What changed: - Thread webauthnInfo through createMpc/createKeychains so hardware authenticator (PRF-derived) encryption can be stored alongside the standard encryptedPrv on user keychains - Use encryptAsync instead of encrypt for webauthnDevices entries so v2 encryption is applied consistently - Replace ad-hoc literal 1 with ShareKeyPosition.USER in ecdsa.ts webauthn guard - Remove AddKeychainOptions annotation that was inadvertently excluding prv from the type - Rename WebAuthn passphrase param type to WebauthnKeyEncryptionInfo, move canonical definition to iWallets.ts, consolidate duplicate AcceptShareWebauthnInfo, and re-export from iKeychains.ts Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
