The tests G added fold into existing ones as subtests (design 47 G §626, A-306: 171 tests down to 154, integration 9 down to 7). TestMeshWaitRefusesLoudlyAndNeverLoops runs its groups of one-second rows as parallel subtests, each on a runtime of its own, 15 s down to 5 s (A-311: the one-second floor of a wait's timeout stands, no clock is injected). The go.mod no longer requires meshconditionsclient, which no package loads (T4). Node names in the lines G adds are role names (T5). Builds: design 47 G §626, design 34 every-event §19, A-306, A-311; review round 2 findings T2, T3, T4, T5 Claude-Session: https://claude.ai/code/session_01NcbgfGKaxw984XyAPfLm4h
