The handoff and the two stopped rows blamed an environment fsync stall.
The cause was macOS refusing socket options after the peer closes, in
loopd and in the brokerd test client. The handoff now opens with the
resolution, the log gets a review note (the stopped rows are kept as
written), and the lessons gain I13 (measure what you blame, and name
the machine) and T18 (the gate must pass on Talos and on the Mac).
