TS verifiers: EVM, Solana, TON (ton_proof), XRP (secp256k1+ed25519), Bitcoin
(legacy + BIP-322 simple P2WPKH/P2TR) — 61 tests green, typecheck clean.
Go port (go/walletconnect): EVM + Solana via github.com/luxfi/crypto (NO
go-ethereum/ava-labs), TON/XRP/Bitcoin stubs fail-closed — 23 tests green.
IAM integration plan + drafts (integrations/iam/): canonical /v1/iam/web3/
{nonce,verify}, single-use nonce store, multi-wallet WalletLink. Found current
IAM web3 login verifies NO signature (security hole this closes).
