  "display_name": "GloBE Information Return (GIR) Composer",
  "tool_version": "1.0.0",
  "mandate_type": "compliance_control",
  "purpose": "Assembles the OECD GloBE Information Return (GIR) data model for one MNE group / fiscal year by combining the outputs of art-454 (jurisdictional ETR), art-455 (SBIE / top-up), and art-456 (transitional safe harbour tests) into the GIR's jurisdictional-summary shape: per-jurisdiction ETR, SBIE, top-up tax, safe-harbour status, and the constituent-entity allocation split. Exports in two forms: an OECD GIR XML rendering (schema version pinned as a versioned policy_parameters input -- this tool does not chase draft schema revisions) and a form-shaped JSON mirror, both carrying the composed execution_hash in their metadata. Every jurisdiction row where safe_harbour_met is true is composed with top-up forced to zero (deemed_zero_topup), consistent with art-456; jurisdictions with no safe-harbour test result compose the raw art-454/455 top-up figures unchanged. This tool assembles and formats only -- it recomputes nothing upstream (ETR, SBIE, and safe-harbour verdicts are trusted inputs from their own nodes) and its XML/JSON export is explicitly marked NOT-SUBMITTABLE, since national filing gateways vary in accepted schema version and transport. Pure data assembly and templating. NaN-safe. Zero network, zero PII.",
