ID is only sound once a signed-out instance stops publishing under its old ID.

Scope and approval

Fixes #11873. This is the narrower refusal rule requested on #33312 (comment). The change is server-side and Codex-only. It does not change the matcher or any client.

Verification

Live Codex. codex-cli 0.167.0 with a custom provider and requires_openai_auth = false, one config, two homes:

text

1	no saved login
2	account/read -> {"account":null,"requiresOpenaiAuth":false}
3	account/rateLimits/read -> -32600 "codex account authentication required to read rate limits"
4
5	saved ChatGPT login
6	account/read -> {"account":null,"requiresOpenaiAuth":false}
7	account/rateLimits/read -> rateLimits + accountId, same weekly numbers the hub reports

The second pair is why account: null alone cannot mean "no limits".

Four machines. A build of this branch ran on two Linux machines, one macOS and one Windows. All four route Codex through one CLIProxyAPI hub that holds one ChatGPT account, and one of them has the hub as a usage source.

Before (T3 0.1.7, same code path as main): five Codex columns for one account, one per environment plus the hub's. Three machines still had an old ChatGPT login. The fourth had its login removed while the server ran, so it kept its old column.
With this branch: the signed-out machine reported no limits. The three with an old login kept their columns, because their usage read still succeeds. That is the signed-in case this PR deliberately leaves alone.
After codex logout on those three: every probe hits the refusal, and Limits shows one Codex entry, the hub's account with its reset credit. There is no notice.

Before	After
Before: five Codex columns for one account	After: one Codex entry

Tests.

codexUsageLimits.test.ts covers which errors count as a missing login: both refusal messages count; a -32603 401 does not.
In ProviderRegistry.test.ts, the existing "does not require OpenAI auth" case now feeds the refusal and asserts unsupported. On main the same refusal gives probeFailed and the notice.
vp test run on both files: 70 passed. vp run check:changed passes: format, lint, knip, typecheck (41 packages) and tests.

Not checked. Other Codex versions and the keyring credential store. The refusal is matched on its message suffix, so if Codex rewords it, the notice comes back as it is today; nothing gets hidden.

Merge risk

Only refused reads change. Signed-in instances, API-key accounts and other failures behave as before.
A rejected login still shows the notice. When the backend rejects a saved login (-32603, 401 invalid_jwt, reported on #33312), the notice stays on purpose. On a custom provider that login is a stale leftover, and codex logout turns it into the case handled here. On the default provider it is an expired login the user should see.
A default-provider instance with no login also loses the usage notice. Its provider status still says Codex CLI is not authenticated. Run codex login.
A signed-out instance loses the new-thread switch. It no longer takes limit windows from turn notifications, so it misses the switch when the weekly window runs out. On main it got that from those notifications.

Approvability

Verdict: Approved at 8db86d1

Macroscope's review found this PR approvable — Codex usage reporting now treats a missing ChatGPT login as unsupported rather than a probe failure. This narrowly scoped metadata change preserves authentication behavior and does not change actual usage limits or enforcement.

Walkthrough

The Codex provider now recognizes a specific missing-login rate-limit error and reports usage limits as unsupported. Other rate-limit failures remain probe failures, and successful rate-limit data is converted as before.

Changes: Codex usage-limit classification

Layer / File(s)	Summary
Recognize missing-login errors `apps/server/src/provider/codexUsageLimits.ts`, `apps/server/src/provider/codexUsageLimits.test.ts`	An exported predicate identifies the specified `-32600` authentication-required error. Tests distinguish it from other errors.
Classify provider usage limits `apps/server/src/provider/CodexProvider.ts`, `apps/server/src/provider/ProviderRegistry.test.ts`	The rate-limit probe records recognized missing-login errors. Usage limits map API-key accounts and missing-login results to `unsupported`; absent or failed data maps to `probeFailed`. The provider status test checks the unsupported result.

After an external login, limits may remain hidden until a full refresh. The dashboard refresh provides a workaround, so the change is mergeable with this limitation.

Explanation

[#11873] The reviewed implementation maps Codex’s specific authentication-required rate-limits refusal to unsupported. The prior review established that this clears published limits and ignores later turn updates. Successful usage reads and other failures retain their existing behavior. The current test covers the target refusal and rejects an unrelated -32600 error and a -32603 failure.

Test an unrelated -32600 error.
The current negative case checks a different code, but not a different message with code -32600. If the suffix check is removed, an unrelated -32600 failure would become unsupported and lose its failure notice. Add that negative case to this test.

Test the refusal through the Codex probe.

Use a fake app server that returns no account and rejects account/rateLimits/read with the matching -32600 message. Assert that the status reports unsupported. The matcher and injected-status tests can pass if the probe classifies that refusal as a failure.

Not adding this one. The two pieces the probe joins are each tested: isCodexUsageLoginMissing classifies Codex's refusal (codexUsageLimits.test.ts), and this case checks that a refused read becomes unsupported. The probe line between them is a one-line ternary that calls that classifier, which docs/internals/testing.md asks us to leave untested as wiring. A fake app-server subprocess would test the same behaviour a third time.

The nitpick in the review summary was real, though: an unrelated -32600 is now a negative case in edfa60c4a5.

@nuuls You’re right. The classifier and status mapping have focused tests, and the probe connects them with a direct conditional. I’ll withdraw the request for a subprocess test.

Thanks for adding the unrelated -32600 negative case.
