every DID method, measured
did:web hardened with a verifiable, hash-linked key history.
New driver under the verification guarantee: ThisDID resolutions are double-checked in parallel against an independent upstream — for did:webvh, godiddy and archon — until the live match-rate earns graduation.
Each document version is entry-hashed and proof-signed in a did.jsonl log; the ThisDID wrapper adds a WebCrypto Ed25519 proof verifier so history is verified by ThisDID, not trusted. A DIF Recommended method.
