words.py matched a retired word only when nothing followed it, so the
plural of every retired word passed. The pattern now takes s or es on the
last word; 14 uses in 9 documents are reworded, two of them 'the hosts'
for the node-engines.
ADR 0244 sorts the mesh's concepts into ten domains (ADR 0006's contexts
carry over as domains), keeps machine and node as distinct words, and
makes the glossary the authority with every retired word on its
replacement's Not: line. To-be 49 draws the domains; the glossary is
reorganised by them, its two contradictions removed and the missing
words added. words.py now fails on a retired word in running prose and
on a word defined twice, so the rule is enforced rather than believed;
the 63 documents it failed on are reworded here, and research 034 is
kept as the record of the words it studied.
