description: "Scores an agreement's clause coverage against a named clause taxonomy -- the oneSaaS 52-clause canonical set, the Common Paper Language Library, the GDPR Article 28 processor set, or a custom list. Reads a caller-declared present/modified/extra/missing status per clause and returns a coverage percentage, modification rate, and a maturity tier (minimal/partial/substantial/full). Extra clauses are tracked but excluded from the coverage denominator. This node reads the caller's own clause inventory -- it never vendors, assembles, or redistributes any third-party template body. Not legal advice and not a determination that any agreement is compliant. Zero network, zero PII."
