Taxonomy KPI & Green Asset Ratio

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.

Activity alignment (ART-73) -> entity revenue/CapEx/OpEx KPIs + Green Asset Ratio for financials (ART-74) -> audit receipt (cry-05). Rolls activity-level alignment into the entity disclosure KPIs an issuer/bank reports to investors and supervisors.

Question: As a credit institution we owe a green asset ratio. Does the aggregator produce one from these activities? Run the AINumbers MCP tool `run_chain` with {"chain":"taxonomy-kpi"} and read `art-74-taxonomy-kpi-gar-aggregator.green_asset_ratio`. Re-run with `inputs` for `art-74-taxonomy-kpi-gar-aggregator`, reusing the values that result echoed, with `entity_type` set to "credit-institution". 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.
