Sage gate rerun on f63c965f9 plus build.patch: every package suite and
every scripts/test-*.sh green (cli 168, harness 73, test-release 14).
readHostState now treats a host.json that vanishes mid-read as no host
for stopHost and hostStatus too (Dewey note b); Sage accepts it as
correct. Nothing goes live until a re-pin under Mos's go.
