📝 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.

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.

Reviewed exact head d54acacd79368ea388a22e72cd425bdfd8f84d9b. The underlying native-main refresh gap is real, and removing the unrelated LEARNED_LESSONS.md resolved one prior scope blocker, but this head is still not safe to sponsor or merge.

The current blockers are concrete:

  1. handleResponsesCompact still has no bounded native-main 401 refresh/replay. It refreshes an already-expired JWT before the first send, but a locally fresh bearer rejected by upstream is returned directly. The only compact regression still covers pre-send expiry; add first-401-then-success and always-401 upper-bound tests.

  2. withCodexRefreshFileLock still locks under the OpenCodex config directory, while the protected file is native CODEX_HOME/auth.json. Native Codex does not participate in this lock. forceRefreshMainAccountToken reads auth.json, awaits the network refresh, and later replaces the file without re-reading or comparing the native generation. A concurrent Codex refresh/login can therefore be overwritten. Add a native-compatible coordination or compare-and-swap contract immediately before replacement, with an external-writer regression.

  3. The fresh credential is still published to matching pool records before persistMainAuthJson. If the native atomic write fails, pool state has already advanced while authoritative auth.json remains stale. Persist native state first, then converge pool records; add failure injection proving the pool is unchanged on native-write failure.

  4. Stale .reclaim debris is still not reclaimed. acquireRefreshReclaimLock handles EEXIST only by polling until timeout; it never applies the owner/PID/lease stale checks used for the primary lock. Add stale and malformed reclaim recovery tests while preserving fresh-owner safety.

  5. The two response regressions still isolate only CODEX_HOME, not OPENCODEX_HOME. On this exact head, the five focused suites produced 41 passes and 2 failures because those tests consumed the caller's real OCX state and returned 503. Running only those two tests with a fresh OPENCODEX_HOME produced 2/2 passes. Isolate and restore both homes and add the real-home write guard.

  6. The owner Grok review's refresh-only edge remains: mainTokenFromAuth returns null unless access_token is present, so isMainAccountCredentialUsable cannot admit an otherwise recoverable auth file containing a valid refresh_token but an empty/missing access token. Add the edge regression and construct refreshability independently of access-token parsing.

Typecheck and privacy scan pass, but focused exact-head testing is not hermetic and repository gates remain red (hygiene, enforce-target); the PR is also still Draft. Please keep it open, fix the six boundaries above, rebase onto current dev, and rerun exact-head focused/full CI plus human security review. I am not applying maintainer-sponsored on this head.

Security disposition: I did not confirm a new remotely exploitable vulnerability in this diff. These are credential-integrity, concurrency, and test-safety blockers at a security boundary and are sufficient to prevent merge.

Closing as superseded in planning rather than in code, and I want to be straight about the state: #2221 is not fixed, and your approach is largely right.

A security audit of the replacement plan (recorded in devlog/_plan/260822_backlog_disposition_program/050_*) reached the same architecture you did — pre-request refresh for the native __main__ account, sharing the pool's existing grant file-lock, exactly one 401 replay, and cross-domain publication between auth.json and the pool rows. That part of your work stands.

Three reasons this branch is not the vehicle:

1. It is stale in a way that matters. Its account-store.ts hunks re-add the expiry finite/negative guards that are already on dev, and the branch is CONFLICTING. Large parts no longer apply.

2. It smuggles a pool-wide invariant change into a bugfix. saveCodexAccountCredentialIfGeneration is rewritten so refreshGrantFingerprint stops rotating when the refresh token rotates. That contradicts a currently-passing assertion at tests/codex-account-store.test.ts:257, and it changes behavior for every pooled account — not just the native one.

To be fair to you: the audit concluded you were right that this is needed. Without the freeze, pool-first adoption genuinely breaks — the pool row becomes hash(RT2) while auth.json still holds RT1, so the native lookup misses and then posts a possibly-invalidated grant. Your fix was correct; the problem is that it deserves its own reviewed PR rather than riding along, because it is exactly the kind of change that is invisible in a 2k-line diff.

3. The ~200-line lock rewrite (reclaim lock, PID liveness, abandon set, quarantine) is separable, and the reviewer had already flagged stale reclaim handling. The current lock is adequate for this fix.

Two smaller things worth carrying forward into whatever lands:

  • persistMainAuthJson is a blind atomicWriteFile, and it publishes to the pool before writing the native file. The Codex CLI is a different process that does not honor our lock, so a token it writes during the IdP round trip gets clobbered. The replacement plan now requires capturing file identity plus a content hash at read, re-checking immediately before the rename, and discarding the fetched grant on a mismatch.
  • Writing refresh_grant_fingerprint into auth.json puts an ocx-private field into a file the CLI owns. Preserve unknown fields; don't add ours.

Also flagged for the replacement: your tests mutate CODEX_HOME directly. That is actually the repo's seam — via tests/helpers/isolated-codex-home.ts — but note test-home-guard protects only ~/.opencodex, so ~/.codex is unguarded and an unisolated persist test overwrites real developer credentials.

If you want to take the fingerprint-freeze piece as a standalone PR against dev, that would genuinely unblock this — it is the one decision the replacement is currently waiting on.

…ore code

An independent security audit of the lidge-jun#2221 plan returned four High blockers,
each re-verified against dev. Amendment 2 records them and is authoritative
over both the body and the first amendment.

Two are corrections an implementer can execute: the body's code sample still
blind-writes auth.json even though the first amendment promoted external-writer
CAS into acceptance criteria, and compact has no 401 replay so a grant rotated
by the Codex CLI fails compact while Responses recovers. A third is a missed
case: a file holding a valid refresh_token with an absent access_token is
exactly the state this feature should recover from, and today it reads as
invalid.

The fourth is a fork rather than a fix. account-store.ts:206 recomputes the
refresh-grant fingerprint when the token rotates, pinned by a passing test, so
dropping PR lidge-jun#2222's fingerprint freeze breaks pool-first adoption: the pool row
becomes hash(RT2) while auth.json still holds RT1, and native lookup then posts
a possibly-invalidated grant. Freezing the fingerprint, replacing the same-grant
lookup, or narrowing this phase to native-first each change the shape of the
diff, so the decision belongs to a maintainer and not to a mid-build guess.

This phase therefore stops at the audit. Nothing in src/ changes.

Also corrected here: the first amendment banned CODEX_HOME mutation in tests,
which over-corrected. The repo's seam genuinely is that mutation, through
tests/helpers/isolated-codex-home.ts; lidge-jun#2222's defect was mutating it without
isolation. That distinction matters because test-home-guard protects only
~/.opencodex, so ~/.codex is unguarded and an unisolated persist test would
overwrite a developer's real Codex credentials — and WP5 would be the first
code in this repository to write that file at all.

* release: v2.17.1-preview.20260814

preview now carries the same tree as main and dev (36aed0bf0). The version
string is the only difference, which is what the release workflow requires:
preview publishes prerelease versions under the 'preview' dist-tag.

Before this, the preview channel was 12,065 lines behind dev and still shipped
the Compatibility Lab on every install's request path.

* devlog: bun 1.4 follow-up memory roadmap (000-040) — research ledger, diagnostics/GC-relief/smol-worker plans, macmini measurement protocol

* fix(kiro): accept permissive parallel tool hints

* fix(responses): scope reasoning replay by conversation, not just parent thread

The serving-identity record was keyed only on `x-codex-parent-thread-id`.
Without that header there was no scope at all, so the record could never be
written or compared: every turn stayed permanently cold, the deterministic
pre-flight never fired, and each turn fell through to the opaque-blob
recovery — one extra full upload of the transcript, every turn.

Measured on live traffic. Across 95 xAI conversations, 70 recoveries occurred
and 67 of them were in two conversations:

  f4be51de   86 requests  55 recoveries
  c14e85a7   66 requests  12 recoveries
  e925d065  165 requests   1 recovery     <- healthy: one cold first turn

Both outliers are conversations where the backend was switched mid-session, so
their transcripts permanently carry foreign-minted reasoning blobs replayed on
every later turn. An instrumented build showed those requests carrying no
client thread id, which is why the record never warmed up. Those turns were
~150k input tokens each, sent twice.

The recovery was working as designed — without it the turns would fail
outright. The defect is that the deterministic path was structurally
unavailable to them, so the recovery paid full price every turn instead of
once.

`conversationIdFromResponsesRequest` already resolves a conversation identity
for the request log through a four-level fallback, so reuse it as the replay
scope key when the header is absent. `_clientThreadId` is untouched: it
remains the routing and continuation identity, and the header path is
byte-for-byte unchanged.

The scope is shared with the process-local raw-reasoning replay and the
durable thought-signature replay. Widening is safe for both because they key
additionally by provider, destination, adapter, model and credential, so a
conversation namespace only narrows what they already isolate — and a fallback
that yields no identity still produces no scope, preserving today's keep-the-
blobs behaviour.

Pinned by a three-turn headerless regression asserting sendCount [2, 1, 1]:
recover once, then strip pre-flight. That sequence is the entire point.

(cherry picked from commit 22375cf980ee7990f36f6d6c9d231966ff84102a)

* fix(responses): remember a proven opaque-blob rejection per destination

The serving-identity record tracks which destination served the previous turn.
That is the right signal for detecting a switch and the wrong one for what
actually costs money, because foreign blobs stay in the client transcript
forever while the switch happens only once.

Measured on the deployed build — three consecutive headerless turns replaying
a grok-minted blob to gpt-5.6-sol:

  turn 1  sends=1  recovery=[]                       pre-flight strips, one send
  turn 2  sends=2  recovery=[opaque-blob-rejection]   record now says sol == sol,
  turn 3  sends=2  recovery=[opaque-blob-rejection]   no strip, upstream rejects

After the first turn commits the new destination every later comparison
returns "same identity", so the pre-flight stops stripping while the
grok-minted blob is still in the replayed history. Each of those turns paid a
full extra upload. This is the production pathology: 86 requests / 55
recoveries and 66 / 12 in the two conversations where the backend was switched
mid-session, against 165 / 1 for a healthy one, at ~150k input tokens a send.

When a recovery succeeds the upstream has just proven this conversation's
replayed opaque state is unusable for that destination. Remember it and
pre-strip instead of rediscovering it once per turn.

The memo is keyed by conversation **and** durable serving identity. Keyed by
conversation alone it would strip the original destination's own valid blobs
the moment the user switched back — a silent, permanent quality regression with
no error to notice. It is recorded only when the blobless resend actually
succeeded, so a resend that also failed teaches nothing.

TTL is five minutes against the serving record's hour, and the asymmetry is
deliberate: a stale memo silently degrades reasoning, while an expired one
costs a single visible recovery round trip that re-establishes it.

An earlier attempt at this test alternated destinations between turns, which
passes for the wrong reason — the identity changes every turn, so the ordinary
switch detection fires and the memo is never exercised. The regression now
holds the destination constant and asserts sendCount [2, 1, 1], plus the
switch-back case, a failed resend recording nothing, and expiry rechecking
once before settling.

* fix(tools): repair integral floats in native u64 tool fields

Codex advertises multi_agent_v1__wait_agent's timeout_ms as a JSON Schema
number, but its Rust runtime deserializes the field as u64. Grok serializes
the integer through a float, so a wait of 120000 arrives as 120000.0 and
Codex rejects the call before the tool runs, with an invalid-type error
naming a floating point value where u64 was expected.

The #1611 repair already existed but declined here, because it only fires on
a declared integer. The schema lookup was never the problem: the error text
comes from Codex's own deserializer, which only sees the call after the
bridge emitted it.

Treat a known native u64 field as integer-declared when the schema declares a
numeric type, so the existing re-stringify path emits 120000. A fractional
value is a real disagreement and still fails upstream.

The allowlist is one field wide on purpose. It names only what has a captured
u64 rejection, because the repair is unambiguous only for a field that cannot
hold a fraction; a generic name like start, priority, or port would silently
rewrite a third-party tool's legitimate fractional value. Cursor's sibling
yield_time_ms is also declared number and is deliberately not included: it
gets its own change when it gets its own reproduction.

Array items are judged by their own schema rather than inheriting the key, so
an array named like the allowlist is not rewritten.

Closes #2316

* fix(catalog): keep opencode-free/deepseek-v4-flash-free exposed and prune stale thinking toggle models (#2330)

* devlog: work-phase records for the backlog disposition program

011 records work-phase 1: four green PRs merged (#2309, #2339, #2335, #2313),
#2359 held on a reproduced test failure, a correction to 001 (dev IS protected,
by rulesets rather than classic branch protection), and an honest incident
record of a hard reset that dropped an unpushed commit and how it was recovered.

090 records work-phase 9, the four PRs that arrived mid-loop. #2361 merged;
#2362, #2363 and #2364 left open with their blockers restated. Two of those
verdicts rest on falsification rather than diff reading: #2363's tests still
pass with its real call site deleted, and #2364's second commit deleted the
management validation its first commit added. It also records a CodeRabbit
finding that was dismissed as wrong on the evidence.

* devlog: record the late #2362 review and what retirement cost

The review lane for #2362 was retired under DISPATCH-RETIRE-01 after three
silent wait cycles, and the PR was reviewed directly instead. The lane then
returned with three resolver defects the direct review had missed, each since
reproduced at the PR head: the canonical ChatGPT forward provider can opt into
terminal repair, an invalid per-model grace falls through to the provider
default instead of failing closed, and duplicate case-folded keys resolve by
request casing.

Retiring the lane was right; treating retirement as a verdict would not have
been. Records the rule to re-read a late result against what was already
concluded.

* test(scripts): land the Bun 1.4 memory harnesses with their review blockers closed

Rebuilds the harness halves of #2303 and #2304 directly on dev, without the
#2302 runtime commit those PRs were stacked on. Merging them as stacked would
have dragged in the extraMemorySize: 0 fabrication that #2302 still carries,
and would also have reverted unrelated coordinator work that landed on
src/cli/doctor.ts after the stack was cut.

scripts/bun-gc-relief-eval.ts

  Records rssBeforeLoad and derives postLoadGrowth and recoveryFraction. The
  controlling 260731 gate is "at least 50% of post-load RSS GROWTH is gone",
  and the previous shape could not express that: rssAfterLoad - rssPlus60s
  cannot separate recovery from ordinary drift, and the recorded verdict
  divided recovered bytes by total post-load RSS, which answers a different
  question than the gate asks. recoveryFraction is null when growth was not
  measurable, so a cell that proves nothing does not read as 0% recovery.

  A child-side gc-error now rejects the waiting cell instead of expiring into
  a ten-second "gc receipt timeout" that hides the real cause.

scripts/macos-rss-retention-harness-child.ts

  The SIGUSR2 collector is installed only under OCX_GC_EVAL=1. It was gated by
  a comment saying the 7h retention protocol never sends that signal, which is
  a claim about one sender rather than a property of the process; a stray
  signal would have collected inside the measurement that protocol exists to
  take.

scripts/smol-worker-ab.ts

  payloadMb and runs are validated as bounded integers. Previously runs=0
  produced a report claiming completionSuccess over an empty result set with
  the median fields silently absent, and a negative payload ran a meaningless
  workload instead of refusing. Medians are computed only once both arms are
  complete, so a verdict can never be derived from a partial set.

  The header claimed to measure the audited shapes of history, restore and
  policy workers; it imports none of them. It now says what it is: a synthetic
  screening of the array-plus-JSON burst shape those workers share.

The FAIL verdicts both harnesses recorded stand. No production Bun.gc(true)
call and no smol: true flag is landed here.

The GC harness needs a live upstream fixture to produce new numbers, so the
recorded RSS cells are NOT regenerated by this commit and the 020 table still
carries the old denominator. Re-running the cells and rewriting that table
around recoveryFraction is deliberately left as the next measurement pass
rather than claimed here.

* devlog: work-phase 7 record — Bun 1.4 stack retargeted, not abandoned

Records why the four-PR stack was rebuilt on dev rather than merged: only
#2301 targeted dev, so dev CI never ran on the runtime diff, and a stacked
merge would have reverted coordinator work that landed on src/cli/doctor.ts
after the stack was cut (-94/+6 against current dev).

#2302 was closed rather than landed. It coerces a missing or non-numeric
extraMemorySize into 0 while the watchdog and doctor both type the field
optional, so a counter that was never read would surface as jscExtra=0MB
inside a series whose only purpose is showing whether native memory grows.

Also records the wp1 holdout #2359 landing after the author fixed the
exclusion that broke provider-live-models.test.ts:163, and the close of
issue #2330 with the reasoning for the two slugs deliberately left exposed.

* devlog: work-phase 2 record — one merged, three held on reproduced defects

#2310 merged after every recorded blocker was confirmed closed at its current
head; the earlier objections were against a different implementation.

The three holds share a pattern worth recording: each PR does something its
own description denies, and each one's tests pass either way.

  #2350 says it annotates empty tool outputs. Its Responses emptiness check
  classifies any non-text part as empty, so a real input_image or
  encrypted_content payload is replaced with the annotation. The Chat half of
  the same PR guards correctly.

  #2351 says it never records a secret. Redaction keys off the last path
  segment and the sensitive-key pattern is anchored, so api_key matches but
  bare key does not - and apiKeys[].key is the data-plane admission secret.
  It lands verbatim in config-mutation.sqlite.

  #2355 says it warns while the proxy serves stale config. residentConfigSha256
  is a module global reassigned on every loadConfig(), so an incidental reload
  from catalog sync or a token refresh clears the warning while the old
  snapshot is still being served.

All three were reproduced before being posted. That is the argument for
reverting a hunk and re-running rather than trusting a green check.

* feat(cli): add an opt-in Windows desktop-app restart for a stale model picker

ocx sync --restart-codex deliberately signals only codex app-server and
code-mode-host processes: isCodexAppServerCommandLine requires a codex
executable token, so the Electron shell that owns the model picker is never a
match. On macOS that suffices, because the respawned app-server re-emits
codex-app-server-initialized and the renderer drops its cached model list. On
Windows MSIX it does not, so the picker keeps showing the old catalog until the
app itself restarts.

--restart-desktop-app is therefore a separate flag rather than a widening of
--restart-codex. Quitting the desktop app ends live conversations, which is a
different consent from restarting a background helper, and the documented
contract for --restart-codex promises the narrow behavior. Nothing changes for
macOS or Linux, and passing the flag there prints a no-op rather than acting.

This is the one CLI path that terminates a user's application, so kill
authority is bounded on four axes:

- Package identity is discovered at runtime through Get-AppxPackage. The beta
  MSIX family changes between builds, so a hardcoded AUMID would eventually
  match nothing, or match something we did not mean.
- Targets must be ChatGPT.exe under the discovered InstallLocation AND owned by
  the current user. Path scoping alone is not enough: a WindowsApps package
  directory is shared, so another account's desktop app matches the same path.
  The app-server collector already pays for GetOwner for this reason.
- A PID is re-verified against its CreationDate immediately before the graceful
  close and again before taskkill. The graceful window is long enough for
  Windows to recycle a PID, and the forced pass uses /T /F against a whole tree.
- Ancestry comes from a bounded CIM walk, not process.ppid. A terminal hosted
  inside the desktop app sits several hops below ChatGPT.exe, so a one-level
  check would miss the exact case the guard exists for. An unreadable chain
  fails closed.

Discovery failure, self-ancestry, and any surviving target all skip the
relaunch and tell the user to restart manually. A stale picker is a much
smaller problem than a wrongly terminated process.

The stale-app-server warning, the doctor action line, and the CLI help now
mention the Windows flag, so a Windows user is no longer pointed only at the
flag that cannot refresh their picker.

Refs #2292

* devlog: work-phase 4 record — #2292, and the audit that arrived after retirement

The plan auditor produced nothing across four wait cycles and was retired
under DISPATCH-RETIRE-01, so the main agent audited directly and found zero
blockers. The lane then returned with FAIL and five High blockers, two of
which were real ways to kill the wrong process:

  An MSIX InstallLocation under WindowsApps is shared between accounts, so
  matching ChatGPT.exe by package path alone would have closed another user's
  desktop app. Now requires current-user GetOwner, the same bar the app-server
  collector already pays for.

  A PID can be recycled inside the 15-second graceful window, and the forced
  pass is taskkill /T /F against a whole tree. Now re-verifies CreationDate
  before the graceful close and again before the kill.

Records why the direct audit missed them: it verified everything the plan
said and confirmed every pointer, but did not ask what the plan had left out
relative to the established collector. Both audits were honest; only one was
adversarial.

* devlog: WP5 security audit — native main refresh needs a decision before code

An independent security audit of the #2221 plan returned four High blockers,
each re-verified against dev. Amendment 2 records them and is authoritative
over both the body and the first amendment.

Two are corrections an implementer can execute: the body's code sample still
blind-writes auth.json even though the first amendment promoted external-writer
CAS into acceptance criteria, and compact has no 401 replay so a grant rotated
by the Codex CLI fails compact while Responses recovers. A third is a missed
case: a file holding a valid refresh_token with an absent access_token is
exactly the state this feature should recover from, and today it reads as
invalid.

The fourth is a fork rather than a fix. account-store.ts:206 recomputes the
refresh-grant fingerprint when the token rotates, pinned by a passing test, so
dropping PR #2222's fingerprint freeze breaks pool-first adoption: the pool row
becomes hash(RT2) while auth.json still holds RT1, and native lookup then posts
a possibly-invalidated grant. Freezing the fingerprint, replacing the same-grant
lookup, or narrowing this phase to native-first each change the shape of the
diff, so the decision belongs to a maintainer and not to a mid-build guess.

This phase therefore stops at the audit. Nothing in src/ changes.

Also corrected here: the first amendment banned CODEX_HOME mutation in tests,
which over-corrected. The repo's seam genuinely is that mutation, through
tests/helpers/isolated-codex-home.ts; #2222's defect was mutating it without
isolation. That distinction matters because test-home-guard protects only
~/.opencodex, so ~/.codex is unguarded and an unisolated persist test would
overwrite a developer's real Codex credentials — and WP5 would be the first
code in this repository to write that file at all.

* devlog: WP6 — verify and record the #1049 deferral

Re-checked the deferral against dev rather than inheriting it from the roadmap.
All three conditions still hold: rg -c 'adoption-pending' src/ returns 0, the
eligibility gate still returns legacy-uncoordinated, and the create path still
opens the final database with create:true, which the substrate contract forbids
for adoption-grade publication.

The obvious shortcut is disproven by the code. assertInitialStateCanBeCreated
refuses to initialise a coordinator row while native routing residue exists,
because writing an empty row over routed bytes erases the evidence of an
interrupted transition. That refusal is correct; what is missing is a different
row identity, not a weaker gate.

The prerequisite is larger than the feature: replacing create:true rewrites the
path used by every clean install, and publication is the crash boundary. #1049
stays open with this record linked, rather than a plausible-looking diff being
attached to a crash-safety surface.

* fix(codex): avoid TOML marker regex backtracking

* devlog: WP8 execution and the program's closing reconciliation

Four candidates reviewed at their current heads, all four held back, and a
final count that is honest about a backlog which never stopped moving.

#2083 was the strongest remaining candidate - approved, mergeable, and with
security work that revert-testing confirmed is load-bearing. Its own test file
cannot parse: the mock exports only callXaiImages while fulfill.ts now also
imports resolveXaiAspectRatioLiteral, so the runner dies before any assertion
and the new aspect_ratio regression never executes.

#2366 persists nothing. addRequestLog wrote all five new fields as null and the
function request-history projects through returned them null, while the first
commit says closes #1217.

#2368 is confirmed complementary to the merged #2310 rather than redundant, but
sits 35 commits behind with an unrelated pacing test still bundled. #2033 is 615
behind with its file changed underneath it.

The open count went 45 to 45. That is the useful number: ten PRs merged and
eight closed while roughly as many arrived, three of them after this phase's own
inventory was taken. A backlog with active contributors is a flow, not a queue
that drains, so the measure is whether each item carries a recorded disposition
rather than whether the count fell.

Records the recurring defect class across six held PRs: the code does something
the description denies, and the tests pass either way. None was visible from the
diff; each needed the same move, which is to revert the hunk and watch what does
not go red.

* fix(gui): stop the sidecar copy collapse and align both cards on one control line (#2397)

* devlog: sidecar layout dvh roadmap (docs-only cycle)

* fix(gui): stop the sidecar copy collapse and align both cards on one control line

The dashboard's web-search sidecar card rendered its Korean title as a one-glyph-wide
vertical stripe and grew from 157px to 618px tall, and the two sidecar cards' Select
triggers never shared a baseline.

Copy was `flex: 1 1 0` with a zero floor while the controls were `flex: 0 0 auto` and
nowrap, so copy was the only item that could yield. Once the Korean control row (326px)
outgrew the track its used width reached 0 and `overflow-wrap: anywhere` broke after every
glyph. A 14rem floor makes that unreachable.

The baseline drift was placement, not size: only the vision card wrapped and only it
overrode the shared centre alignment, and the two control groups are different heights. Both
cards now wrap, both reserve the same copy and control bands, and both pack from the top.

Measured across ko/fr/ru/ja/en at 1093-2500px: title 21px, delta selTop 0.0px.

* chore: PR evidence (before)

* chore: PR evidence (after)

* devlog: keep the sidecar before/after evidence with its plan unit

The screenshots were pushed to a scratch .tmp-pr-assets/ path so the PR body could
reference them. They belong with the unit that explains them, not at the repo root.

* fix(gui): move the sidecar cards' responsive axis from the viewport to the card

.dash-sidecar-grid is repeat(auto-fit, ...), so card width is decoupled from viewport
width: a 336px card exists inside a 992px window. The three @media rules that stacked
these cards were measuring the wrong box, firing at widths where the card was comfortable
and staying silent where it was cramped.

The container goes on the card. This could not ship with the layout fix because
container-type: inline-size implies layout containment, which silently disabled the
subgrid that fix briefly used; the shipped layout is flex, so nothing reads a parent row
line any more. Both in-card overlays portal to document.body and the sticky thead is
outside the card, so containment traps nothing.

The 30rem rule was dead code, not a rule to convert: .dash-vision-number renders only
inside the portaled popover, which already sets width: 100%.

Verified by the case a media query cannot express: at a fixed 2000px viewport the rules
turn on and off with the card width alone.

* fix(gui): cap every sidecar control floor at the card width

The container queries reach card widths the old viewport queries never did. A hard
10.5rem/6.5rem select floor is wider than the card down there, so the controls pushed past
the panel edge. min() keeps a floor from exceeding the box it is a floor for. Verified: no
element overflows its card down to a 200px forced card width.

* test(codex): follow #2398 on the oversized pool-retry 400 body (#2404)

#2398 stopped relaying attacker-controlled error prefixes: an oversized upstream body now
becomes #452's bounded status-only JSON instead of being passed through. It added
"oversized passthrough errors become bounded status-only JSON" to assert exactly that,
but left this test asserting the opposite -- that the original 65 KiB body comes back
verbatim. Both were green on their own branches and only collide on dev, because CI tests
the PR head rather than the merge result.

The invariant this test exists for is unchanged and still asserted: an oversized 400 does
not authorize a pool retry, so exactly one account is dispatched and neither is marked
unhealthy. Only the body expectation moves, and it now also asserts the hostile suffix
does not reach the client.

* feat(usage): answer today's cost from the CLI in one command (#2396)

* devlog: plan CLI usage cost query

A user asking "how much did Grok cost me today?" could not answer it with
ocx usage. The proxy prices every request at read time, then the CLI discards
the breakdown before printing: summaryLines() stops at depth 1 and renders
models/providers/accounts as "N item(s)". There is also no today window, day
rows carry no cost field at all, and --surface selects the client rather than
the upstream provider, so --surface grok answers a different question than the
one being asked.

Roadmap unit with diff-level decade docs (data -> api -> cli -> verify) plus
the A-phase audit fold-back. Two independent reviews found seven blockers,
including one that would have poisoned the shared usage cache: the cache key
is range:surface, so a filtered summary written under it would serve filtered
totals to the next unfiltered caller, GUI included.

* feat(usage): add a today window and day-level cost attribution

The proxy prices every request as it reads the log, but day rows carried only
requests and tokens, so per-day cost did not exist anywhere - not even in
--json. Anyone asking what today cost had to re-derive prices the proxy had
already computed.

buildDayGrid now prices through the same seam buildModels uses: combo requests
are priced per attempt and each attempt's cost is attributed to its own model,
everything else to the entry's model. Pricing it a second way would have made
days[] disagree with models[] for exactly the combo traffic where the
disagreement is hardest to spot.

Three details worth naming:

- rangeWindow has no exhaustive switch; its final return is the "all" window.
  A today member that failed to reach its own branch would compile clean and
  silently report all-time history, so today is handled first and the test
  asserts since is bounded rather than only checking the day count.
- The day overflow row now sums cost. Past 256 distinct provider/model pairs
  the tail collapses into one "other" row, and an unsummed aggregation looks
  correct in every breakdown below the cap. The regression test puts the only
  priced model in the tail and was driven red before it passed.
- 1d normalises to today at the parser instead of becoming a second union
  member, which would have needed its own cache slot and grid arm for nothing.

USAGE_RANGES and USAGE_SURFACES are exported so consumers stop re-declaring
the members in their own literals.

* feat(usage): filter /api/usage by provider and model

Narrowing usage to one provider previously meant fetching the whole window and
filtering client-side. --surface looked like it should help and does not: it
selects the client (codex/claude/grok), not the upstream provider, so
--surface grok answers a different question than the one being asked.

The filter is a projection over a finished summary, never a parameter to
summarizeUsage. That is not a style preference. The cache key is range:surface
and the warm loop writes every key on a miss, so a filtered summary that
reached the producer would be stored under the unfiltered key and the next
caller - the dashboard included - would be served one provider's totals as the
whole window. Keeping the filter outside the producer makes that
unrepresentable rather than merely discouraged.

The regression test for it was verified by falsification: projecting into the
cached value makes it fail, and it passes again when reverted.

Totals are recomputed from retained rows, which is exact for cost (combo cost
is attributed per attempt, so it partitions) but can overcount requests when a
combo request participates in several models. comboOverlap reports when that is
possible instead of leaving it silent. accounts is emptied under a filter
because account rows cannot be honestly re-partitioned by provider, and showing
whole-window account totals beside filtered model totals invites the wrong
reading.

The warm loop now iterates USAGE_RANGES/USAGE_SURFACES instead of its own
literals. A subset literal type-checks happily, which is why today would have
been silently unwarmed and never invalidated with its siblings. The cache-count
assertions in settings-stream-mode are derived from the same constants for the
same reason.

* feat(cli): print the usage cost breakdown instead of an item count

ocx usage rendered its payload through summaryLines(), a generic depth-1
flattener shared with storage/memory/debug/claude-inbound/injection. It stops
at depth 1 and renders any array as "N item(s)", so models, providers and
accounts printed as a row count and every per-entity cost the server had
already computed was discarded. The only cost a user could see was the
whole-window total across every provider, which is not the number anyone is
asking for.

usage now has its own renderer rather than a deeper shared one, because
deepening summaryLines() would change five unrelated commands. It follows the
existing house style: dynamic padEnd columns like formatAccountTable, plain
text, no ANSI.

Two wording decisions are load-bearing. A zero total is ambiguous between "no
spend" and "no price row matched", so unpriced and unmetered counts are shown
separately. And most traffic through this proxy is subscription or OAuth-plan
based where no per-request charge exists at all, so the disclaimer is not
decoration - a bare dollar figure would be read as a bill. Both borrow the
dashboard's existing wording so the two surfaces agree.

--provider and --model are registered in all three places the CLI needs
(the observe USAGE constant, the registry entry, and the help banner); the
banner line was also stale, omitting --surface and --json.

Live evidence in devlog 031: the question that started this unit now answers
in one command.

* docs: document the usage today window and provider filter

English carries the full explanation, including the distinction that keeps
catching people out: --surface selects the calling client, --provider selects
the upstream target serving the request. Locales get the flag list, which is
code-shaped and locale-independent, so they cannot contradict the English
source while awaiting translation.

Also states why a zero cost is not automatically free: requests with no
matching price row are reported as unpriced/unmetered rather than folded in.

* fix(usage): re-summarise filtered windows instead of projecting rows

Review found three defects that shared one cause: the projection operated on
breakdown rows, which have already lost the identity it needed.

- A provider or model living only past MAX_USAGE_MODEL_BREAKDOWN_ROWS is
  collapsed into a synthetic "other" row, so filtering for it reported
  matched:false and zero cost despite real usage.
- A provider row is a whole-provider aggregate. Under a model filter,
  providers[] kept the provider's other models while models[] and the totals
  excluded them - one response contradicting itself.
- A model row carries a single optional cost, so priced/unpriced could only be
  guessed per model rather than counted per request, and unmetered was always
  reported as zero.

Filtering now re-summarises from the entries the summary was built from. The
entries are already in hand on every path that filters, so the honest
computation is also the simpler one. Filtered requests skip the cache, since a
cached summary carries no entries and serving one would mean projecting over
collapsed rows again; the unfiltered cache stays warm either way.

Also: build the human report only when it will be printed. Arguments are
evaluated before the call, so passing it inline ran the renderer during --json
and let its assumptions touch a path meant to bypass it. And 1d now appears in
every synopsis that already listed today - the alias was accepted but
undocumented in all eight of them.

* fix(usage): filter combos by attempt, and scope matched to the window

Two more review findings, both reproduced before fixing.

Keeping a whole combo entry because one of its attempts matched dragged the
other attempts into the filtered totals. A two-attempt combo filtered to its
cheap model reported ~$0.368 instead of ~$0.008 - the expensive model's spend,
attributed to a model the user had explicitly filtered out. The predicate now
applies at attribution level and the entry is rewritten down to its matching
attempts, so filtered numbers mean what the flag says. Combo requests are still
counted once per participating model; that overlap is documented and is what
comboOverlap reports.

filter.matched was computed from entries scanned before the range and surface
predicates ran, so a match from an earlier day set matched:true for
--range today while the summary showed zero requests. Since the CLI uses that
flag to choose between a table and "no usage recorded", the message and the
numbers could disagree. It now derives from the projected summary.

Also adds --model to the top-level help synopsis, which listed only --provider.

* fix(usage): spend each day-attribution cost once

dayAttributionCosts keys by provider/model and holds the SUM of every attempt that
shares a key, but usageAttributions yields one entry per attempt. A retry onto the same
model therefore added that pair's total once per attempt, doubling days[].estimatedCostUsd
against summary.estimatedCostUsd. buildModels never had this bug because it adds each
attempt once.

Delete the key on read so the first attribution carries the group's cost and its siblings
get zero. The regression test uses two attempts on the SAME model, which is the case every
existing combo test misses -- they all use two different models.

* fix(vision): guard HTTP error body cancellation

* fix(usage): reject rows without provider labels

* fix(images): retain canonical interception for alias choices

* fix(xai): stop stripping web_search fields xAI accepts

`normalizeXaiResponsesWebSearch` deleted `user_location` and
`search_content_types` from every xAI web_search declaration. Both are
accepted by the upstream, so this was a silent capability loss on the
API-key path — a caller's location hint and content-type selection never
reached the model.

It also contradicted the sibling layer: `stripOpenAiOnlyWebSearchFields`
removes exactly the two fields xAI refuses and deliberately KEEPS
user_location/filters, with a probe note recording them as accepted
(tests/responses-routed-web-search-fields.test.ts). The two layers
disagreed about the same field, and the normalizer ran first, so it won.

Probed 2026-08-22, one field per request, against BOTH xAI destinations
(api.x.ai and cli-chat-proxy.grok.com), which behave identically:

  external_web_access   400 on EVERY value, including `true`
  search_context_size   400
  user_location         200
  search_content_types  200
  filters               200
  enable_image_search   200

So only the two refused fields are removed now. The image-search mapping
is kept: it compensates for nothing being deleted anymore, but dropping
it would be a separate behavior change.

Two assertions in responses-routed-web-search-fields.test.ts over-specified
the result as a bare `{type:"web_search"}` while that file's own probe note
says user_location is accepted; they now assert it is preserved.

Gate: 14246 pass / 5 fail, and all five also fail on untouched upstream/dev
(baseline: 6 fail, a superset). Zero regressions. The failing families
(CL-07, autostart shim, release helper, shellStreamExec) are flaky and
unrelated.

* fix(codex): preserve routed history provenance

* fix(codex): address history restore review findings

* test(xai): prove the capability backfill is causal on both destinations

The two assertions this branch changed both built an api.x.ai provider, where
the xAI normalizer strips the fatal fields before the capability gate runs. They
would have passed with the backfill broken, and never touched the OAuth CLI
destination the Responses opt-in actually targets.

Now the OAuth row resolves through resolveProviderTransport("xai", routed),
asserts it reaches cli-chat-proxy.grok.com, and checks the accepted fields
survive there; an unclassified control asserts the fatal fields are RETAINED
without classification, so a broken backfill fails.

* fix(cli): resolve the effort ladder the way the runtime resolves it

`ocx models` built `reasoningEfforts` from a bare per-model lookup falling back
to the provider-wide list. The catalog (`provider-fetch`) and the effort cap
(`effort-policy`) both go through `configuredReasoningEfforts`, which does three
more things: it returns `[]` for a `noReasoningModels` match, drops levels Codex
does not declare, and re-adds tiers a wire map proves the model emits.

Restating two of its five lines meant the command reported a ladder the proxy
strips and echoed junk as a supported level:

  noReasoningModels: ["model-b"]        ocx models ["low","medium","high"]
                                        runtime   []
  modelReasoningEfforts:
    model-c: ["high","bogus","low"]     ocx models ["high","bogus","low"]
                                        runtime   ["low","high"]

`ocx models` is what an operator reads to check what a config actually did, so a
row that disagrees with the proxy is the one thing it must not print.

This is the sibling of the modality fix in #2086, which routed the three maps
through `modelRecordValue` on the lines above but left this one a partial
re-implementation.

* release: v2.32.0

* release: v2.32.0-preview.20260824

* devlog: v2.32.1 hotfix train roadmap unit (260824)

Opens the docs-only cycle for the next release train. The planning note this
started from targeted v2.31.1; that baseline is void because v2.32.0 shipped
from main on 2026-08-24. This unit re-derives the baseline from live git state
and plans the train as v2.32.1, bugfix-only.

The first draft got the branch relationship wrong: it read a one-way
--is-ancestor result as divergence. An independent audit re-ran both directions
and dev turns out to be an ancestor of main, 0 ahead and 27 behind, with a
one-line tree delta. wp1 is therefore a fast-forward, not a backmerge, and the
correction is recorded in the document rather than quietly fixed.

Three audit rounds moved two other things. #2427 was reordered from first to
last: changing the test runner before the runtime fixes would make every later
failure ambiguous between a real regression and parallel-execution flakiness.
And #2472's regression got its own work-phase (wp9) once the audit pointed out
the plan had made it a mandatory gate while assigning nobody to write it.

Contents: 000 baseline/scope/roadmap, 001 verbatim reviewer-lane evidence, and
one diff-level decade doc per implementation phase (010 wp1, 020 wp3/#2483,
030 wp4/#2481, 040 wp5/#2473, 050 wp6/#2477, 060 wp7/#2476, 070 wp2/#2427,
080 wp8 freeze, 090 wp9/#2472).

No code changes. No promotion, tag, or publish.

* devlog: record wp1 delivery via PR #2487 and the two CI flakes

* fix(anthropic): classify capitalized/dotted Claude ids as adaptive thinking (#2483)

* fix(anthropic): classify capitalized/dotted Claude ids as adaptive thinking

claudeFamilyVersion only matched lowercase `claude-\<family>-\<major>-\<minor>`
ids. Vendor ids such as `Claude-Opus-4.8-joybuilder` failed both the
case-sensitive prefix match and the dotted minor parse (4.8 -> minor 0),
so usesAdaptiveThinking() returned false and the adapter sent the legacy
`thinking: {type: "enabled", budget_tokens}` wire shape to models that
reject it (Bedrock 400: "thinking.type.enabled is not supported for this
model. Use thinking.type.adaptive and output_config.effort").

Make the parser case-insensitive, accept `.` as a minor separator, and
lowercase the captured family before table lookup. Date-pinned ids
(claude-opus-4-20250514) and legacy families (opus <= 4.6) keep their
previous classification.

* test(anthropic): cover capitalized/dotted Claude ids in thinking wire-shape matrix

Regression for the family parser fix: Claude-Opus-4.8-joybuilder and
claude-opus-4.8-joybuilder must pick the adaptive wire shape, while
Claude-Opus-4.6-joybuilder (below the adaptive threshold) must stay on
the legacy thinking.enabled shape.

* fix(anthropic): reject a longer number, not any dot, in the family tail

The capitalization and dotted-minor repair is right, but widening the
tail from (?!\d) to (?![\d.]) to stop "claude-opus-4.20250514" also
rejected "claude-opus-4-8.1": the minor group matches "8", the tail sees
the following dot, the match is discarded, and the regex backtracks to a
major-only "4.0". That id parsed as Opus 4.8 before this PR, so it would
newly take the legacy thinking.enabled wire shape — the exact 400 this
change exists to prevent, reintroduced for a different id family.

A dotted suffix after a dashed minor is not a dotted minor. The tail's
job is to reject a longer NUMBER, which the original (?!\d) already did;
the dotted-minor support belongs entirely to the [.-] separator. Keeping
(?!\d) and adding only [.-] and /i covers every id the PR intended,
preserves every id the old regex classified correctly, and additionally
recovers "claude-opus-4.20250514" and "claude-opus-4.8.1", which the
wider tail turned into no match at all.

Tests: the adaptive matrix gains the dashed-capitalized and end-of-string
dotted cells so the capitalization and separator axes are covered
independently, plus "claude-opus-4-8.1" as the regression for the above.
The legacy matrix gains a capitalized date-pinned id, which previously
reached that branch by failing to parse rather than by parsing correctly.
The #545 explicit-disable matrix gains "Claude-Sonnet-5" — the only case
that exercises claudeFamilyVersion's second caller, where a miss is
invisible because the request simply goes out without the disable.

Verified red-then-green: with the original tail restored, only the
claude-opus-4-8.1 case fails (59 pass, 1 fail); with this correction,
60 pass, 0 fail. tsc --noEmit clean.

* fix(catalog): match selectedModels the way the canonical resolver matches it (#2481)

* fix(catalog): match selectedModels the way the canonical resolver matches it

`filterCatalogVisibleModels` built the per-provider allowlist as a plain
`Set(selectedModels)` and tested it with `allow.has(m.id)` — the native model id,
exactly. The canonical resolution of the same list keys it through the slug
equivalence:

  sync.ts:819-821   new Set([...models].map(m => slugEquivalenceKey(routedSlug(provider, m))))
  sync.ts:1039      selected === undefined || selected.has(slugEquivalenceKey(slug))

so the two disagree for any provider whose native ids contain a slash:

  stored "moonshotai/kimi-k3-free"   sync accepts=true   catalog filter accepts=true
  stored "moonshotai-kimi-k3-free"   sync accepts=true   catalog filter accepts=false

The second is the Codex-facing slug `routedSlug()` produces and the picker
displays, and `ocx models remove` already accepts it (tests/cli-models.test.ts:332,
"models remove accepts raw and encoded slash selectors"). An allowlist written
from what the user sees therefore blanked the provider's catalog silently, while
`routeModel` decoded the same string back and served the model happily.

Affects providers with slash-bearing native ids: openrouter, zenmux, nvidia,
together, fireworks.

The `disabledModels` loop three lines above is already tolerant of both forms via
`slugEquals`, and slug-codec.ts:20-21 states the rule this restores: "Config
comparisons are tolerant … so legacy raw values keep working regardless of which
form was stored."

* test(catalog): pin the lossy collision and record the rejected alternative

The key comparison is right for the reported bug, but it is lossy in a
way worth writing down: "a/b" and "a-b" collapse to one equivalence key,
so a provider publishing both spellings has them selected together. That
behavior now has tests asserting what the code actually does, rather than
being left for someone to discover from a support thread.

It also has a rejected alternative recorded next to it. Resolving each
selection against the provider's current rows looks stricter and is not:
the roster is an incomplete dictionary, so when live discovery omits
"a-b" but returns "a/b", an exact "a-b" selection resolves onto "a/b" and
reproduces the same over-grant. It would additionally make fresh
filtering disagree with the equivalence relation sync.ts applies when
merging the persisted catalog — two catalog stages with different rules
is the bug class this change removes.

The real fix is one selection resolver shared by filtering, persisted
sync, CLI removal, and routing, evaluated against a complete known-id
set, with a single ambiguity policy. That is an architecture change and
does not belong in a bugfix-only release; tracked as #2491.

Tests: 242 pass across selected-models, codex-catalog, slug-codec, and
cli-models. tsc --noEmit clean.

* fix(codex): keep oversized Responses turns off the WS transport (#2473)

* fix(codex): keep oversized Responses turns off the WS transport

The Codex backend closes the socket on any inbound message of 16 MiB or
more without sending a Responses terminal event, which reached clients as
a bare 502 upstream_server_error. Because the wrapper only fell back to
SSE when the *upgrade* failed, a thread that crossed the ceiling could
never recover: every retry resent the same oversized frame.

Measured against the live endpoint on 2026-08-23: 16,777,000 B completed,
16,777,300 B closed the socket in ~1s, reproducibly. The same body still
succeeds over HTTP SSE, so the limit belongs to this transport alone.

Size the `response.create` frame before dialing and take the SSE path when
it does not fit. Deciding before the socket opens is what keeps the resend
safe -- after open the caller already holds a streaming Response, and a
retry there could double-generate the turn.

Two supporting changes:

- Carry the WS close code and reason into the stream error. A 1009 was
  previously indistinguishable from a network drop, and nothing in
  usage.jsonl or /api/logs recorded the real cause.
- Apply the provider's `upstreamHttpVersion` pin to the SSE fallback. The
  fallback is a routine path now, and serving a turn over HTTP while
  silently dropping the operator's protocol pin is wrong.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* test(codex): pin the transport boundary at the adjacent byte

The sizing helper already had unit tests, but nothing proved the real
serialized frame routes correctly one byte on each side of the limit.
That gap matters because the request body is not the frame: `stream` is
deleted and `type` is added before sending, so padding sized against the
body sits eleven bytes away from what is actually transmitted. An
off-by-one would live exactly there and pass every existing test.

These two build padding so the serialized frame is exactly limit-1 and
exactly limit, then assert the whole path: one socket and one send of the
expected byte length under, zero sockets and one SSE call at it. Flipping
the gate from >= to > fails the second one, so it catches a real
off-by-one at the transport level rather than only in the helper.

Two comment corrections while here. The close-code comment claimed the
named 1009 message makes the failure diagnosable from the logs; it does
not. The eager relay turns any stream error into a generic
`upstream_reset` synthetic terminal without feeding it back through the
inspector, so `/api/logs` retains only `streamAborted`. The message
reaches the client and stops there, and the comment now says so rather
than promising observability the code does not deliver.

The margin comment described 64 KiB as absorbing a future append. There
is no append. It is a conservative cushion, and the useful thing to
record is what it actually covers: RFC 6455 framing is 14 bytes at this
payload size — an 8-byte extended length plus a 4-byte client mask — so
even a backend counting frame headers has ~65.5 KiB of room.

Tests: 59 pass, 1 skip across ws-upstream, sse-failed-tail, and
upstream-http-version. tsc --noEmit clean.

* fix(responses): honor tool_choice for namespace aliases (#2477)

* fix(responses): honor namespace tool choice

* fix(responses): match the tool kind, not just the name, when arming aliases

Narrowing the alias map by tool_choice was right, but the allowed_tools
branch matched entries by name alone. Entries there are typed
{type: z.string()} by the schema, so the accepted set is open-ended, and
a selector naming a different KIND of tool contributed a function name it
has nothing to do with. An upstream answering with that wire name then
had it restored into a namespaced client call the caller never selected.

Restricting the branch to function|custom closes that, and it has to be
an allowlist rather than a denylist: enumerating kinds to reject can
never be complete when the schema accepts any string, and a kind added
next year would arrive pre-authorized.

That left a narrower version of the same mismatch. The alias identity
carried only {namespace, name}, so the declared kind was gone by the time
tool_choice was compared: a tool declared function could be selected by a
custom selector, and vice versa, both schema-valid. A wire name says
which tool, not what kind of call may carry it. The identity now keeps
the kind it was declared with, and both selector branches require it to
agree.

Tests cover fourteen non-function kinds plus an unknown future one, each
asserting the alias map stays empty and an upstream call carrying that
wire name is left unrestored with no namespace injected. Positive
controls declare and select the same kind so the filter cannot pass by
being deny-all, and two cross-kind negatives cover both directions
through both the forced and allowed_tools shapes. The default cases —
absent, auto, required — are pinned as unrestricted, since narrowing
should apply only where the caller narrowed.

Verified red-then-green: reverting only the type filter fails fifteen
cases; reverting only the kind match fails the cross-kind pair.
189 pass across namespace-tool-compat, responses-parser,
openai-responses-passthrough, and responses-opaque-blob-recovery, plus 71

* fix(responses): stop rewriting an unchanged snapshot every two seconds (#2476)

* fix(responses): stop rewriting an unchanged snapshot every two seconds

`responses-state.json` is bounded at 24 MiB and rewritten whole on a fixed
2 s debounce, so under sustained traffic every cycle paid a complete
re-serialization plus an atomic replacement of a file nothing reads until
the next start.

Two narrow measures, both scoped to the write path:

- A flush that would reproduce the existing file byte-for-byte is
  skipped. A mutation does not always change what gets persisted —
  entries past the per-entry or total bound are dropped from the
  selection, and spill demotion moves bytes out of it. The comparison is
  a length plus a Bun.hash digest rather than the retained payload, which
  at the 24 MiB bound would double the snapshot's memory cost. The skip
  is conditional on the file still existing, so a snapshot deleted
  underneath the process is restored.
- The debounce scales with the size of the last snapshot written: base
  2 s below 1 MiB, linear above it, clamped at 30 s. The write rate is
  then roughly flat as the cache grows instead of growing with it.

Durability is unchanged for a graceful shutdown, which flushes; a longer
debounce only widens the window in which a hard kill loses the most
recent continuation entries, which are cache.

Journal / incremental store deliberately not attempted here.

Refs #2460

* docs(troubleshooting): say the debounce follows the last snapshot written

The section read as though the cadence tracked the pending snapshot. It
tracks the size of the last snapshot actually written, so a cache that
has only just grown still takes the short wait once. Review feedback on
#2476.

* fix(responses): verify the snapshot on disk before skipping a write

Skipping a byte-identical rewrite is the right fix for the amplification,
but the cached digest describes what this process last wrote, which is
not the same claim as what is on disk now. A second proxy sharing the
home, or anything that rewrites the file in place, leaves the digest
describing bytes that are gone.

That matters more than it sounds. Before the skip existed, every flush
rewrote the file and so repaired external damage silently. Skipping on
the digest alone turns a self-healing snapshot into a permanently corrupt
one, and nothing notices until the next restart fails to load the
continuation state. Replacing the file with different bytes of the same
length reproduces it: the digest still matches, the file still exists,
and the flush declines to repair.

The skip now verifies identity against the file itself. The cached digest
is keyed to the resolved write target, so a config-dir change or a
retargeted symlink is a miss rather than a false match, and the contents
are compared byte-for-byte before declining to write. Size is checked
first so the common mismatch costs a stat, any read failure answers "no"
and the caller rewrites, and the read only happens when the digest
already agreed. The amplification being fixed is the repeated 24 MiB
atomic replace, not the read that avoids it.

This also removes the need to trust Bun.hash for correctness. It stays a
cheap first filter, but a collision can no longer produce a false skip.

Tests: same-length external replacement must be rewritten, proven by
reverting only the disk check. The docs line claiming graceful shutdown
"always flushes" is corrected too — the flush is a disk write and can
fail like any other, and writeBoundedSnapshot swallows that into a
"failed" outcome the lifecycle warning cannot see.

124 pass across write-amplification and responses-state. tsc clean.

* fix(responses): close two post-merge review findings (#2500)

Two threads were opened on #2477 and #2476 shortly before each merged, so
neither was addressed. Both are real and both are one-line predicates.

A selector's namespace is either absent — meaning "unqualified, resolve
the bare name" — or a string naming the group. rewriteNamedSelector
treated every non-string value as absent, so {type:"function",
namespace:1, name:"safe"} took the unqualified path, resolved to a
namespace wire name, and authorized an alias the caller never qualified.
A wrong-but-valid namespace already failed closed; only malformed ones
slipped through. Present-and-invalid now returns the selector untouched.

The snapshot fast path compared content but not permissions. This file
holds persisted request and response bodies and is written owner-only,
and the unconditional rewrite used to restore that on every mutation.
Skipping on content alone let a broadened mode persist for the life of
the process — a durable privacy regression rather than a slow one. A
widened file is now treated as not matching, so the caller rewrites it
through the hardening path. POSIX-only check; Windows ACLs are
re-applied by that same write …
