Summary

ocx login <provider> in its default mode had no handler around the provider login, so a failed token exchange escaped to Bun's unhandled-error printer and wrote the provider's raw response text (and a stack trace) to stderr. Failed default-mode OAuth logins now print one fixed line and exit 1:

❌ OAuth login failed (HTTP 400 invalid_grant): OAuth authentication failed. Check the OpenCodex account status and retry.

The reason in parentheses is built only from fixed values: a validated HTTP status, the provider's OAuth error code when it is one of the standard RFC 6749/6750/8628 codes, network_error / timeout when the token endpoint could not be reached, configuration_error for a local setting that blocks the login, or oauth_authentication_failed. The message after the colon comes from the existing public OAuth vocabulary (publicOAuthAuthenticationErrorMessage).

A provider name that collides with a configured Codex account namespace is a local configuration problem. runLogin now raises it as a typed, fixed-text OAuthProviderNamespaceCollisionError that the public vocabulary admits. The terminal therefore still prints provider name must not collide with a configured Codex account namespace (which tests/cli/cli-provider.test.ts asserts) and does not fall back to the generic message. The dashboard login route reports the same fixed text.

Pool 2 preflight now checks raw config ownership at the shared CLI entry point before tolerant loading or prompting. Its known custom-row collisions and config read/parse failures use configuration_error. Status-less xAI token request wrappers use network_error without printing their cause.

Docs: CLI reference (providers-accounts.md), the runtime contract in structure/runtime.md, and the Anthropic account-pool contract.

Compatible with #7170 (252db6821d): merges cleanly in either order; its --headless handler keeps its own reporter.

Verification

Round 2 exact head: c0da7fdf17db880da131bb004b3e8d9235fe7d82.
All local test/check commands used OPENCODEX_HOME=$(mktemp -d) CODEX_HOME=$(mktemp -d); test listeners used ephemeral ports. The user's real settings were not used.

  • Red-to-green regressions in tests/oauth/oauth-login-cli-errors.test.ts: the new unreachable xAI endpoint case failed before its fix (9 pass / 1 fail); the custom anthropic2 row, malformed JSON, and unreadable config cases failed before their fix (10 pass / 3 fail). All 13 now pass as part of the final OAuth run. Each preflight case asserts exit 1, exactly one fixed configuration_error line, no stack/provider marker, and no prompt/browser/login start. Independent real bun run src/cli/index.ts login anthropic2 subprocess checks also passed for all three config fixtures.
  • bun test tests/oauth tests/cli/cli-provider.test.ts: 934 pass / 1 skip / 0 fail, 47 files. The skipped launcher test is platform-specific.
  • bun run typecheck: exit 0. bun run privacy:scan: passed. bun run structure:check: passed.
  • bun test tests/ci-workflows/file-size-ratchet.test.ts tests/test-layout.test.ts tests/test-layout-tooling.test.ts tests/ci-workflows/structure-ssot.test.ts: 87 pass / 0 fail.
  • (cd docs-site && bun install --frozen-lockfile && bun run build): exit 0; 577 pages built and 81,200 internal links checked.
  • feat(oauth): code-display login mode for hosts with no reachable localhost (carry #6239) #7170 compatibility (252db6821d176d61d1a1290182edfd85c672649a): git merge-tree --write-tree HEAD pr-7170 and git merge-tree --write-tree pr-7170 HEAD both exit 0 and produce identical tree 2f41ade37bc04a650b0b8869e0184abb723312a0. A separate local worktree of that combined tree passed bun run typecheck and bun test tests/oauth/oauth-code-login.test.ts tests/oauth/oauth-login-cli-errors.test.ts tests/oauth/oauth-anthropic-instance-registration.test.ts tests/oauth/oauth-login-cli-browser-launch.test.ts tests/cli/cli-provider.test.ts: 156 pass / 0 fail.
  • Full bun run test and import-connected bun run test:changed were not repeated because concurrent backlog worktrees share the machine; local coverage includes all OAuth tests, CLI provider regressions, repository guards, and the combined headless-login checks. Full cross-platform coverage remains with CI.
  • Exact head also pushed to mirror branch ci/pr-7171. As requested for this fix round, ci.yml was re-dispatched on fix/oauth-cli-error-bodies: https://github.com/lidge-jun/opencodex/actions/runs/38723519295 — queued when inspected, not passing evidence. Superseded runs 38722235090, 38721730339, 38718770279, and 38718757525 are confirmed cancelled.

📝 Walkthrough

The OAuth CLI now checks Pool 2 configuration before prompting and reports failed logins with fixed diagnostic categories, a public authentication message, and exit status 1. Typed errors identify namespace collisions and Pool 2 configuration read failures. Tests and documentation cover these changes.

Changes: OAuth login diagnostics

Layer / File(s) Summary
Typed configuration errors and diagnostic mapping
src/oauth/index.ts, src/oauth/store-anthropic-instance.ts, src/oauth/login-cli-errors.ts
Namespace collisions and Pool 2 configuration read failures now use typed errors. The diagnostic function validates HTTP statuses and recognized OAuth error codes, then classifies other errors as timeout, network, or authentication failures.
CLI reporting and regression coverage
src/oauth/login-cli.ts, tests/oauth/oauth-login-cli-errors.test.ts, scripts/test-layout/layout.json, tests/fixtures/test-layout-expected.json
The CLI checks Pool 2 ownership before provider dispatch and sends login rejections to the reporter. Tests cover provider failures, non-Error rejections, namespace collisions, and Pool 2 preflight errors. The test is mapped to the OAuth shard.
CLI diagnostic documentation
docs-site/src/content/docs/reference/cli/providers-accounts.md, structure/providers/anthropic-account-pool.md, structure/runtime.md
The documentation describes the login diagnostics, Pool 2 preflight checks, and public error reporting.

…in failures

Print an allowlisted RFC 6749/8628 error code next to the HTTP status,
label unreachable or timed-out token endpoints, and report a Codex
account namespace collision before the login starts instead of as a
generic authentication failure.
The default ocx login path now prints only the public OAuth vocabulary,
so the plain Error thrown for a provider name that collides with a Codex
account namespace read as a generic authentication failure and broke
cli-provider's login collision test. Throw a typed fixed-text error that
the public message allowlist admits and label it configuration_error.
