Turns one permissioned-validator event on an Evergreen L1 — a validator add, remove, or weight change — into change-control evidence in the shape the SOX/ICFR control family already uses: who authorized it, the weight delta and its share-of-total effect, and whether the caller's own declared approval-quorum policy was met. The event is transcribed by the caller; this node observes no chain and makes no RPC call. Not a §27 dual-control threshold evaluator — see ART-503 for counting distinct approvers against a certification threshold.
Copy this paragraph into Claude, OpenClaw, or any MCP-aware agent to run this exact tool, with this sample, and verify the artifact.
Run the AINumbers MCP tool `build_validator_change_control_receipt`. Task: Turn one permissioned-validator event on an Avalanche Evergreen L1 -- a validator add, remove, or weight change -- into change-control evidence in the shape the SOX/ICFR control family already uses: the authorization chain of named identities, the weight delta and its share-of-total effect against a caller-supplied total network stake, and a quorum verdict comparing the caller's declared approval-quorum policy against what the caller states was achieved, plus a structural exceptions list (nonzero prior weight on an add, nonzero posterior weight on a remove, no delta on a weight change, an unauthorized change, an achieved-quorum count exceeding the number of named authorizers).
Call it with arguments: {"policy_parameters":{"validator_ref":"VAL-07","change_type":"weight_change","prior_weight":1200,"posterior_weight":1500,"total_stake_weight":50000,"authorizing_identities":["ID-A","ID-B","ID-C"],"quorum_required":3,"quorum_achieved":3,"effective_epoch":"epoch-4821","as_of":"2026-07-30"}}
Verify before trusting: call `verify_execution_hash` on mcp.ainumbers.co (https://mcp.ainumbers.co/mcp) with the parameter `claimed_hash` set to the returned `execution_hash`, passing the full artifact the run returned (the object containing `policy_parameters` + `output_payload` + `execution_hash`; equivalently `policy_parameters` + `output_payload` with `claimed_hash`), not the bare hash string.
