fix: pre-landing review fixes (pass 2)

An unclosed receipt fence makes the body from that line on one section
the merge never matches, so posted leading prose cannot replace it and a
closed receipt before it stays a receipt; the by-tree pregate mirror must
hold the tests stage (what --stage tests --remote writes) rather than
every check; empty sha/tree strings in a train note are not evidence;
(v1.2.3-rc1 #301) is a version word, not a repository.
