nx_tmplstale_lib.nx -- THE CLERK DESK: template registry, document lineage and TEMPLATE STALENESS over nx_docgen_lib (LP6 dg_tmpl_list / LP7 dg_assemble_lineage / LP8 dg_tmpl_stale on /compare/legalpractice). The gap this closes: nx_docgen stores clauses and templates on the immutable plane and assembles a content-addressed document, but NOTHING records which clause TEXT a document was built from, so a revised clause silently leaves every earlier engagement letter and every template that references it out of date. Here every template put snapshots the CID of each clause it references, and every assembly writes a LINEAGE record (template, document CID, clause CIDs). Staleness is then a pure comparison: current clause CID != recorded CID names the stale template or document. The output is a WORKLIST (every stale row named), never a count; a listing that would not fit its buffer REFUSES (-1) rather than truncating, because a short worklist reads as a finished desk. license_tier: ORIGINAL
