Climate Scenario Stress (NGFS / Fit-for-55)

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.

Apply an NGFS / Fit-for-55 scenario path to an exposure set -> stress-adjusted metrics (ART-76) -> audit receipt (cry-05). The bank/insurer climate-risk computation a supervisor re-verifies. Scenario paths are versioned reference data, not the suite financial-shock stress parameters.

Question: Our climate stress runs on the orderly NGFS path. What carbon price does the 2030 horizon assume? Run the AINumbers MCP tool `run_chain` with {"chain":"climate-scenario"} and read `art-76-climate-scenario-applicator.carbon_price_assumption`. Re-run with `inputs` for `art-76-climate-scenario-applicator`, reusing the values that result echoed, with `scenario` changed so the scenario family is NGFS-disorderly. 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.
