EU Green Bond Factsheet & Allocation Conformance

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.

EuGB factsheet (Annex I) + allocation report (Annex II) completeness + proceeds-alignment validation (ART-75) -> use-of-proceeds Taxonomy alignment cross-check (ART-73) -> Merkle integrity over the bond evidence set (cry-04). The issuer-to-external-reviewer green-bond conformance pack. Decision-support draft, not a reviewer attestation.

Question: The allocation report landed this morning. With it on file, does the Annex II leg of our European green bond pack finally read complete? Run the AINumbers MCP tool `run_chain` with {"chain":"eugb-conformance"} and read `art-75-eugb-factsheet-validator.annex_ii_status`. Re-run with `inputs` for `art-75-eugb-factsheet-validator`, reusing the values that result echoed, with `allocation_report` set to "complete". Compare the same field. 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.
