Robinhood Chain Collateral Haircut

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.

Gated three-step chain for accepting Robinhood Chain stock tokens as collateral: tokenized-collateral eligibility, base repo haircut, then the feed-staleness / sequencer-downtime / underlying-halt haircut layer. Gate on liquidation_risk: blocked halts the chain, default proceeds to the adjusted collateral value.

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: Our stock tokens sit in a collateral pool. Is the price feed fresh enough to keep the base haircut?
Run the AINumbers MCP tool `run_chain` with {"chain":"rhc-collateral-haircut"} and read `art-320-rhc-collateral-haircut.liquidation_risk`.
Re-run with `inputs` for `art-320-rhc-collateral-haircut`, reusing the values that result echoed, with `current_time` 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.
