fix(codex): warm up new ChatGPT Free accounts instead of blaming the credential (#4126) - #4230
Conversation
…credential A ChatGPT account created today has no gpt-5.4-mini and no gpt-5.5, so warmup took a 404 on the default model, found nothing retryable, and told the operator to reauthenticate a login that had just succeeded. gpt-5.6-luna is provisioned on Free and runs in official Codex clients, so it joins FALLBACK_MODELS, and 404 joins 400 as a retryable warmup status behind one shared predicate. The fallback loop now stops on a non-retryable retry error rather than walking the rest of the list, which keeps a mid-chain 401 from being overwritten by a later 404. verifyCodexAccountWarmup no longer claims reauthentication is required when every model was refused for a provisioning reason. It picks its message from isCodexWarmupProvisioningFailure(), which reuses the retry predicate, so widening the retryable set can never leave the operator-facing message disagreeing with the policy that produced the error. The HTTP status stays 401: its only consumer is the OAuth login-state wrapper, which reads the JSON body and ignores the status.

This commit identifies PR #4188 as carried work, but commit 24a1040 contains no Co-authored-by trailer, and the cited branch commit 7f91737c2 is not its ancestor, so GitHub will not credit chilung-cgu after the squash.

When all fallback attempts end in 400/404, this changes the operator-visible OAuth login-state error, but the added tests exercise only warmCodexAccount and the standalone classifier; none invokes the auth flow and asserts that the provisioning message, rather than the reauthentication message, reaches login state. Add a focused case in codex-auth-api.test.ts for the 404/400 exhaustion path (and retain a 401 comparison) so this user-facing branch cannot silently regress.

Document the warmup failure distinction in the canonical guide and both translations.
verifyCodexAccountWarmup exposes http_status:401/http_status:403 as reauthentication failures, while exhausted http_status:400/http_status:404 fallback attempts require model-access or provisioning checks. Add this mapping to docs-site/src/content/docs/guides/codex-integration.md#L707-L715, then mirror it in docs-site/src/content/docs/fr/guides/codex-integration.md#L376-L382 and docs-site/src/content/docs/zh-tw/guides/codex-integration.md#L320-L326. Without it, the reachable account-add and reauthentication workflow does not tell operators which recovery action applies.

Add endpoint assertions for both warmup failure messages.
handleCodexAuthAPI reaches verifyCodexAccountWarmup while polling /api/codex-auth/login. The existing tests drive this path, but failure coverage only checks generic status and error properties. Add cases in tests/codex-integration/codex-auth-api.test.ts that assert the provisioning message for exhausted 400/404 fallbacks and the reauthentication message for 401/403 responses.

The fallback loop now stops on a non-retryable retry error instead of walking the rest of the list, so a mid-chain 401 is no longer overwritten by a later 404 —src/oauth/token-guardian.ts:264persists that reason andsrc/codex/quota-auto-refresh.ts:180branches on it.verifyCodexAccountWarmupno longer claims reauthentication is required when every model was refused for a provisioning reason.

This is theauth-api.tshalf that fix(codex): retry warmup with gpt-5.6-luna on 400 and 404 for ChatGPT Free accounts (#4126) #4188's description promised and its diff did not contain, and it is what the issue asks for directly: separate a 401/403 credential failure from a 404 provisioning failure.src/codex/auth-api.ts:2845, which reads the JSON body and ignores the status, so moving it would have been an unrelated contract change with no caller asking for it.docs-site/src/content/docs/guides/codex-integration.mdand its seven locale copies.Carries PR #4188 by @chilung-cgu, which was an open draft reset by the readiness gate rather than rejected.

Hosted CI on the exact pushed head is the only product evidence this change is offered on.xai/grok-4.6subagent reviewed the staged diff adversarially before push and returned pass: no caller depended on exhausting every fallback; a repeating 404 is bounded at 3 upstream POSTs per call behindquota-auto-refresh's 5-minute retry floor andtoken-guardian's 300s–3600s backoff;isCodexWarmupProvisioningFailure(new CodexWarmupError("http_status"))correctly returnsfalse; and no existing test asserts the old message, the 401 on that response, or a one-entryFALLBACK_MODELS.Checklist
Warmup touches an authentication path, so it was read for that specifically. Nothing new is logged: upstream error bodies still go through the bounded
