Ports VowLib.sol, WitnessDirectory.sol, and IWitnessDirectory.sol to an Anchor program with byte-identical vow payload support. - ECDSA secp256k1 signature recovery via secp256k1_recover syscall - EVM event encode/decode (emitter | topic_count | topics | data) - Merkle tree verification with sorted-pair keccak256 hashing - EIP-712 bare-domain typed data hash for witness signatures - SignerSlot PDAs store 20-byte Ethereum addresses - process_vow_bare() library function (no Anchor coupling) for composability into downstream programs - TypeScript tests using Viem with ESNext/NodeNext configuration
