Gets the clauses as the document's own metadata records them, together with the playbook id
stored at check-in and the attachment's authorship. The clause library is NOT consulted: no
original clause entry is looked up, no {LibraryText} is returned, and no clause is dropped
for lacking library text — so this response includes clauses that {{attachmentId}/clauses}
omits. For the same reason a markup clause, which has no library entry to resolve an id from,
comes back with an empty {ClauseId}. Use {{attachmentId}/clauses} for the
library-reconciled view.
Returns 400 when attachmentId is missing. An unknown id returns 404 only where the
underlying fetch answers with nothing; on the Conga Platform the document provider raises an error
for an unknown id and that surfaces as 500 instead. An attachment that exists but carries no clause
metadata returns 200 with an empty clause list.
