fix(devin): route a revoked key to needsReauth and follow CLI key rotation

[wtfsayo]

Summary

Two Devin credential defects, both reproduced against a live account.

A revoked or invalid Devin key never reached needsReauth.

• Live, a bad key gets 401 unauthenticated. refreshDevinToken throws invalid_grant so that a forced refresh can flag the account, but nothing ever forced one:
  • The OAuth 401 replay lived only in adapter-dispatch.ts, the HTTP-response path. Devin is a runTurn adapter, and the runTurn path had no 401 handling at all.
  • devin was missing from both the replay list and FORCE_REFRESH_PROVIDERS.
  • The stored expiry never runs out. That part is correct: the session JWT carries only session_id, no exp.
• The result: a dead account looked healthy in the dashboard, every turn failed with 401, and a multi-account setup kept routing to it.

CLI-imported accounts never picked up a rotated key. A local-cli account copied credentials.toml once. After devin auth login rotated the key, opencodex kept the stale one forever.

What changed:

• runTurn 401 replay (src/server/responses/run-turn-execution.ts):

  • When a turn's first output is an error with a structured 401 status, the adapter runs the same forced refresh the HTTP path uses, once per request, under an auth-recovery hop.
  • A successful refresh replays the turn. A terminal failure marks the account needsReauth and moves the turn to a surviving account, within genericFailoverLimit.
  • With no other account, the 401 surfaces as "Not logged in to devin. Run: ocx login devin".
  • It is gated on the replay list, authMode === "oauth" and a held OAuth snapshot, and devin is the only runTurn provider on that list. It never fires after meaningful output has reached the client.
  • The account-rebind code from the existing 429 rotation is extracted into a shared adoptRunTurnAccount.

• Multi-account failover (src/oauth/kiro-terminal-failover.ts): Kiro's alternate-account helper is generalized into tryAlternateAfterTerminalRefresh, which counts every stored login, flagged ones included. The old helper only worked for Kiro and counted only healthy accounts, so once the dead account was flagged, a two-account setup looked like one. Both the runTurn and Kiro paths now try the alternate on any refresh failure. The helper still requires the sent generation to be flagged needsReauth, so a transient failure on a healthy account never fails over.

• CLI key rotation (src/oauth/devin.ts): for a local-cli account, refreshDevinToken re-reads the CLI credential file. It adopts the file's key only when all of these hold:

  • the key differs from the stored one;
  • the file's host passes the Devin api-server allowlist (checked before any request);
  • the key mints a user JWT through the existing GetUserJwt call. A session token carries no identity, so this is where the auth_uid and email come from, with a 5 s bound;
  • the minted identity does not contradict the account's stored one;
  • no other stored account owns the key or that identity.

  Only a definitive 401/403 from that mint, or a token without auth_uid, counts as a dead key. A timeout, network error, 5xx or 429 does not flag the account, so the next 401 retries. The shared credential merge now keeps local-cli when the refresh itself returns it, which also stops Meta Muse's local-cli accounts being relabelled oauth. The generic refresh lock passes the account id to provider refresh functions as an optional argument; only Devin reads it.

• By design: Cognition has no refresh endpoint, so a single upstream 401 on an oauth-source Devin account marks it needsReauth. This is recorded in structure/transports/responses-failover.md together with the identity rule.

• A 429, or a permission_denied carrying quota wording (already mapped to 429), is never treated as an auth failure.

Verification

Live end to end (isolated OPENCODEX_HOME, proxy from this branch, devin/swe-1-6; no keys printed, temp homes deleted):

Scenario	Result
ocx login devin via CLI credential import (no browser)	Stored as local-cli; a real turn returns "PONG"
Stored key corrupted, CLI file path pointed at a missing file	Account marked needsReauth: true; the turn fails with "Not logged in to devin. Run: ocx login devin" (authentication_error); the next request is an HTTP 401 with the same text; streaming shows it in response.failed
Stored key corrupted, OPENCODEX_DEVIN_CLI_CREDENTIALS pointed at a copy of the real credentials file	Turn succeeds ("PONG"); the stored key now matches the file, stays local-cli, no needsReauth, identity recorded from the real GetUserJwt

Tests

• New tests/responses/responses-devin-401-replay.test.ts (21 pass), registered in both layout files. It covers:
  • failover and needsReauth, streaming and buffered, with the dead account not reselected on the next request;
  • a lone dead account: the login instruction, and fast failure afterwards without resending the key;
  • a staged concurrent 401 after the first turn already failed over;
  • rotated, unchanged, missing and off-allowlist CLI files (the off-allowlist host never reaches the mint);
  • a key owned by another account, conflicting accountId or email, an identity owned elsewhere, and an id recorded from sub;
  • email case and whitespace;
  • 503, 429 and network mint failures (not flagged) versus 403 or a missing auth_uid (flagged);
  • a 429 not treated as auth.
• Most of these fail with the source changes stashed.
• bun test tests/responses/responses-devin-401-replay.test.ts tests/ci-workflows/file-size-ratchet.test.ts tests/test-layout.test.ts tests/test-layout-tooling.test.ts: 48 pass, 0 fail.
• Kiro, OAuth, Devin, Meta Muse, 401-recovery, file-size, structure and layout suites: 1650 pass, 1 fail. The one failure, tests/oauth/oauth-callback-server.test.ts "a non-callback request cannot pin the socket to the retiring flow", also fails on an untouched dev checkout.
• bun run typecheck, bun run structure:check and bun run privacy:scan pass.
• bun run test:changed on the first commit: 19 failures in service-install, config-PUT, Grok-toggle and socks5 tests, none importing this code. It ran while three sibling worktrees ran their own suites, and the spot-checked files passed 98/98 alone. The full suite was rerun afterwards on an idle machine; see the comparison below.

Review: two independent adversarial reviews (correctness and failure paths; security and requirements), then a third on the follow-up delta.

• Security review: no findings.
• Correctness review, fixed in a42f349c7:
  • a concurrent-request 401 could skip failover;
  • CLI key adoption failed open when identity was unknown;
  • the 401 alternate ignored genericFailoverLimit;
  • the shared local-cli merge rule was undocumented.
• Re-review of the delta, fixed in 40379257c:
  • a transient mint failure would permanently flag a working account;
  • sub/auth_uid and email comparisons were inconsistent;
  • a slow mint could hold the refresh lock for 30 s.

Known limit: a buffered (non-streaming) runTurn failure still returns HTTP 200 with status: "failed", as before this PR; the HTTP 401 appears from the next request on.

Full suite, rerun sequentially on an otherwise idle machine at 91bf25178, compared with untouched dev (24b2f39b7, run the same way):

• dev: 32,613 pass, 46 skip, 40 fail. These are pre-existing, environment-dependent failures in Claude Desktop, config-PUT, Codex discovery and Kiro tests.
• This branch: 32,650 pass, 46 skip, 26 fail. Of the failures, 4 not in the baseline (cli-connect-readiness, cli-help ×2, cli-export-command), which pass when rerun alone (19/0, 17/0, 26/0). So there are no regressions against dev.

The other CI jobs, run locally with the same commands as ci.yml: typecheck, privacy scan, structure:check, skill:surface:check, release-helper syntax, CLI help smoke, the storage-policy tests and (where docs changed) the docs-site build all pass. The api-usage job's tests/server/api-usage.test.ts fails the same 2 tests (SpendLedgerOwnerError) on untouched dev, locally and in a Linux oven/bun:1.3.14 container, while it passes on GitHub's runner; it is not affected by this PR.

📝 Walkthrough

Walkthrough

Devin OAuth requests now support pre-output 401 recovery through forced credential refresh or eligible account failover. Local CLI key adoption checks the host and account identity. Tests cover recovery, identity checks, concurrent requests, and 429 handling.

Changes

Devin OAuth recovery

Layer / File(s)	Summary
Devin CLI credential refresh src/oauth/devin.ts	refreshDevinToken can reread a local CLI credential and adopt a changed key after host and account identity checks. Probe timeouts and transient probe failures are handled separately from rejected or mismatched identities.
OAuth refresh and terminal failover src/oauth/index.ts, src/oauth/kiro-terminal-failover.ts, src/server/responses/adapter-dispatch.ts, src/server/responses/request-transport.ts	OAuth refresh callbacks receive the stored credential and account ID. Devin is added to forced refresh after a 401. Terminal failover is generalized to configured providers, while the Kiro-specific wrapper remains.
Responses preflight recovery src/server/responses/run-turn-execution.ts	Streaming and buffered preflight share recovery for eligible OAuth 401s and account rotation for 429s. Recovery adopts the selected account and replays the attempt.
Recovery tests and documentation tests/responses/responses-devin-401-replay.test.ts, tests/fixtures/test-layout-expected.json, scripts/test-layout/layout.json, structure/transports/responses-failover.md	Tests cover revoked credentials, alternate accounts, CLI key identity checks, concurrent requests, and 429 handling. The documentation describes the recovery behavior, and the test-layout mappings classify the new test.

Devin 키가 거절당해도 계정이 정상으로 남던 문제를 고치는 PR이에요.

Devin 키에는 만료 시각이 없고, 키를 다시 발급받는 주소도 없어요. 그래서 서버가 401을 줘도 대시보드는 그 계정을 건강한 계정으로 봤어요. 401을 보고 다시 로그인을 요구하는 처리는 HTTP 응답에만 있었는데, Devin은 그 길이 아니라 턴을 직접 실행하는 길이라 그 처리를 타지 못했어요. 죽은 계정이 계속 선택되고, 요청은 매번 401로 실패했어요. 계정이 여러 개여도 죽은 쪽으로 계속 갔어요.

CLI로 가져온 계정도 비슷해요. credentials.toml을 가져올 때 한 번만 복사해서, 나중에 devin auth login으로 키가 바뀌어도 opencodex는 옛 키를 붙들고 있었어요.

이번 변경은 그 두 구멍을 메워요. 턴이 사용자에게 글을 보내기 전에 401이 오면, 그 계정만 한 번 갱신해요. 갱신이 되면 같은 턴을 다시 시도해요. 갱신이 끝까지 실패하면 계정을 needsReauth로 표시하고, 다른 저장 계정이 있으면 그쪽으로 넘겨요. 없으면 ocx login devin을 안내해요. 429나 사용량 거절은 로그인 실패로 보지 않아요.

CLI 계정은 갱신할 때 자격 파일을 다시 읽어요. 파일의 키가 저장된 키와 다르고, 주소가 허용 목록에 있고, 그 키로 사용자 신원을 확인할 수 있고, 그 신원이나 키가 다른 계정 것이 아닐 때만 새 키를 받아요. 시간 초과나 네트워크 오류, 5xx, 429는 계정을 죽이지 않아요. 다음 401에서 다시 시도해요.

Kiro에만 있던 "갱신이 끝난 뒤 다른 계정으로" 기능도 같이 일반화했어요. 방금 needsReauth가 된 계정도 계정 수에 넣어서, 계정이 두 개일 때 하나가 죽자마자 교체가 꺼지지 않아요.

src/oauth/devin.ts:307 - 자격 파일을 읽지 못하면(unreadable, incomplete) 키가 거절된 것과 같은 invalid_grant로 떨어져요. 그 오류는 계정을 needsReauth로 만들고, 그 계정은 이후 갱신을 다시 타지 않아요. 파일이 잠깐 잠겨 있거나 devin auth login이 파일을 쓰는 중이면, 키는 살아 있는데도 계정이 멈춰요. 바로 위 주석은 시간 초과나 네트워크 실패로는 계정을 표시하지 말라고 하는데, 파일 읽기 실패는 그 보호 밖에 있어요.

메인테이너의 판단이 필요한 지점

브라우저로 로그인한 Devin 계정은 업스트림 401이 한 번이면 바로 needsReauth예요. 확인용 호출이 없어요. 서버가 401을 잘못 주면 사용자는 ocx login devin을 다시 해야 해요. 구조 문서에 그렇게 적혀 있으니, 그 선택을 유지할지 정해 주세요.

이 PR은 draft예요. 인증 코드를 건드려서 maintainer-sponsored가 없으면 hygiene가 실패하고, 준비 체크리스트도 비어 있어요.

너의 추천

죽은 키가 건강해 보이던 버그는 이 방향으로 막는 게 맞아요. 다만 307번 줄에서 파일을 못 읽은 경우는 invalid_grant로 보내지 말고, 신원 확인이 잠깐 안 될 때처럼 계정을 표시하지 않는 오류로 올려 주세요. 파일이 없거나, 키가 401/403으로 거절된 경우만 needsReauth로 두면 돼요. 그 다음 메인테이너가 보안 리뷰 라벨을 붙이고 draft를 풀어 주세요.

Thanks for the review.

src/oauth/devin.ts:307: an unreadable or incomplete credential file fell through to invalid_grant. Fixed in aa3e0727c. A credentials.toml that exists but can't be read or parsed (briefly locked, or caught mid-write by devin auth login) now fails the refresh with the same non-terminal error as a transient identity-probe failure. The account isn't flagged, and the next 401 retries. Only a missing file or a key Cognition refuses (401/403, or a token without auth_uid) marks it needsReauth, as you suggested. There's a regression test: a half-written file (key line present, server line not yet) leaves the account unflagged without calling the mint, and once the write completes the next 401 adopts the rotated key. It fails without the fix. The structure doc says the same.

Browser-login accounts flagged on a single 401. I kept this deliberately. Cognition has no refresh endpoint, so there's nothing to confirm with. A GetUserJwt probe with the same key would add a round trip to every 401, and it answers from the same auth backend that just refused the key. The cost of a false flag is one ocx login devin. The alternative, a dead key that looks healthy and fails every turn, is the bug this PR fixes. It's your call to keep or change.

Security review: understood. This touches src/oauth/*, so it needs a maintainer's review and the maintainer-sponsored label. It has had three independent adversarial passes so far (correctness, security, and a re-review of the follow-up), summarized in the description.

[wtfsayo]

@lidge-jun requesting security review and the maintainer-sponsored label. The only failing checks (hygiene and enforce-target) are both unsponsored_surface, because the fix touches src/oauth/devin.ts, src/oauth/index.ts and src/oauth/kiro-terminal-failover.ts.

What the auth surface change does, for the review:

• Credential flow: a Devin runTurn 401 before any output forces one refresh of the account that was actually sent. A terminal failure marks that account needsReauth and fails over within genericFailoverLimit. The replay is gated on the replay list, authMode === "oauth" and a held snapshot; Devin is the only runTurn provider on that list.
• Key adoption: for local-cli accounts, the CLI credentials.toml is re-read only on that forced refresh. The key is adopted only if the host passes validateDevinApiBaseUrl (checked before any request), it mints a user JWT (5 s bound), the minted auth_uid/email do not contradict the slot, and no other account owns the key or that identity.
• Transient failures: only a 401/403 from that mint or a missing file flags the account. A timeout, 5xx, 429, or an unreadable or half-written file does not.
• Not logged: no token, JWT, email or file content goes into any log, error, hop record or management response.
• Shared-code changes: the refresh lock passes the account id to provider refresh functions as an optional argument, and refreshResolvedOAuthSelection now refreshes whenever the current selection is the sent account (the A → B → A case CodeRabbit found). Kiro's terminal failover is generalized with its behaviour preserved.

Review so far: three independent adversarial passes (correctness, security, and a re-review of the follow-up), CodeRabbit (its one finding is fixed and confirmed), and your grok-bot review (its finding is fixed in aa3e0727c). The xAI, Antigravity, Kiro and OAuth 401-replay suites pass one file per process. Suggested area label: account-pool.
