The single- and multi-level suspend/restore tests gated their slow leaf tool on a manual release channel closed 50ms after cancel(). That sleep was a guess at how long the suspend signal takes to reach the running sub-agent, so the post-tool turn boundary could observe the release before cancellation and complete the run instead of checkpointing, making the assertions timing-dependent. Expose the per-run suspend signal through SuspendSignalFrom in an export_test shim and have the leaf tools block on it directly. The tool now returns only once the graceful-suspend signal has actually propagated to its agent, so suspension is observed deterministically without sleeps or release channels.
