📝 Walkthrough

Walkthrough

The PR adds native auth.json credential refresh, shared refresh locking, credential synchronization with stored accounts, asynchronous authentication materialization, and one-time native-main 401 replay for Responses and compact requests. It also adds focused tests and documents two related engineering lessons.

Changes

Native Codex refresh flow

Layer / File(s) Summary
Refresh transport and lock foundations
src/oauth/chatgpt.ts:5-197, src/codex/auth-collision.ts:14-55, src/codex/account-store.ts:1-522
ChatGPT token parsing now exposes normalized refresh responses. Auth-file parsing preserves refresh_token. Refresh locks use owner records, stale-lock quarantine, reclaim coordination, abort handling, and configurable directories.
Native credential persistence and convergence
src/codex/main-account.ts:1-261, src/codex/account-store.ts:206-717, src/codex/account-usability.ts:3-33, tests/codex-main-account-refresh.test.ts:1-236, tests/codex-account-store.test.ts:235-258, tests/codex-refresh-file-lock.test.ts:1-158
Native credentials refresh with skew-aware usability checks, atomic auth-file persistence, grant reuse, reauthentication updates, and publication to matching stored accounts. Tests cover persistence, concurrency, grant synchronization, and lock cleanup.
Authentication resolution and 401 replay
src/codex/auth-context.ts:6-605, src/server/responses/core.ts:103-4038, src/server/responses/compact.ts:54-724, src/usage/log.ts:27-215, src/routing/analytics.ts:120, tests/responses-native-main-refresh.test.ts:1-65, tests/responses-compact-native-main-refresh.test.ts:1-61
Native authentication refreshes before upstream I/O. Responses and compact handlers map refresh failures to responses and replay one main-pool 401 with refreshed headers. The codex-main-401 recovery kind is recorded and recognized by routing analytics. Integration tests cover pre-request refresh and 401 replay.

Documented lessons

Layer / File(s) Summary
Investigation and postmortem records
LEARNED_LESSONS.md:1-101
The document records the separate __main__ authentication path and the metadata, testing, and review rules from the PR #963 and PR #965 postmortem.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟠 High · up to f46de

This PR changes native credential refresh and account convergence, but the current implementation can still lose refresh-state metadata, attribute requests to the wrong account, hang during authentication, disable valid accounts after timeouts, or leave users blocked behind stale refresh locks. These are high-impact merge-readiness risks, so the changes should not merge until the identified fixes and validation are complete.

only still-valid issues, skip the rest with a brief reason, keep changes
minimal, and validate.

Inline comments:
In `@LEARNED_LESSONS.md`:
- Around line 63-68: Update the issue references in the lesson text beginning
with “#962” and “#963” to use the requested “Issue” and “PR” prefixes with a
separating space, preserving their existing meaning while avoiding Markdown
heading syntax.

In `@src/codex/account-store.ts`:
- Around line 635-636: Remove the unused current assignment in the locked
refresh flow, leaving a single readCodexAccountRecord(id) call assigned to
lockedRecord before the existing run logic.
- Around line 384-402: In src/codex/account-store.ts lines 384-402, update
quarantineStaleRefreshLock so unlinkSync(retiredPath) cleanup failures are
swallowed rather than rethrown, preserving the primary renameSync error. In
src/codex/account-store.ts lines 514-519, wrap the await releaseRefreshLock(...)
cleanup in try/catch that ignores release failures, preserving errors from
args.run() and the existing reauthentication flow.
- Around line 536-567: Update publishFreshCredentialForGrant to preserve each
candidate credential’s existing chatgptAccountId while replacing only its
refreshed token material and related credential fields. Ensure the stored-first
path in main-account refresh remains consistent with this per-record identity
behavior, and update the native-first test expectation to "pool-account" so both
refresh orders are deterministic.
- Around line 206-207: Document the refresh grant identity invariant near
saveCodexAccountCredential and saveCodexAccountCredentialIfGeneration: account
creation and reauthentication must generate a new fingerprint, while
refresh-token rotation must preserve the existing fingerprint. Keep the comment
focused on preventing these distinct behaviors from being unified.
- Around line 404-434: Update acquireRefreshReclaimLock and
tryAcquireRefreshReclaimLock so that after an EEXIST failure they call
refreshLockIsStale(reclaimPath), remove the reclaim file only when the lease and
PID checks identify it as stale, and retry acquisition; preserve fresh reclaim
files and existing timeout/abort behavior.

In `@src/codex/main-account.ts`:
- Around line 77-85: Unify isMainAccountTokenLive and
isMainAccountCredentialUsable around the same auth.json reader and token
normalization path, preserving distinct missing, invalid, and unreadable error
handling instead of collapsing failures to null. Update mainAccessTokenFresh to
accept an explicit skew parameter, then call it with zero skew in
isMainAccountTokenLive and CODEX_REFRESH_SKEW_MS where the freshness margin is
required.
- Around line 213-232: Update the credential rotation flow so
persistMainAuthJson(lockedAuth) completes before publishFreshCredentialForGrant
is called, making auth.json the first store written. Reuse a single computed
account ID for both the credential payload and lockedAuth.tokens.account_id,
preserving the existing fallback order and grant-related arguments.
- Around line 238-249: Preserve the original non-abort, non-lock error in the
catch block around the Codex main-account refresh by extending TokenRefreshError
and passing the error as its cause. Keep tokenRefreshReason and reauthentication
marking behavior unchanged, and ensure any codex-main-401 diagnostic remains
redacted without exposing token material from upstream error messages.
- Around line 224-232: Remove refresh_grant_fingerprint from the
lockedAuth.tokens object persisted by persistMainAuthJson. Store the fingerprint
in OPENCODEX_HOME/codex-accounts.json keyed by MAIN_CODEX_ACCOUNT_ID, and update
the refresh logic around the existing fingerprint hashing and same-grant
matching to read it from that account store so it survives Codex auth.json
rewrites.
- Around line 116-120: Update persistMainAuthJson to import and call
assertNotRealHomeUnderTest immediately after resolveCodexHomeDir(), before the
directory creation or file write, preventing tests from modifying the real home
auth.json when CODEX_HOME is unset.

In `@src/oauth/chatgpt.ts`:
- Around line 5-7: Use the exported CHATGPT_CLIENT_ID and CHATGPT_TOKEN_URL from
chatgpt OAuth constants in account-store and agent-task-recovery production
paths; import the appropriate shared symbols and remove their local
redeclarations, preserving existing refresh and token-validation behavior.

Apply the same fix in `@src/codex/account-store.ts` around lines 694 - 712: The
pool refresh path duplicates transport parsing and validation.
- Around line 189-198: Update refreshChatGPTToken and the OAuth provider
callback in refreshChatGPTTokenRaw’s call path to accept and forward the OAuth
cancellation signal. Add a 30-second timeout combined with the caller’s signal,
ensuring the underlying fetch is always bounded while preserving
caller-triggered cancellation.

Apply the same fix in `@src/codex/auth-context.ts` around lines 467 - 481:
Timeouts currently can disable an otherwise valid account and escape the
resolver's error mapping.

In `@tests/codex-main-account-refresh.test.ts`:
- Around line 169-177: Strengthen the second forceRefreshMainAccountToken
assertion by making its refresh dependency throw if invoked, or by tracking and
asserting zero invocations. Preserve the existing checks that the second call
and pool retain freshAccess, ensuring the test verifies adoption of the
published credential rather than a redundant upstream refresh.
- Around line 136-137: Update the timeout rejection assertion in the refresh
test to verify the error has name "TimeoutError" rather than relying only on
DOMException instance checks, while preserving the expectation that refreshCalls
remains zero.

In `@tests/codex-refresh-file-lock.test.ts`:
- Around line 134-139: Update both long-signal tests, including “quarantines
malformed debris and releases owner-safe locks,” to pass an explicit per-test
timeout as the third argument to test(), using a value longer than their 4,000
ms and 5,000 ms signal budgets so assertions can complete.
- Line 26: Replace the path.split("/").at(-1) basename extraction in the
affected assertions with node:path’s basename function, updating all occurrences
around the lock-file assertions including lines 26, 64, and 86; ensure basename
is imported and used with the existing path values so the checks work across
platforms.
- Around line 8-11: Export the existing codexRefreshLockPath helper from
account-store, import it in the lock-file tests, remove the local lockPath
duplicate, and use codexRefreshLockPath(key, directory) wherever the test
computes the lock-file path.

In `@tests/responses-compact-native-main-refresh.test.ts`:
- Around line 56-57: Add a focused failure-path test alongside the existing
compact response tests, invoking handleResponsesCompact with
NativeMainRefreshDependencies.refreshToken throwing TokenRefreshError. Assert
the exact status returned by nativeMainRefreshFailureResponse and verify the
upstream fetch is never called, preserving the guarantee that failed refreshes
do not forward the admission secret.
- Around line 16-21: Isolate both native refresh test suites from the
developer’s real configuration directory by saving, setting, and restoring
OPENCODE_HOME alongside CODEX_HOME. In
tests/responses-compact-native-main-refresh.test.ts lines 16-21 and
tests/responses-native-main-refresh.test.ts lines 16-21, update the
beforeEach/afterEach hooks while preserving the existing CODEX_HOME setup and
cleanup.

In `@tests/responses-native-main-refresh.test.ts`:
- Around line 37-41: Add a regression test beside the existing native-main 401
test that makes the upstream in its fetch handler always return 401, then assert
the response remains 401 and exactly two upstream requests occur. Extract the
shared config and dependencies setup into a helper so both tests exercise
identical routing while preserving the existing refreshed-bearer assertion.
- Around line 31-32: Rename the jwt(3_600) fixture from stale to a name
indicating it is the initially valid token used before the forced refresh, and
update its references at the request setup and bearer assertion locations.
Preserve its future expiration value so getValidMainAccountToken does not
pre-emptively refresh it and the 401 replay path remains exercised.

Document the refresh grant identity invariant.

saveCodexAccountCredential intentionally starts a new fingerprint for account creation and reauthentication (src/codex/auth-api.ts:508, 1959). saveCodexAccountCredentialIfGeneration preserves the fingerprint for refresh-token rotation. Add a comment at src/codex/account-store.ts:135-137 so these rules are not unified accidentally.

Two finally blocks in the lock machinery can throw, and each throw discards the primary error. In both sites the finally performs best-effort cleanup of a disposable lock artifact. When that cleanup fails, the thrown cleanup error replaces the real failure, so the caller loses the information it needs to react correctly. Biome flags the first site as lint/correctness/noUnsafeFinally.

  • src/codex/account-store.ts#L384-L402: stop rethrowing the unlinkSync(retiredPath) failure in quarantineStaleRefreshLock; swallow it, because the retired file is a leftover and a Windows EBUSY there currently fails an otherwise successful stale-lock reclaim and hides a renameSync error.
  • src/codex/account-store.ts#L514-L519: wrap the await releaseRefreshLock(...) call in try { ... } catch { }, because releaseRefreshLock throws signal.reason on the aborted path and can replace a TokenRefreshError("revoked", ...) from args.run(), which makes src/codex/main-account.ts line 248 skip markAccountNeedsReauth.

Recover stale .reclaim locks

If the process holding ${path}.reclaim exits, the file remains indefinitely. acquireRefreshReclaimLock then polls for 65 seconds and throws CodexCredentialRefreshLockTimeoutError. Add the existing refreshLockIsStale(reclaimPath) lease and PID check after EEXIST. Remove only stale reclaim files and retry acquisition. Apply the same retry logic in tryAcquireRefreshReclaimLock for the aborted cleanup path. Preserve fresh reclaim files.

🗄️ Data Integrity & Integration | 🟠 Major | 🏗️ Heavy lift

publishFreshCredentialForGrant overwrites chatgptAccountId on every same-grant account, so the routed identity depends on which side refreshed first.

Line 557 replaces the candidate's whole credential object with args.credential, including chatgptAccountId. The caller in src/codex/main-account.ts lines 215-220 builds that credential with the main account's identity (token.accountId ?? extractAccountId(...) ?? locked.chatgptAccountId). So a stored pool account keyed under its own chatgptAccountId has that field rewritten to the main account's value.

Your own new tests encode both outcomes for the same grant:

  • tests/codex-main-account-refresh.test.ts line 160, native-first: expect(poolToken.chatgptAccountId).toBe("main-account").
  • tests/codex-main-account-refresh.test.ts line 205, stored-first: expect(refreshed).toEqual({ accessToken: freshAccess, chatgptAccountId: "pool-account" }).

chatgptAccountId becomes the chatgpt-account-id request header (see src/server/responses/compact.ts, where override.chatgptAccountId is set on the outbound headers). So the header sent upstream for a given account now depends on refresh ordering, which is a race, not a configuration choice. If the two identities are genuinely equivalent for a shared grant, the flip is harmless but the tests are asserting an arbitrary winner. If they are not equivalent, requests are attributed to the wrong ChatGPT account.

Preserve each record's own chatgptAccountId and rotate only the token material:

🛡️ Proposed fix
       store[candidateId] = {
         ...candidate,
-        credential: args.credential,
+        credential: {
+          ...args.credential,
+          // The grant is shared; the account identity of each record is not.
+          // Rewriting it makes the outbound chatgpt-account-id header depend
+          // on which side refreshed first.
+          chatgptAccountId: candidate.credential.chatgptAccountId,
+        },
         generation: candidate.generation + 1,

Then update the assertion at tests/codex-main-account-refresh.test.ts line 160 to expect "pool-account", which makes both directions deterministic.

If sharing the identity is intentional, please state that invariant in a comment here and make the stored-first path at src/codex/main-account.ts lines 199-207 agree, because it currently adopts sameGrantFreshCredential.chatgptAccountId into auth.json and produces the opposite result.

Set an explicit per-test timeout for the long-signal tests.

Line 136 waits up to 4000 ms and line 151 waits up to 5000 ms. Bun's default per-test timeout is 5000 ms. If the lock path needs its full wait budget, the runner cancels the test before the assertion runs. The failure then reports a timeout instead of the lock behavior that regressed, which hides the real signal.

Pass an explicit timeout as the third argument to test() for both cases.

Both new responses tests redirect CODEX_HOME but not OPENCODEX_HOME, so the refresh path reads and writes the developer's real config directory. CODEX_HOME isolates only auth.json. The native refresh path resolves three more things from getConfigDir(), which reads OPENCODEX_HOME: the codex-refresh-<digest>.lock file created by withCodexRefreshFileLock (src/codex/account-store.ts lines 488-490, including a hardenConfigDir() chmod), the codex-accounts.json read by findFreshCredentialForGrant, and the codex-accounts.json write by publishFreshCredentialForGrant. The result is machine-dependent test behavior plus side effects on real credential state. tests/codex-main-account-refresh.test.ts lines 51-54 already implement the correct pattern.

Add compact-path coverage for a failed refresh; the changed error mapping is untested.

Lines 56-57 assert the success path: one upstream call carrying the refreshed bearer. The PR objectives also require that /v1/responses/compact maps refresh failures, and src/server/responses/compact.ts implements that mapping:

if (
  err instanceof TokenRefreshError
  || err instanceof CodexCredentialRefreshLockTimeoutError
  || err instanceof CodexCredentialRefreshBusyError
  || err instanceof CodexCredentialRefreshStaleError
) return nativeMainRefreshFailureResponse(err, req.signal);

That branch is new behavior on a changed shared handler and no test in this cohort exercises it through the compact route. tests/codex-main-account-refresh.test.ts covers the failure at the main-account layer, not the HTTP mapping.

NativeMainRefreshDependencies already gives you the injection point, so the test is short.

💚 Proposed additional test
test("maps a failed native refresh to the compact refresh-failure response", async () => {
  writeFileSync(
    join(directory, "auth.json"),
    JSON.stringify({ tokens: { access_token: jwt(-60), refresh_token: "refresh", account_id: "main" } }),

      fetch: async () => { upstreamCalls += 1; return Response.json({}); },
    } },
    codexAccounts: [],
  } as unknown as OcxConfig;
  const dependencies: NativeMainRefreshDependencies = Object.freeze({

  const response = await handleResponsesCompact(new Request("http://localhost/v1/responses/compact", {

  });
  // Assert the mapped status from nativeMainRefreshFailureResponse, and that
  // the admission secret never reached upstream.
  expect(response.status).not.toBe(200);
  expect(upstreamCalls).toBe(0);
});

Import TokenRefreshError from ../src/codex/account-store, and replace not.toBe(200) with the exact status that nativeMainRefreshFailureResponse returns.

The expect(upstreamCalls).toBe(0) assertion is the valuable one: it pins the "fail before any upstream I/O" invariant stated in materializeCodexUpstreamAuthAsync, which exists to stop the admission secret from being forwarded.

That is deliberate and necessary. getValidMainAccountToken (src/codex/main-account.ts line 259) calls mainAccessTokenFresh(token.accessToken), which returns true for this token, so no pre-emptive refresh occurs and the first upstream request carries this exact bearer. The 401 at line 39 is then what triggers forceRefreshMainAccountToken, and line 61 can assert the two distinct bearers.

The name says the opposite of the mechanism. A maintainer reading "stale" will reasonably "correct" line 31 to jwt(-60). The consequence is not a clear failure: the pre-emptive refresh in getValidMainAccountToken would fire first, the first upstream bearer would already be fresh, observedBearers would become ["Bearer <fresh>"] with no 401 at all, and line 61 would fail with a confusing diff. The test would then likely be "fixed" by relaxing the assertion, and the 401 replay path this file exists to cover would no longer be exercised.

♻️ Proposed change
-  const stale = jwt(3_600);
-  const fresh = jwt(7_200);
+  // Deliberately NOT expired: mainAccessTokenFresh() must accept this token so
+  // no pre-emptive refresh runs and the FIRST upstream request carries it.
+  // The upstream 401 below is what must trigger the refresh and the replay.
+  // Changing this to an expired exp moves the test onto the pre-emptive
+  // refresh path and stops covering the 401 replay entirely.
+  const acceptedButRejectedUpstream = jwt(3_600);
+  const refreshed = jwt(7_200);

Update lines 44 and 61 to the new names.

🩺 Stability & Availability | 🔵 Trivial | ⚡ Quick win

Add a case where upstream returns 401 twice, to pin the "one retry" bound.

This server 401s only the first request, so line 61 confirms that a replay happens and that it carries the refreshed bearer. It cannot confirm the upper bound. The PR objective is "retries one native-main 401", and the failure mode of an unbounded replay loop is far worse than a missing replay: each iteration performs a refresh and a full upstream request, so a persistently-401ing upstream would spin.

A second test that always returns 401 makes the bound explicit.

💚 Proposed additional test
test("does not replay a native-main 401 more than once", async () => {
  const first = jwt(3_600);
  const observedBearers: string[] = [];
  const upstream = Bun.serve({
    hostname: "127.0.0.1",
    port: 0,
    fetch(req) {
      observedBearers.push(req.headers.get("authorization") ?? "");
      // Always reject, so an unbounded replay loop would keep appending here.
      return Response.json({ error: { message: "expired" } }, { status: 401 });
    },
  });
  try {
    writeFileSync(
      join(directory, "auth.json"),
      JSON.stringify({ tokens: { access_token: first, refresh_token: "refresh", account_id: "main" } }),
    );
    // ...same config and dependencies as the test above...
    const response = await handleResponses(/* ...same request... */);
    expect(response.status).toBe(401);
    // Exactly one replay: the original attempt plus one refreshed retry.
    expect(observedBearers).toHaveLength(2);
  } finally {
    upstream.stop(true);
  }
});

Extract the shared config and dependencies construction into a helper so both tests use identical routing, which also keeps the two tests from drifting.

As per path instructions: "A behavior change in src/ should come with a focused regression test near the existing tests for that subsystem."

구멍은 맞음. 지금 dev__main__src/codex/main-account.ts getMainAccountToken() / isMainAccountTokenLive()로만 봄. JWT exp 지나면 사용 불가고, 살아 있어도 src/codex/auth-context.tsauth.json 액세스 토큰을 그대로 주입함. 풀 계정은 getValidCodexToken()이 리프레시하는데 메인만 빼먹음. ~/.codex/auth.jsonrefresh_token이 있어도 만료 베어러가 /v1/responses로 가서 401 남. Option A 주석이 read-only라서 리프레시를 안 한 거임.

이 PR은 isMainAccountCredentialUsable로 리프레시 토큰만 있어도 라우팅 후보로 넣고, getValidMainAccountToken / forceRefreshMainAccountTokenauth.json을 원자 기록함. 같은 grant 핑거프린트로 풀 계정과 수렴. 401은 Responses랑 compact에서 한 번만 리플레이. codex-main-401 로그는 레드액션 유지. 락은 owner/pid/quarantine으로 키움. 방향은 맞음.

범위가 큼. +1487줄. 락 재작성 + oauth 파서 + compact/core 리플레이를 한 방에 넣음. 루트 LEARNED_LESSONS.md는 지금 dev에 없는 새 파일임. 세션 경로랑 #963/#965 이야기까지 들어 있음. 이 핫픽스랑 무관함. 넣지 말 것. #2221은 재현 스텝 없어서 봇이 닫음. 그 이슈를 다시 열어 맞추지 말고 이 PR 본문이 스펙임.

draft고 intake: hygiene-blocked. unsponsored_surfaceauth-collision.ts / auth-context.ts / oauth/chatgpt.ts. 메인터가 maintainer-sponsored 달기 전엔 머지 금지. auth.json을 쓰기 시작하니 Codex CLI랑 파일 레이스가 생김. 락이 그거 막는지 보안 리뷰에서 확인해야 함. isMainAccountCredentialUsable은 액세스 토큰이 있어야 파싱함. 리프레시만 있고 액세스가 빈 파일은 여전히 탈락임. 그 엣지 테스트가 필요함.

types.ts 스플릿은 안 씹힘. config.ts atomicWriteFile만 씀. 스플릿이 그 헬퍼를 옮기면 리베이스하지 말고 닫고 다시 짜라. 지금은 그 정도 아님. #2188 사이드카, #2190 x_search랑 섞지 말 것. 2.28 블로커도 아님. 네이티브 메인 401은 체감이 커서 점수는 높음. 프로세스 게이트가 안 열렸을 뿐임.

해결방안: LEARNED_LESSONS.md 빼고, hygiene 통과 + maintainer-sponsored 받은 뒤에 draft 해제. 401 리플레이는 한 번만. 이미 본문이 나온 뒤에 리플레이하면 안 됨. auth.json 쓰기 실패는 fail-closed 유지.

Triage disposition from the current bug-backlog train: the gap is real and confirmed — pool accounts refresh through getValidCodexToken() but the native main path never refreshes, so an expired auth.json bearer 401s /v1/responses even when a refresh_token is present. Reproduction reasoning matches src/codex/main-account.ts (getMainAccountToken/isMainAccountTokenLive) and src/codex/auth-context.ts injecting the stored access token as-is. HOWEVER this PR modifies credential/token handling (auth.json writes, refresh locking, 401 replay with a fresh bearer), which MAINTAINERS.md reserves for explicit human security review — so it is deliberately NOT being admin-merged in this train despite the pre-approval covering ordinary fixes. Requesting maintainer security review; also note the intake hygiene block still stands. Once reviewed, the rebase itself should be mechanical (current dev has no conflicting changes in the touched files as of head 08cc2ac).

The underlying bug is real, and the direction is useful, but this exact head is not safe to sponsor or merge yet. I independently reviewed f46deab84ba177a0a32354502f486192545fac64, including the credential stores, lock lifecycle, Responses/compact paths, changed tests, typecheck, and privacy scan.

Blocking items:

  1. The PR claims one native-main 401 replay for compact, but handleResponsesCompact only refreshes before the first send. A locally fresh JWT that is rejected by upstream is returned as 401 without calling forceRefreshMainAccountToken. I reproduced this with a focused probe: one compact upstream request, zero refresh calls, final 401. Add the same bounded one-replay contract to compact and a regression where the first compact request 401s and the refreshed replay succeeds; also pin the always-401 upper bound.

  2. The new file lock does not coordinate the writer it is intended to protect against. withCodexRefreshFileLock creates an OCX lock under OPENCODEX_HOME, while persistMainAuthJson replaces CODEX_HOME/auth.json. Native Codex does not participate in that OCX lock, so a concurrent native CLI refresh can still race this writer. Use a native-compatible coordination/CAS contract, or re-read and reject a changed auth generation immediately before replacement, and add a concurrent external-writer regression.

  3. The refresh commits the matching pool store first and auth.json second. If persistMainAuthJson fails, rotated grant state has already been published to pool records while the native file remains stale. Persist the authoritative native file first, then converge pool records only after that succeeds. Add a failure-injection test proving no pool mutation occurs when the native write fails.

  4. Existing .reclaim debris is never checked for staleness after EEXIST. The async path polls until timeout and the sync path returns null, even for a dead owner or malformed record. Reclaim only after the same lease/PID stale checks used for the primary lock, and ensure cleanup failures do not replace the original refresh error.

  5. Both new response test files isolate CODEX_HOME but not OPENCODEX_HOME. The exercised path also creates the refresh lock and reads/writes codex-accounts.json, so the tests can touch the developer's real OCX credential store. Isolate and restore both homes, add the real-home test guard before native writes, and keep the tests safe when the full suite runs together.

  6. Remove the unrelated root LEARNED_LESSONS.md. This hotfix should stay scoped to the refresh contract.

Repository gates also still block this head: it is Draft, hygiene is failing, maintainer-sponsored is intentionally absent, unresolved review threads remain, and it is now 206 commits behind current dev. Rebase only after the fixes above, then rerun the exact-head focused suites, typecheck, privacy scan, and maintainer security review. I will not apply sponsorship until that corrected head is reviewed.

Security disposition: no reportable remote vulnerability survived review, but the credential-boundary correctness and durability blockers above are sufficient to prevent merge.
