callerOn reads a caller only under the call kind, so a tool subscription ending in a wildcard never yields one. A caller-named call that reached nobody is said once per subject before it is asked on the old subject, so a runtime or grant that drifted behind is seen rather than a quiet unproven. The caller tests wait for their bundle's exit, which reads the launcher's restart pauses another test sets.
