**Fix**: children now post their result/exception to the mailbox directly upon completion, using an atomic pending counter to correctly sequence the end-of-stream sentinel — guaranteeing true completion-order delivery.
**Validation**: Added 2 regression tests mirroring the issue's gated repro; full suite passes 513/513 (511 existing + 2 new).
**Actions taken**:
- Created draft PR with the fix, tests, and release notes entry
