An abort or a timeout kills only the local ssh. A non-pty sshd command gets no SIGHUP, so the remote
add can still write its line after the undo's remove. The broker now marks install done only after
`await install(...)` returns. When it never returned, the undo records hostLineLeft with the tag, so
grant.failed and status name the line, hosts.remove refuses until `mosaic hosts sweep` clears it.
The :432 test comment now matches. Row a's enroll does no remote add, so it has no such race.
Candidate gizmoduck/row249-on-8a04 05595794b (Gizmoduck), manifest 3a969bb136bc, approved by
Duckworth in round 1 (rev 2889-2890 request c30068, verdict c30070). Gate on Sage's slot 14:53Z
(sage-2026): grant-executor.test.mjs whole 39/0 and bus 598/0 with no stub left, and C1, which
drops the `if (!installed)` branch, fails G8 and both G23 tests. Webby's N1 on X5 `sleep 30` is
deferred by Duckworth (DEFERRED.md).
