Sorry, something went wrong.
FieldApi and FormGroupApi already drop in-flight async results after a newer run aborts them. FormApi was missing that check, so a slower previous validator could overwrite newer valid state.
WalkthroughForm-level async validation now ignores results from aborted validation runs. A regression test verifies that a slower invalid validation cannot restore errors after a newer valid validation succeeds. A patch changeset documents the fix. ChangesStale async validation handling
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to a0441 The change prevents stale form-level async validation results from overwriting newer valid state. The remaining risk is limited to test cleanup, since fake timers could leak into later tests if this test fails; owner follow-up is recommended, but this does not block the production fix.

Restore fake timers in a finally block.
If an assertion or await fails, later tests can inherit fake timers because no shared timer cleanup runs.

Changes
Fixes #2346
FieldApi and FormGroupApi already drop in-flight async validation after a newer run aborts the previous AbortController. FormApi only checked the signal before starting the validator, not after it resolved.
That matters for form-level onChangeAsync validators that cannot observe the signal (including Standard Schema / Zod async refinements). A slower previous run can still apply its result and restore an error after a newer validation has already accepted the current value.
The check is the same one those sibling APIs already use: if controller.signal.aborted after the validator settles, resolve without writing errorMap.
Reproduced with a form-level async validator: slow-invalid sleeps 2000ms and returns an error, then the value becomes valid (50ms). After the slow run finishes, the form was left with Stale validation result. With this change it stays valid.
Checklist
Local verification: vitest for packages/form-core/tests/FormApi.spec.ts (150/150 passing), including a new regression that fails on main and passes with this change.
