did:webvh DID Log Verifier

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 `verify_did_webvh_log`. Task: Verify a did:webvh self-certifying DID log: per-entry self-hash integrity, sequential versionId numbering, update-key-authorized Ed25519 signatures on every entry, deactivation status, and optional resolved-document match.
Call it with arguments: {"policy_parameters":{"did":"did:webvh:{SCID}:example.com:agents:alpha","did_log":[{"versionId":"1-e42e4191001ee7d68d48609c2f30b141bd0a38da21496378a29108720c435a56","versionTime":"2026-01-01T00:00:00Z","parameters":{"method":"did:webvh:1.0","scid":"QmScidPlaceholder1234567890abcdef1234567890abcdef1234567890","updateKeys":["did:key:z6MkfJpX7dP5KqfxbK9nN3ttWptKBjRGrCqJaW28zqBUnRjX"],"portable":false},"state":{"id":"did:webvh:{SCID}:example.com:agents:alpha","verificationMethod":[{"id":"did:webvh:{SCID}:example.com:agents:alpha#key-1","type":"Ed25519VerificationKey2020","controller":"did:webvh:{SCID}:example.com:agents:alpha","publicKeyMultibase":"z6MkfJpX7dP5KqfxbK9nN3ttWptKBjRGrCqJaW28zqBUnRjX"}]},"proof":[{"type":"DataIntegrityProof","cryptosuite":"eddsa-jcs-2022","verificationMethod":"did:key:z6MkfJpX7dP5KqfxbK9nN3ttWptKBjRGrCqJaW28zqBUnRjX","proofPurpose":"assertionMethod","proofValue":"1Ha0QDlQmx8Ch0H+ARATa1UU6jnghtm2LpqpV11m//W+42YnRwc9Bl8sx43JLmEskTzcSlngUcQdgFgrLK6lBg=="}]},{"versionId":"2-81ead391846f6088ddab084e2119b8304224a671b6c3f4b598605661ccd91196","versionTime":"2026-02-01T00:00:00Z","parameters":{"updateKeys":["did:key:z6MknN3rKuzKRmKyRQheSZ2n8yBKCwsTfZprYj1HBmF48bp2"]},"state":{"id":"did:webvh:{SCID}:example.com:agents:alpha","verificationMethod":[{"id":"did:webvh:{SCID}:example.com:agents:alpha#key-1","type":"Ed25519VerificationKey2020","controller":"did:webvh:{SCID}:example.com:agents:alpha","publicKeyMultibase":"z6MkfJpX7dP5KqfxbK9nN3ttWptKBjRGrCqJaW28zqBUnRjX"}],"service":[{"id":"did:webvh:{SCID}:example.com:agents:alpha#agent-endpoint","type":"AgentEndpoint","serviceEndpoint":"https://example.com/agents/alpha"}]},"proof":[{"type":"DataIntegrityProof","cryptosuite":"eddsa-jcs-2022","verificationMethod":"did:key:z6MkfJpX7dP5KqfxbK9nN3ttWptKBjRGrCqJaW28zqBUnRjX","proofPurpose":"assertionMethod","proofValue":"PUj6zxdMWvEQeQhhfCHShlQzgagicFXph2tFcQK9e3RGF6/8yHNr3ASsUTiHySBhfOWv1A7J3PnoVy4qEBVrCg=="}]}]}}
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.
