# Hyper run — fresh-verifier verdict

Status: **PASS against the final contract**

No critical `FAIL` or `UNKNOWN` remained after four falsification passes.

| Criterion | Result |
| --- | --- |
| Legacy no-options sequential path and two-argument callback | PASS |
| Explicit `null` and invalid option rejection before work | PASS |
| Logical concurrency, ordering, retries, timeout, and abort | PASS |
| Hostile and late rejection handling in strict mode | PASS |
| Abort/timeout tie behavior and single settlement | PASS |
| Cooperative-cancellation limitation documented | PASS |
| Fresh counterexample search | PASS |

The final verifier also ran focused probes for both timeout/abort orderings. No
reproducible regression or missing critical criterion was found.

Residual risk: JavaScript work that ignores its aborted signal may continue
physically. This is an accepted and documented limit of the final contract.
