Yorke Rhodes	cb404cb85c	feat: implement checkpoint fraud proofs (#4277) ... ### Description Implements 4 categories of checkpoint fraud proofs for use in future validator slashing protocol: 1. **premature**: if a checkpoint index is greater than the corresponding mailbox count, it is fraudulent 2. **non local**: if a checkpoint origin does not match the checkpoint's mailbox domain, it is fraudulent 3. **message id**: if a checkpoint message ID differs from the actual message ID (verified by merkle proof) at the checkpoint index, it is fraudulent 4. **root**: if a checkpoint root differs from the actual root (verified by merkle proof + root reconstruction) at the checkpoint index, it is fraudulent Notably this is implemented independently from signature verification to allow for multiple checkpoint signing schemes to reuse the same checkpoint logic. ### Related issues - Touches https://github.com/hyperlane-xyz/hyperlane-monorepo/issues/3799 - See https://github.com/hyperlane-xyz/hyperlane-monorepo/pull/2431 for previous discussions ### Backward compatibility Yes ### Testing Unit testing with fixtures in `vectors/merkle.json` that are generated by the rust merkle tree and proof code	3 months ago
