Introduces internal/xrpl, the bridge's XRP Ledger primitives package: - AddressFromPubKey / AccountIDFromPubKey: derive the canonical r-address from a 33-byte compressed-secp256k1 public key. Hash chain is RIPEMD160(SHA256(pubkey)), base58check-encoded with the XRPL alphabet + 0x00 version byte. Round-trips through the rubblelabs codec. - PreSign(PaymentUnsigned) → (32-byte digest, *SignCtx): builds a native XRP Payment, embeds the signing pubkey on the wire, returns the SHA-512Half of (0x53545800 || serialized_body) — exactly the message the MPC quorum must sign. - Finalize(DER, *SignCtx) → (signedBlob, txHash): attaches the DER signature to TxnSignature, returns the full wire-format binary blob (suitable for submit's tx_blob param as hex) and the canonical XRPL tx hash (SHA-512Half of 0x54584E00 || blob). - EncodeDERSignature(r, s): ASN.1 DER encode (r, s) with low-s normalization (rejects high-s as XRPL's tfFullyCanonicalSig requires) and the 0x00 leading-byte rule for INTEGERs with the MSB set. - CanonicalizeS / SHA512Half exposed for tests + future TrustSet path. Uses github.com/rubblelabs/ripple for the deep binary codec — every field-id, type-byte, and length-prefix detail is the library's responsibility. The bridge owns only the signing flow on top, so MPC ECDSA can stand in for the library's local-key Sign helper. Tests cover: canonical pubkey → r-address round-trip, rejection of bad pubkey lengths/prefixes, DER encoding of standard and high-bit cases, low-s flip for s > N/2, validation that high-s gets canonicalized in EncodeDERSignature, PreSign digest matching independent SHA512Half recomputation, full PreSign → Finalize round-trip via the parser.
