ViDA Digital Reporting Requirements

Note (dated 2026-08-04): a chain composes independent computations performed in an analytical order. No step's output is carried into the next step by the execution model; each step computes from its own declared inputs. This is true of every chain on this site, including chains whose per-step copy below reads as a data handoff.

Question: Digital reporting of e-invoices arrives in 2030. Is the transaction data we exchange today already fit to report under it? Run the AINumbers MCP tool `run_chain` with {"chain":"vida-digital-reporting-requirements"} and read `art-161-vida-recapitulative-statement-migration-assessor.migration_ready`. Verify: call `verify_execution_hash` (https://mcp.ainumbers.co/mcp) with `claimed_hash` set to `composite_execution_hash` and the full `composite_artifact`. Ledger, for a human re-check: https://ledger.ainumbers.co/ PII rule: send synthetic or anonymised inputs only. The MCP server runs these kernels and logs no payloads.
