Summary

fix: resolve #2807 — Possible flaky test in Endo

Problem

Severity: Medium | File: packages/ses/test/test-importNow.js

Tests that verify importNow behavior may be asserting on ordering that isn't guaranteed by the implementation, or may be passing locally due to favorable timing but failing in CI where execution timing varies.

Solution

Review tests that involve multiple importNow calls or check execution order. Ensure tests properly await all async operations before asserting. Add explicit synchronization points where needed. Consider using a deterministic test helper that waits for all queued jobs to complete before checking results. If testing ordering, ensure the test explicitly sets up the scenario rather than relying on implicit timing.

Changes

• packages/ses/test/test-importNow.js (new)
• packages/ses/src/jobQueue.js (new)

Testing

• Existing tests pass
• Manual review completed
• No new warnings/errors introduced
