correct the field name this doc got wrong, and mark B1/B3 done

22bcd7d fixed both, and found the fix this document suggested was written against a field that does not
exist: opencode 1.17.9 returns `directory` at the top level, not `location.directory`, and sends no
`metadata` at all. The type declared two fields the server never returns, which is the single cause of
both defects.

Worth recording rather than quietly editing, because it generalises: the surveys behind this document
read types and call sites, not a running server, so every field name in it is a hypothesis. The
'check the installed version first' warning was the load-bearing part of the handover, not boilerplate.
