Row 93 follow-up: SIGTERM then SIGKILL for host git, rollback-failed,
a total body deadline, fetch-aborted for a reviewer gone mid-fetch,
working refs first in have, and tests for five untested refusals.
Dewey approved in 28226 and Sage in 28225; Sage's full gate passed
16:57:32-17:01:32Z. The host side is live at the next bus restart.
