Implements a minimal smart contract for permanently linking decentralized identifiers (DIDs) to EVM-compatible addresses (H160). Features: - One-time, permanent DID-to-account binding - Bidirectional lookups (DID→Address, Address→DID) - DID format validation (must start with "did:key:") - Event emission on account linking - 9 unit tests covering all functionality This contract supports authnz-rs integration by providing on-chain verification of DID ownership for Substrate accounts. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
