Core package

xrpl-x402-core re-exports official x402 2.21.0 protocol schemas. The only locally owned models are XRPL-specific payload/extra/state records.

Important exports include:

• PaymentRequired, PaymentRequirements, PaymentPayload
• VerifyRequest, VerifyResponse, SettleRequest, SettleResponse
• ExactXRPLPayload, ExactXRPLExtra, XRPLSettlementState
• find_default_asset, invoice hashing, network and fingerprint helpers

XRP is represented by asset: "XRP" with drops. IOUs use their currency code and extra.issuer; decimals are not a protocol field.
