Background (round 5, snapshot10f): 7/7 pass.
d1 TaskStop stopped only its target; d4 watcher process group cleaned at exit; d5 TaskList listed exactly the 8 shells (round-3 fix holds), #9 got the 8-running limit error, #10 repeat refused by failure budget ('Not run: this exact Bash call failed…', by design); d6 'Stopped before this turn finished.' holds, resume did not redo work; d7 SIGKILL watchdog took the server group down in 1.1 s, stale running record and dead lock handled on next start.
Reviewer's own lsof/ps sweep: no listeners or orphans from these scenarios. All costs match.
Notes: d2 exit code still stated three times (correct, cosmetic). d6 model used 'cmd &' inside Bash; G-Code adopted and cleaned it. d3 TaskOutput only read after completion (model timing).
