Function: verifyStateChain()

verifyStateChain(chain, opts?): VerifyResult

Verify the full transfer history of a statechain.

For each TransferRecord, verifies:

1. Chain continuity: party IDs and PKDs are linked hop-by-hop.
2. Transfer key lineage: derivePKdigest(transferKey, 0) === fromPublicKeyDigest.
3. Digest provenance: sha3_256(txBodyHex) === signedDigest. Prevents a malicious record from pairing valid signatures over one digest with unrelated txHex. Binds all signatures to the actual TX data.
4. SE blind signature: verifies blindedSignature over signedDigest.
5. Old-owner signature: verifies ownerSignature over signedDigest. Proves the old owner — not just the SE — authorised this state transition.

Then validates that currentOwner matches the last transfer recipient.
