Private-Input Sanctions Screen

Screens a privately held party/transfer list against a pinned OFAC-SDN-style list version and emits only the verdict — screened, hit count, clean flag — without disclosing the list. Carries an OCG Standard §25 ocg-private-input@1 declaration: the party list is committed via sha256-salted@1, never present in the clear. Private-input variant of screen_tip20_transfer_batch (art-38) — use that public-input kernel when disclosure of the party list is acceptable; use this one when it is not.

🔒 All inputs are processed locally in your browser. No data is transmitted. Do not enter real personal data — use synthetic or anonymised inputs only. The screened party list stays a private witness — only a salted commitment and the screening verdict ever leave this page.
Private Witness (never leaves this page in the clear)
The private input. Only a sha256-salted@1 commitment to this list is included in the exported artifact — never the names themselves.
Fresh CSPRNG salt per screening run (SPEC.md §25.1). Never reused, never included in the artifact.
Public Inputs
Pinned list version + citation (public).
Case-insensitive substring matching (public config).

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 `screen_sanctions_private`. Task: Screen a privately held party/transfer list against a pinned OFAC-SDN-style list version and emits a public verdict (screened, hit count, clean flag) without disclosing the party list.
Call it with arguments: {"policy_parameters":{"parties":[{"name":"Example Shipping Co"}],"salt":"1111111111111111111111111111111111111111111111111111111111111111"}}
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.
Return the ledger link https://ledger.ainumbers.co/ so a human can re-verify without contacting us.
