`disposeShutdownHandler()` unregistered the shutdown flush but left the debounced save timer armed. That timer keeps its own reference to the manager, so a disposed instance still wrote 500ms later. The write is not additive. `saveToDisk()` builds the payload from this manager's account snapshot and adopts only newer credentials and longer rate-limit blocks from disk; accounts the snapshot does not contain are not carried over. A disposed manager firing after its replacement has loaded therefore removes every account the replacement knows about and it does not. The suite reaches that state on its own. `test/chaos/` drives a real AccountManager through the request-path 401 handler, which ends in `saveToDiskDebounced()`, then calls `disposeShutdownHandler()` and returns. Under real timers the worker outlives the debounce window, and the two-account fixture lands on the developer's own account pool, replacing whatever was there. Recovering it needs a backup. Cancel rather than flush: what a cancelled save drops is a rotation cursor or a `lastUsed` stamp, both already last-writer-wins and both rediscovered on the next request. The timer is cleared before the handler guard, because the handler is one-shot and clears its own slot when it runs, so a manager whose shutdown flush already fired can still hold an armed timer.

This suite drives a real AccountManager through the request-path 401 handler, and that handler ends in `saveToDiskDebounced()`. With no storage override the write target is the developer's own `~/.opencode/oc-codex-multi-auth-accounts.json`, and the payload is this file's two-account fixture. Point it at a pid-scoped temp file for the duration, the way `rotation-integration.test.ts` and `chaos/storage-faults.test.ts` already do, and remove it afterwards. The preceding commit stops a disposed manager from writing at all, which closes the path this suite happened to reach. The override is the layer that does not depend on a manager being disposed in time: any future scenario here that saves while the suite is running writes to the temp file rather than to a real account pool.

Fence a debounce callback that is already waiting on pendingSave.
Line 318 only cancels an armed timer. If the callback has already run and is awaiting pendingSave at line 229, saveDebounceTimer is already null. Disposal then returns, and the callback starts saveToDisk() after the earlier save resolves.
That later save still writes the disposed manager’s account membership snapshot. It can delete accounts written by a successor manager. Add a disposal generation token. Capture it when scheduling the debounce. Check it again after awaiting pendingSave and before starting saveToDisk(). Add a regression test that holds pendingSave past the debounce interval, disposes the manager, then releases it.

Use Vitest globals without explicit imports.
The repository guideline for test/**/*.test.ts requires using the configured beforeAll and afterAll globals rather than importing them explicitly. Apply this consistently in this file and test/accounts-dispose-cancels-save.test.ts.

Await in-flight debounced saves before removing TEST_STORAGE_PATH. disposeShutdownHandler() clears the timer but does not await pendingSave. A started transaction can finish after afterAll unlinks the file and recreate it. Await manager.flushPendingSave() before disposal and cleanup for each manager.

Pull request overview
Prevents disposed AccountManager instances from persisting stale in-memory snapshots to disk and makes the 401 stress suite use an isolated, pid-scoped temp storage file to avoid clobbering real developer account pools during tests.
Changes:
- Cancel pending debounced saves when
disposeShutdownHandler()runs to prevent late writes from disposed managers. - Isolate
auth-invalidated-401-stressaccount storage via a per-suite temp file override. - Add a regression test to verify disposed managers cannot overwrite on-disk accounts after the debounce window.

Summary
disposeShutdownHandler()now clears the pending debounce timer as well as unregistering the shutdown flush. It previously did only the latter, so a manager that had been disposed still fired its queuedsaveToDisk()up to 500ms later.test/chaos/auth-invalidated-401-stress.test.tspoints account storage at a pid-scoped temp file for the duration of the suite, the wayrotation-integration.test.tsandchaos/storage-faults.test.tsalready do.npm testcould overwrite the contributor's own~/.opencode/oc-codex-multi-auth-accounts.jsonwith a test fixture, deleting real accounts and their refresh tokens. I hit this: a six-account pool was replaced by the two-account fixture from the 401 stress suite.saveToDisktakes account membership from the in-memory snapshot wholesale. It adopts newer credentials and longer rate-limit blocks from disk, but it never adopts disk accounts the snapshot lacks. A disposed manager firing late therefore deletes every account its successor has loaded or added since.AccountManageris replaced while a save is queued: the outgoing instance's snapshot lands on top of its successor's. Cancelling on dispose drops a rotation orlastUsedstamp instead, which is already last-writer-wins and is rediscovered on the next request.The two commits are independent layers. The first stops a disposed manager from writing at all. The second does not depend on a manager being disposed in time, so any future scenario in that suite writes to the temp file rather than to a real account pool.

lib/foo.ts:123. confirm regression tests + windows concurrency/token redaction coverage.Greptile Summary
this pr cancels queued persistence when an account manager is disposed and isolates the 401 stress suite in temporary storage. the production fix has focused vitest coverage, but the stress-suite teardown still exposes a concurrency and token-safety path when a test fails.
Confidence Score: 3/5
this pr is not safe to merge until the stress suite disposes all managers before restoring the real account storage path.
an assertion failure in either real-timer scenario can bypass inline disposal, allowing queued fixture persistence to run after teardown restores the developer's account path and overwrite sensitive refresh-token state.
Files Needing Attention: test/chaos/auth-invalidated-401-stress.test.ts
Security Review
a failed real-timer stress test can skip inline manager disposal, after which suite teardown restores the user storage path while a stale save remains queued. that save can overwrite the real account pool and refresh tokens; the same risk applies on windows because the storage-path reset occurs independently of whether temporary-file cleanup succeeds.
