📝 WalkthroughWalkthroughOAuth login flows now reject superseded credential commits at the store boundary. Kiro replacement flows remain blocked while a canceled external CLI login settles. Regression tests cover XAI credential ownership and Kiro lifecycle ordering. ChangesOAuth supersession handling
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The change prevents cancelled logins from overwriting newer credentials, but the reauthentication path lacks a focused regression test for that behavior. The PR is mergeable with explicit owner awareness or follow-up because a narrow correctness regression could otherwise go undetected. Possibly related PRs

Add a superseded reauthentication regression test.
Lines 1177-1179 use saveAccountCredential, but tests/oauth-public-surface.test.ts lines 451-510 only cover the normal saveCredential path. A forwarding or ownership-check regression in reauthentication can therefore pass the new test suite while stale credentials overwrite the selected account.
Add a test that creates an existing account, blocks the store queue, starts and cancels a reauthentication flow, completes a replacement flow, and verifies that only the current flow updates that account.
As per path instructions, tests/** requires focused regression coverage for changed shared behavior. The PR objective also requires regression coverage for superseded reauthentication commits.

The superseded-login commit guard is a security-boundary change, so I cannot approve it on a stale head. The current branch is 16 commits behind dev (caf20353f), and its existing validation predates the current OAuth/store integration state.
Please rebase the focused three-file change onto the latest dev, rerun the OAuth race/public-surface regressions and full exact-head CI, then re-request the required security review. I will review the resulting credential generation and commit boundary rather than approve an obsolete diff.
A cancelled login could still persist its credential after a newer flow had taken ownership of the provider, so the newer login's token was silently replaced by the one the user had already abandoned. Check ownership at the synchronous persist boundary rather than before the work: mutateStore takes an assertBeforePersist hook that runs inside the file lock, after fn(store) and before persist(). An in-memory mutation from a superseded flow is therefore discarded rather than written, which is the only placement that cannot lose a race. Ownership is identity-checked against the flow's own AbortController, so a newer login replacing the entry is what invalidates the older one - not a timestamp or a flag either side could observe stale. Kiro replacements additionally wait for a cancelled CLI flow to finish rolling back before a new login may start. Carries @Ingwannu's #2053 unchanged. Closes #2053

Summary
A cancelled login could still persist its credential after a newer flow had taken ownership of the provider, so the newer login's token was silently replaced by the one the user had already abandoned.
Credit: @Ingwannu's #2053, carried unchanged.
Ownership is checked at the synchronous persist boundary rather than before the work:
mutateStoretakes anassertBeforePersisthook that runs inside the file lock, afterfn(store)and beforepersist(store). An in-memory mutation from a superseded flow is discarded rather than written — the only placement that cannot lose the race, since the in-memory object is thrown away when persist is skipped.Ownership is identity-checked against the flow's own
AbortController(loginAbort.get(provider) !== abort), so a newer login replacing the entry is what invalidates the older one. Not a timestamp, not a flag either side could read stale.Kiro replacements additionally wait for a cancelled CLI flow to finish rolling back before a new login may start.
Verification
src/oauth/fails 2 tests, including the ownership round-trip that queues a blockingmutateStore, starts flow 1, cancels it, starts flow 2, and proves onlyaccess-2/account-2is stored.bun test --isolate tests— 13,536 pass, 0 fail, 10 skip (855 files).bun test --isolate tests/oauth-public-surface.test.ts tests/codex-auth-context.test.ts— 61 pass, 0 fail.bun run typecheck— clean.bun run privacy:scan— passed.Two things a reviewer should check rather than take on faith
The reauth path is wired but not covered. #2053's description claims reauth coverage; the diff wires
saveAccountCredential(..., assertBeforePersist)but adds no reauth-specific test. The wiring is correct as far as I can read it, and I did not add a test I could not make meaningfully fail — but it is untested, and I would rather say so than let the claim stand.OAuthLoginSupersededErroris not in the public error allowlist, so it projects to the generic auth-failure string. That is the safe direction (no internal detail leaks), but it means a user who hits this sees a generic message rather than "your earlier login was superseded".A never-finishing Kiro rollback blocks all replacements, by design. That is a deliberate trade — better than racing — but it is a liveness property worth an explicit second opinion.
