fix(responses,codex): stop charging a send that never happened, and let a reauthenticated account back in - #4690
Conversation
Pins the frozen candidate 2702911 and enumerates all nine commits of the range, so "every commit was audited" is checkable. Restates the release sequence in the order MAINTAINERS.md and the release workflow gates actually force — the dev version pre-move comes first — and adds the preview promotion. Records the landed #4683 evidence: head d8ef6ee, CI run 34935526979, squash 2702911.
Nineteen slices over the true 59-commit range, run on gpt-5.6-sol and paired onto xai/grok-4.6 after sol began refusing parallel fan-out. Twelve god-file decompositions clean; two real regressions in the #4546 work; five risks accepted as non-regressions. Includes the per-commit coverage map and the shallow-clone lesson that corrected the range.

Replace this module-relative new URL(..., import.meta.url) lookup with repoPath() from tests/helpers/repo-root.ts; the other new oracle in tests/codex-integration/codex-pool-refresh-backoff.test.ts uses the same unsupported pattern. These tests read repository source as data, so tying resolution to each test file's current nesting makes a later test move or modularization break the oracle instead of preserving its repository-root target.

Make the corrected 59-commit delta the single release-gate scope.
The documents use conflicting scopes. 000_roadmap.md calls the nine commits the frozen range and makes verdicts for those nine the completion criterion. 020_regression_audit.md later states that the nine commits are only the tail of the 59-commit delta, records nineteen slices covering every commit, and describes criterion 2 as covering 1cc89cf88c..2702911708. The full-delta audit evidence exists, but the roadmap wording still allows the gate to be satisfied by a nine-commit review.
Define the frozen range as 1cc89cf88c..2702911708, require a verdict for every commit in that range, and label the nine-commit table as the tail or release-focus subset. Update the Round 2 introduction to use the corrected 59-commit scope.

Remove the superseded cooldown-risk claim.
This text says that a stale refresh flight can re-open the cooldown and that generation fencing is deferred. Lines 306-308 describe the implemented fence, and src/codex/pool-refresh-backoff.ts drops failures with a stale fence. Replace this statement with the final behavior.

…et a reauthenticated account back in The 2.56.0 regression audit found two defects in the #4546 work. Neither is in any of the twelve god-file decompositions the audit spent most of its budget on. The generic-OAuth 429 ladder reserves a hop before it knows whether a rotation is possible, and the reservation is the charge. Its two explicit early-outs released the permit; its catch did not, so a throw from the snapshot fetch or from credential application spent an allowance on a send that never left the process, and a later recovery in the same request was refused because of it. adapter-dispatch now confirms with use() immediately before the rebuild that spends the permit and releases in its catch -- release() is a no-op once used, so one catch covers both halves. adapter-continuation only releases, because its replay is the next loop iteration and confirming before continue would charge a hop that never ran. run-turn-execution already had this shape. The pool refresh cooldown is learned about a credential but keyed by account id alone, so a successful reauthentication inherited the dead credential's 15-60s quarantine: selection kept excluding an account that had just been authenticated, and with a healthy sibling the thread detoured and lost its warm cache and continuation. login-flow now clears the refresh-failure record where it replaces the credential, beside the quota and needs-reauth clears already there. Generation-fenced keying stays open and is noted. The file-size ratchet also gets its six former god-files back at their current sizes. They were dropped from the cap list when they fell under the 2,000-line threshold, which left the files the decomposition programme exists to shrink as the only ones free to grow back.

Maintainer self-integration on Head This landed after three review rounds on the same fix, each of which moved the permit confirmation closer to the wire: from the The cooldown fix went the same way: clearing on credential replacement was mitigation, so a per-account fence now drops a refresh failure that reports on a grant which has since been replaced. An interdiff audit of this exact tree confirmed the fence, verified the six restored ratchet caps equal their real line counts, and found no new cycle or initialization-order change.

Requesting changes on exact head 26b3ff244434846149b560e28f7441afae529564. The dispatch-permit repair and per-account reauthentication fence are sound, but the same stale-flight boundary is still open on the bulk reset path.
clearThreadAccountMap() calls clearAllCodexPoolRefreshFailures() when the routing roster/runtime state is discarded. The new clearAllCodexPoolRefreshFailures() clears only backoffByAccount; it does not advance or replace fenceByAccount. A refresh flight that captured fence 0 before the clear can therefore fail afterwards, still compare equal to the current fence 0, and recreate cooldown state for the roster/credential generation that was just discarded. This is the bulk form of the exact race the PR fixes for one reauthenticated account.
Please make the bulk clear invalidate every previously captured fence as well. A process-wide epoch combined with the per-account generation, or a monotonic default fence plus per-account overrides, avoids needing to know every in-flight account and can also keep the per-account map bounded when the whole roster is reset. Add a regression that captures a fence, records/clears through clearAllCodexPoolRefreshFailures(), then proves a late failure carrying the old fence cannot reopen cooling while a newly captured fence still can.
The exact-head hosted matrix is otherwise green except for the still-running macOS shard; that CI cannot establish this missing bulk invalidation because no current test exercises it.
