Estimated code review effort: 4 (Complex) | ~45 minutes Mergeability Score: 🟡 Moderate · up to Mount-time validation can let rejected promises escape without a handler, potentially causing unhandled promise rejections and incomplete cleanup. Merge should wait until rejection handling and guaranteed cleanup are added; the other items are bounded follow-ups. Sequence Diagram(s)sequenceDiagram

failfor the debounced error path.Lines 420-425 and lines 454-459 implement the same thrown-error handling: log the error, then settle a

In `@packages/form-core/src/validation/mount.lib.ts`:
- Around line 98-142: Update executeMountValidator so rejected promises from
both parseStandardSchema and asynchronous validator.run are caught, logged, and
converted to createEmptyMountValidationResult<TResult>(). Ensure cleanup always
runs through finally for these asynchronous paths, while preserving the existing
abort-result handling.
