Robinhood Chain Valuation Lint

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.

Single-step chain linting a Robinhood Chain stock-token USD valuation expression for the corporate-action double-count bug against the Chainlink 8-decimal feed.

Ask your agent

Copy this paragraph into Claude, OpenClaw, or any MCP-aware agent to run this whole workflow on the server and check one field that answers a real question.

Question: The desk priced a balance by multiplying the UI rate once more on top of the feed. Did that double-count the multiplier?
Run the AINumbers MCP tool `run_chain` with {"chain":"rhc-valuation-lint"} and read `art-319-rhc-valuation-linter.verdict`.
Re-run with `inputs` for `art-319-rhc-valuation-linter`, reusing the values that result echoed, with `computed_usd_value_under_test` set to 5000. 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.
