Red first (K3-19 a). A NISO-STS delivery built with `okf build` put every
concept under a directory named for the delivery path's file name -- a UUID
that occurs 0 times in the document -- and every `sources` entry named that
file twice, while the document carries exactly one <std-ident> with a
<doc-number> and one <title-wrap>, neither of which this package read.
11 of the 14 tests are red: `extract.declared_identity` does not exist, and
the build still names the directory and the address title from the file.
The 3 that pass today pin the fallback layer that must survive the change: no
declaration keeps the file name, a declared title carrying a flow terminator
falls to the file name, and a name another document's file already holds is
not taken.
